Description

高压直流继电器磁路系统
技术领域
[0001] 本发明涉及一种高压直流继电器， 具体涉及一种高压直流继电器磁路系统。
背景技术
[0002] 高压直流继电器是通过磁路系统使动铁芯和固定在动铁芯上的推动杆上下移动 ， 从而使固定在推动杆顶端的动触点上下移动以与静触点接触或分离。 磁路系 统所产生的磁力线密度沿动铁芯向上运动的方向逐渐减小， 因此， 动铁芯在磁 路系统磁力的作用向上移动吋， 动铁芯越是运动到靠近轭铁板的位置， 动铁芯 所受磁路系统磁力的作用力越小， 即动铁芯自下而上向上运动吋所受到的推力 会越来越小。 如果动铁芯所受到的来自磁路系统的磁力作用力过小， 则会导致 动铁芯和推动杆上升距离不够， 使得动触点无法与静触点接触， 或动触点与静 触点接触不良。 为保证磁路系统在动铁芯向上运动的整个行程中都具备足够磁 力以驱动动铁芯移动， 现有技术的做法是增加磁路系统线圈的功率， 即增加线 圈的匝数， 这样会导致继电器体积增大、 制造成本升高。
技术问题
[0003] 本发明的目的是提供一种可增加磁路系统在动铁芯运动的整个行程中对动铁芯 磁力作用力的均匀性、 能保证动触点与静触点良好接触， 且不会增加继电器体 积和生产成本的高压直流继电器磁路系统。

， 使动铁芯在整个运动行程中都能受到基本相同的磁力作用力， 可在保证动铁 芯和推动杆受到较为均匀的磁力作用力的情况下上升以使动触点与静触点接触 ， 而无须额外增大线圈的功率， 降低了本发明继电器的功耗， 并可减少线圈的 匝数， 将线包做小， 从而可降低线圈架、 下导磁筒、 U形轭铁的高度， 以减小本 发明继电器的体积， 以降低生产成本。

[0011] 作为优选， 所述线圈架上端形成有向内凸出的内凸环， 所述动铁芯上端形成向 外凸出的外凸环， 所述外凸环位于所述内凸环的上方。
[0012] 作为优选， 所述上导磁筒的内径大于所述外凸环的外径。
[0013] 作为优选， 所述凹槽上下贯穿所述轭铁板， 所述上导磁筒凸起的高度大于所述 凹槽的深度。 上述设置可使凸起的上缘位于轭铁板， 便于凸起与轭铁板间的固 定作业。
[0014] 作为优选， 所述凸起位于轭铁板上方的部位即为铆点处， 所述凸点铆压后形成 的铆压块盖覆在所述轭铁板上表面。 铆点处位于轭铁板上侧， 可便于上导磁筒 与轭铁板铆接或焊接作业的进行； 铆压块盖覆在轭铁板上表面， 可避免上导磁 筒向下脱离轭铁板。
