ABB中间继电器的工作原理是通过金属电路的改变，来改变电路的电流分布，使得电路中的电流按照预定的方式流动。

它的作用是将一个发出的信号转换成另一个信号，从而起到控制和保护电路的作用。

继电器和接触器的区别是什么？2016-06-12继电器和接触器都是电磁式开关电器，但前者属于工作在控制回路中的开关电器，而后者属于工作在主回路中的开关电器。

我们先看两者的共同特征：第一个概念，叫做转换深度：式中的叫做断开或者截止时的电阻，叫做接通或者导通时的电阻，h叫做转换深度对于有触点的开关电器，；对于无触点的电器，。

正是由于有触点的开关电器，它的转换深度比较高，从而保证在接通电路时，开关电器的执行电流电能损耗小，对被控电路的影响也小；断开电路时，有触点的开关电器，其执行电路ide电阻非常高，从而可以保证电器的耐压水平。

相比之下，无触点电器在开断后，它不会产生电弧。

但无触点电器的转换深度比较低，因此其损耗较大，且发热相对要严重得多。

第二个概念，关于电磁式电器的结构电磁式电器的结构包括触头部件、操动系统和线圈等部件，还有灭弧系统及部件。

电磁式电器分为三类，有电压继电器、电流继电器和其它专门功能的继电器（例如温度继电器、时间继电器和热继电器等等）。

接触器也具有这些结构特征。

简单描述：（1）当电磁式继电器的激磁线圈通电后，激磁线圈电流逐渐增加并在电磁系统中产生磁通，其中衔铁与铁心之间气隙中的磁通将作用于衔铁。

随着工作磁通逐渐增加，作用于衔铁上的电磁吸力（转矩）也越来越大。

当电磁吸力大于系统反力时，衔铁将绕其转动轴转动带动其执行部分（触头系统）的动触头C0运动，从而实现常开触头和常闭触头变位。

（2）激磁线圈断电后，激磁线圈电流逐渐减小，电磁系统中的磁通也逐渐降低，工作气隙磁通也随之降低，作用于衔铁上的电磁吸力越来越小。

当电磁吸力小于衔铁反力时，衔铁在系统反力的作用下开始向其初始位置返回，带动动触点C0向其初始位置运动，直至常开触点和常闭触头复位。

第三个概念，叫做电磁式电器的返回特性返回系数是电磁式继电器共同具有的特性，它反应了电器的继电特性明显程度。

通常返回系数小于1。

将继电器的激磁线圈输入端X看成是元件的输入，将触头系统中触点的变位Y 看成是元件的输出，则继电器输入—输出特性就包括返回系数。
