摘要
对750kV GIS耐压及局部放电、超声波探伤试验进行了介绍,针对这两个现场特交试验中出现的问题进行分析,提出意见与建议,有助于后续750kV工程特交试验的顺利进行,保证设备可安全投入电网运行。
Based on the test methods of 750 kV GIS field withstand voltage test coupling with partial discharge measurement and defect detection of porcelain supporting insulator, the paper analyses the problems which were found in the test and gave some suggestions for resolving these problems. The results which were made in the paper are useful for the hand-over test of 750 kV equipment, guarantee the equipments to be safe before operating in the power system.
