不同负载下接触器的选用

日期：2025-06-19 06:02

浏览次数：477

摘要：

为了使接触器不会发生触头粘连烧蚀，延长接触器寿命，接触器要躲过负载启动*大电流，还要考虑到启动时间的长短等不利因数，因此要对接触器通断运行的负载进行分析，根据负载电气特点和此电力系统的实际情况，对不同的负载启停电流进行计算校合。

控制电热设备用交流接触器的选用

这类设备有电阻炉、调温设备等，其电热元件负载中用的绕线电阻元件，接通电流可达额定电流的1.4倍，如果考虑到电源电压升高等，电流还会变大。此类负载的电流波动范围很小，按使用类别属于AC-1，操作也不频繁，选用接触器时只要按照接触器的额定工作电流Ith等于或大于电热设备的工作电流1.2倍即可。

照明设备的种类很多，不同类型的照明设备、启动电流和启动时间也不一样。

此类负载使用类别为AC-5a或AC-5b.如果启动时间很短，可选择其发热电流Ith等于照明设备工作电流1.1倍。启动时间较长以及功率因数较低，可选择其发热电流Ith比照明设备工作电流大一些。

不同照明设备用接触器选用原则。
