電弧光保護(hù)系統(tǒng)使用先進(jìn)的處理器技術(shù)來控制系統(tǒng)的功能。該處理器技術(shù)也使得電弧光保護(hù)系統(tǒng)功能的編程，可匹配開關(guān)柜的不同運行方式。在跳閘回路里采用的半導(dǎo)體技術(shù)（可控硅開關(guān)）確保了開關(guān)柜里的供電開關(guān)以**小的延時得到跳閘信號。在不論是KEATON電弧光保護(hù)系統(tǒng)的主控單元，還是電弧光單元探測到電弧光，并且電流單元的整定的電流定值被超過，電弧光保護(hù)系統(tǒng)的跳閘信號將在極短時間內(nèi)到達(dá)供電開關(guān)。 </p> <p> 電流的信息也可直接取自安全電流回路，在此情況下，電弧光保護(hù)也可盡可能快的得到過流的信息。如果偶爾光線信號超過光線設(shè)定值或者電流信號超過電流設(shè)定值，系統(tǒng)不會輸出跳閘信號，也不會記憶在跳閘回路中，但是在主控單元上會顯示報警信號。在編程的時候，需要考慮系統(tǒng)按照用戶所希望的方式正常工作。采用光纖技術(shù)來向主控單元傳輸跳閘信號，確保了電弧光保護(hù)系統(tǒng)的完美功能，它的抗干擾能力強，跳閘信號可以非常迅速的輸出到斷路器。 </p><p> 開關(guān)柜內(nèi)的發(fā)生短路弧光的功率可高達(dá)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(hù)裝置動作時間不能超過20ms，否則會產(chǎn)生不可修復(fù)的器件損壞，從而延長故障修復(fù)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(jìn)行清潔或某些小的修理 </p> <p> 500ms：設(shè)備損壞嚴(yán)重，必須更換部分設(shè)備才可再次投入使用。紫外光弧光保護(hù)探頭，專業(yè)生產(chǎn)。</p><div

而為什么其他母線保護(hù)的動作時間那么長，因為“保護(hù)配合”。電弧光保護(hù)只要滿足“電弧”和“過流”等判據(jù)就可立即發(fā)出跳閘指令。而其他母線保護(hù)（參考西門子公司7SD和7SJ62綜保裝置）當(dāng)滿足“過流”判據(jù)后還必須等待下級負(fù)載的“無過流匯報”后才可以發(fā)出跳閘指令。因為下級負(fù)載短路和母線短路都會造成進(jìn)線開關(guān)“過流”，如果下級負(fù)載短路應(yīng)該讓下級負(fù)載開關(guān)來切除，母線短路則由母線進(jìn)線開關(guān)來切除。電弧光保護(hù)猶如手持尚方寶劍，而其他母線保護(hù)則就像一個團隊，不敢輕舉妄動。 </p> <p> 總上所述，采用電弧光母線保護(hù)可以在現(xiàn)有開關(guān)柜的電弧耐受時間標(biāo)準(zhǔn)以內(nèi)切除弧光短路故障，從而比較大限度地保護(hù)了附近工作人員，使開關(guān)裝置等配電設(shè)備免受損壞，很大減少了設(shè)備維修費用及維修故障所需的停電時間，因而具有明顯的經(jīng)濟效益，為理想的中壓母線保護(hù)解決方案。母線弧光保護(hù)專業(yè)設(shè)計生產(chǎn)，歡迎來電咨詢。重慶弧光保護(hù)測控</p><p

接地故障電弧起火：由于“接地故障發(fā)生的幾率遠(yuǎn)大于帶電導(dǎo)體間的短路”，所以“接地故障電弧引起的火災(zāi)遠(yuǎn)多于帶電導(dǎo)體間的電弧火災(zāi)”。這是因為“在電氣線路施工中，穿鋼管拉電線時帶電導(dǎo)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(dǎo)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，它對電氣線路將感應(yīng)瞬態(tài)過電壓”，此時“芯線上感應(yīng)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。 </p> <p> 爬電起火：爬電是指電弧不是建立在空氣間隙中的電弧，而是出現(xiàn)在設(shè)備絕緣表面上的電弧。例如電源插頭的絕緣表面上的一個或多個相線插腳和PE線插腳，它們之間的絕緣表面可能發(fā)生爬電。武漢弧光保護(hù)維修</p><p
