Circuit breaker automatic detection equipment and detection method

Abstract

The invention discloses circuit breaker automatic detection equipment and a detection method. The circuit breaker automatic detection equipment comprises a rack and a transmission mechanism, wherein the rack is provided with a first station, the first station is provided with opening distance overtravel detection probe groups, a lifting mechanism, a first clamping mechanism, a first switch-on switch-off mechanism and a simulated stationary contact mechanism; the opening distance overtravel detection probe groups are fixedly installed on the lifting mechanism and driven by the lifting mechanismto be in contact with various moving contacts, the simulated stationary contact mechanism comprises a drive piece provided with a cushion block, the cushion block simulates the shape of a stationarycontact and is driven to extend into or take back the installation position of the stationary contact of a circuit breaker. The detection method and the detection equipment capable of automatically detecting the opening distance, the overtravel parameter, the synchronism and the mechanical running-in of the circuit breaker are provided, and have the characteristics of high working efficiency and slight error.

Description

technical field [0001] The invention relates to the field of circuit breaker detection, in particular to an automatic detection device and detection method for a circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Before the circuit breaker leaves the factory, a series of performance tests must be done on the production line. Therefore, the test of the circuit breaker is an important link to ensure that the finished product is qualified to leave the factory. Parameter detection, mechanical running-in detection, synchronization test, etc. mostly rely on manual measurement and simple test fixtures to complete manual detection, but relying on manual operation, the measurement error is large, the operation is cumbersome, the detection efficiency is low, and there are saf...

Before the circuit breaker leaves the factory, a series of performance tests must be done on the production line. Therefore, the test of the circuit breaker is an important link to ensure that the finished product is qualified to leave the factory. Parameter detection, mechanical running-in detection, synchronization test, etc. mostly rely on manual measurement and simple test fixtures to complete manual detection, but relying on manual operation, the measurement error is large, the operation is cumbersome, the detection efficiency is low, and there are safety hazards in manual wiring. Low, and missed detection and misjudgment occur from time to time
