真空断路器操动机构选型比较分析

Analysis on the Operating Machine of the Vacuum Circuit-breaker

真空断路器以其优良的机械寿命与电寿命、少维护等特点,在中压开关领域独领风骚.从机械寿命、分合闸特性、操作电源、智能化等方面对电磁机构、弹簧机构、永磁机构等操动机构进行比较分析,确定永磁机构应为真空断路器首选机构.

Vacuum circuit-breaker is prominent in the area of the middle-voltage switch because of its longer machine and galvanic life and fewer preservation. Comparing the operation machine of the electromagnetic machine, the spring machine and the everlasting-magnet machine with the machine life,close-trip characteristic, operating power and artificial intelligence, we can conclude that everlasting-magnetmachine should be the best machine of the vacuum circuit-breaker.
