壓縮階段:電弧占據(jù)了整個(gè)空氣空間，由于持續(xù)的釋放能量產(chǎn)生過(guò)熱，導(dǎo)致對(duì)流和輻射，保留在柜內(nèi)的空氣被加熱，在整個(gè)初級(jí)階段不同區(qū)域的溫度和壓力值不一樣。 </p> <p> 擴(kuò)展階段:從這一瞬間開(kāi)始，內(nèi)部壓力增加，由于過(guò)熱的空氣開(kāi)始流動(dòng)而形成一個(gè)空洞。在這個(gè)階段其壓力達(dá)到比較大值，并因?yàn)闊峥諝獾尼尫哦_(kāi)始減弱。 </p> <p> 發(fā)射階段:由于電弧能量的持續(xù)釋放，幾乎所有的空氣均被一個(gè)緩和但恒定的壓力擠壓出去。 </p> <p> 發(fā)熱階段:在驅(qū)逐出空氣后，柜內(nèi)的溫度幾乎達(dá)到電弧的溫度。***階段就由此開(kāi)始，直至熄滅。此時(shí)，所有金屬和絕緣體在受到產(chǎn)生的氣體、霧和溶蝕物質(zhì)顆粒的侵蝕后，已融為一體了。 </p> <p> 當(dāng)電弧出現(xiàn)在非常封閉的設(shè)備環(huán)境時(shí)，可能不會(huì)出現(xiàn)上述某些階段或者只有較少的影響;然而，在電弧的周圍，會(huì)形成壓力波、并導(dǎo)致溫度的上升。各種弧光保護(hù)廠家直銷。</p><div style="width:100%;text-align: center;"><img style="max-width:

中、低壓母線在發(fā)生短路故障、運(yùn)行人員誤操作和誤入帶電間隔等原因產(chǎn)生的電弧光對(duì)設(shè)備及人員造成的危害極大。電弧光使開(kāi)關(guān)設(shè)備內(nèi)的壓力和溫度迅速升高，如不及時(shí)切除，容易造成電纜護(hù)套著火和母線熔毀，并且產(chǎn)生大量有害氣體傷害呼吸系統(tǒng)、高溫灼傷皮膚和刺傷眼睛。短路故障時(shí)，開(kāi)關(guān)設(shè)備劇烈震動(dòng)使固定件松動(dòng)脫落、甚至導(dǎo)致開(kāi)關(guān)柜造成人員傷亡。中低壓母線系統(tǒng)中一般不配置**的快速母線保護(hù)，而是依賴上一級(jí)的后備過(guò)流保護(hù)切除母線故障，過(guò)流保護(hù)有延時(shí)，這就導(dǎo)致故障切除時(shí)間較長(zhǎng)，增加了設(shè)備的損害程度。電弧光保護(hù)系統(tǒng)原理簡(jiǎn)單、動(dòng)作迅速可靠，能夠有效減輕電弧光對(duì)設(shè)備和人身的傷害。電弧光保護(hù)裝置廠家直銷，歡迎來(lái)電咨詢。高壓弧光保護(hù)多少錢(qián)</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(guò)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(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?！薄半娀⌒远搪返钠鸹鹞ｋU(xiǎn)遠(yuǎn)大于上述金屬性短路的起火危險(xiǎn)?！?濮陽(yáng)弧光保護(hù)裝置</p><p
