1.1. CUBICLE ELEMENTS

The cubicle is made up of a series of independent compartments:

Tank: Sealed compartment which houses the busbar and the switching and breaking elements, where the insulating medium is SF6.

The tank has a membrane to allow gases to escape in the event of an internal arc.

CAUTION

Do not refill the switchgear

Figure 1.2: Tank Each tank has a manometer for checking the gas pressure, which can easily be seen from outside the cubicle. The manometer scale is divided into different colors: red, grey and green. For safe operation, the needle must be in the green zone of the corresponding temperature band.

Switch-Disconnector and Grounding Switch: This component has three positions: closed, open and grounded. The operation is carried out using the actuating lever on 2 different shafts: one for the switch (switching between the closed and open positions); and another for the grounding switch (which switches between the open and grounded positions) on the feeder cables, and in the case of fuse protection cubicles, on the six fuse-holder clamps.

These elements are operated independently, i.e., their actuation speed does not depend on the speed of the manual operation.

Vacuum Circuit-Breaker: The CGMCOSMOS-V cubicle’s circuit-breaker uses vacuum switching technology.

The circuit-breaker is actuated by means of the push-button on the front of the cubicle. For manual operation, springs must be charged with the corresponding lever.

To ensure that the isolating distance is adequate, the CGMCOSMOS-V circuit-breaker cubicle has a disconnector-grounding switch as standard with the circuit-breaker. This element is operated using a specific lever depending on the type of driving mechanism.

Driving Mechanism Compartment: This is the compartment in which the switch-disconnector or the circuit-breaker is actuated, depending on the type of cubicle. The mimic diagram for the MV main circuit is displayed on the cover of this compartment.

The mimic diagram includes all the position indicators for the actuators.

The driving mechanisms can be replaced (due to improved characteristics) in any of the three switch-disconnector positions. These positions can be blocked on the B, BM and BR driving mechanisms by means of a padlockable coupling device, whether or not the cubicle is operating.

1.1.1. ekorVPIS - Voltage Presence Indication Unit

The ekorVPIS unit displays three signals, which correspond to each of the phases. The presence of voltage is indicated in each phase by means of flashing indicators.

The ekorVPIS unit indicates the presence of voltage in the operating range specified in the IEC 61958 standard.

The ekorVPIS unit displays the following indications:

Display each of the indicator phases The numbering corresponds to the order of the phases, from left to right, seen from the front of the cubicle. Each phase has a test point for checking the phase balance between cubicles.

The purpose of the test points for the three phases and ground is to make it easier to check the phase balance[4] between cubicles. Any universal comparator which complies with specifications of standard IEC 61958 can be used for this purpose.

NOTE

If the indicators do not light up, use other means to check that there is no voltage.

1.1.2. ekorSAS - Acoustic Grounding Prevention Alarm Unit

The ekorSAS acoustic alarm is associated with the ekorVPIS voltage presence indicator and actuation of the grounding shaft. The alarm is activated when there is voltage in the cubicle's MV feeder and the lever is inserted in the grounding switch shaft. A sound then indicates that a short-circuit or zero voltage may occur in the grid if the operation is carried out. Operation of the unit is assured within the same operating range as the ekorVPIS unit associated with it.

[4] See section 5.1. Checking Voltage Presence and Phase Balance.

Ground test point This is only used for comparing the phases.

Voltage presence indicator A flashing light indicates the presence of voltage in that phase.

4.3. FASTENING TO THE FLOOR

Before assembling the cubicles, the floor must be carefully leveled to prevent any deformation which may make it difficult to connect the cubicles to one another.

The cubicles can be fastened to the floor in two ways:

4.3.1. Floor Fastening on a Profile

If the floor of the Transformer Substation is not sufficiently uniform, it is advisable to install the MV cubicle assembly on an auxiliary profile, to make it easier to connect them. This profile, which can be supplied to order, must be anchored to the floor using expansion screws.

4.3.2. Fastening to the Floor by Anchoring

If the floor of the Transformer Substation is even enough, it is advisable to install the MV cubicle assembly directly anchored to the floor.

The sequence for anchoring the cubicles to the floor is as follows:

1. The cubicle's switch must be in the grounded position[7].

NOTE

By default, the cubicles are supplied with the switch in grounded position.

2. Remove the cable compartment cover, using the central handle on the cover to pull

it up and forward as indicated in the figure.

3. Anchor the first cubicle to the floor of the Transformer Substation using screws through the holes made in the base for this purpose. This will prevent vibrations or movements due to short-circuits, possible flooding of the Transformer Substation, etc. Take the following dimensions and figures into account.

4.6. CABLE CONNECTION

The MV incoming and outgoing feeders are linked to the transformer or other cubicles via cables. These cables and the corresponding bushings on the CGMCOSMOS system cubicles can be connected with simple (plug-in) or reinforced (screw-in) connecting points, either IEC type or IEEE-386 compliant.

CAUTION

Never touch live connectors, not even screened connectors. Screening does not constitute a protection against direct contact.

When the equipment is in service and a reserve cubicle is left with voltage in the upper busbar and without the cables in the lower bushings, insulating plugs must be placed in the bushings or close the grounding switch and lock that position with a padlock.

