This paper presented a new dynamic PMA applied in vacuum circuit breaker.This machine was unsymmetrical
bi-static
multi-coiling
multi-core PMA.Compared with the traditional PMA
it had an optimized magnetic path configuration
and could make well use of high magnetism energy provided by PM.This was propitious to improve the initial speed in the opening process and performance of bounce.Moreover
lower power energy was consumed in the opening-operation and closing-operation.Analysis of the Static magnetic field on the novel dynamic PMA was completed in the paper.
