电能表的结构和作用有哪些?

Release date: View count:451

 

  电的使用是人类文明的一大进步。在生活中,文明处处需要用电。而对电使用计量的工具,就是电能表。下面小编来介绍一下电能表的结构和作用有哪些?

  一、电能计量装置的概念

  电能表也叫电度表,是电能计量装置的核心,是计量负载消耗的或电源发出的电能。

  电能计量装置:是由电能表、互感器(电流互感器、电压互感器)、电能表到互感器的二次回路三部分组成。

  电能表的结构和作用有哪些?

       二、各部分的作用分别为:

  电能表型号:1位D-电能表;2位表示相线:D-单相、S-三相三线有功、T-三相四线有功;D-多功能

  电能表铭牌:以创力电表DTS7281D型为例,220V表示额定电压,1.5(6)A表示额定电流为1.5A,最大电流为6A,50HZ表示额定频率,1600ipm/kw.h表示计1600个脉冲为一度电。

  以上就是本篇文章的全部内容,如果您想要了解更多关于电能表的相关知识,请关注本网站!
