10kV centrally installed switchgear circuit breaker tester

Abstract

The invention relates to a 10KV centrally installed switchgear circuit breaker tester. The instrument comprises an instrument shell, an output terminal, a display panel, an operation panel and a powerswitch are sequentially arranged at the upper part of the instrument shell from left to right; the output terminal is connected with the integrated board through a terminal connecting wire; the integrated board camera is arranged in the instrument shell; the display panel is connected with the integrated board through a display panel connecting line. The operation panel is connected with the integrated board through an operation panel connecting line. The power switch is connected with the energy storage power supply and the integrated board. An aviation joint connecting wire is arranged below the integrated board; wherein one end of the aviation connector connecting wire is connected with the instrument shell, the other end of the aviation connector connecting wire is connected with theaviation connector, the aviation connector is arranged on the instrument shell, the energy storage power supply is arranged in the instrument shell and is further connected with the energy storage interface through the power supply connecting wire, and the energy storage interface is arranged on the instrument shell. The invention has the advantages of reasonable structure, high working efficiencyand reduced wiring work.

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
