DFSH1521型多用户集中式电能表
DFSH1521型多用户集中式电能表●防窃电●大容量●高性能●远程联网●数码显示泰安市宏达电子有限公司一、简介DFSH1521型多用户组合式电能表是公司研制生产的高科技产品，它采用微电子处理技术和SMT表面焊接及在线测试技术，能将多达36户单相用电和13户三相用电集中检测，逐户循环显示，并可将各户的用电量由红外抄表器采集或通过RS485接口实现计算机联网以及内刷卡售电功能。
传感元件采用了德国V AC真空熔炼公司研制的1J77A型高导磁率微型电流、电压互感器，与锰铜（或康铜）分流元件相比，具有精度高、量程范围宽、自身功耗低、抗干扰能力强等特点。
DFSH1521型多用户组合式电能表可广泛用于居民楼、集体公寓等用电场所，具有体积小、抄表方便和防窃电等功能，是老式机械电能表最理想的替代产品。
二、技术特点及参数1、技术特点（1）电表集中检测和显示，表箱体积小，抄表方便，防止窃电。
（2）高量程10—60A，用户无须因家用电器的增加而更换电表。
（3）实现远程联网，现场抄表。
（4）表壳冲压成形，密封性能好，符合国标GB/T17215—2002。
（5）电路采用三相电源供电。
即使供电线路缺相，也能正常计量。
（6）同时具备近程红外线抄表和远程计算机联网抄表功能。
（7）采用专用接线端子，双螺栓压线，使用更可靠。
（8）采用高精度微型电量互感器，电器隔离效果好，超负载能力强。
（9）整机功耗低，低于一台机械式电能表的功耗（<7V A）。
（10）远控型DFSH多户表具有计算机联网.刷卡带控制断送电功能，解决了电费收取难的问题。
2、技术参数（1）标定电流：10（60A）；（2）工作电压：AC160V~250V（3）精度等级：2.0级；（4）环境温度：—20℃~55℃（5）0.4％Ib; (6)重量：约6kg(7) 总进线端子接线截面积：≤75mm(8) 用户接线端子接线截面积：≤100mm三．型号说明备注；控制型为DFSH 1521型为降低公用零线上的总电流，电能表总进线一般采用三相四线制接线方式，而用户接线方式可分为单相（D）或三相四线(T)。

多用户电表的使用方法
多用户电表的使用方法
多用户电表是一种新型的电表，它可以实时监测多个用户的电量使用
情况，可以帮助用户更加有效、准确地控制电量消耗。
下面就来介绍
一下多用户电表的使用方法。
首先，您需要安装多用户电表。
安装时，需要根据电表说明书安装，
确保电表安装稳固。
安装完成后，您可以使用它检测多个用户的电量
使用情况，并可以进行智能管理。
其次，您可以使用多用户电表进行电量分配。
多用户电表可以进行电
量拆分，可以根据不同用户的用电情况，分配合理的电量，避免某些
用户因用电过多而影响到其他用户的用电。
最后，您可以使用多用户电表进行智能管理。
多用户电表可以对用户
的用电情况进行实时监测，并可以自动根据用户的用电情况调节电量，从而更加有效地控制用电，节省电费。
总的来说，多用户电表的使用方法比较简单，可以有效控制用户的用
电情况，节省电费，是一种非常实用的电表。
