- Abstract:
- o decrease the transient influence caused by the switching operation of vacuum switches,the resultant force on vacuum switch in the operating period and the influence factors on operating accuracy were analyzed in this paper.Dynamic characteristics of permanent magnetic actuator in the operating processes were calculated.A self-adaptive control system for actuator,which could real-time control the excitation current and travel agency of actuator,was designed.The control system could modify action dispersion of the actuator effectively by driving IGBT to control the discharging orders of capacitors.It could also realize accurate operating at setting voltage and current phases by adding phase detection unit.Test results of the control system showed that the control system could reduce the action dispersion of vacuum switch actuator significantly,and the action dispersion was controlled within ± 500 μs.
