三相电表的规格信号怎么看以及倍率怎么算

  三相电表的规格信号怎么看以及倍率怎么算

  现在的三相电表一般都是在屏幕上面直接看,屏幕上面是有文字提示显示的,三相电表的总度数,上面的文字提醒一般是"正向有功总电量",三相电表一般屏幕旁边都会上翻键和下翻键,可以上下翻开电表里面的数据.接下来我们一起来了解一下三相电表的规格信号怎么看以及倍率怎么算.

  一、三相电表的规格信号怎么看

  第一字母一般就是D:表示电表的意思

  第二个字母就有区别了,S表示三相三线、T表示三相四线,三相三线一般是高压电表

  第三个字母表示有功无功,S表示有功、X表示无功、Z表示智能、S表示电子式

  第四个字母一般表示功能:D表示多功能、Y表示预付费、F表示复费率、I表示载波等

   三相电表的规格信号怎么看以及倍率怎么算

    二、三相电表倍率怎么算

  三相电表一般都是加了互感器式的接入法比较多,直通的会比较少,这个看电表的接口也可以看得出来,一般直通式的三相电表只有6个孔,加入了电流和电压互感器,要再乘以一个电压和电流的互感器.

  实际用电量=电表计量*电流互感器变比*电压互感器变比

  举个例子:要是互感器的倍率是5/1000,那么电流互感器的倍率就是200,如果在三相电表用的总电量是525kwh,实际用电量就是525kwh*200=105000kwh,要是有电压互感器的话,还需要乘以电压互感器的倍率.

  以上就是三相电表的规格信号看法以及倍率算法,希望对你有所帮助如果还有别的问题可以向我们咨询.
