Safety information 2.2 ESD-sensitive components



Description 3

The SICROWBAR DC overvoltage protection is a symmetric thyristor switch which protects the inductances from overvoltage and discharges capacitances in a targeted manner by switching on an external load resistor. This allows the thyristors and diodes of a primary power converter to be protected. The thyristor switch can be switched on even without an overvoltage using the additional module ("Fast de-energization option"). The response to overvoltage or fast de-energization is measured by integrated monitoring of the voltage via the de-energization resistor, and a signal with secure electrical separation is issued.

Area of application: The device is used to protect excitation units (excitation windings and power converters) on synchronous motors and generators against overvoltages or to dissipate the exciting current in a controlled way using a de-energization resistor if an interrupt occurs. The device can also be used for discharging DC link capacitors.

Figure 3-1 View

Description 3.1 Overview


3.1 Overview

Figure 3-2 Schematic circuit diagram

Method of operation SICROWBAR DC overvoltage protection monitors the voltage at terminals C and D of the power converter or the excitation winding. Once the operate voltage has been reached, the de-energization resistor is connected in parallel to the excitation winding by a thyristor. This means that the energy in the excitation winding can be safely dissipated in the excitation unit even if an interrupt occurs.

Repeating the switching operation is only permitted after a sufficient cooling time has elapsed. See Chapter Restart time (recovery time) (Page 65). The current flow in the thyristor is measured via the voltage at the de-energization resistor and is signaled with secure electrical separation. The recommended thermostatic switch measures any overheating of the de-energization resistor. The additional fast de-energization option makes it possible to trigger ignition even if there is no overvoltage.

Design The components of the device are:

Power connections (copper bars) C, D

Two thyristors V1, V2 connected antiparallel

Firing module which ignites the thyristor in the relevant blocking direction at the operate voltage (800 V, 1,200 V, 1,600 V, 1,900 V, 2,200 V, 2,600 V, and 3,000 V).

Description 3.3 Functions


3.3 Functions

3.3.1 Monitoring functions

3.3.1.1 Voltage measurement for de-energization/discharge resistor The voltage measurement module is connected to busbar C via series resistors (R11, R12) and to the external de-energization/discharge resistor via terminal XEM1.

The following signal states are generated by querying the voltage between busbar C and terminal XEW1:

Current flow (terminal 35, 42) LOW= voltage below the threshold (no current flow) HIGH= voltage is above the threshold (current flow) See Two-tier terminal 30 to 47 (Page 35).

Inverse current flow (terminal 34, 40) Terminal 35, 42 inverted

Relays K1 to K3: drop out when current is flowing For the position of the contacts, see the relay contacts table

These signals are used to deactivate the power converter after it responds or to set the current to zero.

For details on the switching thresholds, see Table 3-5 Switching thresholds and series resistors of the "current flow" monitoring function (Page 24).

When the "current flow" signal stops being displayed, this does not mean that the electric circuit is actually current free. Restarting with capacitor DC links is only permitted once current=0. It is possible to delay the disappearance of the "current flow" signal using adjustable pulse stretching to bridge the wait time.

See Chapter Settings for switches S1 to S5 for "current flow" pulse stretching (Page 38).

3.3.1.2 Wire break in supply line XEW1 The interrupt (wire break) in external line XEW1 to the de-energization/discharge resistor is reported in 3 ways.

Open-circuit detection terminal 44: LOW= wire break HIGH= no wire break See Two-tier terminal 30 to 47 (Page 35).

Relay K4: drops out if wire breaks For the position of the contacts, see Terminals 50 to 64 (relays 1 to 5) (Page 36).

Both these signals can be used as an alarm in the higher-level control.



Detecting the wire break via the "current flow" signal status See chapter Settings for switch S6 for linking the inverse current flow to wire break (Page 37). If switch S6 is closed, the "current flow" signal is set to HIGH and the "inverse current flow" signal to LOW if a wire breaks.

The response time for the "wire break" signal is <3 s.

3.3.1.3 Overload at de-energization/discharge resistor The thermostatic switch (connectors 3 and 4) responds to overheating of the de-energization/discharge resistor.

