高压真空断路器的一种新的永磁操作机构结构设计

A Novel Structure Design of Permanent Magnetic Actuator Used in High Voltage Vacuum Circuit Breaker

提出了分闸侧采用盆型结构的四线圈双稳态永磁操作机构结构概念,并为这种永磁操作机构设计了控制回路,使永磁操作机构能为高电压等级真空断路器提供更好的分、合闸驱动特性,以充分发挥真空灭弧室高寿命、高可靠性的优点。

This paper presents a novel structure of four coil double steady state permanent magnetic actuator which opening side is basin shape, and its control circuit is given. Theoretical analysis indicates that, with this basin shape structure, four coil double steady state permanent magnetic actuator can drive high voltage vacuum circuit breaker more suitably, and the excellences of long life and high reliability of vacuum interrupter can be brought into full play.
