摘要：隨著電力工業(yè)的發(fā)展，對設備的安全性、可靠性要求越來越高。在這種條件下，高壓設備的無線測溫系統(tǒng)應運而生。這種技術是將內置電池或電流感應和無線發(fā)射模塊的測溫傳感器安裝于各測溫點，由于其體積小，且無需任何接線，其電氣安全性可以得到保證。傳感器周期性的將測溫數(shù)據(jù)無線發(fā)送至接收單元，接收單元可聯(lián)網(wǎng)將數(shù)據(jù)送至主站，以此實現(xiàn)一個區(qū)域系統(tǒng)的電氣溫度監(jiān)測。
本文介紹了無線測溫傳感器在南非的應用
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.
