五、很(hen)安全(quan)耗(hao)電防(fang)(fang)火(huo)防(fang)(fang)燃方(fang)式

1、進行施工活動現場發生著火的具體問題

（1）電(dian)氣線(xian)路(lu)負荷過大引起火(huo)災、線(xian)路(lu)上的電(dian)氣設備長(chang)時間超負荷使(shi)用，使(shi)用電(dian)流超過了導線(xian)的安全(quan)載(zai)流量這(zhe)時如果保護(hu)裝(zhuang)置選擇不合理，時間過長(chang)，線(xian)芯過熱使(shi)絕緣層(ceng)損壞燃燒，造(zao)成火(huo)災。

（2）線(xian)路短(duan)路引(yin)起火(huo)災、因(yin)導(dao)(dao)線(xian)安全部距不(bu)夠(gou)，絕緣(yuan)等(deng)級不(bu)夠(gou)，所久老(lao)化(hua)(hua)、破損等(deng)或人為操作(zuo)不(bu)等(deng)原因(yin)造成線(xian)路短(duan)路，強(qiang)大(da)的(de)短(duan)路電流很快轉(zhuan)換成熱能(neng)，使導(dao)(dao)線(xian)嚴重發(fa)熱，溫度急劇升高，造成導(dao)(dao)線(xian)熔化(hua)(hua)，絕緣(yuan)層燃燒，引(yin)起火(huo)災。

（3）接觸電阻(zu)過大引起火災(zai)；導線(xian)接頭接不(bu)好，接線(xian)柱壓接不(bu)實，開關(guan)觸點接觸不(bu)牢(lao)等造成(cheng)接觸電阻(zu)增(zeng)大，隨著時間增(zeng)長(chang)引起局部氧化，氧化后增(zeng)大了(le)接觸電阻(zu)。電流流過電阻(zu)時，會(hui)消耗電能產生熱量，導致過熱引起火災(zai)

（4）變壓器、電動機等設備運行故障(zhang)引起(qi)火(huo)災；變壓器長期過負(fu)荷運行或制造質量不(bu)良，造成線絕緣(yuan)損壞，匝間(jian)短路鐵芯渦流加大引起(qi)過熱(re)(re)，變壓器絕緣(yuan)油老化、擊穿(chuan)、發熱(re)(re)等引起(qi)火(huo)災或爆炸(zha)。

（5）電熱(re)設備(bei)、照(zhao)燈具使(shi)用(yong)不(bu)當引(yin)(yin)起(qi)火災；電爐等(deng)(deng)電熱(re)設備(bei)表面溫度很高(gao)，如使(shi)用(yong)不(bu)當會引(yin)(yin)起(qi)火大功率(lv)照(zhao)明燈具等(deng)(deng)與易燃(ran)物距(ju)離太近引(yin)(yin)起(qi)火災。

（6）電(dian)弧、電(dian)火(huo)(huo)(huo)花引(yin)(yin)起(qi)火(huo)(huo)(huo)災(zai)(zai)；電(dian)焊機、點焊機使用(yong)時電(dian)氣弧光、火(huo)(huo)(huo)花等會引(yin)(yin)燃(ran)周(zhou)圍物體，引(yin)(yin)起(qi)火(huo)(huo)(huo)災(zai)(zai)。施工現場由于電(dian)氣引(yin)(yin)發(fa)的火(huo)(huo)(huo)災(zai)(zai)原(yuan)因決(jue)不止以(yi)上幾點，這就要求用(yong)電(dian)人(ren)員(yuan)和(he)現場管理人(ren)員(yuan)認真執行(xing)操作規程，加強檢査，可以(yi)說(shuo)是可以(yi)預(yu)防(fang)的。
