| 摘 要： | 气体绝缘金属封闭输电线路(gas insulated line,GIL)在我国输电系统中占有越来越重的比例,推广使用直流GIL对于完善现有直流输电方式具有很强的经济效益。与交流GIL相比,直流GIL研究的技术难点和差异主要在于绝缘方面。研究直流GIL绝缘问题能够指导其运行维护并对其进行寿命预测。文中从直流GIL整体绝缘设计和GIL内部局部放电检测两个方面,梳理和介绍了国内外对交直流GIL各方面的研究情况,为针对直流GIL绝缘问题的后续研究提供了参考和借鉴。

| Abstract: | Gas insulated line (GIL) occupies an increasing proportion in the transmission system. The promotion of DC GIL can improve the existing DC transmission mode, and has a very strong economic benefits. Compared with AC GIL, the major technical difficulties and differences of DC GIL are insulation issues. Studies on DC GIL insulation issues are helpful to its operation, maintenance, and life prediction.Domestic and foreign researches on DC GIL are widely introduced from two aspects: the overall insulation design and internal partial discharge detection. It can provide a better cognition and reference for further study on DC GIL insulation problems. |
