一种新型电气化铁道交流高压真空断路器

【摘要】 本文介绍一种新型电气化铁道专用真空断路器,它采用双稳态永磁机构作为执行操作单元,电子控制器作为控制单元。机械元件大量减少,从而提高了断路器的可靠性,可达到免维护、少维修,为铁路跨越式发展及高速、重载提供有力的设备保证。更多还原

【Abstract】 The article introduces a new type of vacuum circuit breaker special for electric railways, which has adopted bistable permanent magnet mechanism as operational unit, electronic controller as control unit. It reduces dramatically the mechanical component, improves the reliability of circuit breaker, realizes the maintenance-free and less repair of it and guarantees the reliability of equipment for rapid development, raise of running speed and heavy transportation of railways.更多还原
