GAS INSULATED COMPOSITE SWITCHGEAR

摘要

PROBLEM TO BE SOLVED: To simplify a gas monitoring system and to improve insulation deterioration caused by the attachment of foreign metallic substances to a spacer, by forming a circuit-breaker container and a disconnector container and a disconnector container in a continuous single space, and making their insulating gases a single gas compartment. SOLUTION: Concerning to a circuit-breaker 1, a circuit-breaking unit 4 is put horizontally in a cylindrical circuit-breaker container 3 filled up with an insulating gas composed of SF6 gas, and the circuit-breaking unit 6 is fixed to the circuit-breaking container 3 with an insulating supporting cylinder 7. Besides, concerning to a disconnector 2, a disconnecting unit 12 is put in a cylindrical disconnector container 11 filled up with an insulating gas, and the circuit-breaker container 3 and the disconnector container 11 are constituted so as to form a continuous single space. Accordingly, an insulating gas put in the disconnector container 11 and an insulating gas put in the circuit-breaker container 3 are the same insulating gas. As the result, between the circuit-breaker container and the disconnector container becomes a single gas compartment, and the gas monitoring system is simplified. Besides, insulation deterioration by the attachment of foreign metallic substances is improved since any spacer is not provided in the vicinity.
