1 000 kV特高压GIL气室SO₂超标异常原因分析及改进措施

Dianci bileiqi
本研究对一起1 000 kV特高压气体绝缘金属封闭输电线路（GIL）气室SO2超标展开分析。提出现场加压辅助定位方法进行诊断，对异常部位增加X光检测，发现C相气室4垂直段插接触头有疑似脱出部件和疑似点状凸起。现场解体检查发现母触头触指、压环及不锈钢挡圈从正常位置脱出，触指与公触头熔合。提出返厂模拟挡圈拉力测试，发现拉力达到116.5 kN时，挡圈从母触头处脱出。得出母触头内不锈钢挡圈未安装到位，运行中逐渐脱出后，导致触指与母触头接触不良，长期运行电流作用下母触头与触指过热烧蚀引起SF6气体分解 ...
