style="text-indent:25px">電弧光保護(hù)系統(tǒng)可以在開關(guān)柜發(fā)生弧光故障的時(shí)候，保護(hù)操作人員不受傷害，并且降低財(cái)產(chǎn)損失程度。當(dāng)出現(xiàn)弧光時(shí)候，弧光以 300m/s 的速度爆發(fā)，摧毀途中的任何物質(zhì).。只要系統(tǒng)中不斷電，弧光就會(huì)一直存在。要想比較大限度的減少弧光的危害，我們需要一種安全、迅速而有效的半導(dǎo)體電弧光保護(hù)系統(tǒng)。在開關(guān)柜抽屜內(nèi)，弧光可以迅速的在 10ms內(nèi)達(dá)到 3m遠(yuǎn)，因此要想很大程度降低損失，時(shí)間是個(gè)**主要的因素。KEATON電弧光保護(hù)系統(tǒng)輸出跳閘信號(hào)時(shí)間極短，即使在安裝或者維護(hù)的時(shí)候也能保護(hù)操作人員的安全。</p><div style="width:100%;text-align: center;"><img style="max-width:

國(guó)產(chǎn)的弧光保護(hù)比進(jìn)口的更適用，國(guó)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(guó)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。
