GIS振动机理及固有频率研究
Research on vibration mechanism and natural frequency in GIS
摘要
Abstract
There is great advantage when the vibration signal is used to GIS ( gas insulated switchgear) for condition monitoring and fault diagnosis.This paper researches the vibration characteristic when the GIS operates in normal con-ditions from the two aspects of electromagnetic force and magnetostriction.To explain the feasibility and necessity of condition monitoring and fault diagnosis of GIS through vibration method, this paper classifies and analyzes the abnor-mal vibration.Natural frequency is the main factor that affects the vibration of GIS.The method of GIS modal analysis is researched in the paper.Different GIS air cell, model establishment and boundary conditions are analyzed.Natural frequency is calculated through modal analysis.The result is consistent with the modal test which certificates the cor-rectness of modal analysis.关键词
