Description
technical field [0001] The invention relates to a power frequency withstand voltage testing device for a 10kV high voltage circuit breaker, in particular to a power frequency withstand voltage primary wiring device for a 10kV high voltage circuit breaker used for a multifunctional testing station. Background technique [0002] At present, when high-voltage testers conduct power frequency withstand voltage tests on 10kV high-voltage circuit breakers, they connect the test line at one end of the 3 poles of the 10kV high-voltage circuit breaker, and connect the other poles to ground, and then conduct power frequency withstand voltage tests. . When replacing the other pole for testing, it is necessary to replace the test line of the high-voltage circuit breaker again. If repeated tests are to be performed, the wiring needs to be disconnected repeatedly. Therefore, the current 10kV high-voltage circuit breaker pole-to-ground and pole-to-pole power frequency withstand voltage tes...
