三相电表可以承受多大的功率和怎么选互感器倍数
三相电表功率主要是看三相电表的电流规格和现场电压来决定的,如果是直流式电表,功率P=I电流*U电压*3,下面我们就一起来看看三相电表可以承受多大的功率和怎么选互感器倍数.
一、三相电表可以承受多大的功率
三相电表电流规格是40A,现场电压是380V,那么功率P=40A*380V*3=45600W,为什么要乘以一个3呢,因为这是三相电表,40A*380V只是一个相线的功率,所以三相功率必须要乘以3,三相直入式电表最多可以做到100A,所以直入式的电表最大功率只可以承受114000W的功率,如果比这个功率还要高的话,直入式的三相电表就不能满足需要了哦,我们需要用到互感式电表.
二、怎么选互感器倍数
互感式电表就不限制功率,只要互感器的倍数达到,随便多少功率都是可以的,比如我们要测量20万W的功率怎么办呢,一般互感器式的电流规格是1.5(6)A,我们可以先计算出电流,I=P/U=200000W/380V≈53A,那么我们再用互感器将电流变成电表测量范围内的电流,互感式的电表电流范围一般是1.5到6A,把电流变成5A的话,就要用到10倍的互感器,所以测量20万的功率,只要用10倍的互感器就行了.
以上就是三相电表可以承受多大的功率和怎么选互感器倍数,希望对你有所帮助如果你还有别的问题的话也可以联系我们.
