实施例2
在实施例1基础上，本实施例2提供了一种设备待机断电方法，包括：在设备待机时，控制主电路中磁力脱扣开关在待机时切断供电。
所述设备待机断电方法包括控制器；所述控制器适于接入设备供电主电路中，并且控制主电路中磁力脱扣开关在待机时切断供电；其中所述控制器包括：适于连接主电路中控制用次级线圈的整流电路，位于整流电路输出端并联有第一延时电路；以及所述整流电路的输出端还连接一开关电路，并且所述开关电路由第二延时电路控制；当设备通电后，流经控制器的电流为启动电流或工作 电流；此时，所述整流电路得电，对第一延时电路进行充电，并且在第二延时电路延时充电作用下，开关电路截止；即所述第二延时电路获得存储电能。

以下通过具体案例对上述两实施例的实施过程进行详细阐述。
如图1所示，变压器B是串入设备的电源电路中，根据变压器特性，依据交流固态继电器AC-SSR输入电压3～12VDC/20mA的要求构建本控制器。
一般设备正常工作与待机电流有10倍以上变化。变压器B的输出经整流电路，输出直流脉动电流，经稳压管DW限制电压(防止起动大电流造成过压，其将电压限值为7.4V)，给电解电容C1充电，变压器初级线圈导线截面按最大电流设计，因变压器设计输出功率小，可以采用电阻R1降压，以提供后级使用。电阻R1、电解电容C1配比以20K、1μ或10K、2μ等等电路响应为佳。由于电解电容C1、电阻R1能产生数倍电压降，因此，变压器系列可以设置较少规格，如，1A，5A，10A，50A等。
依据交流固态继电器AC-SSR输入电压3～12VDC/20mA的要求，变压器与电解电容C1、电阻R1选择应该使电解电容C2上稳定时的电压为3.6～4V，电解 电容C2容量大于470μ，电阻R2、电解电容C2具有延时作用，其可以将设备起动到稳压这段时间保持本电路不触发，延时时间可以长达十几分钟。
电路工作过程，主电路中控制用次级线圈输出整流电路经电解电容C1、电阻R1，电压快速上升，在电阻R2、电解电容C2延时作用下，PNP型三极管BG1无输出，后续电路不工作。当设备达到设定的设定电流后，电阻R2、电解电容C2延时结束，电解电容C2上电压稳定在3.6～4V，进入待机状态时，变压器B输出电压、电流锐减，电解电容C1上电压开始下降，下降速度由电解电容C1、电阻R1决定，当电解电容C1电压低于电解电容C2并达到PNP型三极管BG1导通阈值时，电解电容C2通过PNP型三极管BG1向交流固态继电器AC-SSR输入端送电。磁力脱扣器脱扣，开关复位，设备及本电路供电电路切断，实现零功耗。
按照不同的功能，(如单相、三相交流电)以及控制电流大小，将执行部分磁力脱扣开关制作成固定模块，根据需要设计配置。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
