ABB A,AF,AL系列接触器 AF*24-60V DC
接法:
Answer:
一:一般三相接触器一共有16个点，三路输入，三路输出，两组常开辅助触头，两组常闭辅助触头，还有是控制点两个（接触器线圈）。输出和输入是对应的，很容易能看出来。如果要加自锁的话，则需要从常开辅助触头将线接到控制点上面。
One: the general three-phase contactor has 16 points, three way input, three output, two sets of normally open auxiliary contacts, two groups of normally closed auxiliary contacts, and two control points (contactor coil). The output and input are corresponding, and can be easily seen. If you want to lock yourself, you need to open the auxiliary contact to the control point.
二: 首先应该知道交流接触器的原理。他是用外界电源来加在线圈上，产生电磁场。加电吸合，断电后接触点就断开。知道原理后，你应该弄清楚外加电源的接点，也就是线圈的两个接点，一般在接触器的下部，并且各在一边。其他的几路输入和输出一般在上部，一看就知道。还要注意外加电源的电压是多少（220V或 380V），一般都标得有。并且注意接触点是常闭还是常开。如果有自锁控制，根据原理理一下线路就可以了。
Two: first of all, we should know the principle of the AC contactor. He is using an external power source to add an online circle to produce an electromagnetic field. When the power is added, the contact point is disconnected after the power is broken. When you know the principle, you should find out the contact point of the external power supply, that is, the two contact points of the coil, generally in the lower part of the contactor and on one side. The other ways of input and output are generally in the upper part, and you can see it at the same time. Also pay attention to the voltage of the external power supply (220V or 380V), generally standard. And notice whether the contact points are often closed or often open. If there is self-locking control, the line can be rationed according to the principle.
