在柜體內(nèi)形成電弧的過程可分為四個階段: </p> <p> 壓縮階段:電弧占據(jù)了整個空氣空間，由于持續(xù)的釋放能量產(chǎn)生過熱，導致對流和輻射，保留在柜內(nèi)的空氣被加熱，在整個初級階段不同區(qū)域的溫度和壓力值不一樣。 </p> <p> 擴展階段:從這一瞬間開始，內(nèi)部壓力增加，由于過熱的空氣開始流動而形成一個空洞。在這個階段其壓力達到比較大值，并因為熱空氣的釋放而開始減弱。 </p> <p> 發(fā)射階段:由于電弧能量的持續(xù)釋放，幾乎所有的空氣均被一個緩和但恒定的壓力擠壓出去。 </p> <p> 發(fā)熱階段:在驅(qū)逐出空氣后，煙臺高壓弧光保護，柜內(nèi)的溫度幾乎達到電弧的溫度。***階段就由此開始，直至熄滅。此時，所有金屬和絕緣體在受到產(chǎn)生的氣體、霧和溶蝕物質(zhì)顆粒的侵蝕后，煙臺高壓弧光保護，已融為一體了。 </p> <p> 當電弧出現(xiàn)在非常封閉的設(shè)備環(huán)境時，可能不會出現(xiàn)上述某些階段或者只有較少的影響;然而，在電弧的周圍，會形成壓力波、并導致溫度的上升。電弧光保護裝置，煙臺高壓弧光保護，質(zhì)量可靠，性能穩(wěn)定。煙臺高壓弧光保護</p><div style="width:100%;text-align: center;"><img

帶電導體間的電弧性短路起火：短路起火時有兩種可能，其一是兩導體（如相線與中性線）接觸時因短路電流產(chǎn)生的高溫，使接觸點金屬熔化，之后金屬熔化成團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遠大于上述金屬性短路的起火危險。 </p> <p> <br /> </p> <p> 接地故障電弧起火：由于接地故障發(fā)生的幾率遠大于帶電導體間的短路”所以“接地故障電弧引起的火災(zāi)遠多于帶電導體間的電弧火災(zāi)”這是因為“電氣線路施工中，穿鋼管拉電線時帶電導體絕緣外皮之間并無因相對運動而產(chǎn)生的摩擦，但帶電導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，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。煙臺高壓弧光保護高精度弧光保護，專業(yè)生產(chǎn)廠家，歡迎來電咨詢。</p><div

主動保護有以下兩種常見的可行的方法：1通過壓力傳感器進行監(jiān)測;2通過弧光傳感器進行監(jiān)測 </p> <p> <br /> </p> <p> 第一種方法（采用壓力傳感器作為電弧光探測單元）壓力波是裝置內(nèi)出現(xiàn)電弧故障的效應(yīng)之一，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壓力峰值。當內(nèi)部的壓力達到設(shè)定值時，電弧監(jiān)測裝置發(fā)出動作指令，控制開關(guān)器件動作。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> <br /> </p> <p> 第二種方法（采用光纖傳感器作為電弧光探測單元）弧光監(jiān)測器的操作邏輯如下：電弧現(xiàn)象會產(chǎn)生強烈的光輻射，因此柜體內(nèi)出現(xiàn)的弧光可以被弧光傳感器探測到當弧光監(jiān)控系統(tǒng)探測到故障，會發(fā)出動作信號給斷路器。這種方法的探測反應(yīng)時間*為1毫秒?；」鈧鞲衅鞣譃榭煞譃殡娏餍秃凸饫w性（可見光和紫外光）其中支持可見光的弧光傳感器有基頓電氣JD9900B系列弧光傳感器。專業(yè)生產(chǎn)電弧光保護裝置，歡迎來電咨詢。保定弧光保護裝置型號</p><p

的電壓。也就是說只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導體間的電弧、帶電導體與地之間的電弧和絕緣表面的爬電。 </p> <p> 帶電導體間的電弧性短路起火：短路起火時有兩種可能，其一是兩導體（如相線與中性線）接觸時因短路電流產(chǎn)生的高溫，使接觸點金屬熔化，之后金屬熔化成團收縮而脫離接觸的過程，在這種情況下可能建立電弧?！坝秩缇€路絕緣水平嚴重下降，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?！薄半娀⌒远搪返钠鸹鹞ｋU遠大于上述金屬性短路的起火危險?！?煙臺高壓弧光保護</p><p
