1.電(diàn)氣接(jiē)點(diǎn)測(cè)溫的(dí)必要性

電力(lì)係統的(dí)一次(cì)係(xì)統(tǒng)一(yī)般由供電(diàn)綫(xiàn)路（包(bāo)括架空綫(xiàn)路和(hé)電纜(lǎn)），變壓器(qì)，母綫，開關櫃等電氣(qì)設(shè)備組(zǔ)成。其相(xiāng)互之間(jiān)存在(zài)大(dà)量的電氣連接(jiē)點(diǎn)，由(yóu)於電(diàn)流(liú)流過(guò)產生熱(rè)量，所(suǒ)以幾乎(hū)所有的(dí)電氣(qì)故(gù)障(zhàng)都會導致(zhì)故(gù)障點溫度的變(biàn)化。例如架空(kōng)綫(xiàn)路搭(dā)接(jiē)點(diǎn)，電纜(lǎn)接(jiē)頭(tóu)，電(diàn)纜(lǎn)中間連(lián)接處，電(diàn)纜敷設(shè)彎折(zhē)處(chǔ)，高壓電纜(lǎn)的局(jú)部(bù)放(fàng)電，高壓開(kāi)關(guān)櫃的(dí)動靜觸頭及其(qí)他(tā)連(lián)接處，低(dī)壓(yā)電(diàn)氣(qì)連接處(chǔ)等位置(zhì)過熱(rè)是(shì)大型事故的征(zhēng)兆,也是(shì)事故多發(fā)的重(zhòng)災區(qū)。

Necessity of temperature measurement at electrical contacts

The primary system of a power system is generally composed of power supply lines(including overhead lines and cables), transformers, busbars, switchgear and other electrical equipment. There are a large number of electrical connection points between them, and almost all electrical faults will cause the temperature change of the fault point due to the current flowing through it and generating heat. For example, overheating is a sign of large accidents and a major disaster area, such as overhead line connection, cable joint, cable middle connection, cable laying bend, partial discharge of high-voltage cable, dynamic and static contact of high-voltage switch cabinet and other connections, and low-voltage electrical connection.

2.當(dāng)前(qián)現狀

多年來(lái)，由於技術水平的(dí)限(xiàn)製，雖然曾利用(yòng)紅外測溫儀，紅外成像儀(yí)，感溫電(diàn)纜(lǎn)，傳統的(dí)點式測溫(wēn)係統希望解(jiě)決上(shàng)述問題，但(dàn)都(dū)無法實現開關櫃內如(rú)斷路器，刀(dāo)閘聯(lián)接點和觸(chù)頭測溫(wēn)。目(mù)前，國內電(diàn)力測溫(wēn)主(zhǔ)要應用(yòng)紅外點測儀(yí)和光(guāng)纖測溫(wēn)儀(yí)，而(ér)在綫方(fāng)式(shì)由於無(wú)法解(jiě)決(jué)高壓絕緣問題，所以高壓開(kāi)關的觸(chù)點等空間(jiān)有限(xiàn)的電(diàn)氣設(shè)備基(jī)本上都是處於(yú)無監控的狀(zhuàng)態下(xià)運行(háng)，存在重(zhòng)大(dà)安全隱患。

Current Status

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.

3.項(xiàng)目(mù)背(bèi)景信息(xī) Project background information

國(guó)內一家專業提供工業+AI 解(jiě)決方案(àn)的公司，從埃及(jí)當(dāng)地一(yī)家成(chéng)套(tào)廠了解到，他(tā)們有個房建(jiàn)項(xiàng)目，配電(diàn)間開關櫃需要安裝無綫(xiàn)測(cè)溫(wēn)產品。該(gāi)公司(sī)從網上找到(dào)了安科瑞，目前先做一(yī)套演示櫃(guì)，測量櫃內電(diàn)氣節點溫度，由(yóu)於沒(méi)有啟動電(diàn)流，選擇(zé)我司帶(dài)電池無(wú)綫測溫傳(chuán)感(gǎn)器ATE200二(èr)代，搭(dā)配接收器ATC450-C，並(bìng)且(qiě)在(zài)櫃(guì)子上做一個本(běn)地(dì)顯(xiǎn)示。

