Problems solved by technology

[0002] During the test of the 10kV central cabinet circuit breaker, the switch needs to be pulled to the maintenance position. At this time, the aviation plug between the handcart circuit breaker and the switch cabinet is disconnected, the energy storage power supply is disconnected, the closing circuit is blocked, and manual energy storage is required. , open the front panel of the handcart circuit breaker, and remove the blocking relay, but the relay is difficult to remove, time-consuming and laborious, and when wiring, the internal terminals of the aviation plug are dense, which is prone to accidental touch, resulting in short-circuit damage to the circuit breaker or inaccurate test data , In addition, two tests of switching characteristics and insulation resistance are required for circuit breaker debugging. The conventional method is to use two sets of instruments to test in turn. The disconnection and wiring in the middle are cumbersome and time-consuming. We combine the functions of the two sets of instruments to reduce the work of disconnection , save time; therefore, it is very necessary to provide a 10KV central cabinet circuit breaker tester with reasonable structure, high work efficiency and reduced wiring work
