在110KV變電站的中低壓母線一般不配置母線保護(hù)，近年來為了有效控制變電站中低壓母線開關(guān)設(shè)備損壞及母線和斷路器故障引起主變壓器損壞的發(fā)生，越來越多的變電站中低壓開關(guān)柜配置電弧光保護(hù)。通過弧光保護(hù)裝置可以快速地切除故障點(diǎn)，保證系統(tǒng)的安全穩(wěn)定運(yùn)行。 </p> <p> 應(yīng)用范圍 </p> <p> 適用于電力開關(guān)柜中，引入電弧光保護(hù)裝置，可以捕捉到電氣弧光，并快速地切除故障點(diǎn)，保證電力系統(tǒng)的安全穩(wěn)定運(yùn)行。 </p> <p> 主要特點(diǎn) </p> <p> 1、動(dòng)作迅速可靠 </p> <p> 采用了可靠的快速算法，可以在短時(shí)間內(nèi)判斷弧光變化信號(hào)和電流變化信號(hào)并迅速出口，從發(fā)現(xiàn)故障到出口跳閘時(shí)間間隔優(yōu)于10ms，確保開關(guān)柜內(nèi)設(shè)備的弧光在75ms以內(nèi)切除。 </p> <p> 2、全數(shù)字化設(shè)計(jì) </p> <p> 本裝置采用全數(shù)字化設(shè)計(jì)，配置靈活，動(dòng)作精度高，而且排除了由于旋鈕或其他機(jī)械設(shè)計(jì)導(dǎo)致的誤差***。 </p> <p> 3、保護(hù)原理簡(jiǎn)單、合理 </p> <p> 根據(jù)弧光產(chǎn)生時(shí)的特點(diǎn)，裝置采用弧光和電流雙重判據(jù)，判據(jù)簡(jiǎn)單且可以有效的保證動(dòng)作的準(zhǔn)確性，濮陽(yáng)弧光保護(hù)作用。 </p> <p> 4、強(qiáng)大的電氣性能 </p> <p> 弧光探頭設(shè)計(jì)，濮陽(yáng)弧光保護(hù)作用，濮陽(yáng)弧光保護(hù)作用、連接線等全部采用耐高溫、阻燃的高分子材料，具有強(qiáng)大的電氣隔離效果。裝置完全高壓弧光保護(hù)**，廠家直銷，歡迎來電咨詢。濮陽(yáng)弧光保護(hù)作用</p><div style="width:100%;text-align: center;"><img

集中和分散式各有優(yōu)劣，早期國(guó)外是分散式的，國(guó)內(nèi)的集中式更多一些，從可靠性角度，集中式只有一個(gè)有源設(shè)備，光專纖和探頭都是無源，因此更可靠，對(duì)于柜子較多時(shí)，可采用兩臺(tái)集中或一臺(tái)加擴(kuò)屬展模塊的形式接入更多的探測(cè)點(diǎn)，國(guó)內(nèi)的南瑞基頓電氣等弧光保護(hù)都支持這種模式。秦皇島弧光保護(hù)維修智能電弧光保護(hù)裝置**，廠家直銷，歡迎咨詢。</p><div

</p> <p> 在柜體內(nèi)形成電弧的過程可分為四個(gè)階段: </p> <p> 壓縮階段:電弧占據(jù)了整個(gè)空氣空間，由于持續(xù)的釋放能量產(chǎn)生過熱，導(dǎo)致對(duì)流和輻射，保留在柜內(nèi)的空氣被加熱，在整個(gè)初級(jí)階段不同區(qū)域的溫度和壓力值不一樣。 </p> <p> 擴(kuò)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(dòng)而形成一個(gè)空洞。在這個(gè)階段其壓力達(dá)到比較大值，并因?yàn)闊峥諝獾尼尫哦_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(gè)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，柜內(nèi)的溫度幾乎達(dá)到電弧的溫度。***階段就由此開始，直至熄滅。此時(shí)，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，已融為一體了。 </p> <p> 當(dāng)電弧出現(xiàn)在非常封閉的設(shè)備環(huán)境時(shí)，可能不會(huì)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(huì)形成壓力波、并導(dǎo)致溫度的上升。 </p><p> 弧裝置為當(dāng)系統(tǒng)饋線發(fā)生單相接地故障時(shí)（非長(zhǎng)久性故障，可持續(xù)運(yùn)行2小時(shí)），系統(tǒng)電容放電，消弧柜中的消弧線圈進(jìn)行補(bǔ)償限制系統(tǒng)電壓的升高，減少或消除接地時(shí)產(chǎn)生的電弧。 </p> <p> 母線弧光保護(hù)系統(tǒng)為當(dāng)母線發(fā)生相對(duì)相或相對(duì)地弧光故障時(shí)（長(zhǎng)久性故障），采集柜內(nèi)弧光信號(hào)，同時(shí)采集進(jìn)線的過流信號(hào)，快速的選擇性切除故障。 </p> <p> 綜上，兩個(gè)設(shè)備保護(hù)的對(duì)象和作用完全不同。消弧柜針對(duì)饋線，弧光保護(hù)針對(duì)母線。消弧裝置為了保證供電設(shè)備正常運(yùn)行，而母線弧光保護(hù)系統(tǒng)是在供電系統(tǒng)發(fā)生弧光故障時(shí)，可以在100ms內(nèi)切除故障，比較大限度的保護(hù)人身安全并減少財(cái)產(chǎn)損失。弧光保護(hù)生產(chǎn)廠家，歡迎來電咨詢。</p><div

電弧光保護(hù)目的是在發(fā)生電弧故障時(shí)，通過限制電弧燃燒時(shí)間來保護(hù)附近工作人員及設(shè)備。電弧保護(hù)首先必須檢測(cè)故障電弧，然后才能切斷流過的故障電流。在中低開關(guān)柜內(nèi)部故障保護(hù)中，一般是通過跳開斷路器來切除故障使故障電弧熄滅。電弧燃燒時(shí)伴隨著光、聲及電磁波形式的輻射。通過分析可見光、聲波、紅外線或無線電頻率的輻射可以檢測(cè)到電弧的存在，甚至連由電弧產(chǎn)生的壓力波也已經(jīng)用來檢測(cè)它的存在。然而，*****使用的方法還是通過檢測(cè)可見光來實(shí)現(xiàn)。
