Current collection line circuit breaker fault troubleshooting method

Abstract

The invention is suitable for the technical field of circuit breakers, and provides a current collection line circuit breaker fault troubleshooting method, which comprises the following steps: S100, recording information of each mechanism in a circuit breaker and phenomena and problems of the circuit breaker when the corresponding mechanism is damaged; s200, recording the information of each shortcircuit breaker fault and maintenance; s300, establishing a fault database, and storing the recorded data into the database; by recording the information of the internal mechanism of the circuit breaker and the maintenance information of the circuit breaker, when the circuit breaker breaks down, searching can be carried out in the database according to the phenomenon when the circuit breaker breaks down and the phenomenon information, and the database inquires the corresponding mechanism according to the input information; moreover, the inquired mechanisms are arranged according to the maintenance frequency, and a worker can check the circuit breaker according to the sequence, so that the whole process is simple and convenient, and unnecessary time waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of circuit breakers, and in particular relates to a troubleshooting method for a circuit breaker fault of a collector line. Background technique [0002] A circuit breaker is 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. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy and start asynchronous motors infrequently. It can automatically cut off the circuit when serious overload, short circuit and undervoltage faults occur. Its function is equivalent to the combination of fuse switch and overhea...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a troubleshooting method for a circuit breaker fault on a collector line, aiming at solving the problem that when a circuit breaker fails on a collector circuit, most workers need to check the mechanisms in the circuit breaker one by one, and finally determine the fault point. The troubleshooting process is cumbersome, resulting in unnecessary waste of time
