摘要
结合我国±800kV高压直流输电工程的内过电压研究结果和交、直流避雷器的额定参数推荐值,对±800kV高压直流输电工程的绝缘配合进行分析研究,提出该工程交、直流设备的雷电冲击绝缘水平和操作冲击绝缘水平的推荐值。对换流站的雷电过电压保护和直流线路的防雷保护进行研究,提出防雷保护的建议。
The insulation coordination for the ±800 kV DC power transmission project was studied, combined with the results of the internal over-voltage calculation and the rated parameters of the AC and DC arresters of the ±800 kV DC power transmission project in China. The lightning over-voltage protection of the converter station and the lightning protection for the lines were studied, and the suggestions of the lightning protection were proposed.