Project background information

A domestic company specializing in industrial and AI solutions learned from a electrical complete plant in Egypt that they had a building construction project recently. The switchgear in the distribution room needs to be installed with wireless temperature measurement products. The company has found Acrel from the Internet. At present, they first need to make a set of demonstration cabinet to measure the temperature of the electric contact in the cabinet. Since there is no starting current, we will choose the second generation of wireless temperature sensor battery powered ATE200, with receiver ATC450-C, and make a local display on the cabinet.

    近(jìn)年(nián)來(lái)，無綫測溫產(chǎn)品開(kāi)始出(chū)現。內置(zhì)電(diàn)池(chí)和無(wú)綫(xiàn)發(fā)射模塊的測溫(wēn)傳感器安(ān)裝於各測(cè)溫點，由(yóu)於(yú)體(tǐ)積小，且無(wú)需(xū)任何接(jiē)綫(xiàn)，其電氣安(ān)全性得到保(bǎo)證。傳感(gǎn)器周期性的(dí)將(jiāng)測溫(wēn)數(shù)據(jù)無綫發送(sòng)至接收單元，接(jiē)收單(dān)元(yuán)發(fā)送數據(jù)至接(jiē)收(shōu)單(dān)元。

    對配電間(jiān)內電氣設備(bèi)的(dí)溫(wēn)度檢測(cè)，采用集中接(jiē)收和顯(xiǎn)示的方案(àn)，大(dà)量(liáng)減(jiǎn)少工程安裝工作(zuò)量，縮短安裝(zhuāng)時(shí)間，使得重要(yào)變(biàn)電站(zhàn)的測溫(wēn)改(gǎi)造得(dé)以方便實(shí)現(xiàn)，對(duì)於新(xīn)站的(dí)建(jiàn)設也具有(yǒu)同樣的(dí)優(yōu)勢。

    無綫(xiàn)測(cè)溫產品(pǐn)滿(mǎn)足了變(biàn)電站開關(guān)櫃節點的(dí)實時(shí)測溫(wēn)的需求(qiú)，在(zài)減少投資，減(jiǎn)少工(gōng)程(chéng)安裝(zhuāng)量，減少維護人(rén)工和費用方(fāng)麵(miàn)優(yōu)勢明(míng)顯。實施(shī)本項(xiàng)目，能夠(gòu)合(hé)理(lǐ)提(tí)升供(gōng)電(diàn)係統(tǒng)的(dí)安(ān)全可靠(kào)運行水平(píng)，減少停(tíng)電故障，對(duì)於保(bǎo)證正常生(shēng)產，減(jiǎn)少(shǎo)事故造(zào)成的損失具(jù)有重大意義(yì)。

Advantages of wireless temperature measurement products

In recent years, wireless temperature measurement products began to appear. The temperature sensor with built-in battery and wireless transmitter module is installed at each temperature measuring point. Due to its small size and no wiring, its electrical safety is guaranteed. The sensor periodically sends the temperature data wirelessly to the receiving unit, which sends the data to the receiving unit.

For the temperature detection of electrical equipment in the distribution room, the scheme of centralized reception and display is adopted, which greatly reduces the engineering installation workload and shortens the installation time, making it convenient to realize the temperature measurement transformation of important substation, and also has the same advantage for the construction of new stations.

Wireless temperature measurement products meet the demand of real-time temperature measurement at switch cabinet contacts in the distribution room, and have obvious advantages in reducing investment, engineering installation, maintenance labor and cost. The implementation of this project can effectively improve the safe and reliable operation level of the power supply system and reduce power failure, which is of great significance to ensure the normal production and reduce the loss caused by accidents.
