　　1、同時還要注意(yi)防(fang)凍傳(chuan)(chuan)感(gan)器要安(an)裝在管(guan)道的(de)上(shang)部(即電伴(ban)熱帶的(de)相反方向);不(bu)能將(jiang)防(fang)凍傳(chuan)(chuan)感(gan)器直接和電伴(ban)熱帶接觸(chu)，這樣就不(bu)能準確的(de)檢測到管(guan)道的(de)實際(ji)溫(wen)度。

　2、采用(yong)其(qi)他敷設方式(shi)時(shi)，同樣要注意防凍傳感(gan)器的安裝(zhuang)位置，將其(qi)放(fang)在管道溫度點上(shang)為。

　　3、施工過程中，要注(zhu)意(yi)檢查電伴熱(re)帶的表(biao)面(mian)不能有劃傷、裂痕等，一旦發現立即更換。

　　4、除了安裝(zhuang)智能儀表(biao)能夠控制電(dian)(dian)伴熱(re)帶(dai)工作(zuo)以(yi)外，單獨(du)使用電(dian)(dian)伴熱(re)帶(dai)防凍的(de)(de)，電(dian)(dian)源(yuan)輸入端必(bi)須安裝(zhuang)漏電(dian)(dian)保護裝(zhuang)置，不能直接(jie)使用普通的(de)(de)三端插(cha)頭。接(jie)地(di)保護線要與敷設電(dian)(dian)伴熱(re)帶(dai)的(de)(de)管道可(ke)靠連接(jie)。這(zhe)樣，一旦(dan)電(dian)(dian)伴熱(re)帶(dai)出(chu)現漏電(dian)(dian)現象時，漏電(dian)(dian)保護裝(zhuang)置才能可(ke)靠的(de)(de)動作(zuo)切斷(duan)電(dian)(dian)源(yuan)保證(zheng)安全。

　　電(dian)(dian)(dian)伴(ban)熱(re)(re)系(xi)統在(zai)(zai)垃圾焚燒(shao)發電(dian)(dian)(dian)廠的(de)應用主要是為了防止垃圾焚燒(shao)后飛(fei)灰(hui)在(zai)(zai)設(she)備表(biao)面凝結。電(dian)(dian)(dian)伴(ban)熱(re)(re)可保證灰(hui)斗在(zai)(zai)長(chang)期設(she)定溫(wen)(wen)(wen)度(du)下，防止灰(hui)塵濕凝、積灰(hui)、堵塞(sai)。電(dian)(dian)(dian)伴(ban)熱(re)(re)可以加(jia)熱(re)(re)灰(hui)斗外壁(bi)，補(bu)充(chong)灰(hui)斗外壁(bi)溫(wen)(wen)(wen)差(cha)，達到(dao)(dao)除濕、暢(chang)通的(de)目的(de)。然后將(jiang)灰(hui)斗壁(bi)溫(wen)(wen)(wen)升高到(dao)(dao)設(she)定的(de)保溫(wen)(wen)(wen)溫(wen)(wen)(wen)度(du)。當達到(dao)(dao)保溫(wen)(wen)(wen)溫(wen)(wen)(wen)度(du)時，灰(hui)斗加(jia)熱(re)(re)系(xi)統將(jiang)根據該溫(wen)(wen)(wen)度(du)進行(xing)熱(re)(re)循環(huan)。
