中性点 三相电源或三相负载连接成星形时出现的一个公共点。当三相星形连接负载的中性点 N与供电系统的中线连在一起时,中性点N的电位因受到电源的直接约束而与电源的中性点 n的电位基本相同。但若三相星形连接负载的中性点N不与供电系统的中线相连,此时若负载不对称,便会出现所谓中性点位移现象。中性点位移是指在位形图上中性点N和中性点n不再重合,实际上是表明二者的电位不同,出现了电压(此时选中性点n的电位为零),如图1所示。 三相三线制的不对称电路中的电源可以是星形连接,也可以是三角形连接,但二者可以等效互换。为了分析方便,多选用星形连接的三相电源(图2)。取电源中性点n为参考节点,用节点电压法可求出负载中性点N的电压为式中妧а、妧b、妧c是电源的相电压,ZA、ZB、Zc分别是负载 A相、B相和C相的复数阻抗。由求得的又可求出负载的各相电压各相负载电流则为由于负载中性点电压妧x不为零,造成了三相负载电压不对称,有的相会远远低于电源相电压,有的却又大大超过电源相电压,结果造成各相负载难以正常运行。为了避免这种现象出现,在实际的低压配电系统中都加有中线,并且规定在中线上不得串接熔断器和开关,甚至还要用机械强度较高的导线作为中线。
