隨著分布式光纖(xian)(xian)傳感技術的(de)(de)發展，利(li)(li)用一(yi)根測(ce)(ce)溫(wen)(wen)光纖(xian)(xian)就可以獲得沿線的(de)(de)溫(wen)(wen)度分布信(xin)息(xi)。測(ce)(ce)溫(wen)(wen)光纖(xian)(xian)溫(wen)(wen)度的(de)(de)測(ce)(ce)量(liang)一(yi)般通過光纖(xian)(xian)內的(de)(de)光信(xin)號(hao)強度或頻(pin)率(lv)信(xin)息(xi)獲得，實(shi)現光信(xin)號(hao)測(ce)(ce)量(liang)的(de)(de)設(she)備(bei)稱為(wei)分布式光纖(xian)(xian)溫(wen)(wen)度測(ce)(ce)量(liang)設(she)備(bei)，基(ji)于光纖(xian)(xian)拉曼散(san)射(she)的(de)(de)溫(wen)(wen)度測(ce)(ce)量(liang)儀、基(ji)于光纖(xian)(xian)布里淵散(san)射(she)的(de)(de)應變和(he)溫(wen)(wen)度測(ce)(ce)量(liang)儀和(he)基(ji)于光纖(xian)(xian)瑞利(li)(li)相干檢測(ce)(ce)的(de)(de)應變和(he)溫(wen)(wen)度測(ce)(ce)量(liang)儀都屬于此類設(she)備(bei)。

分布(bu)式光(guang)纖(xian)溫度(du)(du)傳(chuan)感(gan)(gan)(gan)技(ji)術主要利用了光(guang)學非(fei)線性效應中拉曼(man)散射(she)(she)光(guang)信號(hao)的(de)(de)強度(du)(du)與溫度(du)(du)的(de)(de)相關性，通(tong)過對光(guang)纖(xian)不同位置處激發產生的(de)(de)拉曼(man)散射(she)(she)光(guang)信號(hao)進(jin)行(xing)探測(ce)與強度(du)(du)分析進(jin)而實現光(guang)纖(xian)不同位置處溫度(du)(du)的(de)(de)測(ce)量。分布(bu)式光(guang)纖(xian)溫度(du)(du)傳(chuan)感(gan)(gan)(gan)技(ji)術中的(de)(de)光(guang)纖(xian)即是傳(chuan)感(gan)(gan)(gan)器也是信息傳(chuan)輸媒介，該技(ji)術具有傳(chuan)感(gan)(gan)(gan)器結構靈(ling)活、分布(bu)連續、監測(ce)距(ju)離(li)長、工作溫度(du)(du)高等特(te)點，因此(ci)在消防與火災(zai)預警、油井勘(kan)測(ce)等領域具有廣泛應用前景。

電(dian)(dian)力電(dian)(dian)纜廣泛(fan)應用(yong)于城市地下電(dian)(dian)網(wang)、鐵路電(dian)(dian)網(wang)、工礦企業內部供電(dian)(dian)及水(shui)下電(dian)(dian)力輸送線路；隨(sui)著電(dian)(dian)力電(dian)(dian)纜應用(yong)領域(yu)的(de)不斷拓展(zhan)，電(dian)(dian)力電(dian)(dian)纜的(de)敷設環境也變得更加復雜，電(dian)(dian)力電(dian)(dian)纜已從單純的(de)電(dian)(dian)力電(dian)(dian)能傳輸向耐腐、阻燃、阻水(shui)防潮等多功能多用(yong)途方向發(fa)展(zhan)。

隨著高鐵建(jian)設的大(da)力發展，電力電纜在鐵路(lu)供電線(xian)路(lu)中的應用數量(liang)也(ye)在與日俱增，電力電纜的工作(zuo)運(yun)行(xing)狀態(tai)在很大(da)程度(du)上決定著供電質量(liang)和(he)供電的安全性。預防(fang)電纜故障、降低電纜運(yun)行(xing)中的故障率，提(ti)高電纜供電的可靠性，對鐵路(lu)的安全、高效運(yun)行(xing)顯得尤為重(zhong)要。

