摘要

研究GIS外壳的振动特性对于保证设备的稳定运行具有重要意义。文中围绕GIS隔离开关、盆式绝缘子两种故障类型进行外壳振动特性的仿真分析，搭建了盆式绝缘子完好时隔离开关触头接触不良和隔离开关正常时绝缘子含有裂纹时的仿真模型，利用有限元仿真软件计算了接触状态不同时隔离开关的振动加速度以及不同裂纹深度时盆式绝缘子的模态频率与振型。研究表明：隔离开关出现接触缺陷后，触头接触面积越小，对导体施加电流越大，隔离开关的振动加速度就越大。当盆式绝缘子出现裂纹缺陷时，GIS外壳模态频率随着裂纹深度的不断增大而逐渐下降。因此，综合以上结果表明了利用外壳的振动特性分析两种故障类型下GIS设备的运行状态具有可行性。

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 disconnector 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 current applied to the conductor

the higher the vibration acceleration of the disconnector. In case of crack of the insulating 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.
