Abstract
It is important to study the vibration characteristics of GIS enclosure to ensure the stable operation of equipment.In this paper,the vibration characteristics simulation analysis of of enclosure under the fault of discon-nector and insulating spacer of GIS is performed,and the simulation models in case of healthy insulatign spacer bu weak contact of disconnector contact,and in case of normal disconnector but cracked insulating spacer are set up.The vibration acceleration of the disconnector with different contact states and the modal frequency and mode of the insulating spacer with different crack depth are calculated by finite element simulation software.The research shows that after occurrence contact defect of disconnector,the smaller the contact area of the contact,the higher the cur-rent applied to the conductor,the higher the vibration acceleration of the disconnector.In case of crack of the insulat-ing spacer,the modal frequency of GIS enclosure is decreased gradually with the increase of crack depth.Therefore,the above results show that it is feasible to analyze the operating state of GIS equipment under the two fault types by using the vibration characteristics of the enclosure.关键词
