Plug connector switching method for 10KV circuit breaker mechanical characteristic test

Abstract

The invention provides a plug connector switching method for a mechanical characteristic test of a 10KV circuit breaker. A switching control module (9) of a test instrument, an output end interface (10) and an input end interface (8), wherein the output end interface (10) and the input end interface (8) are connected with the switching control module (9); the output end interface comprises an aviation male plug (11); a circuit board (902) of the switching control module is provided with a plurality of switch units connected with pins of the aviation male plug in a one-to-one correspondence manner; when a mechanical characteristic test is carried out on the 10KV circuit breaker, the aviation male plug is in butt joint with an aviation female plug of the 10KV circuit breaker, and the switching control module switches the on-off state of the switching tube according to a set switching strategy, so that the pin definition of the aviation male plug is matched with a current test item; the device can be easily butted with an aviation female plug of the circuit breaker, operation by professionals is not needed, and test time and labor cost can be saved; and meanwhile, correct wiring is realized, wrong wiring is avoided, and the safety of a person, a circuit breaker and a mechanical characteristic instrument is further ensured.

Description

technical field [0001] The invention relates to the technical field of power grid operation and maintenance, in particular to a plug-in switching method for testing the mechanical characteristics of a 10KV circuit breaker. Background technique [0002] The existing 10kV circuit breaker mechanical characteristic test method usually leads the test line from the output end of the mechanical characteristic tester, and then connects the test line to the aviation plug pin of the 10kV circuit breaker through the clamp on the test line, so as to control the circuit breaker to realize the electromagnet Unlocking, motor energy storage, closing and opening functions. The disadvantage is that there are many clamps connected to the pins of the secondary plug, which not only requires professional wiring personnel and long wiring time, but also has low work efficiency and high labor costs; short circuit with adjacent pins, resulting in personal injury, damage to the circuit breaker, and d...
