設(shè)備安裝限制內(nèi)部電弧效應(yīng)的裝置（主動(dòng)保護(hù)） </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(jiàn)的、可行的方法：1）通過(guò)壓力傳感器進(jìn)行監(jiān)測(cè);2）通過(guò)弧光傳感器進(jìn)行監(jiān)測(cè) </p> <p> 第一種方法（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(kāi)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(guò)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(xiàn)與中性線(xiàn)）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(guò)程，這種情況下可能建立電弧。又如線(xiàn)路絕緣水平嚴(yán)重下降，雷電產(chǎn)生的瞬態(tài)過(guò)電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過(guò)電壓都可能擊穿劣化的線(xiàn)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)。 </p> <p> <br /> </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)椤半姎饩€(xiàn)路施工中，穿鋼管拉電線(xiàn)時(shí)帶電導(dǎo)體絕緣外皮之間并無(wú)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(xiàn)路將感應(yīng)瞬態(tài)過(guò)電壓”此時(shí)“芯線(xiàn)上感應(yīng)的瞬態(tài)過(guò)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(xiàn)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。弧光保護(hù)專(zhuān)業(yè)生產(chǎn)廠(chǎng)家，歡迎來(lái)電咨詢(xún)。</p><div

-----這個(gè)有時(shí)間可以保證，而且這個(gè)時(shí)間確實(shí)很短，一般廠(chǎng)家通過(guò)實(shí)際驗(yàn)證后給出斷路器與弧光保護(hù)裝置在故障情況下動(dòng)作的時(shí)間； </p> <p> 2、圖中是固定分割或抽屜柜，安裝在動(dòng)力電纜室內(nèi)？這里發(fā)生短路的幾率很小，除非連接不可靠，端子布置不合理，按照這種檢測(cè)，抽屜或分隔內(nèi)和饋出線(xiàn)側(cè)發(fā)生的弧光短路***也無(wú)法及時(shí)切斷電源。這種檢測(cè)方式適用于固定柜。 </p> <p>
