Description

一种基于机械H桥的双稳态磁保持继电器 技术领域
本发明涉及一种磁保持继电器，具体涉及一种基于机械H桥的双稳态磁保持继电器。
背景技术
传统的继电器在使用中需要的是持续的电流，只要不断电，继电器就能持续工作。这中间就存在一个取电的问题，通常的做法是让继电器与一电池或者所属机构的自身电源连接。这种继电器的能耗相对较高，不仅提高了用电成本，而且违背了政府所倡导的构建资源节约型社会的要求，不利于我国的可持续发展。
如今，一种由永磁铁和单线圈(或双线圈)构成的磁保持继电器已经获得了广泛应用。这种磁保持继电器是通过对线圈释放脉冲电流而触发的，其好处就是只有当触发时才会耗电，一旦进入一个状态后，磁保持继电器就不需要能量了，相比于传统继电器大大节省了能源。但这种磁保持继电器也存在一些缺点，比如线圈往往会发热，而且这种磁保持继电器的触发也比较复杂，都需要通过MCU进行管理，最节能的MCU也会消耗电能，对于孤立能源体并不适用，并存在无电失控风险，一定程度上降低了可靠性，同时增加了生产成本。

本发明的工作原理如下：
当本发明的磁保持继电器需要由导通稳态转换到断开稳态时，第二MOS管控制线圈激励电源给予第二线圈电磁铁的励磁线圈一个脉冲激励电流，使得第二线圈电磁铁产生磁力，吸引磁性接触开关向右侧(第二线圈电磁铁的方向)移动；然后磁性接触开关继而带动连杆一同向右移动，连杆的一端则拉动衔铁弹片，使得动触点与静触点分离，第一衔铁和第二衔铁断开，即磁保持继电器处于断开状态；同时，随着连杆的右移，连杆的另一端则带动双向选择开关中的金属弹片的活动端从第二连接点摆动到第一连接点，使得第二线圈电磁铁的励磁线圈断开，第一线圈电磁铁的励磁线圈接通，等待下一次稳态转换。从第二稳态转换到第一稳态时，工作原理则与之相反。
与现有技术相比，本发明的有益效果是：
1、本发明巧妙地将第一线圈电磁铁、第二线圈电磁铁、双向选择开关和磁性接触开关构建成了一个机械H桥。第一线圈电磁铁和第二线圈电磁铁可通过相互轮流导通或断开来控制磁性接触开关在这两者之间的转相换位，从而实现本发明的磁保持继电器可以处于闭合和断开这两个不同的稳态。磁性接触开关则可通过带动连杆一方面来控制金属弹片的活动端在双向选择开关中第一连接点与第二连接点之间的来回切换，另一方面来控制动触点与静触点的贴合与分离。
2、本实用新型的结构紧凑，安全可靠，使用寿命长，除了触发激励用电外没有其他多余能耗，大大节约了能源，应用范围广，特别适合孤立能量单元的管理。
3、本实用新型属于瞬间激励，不需要过多考虑电路的承载能力和线圈的过载能力，在使用中线圈不会出现发热现象，从根本上杜绝了传统磁保持继电器存在的线圈发热问题。
