電弧光保護系統(tǒng)具備傳統(tǒng)低壓保護裝置的許多功能，并能夠記錄故障事件和波形，從而為故障的分析提供重要的基礎(chǔ)數(shù)據(jù)。電弧光保護是一種快速可靠的**母線保護系統(tǒng)，采用檢測弧光和過流雙判據(jù)原理，具有原理簡單、動作可靠迅速、對變電站一次設(shè)備無特殊要求、適應(yīng)于各種運行方式、且在各種運行方式下保護不需要切換等優(yōu)點，為目前發(fā)電廠、變電站、工業(yè)及商業(yè)配電系統(tǒng)母線保護理想的解決方案。 </p> <p> <br /> </p> <p> 什么是弧光放電？ </p> <p> <br /> </p> <p> 當兩電極間電壓升高時，電極**近處空氣中的正負離子被電場加速，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> <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，天津弧光保護仿真，天津弧光保護仿真、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電，天津弧光保護仿真。 </p> <p> <br />

有人提倡在低壓柜內(nèi)安裝弧光保護裝置，低壓柜內(nèi)一旦發(fā)生短路故障，弧光傳感器能立馬檢測到弧光信號，動作于低壓斷路器，時間會比傳統(tǒng)的通過檢測電流信號動作于低壓斷路器短，這樣的說法有道理嗎？低壓柜內(nèi)與中壓柜內(nèi)安裝弧光保護裝置有何區(qū)別呢？先聽聽大家怎么看，稍后我也會給出我的看法 </p> <p> <br /> </p> <p> 本帖***由 bzp4891 于 2016-5-19 12:02 編輯 </p> <p> 1、首先動作時間是否能保證在***擴大前切除電源？這個不清楚 </p> <p> -----這個有時間可以保證，而且這個時間確實很短，一般廠家通過實際驗證后給出斷路器與弧光保護裝置在故障情況下動作的時間； </p> <p> 2、圖中是固定分割或抽屜柜，安裝在動力電纜室內(nèi)？這里發(fā)生短路的幾率很小，除非連接不可靠，端子布置不合理，按照這種檢測，抽屜或分隔內(nèi)和饋出線側(cè)發(fā)生的弧光短路***也無法及時切斷電源。這種檢測方式適用于固定柜。 </p> <p> ----弧光傳感器**合適的位置我認為在主母線室內(nèi)，用于主母線發(fā)生短路故障情況下切斷主開關(guān)以防止***擴大化，如果非要安裝在饋線柜例如抽屜柜或固定分隔柜的電纜室，一是安裝的傳感器的數(shù)量很多成本難以承受，二是如果抽屜回路的某一個回路發(fā)生，傳感器的檢測會不會誤動作，跳閘沒有發(fā)生故障的回路； </p> <p> <br /> </p><p

弧光保護動作時間主要由兩部分組成：裝置動作時間和開關(guān)動作時間。弧光保護裝置的動作時間根據(jù)各廠商的動作原理不同（光電探頭或光纖探頭等）一般在1~10毫秒，開關(guān)動作時間（參考GE公司VB1—13.8真空斷路器）一般在50~60毫秒。故電弧光保護動作時間小于開關(guān)柜電弧耐受時間，不會對開關(guān)柜造成嚴重損傷。<p
