CIRCUIT BREAKER DEVICE APPLIED WITH ARC QUENCH VACUUM INTERRUPTER CAPABLE OF PREVENTING THE DAMAGE OF A MAIN OPERATIONAL CONTACT POINT BY INDUCING ARC CURRENTS TO OTHER GROUND POINTS

摘要

PURPOSE: A circuit breaker device applied with an arc quench vacuum interrupter is provided to prevent the generation of contamination due to insulating oil.;CONSTITUTION: An operational space part(101) is arranged in a housing(100) and is filled with insulating oil. A main operational contact point conducts currents inside the operational space part. A vacuum valve(300) is in connection with the main operational contact point in order to introduce or block arc currents instead of the main operational contact point. A power transferring member(400) transfers operational driving force to the main operational contact point and the vacuum valve at the external side of the housing. The housing is formed by injecting epoxy resin.;COPYRIGHT KIPO 2012
