摘要
结合无源型高压直流转换开关的工作原理,分析、计算了避雷器的工况。对其关键技术保护水平和能量释放能力进行了深入研究,提出了高压直流转换开关避雷器残压测量冲击电流波形(波前时间不小于250μs)的依据和ZnO电阻片极限能量释放能力选取值,对实际工程中的高压直流转换开关用避雷器的设计具有指导意义。
Operating condition of surge arrester was analyzed and calculated according to operating principle of passive high voltage direct current （HVDC） transfer switch. Key technologies of surge arrester such as protection level and energy release ability were researched in depth. The basis of current impulse waveform（front time of impulse is not less than 250p.s） of residual voltage measurement of surge arrester for HVDC transfer switch and the selected value of ultimate energy release ability of ZnO varistors were suggested. These conclusions play an instructive role in the design of surge arrester for HVDC transfer switch in the actual construction.
