The analysis of electrodynamics force based on outdoor post-mounted vacuum circuit breaker

LIN Xin YAN Hongkui ZHANG Hao (College of Electrical Engineering,Shen Yang University of Technology,Shen Yang 110023,China)  
There are many reasons that the outdoor post-mounted vacuum circuit breaker dose not work well.The influence of electrodynamics force is reason for that.Great electrodynamics force is produced by short-circuit current.With analysis of electrodynamics force about three-phase short-circuit current,after stress analysis,the appearance of short huge electrodynamics force influence outdoor post-mounted vacuum circuit breaker greatly.Having proposed improving the scheme to avoid the influence to vacuum circuit breaker on the outdoor post-mounted of electrodynamics force maximally and reduce the trouble incidence of vacuum circuit breaker efficiently.
