气体绝缘金属封闭组合电器漏气缺陷及预防措施

Leakage Defects and Preventive Measures of Gas-insulated Metal-enclosed Switchgear

气体绝缘金属封闭组合电器(GIS)具有诸多应用优势,但是漏气问题直接影响其整体绝缘性能。针对气体绝缘金属封闭组合电器漏气问题,本文比较了有效的检漏方法,分析了常见的漏气部位及漏气原因,最后提出了相应的预防措施。

Gas-insulated metal-enclosed switchgear(GIS)has many application advantages,but the problem of air leakage directly affects its overall insulation performance.Aiming at the leakage of gas-insulated metal-enclosed switchgear,this paper compares effective leak detection methods,analyzes common leak locations and causes,and finally proposes corresponding preventive measures.
