Automatic detector and method for mechanical performance of push-pull circuit breaker

Abstract

This invention offers an auto detecting device and method of mechanical performance of push-pull circuit breaker. The device mainly include clamping fixture, working control device, servo driver, precise linear die set, servocontrol card, force sensor, testing bar, voltage sensor, clock and picking card. Measure by voltage: circuit breaker move forward and press down, voltage sensor testing jump signal of phase voltage. Mating photoelectricity code disc get locking position of a phase, the force sensor get the change of press force, in order to get force-curve, connect force and lock force. Mating photoelectricity get locking position of a phase, single-phase spare distance, the isochromism of three phase. Pull-push measurement: circuit breaker move backward and press down, voltage sensor testing jump signal of phase voltage. Mating clock get starting signal of every phase, force sensor measure the change of push-pull force, push-pull force curve, breaking force and out of knock force, mating clock get out of knock time for a single phase and the isochromism of three phase. The invention has merits of various function, high speed, high accuracy and high credibility.

Description

technical field [0001] The invention relates to an automatic detection device and method for the mechanical properties of a push-pull circuit breaker, belonging to the testing technology of the mechanical properties of the circuit breaker. Background technique [0002] Circuit breakers are widely used in various electrical equipment in industry, agriculture, national defense and daily life. It is the most widely used safety device; at the same time, it is also an important automatic control equipment. The push-pull circuit breaker is a power supply protection and automatic control device used in aviation, ships and special vehicles. Its mechanical properties have an important impact on operating aircraft, ships and vehicles. It must be guaranteed in the production process. technical indicators. [0003] At present, the measurement of the mechanical performance of the circuit breaker is to start the circuit breaker to work in manual mode, and ...

AI Technical Summary

Problems solved by technology

[0003] At present, the measurement of the mechanical performance of the circuit breaker is to let the circuit breaker start to work in the manual mode, and there are generally two ways to measure it. One is to install the sensor directly on the exposed contact for the unsealed or open circuit breaker. measurement; the other is to use a vibration sensor for measurement, and the measurement parameters of both methods are extremely limited

The measurement of the mechanical properties of the push-pull circuit breaker is the final inspection of the finished product. The circuit breaker is in a completely sealed state, and the measurement parameters are many and complicated. It is difficult to achieve a single measurement method and manual method.
