Abstract
By molding a plurality of vacuum valves (7), (13) having differing functions together with an input member (3) and an output member (21) en bloc in a resin layer (23) to form a switch gear (1), the present invention seeks to achieve dielectric strength without resorting to the use of SF6 gas, while rendering the whole device more compact and reducing both the number of parts and the man hours required for molding.
Claims15
A switch gear, comprising:
- a switching apparatus having a vacuum circuit breaker and a vacuum disconnector;
- an input member of said switching apparatus wherein electric power is input from an exterior;
- an output member of said switching apparatus wherein electric power is output to said exterior;
- and
- said switching apparatus being molded in a resin layer together with said input member and said output member, said input and output members forming a t-junction inside the molded resin layer and outside the vacuum circuit breaker and the vacuum disconnector.