The signal occurs as follows:

Terminal 46 becomes LOW

Relay K5 drops out. The connection between terminals 63 and 64 is interrupted.

Connector 3 +4 has secure electrical separation to electronics and ground for line voltage up to 1,200 V. For details, see Chapter Terminals 3 and 4 (Page 34)

3.3.1.4 Switching on and failure of the electronic power supply When the electronic power supply is switched on, all outputs are switched off for around 1.5 s (high impedance) and all normally open contacts of the relays are open. If the voltage drops below 18 V, the same status is produced.

Note for the configuration:

We recommend using the outputs as follows to ensure safety against the wire breaking:

Table 3- 3 Outputs of the voltage measurement module

Output Description Recommendation K1 to K5 Relay contacts Only use normally open contact 34, 40 Inverse current flow As active enabling signal 44 Inverse wire break As active enabling signal 46 Inverse overload As active enabling signal 35, 42 Current flow Relay coil from 24 V

Using the normally closed contacts of the relay is not recommended.

The use (of one or more signals) as recommended (the right-hand column of the table above) ensures that the power converter or the higher-level control of the system is switched off when a wire breaks in a signal line.



3.3.2 Fast de-energization option The fast de-energization option is an assembled PCB which is built into the device.

It makes it possible to trip the device at any time, even without overvoltage present on terminals C, D. The function is tripped by activating at least one of the 3 terminals XSE1, XSE2, and XSE3. Safe ignition is possible if at least 5 to 10% of the operate voltage is present at connections C, D.

Up to 3 devices with different currents are available for each operate voltage.

3.4.1.2 Selection when using different power converters If a SIMOREG DC-MASTER/SINAMICS DCM is not used, the values of the selected thyristors and the exciter coil must be taken into account.



Definitions

UAN Operate voltage of the firing circuit. Uline Line side line-to-line connection voltage (3AC) of the excitation unit. UMAX Voltage limit, determined by the smaller value of the thyristor blocking

voltage or blocking voltage of the power converter, or by the maximum permissible voltage at the exciter coil.

UPERIODIC Periodic overvoltage consisting of the line peak voltage and the TSE peaks (from the hole-storage effect). Typical values are Uline × √2 × 1.8 to Uline x √ 2 × 2

ULIM We recommend the following safety clearance to protect the components: ULim < UMax × 0.9

Dimensioning The operate voltage UAn (ignition voltage) is specified as follows:

Uperiodic < UAn < ULim < UMax

The following thus applies: Uperiodic < UAn < ULim < UMax × 0.9

The device must be arranged close to the UMax designated element (short connecting lines).

The critical current gradient (according to the selection table) must not be exceeded. In general, adherence to the gradient is guaranteed by the inductances of the resistors and supply lines. Additional inductances are not recommended as this would reduce the efficiency of the voltage limitation.



3.4.2 Selection according to maximum current The complete arrangement comprises a SICROWBAR DC overvoltage protection and de-energization/discharge resistor. The dimensioning of this resistor in relation to current carrying capacity is not described in detail here, but two basic conditions must be taken into account:

The resistance value must be so low that even at the highest load current, the voltage is still under the destruction limit of the supplying power converter and the excitation winding (operate voltage of the SICROWBAR).

The resistance value must be high enough that the maximum current is not reached by

the thyristor (see Table 3-1 Ordering data (Page 15)). The arrangement of fuses on the power converter must also be taken into consideration.

The design notes from standard IEEE 421.6 (draft) must also be applied for protecting the excitation winding of synchronous generators.

A distinction is made between two cases:

Without option G11: The device is only used for surge suppression.

With option G11: The device is also used for fast de-energization.

(Option G11 = assembled fast de-energization PCB)

3.4.2.1 Without option G11 If the device is used for surge suppression, the selection of the device and the dimensioning of the de-energization resistor must be considered together.

The device must be selected so that its maximum pulse current based on the dimensions of the resistor is not exceeded. See Chapter Typical load current characteristic for the three device power stages (Page 65).

