配永磁机构真空断路器运动特性控制技术的研究

Investigation on the Controlling Techniques of Moving Contact Behaviors for Vacuum Circuit Breaker with Permanent Magnetic Actuator

真空断路器的动触头运动特性对其开断能力和寿命影响很大。介绍了一种控制分闸运动特性的方法,通过控制永磁机构的分、合闸线圈的接入时间,控制分闸的的运动特性。在实验室进行了试验,验证了该方法的可行性。

The moving contact travel behavior influenced the interrupting capacity of a circuit breaker. This paper presents a new modified method to control the operating characteristic for permanent magnet （PM） type circuit breaker. The travel curve of moving contact can be controlled by controlling the current in open and close coil. The result of laboratory tests and the availability are presented.
