摘　　要：变电站中被监测的信号大多为高电压的强电信号,不能直接被监控设备直接接收,因此必须进行信息转换。电力系统的远动装置通过TV和TA的转换将强电信号转换为额定值为100V和5A的交流信号,供系统仪表、保护和测量使用。本文介绍了远动装置数据交流采样的原理及数学模型。The signals that are montored in transformer substation are heavy current signals of high voltage. They can not directly be received by the monitoring equipment. Thus ,they must be changed in informotion. The telecontrol equipment of electric system by TV and TA change the heavy current signals into AC signals of ratings being 100V and 5A to supply system meters,protection and measure. The paper presents the principle and mathematical model of data AC sampling of the telecontrol equipment.