3.4.2.2 With option G11 If the device is used for fast de-energization of synchronous generators,

the maximum current which occurs in the excitation circuit lmax can be calculated as follows:

IE,N is the nominal excitation current. For simplicity, it is also calculated with 3 • IE,N The chronological sequence of the current through the SICROWBAR DC corresponds to that

Description 3.5 Modules


described in Chapter Typical load current characteristic for the three device power stages (Page 65). The calculated lmax must be smaller than the maximum permissible pulse current of the device. See also Device order numbers (Page 15).

3.4.2.3 Operation in a voltage DC link with a capacitor For connection suggestion, see also Figure 6-2 DC link discharge connection suggestion (Page 32).

The device can also be used for discharging DC link capacitors.

The operate voltage must be far enough above the maximum working voltage of the voltage DC link. The SICROWBAR DC is generally ignited specifically via the fast de-energization option to discharge the DC link. It is only possible to remove the thyristors once the holding current has been undercut by around 0.5 A. This means that it is necessary to allow for a short operation interrupt.

3.5 Modules

3.5.1 Voltage measurement

3.5.1.1 Switching thresholds and series resistors of the "current flow" monitoring function The voltage measurement for the de-energization/discharge resistor is connected to busbar C via the series resistors (R11, R12) and to the external de-energization/discharge resistor via terminal XEM1. This means that the voltage between the ends of the resistor is monitored and output as the "current flow" signal. Above a certain voltage between C and XEW1 (for details, see the device data), the output at terminal 34 (inverse current flow) switches from HIGH to LOW, the output at terminal 35 (current flow) switches from LOW to HIGH, and the relay contacts K1 to K3 drop out.

This input is configured for secure electrical separation with a rated insulation voltage of up to 1,200 V. See Technical data (Page 61)

For a description of overload at de-energization/discharge resistor, see Monitoring functions (Page 18).

An external thermostatic switch (or several in series) can be connected to this clamp-type terminal. This provides secondary protection against overloading the resistor and must be configured for the temperature conditions.

For details on the thermostatic switch, see De-energization/discharge resistor and thermostatic switch (Page 71).

HIGH = with feed of 24 V = 19.8 - 23.5 V, resilient up to 80 mA, short-circuit proof to electronics ground. LOW = 0 - 1 V, resilient up to 400 mA, short-circuit proof to +24 V.

The lines (terminal numbers 32 to 47) are "DVC-A (safety extra-low voltage)" and must be laid with secure electrical separation from all lines which carry line voltage.

These must be laid so that they are as separate from the electric power cables as possible. The maximum line length that can be connected is 30 m.

The device is grounded via the protective conductor connection, see Chapter PE terminal (Page 40).

Note for the configuration:

Because up to 3.2 V can drop out at internal protective elements of the outputs at 80 mA, the required operating voltage must be present across terminals 34, 40, 44, and 46 to ensure that external relays can be activated safely. We recommend activating external relays via terminals 35 and 42 as they are LOW active and the relay coils are directly connected to the P24 supply. See also Arrangement of terminals (Page 33).

The maximum allowable line length is 300 m.

When routing the lines of relay contacts with safety extra-low voltage (terminals 50 to 64), it is important to ensure secure electrical separation of power supply cords. If the relay contacts (terminals 50 to 64) are operated with voltages >60 V, here too, it is important to ensure secure electrical separation from the lines of terminals 32 to 47.

If relays K1 to K5 (lines of terminal numbers 50 to 64) are operated with "DVC-A (safety extra-low voltage)" and "DVC-C (supply voltages)", secure electrical separation from each other must be ensured.



6.3.4 Settings for switch S6 for linking the inverse current flow to wire break Switch S6 must only be operated when the power unit is switched off. Closing switch S6 can link the "current flow" and "inverse current flow" signals to the "wire break" signal so that if a wire break occurs (in the wiring to the de-energization resistor) "STR current flow" is signaled. We recommend this for all systems in which a separate evaluation of the "inverse wire break" signal (relay 4 "wire break") does not take place. This does not change the logical statuses at the "inverse wire break" and "inverse overload" outputs.

