摘要
为了适应直流输变电工程蓬勃发展的需求,中国高压开关制造企业应自主研发并生产直流开关设备,以用国产化的直流开关装备中国的直流输电工程。笔者简要说明了中国直流输电的发展及直流场设备的基本情况,详细介绍了低压侧50 kV直流隔离开关的技术性能及参数要求、通流能力及传动设计分析与计算及直流绝缘子选择等内容,以期对直流开关的研发设计有所启示和帮助。
It is necessary for Chinese HV switchgears manufacturers to research and develop DC switchgears independently to meet the requirements of the rapid development of DC transmission and transformation projects in China.This paper described the development of DC transmission and the basic information of DC field equipment in China,with the emphases on the low-voltage-side 50 kV DC disconnector＇s technical performance,parameters,current flux,and transmission design and calculation,as well as selection of DC insulators in order to benefit the development and design of the DC switchgears in China.
