一种基于ARM平台的智能型多功能变压器温度信号变送器

An Intelligent Transformer Temperature Signal Transmitter Based on ARM Platform

目前,变压器等大型充油设备的测温回路中经常出现温度测量不准、温度变送器容易损坏、测温原理及测温回路不统一等问题。文章提出了一种基于ARM平台的智能型温度信号变送器,它能适应现场多种信号类型下的测温回路,并能在显示屏上直观显示输入信号的类型和大小,能适用于现场绝大多数大型充油设备的测温系统,可替代进口昂贵且单一类型的温度变送器,还能为故障定位提供可靠的依据。

At present,in the temperature measurement circuit of large oil filled equipment such as transformer,the temperature measurement is often inaccurate,the temperature transmitter is easy to be damaged,and the temperature measurement principle and temperature measurement circuit are not unified.In this paper,an intelligent temperature signal transmitter based on ARM platform is proposed.It can adapt to the temperature measurement loop of various signal types on site.,and can directly display the type and size of the input signal on the display screen.It can be applied to the temperature measurement system of most large oil filled equipment on site,It can replace the imported expensive and single type temperature transmitter,and provide reliable basis for fault location.
