BOYM-3H电能表现场校验仪是集电参量测量、电能表校验、接线判断为一体的高精度测试仪器。该仪器配以高精度、高线性度的电压互感器和电流互感器，使仪器对各种参量的测量精度很高，同时配有钳形电流互感器，使得现场接线简便，无需断开电流回路即可直接接入。

不同型号和容量的电度表其计度器窗口位数不同，是否接互感器也不同，故最后一个数字走到多少是一度电也不同。在具体计算时可参见如下其中与最后一个数字实际电量有关的部分：首先抄读电度表，方法是:表上黑窗口中的数字表示整数，红窗口中的数字表示小数，中间用点隔开。抄读时先看黑窗口中整数，再看红窗口中的小数。(要注意不同型号.容量的电度表其计度器窗口位数不同。)再计算电量：电量数

(本次抄见数-上次抄见数)*倍率而电度表倍率一般分两部分：一是由电度表本身结构决定的倍率，也称电度表本身倍率，它等于电度表的齿轮比(电度表计度器末位字轮转一周所需铝盘转数)/电度表常数(电度表每千瓦时的铝盘转数)。电度表本身倍率有可能为1。二是电度表经互感器接入时的倍率，即电流互感器的变比.电压互感器的变比。当低压不需接入电压互感器时，则不计该项。故当电度表直接测量时：电度表倍率

电度表齿轮比/电度表常数。当电度表经电流互感器.电压互感器接入时：电度表倍率

由梦人 07-22 11:01

电流互感器变比*电压互感器变比*电度表齿轮比/电度表常数。另外，现今还有三相电子式多功能电能表安装使用，它的读取还有所不同

深拥你入怀 07-22 11:09

是10KV/24KVSafeSF6柜吗地进地出电缆室里的互感器为的是接电操(绿色弹簧蓄能机构上那电机)或微动开关(透明绿色那个!)用这些东西的出线号和互感器的进线号是对应的!互感器两种型号(一种大的一种小的,一个单元三互感器,看你的什么厂出的了)最好能拿二次系统图看,肯定有.如果你是终端用户,实在不会,那就叫ABB的客服了.如果你是二道手(见谅)就找你们厂的技术(出二次图的人)
