摘要
论述了涡流对真空灭弧室触头开断能力的影响,以及涡流产生的原因,并加以证明,表明了触头体在交变磁场中将产生感应涡流,使触头磁场滞后于电流,影响触头开断能力;要使触头达到理想设计,应将触头涡流减到最小。
The paper describes the influence on current breaking capability of vacuum interrupter contact by eddy current theoretically.And the cause of forming eddy current is analyzed.It presents the experiments and analyses to prove the conclusion as following： contact body will form eddy current in alternating magnetic field,that lead to magnetic field of contact lags behind current.It will affect the capability of contact current breaking.Eddy current of contact should be minimized even to zero to get the ideal design of contact body.
