Abstract

The current of the electromagnet coil during the operation of circuit breaker contains a wealth of circuit breaker status information

and the coil current has the characteristics of simple collection

easy analysis and good reproducibility.In this paper

after the coil current is divided into four stages

a new fault diagnosis method based on coil current of circuit breaker is proposed;Five failures of circuit breaker are simulated

then a fault diagnosis mode of circuit breaker based on the support vector machine is established and the results show that the method can realize the mechanical fault diagnosis of circuit breaker more accurately and effectively.
