Abstract

A multigaps gas switch (MGS) with corona discharge for voltage balance is developed. The self-breakdown characteristics of the switch under different gas pressures and the volt-ampere characteristics of corona discharge are studied. The experiment results show that to increase the shot times can improve the self-breakdown voltage stability of the switch. After conditioning the switch self-breakdown voltage relative standard deviation is less than 2%, the voltage balance has a good effect; the volt-ampere characteristics of multigaps corona discharge is similar to single gap. The delay time and jitter of the MGS with corona discharge for voltage balance in different conditions have been tested. The trigger stability is fine when switch charging at ±100 kV.
