</p> <p> 弧光保護(hù)裝置工作原理，就是檢測(cè)弧光和過(guò)流。突破了常規(guī)保護(hù)的判據(jù)原則，率先采用了檢測(cè)弧光和電流兩個(gè)非關(guān)聯(lián)參數(shù)作為判據(jù)比其他保護(hù)誤動(dòng)率更小，可靠性更高。弧光采集單元與主控單元配合使用，是弧光保護(hù)裝置的重要組成部分，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。弧光采集單元通常安裝在選定的開(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。孝感弧光保護(hù)公司高壓弧光保護(hù)專(zhuān)家，廠家直銷(xiāo)，歡迎來(lái)電咨詢(xún)。</p><div

引起開(kāi)關(guān)柜弧光短路故障的原因很多，主要有：絕緣故障、載流回路不良、外來(lái)物體的進(jìn)入、人為操作錯(cuò)誤、系統(tǒng)改變或故障等。 </p> <p> 1.2 電弧光的能量 </p> <p> 開(kāi)關(guān)柜發(fā)生內(nèi)部弧光故障產(chǎn)生的短路功率可高達(dá)8~60 MW，所產(chǎn)生的能量與電弧的燃燒時(shí)間、短路電流的平方值、柜體幾何尺寸以及所使用的材料等因素有關(guān)，其中最主要的因素是短路故障電流及電弧燃燒的時(shí)間，電弧能量與有關(guān)電弧燃燒的時(shí)間的關(guān)系如圖所示。從圖中可以看出，電弧燃燒持續(xù)時(shí)間超過(guò)100 ms ，所釋放的能量開(kāi)始急劇增加，接著各種故障效應(yīng)對(duì)開(kāi)關(guān)設(shè)備的電纜、銅排以及鋼材造成嚴(yán)重?fù)p壞. </p> <p> <br /> </p><p> 什么是弧光放電？ </p> <p> 當(dāng)兩電極間電壓升高時(shí)，在電極最近處空氣中的正負(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(chēng)為“電離”?？諝獗浑婋x的同時(shí)，溫度隨之急劇上升產(chǎn)生電弧，這種放電稱(chēng)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> 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> <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，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> 弧光保護(hù)裝置，廠家直銷(xiāo)，全國(guó)招商，可提供OEM。</p><div style="width:100%;text-align:
