電線發燙什么原因
1、電線(xian)導體電阻不符合要求(qiu),會導致電線(xian)在運(yun)行過(guo)程(cheng)中過(guo)熱。
2、電線的部分護套受(shou)損(sun)(sun),進水后對絕(jue)緣性能(neng)的損(sun)(sun)害緩(huan)慢,導致絕(jue)緣電阻逐漸降(jiang)低,并且在(zai)運行過(guo)(guo)程中還(huan)會導致電線過(guo)(guo)熱。
3、在安(an)裝(zhuang)過(guo)程中,電線布(bu)置得過(guo)于密集,導致通(tong)風(feng)和(he)散熱不(bu)良(liang)。
4、電(dian)線與其他熱源距離(li)太(tai)近(jin),導(dao)致異(yi)常散熱。
5、接(jie)頭(tou)制(zhi)造(zao)技術不好(hao),壓接(jie)不緊密(mi),導致接(jie)頭(tou)處的接(jie)觸電阻過(guo)大,從(cong)而導致電線(xian)過(guo)熱(re)。
電線發燙可以繼續用嗎
當電線(xian)(xian)非常發(fa)(fa)燙(tang)時,建議不要繼(ji)續(xu)使用它(ta), 注意環(huan)境散發(fa)(fa)熱量(liang)。 電線(xian)(xian)太(tai)細和電子過(guo)載會導致電線(xian)(xian)發(fa)(fa)燙(tang), 長期發(fa)(fa)燙(tang)很容易(yi)導致電線(xian)(xian)老化和短(duan)路。
電線發燙會有什么后果
電線產生(sheng)發(fa)熱現象(xiang)后,如不找到原因及(ji)時排除故障,電線繼續連續通電運行后將產生(sheng)絕緣熱擊穿現象(xiang)。造(zao)成電線發(fa)生(sheng)相間(jian)短路(lu)跳(tiao)閘現象(xiang),嚴重的可能(neng)引起(qi)火災。
電線發燙怎么辦
1、檢查(cha)室內、外的總開關,接線(xian)端子的螺絲是否松動,檢查(cha)插(cha)座(zuo),開關,燈具等的接線(xian)端子是否松動。
2、檢(jian)查線路導線線徑,穿管數量(liang)等是否過多過密,是否與負荷匹配等。
3、檢查(cha)是否使用了(le)功(gong)率較(jiao)大(da)的(de)用電(dian)(dian)(dian)(dian)(dian)(dian)器(qi),如(ru):電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)毯,電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)水(shui)器(qi),電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)風機,電(dian)(dian)(dian)(dian)(dian)(dian)爐(lu),電(dian)(dian)(dian)(dian)(dian)(dian)磁爐(lu),微波爐(lu),電(dian)(dian)(dian)(dian)(dian)(dian)烤爐(lu)等用電(dian)(dian)(dian)(dian)(dian)(dian)加熱(re)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)和空調等。如(ru)果(guo)有,就迅速切斷這些電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan),然(ran)后再(zai)檢查(cha)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)的(de)發熱(re)情況。如(ru)果(guo)發熱(re)減少或消失,說明是負荷大(da)引(yin)起電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)過流發熱(re),應該(gai)分開使用,不(bu)能(neng)同時使用多個(ge)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。
4、建議找專業人員來更換電線,這樣可以減輕負擔。
5、如果(guo)異常高溫,請考慮此時更(geng)換插座(zuo)或插頭,插頭與插座(zuo)之間的接觸(chu)不(bu)良會導致插頭發燙。
6、如(ru)果新電線很發燙,這時就要注意看看新插頭內電線是否松動,這是由于生(sheng)產過程粗糙和(he)其他原因造成的。
