摘要

从断路器电磁铁线圈电流和振动信号中分别提取信号特征

是实现断路器状态评估的可靠方法。然而断路器实际运行中的故障类型复杂多样

只靠单一信号可能无法准确实现其状态评估

因此提出一种基于不同信号特征融合的断路器状态评估方法

分析表明

该方法有利于实现断路器在复杂故障前提下的状态评估;对信号融合后的特征量进行了优化分析

结果显示

优化后的特征量依然能够准确实现断路器状态评估。

Abstract

Extracting features from the electromagnet coil current signal and vibration signal is a reliable method torealize the condition evaluation of the circuit breaker. However

the fault types of the circuit breaker are complex anddiverse when it is in actual operation

so only use one signal may not be able to achieve its condition evaluation.Therefore

this paper presents a new method to evaluate the condition of circuit breaker based on the fusion of differ-ent signal features

and the analysis shows that the method is more advantageous to realize the state condition of cir-cuit breaker under the condition of complex fault

this paper also makes optimization analysis on the fused features

the results show that the optimized feature can also be used to evaluate the condition of the circuit breaker.
