【摘要】 介绍了国内永磁操动机构的发展状况,并分析了影响其发展的主要因素。据不完全统计,2002年国内配永磁操动机构的断路器产品的销售总量只有约1000台。因此促进永磁操动机构的推广与应用应从其整体出发,兼顾机构本体和机构控制部分(包括电源)的性能与成本,提高其整体的技术经济指标。更多还原

【Abstract】 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.更多还原
