主变高压侧GIS SF6气体泄漏分析

Reasons for Gas Leakage of GIS SF6 on High Pressure Side of Main Transformer

GIS具有占地面积小、损耗低、运行较为稳定的优点,现已被广泛应用于电力系统中。在GIS气室中常应用SF6为绝缘介质,但在长时间的使用期间内,常出现SF6气体泄漏问题。本文首先阐述了主变高压侧GIS中SF6气体泄漏的危害以及气体泄漏的原因,并简单介绍了检测与处理SF6气体泄漏的方法,为提高主变高压侧GIS运行的安全性与稳定性提供参考。

GIS has the advantages of small area,low loss and stable operation.SF6 is often used as insulating medium in GIS chamber.But during a long period of use,SF6 gas leakage often occurs.In this paper,the hazards of SF6 gas leakage in high-pressure side GIS of main transformer and the causes of gas leakage are described.The method of detecting and treating SF6 gas leakage is introduced briefly.To improve the security and stability of the main transformer high-voltage side GIS operation.
