1）弧光保護主控單元：主單元為電弧光保護系統(tǒng)的控制中心，收集動作信號并對收集的數(shù)據(jù)進行處理、判斷、發(fā)出跳閘信號以切除故障。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，可通過后臺對設(shè)備進行參數(shù)設(shè)置、實時數(shù)據(jù)讀取，數(shù)字化弧光保護哪家好、故障信息讀取、復(fù)歸等操作，方便組網(wǎng)運行，數(shù)字化弧光保護哪家好。 </p> <p> 2）采集單元：弧光采集單元與主控單元配合使用，數(shù)字化弧光保護哪家好，是弧光保護系統(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)果通過光信號傳遞給主控單元。單個弧光采集單元可以安裝,16個弧光探頭，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?；」獠杉瘑卧ǔ０惭b在選定的開關(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，是無源的弧光探測傳感器，安裝在開關(guān)柜的母線室內(nèi)或饋線柜內(nèi)電氣元件的連接處。當發(fā)生弧光故障時，光照度大幅度增加，弧光傳感器直接將光信號傳給弧光采集單元或饋線保護單元。 </p><div style="width:100%;text-align: center;"><img

目**80伏/1千伏/3千伏/6千伏/10千伏/35千伏開關(guān)柜中沒有**的母線主保護,但在國外電力行業(yè)已經(jīng)普及95%以上;國內(nèi)采用變壓器過流保護用于母線后備保護,理論上必須延時300~500毫秒,實際上動作時間可能長達1.5~2秒,起不到對母線的真正保護,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是有缺點的 </p> <p> 從弧光保護設(shè)計的系統(tǒng)可靠性來看,變壓器、進線、饋線都有主保護,唯獨母線沒有**的主保護,我們認為母線應(yīng)該增加**主保護。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)計方面建議配置母線**主保護弧光保護,以確保操作人員的人身安全及系統(tǒng)的安全、穩(wěn)定運行。
