GAS INSULATED SWITCHING APPARATUS

摘要

A bushing in air is supported upright on one end of a horizontal tank, and a center conductor extending in the bushing is connected to one terminal of a circuit breaker accommodated in the tank. A tank of a disconnecting switch is disposed to extend in the axial direction of the circuit breaker tank and is coupled to the other end thereof through an annular current transformer and also via gas-tight means. A bushing support tank disposed to extend along the ground surface is coupled via gas-tight means to the other end of the disconnecting switch tank. Another bushing in air is supported upright on the bushing support tank. A grounding switch is provided inside the bushing support tank. A center conductor extending in the second bushing is connected to an arrester through a removable conductor.
