产品介绍

用途

本系列中间继电器用于各种保护和自动控制装置中,以增加保护和控制回路的触点数量和触点容量。

型号

 

结构和原理

本继电器的接触系统由几种带顶杆的触点簧片灵活地组装成多种触点形式,但根据传统需要情况DZYDZLDZJ只取12种触点形式,而DZBDZSDZK型又只取12种中常用的几种触点形式。因为触点是装在导磁体两侧,为了作用力均匀与造型美观便将两侧触点对称布置,因此本继电器触点组的变化都是成对的增减。

虽然在规定的寿命以内继电器的触点不必更换,但考虑继电器的使用时间实际是尽可能长的,并且运输、安装、使用中都可能发生意外情况使继电器损坏,在本继电器中相对于其它零部件来比,触点片还是比较容易损坏的,因此将它列为易损件,标明图号,以便使用单位采用。

根据继电保护用的中间继电器常与信号继电器同时使用的情况,本继电器X型产品附有联动的动作信号指示与复归机构,并附有一对带机械保持的动合触点以接通远方信号。即完全可以将联用的信号继电器省掉。这对提高保护装置的可靠性,简化接线,降低成本是有一定意义的。

本继电器采用一个专用船形支架,其尾部固定底座,中间装设继电器机构。不但拆装灵活,而且去掉底座、外壳,继电器仍自成一体,在特殊需要时可无底无壳供货。
