當(dāng)兩電極間電壓升高時(shí)，在電極**近處空氣中的正負(fù)離子被電場(chǎng)加速，在移動(dòng)的過(guò)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，煙臺(tái)弧光保護(hù)系統(tǒng)，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，煙臺(tái)弧光保護(hù)系統(tǒng)，電弧將會(huì)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(kāi)建立了電弧，則維持此10mm 長(zhǎng)的電弧只需20V 的電壓。也就是說(shuō)只要先接觸，煙臺(tái)弧光保護(hù)系統(tǒng)，之后又分開(kāi)，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>

1）弧光保護(hù)主控單元：主單元為電弧光保護(hù)系統(tǒng)的控制中心，收集動(dòng)作信號(hào)并對(duì)收集的數(shù)據(jù)進(jìn)行處理、判斷、發(fā)出跳閘信號(hào)以切除故障。設(shè)備自帶四路輸出接口分別為弧光跳閘出口1、弧光跳閘出口2、弧光跳閘出口3、跳閘總出口4。設(shè)備支持ModBUS-RTU規(guī)約，可通過(guò)后臺(tái)對(duì)設(shè)備進(jìn)行參數(shù)設(shè)置、實(shí)時(shí)數(shù)據(jù)讀取、故障信息讀取、復(fù)歸等操作，方便組網(wǎng)運(yùn)行。 </p> <p> 2）采集單元：弧光采集單元與主控單元配合使用，是弧光保護(hù)系統(tǒng)的重要組成部分，主要用于采集故障弧光，并將判斷后的結(jié)果通過(guò)光信號(hào)傳遞給主控單元。單個(gè)弧光采集單元可以安裝,16個(gè)弧光探頭，根據(jù)系統(tǒng)的大小可以任意增減弧光采集單元的數(shù)量?；」獠杉瘑卧ǔ０惭b在選定的開(kāi)關(guān)柜內(nèi)中，選擇的原則是保證該單元相關(guān)光纖用量盡量少。

3）弧光傳感器：專門用于故障弧光采集，是無(wú)源的弧光探測(cè)傳感器，安裝在開(kāi)關(guān)柜的母線室內(nèi)或饋線柜內(nèi)電氣元件的連接處。當(dāng)發(fā)生弧光故障時(shí)，光照度大幅度增加，弧光傳感器直接將光信號(hào)傳給弧光采集單元或饋線保護(hù)單元。弧光保護(hù)裝置專業(yè)銷售。綿陽(yáng)弧光保護(hù)分類</p><p

有人提倡在低壓柜內(nèi)安裝弧光保護(hù)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(cè)到弧光信號(hào)，動(dòng)作于低壓斷路器，時(shí)間會(huì)比傳統(tǒng)的通過(guò)檢測(cè)電流信號(hào)動(dòng)作于低壓斷路器短，這樣的說(shuō)法有道理嗎？低壓柜內(nèi)與中壓柜內(nèi)安裝弧光保護(hù)裝置有何區(qū)別呢？先聽(tīng)聽(tīng)大家怎么看，稍后我也會(huì)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(dòng)作時(shí)間是否能保證在***擴(kuò)大前切除電源？這個(gè)不清楚 </p> <p> -----這個(gè)有時(shí)間可以保證，而且這個(gè)時(shí)間確實(shí)很短，一般廠家通過(guò)實(shí)際驗(yàn)證后給出斷路器與弧光保護(hù)裝置在故障情況下動(dòng)作的時(shí)間； </p> <p> 2、圖中是固定分割或抽屜柜，安裝在動(dòng)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(cè)，抽屜或分隔內(nèi)和饋出線側(cè)發(fā)生的弧光短路***也無(wú)法及時(shí)切斷電源。這種檢測(cè)方式適用于固定柜。 </p> <p> ----弧光傳感器**合適的位置我認(rèn)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(kāi)關(guān)以防止***擴(kuò)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(gè)回路發(fā)生，傳感器的檢測(cè)會(huì)不會(huì)誤動(dòng)作，跳閘沒(méi)有發(fā)生故障的回路；
