摘要
为了更优地利用空间,保障安全,节省维护成本,35 kV及以上配电系统多采用GIS气体绝缘金属封闭开关设备,为了保障投运的可靠性,避免造成电气事故,其中相序相位的调整准确尤为重要。文章针对35 kV及以上设备核相问题,结合现场配电柜情况进行了梳理和分析,从而进一步提高了线路核相的准确性。
With the continuous development and progress of society,enterprises have higher and higher requirements for automation,intelligence,industrialization and large-scale,and the power demand and voltage level of related power distribution equipment are also higher and higher,in order to make better use of space,ensure safety and save maintenance cost,Gis gas-insulated metal-enclosed switchgear is often used in power distribution systems of 35 kV and above,it is very important to adjust the phase sequence and phase accurately.In this paper,the problem of phase check for 35 kV and above equipments is analyzed and sorted out,so as to improve the accuracy of line phase check.
