但断路器增大了,在电路中没有同时开启所有电器,而是只开启了一个电器的时候,虽然电器过载,但电流依旧没有达到断路器的额定电流,也就不会跳闸、起不到保护作用。且2.5平方电线的载流量,国标下行规定为16A(数据来源《GB/T4706.1-2005》),也就是说,载流量为16A的电线,就允许出售。在220V电路中,3520W功率的电器,产生的电流就会超过16A。如果将3000W以上的电器放在一个回路内,干路电流势必过载。

以变压器接线方式Y/△11为例,讲解星转角(Y△)问题:1.1为了便于理解本文假设:变压器高低压侧额定电流均为1A;变压器平衡系数为1;从相量图我们可以看到两侧电流之间会出现30的相位差,那怎么干掉这30°的相位差呢?当然是要通过保护装置的软件算法对相位进行校正。微机型保护装置有2种相位校正方式:三角形侧向星形侧校正(△Y)和星形侧向三角形侧校正(Y△)。版权所有。我国广泛采用的是星形侧向三角形侧校正(Y△)方式,所以本文也只讲解星形侧向三角形侧校正(Y△)这种方式。
