Vacuum contactor comprehensive performance test board and test method of vacuum contactor comprehensive performance

Abstract

The invention discloses a vacuum contactor comprehensive performance test board which is characterized by comprising an input/output loop unit, a signal detection unit, an analytical control unit and a voltage-regulating unit. The input/output loop unit is used for inputting power and supplying the same for each unit; the signal detection unit is used for detecting output voltage and coil current of a contactor and sending the output voltage and the coil current to the analytical control unit to be analyzed and judged; the analytical control unit is used for analyzing and judging multiple dynamic tests of the contactor; and the voltage-regulating unit is used for controlling clockwise/anticlockwise rotation of a motor through signals analyzed by the analytical control unit, so that a voltage regulator can be boosted and released to release voltage when the contactor pulls in voltage. With the method, test results of the multiple dynamic detects of the contactor are accurate and visual, testing time is short, and conventional connection troubles during tests are reduced; one equipment with the contactor is provided with the tests and analyses of multiple performance parameters at a time; and intellectualization of incoming goods detection is improved, and professional requirements on an detection personnel is lowered.

Description

technical field [0001] The invention relates to a testing technology for coal mine explosion-proof product components, in particular to a vacuum contactor comprehensive performance testing platform and testing method. Background technique [0002] The performance test of the vacuum contactor involves the principles and technologies of electricity, magnetism, heat, mechanics, materials, electrical contact, reliability, etc. under various working conditions, and its dynamic process presents nonlinear, complex and uncertain , The electrical characteristics and mechanical properties of the contactor are the main indicators of the contactor design, which directly affect the dynamic characteristics of the contactor. However, the existing inspection methods for incoming contactors are basically simple power-on tests and direct observation with naked eyes. At present, the method of checking and evaluating the performance of contactors for incoming goods is to use type withstand vol...
