　　:磁场的定义磁场是一种看不见、摸不着的特殊物质，磁场不是由原子或分子组成的，但磁场是客观存在的。磁场是对放入其中的磁体有磁力的作用的物质叫做磁场，磁场的基本特征是能对其中的运动电荷施加作，即通电导体在磁场中受到磁场的作。

韩国光星KTD-881T,KTD-891T,KTD-862T,参数产品　　图3c是三相同时过载时的情况，三相双金属片同时向左弯曲，推动下导板2向左移动，通过杠杆5使常闭触点立即引计。图3d是C相断线的情况，这时C相双金属片逐渐冷却降温，端部向右移动，推动上导板1向右移。而另外两相双金属片温度上升，端部向左弯曲，推动下导板2继续向左移动。　　器和空气断路器的配合要根据空气断路器的过载系数和短路保护电流系数来决定。器的约定电流应小于空气断路器的过载电流，器的接通、断开电流应小于断路器的短路保护电流，这样断路器才能保护器。实际中器在一个电压等级下约定电流和额定工作电流比值在1～1.38之间，而断路器的反时限过载系数参数比较多，不同类型断路器不一样，所以两者间配合很难有一个标准，不能形成配合表，需要实际核算。
　　4.注意事项1.测量三相异步电动机绝缘电阻时，不允许设备带电时用兆欧表测绝缘电阻；测量完毕，应对设备进行放电，否则容易引起触电事故。2.兆欧表未停止转动之前，禁止用手触及设备的测量部分或兆欧表接线柱。拆线时，也不可触及引线的裸漏部分。

　　串级系统参照这个执行。这个所谓的趋势读定法，其实早就被广大的自动人员所掌握，只是有些人的思考还不够深入，方法还不够。这里我把它总结起来，大家一起思考。提前声明；这些物理意义的分析，非常简单，非常容易掌握，但是你必须要把下面一些推导结论的描述弄熟弄透，然后才能够进行参数整定。
