摘要

根据变电站瓷支柱绝缘子带电检测缺陷的实际需求，以220 kV瓷支柱绝缘子为研究对象，深入研究了裂纹长度、裂纹形状和激振位置对瓷支柱绝缘子振动检测的影响。首先阐述了瓷支柱绝缘子内部缺陷振动检测的基本原理，然后建立瓷支柱绝缘子有限元数值分析模型，利用脉冲信号模拟锤击进行瞬态分析，并搭建实验平台进行测试分析。仿真和实验结果表明：裂纹长度越大，在功率谱图上表现为正常频率区间内的峰值降低，故障区间内的峰值所对应固有频率左移，激振点远离裂纹侧时波峰的加速度响应谱值出现小幅度的减小，但不会影响对瓷支柱绝缘子内部缺陷的判断，裂纹的连续分布特性和形状不影响振动检测的灵敏度。

Abstract

Based on the practical requirement for live detection of defects in porcelain pillar insulators of substation and with the 220 kV porcelain pillar insulators as the research object

the influence of crack length

crack shape and excitation position on vibration detection of pillar insulators is deeply studied. First

the basic principle of internal defect vibration detection of the porcelain pillar insulators is described.Then

the finite element numerical analysis model of the porcelian pillar inculators is set up.The pulse signal is used to simulate hammering for transient analysis and an experimental platform is set up for test analysis.Both simulation and experimental results show that when the larger the crack length is

the peak in the normal frequency range will be decreased on the power spectral graph

and the natural frequencies corresponding to the peak in the fault range is shifted to the left. In case of the excitation point far from the carck side

the acceleration response spectrum value of the wave peak exhibits a slight decrease

but does not affect the judgement to the internal defect of the porcelian pillar insulators. Also

the continuous distribution characteristics and shape of the crack will not affect the vibration detection sensitivity.
