초록
Power distribution system requires the transformer with higher capacity than ever, but this ever, but this may be the cause of the increasing of short circuit current in contrast to conventional one when short-circuit accident is occurred. Therefore molded case circuit breaker improved in aspects of interrupting capacity of short circuit current in this system is needed. The arrangement and quality of the material of grids in arc quenching room are also designed optimally by the analysis of arc driving forces.
