</p> <p> 應(yīng)用范圍 </p> <p> 適用于電力開(kāi)關(guān)柜中，引入電弧光保護(hù)裝置，可以捕捉到電氣弧光，智能弧光保護(hù)測(cè)控，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，智能弧光保護(hù)測(cè)控，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(kāi)關(guān)柜內(nèi)設(shè)備的弧光在75ms以內(nèi)切除，智能弧光保護(hù)測(cè)控。 </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。裝置完全光電式電弧光保護(hù)，廠家直銷，歡迎咨詢。智能弧光保護(hù)測(cè)控</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

電力系統(tǒng)中,每年都會(huì)有多名電力工程師或電工被電弧擊傷,在電力安全備受重視的***,如何更好地保證人身安全,保證供電系統(tǒng)的穩(wěn)定可靠運(yùn)行是至關(guān)重要的。據(jù)記者了解,我國(guó)電力系統(tǒng)中,35kV及以下電壓等級(jí)的母線一般未裝設(shè)弧光保護(hù)。近年來(lái),由于各種原因開(kāi)關(guān)設(shè)備被嚴(yán)重?zé)龤?據(jù)統(tǒng)計(jì)資料表明,每年每1000臺(tái)開(kāi)關(guān)柜就有7臺(tái)遭到損壞,故障率0.7%。農(nóng)村配電網(wǎng)的概率更高,達(dá)1.2%。,有的甚至發(fā)展成“火燒連營(yíng)”的***,這些配網(wǎng)***處理不當(dāng)甚至被擴(kuò)大發(fā)展為輸電網(wǎng)***,造成重大的經(jīng)濟(jì)損失,已引起電力部門(mén)的***關(guān)注。 </p> <p> 中、低壓母線發(fā)生短路故障時(shí),所產(chǎn)生的電弧光對(duì)設(shè)備及人員會(huì)造成極大的傷害。總結(jié)其***原因大多是因?yàn)闆](méi)有裝設(shè)中低壓母線保護(hù),未能快速切除故障造成的,單獨(dú)地依賴上一級(jí)變壓器的后備保護(hù)切除母線短路故障,這樣導(dǎo)致了故障切除時(shí)間的延長(zhǎng),加大了設(shè)備的損傷程度,破壞嚴(yán)重時(shí)可能造成***進(jìn)一步擴(kuò)大,威脅到系統(tǒng)的穩(wěn)定運(yùn)行。昆明弧光保護(hù)配件電弧光保護(hù)裝置源頭廠家。</p><div

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、低壓母線沒(méi)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(mén)為解決這些問(wèn)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 、10KV及0.4KV的電壓等級(jí)，既可以分散在開(kāi)關(guān)柜就地安裝，也可以集中組屏安裝，提供以太網(wǎng)、RS485通訊接口，可以和其它保護(hù)、自動(dòng)化設(shè)備一起，通過(guò)通信接口組成自動(dòng)化系統(tǒng)。</p><p> 1.1 電弧光產(chǎn)生的原因 </p> <p> 引起開(kāi)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(lái)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(kāi)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(guò)100 ms ，所釋放的能量開(kāi)始急劇增加，接著各種故障效應(yīng)對(duì)開(kāi)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 /> 穩(wěn)定性好，保護(hù)功能強(qiáng)大，母線弧光保護(hù)，廠家直銷。</p><div style="width:100%;text-align: center;"><img

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(guò)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(kāi)始，內(nèi)部壓力增加，由于過(guò)熱的空氣開(kāi)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_(kāi)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(kāi)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。高性能弧光保護(hù)裝置，廠家直銷。昆明開(kāi)關(guān)柜弧光保護(hù)</p><p

-----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>
