廣州高溫線纜發熱原理和基本原理是什么
1、廣州高溫線纜發熱原理
發熱電(dian)纜(lan)內芯由(you)(you)冷線(xian)熱 線(xian)組成(cheng),外面(mian)由(you)(you)絕緣層、接地、屏(ping) 蔽層和外護套組成(cheng),制(zhi)成(cheng)電(dian)纜(lan)結構(gou),以電(dian)力為(wei)能源,利用合金電(dian)阻絲進行(xing)通電(dian)發熱,并在40~65℃的溫度間運(yun)行(xing),來(lai)達到采暖(nuan)或者(zhe)保溫的效果。一般有單導和雙導之分,每種線(xian)的功率范圍為(wei)每米10W~20W。
2、廣州(zhou)高溫(wen)線纜的缺陷
功率(lv)(lv)配置要求(qiu)(qiu)高(gao),大面積使用(yong)時對電(dian)容有較高(gao)的要求(qiu)(qiu)。電(dian)纜線內是220V的電(dian)壓(ya),一旦電(dian)線老化開裂,容易(yi)造成觸電(dian)危險。電(dian)纜線對水泥層(ceng)要求(qiu)(qiu)達到(dao)3-4公分(fen),影響(xiang)到(dao)層(ceng)高(gao),且增加了蓄熱損耗,熱導效(xiao)應慢(man)。功率(lv)(lv)較高(gao),能耗大,使用(yong)時如(ru)果不注意(yi),費用(yong)會很高(gao)。設計要求(qiu)(qiu)精(jing)度高(gao),且安裝要求(qiu)(qiu)也高(gao)。
3、廣州高溫線(xian)纜基本結構
目前(qian),在(zai)(zai)市場上常(chang)見的室(shi)內(nei)采暖用發(fa)熱(re)電(dian)(dian)(dian)纜(lan),從發(fa)熱(re)芯(xin)的數(shu)量區分,分為單(dan)導(dao)(dao)電(dian)(dian)(dian)纜(lan)和雙導(dao)(dao)電(dian)(dian)(dian)纜(lan)兩種。單(dan)導(dao)(dao)電(dian)(dian)(dian)纜(lan)內(nei)部(bu)(bu)只(zhi)有(you)一根(gen)發(fa)熱(re)芯(xin),電(dian)(dian)(dian)纜(lan)本身不(bu)成回路,在(zai)(zai)接(jie)(jie)線時(shi),電(dian)(dian)(dian)纜(lan)兩端(duan)都(dou)需要與供電(dian)(dian)(dian)電(dian)(dian)(dian)源(yuan)相聯(lian)接(jie)(jie)。而雙導(dao)(dao)電(dian)(dian)(dian)纜(lan)內(nei)部(bu)(bu)有(you)兩根(gen)芯(xin),電(dian)(dian)(dian)纜(lan)自(zi)成回路,在(zai)(zai)電(dian)(dian)(dian)纜(lan)尾部(bu)(bu),發(fa)熱(re)芯(xin)折回,接(jie)(jie)線時(shi)只(zhi)要連(lian)接(jie)(jie)電(dian)(dian)(dian)纜(lan)的接(jie)(jie)線端(duan)即可。
4、廣州高溫線纜價格及耗電量
發(fa)熱電纜的(de)(de)造價(jia)與很多(duo)因素有關系,例(li)如房(fang)(fang)間保溫、層(ceng)高、門窗尺(chi)寸(cun)、客戶特殊要求等情況,計算(suan)房(fang)(fang)間的(de)(de)熱負荷,確(que)定(ding)功率(lv),選擇電纜的(de)(de)型號,確(que)定(ding)出發(fa)熱電纜造價(jia)。電地暖(nuan)的(de)(de)耗電量每天每平方0.3-0.4度電。
5、廣州高溫線纜地暖系統構成
發(fa)熱(re)(re)電(dian)(dian)(dian)纜(lan)(lan)采暖系(xi)(xi)統(tong)由發(fa)熱(re)(re)電(dian)(dian)(dian)纜(lan)(lan)和溫(wen)(wen)(wen)控器(qi)兩部(bu)分(fen)組成,發(fa)熱(re)(re)電(dian)(dian)(dian)纜(lan)(lan)鋪設于地(di)面中,溫(wen)(wen)(wen)控器(qi)安(an)裝于墻(qiang)面上(shang)。當室內(nei)環境溫(wen)(wen)(wen)度(du)或地(di)面溫(wen)(wen)(wen)度(du)低于溫(wen)(wen)(wen)控器(qi)設定(ding)的(de)溫(wen)(wen)(wen)度(du)時(shi),溫(wen)(wen)(wen)控器(qi)接通電(dian)(dian)(dian)源,發(fa)熱(re)(re)電(dian)(dian)(dian)纜(lan)(lan)通電(dian)(dian)(dian)后開始發(fa)熱(re)(re)升溫(wen)(wen)(wen),發(fa)出的(de)熱(re)(re)量被覆蓋(gai)著的(de)水泥層(ceng)吸收,然(ran)后均勻地(di)加熱(re)(re)室內(nei)空氣,還有(you)一部(bu)分(fen)熱(re)(re)量以(yi)遠紅外輻射的(de)方(fang)式直接釋放到室內(nei)。該種方(fang)式的(de)采暖系(xi)(xi)統(tong)把整(zheng)個地(di)面作為散熱(re)(re)器(qi),室內(nei)溫(wen)(wen)(wen)度(du)上(shang)層(ceng)低而(er)(er)下層(ceng)高,有(you)溫(wen)(wen)(wen)足而(er)(er)頂涼的(de)感受,使您感到舒 適而(er)(er)自然(ran)。
