電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)短路(lu)(lu)的原因及解決方法電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)引起短路(lu)(lu)的原因很多。一般來說，電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)的使用(yong)(yong)環(huan)境比較潮濕。露天，外保(bao)(bao)溫無防(fang)水層(ceng)，電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)接(jie)(jie)頭(tou)處(chu)不保(bao)(bao)溫不防(fang)水或安裝不規范。當(dang)電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)短路(lu)(lu)，電(dian)流突然(ran)增大(da)時(shi)(shi)，其瞬時(shi)(shi)熱(re)(re)(re)(re)(re)量會遠遠超(chao)過(guo)線(xian)(xian)路(lu)(lu)正常工作時(shi)(shi)的發(fa)(fa)熱(re)(re)(re)(re)(re)量，容易引發(fa)(fa)事故。因此，當(dang)電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)短接(jie)(jie)或過(guo)熱(re)(re)(re)(re)(re)一段(duan)時(shi)(shi)間后，需要立即切斷電(dian)源(yuan)，檢測故障點，停(ting)止(zhi)使用(yong)(yong)。電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)發(fa)(fa)生短路(lu)(lu)時(shi)(shi)，應妥善處(chu)理伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)接(jie)(jie)頭(tou)，伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)接(jie)(jie)頭(tou)應做成不等邊形，并清潔(jie)周圍絕(jue)緣層(ceng)外皮，露出內線(xian)(xian)芯。如(ru)果是防(fang)爆伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)，應剝去外屏蔽網線(xian)(xian)。在上述基(ji)礎上，電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)的接(jie)(jie)頭(tou)應做防(fang)水處(chu)理。兩(liang)根線(xian)(xian)芯可以分別用(yong)(yong)銅套固(gu)定，然(ran)后用(yong)(yong)熱(re)(re)(re)(re)(re)縮管(guan)做防(fang)水絕(jue)緣處(chu)理，再用(yong)(yong)熱(re)(re)(re)(re)(re)縮管(guan)從伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)的絕(jue)緣到兩(liang)根電(dian)源(yuan)線(xian)(xian)之間的空間做二(er)次絕(jue)緣和防(fang)水處(chu)理，防(fang)止(zhi)電(dian)伴(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)(dai)(dai)發(fa)(fa)熱(re)(re)(re)(re)(re)元件(jian)滲水和兩(liang)根線(xian)(xian)芯接(jie)(jie)觸造(zao)成短路(lu)(lu)。
