　　五、热继电器的选用热继电器的保护对象是电动机，故选用时应了解电动机的技术性能、启动情况、负载性质以及电动机允许过载能力等。（1）长期工作的电动机，可按电动机的额定电流选用热继电器。取热继电器整定电流的0.95～1.05倍或中间值等于电动机额定电流。　　总断路器（漏电断路器）下一级的各个负载回路也是按各个回路的负载容量并留有适当的余量来选择匹配各个回路负载容量载流量的导线，之后就是按照各个负载回路的导线来匹配相应脱扣电流值的断路器或漏电断路器来保护导线才能保障。

　　1.计算电流互感器变比:设电流互感器变比为K.则：变比K=额定一次电流/额定二次电流（例如：100/5A的电流互感器的变比K=100/5=20）2.测量值的计算：设电流互感器二次电流为A2...已知电流互感器变比（倍率）为K，测得二次电流为I2。　　电位移矢量D与有介质时的高斯定理介电常数高斯定理是建立在库仑定律的基础上的，在有电介质存在时，它也成立，只不过计算总电场的电通量时，应计及高斯面内所包含的自由电荷q0和极化电荷q'：（1）前面我们推导过下列公。

　　玻璃板液位计方便操作人员观察。液位联锁触发且无法复位，机组无法启动A套冷冻机突然停车，故障显示液位高高。操作人员马上重新启动机组，无法启动。随后切换启动备机，也无法启动，液位高高一直存在，但液位显示20%左右，怎么会高高。　　采用万用表检测扬声器也是粗略的。测量直流电阻：用R*1档测量扬声器两引脚之间的直流电阻，正常时应比铭牌扬声器阻抗略小。例如8欧姆的扬声器测量的电阻正常为7欧姆左右。测量阻值为无穷大，或远大于它的标称阻抗值，说明扬声器已经损坏。

　　为什么蓝纸在低压钠灯照射下变黑了呢。要弄清这个问题，首先要对日光做一番分析。原来日光是由红、橙、黄、绿、青、蓝、紫等多种颜色的光按照一定的比例混合而成的。日光照某一颜色的物体（指非体）上，物体将其他颜色的光吸收，而将这种颜色的光反来。
