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; 而是由進線開關(guān)的相關(guān)后備保護來兼顧的; </p> <p> ② 進線開關(guān)與出線開關(guān)的保護需要相互配合:一般速斷保護延時的級差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護的配合級差更是長達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還是個空白?？墒?，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備無一沒有配有快速保護，煙臺弧光保護系統(tǒng)。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，煙臺弧光保護系統(tǒng)，煙臺弧光保護系統(tǒng)，可在極短的時間內(nèi)達到頂峰，嚴重危及人身和設備安全。

帶電導體間的電弧性短路起火：短路起火時有兩種可能，其一是兩導體（如相線與中性線）接觸時因短路電流產(chǎn)生的高溫，使接觸點金屬熔化，之后金屬熔化成團收縮而脫離接觸的過程，這種情況下可能建立電弧。又如線路絕緣水平嚴重下降，雷電產(chǎn)生的瞬態(tài)過電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過電壓都可能擊穿劣化的線路絕緣而建立電弧。電弧性短路的起火危險遠大于上述金屬性短路的起火危險。 </p> <p> <br /> </p> <p> 接地故障電弧起火：由于接地故障發(fā)生的幾率遠大于帶電導體間的短路”所以“接地故障電弧引起的火災遠多于帶電導體間的電弧火災”這是因為“電氣線路施工中，穿鋼管拉電線時帶電導體絕緣外皮之間并無因相對運動而產(chǎn)生的摩擦，但帶電導體絕緣外皮與鋼管間的摩擦卻使絕緣摩薄或受損。另外，發(fā)生雷擊時地面上出現(xiàn)瞬變電磁場，對電氣線路將感應瞬態(tài)過電壓”此時“芯線上感應的瞬態(tài)過電壓是基本相同的而電纜梯架則因接地而為地電壓”所以，芯線對地的電位差較大。從摩損和電位差大兩方面分析，接地故障電弧起火率自然偏高。滄州弧光保護采購性價比高，弧光保護全國招商。</p><div

IEC298《交流金屬封閉開關(guān)設備與控制設備》附錄AA中規(guī)定的內(nèi)部燃弧測試時間是0.1秒。目前市場上銷售的開關(guān)柜基本上是按照IEC298標準生產(chǎn)的，也就是說開關(guān)柜可以承受的電弧燃燒時間為0.1秒。 </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?；」獗Ｗo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> 主動保護有以下兩種常見的可行的方法：1通過壓力傳感器進行監(jiān)測;2通過弧光傳感器進行監(jiān)測 </p> <p> <br /> </p> <p> 第一種方法（采用壓力傳感器作為電弧光探測單元）壓力波是裝置內(nèi)出現(xiàn)電弧故障的效應之一，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壓力峰值。當內(nèi)部的壓力達到設定值時，電弧監(jiān)測裝置發(fā)出動作指令，控制開關(guān)器件動作。但是要預先確定電弧在柜內(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單元）弧光監(jiān)測器的操作邏輯如下：電弧現(xiàn)象會產(chǎn)生強烈的光輻射，因此柜體內(nèi)出現(xiàn)的弧光可以被弧光傳感器探測到當弧光監(jiān)控系統(tǒng)探測到故障，會發(fā)出動作信號給斷路器。這種方法的探測反應時間*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。電弧光保護廠家直銷，可提供OEM，歡迎來電咨詢。</p><div

3、避免變壓器因近距離母線故障造成動穩(wěn)定破壞，延長變壓器的使用壽命。 </p> <p> 4、縮短電弧光故障切除時間，避免波及站內(nèi)直流系統(tǒng)造成重大損失。 </p> <p> 5、減少因電弧光故障造成設備停運的時屬間，更快地恢復供電。 </p> <p> 主要應用于以下場合 </p> <p> 1、電力變電站。 </p> <p> 2、火電廠電氣段開關(guān)柜母線室及饋線柜。 </p> <p> 3、風電場升壓站集電線路開關(guān)柜。 </p> <p> 4、箱式變電站。電弧光保護裝置源頭廠家。襄陽弧光保護優(yōu)點</p><p style="text-indent:25px">光電式電弧光保護，廠家直銷，歡迎咨詢。煙臺弧光保護系統(tǒng)</p><p> 電弧光保護目的是在發(fā)生電弧故障時，通過限制電弧燃燒時間來保護附近工作人員及設備。電弧保護首先必須檢測故障電弧，然后才能切斷流過的故障電流。在中低開關(guān)柜內(nèi)部故障保護中，一般是通過跳開斷路器來切除故障使故障電弧熄滅。電弧燃燒時伴隨著光、聲及電磁波形式的輻射。通過分析可見光、聲波、紅外線或無線電頻率的輻射可以檢測到電弧的存在，甚至連由電弧產(chǎn)生的壓力波也已經(jīng)用來檢測它的存在。然而，*****使用的方法還是通過檢測可見光來實現(xiàn)。 </p> <p>