Factory delivery status = switch S6 open. Always solder closed contacts.

Example for switching positions S1 to S6

Alternative option for linking the "wire break" signal to the "current flow" signal If the relay contacts are connected as follows, the enabling circuit will be interrupted if a wire break occurs. K1, K2, K3 = current flow K4 = wire break The function at the "current flow" and "wire break" relay outputs is not changed

6.3.5 Settings for switches S1 to S5 for "current flow" pulse stretching Switches S1 to S5 may only be actuated when the power unit is switched off. Closing switches S1 to S5 can extend the active status of the "current flow" and "inverse current flow" signals. Times ranging from 1 mm to 1,500 ms can be set.

Commissioning 7

NOTICE

This device contains electrostatic sensitive devices.

Before coming into contact with modules the operator must be electrostatically discharged in order to protect electronic components against high voltages that are produced by electrostatic charging. The easiest way to do this is to touch a conductive, grounded object immediately beforehand (for example, the bare metal part of a control cabinet).

Modules must not come into contact with highly insulating materials (such as plastic sheets, insulated desktops, or articles of clothing manufactured from man-made fibers).

Modules may be placed only on conductive surfaces.

WARNING

Dangerous voltages.

The device is at a hazardous voltage. Failure to comply with these Operating Instructions can lead to death, serious injury, and material damage. Only qualified personnel who are familiar with all the safety instructions in this description, as well as the installation, operating, and maintenance instructions, should carry out work on this device. Perfect, safe, and reliable operation of the device is conditional upon it having been transported, stored, mounted, and installed correctly, as well as carefully operated and serviced. The device is at a hazardous voltage even when the line contactor of the power converter device is open. Before starting maintenance or servicing work, shut down and lock all current sources for the power converter feed. These instructions are not exhaustive and as such cannot outline all the measures required in order to operate the device safely. Where necessary, additional information or instructions may be required for special applications. If particular problems arise which these Operating Instructions do not cover in enough detail, please contact your local Siemens office. The use of parts which have not been approved for repairing this device or the handling of the device by unqualified personnel can lead to dangerous conditions, death, serious injury, or substantial damage to the equipment.

Observe all warnings in Chapter Safety information (Page 9) of these Operating Instructions.

Commissioning


Commissioning:

If errors are output at the "current flow" and "inverse current flow" signals when a wire break occurs, close switch S6. See Settings for switch S6 for linking the inverse current flow to wire break (Page 37).

Connect the terminals of the output signals to the power converter. Engineering information: If current is flowing in the de-energization resistor, the power converter must be switched off at least temporarily (20 ms).

Test the "wire break" signal by interrupting the line at XEW1. The response to the "wire break" signal can last up to 3 s.

Test the "overload" signal by interrupting the lines to the thermostatic switch (if one is fitted) at terminals 3 and 4.

Set pulse stretching using S1 to S5 if necessary. See Settings for switches S1 to S5 for "current flow" pulse stretching (Page 38).

Test the behavior in the event of an electronic power supply failure. See Switching on and failure of the electronic power supply (Page 19).

The device does not have any software and there are therefore no parameters to set.


Operation 8

The DC overvoltage protection does not contain any operator controls which must be actuated during operation.

Please note the following during operation:

Cooling times after de-energization processes must be observed. See Restart time (recovery time) (Page 65).

Operation



Maintenance 9

WARNING

Dangerous voltages.

When operating electrical devices, it is inevitable that certain components will carry dangerous voltages.

Dangerous voltage levels may be present at the signaling relays at the customer's site.

Therefore, failure to handle the units properly can result in death or serious physical injury as well as extensive property damage.

When performing maintenance on this unit, you should therefore observe all information provided in this chapter as well as any notices attached to the product itself.

Only qualified personnel who are familiar with all the safety instructions in this description, as well as the assembly, operating, and maintenance instructions, should carry out maintenance work on this unit.

Before carrying out maintenance work, it must be ensured that the unit is disconnected from all power supplies, disabled, and grounded. Before they are shut down, both the converter unit and the excitation winding are subject to dangerous voltage levels; A hazardous voltage is present even if the converter device contactor is open.

