摘要

近年来

电力系统中高压瓷套开裂事故的发生严重影响了电力系统的运行安全

须对高压瓷套进行有效检测以确保电网安全运行。文中首先从理论方面论证了振动法检测高压瓷套缺陷的可行性

然后设计实验对完好和损坏的高压瓷套进行模态实验

通过分析各阶模态固有频率的变化

最终得到振动法检测高压瓷套缺陷的判断方法

为高压瓷套的振动法检测技术的后续研究和应用推广提供了重要依据。

Abstract

In recent years

the cracking accident of high voltage porcelain in power system has seriously affected the operation safety of power system

and it is necessary to detect the high voltage porcelain bushing effectively to ensure the safe operation of power system.In this paper

the feasibility of the vibration method for detecting the defects of high voltage porcelain bushing is demonstrated in theory

and then the experiment is designed to carry out the modal experiment of the intact and damaged porcelain bushing.By analyzing the change of the natural frequency of each mode

the method of vibration detection is finally obtained.It provides an important basis for the further research and application of the vibration detection technology of high voltage porcelain bushing.
