【技术实现步骤摘要】
单相导轨式费控智能电能表
本专利技术属于电能表
,特别是涉及一种单相导轨式费控智能电能表。
技术介绍
电能表是用来测量电能的仪表,俗称电度表、火表,按用电设备分为单相、三相三线、三相四线电能表。电能表的工作原理是:当把电能表接入被测电路时,电流线圈和电压线圈中就有交变电流流过,这两个交变电流分别在它们的铁芯中产生交变的磁通;交变磁通穿过铝盘,在铝盘中感应出涡流;涡流又在磁场中受到力的作用,从而使铝盘得到转矩(主动力矩)而转动。负载消耗的功率越大,通过电流线圈的电流越大,铝盘中感应出的涡流也越大,使铝盘转动的力矩就越大。铝盘转动时,带动计数器,把所消耗的电能指示出来。但现有电能表存在体积大,精度低以及不方便用电自动化管理等缺点。因此,如何解决上述问题成为本领域人员研究的重点。
