src="https://tyunfile.71360.com/UploadFile/keaton/637255090208583984/7334798.jpg"></div><p> 電弧光保護(hù)系統(tǒng)由以下主要部件組成： </p> <p> 1）弧光保護(hù)主控單元：主單元為電弧光保護(hù)系統(tǒng)的控制中心，收集動(dòng)作信號(hào)并對(duì)收集的數(shù)據(jù)進(jìn)行處理、判斷、發(fā)出跳閘信號(hào)以切除故障。設(shè)備自帶四路輸出接口分別為弧光跳閘出口1、弧光跳閘出口2、弧光跳閘出口3、跳閘總出口4。設(shè)備支持ModBUS-RTU規(guī)約，可通過(guò)后臺(tái)對(duì)設(shè)備進(jìn)行參數(shù)設(shè)置、實(shí)時(shí)數(shù)據(jù)讀取、故障信息讀取、復(fù)歸等操作，方便組網(wǎng)運(yùn)行。 </p> <p> 2）采集單元：弧光采集單元與主控單元配合使用，是弧光保護(hù)系統(tǒng)的重要組成部分，主要用于采集故障弧光，并將判斷后的結(jié)果通過(guò)光信號(hào)傳遞給主控單元。單個(gè)弧光采集單元可以安裝,16個(gè)弧光探頭，根據(jù)系統(tǒng)的大小可以任意增減弧光采集單元的數(shù)量。弧光采集單元通常安裝在選定的開(kāi)關(guān)柜內(nèi)中，選擇的原則是保證該單元相關(guān)光纖用量盡量少。 </p> <p> 3）弧光傳感器：專門用于故障弧光采集，是無(wú)源的弧光探測(cè)傳感器，安裝在開(kāi)關(guān)柜的母線室內(nèi)或饋線柜內(nèi)電氣元件的連接處。當(dāng)發(fā)生弧光故障時(shí)，光照度大幅度增加，弧光傳感器直接將光信號(hào)傳給弧光采集單元或饋線保護(hù)單元。 </p><p> 目**80伏/1千伏/3千伏/6千伏/10千伏/35千伏開(kāi)關(guān)柜中沒(méi)有**的母線主保護(hù),但在國(guó)外電力行業(yè)已經(jīng)普及95%以上;國(guó)內(nèi)采用變壓器過(guò)流保護(hù)用于母線后備保護(hù),理論上必須延時(shí)300~500毫秒,實(shí)際上動(dòng)作時(shí)間可能長(zhǎng)達(dá)1.5~2秒,起不到對(duì)母線的真正保護(hù),并且使變壓器低壓側(cè)絕緣有較大的結(jié)構(gòu)性損壞,所以目前的母線后備保護(hù)是有缺點(diǎn)的 </p> <p> 從弧光保護(hù)設(shè)計(jì)的系統(tǒng)可靠性來(lái)看,變壓器、進(jìn)線、饋線都有主保護(hù),唯獨(dú)母線沒(méi)有**的主保護(hù),我們認(rèn)為母線應(yīng)該增加**主保護(hù)。雖然母線故障出現(xiàn)概率較低,但一旦出現(xiàn)將損失慘重。因此,從技術(shù)、設(shè)計(jì)方面建議配置母線**主保護(hù)弧光保護(hù),以確保操作人員的人身安全及系統(tǒng)的安全、穩(wěn)定運(yùn)行。電弧光保護(hù)裝置，質(zhì)量可靠，性能穩(wěn)定。</p><div
