電弧性短路起火：如將兩電極接觸后再拉開建立了電弧，則維持此10mm 長的電弧只需20V 的電壓。也就是說只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導(dǎo)體間的電弧、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電。 </p> <p> 帶電導(dǎo)體間的電弧性短路起火：短路起火時(shí)有兩種可能，其一是兩導(dǎo)體（如相線與中性線）接觸時(shí)因短路電流產(chǎn)生的高溫，使接觸點(diǎn)金屬熔化，之后金屬熔化成團(tuán)收縮而脫離接觸的過程，在這種情況下可能建立電弧?！坝秩缇€路絕緣水平嚴(yán)重下降，雷電產(chǎn)生的瞬態(tài)過電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過電壓都可能擊穿劣化的線路絕緣而建立電弧。”“電弧性短路的起火危險(xiǎn)遠(yuǎn)大于上述金屬性短路的起火危險(xiǎn)。” </p><p> 接地故障電弧起火：由于“接地故障發(fā)生的幾率遠(yuǎn)大于帶電導(dǎo)體間的短路”，所以“接地故障電弧引起的火災(zāi)遠(yuǎn)多于帶電導(dǎo)體間的電弧火災(zāi)”。這是因?yàn)椤霸陔姎饩€路施工中，穿鋼管拉電線時(shí)帶電導(dǎo)體絕緣外皮之間并無因相對(duì)運(yùn)動(dòng)而產(chǎn)生的摩擦，但帶電導(dǎo)體絕緣外皮與鋼管間的摩擦卻使絕緣摩薄或受損。另外，發(fā)生雷擊時(shí)地面上出現(xiàn)瞬變電磁場(chǎng)，它對(duì)電氣線路將感應(yīng)瞬態(tài)過電壓”，此時(shí)“芯線上感應(yīng)的瞬態(tài)過電壓是基本相同的，而電纜梯架則因接地而為地電壓”，所以，芯線對(duì)地的電位差較大。從摩損和電位差大兩方面分析，接地故障電弧起火率自然偏高。 </p> <p> 爬電起火：爬電是指電弧不是建立在空氣間隙中的電弧，而是出現(xiàn)在設(shè)備絕緣表面上的電弧。例如電源插頭的絕緣表面上的一個(gè)或多個(gè)相線插腳和PE線插腳，它們之間的絕緣表面可能發(fā)生爬電。電弧光保護(hù)裝置廠家直銷，歡迎來電咨詢。</p><div style="width:100%;text-align: center;"><img
