一起750kV变电站GIS支柱绝缘子故障分析
Case Study of a Insulator Fault in 750kVGIS substation
:Together 750kV GIS insulators fault, through faulty equipment to test, inspect and analyze the reasons for the decomposition of defects. GIS internal insulators found the existence of small bubbles, resulting in the operation of an internal insulator discharge, resulting in the breakdown insulator flashover. And proposed treatment methods and precautions to avoid such failures occur again.