The capacitors of the primary power converter or DC power converter connected in parallel can continue to carry a dangerous voltage for up to a minute after disconnection. Opening the device is therefore only permitted after an appropriate wait time.

Ensure safe isolation from the supply before commencing work. See Safety information (Page 9).

Use authorized spare parts only.

The device must be provided with extensive protection measures against contamination in order to prevent voltage flashovers and, therefore, destruction. Dust and foreign bodies, which are brought in by the cooling-air flow in particular, must be thoroughly removed at certain intervals; this depends on the rate of accumulation of dirt, but should be carried out at least every 12 months. The device must be blown out with dry compressed air at a maximum of 1 bar, or cleaned using a vacuum cleaner. The screw connections (also the protective conductor connections) must be retightened each time that maintenance work is carried out.

B.3 Restart time (recovery time)

Single tripping is periodically possible after 30 min wait time.

After being triggered twice in a time period <30 min, a recovery time of 300 min is required.

* = Tripping the SICROWBAR DC overvoltage protection

There are multiple cases in which current flows through the SICROWBAR and thus causes the external resistor to heat up:

Technical specifications and drawings B.3 Restart time (recovery time)


1. De-energization according to e-potency in fast de-energization if it is not possible to feed back via the power converter.

2. Generator slips: The generator is disconnected from the line supply system after 200 ms for mechanical reasons. A current of 11 kA can flow at this time. The resistor should be thermally configured for 2 x 200 ms.

3. Ignited by the overvoltage pulse on the line. The power converter consequently feeds to the de-energization resistor. Significant and sustained power loss occurs depending on the load point. This operation should be avoided by immediately limiting the power converter to remove the thyristor in SICROWBAR.

The following components are described as examples:

Discharge resistor Company: GINO Type: 3PR3001-1K-1R17 (1.17 Ω) Other types: 3PR3001-1M 2R3, 3PR3801-1B 0R24, 3PR3401-1F 0R6

Thermostatic switch: Company: Microtherm Type: R28-160 05 J Ö TR/STD 52N121934

Selecting the de-energization resistor After determining the resistance value according to Chapter Selection according to maximum current (Page 23), the size (frame size) of the resistor must be selected so that the highest permissible temperature of the cast iron elements (approx. 300 °C) is not exceeded at the highest load that occurs (duty cycle, worst-case scenarios).

Selecting the thermostatic switch The connection lines of the thermostatic switch must be configured for short-term heating to 300 °C. The lines must be laid so that they are in hot air currents as little as possible. The switching threshold of the thermostatic switch must be set so as to prevent damage (crack formation) to the cast iron elements.

Additional information

Additional documents D.1 De-energization/discharge resistor and thermostatic switch


The connections are made using Faston tabs (6.3 mm).

Lines for making connections with Faston plugs: Nickel wire 1.5 mm², NiMoGi/ m type, flexible, white

Installing the thermostatic switch The de-energization resistor and the thermostatic switch must be installed correctly so that the rising temperature can be correctly detected and to ensure that the thermostatic switch functions. The lines must be laid in parallel.

The thermostatic switch is mounted on a mounting bracket in the center of the upper crossbar. The vertical distance from the cast iron elements must be at least 19 mm. This gives an air clearance for double/enforced insulation for 1,200 V for an installation altitude of up to 2,775 m. The heat-resistant lines from the thermostatic switch are laid to a junction terminal.

The lines must be laid from the junction terminal to the APCB with one of the following:

NYM-J (sheathed cable 300 V)

H07R (line 750 V)

If multiple de-energization resistors are to be connected in parallel, we recommend installing a thermostatic switch on each resistor and connecting them in series. The cumulative resistance of the external thermostatic switches and lines connected in series must not exceed 100 Ω.

Additional notes:

The bracket must be reinforced in the corners so that it is not easy to bend out of shape either after or during installation.

A second mounting bracket must also be installed for fastening the line.

A complete package can be ordered from GINO AG using the order number 132501. It contains the following components:
