</p> <p> <br /> </p> <p> 本帖***由 bzp4891 于 2016-5-19 12:02 編輯 </p> <p> 1、首先動(dòng)作時(shí)間是否能保證在***擴(kuò)大前切除電源？這個(gè)不清楚 </p> <p> -----這個(gè)有時(shí)間可以保證，而且這個(gè)時(shí)間確實(shí)很短，一般廠家通過實(shí)際驗(yàn)證后給出斷路器與弧光保護(hù)裝置在故障情況下動(dòng)作的時(shí)間； </p> <p> 2、圖中是固定分割或抽屜柜，安裝在動(dòng)力電纜室內(nèi)？這里發(fā)生短路的幾率很小，除非連接不可靠，端子布置不合理，按照這種檢測(cè)，抽屜或分隔內(nèi)和饋出線側(cè)發(fā)生的弧光短路***也無法及時(shí)切斷電源。這種檢測(cè)方式適用于固定柜，武漢數(shù)字化弧光保護(hù)。 </p> <p> ----弧光傳感器**合適的位置我認(rèn)為在主母線室內(nèi)，用于主母線發(fā)生短路故障情況下切斷主開關(guān)以防止***擴(kuò)大化，如果非要安裝在饋線柜例如抽屜柜或固定分隔柜的電纜室，一是安裝的傳感器的數(shù)量很多成本難以承受，二是如果抽屜回路的某一個(gè)回路發(fā)生，傳感器的檢測(cè)會(huì)不會(huì)誤動(dòng)作，跳閘沒有發(fā)生故障的回路； </p> <p> <br /> 電弧光保護(hù)裝置，武漢數(shù)字化弧光保護(hù)，質(zhì)量可靠，性能穩(wěn)定。武漢數(shù)字化弧光保護(hù)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

電弧光保護(hù)目的是在發(fā)生電弧故障時(shí)，通過限制電弧燃燒時(shí)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(cè)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(shí)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(cè)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(cè)它的存在。然而，*****使用的方法還是通過檢測(cè)可見光來實(shí)現(xiàn)。 </p> <p> 電弧光保護(hù)系統(tǒng)通過檢測(cè)開關(guān)柜內(nèi)部發(fā)生故障時(shí)發(fā)出的電弧光判斷是否發(fā)生故障?；」馐请娀?*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(dòng)作性能，整套保護(hù)的動(dòng)作時(shí)間可保證在幾毫秒以內(nèi)。對(duì)于開關(guān)柜內(nèi)部故障保護(hù)來講，這種超調(diào)整動(dòng)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(hào)，即：只有同時(shí)檢測(cè)到弧光信號(hào)及過流動(dòng)作信號(hào)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(dòng)作的可靠性。天津高壓弧光保護(hù)電弧光保護(hù)裝置廠家直銷，歡迎來咨詢。</p><div

style="text-indent:25px">電弧光保護(hù)裝置分為饋線電弧光保護(hù)和母線電弧光保護(hù)、主要用于保護(hù)重點(diǎn)設(shè)備和相關(guān)工作人員的生命安全。在以前，由于技術(shù)還不是特別成熟、考慮也不是特別周全、我國(guó)的大部分中、低壓母線沒有裝設(shè)快速的母線保護(hù)，只是采用了簡(jiǎn)單的消弧裝置和變壓器后備保護(hù)。這些保護(hù)存在動(dòng)作速度慢、故障切除時(shí)間長(zhǎng)等缺點(diǎn)，嚴(yán)重的影響了整個(gè)電網(wǎng)的安全運(yùn)行。而電弧光保護(hù)裝置就是專門為解決這些問題而誕生的繼電保護(hù)設(shè)備。我公司生產(chǎn)的電弧光保護(hù)裝置適用于110KV、66KV、35KV 、10KV及0.4KV的電壓等級(jí)，既可以分散在開關(guān)柜就地安裝，也可以集中組屏安裝，提供以太網(wǎng)、RS485通訊接口，可以和其它保護(hù)、自動(dòng)化設(shè)備一起，通過通信接口組成自動(dòng)化系統(tǒng)。</p><p style="text-indent:25px">電弧光保護(hù)系統(tǒng)可以在開關(guān)柜發(fā)生弧光故障的時(shí)候，保護(hù)操作人員不受傷害，并且降低財(cái)產(chǎn)損失程度。當(dāng)出現(xiàn)弧光時(shí)候，弧光以 300m/s 的速度爆發(fā)，摧毀途中的任何物質(zhì).。只要系統(tǒng)中不斷電，弧光就會(huì)一直存在。要想比較大限度的減少弧光的危害，我們需要一種安全、迅速而有效的半導(dǎo)體電弧光保護(hù)系統(tǒng)。在開關(guān)柜抽屜內(nèi)，弧光可以迅速的在 10ms內(nèi)達(dá)到 3m遠(yuǎn)，因此要想很大程度降低損失，時(shí)間是個(gè)**主要的因素。KEATON電弧光保護(hù)系統(tǒng)輸出跳閘信號(hào)時(shí)間極短，即使在安裝或者維護(hù)的時(shí)候也能保護(hù)操作人員的安全。各種弧光保護(hù)廠家直銷。</p><div style="width:100%;text-align: center;"><img
