摘　　要：简介了用取消合闸电阻的 330 k V断路器合 32 5 /130 km空载线路时有关过电压和 MOA动作电流的计算和现场试验结果 ,证明了三相合闸过电压的概率符合正态分布 ;给出了各种操作方式下的统计过电压。This paper briefly introduces the calculation results and field test results of overvoltage levels and discharge currents of MOA during energizing or reclosing 325/130 km transmission lines by using 330 kV circuit-breaker without closing resisters. It is proved that the probability of three phases energizing overvoltages is normal distribution function. Statistical overvoltages during various switching conditions and discharge currents of MOA as well as the qualifications to remove closing resisters are given.
