Description

Technical field:

[0001] The invention relates to a tester for a sulfur hexafluoride circuit breaker, in particular to a tester that can know the working state and defective parts of the circuit breaker in time, reduce the failure rate, improve the working efficiency and safety of the circuit breaker, and improve the pertinence of maintenance And online monitors for sulfur hexafluoride circuit breakers that reduce maintenance costs. Background technique:

[0002] Sulfur hexafluoride circuit breakers have been widely used in the power industry and are necessary high-voltage breaking products for large substations. The structure of the existing sulfur hexafluoride circuit breaker is that there is an insulating and sealed casing. In the insulating and sealing casing, there are upper insulating rods and lower insulating rods connected to the terminals of the current transformer. The front ends of the upper insulating rods and the lower insulating rods are respectively Equipped w...
