Abstract

This paper describes constructions, applications and features of the Toshiba´s new concept 145 kV switchgear. This switchgear has an integration composed of live tank type gas circuit breaker, live tank type disconnector(s) and earthing switch. To realize the integration of the circuit breaker and the disconnector(s), one body hydraulic operating mechanism is developed for dedicating plural number of switchgear contacts. The above configuration lead to a compact air-insulated-substation which has less space and requires less maintenance work.
