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、電(dian)伴熱控(kong)制箱的定義:
電伴(ban)熱(re)帶(dai)控(kong)(kong)制箱用于(yu)自限溫電伴(ban)熱(re)帶(dai),恒功率電伴(ban)熱(re)帶(dai),發熱(re)電纜等其他(ta)電熱(re)產品的(de)(de)自動化控(kong)(kong)制的(de)(de)電氣(qi)設備,適用于(yu)防爆,非防爆劑無塵室和無導電塵埃的(de)(de)場所,是(shi)整個電伴(ban)熱(re)系統的(de)(de)中(zhong)樞,內(nei)設有配電系統、數字(zi)顯示溫度(du)控(kong)(kong)制儀表(biao)。
配電系統為電伴熱帶提供電源及短路、負載、漏電安全防護等功能(neng),常用電壓為220V和380V,額定(ding)電流(liu)根(gen)據使用要求可(ke)定(ding)制(zhi),必要時可(ke)加裝穩(wen)壓器和(he)變壓器,故也被稱為“電伴熱帶(dai)配電箱”;溫度控(kong)制(zhi)儀表控(kong)制(zhi)控(kong)制(zhi)伴熱帶(dai)在設定(ding)的(de)范圍(wei)值內運行,達到上限自(zi)動斷電,達到下線自(zi)動送電,并以數字(zi)的(de)方式顯示出來,直觀(guan)明了,操作簡單。
二、電伴(ban)熱(re)控制箱構造:
以電(dian)伴(ban)熱(re)(帶)防爆(bao)控制(zhi)箱為例:包(bao)括電(dian)壓(ya)端(duan)、溫(wen)度控制(zhi)器(qi)(qi)(qi)(qi)、固(gu)態(tai)繼電(dian)器(qi)(qi)(qi)(qi)、散(san)熱(re)器(qi)(qi)(qi)(qi)、溫(wen)度傳感器(qi)(qi)(qi)(qi)和電(dian)伴(ban)熱(re)帶,其(qi)中(zhong)所(suo)述(shu)電(dian)壓(ya)端(duan)分(fen)別與溫(wen)度控制(zhi)器(qi)(qi)(qi)(qi)、固(gu)態(tai)繼電(dian)器(qi)(qi)(qi)(qi)、電(dian)伴(ban)熱(re)帶相連,所(suo)述(shu)溫(wen)度控制(zhi)器(qi)(qi)(qi)(qi)分(fen)別與溫(wen)度傳感器(qi)(qi)(qi)(qi)、固(gu)態(tai)繼電(dian)器(qi)(qi)(qi)(qi)相連,其(qi)他(ta)等,其(qi)中(zhong)核(he)心技術就是溫(wen)度控制(zhi)器(qi)(qi)(qi)(qi)。
三、電伴熱控制箱采(cai)購數量:
電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)帶(dai)控(kong)制箱(xiang)結(jie)合管道伴(ban)熱(re)(re)控(kong)制監測(ce)系(xi)統可與現(xian)在的(de)(de)(de)電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)系(xi)統實現(xian)了真正的(de)(de)(de)智能調控(kong)。在設(she)計電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)控(kong)制箱(xiang),需要考(kao)慮選(xuan)型,每回路(lu)需按電(dian)(dian)(dian)(dian)熱(re)(re)帶(dai)的(de)(de)(de)啟(qi)動(dong)電(dian)(dian)(dian)(dian)流(liu)(自限溫電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)帶(dai))工(gong)作電(dian)(dian)(dian)(dian)流(liu),考(kao)慮交流(liu)接觸器熱(re)(re)平衡時回路(lu)電(dian)(dian)(dian)(dian)流(liu)不(bu)大于所(suo)選(xuan)的(de)(de)(de)電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)帶(dai)的(de)(de)(de)啟(qi)動(dong)、工(gong)作電(dian)(dian)(dian)(dian)流(liu))等元素。電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)帶(dai)控(kong)制箱(xiang)的(de)(de)(de)量應該按照圖紙的(de)(de)(de)設(she)計和圖紙說明來計算。按照電(dian)(dian)(dian)(dian)伴(ban)熱(re)(re)帶(dai)的(de)(de)(de)功率和回路(lu)數來確定的(de)(de)(de)。例(li)如 1回路(可控(kong)100米電(dian)伴熱帶)。同時電(dian)伴熱控制(溫(wen)控)箱內(nei)均設(she)置的有溫(wen)度調節(jie)旋鈕(niu),用戶(hu)直接通過溫(wen)度調節(jie)旋鈕(niu)設(she)定溫(wen)度即可。