不管是(shi)用(yong)(yong)于(yu)鐵路供電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)，還是(shi)用(yong)(yong)于(yu)其(qi)(qi)他供電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)，其(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的(de)(de)(de)(de)纜(lan)(lan)(lan)(lan)(lan)芯由于(yu)通過(guo)較大的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流會(hui)在自(zi)身電(dian)(dian)(dian)(dian)(dian)(dian)阻的(de)(de)(de)(de)作用(yong)(yong)下發熱，時(shi)(shi)間(jian)越(yue)久、溫度越(yue)高，電(dian)(dian)(dian)(dian)(dian)(dian)阻越(yue)大、越(yue)容(rong)易發熱，這不僅會(hui)引起(qi)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)傳輸(shu)損耗，更(geng)會(hui)導致絕緣材料退化，毀損電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)，甚至造成火災等(deng)安全事故(gu)，故(gu)而電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的(de)(de)(de)(de)運(yun)行溫度是(shi)表征(zheng)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)運(yun)行狀(zhuang)態的(de)(de)(de)(de)一(yi)個極其(qi)(qi)重(zhong)(zhong)要(yao)的(de)(de)(de)(de)參數，當電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)發生故(gu)障時(shi)(shi)，故(gu)障點(dian)附(fu)近的(de)(de)(de)(de)溫度值也隨之上升或下降(jiang)。由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)往(wang)往(wang)處于(yu)埋設(she)狀(zhuang)態具有極大的(de)(de)(de)(de)隱蔽性，給故(gu)障的(de)(de)(de)(de)檢(jian)測(ce)以及距離的(de)(de)(de)(de)準確定位(wei)帶來較大的(de)(de)(de)(de)難度。重(zhong)(zhong)視電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的(de)(de)(de)(de)故(gu)障檢(jian)測(ce)和診斷(duan)，運(yun)用(yong)(yong)先(xian)進檢(jian)測(ce)技術準確定位(wei)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的(de)(de)(de)(de)故(gu)障點(dian)，及時(shi)(shi)維修，做好安全保護(hu)措施，對電(dian)(dian)(dian)(dian)(dian)(dian)力(li)系(xi)統(tong)的(de)(de)(de)(de)整體運(yun)行極其(qi)(qi)重(zhong)(zhong)要(yao)。

光纖測(ce)溫(wen)(wen)(wen)技術(shu)已在電力電纜(lan)運(yun)行(xing)溫(wen)(wen)(wen)度(du)的(de)監測(ce)中得到運(yun)用，光纖測(ce)溫(wen)(wen)(wen)技術(shu)是一項實(shi)時(shi)、在線和多點光纖溫(wen)(wen)(wen)度(du)測(ce)量(liang)技術(shu)，能夠實(shi)時(shi)地監測(ce)空間溫(wen)(wen)(wen)度(du)場，可以對光纖沿線的(de)測(ce)量(liang)點進行(xing)連續的(de)實(shi)時(shi)測(ce)量(liang)，且抗電磁(ci)干擾。

分布式光纖感溫探測器的價格

1、根據系統測(ce)溫距離咨詢價格

分布式光纖(xian)測溫(wen)系統所應(ying)用的(de)(de)范圍很(hen)多是電纜和管道(dao)、距離從幾公里(li)到幾十公里(li)不同，所使(shi)用的(de)(de)光纜長度(du)會影響系統的(de)(de)價格。

2、根(gen)據(ju)測溫(wen)通道數量(liang)咨詢價格(ge)

從單通(tong)(tong)道(dao)到4通(tong)(tong)道(dao)、8通(tong)(tong)道(dao)等，1通(tong)(tong)道(dao)和多通(tong)(tong)道(dao)的(de)價格(ge)也是不(bu)一樣的(de)。

3、根據(ju)測(ce)溫分辨(bian)率測(ce)溫精度(du)來確定價格

分辨率通常是0.1度(du)(du)，測(ce)溫精度(du)(du)是正負1度(du)(du)。可以定制(zhi)更(geng)高精度(du)(du)的(de)光(guang)纖(xian)測(ce)溫系(xi)統(tong)。
