Problems solved by technology

[0003] However, due to the fast breaking speed of the electromagnetic repulsion mechanism, the impact force it brings to itself and the circuit breaker is also large, so it is easy to fail
The existing fault diagnosis of electromagnetic repulsion mechanism still stays at the algorithm level, and there are few monitoring systems that can be practically applied

Abstract

The invention discloses a fault monitoring method, system and device for an electromagnetic repulsion mechanism and a readable storage medium. The signal features of a vibration signal sample set is extracted through employing a wavelet packet normalization energy method, the model training is carried out through employing the obtained signal features, a fault diagnosis model is obtained, a fault diagnosis threshold value of the diagnosis model is set, the electromagnetic repulsion mechanism is used as a monitoring object, the online monitoring of the electromagnetic repulsion mechanism is firstly achieved, the running state of the electromagnetic repulsion mechanism can be judged in real time, accordingly, faults are rapidly and accurately reduced, parameter and structure optimization of the electromagnetic repulsion mechanism is further guided, online monitoring can be achieved, whether a fault occurs or not and the type of the fault can be judged within several seconds after the electromagnetic repulsion mechanism acts, the state of the circuit breaker can be quickly and accurately judged through the opening vibration signal, and the method has certain practical engineering application value.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a fault monitoring method, system, equipment and readable storage medium of an electromagnetic repulsion mechanism. Background technique [0002] With the development of the economy and society, the safety of the power system is also facing more and more severe challenges, and the breaking of short-circuit current is an important part of it. However, the traditional mechanical structure circuit breaker can no longer meet the opening capacity and speed in some places, so a vacuum circuit breaker using electromagnetic repulsion mechanism has been applied. The breaking speed of the electromagnetic repulsion mechanism is fast and the time is short, which can meet the breaking requirements of the current short-circuit current. [0003] However, due to the fast breaking speed of the electromagnetic repulsion mechanism, the impact force it brings to itself and the circu...
