 Application of Acrel Wireless Temperature Measuring Product in Substation in Netherlands

摘要：隨(suí)著電力(lì)工業的發展，對(duì)設(shè)備的安(ān)全(quán)性(xìng)，可(kě)靠(kào)性(xìng)要求越(yuè)來(lái)越(yuè)高。在這(zhè)種條件下，高壓設(shè)備(bèi)的(dí)無(wú)綫測溫係(xì)統(tǒng)應運而(ér)生。這種(zhǒng)技術(shù)是將內(nèi)置(zhì)電池或(huò)電流(liú)感應和(hé)無綫(xiàn)發射(shè)模(mó)塊的測(cè)溫傳(chuán)感器安裝於(yú)各測溫點(diǎn)，由於其體積小，且(qiě)無需任何接綫(xiàn)，其(qí)電(diàn)氣安全性(xìng)可以得(dé)到保(bǎo)證。傳感器周(zhōu)期性的將測溫數(shù)據無綫發(fā)送至接(jiē)收(shōu)單(dān)元，接收單元可聯網將(jiāng)數據(jù)送至主(zhǔ)站(zhàn)，以(yǐ)此實現一個(gè)區(qū)域(yù)係統的(dí)電(diàn)氣溫度(dù)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.當前(qián)現(xiàn)狀 Current Status

多年來，由(yóu)於技術(shù)水平的(dí)限(xiàn)製(zhì)，雖然(rán)曾利用紅外(wài)測溫(wēn)儀(yí)，紅外成像儀(yí)，感溫(wēn)電纜，傳(chuán)統的(dí)點式(shì)測(cè)溫係統(tǒng)希望(wàng)解(jiě)決(jué)上述(shù)問題(tí)，但都無法實現開關(guān)櫃內如斷(duàn)路(lù)器，刀(dāo)閘聯接點和觸(chù)頭測(cè)溫。目前(qián)，國內電力測溫主要應用紅外點測儀(yí)和(hé)光纖(xiān)測溫儀(yí)，而在綫(xiàn)方式由於(yú)無法解(jiě)決(jué)高壓絕緣(yuán)問(wèn)題，所(suǒ)以高壓(yā)開關(guān)的觸(chù)點等空間有限的電氣設備基本上都(dū)是(shì)處於無(wú)監(jiān)控(kòng)的(dí)狀態下(xià)運行，存在(zài)重大(dà)安全(quán)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.
