摘要
总结了SF6开关设备气体渗漏的特点、现场表现及原因;讨论了解体除漏与带压堵漏的风险决策问题;介绍了泡沫法、定性检漏仪报警检漏法、包扎加定量检漏仪检漏法、激光成像检漏仪检漏法等常用检漏方法;阐述了检漏方法选择的观点;对带压堵漏进行了理论计算,介绍了几种漏点消除方法;最后介绍了几次现场检漏与漏点处理的典型案例。得出定性检漏仪和泡沫检漏法结合使用,操作简单,能提高检漏效率和成功率。
This article summarized the SF6 switchgear gas leakage characteristics, the on-site performance and the reason; discussed the venture decision questions： the disintegration to eliminate leaks and the stoppage leaks with pressure; introduced the froth law, qualitative leak detector alarm leak detection law, the wrap add the quota leak detector leak detection law, the laser image formation leak detector law and so on the commonly used leak detection method; elaborated the leak detection method choice viewpoint; carried on the theoretical calculation of the stoppage leaks with pressure, introduced several leaking point elimination method; finally introduced several scene leak detection and the leaking point processing illustrative case.
