YOU Yi-min, CHEN De-gui, HOU Jiang-xin, et al. DEVELOPMENT AND APPLICATION OF PERMANENT MAGNETIC ACTUATOR[J]. High voltageapparatus, 2003, (6): 54-56.DOI:
This paper introduces the current situation of permanent magnetic actuator used in China. The main factor of impeding the wide application of permanent magnetic actuator is analysed. According to the incomplete statistics
the sales quantity of the vacuum circuit breaker mounted with permanent magnetic actuator is only about 1000 units in 2002. In order to promote the application of the actuator
complete design including the actuator itself and related control unit as well as their costs should be considered.
