| 摘 要： | 针对某GIS变电站110 kV交联聚乙烯电缆出线A相挂有一相线路TV,该TV无法与带电体脱开进行交联聚乙烯电缆耐压试验且试验装置容量不够的情况进行了理论分析.提出并论证了一种切实可行的解决办法--升高频率进行串联谐振耐压,该法有效解决了此类由设备特殊结构造成的无法试验的问题.

| Abstract: | This paper introduces a theoretical analysis and practical solution about a GIS substation with 110 kV XLPE cable,in which an electromagnetic voltage transformer(EVT) is installed.Due to the non-disassembly EVT,a practical voltage withstand test method,series-parallel resonant with increasing frequency,is suggested.The results show that it is an effective solution. |

| Keywords: | non-disassembly overexcite magnetic saturation frequency series resonance voltage withstand test |
