Abstract

PURPOSE:To shorten the time required for the preparation and the test of various tests, by providing a bushing, a tank connected to said bushing, and a circuit breaker which is incorporated in said tank and can be operated from the outside of the tank, and a fluid insulating material contained in the tank. CONSTITUTION:The tester is constituted by the main body of the tank 11, the bushing 12 which is provided on one side of said tank 11, and the circuit breaker 13 which is incorporated in the main body of the tank 11. Said circuit breaker 13 and the bushing 12 are electrically connected by a lead 14. The circuit breaker 13 is operated by an operating shaft 15. Said operating shaft 15 is driven by an operating cabinet provided at the outside of the main body of the tank 11. The fluid insulating material such as insulating oil and insulating gas SF6 are contained in said main body of the tank 11. In this constitution, since the switching of the test circuit can be accomplished by operating only the circuit breaker 13, the tet time can be shortened, and the availability of the expensive test equipment can be improved.
