Auxiliary plug board for circuit breaker test

Abstract

An embodiment of the invention provides an auxiliary plug board for a circuit breaker test. The auxiliary plug board for the circuit breaker test comprises a board body, wherein a contact plane is arranged on the board body; connection holes which correspond to pins on an aviation plug are formed in the contact plane and are connected with an output end of the auxiliary plug board; fixed columns which are in clamped connection with fixed bolts on the aviation plug are arranged on two sides of the board body; waterproof projections are arranged at the edge of the contact plane on the board body; and an infrared sensing module is further arranged on the contact plane. The auxiliary plug board is arranged between the aviation plug and followed-up power supply and control equipment, and directional transmission of different data in the aviation plug can be realized, so that a cover plate of a circuit breaker mechanism does not require to be opened during test; the number of operators is reduced; labor and time costs are reduced; closing and locking are not required to be relieved manually in a test process; and therefore, operation risks of maintainers are reduced.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to an auxiliary plugboard for circuit breaker testing. Background technique [0002] When testing 10kV and 35kV circuit breakers (mainly including the minimum operating voltage of opening and closing, coil resistance, time and speed characteristics, etc.), the personnel must first disassemble the mechanism cover, pull the closing and locking electromagnet core ejector and After being fixed by a wire clip, the closing mechanical interlock can be released manually to carry out follow-up work. [0003] Such a traditional test method will lead to the following problems: the cover plate of the circuit breaker mechanism needs to be disassembled for each test, and it needs to be completed by the two teams of the variable inspection and the high-level test team, which takes up a lot of maintenance time and human resources; at the same time, the test needs to be processed The closing and l...
