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、故障信息讀取、復(fù)歸等操作，方便組網(wǎng)運行。 </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。弧光采集單元通常安裝在選定的開關(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。穩(wěn)定性好，保護功能強大，母線弧光保護，廠家直銷。</p><div style="width:100%;text-align:
