摘　　要：气体绝缘组合电器母线(GIB)是气体绝缘金属封闭开关设备(GIS)中不可缺少的组成部分,具有汇集、分配和传送电能的作用。主要针对河南某220 kV变电站GIB母线支架基础异常开裂情况进行了原因排查,以ZF28A-145型为模型,仿真分析了母线柔性支架的设置原则,验证柔性支架补偿的合理性,并提出相关改进建议,为今后同类型GIB母线工程提供参考。GIBs are an indispensable part of gas- insulated metal- enclosed switchgear （GIS） and have the function of collecting, distributing and transmitting electrical energy. In this paper, mainly fi）r a 220 kV substation in Henan GIB busbar support base of the abnormal cracking of the cause of the situatiml to ZF28A - 145 as a model, simulation analysis of the principle of bus- bar flexible support to verify the flexibility of the flexible support compensation, and put tbrward the relevant Suggestions for improvement, provide reference tor the same type of GIB busbar project in the future.
