自限溫電伴熱帶又稱為自控溫電伴熱帶、自控溫伴熱電纜，是新一代帶狀恒溫電熱產品，能夠進行自動模式限制發熱時的溫度，并隨被伴熱體的溫度可以自動通過調節系統輸出信號功率而無任何一個附加服務設備。自限溫電熱帶地區作為電伴熱帶中使用率較多的一款電子產品，然而我國不少學生用戶在使用自限溫伴熱帶時經常自己遇到伴熱帶啟動工(gong)作(zuo)電流過大的問題。
自(zi)限溫度、恒功(gong)率與熱帶不同(tong)，屬(shu)于變功(gong)率型產品(pin)，安(an)裝后須(xu)***注意(yi)初始(shi)啟動電流很大(da)，因此用戶(hu)須(xu)***采取措施防止熱帶啟動電流過大(da)引起短路、燃燒等現象(xiang)。
針對自(zi)(zi)限(xian)(xian)(xian)(xian)溫電(dian)(dian)(dian)伴熱(re)帶(dai)啟動(dong)(dong)工作電(dian)(dian)(dian)流(liu)(liu)產生過大的(de)(de)情況。我們教師(shi)可(ke)以進行(xing)考慮企(qi)業使(shi)用系統自(zi)(zi)動(dong)(dong)限(xian)(xian)(xian)(xian)流(liu)(liu)器(qi)(qi)，讓伴熱(re)帶(dai)啟動(dong)(dong)電(dian)(dian)(dian)流(liu)(liu)可(ke)控(kong)(kong)制(zhi)在自(zi)(zi)己一定能夠(gou)合理的(de)(de)范(fan)圍。自(zi)(zi)動(dong)(dong)限(xian)(xian)(xian)(xian)流(liu)(liu)器(qi)(qi)名為(wei)自(zi)(zi)動(dong)(dong)緩流(liu)(liu)器(qi)(qi)，電(dian)(dian)(dian)壓(ya)及功率為(wei)220V/25-60W，自(zi)(zi)動(dong)(dong)限(xian)(xian)(xian)(xian)流(liu)(liu)器(qi)(qi)其(qi)主要(yao)信息技術(shu)發展特征是所述的(de)(de)限(xian)(xian)(xian)(xian)流(liu)(liu)器(qi)(qi)保護盒(he)內設有與(yu)負載串聯連接的(de)(de)自(zi)(zi)動(dong)(dong)調(diao)壓(ya)線路(lu)板，自(zi)(zi)動(dong)(dong)調(diao)壓(ya)電(dian)(dian)(dian)器(qi)(qi)由自(zi)(zi)動(dong)(dong)分析單(dan)元(yuan)(yuan)設計電(dian)(dian)(dian)路(lu)結(jie)構單(dan)元(yuan)(yuan)內部控(kong)(kong)制(zhi)可(ke)控(kong)(kong)硅控(kong)(kong)制(zhi)導通、延時電(dian)(dian)(dian)路(lu)基本單(dan)元(yuan)(yuan)質量控(kong)(kong)制(zhi)時間繼(ji)電(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)路(lu)單(dan)元(yuan)(yuan)和直流(liu)(liu)供電(dian)(dian)(dian)電(dian)(dian)(dian)路(lu)主要(yao)組成。
自動限流(liu)器(qi)是(shi)為(wei)負載大(da)起動電(dian)流(liu)而設(she)計的一(yi)種(zhong)儀器(qi)，但負載通(tong)電(dian)后電(dian)流(liu)迅(xun)速下降，***終達到(dao)平(ping)衡狀態。
但是現在隨著電伴熱帶廠家配方和工藝生產的提高，電伴熱帶的啟動電流已經降到了很小的水平，所以用戶在購買電伴熱帶的時(shi)候還是要選擇正(zheng)規的有質量保證的廠家。
