GIS局放耦合器密封性现场检测及气体泄漏允许值的探讨

Discussion on In-situ Gas Leakage Detection and Allowed Leakage Value of GIS PD Coupler

鉴于局放耦合器部位SF6气体泄漏量的大小直接影响GIS设备的长期安全稳定运行,介绍了某电站局放耦合器现场气体检漏检测方法及泄漏量允许值的计算方法,提出了制定精确规范的局放耦合器现场检漏方法以及泄漏量允许值标准的建议。

The amount of SF6 gas leakage from the partial and stable operation of the gas insulated substation （GIS） PD coupler hydropower tion method discharge （PD） coupler will directly affect the long-term safe equipment. Thus, an in-situ leakage detection method for the and a calculation method of the allowed leakage station. It is also recommended to establish and allowed leakage value. value are introduced, which are successfully accurate and standardized criteria on the SF6 gas 1 adopted in a eakage detec-
