Abstract

The invention relates to a breaker press-pull testing stand and a test method thereof, and solves the technical problems that a present press-pull type breaker test process is low in efficiency, highin cost and low in accuracy. The testing stand comprises a casing, a PLC, a two-position five-way solenoid valve, a cylinder and a clamp, the cylinder is connected with first and second magnetic switches, and a telescopic rod of the cylinder is connected with a magnet ring; the first magnetic switch and a first coil on the two-position five-way solenoid valve are connected in series and then connected between a first voltage pulse output port and a GND port of the PLC, and the second magnetic switch and a second coil on the two-position five-way solenoid valve are connected in series and thenconnected between a second voltage pulse output port and the GND port of the PLC; and a node between the first magnetic switch and the first coil on the two-position five-way solenoid valve is connected to a first switching value input port, a node between the second magnetic switch and the second coil on the two-position five-way solenoid valve is connected to a second switching value input port,and a gas outlet of the two-position five-way solenoid valve is connected with the cylinder. The testing stand and test method thereof can be widely applied to the technical field of reliability testof breakers.

Description

technical field [0001] The invention relates to the reliability test of a circuit breaker in the field of aerospace technology, in particular to a circuit breaker pressure-pull test bench and a test method. Background technique [0002] In the electrical equipment in the field of aerospace technology, the push-pull circuit breaker is widely used. When the circuit in the power distribution system is overloaded or short-circuited, the push-pull circuit breaker can be automatically disconnected to play a protective role. The main brand of push-pull circuit breaker is KLIXON, see the content of the following website for details. http: / / www.aictrade.com / Product / ProductShow.asp? ID=117. The Chinese invention patent application whose application publication number is CN101765897A discloses a push-pull circuit breaker structure. This website also discloses an aviation circuit breaker: https: / / detail.1688.com / offer / 541112760197.html? spm=a312h.7841636.1998813769.d_pic_5.umUbYr. ...
