Vacuum Interrupter, VIThe vacuum rate within the VI is very high

(approximately 5x10-5 Torr) and the spacing

between f ixed contact and movable

contact is about 6~20mm, depending on

the voltage.

The contacts are in a structure that arc can

easily be extinguished and the surfaces of

the contacts are made of special alloy (copper-

chromium) and the interior is completely sealed

to prevent loss of vacuum.

Therefore the wearing of the contacts can be

minimized in the event of short-circuit and the

arc energy by overvoltage or switching can be

reduced effectively.

E2 (List 1 or List3)

E2 (List3) is first proposed in the IEC 62271-100(2008) to improve the efficiency of the interrupting test. According to it the number of interrupting test T60 is increased instead of fewer number of T10 and T30 compared to the existing List1. List3 compared with the List1 maintains the equivalent of the test but has severe test conditions because 34% higher arc energy applied to the breaker. List3 is applied to Susol VCB series.

Basic functions and interrupting operation

Basic functions

Manual operation① Manual Charge

a) VL type: operate the charge handle 7-8 times as a fully stroke.b) VH type: Insert the charge handle into the handle slot first. Rotate the handle clockwise 40 times more and then charge

will be complete with a click sound.- When the closing spring is charged fully "CHARGED" is displayed at the charge indicator.

② Manual closinga) Pressing the ON button the breaker is closed.b) With the closing of the breaker "ON" is displayed at Close/Trip indicator and "DISCHARGED" at the charge indicator.

③ Manual tripa) Pressing the OFF button the breaker is opened.b) "OFF" is displayed at Close/Trip indicator.

Electric operation① Electric charge

The breaker is remotely closing with charging of closing spring. If the breaker trips the closing spring is automatically charged by gear motors.

② Electric closingRemote closing is operated by the closing coil.

③ Electric tripRemote trip can be operated by the trip coil or UVT coil.

Main contacts are operated by the energy of the spring mechanism and closing spring is charged by the motor in the mechanism.Breaker is closed by closing coil and tripped by trip coil.These operations are repeated in VCB as shown in the below sequence chart.

The interruption of vacuum interrupters

The interruption of VCB is carried out by the vacuum interrupters.Interrupter contacts as a key part made of copper - chromium (CuCr) material with spiral shape have low contact wear characteristics and withstand voltage is excellent.Spiral contacts make the arc generated between the surfaces of contacts rotated around the surface of contact by the induced magnetic field generated due to the spiral contact structure, which results in preventing local heating, thereby corruption and interrupting instantaneously.

The interruption of vacuum interrupters

Spiral contact structure (Radial magnetic field), using the force (F = j×B) generated by the interaction of the radial magnetic field caused by the current flowing through the arc between two contacts, disperse the arc energy evenly on the surface of contact by rotating the arc that is contracted by the pinch effect so as to minimize contact damage.The images show arc behavior during the arcing time of about 8ms by shooting with high-speed camera capable of shooting 10,000 frames per sec. (0.1ms/frame) by focusing on parts of the arcing time on the above graph and simultaneously measured arc voltage also represented to show arc state by section.

In case of using the flat contactany of the designs do not reflecton when contacts are opening thearc with high temperature iscontracted and fixed in the centerof the contacts,Which is calledpinch effect.To prevent the effect two kinds ofcontact shapes are designed.One is Axial magnetic field whichspreads the arc before itscontraction, and the other isRadial magnetic field whichpermits the contraction of the arcbut makes it rotated to dispersethe energy.Because contracted arc is shapedlike a cylinder it is calledContracted arc or columnar arc.

• When no current flows through the coil it gives the test current which does not cause the coil to operate to check whether the coil is disconnected or not.- If the test current flows normally: coil normal- If the test current does not flow through: coil disconnected

※ As it is connected in parallel with the control part of the coil the normal operation of the coil is not affected.※ Monitoring of the running coils is not possible.※ One test unit can monitor up to two coils.

1. Input voltage: AC/DC 75V~264V

2. Contact output1) 2×a contacts for Fail indication and 2×a contacts for Alarm2) 250Vac/10A Resistive, 30Vdc/10A Resistive

3. Disconnection test cycle is 12 seconds (Test LED blinks)

4. The default operationIf Fail happens (coil disconnected), Fail LED turns on and the Fail contacts become short state.If Fail happens three times in series, Alarm LED turns on and the Alarm contacts become short state.In order to clear the Alarm status push up DIP switch on the front and then push down it (Off → On → Off)

Technical data

Standard Use Environment for Susol VCBThe operation characteristic of Vacuum Circuit Breaker such as insulation and endurance is often influencedlargely by external environment and thus should be applied appropriately with conditions of the place whereit is used taken into consideration.

The following values are the limits have been set in accordance with IEC 62271-100 (IEC 62271-1)

Ambient Temperature- maximum temperature: +40℃- 24-hour average maximum temperature: +35℃- minimum temperature: -5℃

Altitude- 1000m or less above sea level

Relative Humidity- 24 hours average value: 95% or less

▒ If a standard circuit breaker is used in high temperature exceeding 40℃, you are advised to use it according to the current corrected for each level of ambient temperature in catalog.

▒ If used in conditions of high humidity, the dielectric strength or electric performance may be degraded.

▒ It is highly recommended to use a dust cover or anti-humid agent if it is used in dusty and humid conditions.

▒ Excessive vibration may cause a trip breaker such as connection fault or flaw on mechanical parts.

▒ If it is left ON or OFF for a long time, it is recommended to switch load current on a regular basis.

▒ It is recommend to put it in the sealed protection if corrosive gas is prevalent.

37

Special Use Environment

The circuit breaker is designed for use in standard use environment specified in Section 2. 1 of IEC62271-1.Concerning the special use environments as below the special use conditions are required to be considered, thus please contact us in advance.

- where altitude and ambient temperature are out of standard use environment.(-40℃)- where a strong sea breeze blows- when usually used in a humid place- where a lot of steam or oil steam exists- where explosive, flammable and other harmful gases might permeate the breaker- In a dusty place- where abnormal vibration or shock exists- where a lot of ice and snow exist- other special conditions

Withstand voltage compensation according to altitudeIf the breaker is used in areas of sea level higher than 1000m the degradation of insulationperformance should be taken into consideration.

Technical data

Ex) Selecting a breaker to be used in a place of 2500m above sea level with a rated voltage 7.2kV (correction parameter 1 applied)- correction parameter at 2500m is 1.2- criteria of withstand voltage by rated voltage:

Power Frequency Withstand Voltage (Ud) = 20kV, Impulse Withstand Voltage (Up) = 60kV- requirements withstand voltage criteria:

Power Frequency Withstand Voltage (Ud) = 20×1.2 = 24kV, Impulse Withstand Voltage (Up) = 72kVTherefore rated voltage 12kV breaker shall apply to satisfy the required withstand voltage.

Ex) To apply a breaker with a rated voltage 12kV to the place of 2,500m above sea level (correction parameter 2 applied)- correction parameter at 2500m is 0.825- dielectric strength of VCB : Power Frequency Withstand Voltage (Ud) = 28×0.825 = 23.1kV,

Impulse Withstand Voltage (Up) = 75×0.825 = 62kV/1.2×50 ㎲Therefore above breaker with rated voltage 12kV shall apply to rated voltage system 7.2kV at the altitude.

Comparison of GCB & VCB

In the system of medium voltage lines VCB uses a vacuum which is an eco friendly medium for arc extinguishing. It also offers excellent interrupting properties and ease of maintenance and has expanded the area to the scope of the GCB as the overlap increases.
