| 摘 要： | 介绍了国外特高压避雷器的发展和运行情况,对前苏联、瑞典、德国及日本等国家研究和开发特高压避雷器的主要技术参数、结构及性能进行了分析。阐述了中国避雷器发展的状况,分析了中国已经研制的750kV系统用避雷器技术性能,提出了准备开发的1000kV避雷器的技术参数和建议。为了降低系统的绝缘水平,应开发1000kV的敞开式电站保护用避雷器、GIS电站保护用避雷器及线路保护用避雷器。避雷器的额定电压为828kV,雷电冲击保护水平为1620kV。并指出中国在现有的基础上能够开发出1000kV避雷器。

| Abstract: | The worldwide development of UHV surge arresters,service and measures to restrict over-voltages at UHV transmission lines are described.The main technical parameters,construction and performance of UHV surge arresters developed in former Soviet Union,Sweden,Germany and Japan are analyzed.yDevelopment of surge arresters in China is presented.iMain technical parameters of 750 kV MOA developed in China are analyzed.iRecommendations and main technical parameters for development of 1 000 kV MOA are put forward.iTo lower insulation level of system,1 000 kV MOA for protecting open type substation,iGIS substation and transmission lines are recommended.Rated voltage of 1 000 kV MOA is 828 kV,ylightning impulse residual voltage of 1 000 kV MOA is 1 620 kV.yIt is pointed out that based on existing facilities,development of 1 000 kV MOA in China is possible. |
