Abstract

The invention discloses a system for testing mechanical properties of an integral circuit breaker, which comprises a host computer and an interface board is arranged on the host computer, wherein the interface board is provided with a testing line, an AC-DC terminal, a speed testing terminal, a vibration testing terminal, a direct current voltage testing terminal, an alternating current voltage testing terminal, an A-phase fracture, a B-phase fracture, a C-phase fracture and a common port terminal, wherein the interface board is connected with a sensor through the testing line. The sensor is provided with a bracket and a magnetic base. The system has abundant program control functions, wherein the sensor includes the triggering mode, the channel selection, the triggering level, and a sampling time base, a recording parameter block and the like which can be set through program control, and also includes incomparable abundant triggering functions. The system provides an ideal and effective testing tool for carrying out the overhaul of the state of a high-voltage circuit breaker for an electric power system, can be used for testing the mechanical properties of the circuit breaker on line, and performs data storage, analysis and comparison so as to quickly and accurately diagnose the health condition of the circuit breaker on line.

Description

technical field [0001] The invention relates to a circuit breaker testing system, in particular to an integrated circuit breaker mechanical characteristic testing system capable of on-line fault diagnosis for electric high-voltage circuit breakers. Background technique [0002] The high-voltage circuit breaker is an important circuit breaker device in the power system, and it is responsible for the dual tasks of controlling and protecting the power system. In actual work, the power system requires high-voltage circuit breakers to be able to open and close quickly and smoothly, so as to ensure the dual functions of controlling and protecting the power system. The degree of reliability is an important factor in determining the safe power supply of the power system, and it is very important to keep the circuit breaker in a healthy state all the time. [0003] According to the statistical survey of high-voltage circuit breaker failures, most of the failures of circuit breakers ...
