摘要：隨著電力工業(yè)的發(fā)展，對設(shè)備的安全性、可靠性要求越來越高。在這種條件下，高壓設(shè)備的無線測溫系統(tǒng)應(yīng)運而生。這種技術(shù)是將內(nèi)置電池或電流感應(yīng)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
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。

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.
This article introduce wireless monitoring system used in substations in Netherlands.
1.當(dāng)前現(xiàn)狀 Current Status
多年來，由于技術(shù)水平的限制，雖然曾利用紅外測溫儀、紅外成像儀、感溫電纜、傳統(tǒng)的點式測溫系統(tǒng)希望解決上述問題，但都無法實現(xiàn)開關(guān)柜內(nèi)如斷路器、刀閘聯(lián)接點和觸頭測溫。目前，國內(nèi)電力測溫主要應(yīng)用紅外點測儀和光纖測溫儀，而在線方式由于無法解決高壓絕緣問題，所以高壓開關(guān)的觸點等空間有限的電氣設(shè)備基本上都是處于完全無監(jiān)控的狀態(tài)下運行，存在重大安全隱患。
For many years, due to the limitations of the technical level, although infrared thermometer, infrared imager, temperature sensing cable, traditional point-type temperature measurement system have been used to solve the above problems, but can not achieve the switch cabinet such as circuit breaker, the connection point and contact temperature measurement. At present, domestic electric temperature measurement mainly uses infrared point measuring instrument and optical fiber temperature measuring instrument. However, the on-line method cannot solve the problem of high-voltage insulation, so the electrical equipment with limited space, such as the contact of high-voltage switch, basically operates in a completely unmonitored state, with major safety hazards.
