GIS在城市电网中得到广泛的应用,目前由于此类 设备的结构和接线方式上的特殊性,传统的检测方法很 难监督其运行状况,常规的SF6气体的检测方法仅检测 气体湿度,无法判断设备内部是否存在潜伏性故障。 SF6气体在设备正常的运行情况下均含有一定量杂质, 当设备内部存在故障时,在电弧或高温的作用下,SF6气 ...
SF6N2混合气体应用于GIS设备的研究
SF6gas decreases with the increase of micro-water content; when the gas pressure is set to 0.4~0.6 MPa, the micro-water content is more than 800 μL/L, and the frequency breakdown voltage of SF6gas decreases more...
This article discusses the GIS in the operation of the gas water pressure, SF6 purity and the administrative measures, and to easy SF6 gas leakage reasons and positions of the measures should be taken and carry on the detailed analysis. Keywords: GIS; SF6 gas; Operation management 中图分类号...
