基于嵌入式系统的电力变压器参数监测与处理

Parameters Monitor and Processing of Power Transformer Based on Embedded System

利用精密整流电路和精密放大电路采集变压器电压与电流的数据。用传感器技术和脉冲变送电路将电能转换为脉冲量,由嵌入式系统对这些数据进行处理,完成对电力变压器各种参数及运行状态的监测。用GSM(全球移动通信系统)模块与监控室的PC机进行数据通信。能记录各种关键数据,为管理部门提供真实可靠的技术资料,自动形成各种电力年报、月报分析曲线等管理报表曲线。显著提高变压器的安全性和可靠性,可用在各种变电所的变压器上,抗干扰能力强,功能独特。

Data of voltage and current were collected by precision rectifier circuit and amplifier from the power transformers,and converted electric energy into pulse signal by means of sensor technique and pulse converter circuit.Embedded system processed these data to complete monitoring to power transformer parameters and running state.Then put on data communications between embedded system and PC of monitoring office by global system for mobile communications(GSM) module.It can register all kinds of key data,and ...
