双位置继电器DLS-5/2 DC220V
双位置继电器,顾名思义就是指该继电器具有两个位置,同时在两个位置上均能自保持。实际上,双位置继电器是含有两个线圈的磁保持继电器。
线圈A得电后,继电器触点动作,即使其失电,触点也不返回;线圈B得电后,继电器触点返回,即使其失电,触点也不会再动作。也就是说,若使双位置继电器触点位置翻转,必须有一个线圈带电。
双位置继电器在变电站二次回路中较为常见,多用于对状态保持、可靠性要求较高的回路中。如双母接线的电压切换回路以及电压并列回路。
双位置继电器的两个线圈分别接对方的辅助触点,例如线圈I要串接线圈II的辅助触点,线圈II要串接线圈I的辅助触点,这样一来线圈不会长时间带电工作,其次线圈可以保持在I位或II位。
