摘要
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.关键词
