摘要

500 kV晋陵变220 kV GIS设备发生SF6泄漏问题

为确保设备安全运行和可靠供电

经多方协作

对泄漏的GIS设备进行了漏气消缺工作:先由厂方人员对漏气气室进行检修（一个月后

厂家与用户对GIS泄露原因进行了联合调查）;后由中试所人员对检修部分进行基于LC谐振原理的耐压试验;耐压试验通过后

对停役的GIS设备恢复运行。最后介绍了该次220 kV GISⅠ、Ⅱ母停役检修对区域电网造成的不利影响。

Abstract

To remove SF6 leakage of a 220 kV GIS in 500 kV Jinling substation

the damaged GIS was overhauled by the manufacturer.One month later

the manufacturer and the user investigated the cause of leakage together.Then

a voltage-withstand test based on LC resonance over-voltage principle was conducted by Jiangsu EPRI.After the test

the out-service GIS was returned to operation.The adverse influence on the local gird is discussed during the out-service period of bus Ⅰ and Ⅱ in Jinling substation.
