前段时间有位朋友在我公司做了一会,正好有位顾客过来买三相电表,本来他想帮我的。随知后来他拿了一台单相电表递给顾客。顾客因为是比较着急,就拿着这位朋友递给他的电表急急忙忙就回去了。但是,随后我就接到了一个投诉,说你们的店员连单相电表和三相电表都分不清楚吗?此处省略一千字...当我得知事情后,我也没有去怪我的朋友,我就趁着这件事情,正好教下我的朋友分清单相电表和三相电表的区别。
我对朋友讲,现在市面上的电表就是单相电表和三相电表,单相电表只可以接一根火线和一根零线,可以提供交流220V的电源。而三相四线智能电表能够接零线和三根火线,不仅能够提供三组交流220V的电源,并且还能够提供交流380V的工业级的用电电源。
单相电表的区别:
他们两者的工作原理是一样的,只不过是测量元件的数量不同,单相表只有一个220v的测量的元件,三相表有三个220v的测量元件。单相表用于测量单相负载的用电量或三相平衡负载的用电量,三相表用于三相负载用电量的测量。
单相电表一般运用于居民用户或者是出租房用户,三相电表一般运用于中小用户、配电网、工矿企业、公用设施、民用建筑等。

(The principle is the same, except that the number of measuring elements is different. The singlephase meter has only one measuring element of 220v, and the threephase meter has three measuring elements of 220 V.. The singlephase meter is used to measure the power consumption of singlephase load or threephase balanced load, and the threephase meter is used to measure the power consumption of three-phase load.)
三相电表区别:
三相电表一般运用于电流运用比较大的地方,比如工厂、政府大楼、别墅、商铺等。这些用电的需求量比较大,所以三相电表是**的选择。三相电表还可以加互感器使用,所以加互感器的三相电表是没有电流**值的,多大的电流,只要互感器的变比够都是可以的。

(Threephase meters are generally used in places where current is used more, such as factories, government buildings, villas, shops and so on. There is a large demand for electricity, so the threephase meter is the best choice. Threephase meters can also be used with transformers, so there is no maximum current in threephase meters with transformers, and any current can be as long as the transformer ratio is enough.)
