SOLID INSULATED TYPE VACUUM CIRCUIT BREAKER

摘要

PURPOSE: A solid insulated shield combination type vacuum circuit breaker is provided to exclude the use of SF6(Sulfur hexafluoride) gas by injection-molding epoxy insulation materials to have an insulated housing. CONSTITUTION: A fixed connection conductor(110) is connected to a lead-in cable. A movable connection conductor(120) is electrically connected to a disconnecting switch. A vacuum valve(200) is located between the fixed connection conductor and the movable connection conductor. A pair of main shield units(310,320) are bended to surround the edges of the vacuum valve. An insulated housing(400) surrounds the outer sides of the fixed connection conductor, the movable connection conductor, and the vacuum valve.
