Study And Analysis Of Dynamic Characteristics On New Operating Mechanisms Of Vacuum-Breaker

The dynamic characteristics of the magnetic operating mechanisms is decided by the match of the electromagnetic force and the counterforce.In the past,the cooperation of the static electromagnetic force and the counterforce is emphasized in the design of operating mechanisms and the electromagnetic force is bigger than the counterforce in the all process under the operation voltage.So it often happened that make up the circuit-breaker and the life of the circuit-breaker is shorten because the non-matching.The closing velocity of contact must meet the demands of the two sides:one is that from the point of minishing the impact and vibration the velocity should be small; the other is that from the point of security of closing process the velocity should be large.To solve the above questions,we must study the dynamic characteristics of operating mechanisms.This paper study a new kind magnetic operating mechanisms designed by my director prof.Cui Yanbin and analysized the structure and the principle,especialy in large space formulates the dynamic characteristics of the operating mechanisms.
