在大型電伴熱工程項目施工中，由于電伴熱帶數量和回路較多，為了達到集中控制和用電安全等就需要使用到電伴熱控制箱。而電伴熱控制箱也能夠自動控制該介質保持一定的溫度。那么電伴熱控制箱是怎么控制電伴熱帶的呢，下面小編就給大家介紹一下。

  一(yi)、電伴(ban)熱控(kong)制箱的定義：

  電(dian)(dian)伴熱(re)帶控制(zhi)(zhi)箱用(yong)于(yu)自(zi)限(xian)溫(wen)電(dian)(dian)伴熱(re)帶，恒(heng)功率電(dian)(dian)伴熱(re)帶，發(fa)熱(re)電(dian)(dian)纜等其他電(dian)(dian)熱(re)產品的自(zi)動化控制(zhi)(zhi)的電(dian)(dian)氣設(she)備，適用(yong)于(yu)防(fang)爆，非防(fang)爆劑(ji)無塵室(shi)和(he)無導電(dian)(dian)塵埃的場所，是整個電(dian)(dian)伴熱(re)系統的中樞，內(nei)設(she)有配電(dian)(dian)系統、數(shu)字顯示溫(wen)度控制(zhi)(zhi)儀表。

  配電(dian)(dian)系(xi)統為(wei)電(dian)(dian)伴熱帶提供電(dian)(dian)源(yuan)及短(duan)路、負(fu)載、漏電(dian)(dian)安全防護等(deng)功(gong)能，常用電(dian)(dian)壓為(wei)220V和380V，額定電流根據(ju)使用(yong)要求可(ke)定制(zhi)(zhi)，必(bi)要時可(ke)加裝穩壓器(qi)和變壓器(qi)，故也被(bei)稱為(wei)“電伴熱帶配電箱(xiang)”；溫(wen)度控(kong)制(zhi)(zhi)儀表控(kong)制(zhi)(zhi)控(kong)制(zhi)(zhi)伴熱帶在設定的(de)范圍值內運(yun)行，達到(dao)上限(xian)自動斷電，達到(dao)下(xia)線(xian)自動送電，并以數字的(de)方式顯(xian)示出來(lai)，直觀明了(le)，操作簡單。

  二、電伴熱控(kong)制箱構(gou)造：

  以電(dian)伴(ban)熱（帶(dai)）防爆控(kong)(kong)制(zhi)(zhi)箱(xiang)為例(li)：包(bao)括電(dian)壓端、溫(wen)度(du)(du)(du)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)、固(gu)態繼(ji)電(dian)器(qi)(qi)、散熱器(qi)(qi)、溫(wen)度(du)(du)(du)傳(chuan)感(gan)器(qi)(qi)和電(dian)伴(ban)熱帶(dai)，其中所述電(dian)壓端分別與(yu)(yu)溫(wen)度(du)(du)(du)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)、固(gu)態繼(ji)電(dian)器(qi)(qi)、電(dian)伴(ban)熱帶(dai)相(xiang)連(lian)，所述溫(wen)度(du)(du)(du)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)分別與(yu)(yu)溫(wen)度(du)(du)(du)傳(chuan)感(gan)器(qi)(qi)、固(gu)態繼(ji)電(dian)器(qi)(qi)相(xiang)連(lian)，其他等，其中核心(xin)技術(shu)就是溫(wen)度(du)(du)(du)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)。

  三、電伴熱(re)控制箱采(cai)購數(shu)量(liang)：

  電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)帶(dai)控(kong)制箱結合管道伴(ban)(ban)熱(re)(re)(re)控(kong)制監測系統(tong)可與現(xian)在(zai)(zai)的(de)(de)(de)電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)系統(tong)實(shi)現(xian)了(le)真正的(de)(de)(de)智能調(diao)控(kong)。在(zai)(zai)設計電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)控(kong)制箱，需要考(kao)(kao)慮選(xuan)型，每回(hui)路(lu)需按(an)電(dian)(dian)熱(re)(re)(re)帶(dai)的(de)(de)(de)啟動電(dian)(dian)流(liu)(liu)（自(zi)限溫電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)帶(dai)）工(gong)作電(dian)(dian)流(liu)(liu)，考(kao)(kao)慮交流(liu)(liu)接觸(chu)器熱(re)(re)(re)平(ping)衡時回(hui)路(lu)電(dian)(dian)流(liu)(liu)不(bu)大(da)于所(suo)選(xuan)的(de)(de)(de)電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)帶(dai)的(de)(de)(de)啟動、工(gong)作電(dian)(dian)流(liu)(liu)）等元素。電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)帶(dai)控(kong)制箱的(de)(de)(de)量應該按(an)照(zhao)圖(tu)紙的(de)(de)(de)設計和圖(tu)紙說明來計算。按(an)照(zhao)電(dian)(dian)伴(ban)(ban)熱(re)(re)(re)帶(dai)的(de)(de)(de)功率(lv)和回(hui)路(lu)數來確(que)定(ding)的(de)(de)(de)。例如 1回路（可控100米電伴(ban)熱(re)帶）。同時電伴(ban)熱(re)控(kong)制(zhi)（溫控(kong)）箱(xiang)內均設(she)置的有溫度(du)調節旋鈕(niu)，用戶直接(jie)通(tong)過溫度(du)調節旋鈕(niu)設(she)定溫度(du)即可。
