摘要

目前主要基于振动信号来实现有载分接开关的状态监测和故障诊断。通过搭建有载分接开关故障模拟试验平台

针对某厂生产的主流CM型和CV型有载分接开关

开展了紧固件松动故障、弹簧动能不足故障、触头磨损故障和制动失效故障等常见故障模拟试验;并且为了反映不同的故障严重程度

针对每种故障都根据实际情况设置了不同梯度类型。研究了典型故障条件下故障模拟试验方法

得到典型故障条件下振动信号时域图和频谱图。研究结果表明:不同故障状态的时域波形和频谱图存在差异

表现出不同特点

通过故障模拟试验监测的振动信号可以对典型机械故障进行有效判断。

Abstract

At present

mainly based on the vibration signal to achieve on-load tap changer status monitoring andfault diagnosis. In this paper

through the construction of on-load tap changer fault simulation test platform

for themainstream CM and CV-type on-load tap changer

the fasteners loose fault

spring kinetic energy failure

contactwear and dynamic failure as well as other common fault simulation tests are carried out;And in order to reflect thedifferent severity of the fault

according to the actual situation for each fault

a different gradient type is set. The faultsimulation test method under typical fault condition is studied

and the time domain diagram and spectrum of vibra-tion signal under typical fault condition are obtained. The results show that the time-domain waveforms and spec-trums of different fault states are different and show different characteristics. The vibration signals can be effectivelyjudged by the fault simulation test.
