弧光保護裝置是母線型弧光保護系統(tǒng)中的主要保護設(shè)備。主要用來檢測分析故障信號、接收分析采集單元的弧光故障信號，并對兩種信號進行綜合分析判斷。在滿足跳閘條件時，發(fā)出跳閘指令以便切除故障。一般安裝在進線柜或緊鄰進線柜的開關(guān)柜的二次控制門板上。其主要的技術(shù)優(yōu)勢有以下幾點： </p> <p> 1、動作迅速可靠。 </p> <p> 2、全數(shù)字化設(shè)計。 </p> <p> 3、保護原理簡單合理。 </p> <p> 4、故障信息記錄準確。 </p> <p> 5、多種輔助保護功能。 </p> <p> 6、強大的電氣性能。廣西弧光保護技術(shù)電弧光保護廠家直銷，可提供OEM，歡迎來電咨詢。</p><div style="width:100%;text-align: center;"><img

開關(guān)柜內(nèi)的發(fā)生短路弧光的功率可高達100MW，電弧燃燒所產(chǎn)生的能量與電弧的燃燒時間及短路電流變化值呈幾何倍增長，燃燒產(chǎn)生的高溫、高壓將會逐步摧毀元器件、銅排以及成列的開關(guān)柜，高明亮的弧光和有害氣體對人體也有巨大的傷害。如左圖的電弧光危害示意圖所示，保護裝置動作時間不能超過20ms，否則會產(chǎn)生不可修復的器件損壞，從而延長故障修復時間。電弧光的燃弧時間長短和對設(shè)備造成的損壞程度的評估如下所示 </p> <p> 35ms:沒有明顯損壞，一般可以在檢驗絕緣電阻后繼續(xù)投入使用 </p> <p> 100ms:損壞較小，在開關(guān)柜再次投入運行以前需要進行清潔或某些小的修理 </p> <p> 500ms：設(shè)備損壞嚴重，必須更換部分設(shè)備才可再次投入使用。 </p><p> 要考慮開關(guān)的接觸機構(gòu)是否存在故障，導致它在較大電流下形成飛弧短路或熱擊穿短路。（二）可能因素該開關(guān)動靜觸頭接觸方式為橫推插入式指夾雙面接觸，發(fā)生合閘彈跳重擊穿的概率很小。在這一點上遠優(yōu)于平面拍合式單面接觸方式。但是該開關(guān)動觸頭為雙斷點橋式壓簧片觸頭結(jié)構(gòu)，有12組動靜接觸點，接觸點多、連接點多，有可能發(fā)生以下故障：動觸頭連接虛；靜觸頭連接虛；加速機構(gòu)速度不夠；在動靜觸頭間已經(jīng)形成很大的接觸電阻；合閘時12組動靜接觸點不同步。（三）解體檢查我們對事故開關(guān)進行了解體檢查。檢查發(fā)現(xiàn)：12組動靜觸頭接觸面光滑干凈，顏色如初，觸頭上的導電膏依然如故。三相觸頭密封空間亦完好干凈。沒有發(fā)生強烈電弧所特有的燒熔、弧坑、炭化、變色、飛濺等痕跡。在動靜觸頭前端接觸面邊沿有微小的電火花灼蝕點，屬于正?，F(xiàn)象。前面考慮的五點故障因素，除加速機構(gòu)速度無法測量外，其余可以排除。圖7開關(guān)靜觸頭上黑色導電膏清晰可見圖8開關(guān)動觸頭光滑干凈顏色如初（四）結(jié)論：1.事故發(fā)生瞬間開關(guān)接通的電流基本在額定工作電流范圍內(nèi)（當然更在額定接通電流能力范圍內(nèi)）。定量估算可能為：I＝（80×4）×2＝320×2＝640A2.開關(guān)動靜觸頭的電氣結(jié)構(gòu)未發(fā)現(xiàn)異常。母線弧光保護專業(yè)設(shè)計生產(chǎn)，歡迎來電咨詢。</p><div

適用于電力開關(guān)柜中，引入電弧光保護裝置，可以捕捉到電氣弧光，并快速地切除故障點，保證電力系統(tǒng)的安全穩(wěn)定運行。 </p> <p> 主要特點 </p> <p> 1、動作迅速可靠 </p> <p> 采用了可靠的快速算法，可以在短時間內(nèi)判斷弧光變化信號和電流變化信號并迅速出口，從發(fā)現(xiàn)故障到出口跳閘時間間隔優(yōu)于10ms，確保開關(guān)柜內(nèi)設(shè)備的弧光在75ms以內(nèi)切除。 </p> <p> 2、全數(shù)字化設(shè)計 </p> <p> 本裝置采用全數(shù)字化設(shè)計，配置靈活，動作精度高，而且排除了由于旋鈕或其他機械設(shè)計導致的誤差***。 </p> <p> 3、保護原理簡單、合理 </p> <p> 根據(jù)弧光產(chǎn)生時的特點，裝置采用弧光和電流雙重判據(jù)，判據(jù)簡單且可以有效的保證動作的準確性。 </p> <p> 4、強大的電氣性能 </p> <p> 弧光探頭設(shè)計、連接線等全部采用耐高溫、阻燃的高分子材料，具有強大的電氣隔離效果。裝置完全光電式電弧光保護，廠家直銷，歡迎咨詢。襄陽弧光保護裝置型號</p><p style="text-indent:25px">易維護弧光保護，專業(yè)提供，歡迎來電咨詢。廣西弧光保護技術(shù)</p><p> 1.1 電弧光產(chǎn)生的原因 </p> <p> 引起開關(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、外來物體的進入、人為操作錯誤、系統(tǒng)改變或故障等。 </p> <p> 1.2 電弧光的能量 </p> <p> 開關(guān)柜發(fā)生內(nèi)部弧光故障產(chǎn)生的短路功率可高達8~60 MW，所產(chǎn)生的能量與電弧的燃燒時間、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**主要的因素是短路故障電流及電弧燃燒的時間，電弧能量與有關(guān)電弧燃燒的時間的關(guān)系如圖所示。從圖中可以看出，電弧燃燒持續(xù)時間超過100 ms ，所釋放的能量開始急劇增加，接著各種故障效應(yīng)對開關(guān)設(shè)備的電纜、銅排以及鋼材造成嚴重損壞. </p> <p> <br /> 廣西弧光保護技術(shù)</p><p
