摘　　要：为验证干式空心并联电抗器投切过电压受破坏问题,提出了干式空心并联电抗器投切过电压测量方案,并组建了测量系统。对某220 kV变电站一组66 kV干式空心并联电抗器进行了三次投切过电压现场测试,测量结果表明投切干式空心并联电抗器能够产生较高过电压,同时对现有仿真理论计算进行了真型验证,搭建测量系统时要解决分布参数对测量的影响问题。In order to verify the damage of switching overvoltage of dry-type air-core shunt reactor,the switching overvoltage measurement scheme of dry-type air-core shunt reactor is proposed,and the measurement system is established.A group of 66 kV dry-type air core shunt reactors in a 220 kV substation are tested for switching overvoltage for three times.The measurement results show that switching dry-type air-core shunt reactors can produce high overvoltage,and the existing simulation theoretical calculation is verified.The influence of distributed parameters on measurement should be solved when building the measurement system.
