Switch cabinet static contact assembly quality detection device and detection method

Abstract

The invention provides a switch cabinet static contact assembly quality detection device and detection method. The detection device comprises a chassis vehicle; a visible light emitter, which is installed on the static contact and emits a visible light beam coaxial with the static contact; and a light-transmitting plate which is installed on the chassis vehicle and receives the visible light beamsto form light spots on the light-transmitting plate and is provided with marks representing the standard positions of the moving contacts of the circuit breaker so as to judge the assembly quality ofthe static contacts through the deviation between the marks and the light spots. The visible light emitter can emit a visible light beam coaxial with the static contact, wherein the visible light beam represents the installation position of the static contact, the light-transmitting plate can receive the visible light beam to form a light spot, and the light-transmitting plate is provided with amark used for representing the standard position of the moving contact of the circuit breaker. Therefore, the assembly quality of the static contact can be judged through the deviation between the mark and the light spot, the larger the deviation between the mark and the light spot is, the poorer the assembly quality of the static contact is, and otherwise, the better the assembly quality of the static contact is.

Description

technical field [0001] The invention relates to a detection device and a detection method for the assembly quality of a static contact of a switch cabinet. Background technique [0002] During the assembly process of the switchgear, due to the processing errors of parts and the accumulation of errors during the assembly process of the switchgear body, when the switchgear is equipped with cabinets, it is easy to appear that the installation size error of the static contacts cannot be controlled, which may cause the static contact and the dynamic contact. Accidents are caused by poor contact of contacts. It is difficult to accurately measure the installation deviation direction and size of static contacts in actual assembly, which reduces the interchangeability of switch cabinets and cabinets, brings greater trouble to assembly and debugging, and also greatly affects product quality. This problem is a difficult problem in switchgear assembly inspection. [0003] In this regar...

Problems solved by technology

[0004] Although the above-mentioned inspection vehicle can measure the installation position deviation of the static contact, once marks are left on the cross centering plate, it will affect the next use. After a measurement is completed, it basically needs to be replaced, and the reusability rate is low, which will increase The cost of batch testing
