The application of this technique in high speed circuit breaker can solve the key technique, and can acquire the good result. 将这种技术应用快速断路器的设计中,基本解决了快速断路器结构设计中的关键技术,取得良好的效果。
With short working hours and high action speed, the activity of dynamic iron core and the instantaneous swicth of coil current would generate eddy current in the dynamic and static iron core when the permanent magnetic actuator of vacuum circuit breaker was working. 真空断路器永磁机构工作时间短、动作速度快,动铁芯的运动和线圈电流的瞬时通断会在动静铁芯中产生涡流。
