摘要
为检测锡盟—山东特高压输变电工程锡林郭勒盟1000kV特高压变电站1100kVGIS(气体绝缘开关设备)安装后主回路的绝缘性能,现场进行了主回路绝缘试验。由于GIS设备电容量较大,为保证试验频率达到工频要求,将设备分两段进行耐压试验。试验包括老练试验、交流耐压试验和局部放电检测,最高试验电压达到1100kV。该项试验一次性零缺陷通过,试验经验可为后续特高压变电站现场耐压试验提供技术支持。
The main circuit insulation test was carried out to detect the insulation performance of the main circuit of the 1100 kV GIS (Gas Insulated Switchgear) after the GIS was installed in Xilin Gol 1000 kV UHV substation. To ensure the frequency meeting the requirements of power frequency caused by the large capacity of GIS equipment, the equipment was divided into two sections to carry out the experiment. The test included sophisticated test, AC voltage test and partial discharge test. The maximum test voltage was 1100 kV. The test was completed on the first try with zero defects, which could provide technical support for the following AC voltage test in the UHV substations.
