目前南京、保定的生產(chǎn)廠家都是采用一體式的裝置，只有早起仿ABB、VAMP、UTU的廠家按照進(jìn)口產(chǎn)品的結(jié)構(gòu)模式做的，各個單元之間通過電纜連接，人為增加了節(jié)點(diǎn)，反而降低了設(shè)備的可靠性。zhidao </p> <p> 弧光保護(hù)的技術(shù)發(fā)源地在芬蘭。ABB的REA系列，Vamp的321,221系列，在國內(nèi)都有比較多的應(yīng)用，還有Arcteq、UTU 也都有較成熟的弧光保護(hù)產(chǎn)品。 </p> <p>

電弧光保護(hù)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(hù)附近工作人員及設(shè)備。電弧保護(hù)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(hù)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(shí)現(xiàn)。 </p> <p> 電弧光保護(hù)系統(tǒng)通過檢測開關(guān)柜內(nèi)部發(fā)生故障時發(fā)出的電弧光判斷是否發(fā)生故障。弧光是電弧**明顯且變化**快的特征物理量，因而電弧光保護(hù)具有超高速的動作性能，整套保護(hù)的動作時間可保證在幾毫秒以內(nèi)。對于開關(guān)柜內(nèi)部故障保護(hù)來講，這種超調(diào)整動作性能是**重要的。為了避免外界光干擾可能引發(fā)系統(tǒng)的誤跳閘，在實(shí)際應(yīng)用中往往還引入過流閉鎖信號，即：只有同時檢測到弧光信號及過流動作信號才發(fā)出跳閘指令切除故障，從而進(jìn)一步提高保護(hù)系統(tǒng)動作的可靠性。智能弧光保護(hù)弧光保護(hù)**，歡迎來電咨詢。</p><div

<br /> </p> <p> 電弧光在中、低壓開關(guān)柜內(nèi)產(chǎn)生的主要因素是什么？ </p> <p> <br /> </p> <p> 使用了不良性能的導(dǎo)電體 </p> <p> <br /> </p> <p> 絕緣材料的損壞（包括：裂痕，進(jìn)水，老化等） </p> <p> <br /> </p> <p> 人體或其他物品意外地接觸到帶電的物品 </p> <p> <br /> </p> <p> 操作過程中的失誤或者設(shè)計(jì)或安裝錯誤 </p> <p> <br /> </p> <p> 元件損壞，沒有良好的維修和保養(yǎng)設(shè)備 </p> <p> <br /> </p> <p> 過電壓 </p> <p> <br /> </p> <p> 電網(wǎng)結(jié)構(gòu)的改變（系統(tǒng)容量增大、電纜應(yīng)用增多） </p><p> 帶電導(dǎo)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(dǎo)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(diǎn)金屬熔化，之后金屬熔化成團(tuán)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(yán)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(yuǎn)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(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?yàn)椤半姎饩€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(yùn)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，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。專業(yè)生產(chǎn)電弧光保護(hù)裝置廠家。</p><div

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(yùn)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(qiáng)，跳閘信號可以非常迅速的輸出到斷路器。超穩(wěn)定弧光保護(hù)，廠家直銷。河南弧光保護(hù)OEM</p><p

中、低壓母線在發(fā)生短路故障、運(yùn)行人員誤操作和誤入帶電間隔等原因產(chǎn)生的電弧光對設(shè)備及人員造成的危害極大。電弧光使開關(guān)設(shè)備內(nèi)的壓力和溫度迅速升高，如不及時切除，容易造成電纜護(hù)套著火和母線熔毀，并且產(chǎn)生大量有害氣體傷害呼吸系統(tǒng)、高溫灼傷皮膚和刺傷眼睛。短路故障時，開關(guān)設(shè)備劇烈震動使固定件松動脫落、甚至導(dǎo)致開關(guān)柜造成人員傷亡。中低壓母線系統(tǒng)中一般不配置**的快速母線保護(hù)，而是依賴上一級的后備過流保護(hù)切除母線故障，過流保護(hù)有延時，這就導(dǎo)致故障切除時間較長，增加了設(shè)備的損害程度。電弧光保護(hù)系統(tǒng)原理簡單、動作迅速可靠，能夠有效減輕電弧光對設(shè)備和人身的傷害。云南弧光保護(hù)測控</p><p
