在柜體內形成電弧的過程可分為四個階段: </p> <p> 壓縮階段:電弧占據(jù)了整個空氣空間，由于持續(xù)的釋放能量產(chǎn)生過熱，導致對流和輻射，保留在柜內的空氣被加熱，在整個初級階段不同區(qū)域的溫度和壓力值不一樣。 </p> <p> 擴展階段:從這一瞬間開始，內部壓力增加，由于過熱的空氣開始流動而形成一個空洞。在這個階段其壓力達到比較大值，并因為熱空氣的釋放而開始減弱。 </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緩和但恒定的壓力擠壓出去。 </p> <p> 發(fā)熱階段:在驅逐出空氣后，柜內的溫度幾乎達到電弧的溫度。***階段就由此開始，直至熄滅。此時，所有金屬和絕緣體在受到產(chǎn)生的氣體、霧和溶蝕物質顆粒的侵蝕后，已融為一體了。 </p> <p> 當電弧出現(xiàn)在非常封閉的設備環(huán)境時，可能不會出現(xiàn)上述某些階段或者只有較少的影響;然而，在電弧的周圍，會形成壓力波、并導致溫度的上升。 </p><p> 主動保護有以下兩種常見的、可行的方法: </p> <p> 1) 通過壓力傳感器進行監(jiān)測 </p> <p> 2) 通過弧光傳感器進行監(jiān)測 </p> <p> 第一種方法(采用壓力傳感器作為電弧光探測單元) </p> <p> 壓力波是裝置內出現(xiàn)電弧***的效應之一，它將在電弧出現(xiàn)后的10-15毫秒后出現(xiàn)，可以安裝一些壓力傳感器用于探測壓力峰值。當內部的壓力達到設定值時，電弧監(jiān)測裝置發(fā)出動作指令，控制開關器件動作。但是要預先確定電弧在柜內產(chǎn)生的過壓值并非易事。 </p> <p> 第二種方法(采用光纖傳感器作為電弧光探測單元) </p> <p> 弧光監(jiān)測器的操作邏輯如下:電弧現(xiàn)象會產(chǎn)生強烈的光輻射，因此柜體內出現(xiàn)的弧光可以被弧光傳感器探測到。當弧光監(jiān)控系統(tǒng)探測到故障，會發(fā)出動作信號給斷路器。這種方法的探測反應時間*為1毫秒。工業(yè)用弧光保護裝置，專業(yè)提供。</p><div

加上斷路器動作時間，差動保護和無時限電流速斷保護動作，故障切除時間約100ms。即使電流速斷保護比弧光保護多40ms,查看弧光危害示意圖，電纜已經(jīng)燃燒。如果是帶時限電流速斷保護延時100ms、過電流Ⅰ段延時300ms,已經(jīng)達到柜體燃燒甚至的可能。弧光保護生產(chǎn)廠家，歡迎來電咨詢。數(shù)字化弧光保護電源</p><p

中壓母線尚沒有配置任何專門的保護; 而是由進線開關的相關后備保護來兼顧的; </p> <p> ② 進線開關與出線開關的保護需要相互配合:一般速斷保護延時的級差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護的配合級差更是長達1 – 2秒。 </p> <p> 所以，廠用/配電系統(tǒng)中壓母線上所發(fā)生的任何故障都至少要延時切除。換句話說，現(xiàn)有的廠用中壓母線能在**早時間切除故障的保護還是個空白?？墒?，我們只要稍加注意，就會不難發(fā)現(xiàn)不論是中壓開關母線的上游還是下游的諸多電氣設備無一沒有配有快速保護。相比之下，我們恐怕很難有充分的理由來說明，中壓母線的安全性可靠性應該受到這樣的懈怠。鑒于中壓母線的重要地位，任何故障的延時切除，都是我們極為不愿意看到的狀況。因為開關柜內的各種故障，其短路電流所產(chǎn)生的電弧及其大量的高溫，使柜內氣體急劇膨脹，可在極短的時間內達到頂峰，嚴重危及人身和設備安全。
