1.背景(jǐng)信息(xī) Background：

隨(suí)著電力(lì)工(gōng)業(yè)的發展，對(duì)設(shè)備(bèi)的安(ān)全(quán)性(xìng)，可靠性要(yào)求(qiú)越(yuè)來越高
。以(yǐ)往(wǎng)人工(gōng)巡視設備的方(fāng)法已逐(zhú)漸弱(ruò)化(huà)，在這種條件(jiàn)下(xià)，高壓設備(bèi)的無(wú)綫測溫(wēn)係(xì)統應運而生
。這(zhè)種技(jì)術是(shì)將(jiāng)內(nèi)置(zhì)電(diàn)池和無綫(xiàn)發射模(mó)塊的測(cè)溫傳(chuán)感器(qì)安裝(zhuāng)於各(gè)測(cè)溫點，由於其(qí)體積小，且(qiě)無(wú)需(xū)任何接綫(xiàn)，其電氣(qì)安(ān)全性可(kě)以得(dé)到保(bǎo)證(zhèng)
。傳(chuán)感(gǎn)器(qì)周期性的將測溫(wēn)數據無綫發送至(zhì)接(jiē)收單元(yuán)，接收單元(yuán)可(kě)聯網將(jiāng)數據(jù)送(sòng)至(zhì)主(zhǔ)站，以此實現一個區域係統(tǒng)的(dí)電氣溫度監(jiān)測
。
目前(qián)我國(guó)許(xǔ)多(duō)地方的(dí)電網公司，變電(diàn)站，鋼(gāng)鐵(tiě)公司等都(dū)已在(zài)高(gāo)壓設(shè)備上采用(yòng)這種無綫(xiàn)測(cè)溫(wēn)監測技(jì)術(shù)
。

電(diàn)氣(qì)接點(diǎn)在(zài)綫(xiàn)測(cè)溫(wēn)裝(zhuāng)置適用(yòng)於(yú)高低(dī)壓開(kāi)關(guān)櫃內電纜接頭(tóu)，斷路(lù)器(qì)觸(chù)頭，刀(dāo)閘開(kāi)關(guān)，高壓電(diàn)纜(lǎn)中間(jiān)頭，幹(gān)式變壓(yā)器，低壓大(dà)電(diàn)流(liú)等設備(bèi)的溫(wēn)度監測(cè)，防止在運(yùn)行(háng)過(guò)程(chéng)中因氧(yǎng)化，鬆(sōng)動，灰塵等因(yīn)素(sù)造(zào)成(chéng)接點(diǎn)接(jiē)觸電阻過大(dà)而發(fā)熱(rè)成為安全隱患，提(tí)高設備安全保(bǎo)障，及時(shí)，持(chí)續(xù)，準確(què)反映(yìng)設備運行狀(zhuàng)態(tài)，降(jiàng)低(dī)設(shè)備(bèi)事故(gù)率
。

With the development of power industry, the safety and reliability of equipment are highly demanding. In the past, the method of manual inspection equipment has been gradually weakened, under this condition, the wireless temperature measurement system of high voltage equipment came into being. This technology is to install the temperature sensor with built-in battery and wireless transmitting module at each temperature measuring point. Because of its small size and no connection, its electrical safety can be guaranteed. The sensor periodically sends the temperature measurement data wirelessly to the receiver, and it can send the data to the main station on a network, so as to realize the electrical temperature monitoring of a regional system.

Currently, many power grid companies, substations and steel companies in China have adopted this wireless temperature monitoring technology on high voltage equipment.

The electric terminal on-line temperature measuring device is using for the temperature monitoring of cable connector, circuit breaker contact, knife switch, high voltage cable intermediate head, dry transformer, low voltage high current and other equipment in high and low voltage switch gear.To prevent excessive contact resistance caused by oxidation, loosening, dust and other factors during operation, heating becomes a hidden danger of safety, to improve the safety and security of equipment, to reflect the running state of equipment in time, continuously and accurately, and to reduce the accident rate of equipment.
