H1-2
High reliability of the operating mechanism- Separate design of the main circuit from theoperating 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)
�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.
High interrupting performance Great operational safety

Manual chargeInsert the charge handle into the manual charge hole in the front of aVCB, and rotate it to clockwise over 40times and the chargecomplete with a metal sound.
Motor chargeIf you apply the control power to a VCB, the closing spring will becharged automatically by a motor and then the control power will beturned off by the built-in limit s/w. Please use the same controlvoltage for motor, Closing coil, Trip coil.

VI internal structure
Largely movable and fixed electrodes and main shield compose the Susol VI.The main components are shown in the following.
The vacuum rate within the VI is very high(approximately 5x10-5 Torr) and the spacing betweenfixed 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 contactsare made of special alloy (copper - chromium) and the interior is completely sealed to prevent lossof vacuum.Therefore the wearing of the contacts can be minimized in the event of short-circuit and the arcenergy by overvoltage or switching can be reduced effectively.

Basic functions and interrupting action
Interrupting action by VI
Spiral contact structure (Radial magnetic field ),using the force (F = j×B) generated by theinteraction of the radial magnetic field caused bythe current flowing through the arc between twocontacts, disperse the arc energy evenly on thesurface of contact by rotating the arc that iscontracted by the pinch effect so as to minimizecontact damage.The images show arc behavior during the arcingtime of about 8ms by shooting with high-speedcamera capable of shooting 10,000 frames persec.(0.1ms/frame) by focusing on parts of the arcingtime on the above graph and simultaneouslymeasured arc voltage also represented to show arcstate by section
In case of using the flatcontact any of the designsdo not reflect on whencontacts are opening the arcwith high temperature iscontracted and fixed in thecenter of the contacts,Which is called pinch effect.To prevent the effect twokinds of contact shapes aredesigned.One is Axial magnetic fieldwhich spreads the arcbefore its contraction, andthe other is Radial magneticfield whichpermits the contraction ofthe arc but makes it rotatedto disperse the energy.Because contracted arc isshaped like a cylinder it iscalled Contracted arc orcolumnar arc.

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

Vacuum Circuit Breaker for Power Plants
Power Plants VCB
H3
A product developed for water and thermal power plants due
to the revision and application of Kepco’s standard (ES150)
followed by the IEC standard revision. It has completed the
high capacity (40~50kA) VCB series for power plants by
securing higher breaking capacity, safety and reliability.
VCB Full OptionTo prevent fatal error, property and life loss caused from operator duringoperation, it is equipped with safety mechanisms such as shutter padlock.
Bushing applied for Window CT adaptationThe bushing provides sufficient strength to collaborate with the internal insulation and isadaptable with CT offering safety mechanically and electrically when applying large current.

��Position padlockIt is located at the screw hole to prevent the draw-in and out of a breakerfrom the present position(Disconnected, Test or Connected)
��Mechanical position indicatorIt is located in the lower part of a breaker to check the present position -Disconnected, Test or Connected- easily.
��Position interlockThe 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 breakerfrom the present position.
��Auto connectionWhen the breaker is moved to Test position from Disconnected positionthe connector for control powers is automatically connected. In case ofreverse moving of the breaker the connector is automaticallydisconnected.
��Code plateWhen the breaker is inserted to the cradle, if the ratings does not matchwith the cradle, it mechanically prevents the breaker from being insertedinto the cradle.

Vacuum Circuit Breaker for Nuclear Power Plants
H4-2
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.
Nuclear Power PlantsVacuum Circuit BreakerVacuum Circuit Breaker
VCB Full Option
To prevent fatal error, property andlife loss caused from operatorduring operation, it is equippedwith safety mechanisms such asshutter padlock.
Bushing applied forWindow CT adaptation
The bushing provides sufficientstrength to collaborate with theinternal insulation and is adaptablewith CT offering safety mechanicallyand electrically when applyinglarge current.
Satisfies earthquake andother internal environmentspecifications
During the lifespan of power stations (40yrs),it is designed to operate its fundamentalbreaking functions even under the mostsevere conditions like earthquake, which iscritical from safety perspectives. Thesetechnologies proven through tests thatcomply with KEPIC standard and relevantspecifications are to guarantee nuclearreactor safety.

��Position padlockIt is located at the screw hole to prevent the draw-in and out of a breakerfrom the present position(Disconnected, Test or Connected)
��Mechanical position indicatorIt is located in the lower part of a breaker to check the present position -Disconnected, Test or Connected- easily.
��Auto connectionWhen the breaker is moved to Test position from Disconnected position theconnector for control powers is automatically connected.In case of reverse moving of the breaker the connector is automaticallydisconnected.
��Reversible contact10 auxiliary switches are provided. 8 of them consist of reversible 8c whichcan be changed from a(b) to b(a). Factory composition is 5a3b. And theother 2 switches are supplied as 2b with early-b contact function
��Code plateWhen the breaker is inserted to the cradle, if the ratings does not matchwith the cradle, it mechanically prevents the breaker from being insertedinto the cradle.
��Auto dischargeIn case the breaker is drawn-out when the closing spring is charged in theposition-Disconnected, Test or Connected, or the breaker is moved toDisconnected position from Test position the closing spring shall beautomatically released.