4.6.1. Horizontal Front Connection

1. Close the grounding switch. 2. Remove the cover to access the cable compartment. 3. Connect the terminals on the front bushings and secure the cables using the cable

support and clamp. 4. Connect the terminal ground connectors, if applicable, and the cable screen ground

connectors. 5. Put the cable compartment cover back in place.

NOTE

The clamp has two positions, depending on the cable diameter.

5.10.1. Padlock Interlock

Each actuation shaft can be locked with a maximum of three standardized padlocks, with a maximum handle diameter of between 0.3 inches (8 mm) and 0.4 inches (11 mm).

Figure 5.79: Locking with a Padlock on Feeder Cubicles

5.10.2. Lock Interlock

The cubicles are designed to incorporate optional blocks of locks for the grounding switch, whether open or closed. Examples of Lock Interlocks (optional): Lock 1: Grounding switch interlocked in open position. It avoids setting the switch to

the "grounded" position until the key for the low-voltage disconnector lock has been recovered.

Lock 2: Grounding switch interlocked in closed position (ALWAYS INTERLOCK for

works without voltage). It prevents anyone from accidentally opening the grounding switch by removing the ground from the cable.

6. MAINTENANCE

DANGER

For safety reasons, maintenance operations performed directly on the driving mechanism must be performed WITHOUT any actuating lever inserted

CAUTION


NOTE

Switchgear is guaranteed against SF6 leakage for 30 years

The live parts of the CGMCOSMOS cubicle main circuit and switching equipment do not require inspection or maintenance, as they are completely insulated in SF6 and therefore unaffected by the external environment. There is no restriction on maintenance of the breaking components.

The operating mechanism for the CGMCOSMOS system switching equipment does not require lubrication for correct operation throughout its estimated lifetime.

These mechanisms must be inspected when used under extreme conditions (dust, salt, pollution). It is advisable to carry out at least one operation during the inspections.

Components manufactured from galvanized sheet steel have been painted to ensure their resistance to corrosion. Any scratches, dents or similar on them must be repaired to prevent corrosion. 6.1. VOLTAGE PRESENCE INDICATOR TEST

To test the ekorVPIS voltage presence indicator, connect it to a 110 Vac / 230 Vac power supply. To do this, disconnect it from the cubicle and, using 4 mm terminals, apply voltage between the test point for the phase to be checked and the ground test point. Polarity does not apply to the 110 Vac / 230 Vac connection, so the phase and neutral can be connected either way. If a flashing signal is observed, the indicator is working correctly. To test the indicator correctly, this check should be carried out for all three phases.

The ekorVPIS unit can be replaced if necessary. To do so, remove the two screws on the top right and bottom left of the indicator. The indicator can then be disconnected from the base without needing to power down the feeder.

6.2. ACOUSTIC GROUNDING PREVENTION ALARM TEST

To test that the ekorSAS acoustic alarm is working correctly, connect the ekorVPIS voltage presence indicator to 110 Vac / 230 Vac with 4 mm terminals, which are placed in the indicator between the ground test point and the test point for the L1 phase. Maintain the auxiliary power for 5 minutes, after which time the lever is inserted in the grounding switch shaft in order to carry out the operation. The alarm starts to sound and continues to sound for at least 30 seconds. It will stop when the lever is removed.

The ekorSAS alarm can be replaced if necessary, since it is joined to the associated units with two friction-fit PCB connectors:

One 3-pin connector, polarized for the Voltage Presence Indicator. One 2-pin connector for the lever microswitch.

The procedure is as follows:

Remove the screws which hold the upper covering panel and remove it. Remove the driving mechanism cover. Gently press the lower fastening flanges on the ekorSAS unit to remove it. Undo both connectors and replace the damaged unit; then connect it to the lever

microswitch (2-pin connector) and the voltage indicator (polarized 3-pin connector).

The driving mechanisms and other elements outside the gas tank may require preventive maintenance; the frequency of this maintenance depends on the existing environmental conditions (harsh environments, dust, extreme temperatures, etc.), and should be established based on the installer's experience and its responsibility.

The maintenance should take place every 5 years or 2000 operating cycles, unless, based on the conditions of use, the user, together with Ormazabal’s Technical - Commercial Department, consider otherwise.

NOTE

For further information on the recommended Preventive Maintenance sequence for CGMCOSMOS-V, please contact Ormazabal’s Technical-Commercial Department.

7.2. ENVIRONMENTAL INFORMATION

CGMCOSMOS cubicles are defined as a sealed, pressurized system which contains sulphur hexafluoride (SF6)

[14].

SF6 is included in the Kyoto Protocol list of greenhouse gases. SF6 has a GWP (Global Warming Potential) of 22,200 units. (TAR, IPCC 2001)

At the end of the product's life, the SF6 contained in it must be recovered for processing and recycling, to prevent it being released into the atmosphere. Extracting and handling of SF6 must be carried out by qualified personnel, using a sealed piercing system. For the usage and handling of the SF6, the indications listed in IEC 62271-303 must be followed. The management and treatment of the rest of materials must be carried out in accordance with the country’s current legislation. 7.3. ELECTRICAL CHARACTERISTICS OF THE DRIVING MECHANISMS
