AONE/A-ONE AUTOVALVE,AD40-20S1参考价　　用数字万用表欧姆档2K以下档测量线圈，看线圈是否断路,如果断路证明线圈坏。用万用表欧姆档200测量常闭和常开（测量常开用手按住或者通电吸住）辅助触点通不通，如果触点不好，此时测量电阻是很大的。表明触点不好，如果辅助触点接有负载，测量电压时，电压会达不到额定电压。　　上图,是双电容单相电动机接线盒上的接线图，图上清晰的反映了电动机主绕组、副绕组和电容的接线位置，你只需要按图接进电源线，用连接片连接Z2和U2，UI和VI，电动机顺转，用连接片连接Z2和U1，U2和VI，电动机逆转。用万用表也容易区分6根线，阻值的是启动绕组，阻值比较小的运行绕组，阻值为零的是离心开关。
　　⑶电压互感器使用注意事项①电压互感器的二次绕组不允许短路。因为一旦发生短路，二次绕组将产生一个很大的电流，导致一次绕组电流随之激增，由此将烧坏互感器的绕组。②电压互感器的二次绕组应当可靠接地。③电压互感器的二次绕组阻抗不得小于规定值，以减小误差。

　　根据磁场转速n1=60f/p的公式，n1下降，转子转速也随之下降，使风量减小，散热不良，又会导致电机温度上升。要使60HZ的电动机用于50HZ的电源上不，可采用降低电源电压的方法来解决。以380伏电动机为例说明。
