當(dāng)兩電極間電壓升高時，在電極**近處空氣中的正負(fù)離子被電場加速，在移動的過程中與其它空氣分子碰撞產(chǎn)生新的離子，這種離子大量增加的現(xiàn)象稱為“電離”。空氣被電離的同時，溫度隨之急劇上升產(chǎn)生電弧，這種放電稱為弧光放電?；」夥烹娨话悴恍枰芨叩碾妷?，屬于低電壓大電流放電。 </p> <p> 弧光放電產(chǎn)生的條件是小間隙和大電流，如果增加間隙或減小電流，電弧將會消失。 </p> <p> <p> 電弧光是怎樣形成的？ </p> <p> 電弧性短路起火：如將兩電極接觸后再拉開建立了電弧，則維持此10mm 長的電弧只需20V 的電壓。也就是說只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導(dǎo)體間的電弧、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電。 </p> 焦作弧光保護(hù)生產(chǎn)廠家電弧光保護(hù)專業(yè)生產(chǎn)，性能穩(wěn)定，歡迎來電咨詢。</p><div

廠用/配電中壓開關(guān)柜為全廠輔機/供電系統(tǒng)的供電樞紐。在發(fā)生內(nèi)部故障時，是否能迅速地切除故障，對全廠/配電系統(tǒng)的安全運行至關(guān)重要。但是，按目前的保護(hù)方案，存在以下幾個問題： </p> <p> ① 中壓母線尚沒有配置任何專門的保護(hù); 而是由進(jìn)線開關(guān)的相關(guān)后備保護(hù)來兼顧的; </p> <p> ② 進(jìn)線開關(guān)與出線開關(guān)的保護(hù)需要相互配合:一般速斷保護(hù)延時的級差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護(hù)的配合級差更是長達(dá)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(hù)還是個空白。可是，我們只要稍加注意，就會不難發(fā)現(xiàn)不論是中壓開關(guān)母線的上游還是下游的諸多電氣設(shè)備無一沒有配有快速保護(hù)。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(yīng)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(guān)柜內(nèi)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(nèi)氣體急劇膨脹，可在極短的時間內(nèi)達(dá)到頂峰，嚴(yán)重危及人身和設(shè)備安全。 </p> <p> <br /> </p><p style="text-indent:25px">電弧光保護(hù)裝置分為饋線電弧光保護(hù)和母線電弧光保護(hù)、主要用于保護(hù)重點設(shè)備和相關(guān)工作人員的生命安全。在以前，由于技術(shù)還不是特別成熟、考慮也不是特別周全、我國的大部分中、低壓母線沒有裝設(shè)快速的母線保護(hù)，只是采用了簡單的消弧裝置和變壓器后備保護(hù)。這些保護(hù)存在動作速度慢、故障切除時間長等缺點，嚴(yán)重的影響了整個電網(wǎng)的安全運行。而電弧光保護(hù)裝置就是專門為解決這些問題而誕生的繼電保護(hù)設(shè)備。我公司生產(chǎn)的電弧光保護(hù)裝置適用于110KV、66KV、35KV 、10KV及0.4KV的電壓等級，既可以分散在開關(guān)柜就地安裝，也可以集中組屏安裝，提供以太網(wǎng)、RS485通訊接口，可以和其它保護(hù)、自動化設(shè)備一起，通過通信接口組成自動化系統(tǒng)?；」獗Ｗo(hù)裝置設(shè)計**，歡迎來電咨詢。</p><div style="width:100%;text-align: center;"><img

</p> <p> 跳閘回路采用了快速繼電器技術(shù)，確保保護(hù)系統(tǒng)在1ms內(nèi)發(fā)出跳閘信號，加上斷路器動作時間(35-60ms)，使開關(guān)柜內(nèi)部電弧光故障總切除時間控制在60ms以內(nèi)，而且在外觀上無明顯損壞。繼電保護(hù)裝置包括測量、計算、自檢、動作等時間累計約44ms, 加上斷路器動作時間，差動保護(hù)和無時限電流速斷保護(hù)動作，故障切除時間約100ms。即使電流速斷保護(hù)比弧光保護(hù)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(hù)延時100ms、過電流Ⅰ段延時300ms,已經(jīng)達(dá)到柜體燃燒甚至的可能。弧光保護(hù)裝置，可護(hù)展。焦作弧光保護(hù)生產(chǎn)廠家</p><p

綜上，兩個設(shè)備保護(hù)的對象和作用完全不同。消弧柜針對饋線，弧光保護(hù)針對母線。消弧裝置為了保證供電設(shè)備正常運行，而母線弧光保護(hù)系統(tǒng)是在供電系統(tǒng)發(fā)生弧光故障時，可以在100ms內(nèi)切除故障，比較大限度的保護(hù)人身安全并減少財產(chǎn)損失。河北弧光保護(hù)模塊</p><p
