VACUUM CIRCUIT BREAKER
[ Compasion table for VCB (Short circuit test) ]
Compasion table for VCB (Short circuit test)
High reliability of the operating mechanism - Separate design of the main circuit from the operating mechanism. - Adopt the toggle link method. - Improved the reliability of electric circuit. - Adopt the rapid auto-reclosing method as a standard option. (O-0.3sec.-CO-3min.-CO)
High interrupting performance
Great operational safety
�Make short of the interrupting time. (3cycles) �Increase the rated short-circuit withstand characteristics. (1sec. to 3sec.)
�Reinforce the insulation in the conduct, by adopting the molded housing in each phase. �Built in the device making the contacts open first when draw in and out. �Adopt the tulip-shape connection between the cradle and the VCB.

Fixed electrode
Fixed seal cup
Fixed shield
Contacts
Bellows shield
Arc shield
Ceramic
Bellows
Movable seal cup
The vacuum rate within the VI is very high(approximately 5x10-5 Torr) and the spacing between fixed 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.
H1-44
Basic functions and interrupting action Interrupting action by VI
In case of using the flat contact any of the designs do not reflect on when contacts are opening the arc with high temperature is contracted and fixed in the center of the contacts, Which is called pinch effect. To prevent the effect two kinds of contact shapes are designed. One is Axial magnetic field which spreads the arc before its contraction, and the other is Radial magnetic field which permits the contraction of the arc but makes it rotated to disperse the energy. Because contracted arc is shaped like a cylinder it is called Contracted arc or columnar arc. Arc voltage waveforms and arc image captured during arcing time
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

Vacuum Circuit Breaker for MCSG Features and Structure Features �Module type VCB �Convenient especially for fabricating MCSG - Housing is designed like VCB compartment style - MCSG panel can be easily constructed if combined with Low voltage compartment, Busbar compartment and Cable compartment.
�Convenient for maintenance and offering high safely - Earthing switch can be operated from outside of the panel, and which makes earthing of 3 phases at the same time. - Without opening the compartment panel door, breaker can be drawn in or out electrically or manually
�Main functions - Breaker : draw- in or out electrically or manually - Compartment : 3-positions
�Standard - IEC 62271-100

�Mechanical position indicator It is located in the lower part of a breaker to check the present position Disconnected, Test or Connected- easily.
�Position interlock The breaker is locked in each position-Disconnected, Test or Connected, thus it is necessory to release the lock before draw-in or out of a breaker from the present position.
�Auto connection When the breaker is moved to Test position from Disconnected position the connector for control powers is automatically connected. In case of reverse moving of the breaker the connector is automatically disconnected.
�Code plate When the breaker is inserted to the cradle, if the ratings does not match with the cradle, it mechanically prevents the breaker from being inserted into the cradle.

H4-11
Vacuum Circuit Breaker Nuclear Power Plants It was developed for KEPCO nuclear power stations. This breaker satisfies quality, safety measures (secure from earthquake and other environments), and surge protection class complies with “1E-CLASS” ±provisions. It is featured with high breaking technologies, safety, and reliability by applying our own vacuum interrupters (50KA) approved by ANSI standard tests.
H4-2
Vacuum Circuit Breakers for Nuclear Power Plants
VCB Full Option To prevent fatal error, property and life loss caused from operator during operation, it is equipped with safety mechanisms such as shutter padlock.
Bushing applied for Window CT adaptation The bushing provides sufficient strength to collaborate with the internal insulation and is adaptable with CT offering safety mechanically and electrically when applying large current.
Satisfies earthquake and other internal environment specifications During the lifespan of power stations (40yrs), it is designed to operate its fundamental breaking functions even under the most severe conditions like earthquake, which is critical from safety perspectives. These technologies proven through tests that comply with KEPIC standard and relevant specifications are to guarantee nuclear reactor safety. H4-3

Vacuum Circuit Breaker for Nuclear Power Plants Accessories Accessories for breakers �Position padlock It is located at the screw hole to prevent the draw-in and out of a breaker from the present position(Disconnected, Test or Connected)
�Mechanical position indicator It is located in the lower part of a breaker to check the present position Disconnected, Test or Connected- easily.
�Auto connection When the breaker is moved to Test position from Disconnected position the connector for control powers is automatically connected. In case of reverse moving of the breaker the connector is automatically disconnected.
�Reversible contact 10 auxiliary switches are provided. 8 of them consist of reversible 8c which can be changed from a(b) to b(a). Factory composition is 5a3b. And the other 2 switches are supplied as 2b with early-b contact function
�Code plate When the breaker is inserted to the cradle, if the ratings does not match with the cradle, it mechanically prevents the breaker from being inserted into the cradle.
�Auto discharge In case the breaker is drawn-out when the closing spring is charged in the position-Disconnected, Test or Connected, or the breaker is moved to Disconnected position from Test position the closing spring shall be automatically released.
