摘要
根据试验参数和现场的试验条件,北川110 kV智能变电站的GIS现场耐压试验选择了调频串联谐振耐压装置。耐压试验结果表明,北川变电站GIS无明显绝缘缺陷,但在设计上存在GIS气室结构不合理、互感器和避雷器布置不规范等缺陷。为了减少这些缺陷给试验带来的影响,提出了一些弥补措施和建议。
According to the test parameters and test conditions,FM series resonant withstand voltage device is chosen for on-site withstand voltage tests of GIS in 110 kV Beichuan Smart Substation.The experimental results show that none of the obvious insulation defects exist in GIS.However,there still have the design defects,such as unreasonable structure of gas room,irregular layout of surge arrester and potential transformer etc.Some remedial measures are proposed to reduce the influence of these defects on the tests.
