擴(kuò)展階段:從這一瞬間開始，內(nèi)部壓力增加，由于過熱的空氣開始流動(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_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。 </p><p> 國產(chǎn)的弧光保護(hù)比進(jìn)口的更適用，國產(chǎn)的把主控單元、電流單元和copy弧光采集單元集成在一起，安裝方便，可靠性高，進(jìn)口的分幾個(gè)單元主要是為了自己的利益。其實(shí)UTU和RIZNER兩個(gè)產(chǎn)品實(shí)質(zhì)上是一樣的，面板不同而已。 </p> <p> 目前南京、保定的生產(chǎn)廠家都是采用一體式的裝置，只有早起仿ABB、VAMP、UTU的廠家按照進(jìn)口產(chǎn)品的結(jié)構(gòu)模式做的，各個(gè)單元之間通過電纜連接，人為增加了節(jié)點(diǎn)，反而降低了設(shè)備的可靠性。zhidao </p> <p> 弧光保護(hù)的技術(shù)發(fā)源地在芬蘭。ABB的REA系列，Vamp的321,221系列，在國內(nèi)都有比較多的應(yīng)用，還有Arcteq、UTU 也都有較成熟的弧光保護(hù)產(chǎn)品。 </p> <p> 電弧是放電過程中發(fā)生的一種現(xiàn)象，當(dāng)兩點(diǎn)之間的電壓超過其工頻絕緣強(qiáng)度極限時(shí)就會(huì)發(fā)生。當(dāng)適當(dāng)?shù)臈l件出現(xiàn)時(shí)，一個(gè)攜帶著電流的等離子產(chǎn)生，直到電源側(cè)的保護(hù)設(shè)備斷開才會(huì)消失?？諝庠谕ǔl件是很好的絕緣體，但由于溫度的升高或者其他外部因素的作用，其化學(xué)和物理特性發(fā)生改變時(shí)，它可能變成通電的導(dǎo)體。弧光保護(hù)裝置，可護(hù)展。</p><div
