摘　　要：讨论新型选相操作智能控制器的控制单元组成及其工作原理,通过对控制过程的多环节改进,实现对真空断路器永磁操作机构的精准控制,从而减小变压器在空载合闸并网过程中产生的励磁涌流。The constitution and working principle of the control unit of the intelligent controller for the phase selection of the new-type vacuum circuit breaker are discussed. The accurate control of the permanent magnetic operating mechanism of the vacuum circuit breaker is realized by improving several links in the control process, in order to reduce the magnetizing inrush current produced by the transformer in the process of no-load closing and synchronizing.
