style="text-indent:25px">電弧光保護(hù)裝置分為饋線電弧光保護(hù)和母線電弧光保護(hù)、主要用于保護(hù)重點(diǎn)設(shè)備和相關(guān)工作人員的生命安全。在以前，由于技術(shù)還不是特別成熟、考慮也不是特別周全、我國(guó)的大部分中，鄭州弧光保護(hù)如何選型、低壓母線沒有裝設(shè)快速的母線保護(hù)，只是采用了簡(jiǎn)單的消弧裝置和變壓器后備保護(hù)。這些保護(hù)存在動(dòng)作速度慢、故障切除時(shí)間長(zhǎng)等缺點(diǎn)，嚴(yán)重的影響了整個(gè)電網(wǎng)的安全運(yùn)行。而電弧光保護(hù)裝置就是專門為解決這些問題而誕生的繼電保護(hù)設(shè)備。我公司生產(chǎn)的電弧光保護(hù)裝置適用于110KV、66KV、35KV

開關(guān)柜內(nèi)的發(fā)生短路弧光的功率可高達(dá)100MW，電弧燃燒所產(chǎn)生的能量與電弧的燃燒時(shí)間及短路電流變化值呈幾何倍增長(zhǎng)，燃燒產(chǎn)生的高溫、高壓將會(huì)逐步摧毀元器件、銅排以及成列的開關(guān)柜，高明亮的弧光和有害氣體對(duì)人體也有巨大的傷害。如左圖的電弧光危害示意圖所示，保護(hù)裝置動(dòng)作時(shí)間不能超過20ms，否則會(huì)產(chǎn)生不可修復(fù)的器件損壞，從而延長(zhǎng)故障修復(fù)時(shí)間。電弧光的燃弧時(shí)間長(zhǎng)短和對(duì)設(shè)備造成的損壞程度的評(píng)估如下所示

引起開關(guān)柜弧光短路故障的原因很多，主要有：絕緣故障、載流回路不良、外來物體的進(jìn)入、人為操作錯(cuò)誤、系統(tǒng)改變或故障等。 </p> <p> 1.2 電弧光的能量 </p> <p> 開關(guān)柜發(fā)生內(nèi)部弧光故障產(chǎn)生的短路功率可高達(dá)8~60 MW，所產(chǎn)生的能量與電弧的燃燒時(shí)間、短路電流的平方值、柜體幾何尺寸以及所使用的材料等因素有關(guān)，其中**主要的因素是短路故障電流及電弧燃燒的時(shí)間，電弧能量與有關(guān)電弧燃燒的時(shí)間的關(guān)系如圖所示。從圖中可以看出，電弧燃燒持續(xù)時(shí)間超過100 ms ，所釋放的能量開始急劇增加，接著各種故障效應(yīng)對(duì)開關(guān)設(shè)備的電纜、銅排以及鋼材造成嚴(yán)重?fù)p壞. </p> <p> <br /> </p><p> 電弧光保護(hù)與母線保護(hù) </p> <p> 電弧光保護(hù)是動(dòng)作時(shí)間**短的母線保護(hù)。 </p> <p> 而為什么其他母線保護(hù)的動(dòng)作時(shí)間那么長(zhǎng)，因?yàn)椤氨Ｗo(hù)配合”。電弧光保護(hù)只要滿足“電弧”和“過流”等判據(jù)就可立即發(fā)出跳閘指令。而其他母線保護(hù)（參考西門子公司7SD和7SJ62綜保裝置）當(dāng)滿足“過流”判據(jù)后還必須等待下級(jí)負(fù)載的“無過流匯報(bào)”后才可以發(fā)出跳閘指令。因?yàn)橄录?jí)負(fù)載短路和母線短路都會(huì)造成進(jìn)線開關(guān)“過流”，如果下級(jí)負(fù)載短路應(yīng)該讓下級(jí)負(fù)載開關(guān)來切除，母線短路則由母線進(jìn)線開關(guān)來切除。電弧光保護(hù)猶如手持尚方寶劍，而其他母線保護(hù)則就像一個(gè)團(tuán)隊(duì)，不敢輕舉妄動(dòng)。 </p> <p> 總上所述，采用電弧光母線保護(hù)可以在現(xiàn)有開關(guān)柜的電弧耐受時(shí)間標(biāo)準(zhǔn)以內(nèi)切除弧光短路故障，從而比較大限度地保護(hù)了附近工作人員，使開關(guān)裝置等配電設(shè)備免受損壞，很大減少了設(shè)備維修費(fèi)用及維修故障所需的停電時(shí)間，因而具有明顯的經(jīng)濟(jì)效益，為理想的中壓母線保護(hù)解決方案。電弧光保護(hù)裝置廠家直銷，歡迎來電咨詢。</p><div

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。 </p> <p> 4、強(qiáng)大的電氣性能 </p> <p> 弧光探頭設(shè)計(jì)、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。裝置完全弧光保護(hù)生產(chǎn)廠家，歡迎來電咨詢。成都高精度弧光保護(hù)</p><p style="text-indent:25px">電弧光保護(hù)廠家直銷，可提供OEM，歡迎來電咨詢。鄭州弧光保護(hù)如何選型</p><p>

加上斷路器動(dòng)作時(shí)間，差動(dòng)保護(hù)和無時(shí)限電流速斷保護(hù)動(dòng)作，故障切除時(shí)間約100ms。即使電流速斷保護(hù)比弧光保護(hù)多40ms,查看弧光危害示意圖，電纜已經(jīng)燃燒。如果是帶時(shí)限電流速斷保護(hù)延時(shí)100ms、過電流Ⅰ段延時(shí)300ms,已經(jīng)達(dá)到柜體燃燒甚至的可能。鄭州弧光保護(hù)如何選型</p><p
