从原理上看，零线主要用于工作回路，零线所产生的电压等于线阻×工作回路的电流；地线不用于工作回路，只作为保护线。利用大地的 “0”电压，当设备外壳发生漏电，电流会迅速流入大地。零线与接地线在实际应用中不同：零线的对地电位不一定为零，零线的近接地点是在变电所或者供电的变压器处；地线的对地电位为零，使用的电器的近点接地。零线有时候也是会电人的，比如生活中，有时候电炉子不发热了，有的朋友就会以为是断电了，不会有危 vo Motor In Box Free Shipping 1PC NEW For B&R 8LSA25

硅整流发电机的转速变化范围大，而且传动比较大。由于硅整流发电机的转速变化范围大。硅整流发电机的端电压变化规律可以知道，要表征硅整流发电机的特性，应以转速为基础分析空载特性、输出特性和外特性。输出特性输出特性又称负载特性，它是在发电机保持输出电压一定时，发电机的输出电流与转速之间关系。交流发电机的输出特性由负载特性可以看出发电机在不同转速下输出特性，它表明：发电机在较低的空载转速n1时，就能达到额定输出电压值，可知低速充电性能好。

知道了无功补偿是怎么回事，再来分解无功功率补偿电柜的构造就容易了。首先补偿源，就是电容，电容就是一个储存电荷的器件，在充放之间，完成它的补偿作用。其次，智能无功补偿控制仪，它是整个电柜的大脑，可以设置和补偿方式的切换，扮演指挥官角色，遵循着“欠补高切”的原则控制着电容在电网中的投入和切除。版权所有。再次，就是执行器件了，它就是补偿电柜的无功补偿电容接触器，它相当与士兵，按补偿仪的指令或通或断，说白了，它基本原理和普通接触器一样，只是构造和作用上略有不同。
