(1)主控單元用于管理、控制整套電弧光保護(hù)系統(tǒng)。它檢測故障電流和弧光信號，并對收到的兩種信號進(jìn)行處理、判斷，在滿足跳閘的條件時，發(fā)出跳閘指令切除故障。 </p> <p> 主控單元有4個數(shù)據(jù)輸入接口，共可接入24個弧光單元或電流單元；輸出接口包括4路快速跳閘輸出和6路常規(guī)繼電器跳閘輸出共有4+16個弧光檢測口。當(dāng)弧光信號輸入超過16個時。推薦采用弧光單元。主控單元根據(jù)弧光單元或者弧光傳感器輸送的信號，能準(zhǔn)確地判斷故障點(diǎn)位置。 </p> <p> (2)電流單元用于檢測過電流信號，ABC三相電流均可檢測，電流單元檢測到的信號通過光纖和數(shù)據(jù)線傳到主控單元，主控單元依據(jù)設(shè)定的邏輯判斷是否發(fā)出跳閘指令。 </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)椤霸陔姎饩€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，它對電氣線路將感應(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。 </p> <p> 爬電起火：爬電是指電弧不是建立在空氣間隙中的電弧，而是出現(xiàn)在設(shè)備絕緣表面上的電弧。例如電源插頭的絕緣表面上的一個或多個相線插腳和PE線插腳，它們之間的絕緣表面可能發(fā)生爬電。超穩(wěn)定弧光保護(hù)，廠家直銷。</p><div style="width:100%;text-align: center;"><img
