主動(dòng)保護(hù)有以下兩種常見的可行的方法：1通過壓力傳感器進(jìn)行監(jiān)測(cè);2通過弧光傳感器進(jìn)行監(jiān)測(cè) </p> <p> <br /> </p> <p> 第一種方法（采用壓力傳感器作為電弧光探測(cè)單元）壓力波是裝置內(nèi)出現(xiàn)電弧故障的效應(yīng)之一，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(cè)壓力峰值。當(dāng)內(nèi)部的壓力達(dá)到設(shè)定值時(shí)，電弧監(jiān)測(cè)裝置發(fā)出動(dòng)作指令，控制開關(guān)器件動(dòng)作。但是要預(yù)先確定電弧在柜內(nèi)產(chǎn)生的過壓值并非易事。 </p> <p> <br /> </p> <p> 第二種方法（采用光纖傳感器作為電弧光探測(cè)單元）弧光監(jiān)測(cè)器的操作邏輯如下：電弧現(xiàn)象會(huì)產(chǎn)生強(qiáng)烈的光輻射，因此柜體內(nèi)出現(xiàn)的弧光可以被弧光傳感器探測(cè)到當(dāng)弧光監(jiān)控系統(tǒng)探測(cè)到故障，會(huì)發(fā)出動(dòng)作信號(hào)給斷路器。這種方法的探測(cè)反應(yīng)時(shí)間*為1毫秒?；」鈧鞲衅鞣譃榭煞譃殡娏餍秃凸饫w性（可見光和紫外光）其中支持可見光的弧光傳感器有基頓電氣JD9900B系列弧光傳感器。

廠用/配電中壓開關(guān)柜為全廠輔機(jī)/供電系統(tǒng)的供電樞紐。在發(fā)生內(nèi)部故障時(shí)，是否能迅速地切除故障，對(duì)全廠/配電系統(tǒng)的安全運(yùn)行至關(guān)重要。但是，按目前的保護(hù)方案，存在以下幾個(gè)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(shí)的級(jí)差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護(hù)的配合級(jí)差更是長(zhǎng)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(shí)切除。換句話說，現(xiàn)有的廠用中壓母線能在早時(shí)間切除故障的保護(hù)還是個(gè)空白?？墒?，我們只要稍加注意，就會(huì)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(shí)切除，都是我們極為不愿意看到的狀況。因?yàn)殚_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(shí)間內(nèi)達(dá)到頂峰，嚴(yán)重危及人身和設(shè)備安全。母線弧光保護(hù)廠家直銷。母線弧光保護(hù)**</p><p

</p> <p> <br /> </p> <p> 什么是弧光放電？ </p> <p> <br /> </p> <p> 當(dāng)兩電極間電壓升高時(shí)，電極**近處空氣中的正負(fù)離子被電場(chǎng)加速，移動(dòng)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(shí)，溫度隨之急劇上升產(chǎn)生電弧，這種放電稱為弧光放電。弧光放電一般不需要很高的電壓，屬于低電壓大電流放電。 </p> <p> <br /> </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(huì)消失。 </p> <p> <br /> </p> <p> 電弧光是怎樣形成的 </p> <p> <br /> </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(zhǎng)的電弧只需20V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> <p> <br /> 秦皇島弧光保護(hù)模塊</p><p
