自限溫電伴熱帶的發熱原理
電(dian)(dian)伴熱(re)(re)帶(dai)是(shi)(shi)由(you)電(dian)(dian)能轉化為熱(re)(re)能對管道介質進行熱(re)(re)補償的一種保(bao)溫產(chan)品。應用區域十分廣(guang)泛,如(ru)電(dian)(dian)廠、化工、石油(you)、消防、建筑及民用太陽能管道等,電(dian)(dian)伴熱(re)(re)帶(dai)作用防凍保(bao)溫,可(ke)分為自限溫電(dian)(dian)伴熱(re)(re)帶(dai)、恒功率電(dian)(dian)伴熱(re)(re)帶(dai)、MI加熱(re)(re)電(dian)(dian)纜(lan)和發熱(re)(re)電(dian)(dian)纜(lan)等四大類型,每一種電(dian)(dian)伴熱(re)(re)帶(dai)都有不同(tong)的功能和不同(tong)的用途,其發熱(re)(re)原理也是(shi)(shi)不同(tong)的
自限溫(wen)電伴(ban)熱表面應光(guang)潔、無(wu)油污(wu)(伴(ban)熱帶污(wu)染其(qi)所需伴(ban)熱物(wu)體介質,尤其(qi)是(shi)在電伴(ban)熱帶使(shi)用于石油化工等區,若不選擇適合的(de)(de)材料會(hui)導致污(wu)染,或者是(shi)在高溫(wen)工作下,散發刺鼻的(de)(de)塑料的(de)(de)味道)、刺現象(xiang)(影響電伴(ban)熱外護套的(de)(de)防護型(xing)和與管道的(de)(de)接(jie)觸面,避免應此現象(xiang)造成伴(ban)熱物(wu)體容器(qi)表面出(chu)現被“燙壞(huai)”的(de)(de)灰(hui)跡)
針對于防爆電(dian)伴熱金屬編織層外的外護套應選擇(ze)阻燃(ran)型的材質(zhi),并且保證(zheng)護套完(wan)整性,可通過火(huo)花(hua)試(shi)驗(yan)(yan)(yan)進行檢驗(yan)(yan)(yan)此項性能,試(shi)驗(yan)(yan)(yan)電(dian)(dian)(dian)壓(ya)3000V,試(shi)驗(yan)(yan)(yan)電(dian)(dian)(dian)壓(ya)施加在(zai)編織層與(yu)火(huo)花(hua)機表面電(dian)(dian)(dian)極之間。
電(dian)(dian)(dian)伴(ban)(ban)熱(re)帶(dai)(dai)(dai)的(de)構成(cheng):是在(zai)兩根(gen)(gen)平行(xing)(xing)母(mu)線之(zhi)間均(jun)勻的(de)加上聚錄乙烯(xi)或塑質材(cai)料加工(gong)形(xing)成(cheng)的(de)芯帶(dai)(dai)(dai)。是在(zai)高(gao)溫融化(hua)覆蓋,在(zai)進行(xing)(xing)冷卻定(ding)型之(zhi)后(hou)形(xing)成(cheng)。當它(ta)們(men)跨接在(zai)兩根(gen)(gen)平行(xing)(xing)母(mu)線上時,就構成(cheng)芯帶(dai)(dai)(dai)的(de)回路。電(dian)(dian)(dian)伴(ban)(ban)熱(re)帶(dai)(dai)(dai)一端的(de)兩根(gen)(gen)母(mu)線接通供電(dian)(dian)(dian)電(dian)(dian)(dian)源后(hou),電(dian)(dian)(dian)流從(cong)一根(gen)(gen)母(mu)線流過(guo)到達另一根(gen)(gen)母(mu)線形(xing)成(cheng)回路。這(zhe)二根(gen)(gen)母(mu)線通過(guo)其的(de)電(dian)(dian)(dian)阻值(zhi)進行(xing)(xing)發熱(re),將電(dian)(dian)(dian)能轉化(hua)成(cheng)熱(re)能,在(zai)通過(guo)包裹層對管道等設備進行(xing)(xing)伴(ban)(ban)熱(re)保溫。如果(guo)芯帶(dai)(dai)(dai)溫度(du)升到相應(ying)的(de)極限溫度(du)時,這(zhe)時的(de)電(dian)(dian)(dian)阻值(zhi)無法在(zai)提(ti)供較(jiao)高(gao)的(de)溫度(du),芯帶(dai)(dai)(dai)的(de)溫度(du)即已經(jing)達到高(gao)額定(ding)值(zhi),這(zhe)時就是自(zi)(zi)動控(kong)制電(dian)(dian)(dian)伴(ban)(ban)熱(re)帶(dai)(dai)(dai)的(de)溫度(du)不再升高(gao)(自(zi)(zi)控(kong)溫度(du))。
