Abstract

The invention discloses a relay detection system based on an improved guide rail to avoid magnetic field interference. The relay detection system comprises a computer, a relay comprehensive parameter tester and a sorting machine which are connected sequentially, the sorting machine comprises the guide rail made of a non-ferrous material and further comprises an armature, a push clamp and an elastic piece correspondingly arranged in a to-be-detected relay; in an energized testing process, an iron core and a coil of the relay produce magnetic field attraction to attract the armature and push the push clamp, so that a contact on the elastic piece is closed, and a pull-in voltage testing result is output by the computer after being acquired by the relay comprehensive parameter tester. The guide rail made of the non-ferric material is adopted, the relay cannot produce the interference magnetic field in the energized testing process, so that the change affecting the pull-in voltage of the relay can be eliminated, and with the adoption of the detection system in the research method, test inaccuracy caused by external magnetic field interference in the efficient testing process is avoided.

Description

technical field

[0001] The invention relates to a relay detection system based on an improved guide rail to avoid magnetic field interference, and belongs to the technical field of relay testing. Background technique

[0002] The relay is one of the main components of power control and protection equipment. Its reliable operation is a necessary condition to ensure the accurate operation of the device. As the national standard and industry standard increase the starting voltage requirements of the equipment, the relay needs to be classified and screened according to the specified voltage range. . The use of automatic detection has become the first choice. Not only is the classification accurate and reliable, but it can also greatly improve efficiency. However, during the power-on test, it was found that the use of iron guide rails affects the irregular fluctuation of the pull-in voltage, resulting in inaccurate test results. Therefore, based on the above reasons, there is an...
