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(guò)程，這種情況下可能建立電弧。又如線路絕緣水平嚴(yán)重下降，雷電產(chǎn)生的瞬態(tài)過(guò)電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過(guò)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)。

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)椤半姎饩€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(wú)因相對(duì)運(yùn)動(dòng)而產(chǎn)生的摩擦，電弧光保護(hù)維修，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)，對(duì)電氣線路將感應(yīng)瞬態(tài)過(guò)電壓”此時(shí)“芯線上感應(yīng)的瞬態(tài)過(guò)電壓是基本相同的而電纜梯架則因接地而為地電壓”所以，電弧光保護(hù)維修，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，電弧光保護(hù)維修。性?xún)r(jià)比高母線弧光保護(hù)，廠家直銷(xiāo)。電弧光保護(hù)維修</p><div
