1,Summary

GN2-40.5/630A indoor high voltage isolating switch is the three-phase ac high-voltage electric equipment, in the exchange electric system used for nominal voltage 40.5kV, rated frequency 50Hz or 60Hz, are for the high voltage line to carry on change-over switching in no-load cases, and what carried on the electrical isolation or connected with the current carrying high voltage line to the high-pressure electrical apparatus of high voltage bus, circuit breaker,etc. that is overhauled was used.

2,Type meaning and design

Staples: GN2-40.5/400A, GN2-40.5/630, GN2-40.5/1250A, GN2-40.5/1600A, GN2-40.5/2000A

3,Structural features

Disconnecting switch this, for the intersection of three-phase and linkage type, board, pillar electrical insulator, conductive several switch blade quiet to touch first class part, make up from underframe, axis of rotation, linkage. The axis of rotation is mounted on the underframe, weld linkage edition on the axle, link with switch blade through the electrical insulator of draw bar. Both ends of axis of rotation stretches out the underframe, any one end of it can link with actuating mechanism and carry on dividing, switching-in. All right level, vertical or slope and install of this serial disconnecting switches.
