1.工作原理： 

三根平(ping)行絕緣(yuan)(yuan)銅(tong)絞(jiao)線為(wei)電(dian)源(yuan)母線，在內護套(tao)絕緣(yuan)(yuan)層外纏繞(rao)電(dian)熱絲，并將該電(dian)熱絲每隔一定距(ju)離（即“發(fa)熱節長"）分別依次與電(dian)源(yuan)母線AB-BC-CA-AB......反復循環連接，在每三相間形甩(shuai)連續并聯(lian)電(dian)阻(zu)(zu)。當線母通以三相電(dian)后，各并聯(lian)電(dian)阻(zu)(zu)同(tong)時(shi)發(fa)熱，因而形成一條(tiao)連續三相電(dian)的加熱帶。

DXW/PZ/J 型自限式電熱帶 

自限式電(dian)熱(re)帶 

型號含義： 

例： DXW-PZ/J表示：絕緣材料為PTC復合性，額(e)定工作電壓(ya)為220V、20℃時每(mei)米輸出功率20W的自限工電熱帶。 

工作原理：兩根銅(tong)絞(jiao)線為電(dian)(dian)(dian)(dian)源(yuan)(yuan)母線，在母線周圍擠塑一層有正溫(wen)(wen)(wen)系數(shu)特(te)性(xing)的(de)(de)自(zi)(zi)限(xian)(xian)發(fa)(fa)熱(re)(re)芯(xin)料，當接通(tong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)后(hou)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)橫向(xiang)通(tong)過(guo)芯(xin)料，形(xing)成了一個連續的(de)(de)并聯加熱(re)(re)體。本電(dian)(dian)(dian)(dian)熱(re)(re)帶(dai)發(fa)(fa)熱(re)(re)芯(xin)料采用經特(te)種工藝(yi)處理的(de)(de)溫(wen)(wen)(wen)度(du)(du)(du)記憶導電(dian)(dian)(dian)(dian)分(fen)子(zi)。當電(dian)(dian)(dian)(dian)流(liu)通(tong)過(guo)網絡導電(dian)(dian)(dian)(dian)分(fen)子(zi)時，產生熱(re)(re)量(liang)。在冷態時，電(dian)(dian)(dian)(dian)流(liu)易(yi)于通(tong)過(guo)，產生大量(liang)熱(re)(re)能。隨著(zhu)溫(wen)(wen)(wen)度(du)(du)(du)升高，基體膨脹，導電(dian)(dian)(dian)(dian)分(fen)子(zi)減(jian)(jian)低了網絡密度(du)(du)(du)，切(qie)斷(duan)了大部分(fen)通(tong)路(lu)，電(dian)(dian)(dian)(dian)流(liu)減(jian)(jian)少(shao)(shao)，發(fa)(fa)熱(re)(re)量(liang)隨之減(jian)(jian)少(shao)(shao)，由此，達到自(zi)(zi)動控制溫(wen)(wen)(wen)度(du)(du)(du)目的(de)(de)，使加熱(re)(re)基本超于熱(re)(re)平(ping)衡。當溫(wen)(wen)(wen)度(du)(du)(du)下降，溫(wen)(wen)(wen)度(du)(du)(du)記憶導電(dian)(dian)(dian)(dian)分(fen)子(zi)再(zai)次收縮，結(jie)果，原先切(qie)斷(duan)的(de)(de)電(dian)(dian)(dian)(dian)路(lu)有恢復接通(tong)，電(dian)(dian)(dian)(dian)流(liu)再(zai)次增(zeng)大，熱(re)(re)量(liang)輸出(chu)增(zeng)加。這種特(te)性(xing)稱之謂：“溫(wen)(wen)(wen)度(du)(du)(du)自(zi)(zi)限(xian)(xian)式特(te)性(xing)"，“自(zi)(zi)限(xian)(xian)式電(dian)(dian)(dian)(dian)熱(re)(re)帶(dai)"名稱由此而產生。
