摘要:
为抑制真空开关分闸、合闸操作引起的暂态影响,分析了真空开关分闸、合闸时的受力情况及对其操动精度的影响因素,仿真计算了永磁机构的动态特性;设计了一个自适应操动机构控制系统对真空开关操动机构的励磁电流、机构行程实时监测,通过驱动IGBT有序控制操动机构电容放电,有效修正其动作分散性:增加系统电压、电流相位检测单元后可实现设定相位准确动作.测试结果证明,控制系统可以明显降低真空开关操动机构的动作分散性,且操动机构分闸、合闸动作分散性控制在±500 μs以内.
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.
