摘　　要：随着超高压、远距离输电线路的建立和发展,合闸空载线路(包括重合闸)过电压比切空线过电压的出现概率更大且更为严重。现阶段,人们重点关注合闸空载线路(包括重合闸)过电压。分析了空载线路合闸过电压的产生机理及相应抑制措施,为实际工程提供理论依据。Recent years,because of the development of extra high voltage and the construction of long distance transmission lines,the of over voltage and the probability arising over voltage of switching of f lines of no-load operation are reduced obviously,so that switching in lines of no-load operation,and so as the reclosing,becomes one of the most typical a nd serious switching surges in the extra a nd ultra high vo1tage g rid,a nd the most important research target.The generation mechanism and corresponding restraining measures of switching over voltage in unloaded line are analyzed.It provides theoretical basis for practical engineering.
