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?；」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(cè)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(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。開封數(shù)字化弧光保護(hù)性價(jià)比高，弧光保護(hù)全國招商。</p><div

</p> <p> 設(shè)備安裝限流斷路器 </p> <p> 主動(dòng)保護(hù)有以下兩種常見的、可行的方法：1）通過壓力傳感器進(jìn)行監(jiān)測(cè);2）通過弧光傳感器進(jìn)行監(jiān)測(cè) </p> <p> ***種方法（采用壓力傳感器作為電弧光探測(cè)單元）壓力波是裝置內(nèi)出現(xiàn)電弧***的效應(yīng)之一，它將在電弧出現(xiàn)后的10-15毫秒后出現(xiàn)，可以安裝一些壓力傳感器用于探測(cè)壓力峰值。當(dāng)內(nèi)部的壓力達(dá)到設(shè)定值時(shí)，電弧監(jiān)測(cè)裝置發(fā)出動(dòng)作指令，控制開關(guān)器件動(dòng)作。但是要預(yù)先確定電弧在柜內(nèi)產(chǎn)生的過壓值并非易事。 </p> <p> 第二種方法（采用光纖傳感器作為電弧光探測(cè)單元）弧光監(jiān)測(cè)器的操作邏輯如下：電弧現(xiàn)象會(huì)產(chǎn)生強(qiáng)烈的光輻射，因此柜體內(nèi)出現(xiàn)的弧光可以被弧光傳感器探測(cè)到。當(dāng)弧光監(jiān)控系統(tǒng)探測(cè)到故障，會(huì)發(fā)出動(dòng)作信號(hào)給斷路器。這種方法的探測(cè)反應(yīng)時(shí)間*為1毫秒。 </p><p> 帶電導(dǎo)體間的電弧性短路起火：短路起火時(shí)有兩種可能，其一是兩導(dǎo)體（如相線與中性線）接觸時(shí)因短路電流產(chǎn)生的高溫，使接觸點(diǎn)金屬熔化，之后金屬熔化成團(tuán)收縮而脫離接觸的過程，這種情況下可能建立電弧。又如線路絕緣水平嚴(yán)重下降，雷電產(chǎn)生的瞬態(tài)過電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過電壓都可能擊穿劣化的線路絕緣而建立電弧。電弧性短路的起火危險(xiǎn)遠(yuǎn)大于上述金屬性短路的起火危險(xiǎn)。

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)椤半姎饩€路施工中，穿鋼管拉電線時(shí)帶電導(dǎo)體絕緣外皮之間并無因相對(duì)運(yùn)動(dòng)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(shí)地面上出現(xiàn)瞬變電磁場(chǎng)，對(duì)電氣線路將感應(yīng)瞬態(tài)過電壓”此時(shí)“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(duì)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。專業(yè)生產(chǎn)弧光保護(hù)，歡迎來電咨詢。</p><div
