Description

一种永磁保持器
本实用新型属合闸同步异位双吸合双稳态，永磁、电磁一体化的开关机构。适用于电力系统高低压开关领域，也适用于机械运动装置控制领域。
传统的高低压开关靠弹簧储能释放能量或电磁能量做功，需要大量的机械零部件，结构繁锁，零部件故障率高。
本实用新型包括有永磁体闭合定磁轭组件，T形动铁芯部件，合分闸线圈组件，磁分路紧急分闸部件。其特征在于永磁体闭合定磁轭组件，T形动铁芯部件，合分闸线圈组件，磁分路紧急分闸部件组成的合闸同步异位双吸合双稳态，永磁、电磁一体化结构。
附图(1)为本实用新型的剖面结构原理图。由图(1)可以看出，本实用新型的实施例包括有永磁体闭合磁轭组件(1)，永磁体与内外定磁轭组成为一体并内设有动铁芯与导向杆组装制做的部件(2)，合分闸线圈组件(3)固定在永磁体闭合磁轭组件(1)的上空腔内，磁分路紧急分闸部件(4)置放于永磁体闭合磁轭组件(1)的下空腔内并通过导出杆在外部进行机械锁扣。
本实用新型实施例的工作过程是：电动分闸时，施加给合分闸线圈组件(3)中的分闸线圈单元一个反向直流或脉冲电流，T形动铁芯部件(2)产生电磁力，克服合闸永磁保持力脱扣向下运动到终端吸合锁扣。电动合闸时，施加给合分闸线圈组件(3)中的合闸线圈单元一个正向直流或脉冲电流，T形动铁芯部件(2)克服分闸永磁保持力脱扣向上运动到达终端产生强大的保持力吸合锁扣。紧急分闸时，手动打开磁分路部件导杆上的机械锁扣后，磁分路部件靠内部弹簧储备的能量自动向上运动切入永磁体闭合定磁轭的间隙内磁通分流，T形动铁芯两吸合面的永磁力急剧下降实现紧急脱扣分闸。此时T形动铁芯部件(2)连同磁分路部件(4)在外力的作用下运行到终端的同时完成能量储备并实现磁分路部件机械锁扣备用。
