【 摘 要 】

The fully enclosed combined electrical appliance gas insulated substation (GIS) is an important large-scale substation equipment, which has been widely used in power systems. In order to ensure the safe and reliable operation of this equipment, UHV GIS will conduct the text of lightning impulse and power frequency withstand before delivery of this equipment. In this paper, the method of vibration was used to analyze the lightning phenomenon caused by lightning impulse and partial discharge of 1100kV GIS equipment. Put forward the problems that should be paid attention to when installing GIS equipment, in order to provide reference for troubleshooting GIS equipment in the future.
