自限溫電伴熱帶使用廣泛，在石油、化工、電力、建筑領域均有涉及。然而在使用過程中有些用戶反映了自限溫電伴熱帶使用時啟動電流大，對于這個問題可以怎么解決呢，下面就給大家講解一下。
我們先(xian)來了解(jie)一下(xia)自限(xian)溫(wen)(wen)(wen)電(dian)伴熱(re)(re)帶(dai)的(de)(de)性能(neng)。自限(xian)溫(wen)(wen)(wen)電(dian)伴熱(re)(re)帶(dai)屬(shu)平(ping)行電(dian)阻(zu)結構(gou)，具有很高的(de)(de)正(zheng)溫(wen)(wen)(wen)度(du)系數“PTC”，溫(wen)(wen)(wen)度(du)可以自我調節，達到溫(wen)(wen)(wen)度(du)平(ping)衡的(de)(de)效果。自限(xian)溫(wen)(wen)(wen)電(dian)伴熱(re)(re)帶(dai)由納米導(dao)電(dian)碳粒、兩根平(ping)行母線(xian)外(wai)、絕緣層、屏蔽層和外(wai)護套構(gou)成。由于這(zhe)種平(ping)行結構(gou)，自限(xian)溫(wen)(wen)(wen)電(dian)伴熱(re)(re)帶(dai)可以在(zai)現場被切割(ge)成任何長度(du)，并且采用接(jie)(jie)線(xian)盒連接(jie)(jie)。自限(xian)溫(wen)(wen)(wen)電(dian)伴熱(re)(re)帶(dai)的(de)(de)技術指(zhi)標(biao)中一項(xiang)重要(yao)指(zhi)標(biao)啟動電(dian)流(liu)是(shi)指(zhi)在(zai)電(dian)伴熱(re)(re)帶(dai)接(jie)(jie)通電(dian)源時，瞬(shun)間(jian)產(chan)生的(de)(de)電(dian)流(liu)的(de)(de)峰值，這(zhe)項(xiang)指(zhi)標(biao)也(ye)限(xian)制了電(dian)伴熱(re)(re)帶(dai)的(de)(de)使用長度(du)。
自限(xian)(xian)溫電(dian)(dian)(dian)伴熱帶啟(qi)動(dong)時為(wei)了避(bi)免啟(qi)動(dong)電(dian)(dian)(dian)流(liu)過(guo)(guo)大(da)(da)，可以采用自動(dong)限(xian)(xian)流(liu)器對啟(qi)動(dong)電(dian)(dian)(dian)流(liu)做控(kong)制，避(bi)免啟(qi)動(dong)電(dian)(dian)(dian)流(liu)過(guo)(guo)大(da)(da)而發生(sheng)短路現象。自動(dong)限(xian)(xian)流(liu)器專為(wei)負(fu)載啟(qi)動(dong)電(dian)(dian)(dian)流(liu)大(da)(da)，但隨著負(fu)載通(tong)電(dian)(dian)(dian)后電(dian)(dian)(dian)流(liu)又很快下(xia)降，達到(dao)一個平衡(heng)狀(zhuang)態(tai)而設(she)(she)計的(de)儀表(biao)，它獨特的(de)設(she)(she)備(bei)工藝性(xing)能，可以自動(dong)改變可控(kong)硅控(kong)制的(de)極的(de)導電(dian)(dian)(dian)角(jiao)，使(shi)加在(zai)負(fu)載兩端的(de)電(dian)(dian)(dian)壓逐步增大(da)(da)，使(shi)得(de)負(fu)載通(tong)電(dian)(dian)(dian)后的(de)電(dian)(dian)(dian)流(liu)下(xia)降達到(dao)平衡(heng)狀(zhuang)態(tai)。
