ACREL Wireless Temperature Sensor Application in South Africa

摘要：随着电力工业的发展，对设备的安全性、可靠性要求越来越高。在这种条件下，高压设备的无线测温系统应运而生。这种技术是将内置电池或电流感应和无线发射模块的测温传感器安装于各测温点，由于其体积小，且无需任何接线，其电气安全性可以得到保证。传感器周期性的将测温数据无线发送至接收单元，接收单元可联网将数据送至主站，以此实现一个区域系统的电气温度监测。

本文介绍了无线测温传感器在南非的应用

Abstract：With the development power industry,the requirements for the safety and reliability of equipment are getting higher and higher.In this situation,ACREL wireless temperature monitoring system is designed for high voltage device.This technology is to install the temperature sensor with built-in battery or temperature sensor by current sensing and wireless transmitter module at each temperature measurement point. The sensor periodically sends the temperature measurement data wireless to the receiving unit, and the receiving unit can be connected to the network to send the data to the master station, thereby realizing electrical temperature monitoring of a regional system.
