有人提倡在低壓柜內(nèi)安裝弧光保護(hù)裝置，低壓柜內(nèi)一旦發(fā)生短路故障，弧光傳感器能立馬檢測(cè)到弧光信號(hào)，動(dòng)作于低壓斷路器，時(shí)間會(huì)比傳統(tǒng)的通過檢測(cè)電流信號(hào)動(dòng)作于低壓斷路器短，這樣的說法有道理嗎？低壓柜內(nèi)與中壓柜內(nèi)安裝弧光保護(hù)裝置有何區(qū)別呢？先聽聽大家怎么看，稍后我也會(huì)給出我的看法 </p> <p> <br /> </p> <p> 本帖***由 bzp4891 于 2016-5-19 12:02 編輯 </p> <p> 1、首先動(dòng)作時(shí)間是否能保證在***擴(kuò)大前切除電源？這個(gè)不清楚 </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***也無法及時(shí)切斷電源。這種檢測(cè)方式適用于固定柜。 </p> <p> ----弧光傳感器**合適的位置我認(rèn)為在主母線室內(nèi)，用于主母線發(fā)生短路故障情況下切斷主開關(guān)以防止***擴(kuò)大化，如果非要安裝在饋線柜例如抽屜柜或固定分隔柜的電纜室，一是安裝的傳感器的數(shù)量很多成本難以承受，二是如果抽屜回路的某一個(gè)回路發(fā)生，傳感器的檢測(cè)會(huì)不會(huì)誤動(dòng)作，跳閘沒有發(fā)生故障的回路；

目**80伏/1千伏/3千伏/6千伏/10千伏/35千伏開關(guān)柜中沒有**的母線主保護(hù),但在國(guó)外電力行業(yè)已經(jīng)普及95%以上;國(guó)內(nèi)采用變壓器過流保護(hù)用于母線后備保護(hù),理論上必須延時(shí)300~500毫秒,實(shí)際上動(dòng)作時(shí)間可能長(zhǎng)達(dá)1.5~2秒,起不到對(duì)母線的真正保護(hù),并且使變壓器低壓側(cè)絕緣有較大的結(jié)構(gòu)性損壞,所以目前的母線后備保護(hù)是有缺點(diǎn)的 </p> <p> 從弧光保護(hù)設(shè)計(jì)的系統(tǒng)可靠性來看,變壓器、進(jìn)線、饋線都有主保護(hù),唯獨(dú)母線沒有**的主保護(hù),我們認(rèn)為母線應(yīng)該增加**主保護(hù)。雖然母線故障出現(xiàn)概率較低,但一旦出現(xiàn)將損失慘重。因此,從技術(shù)、設(shè)計(jì)方面建議配置母線**主保護(hù)弧光保護(hù),以確保操作人員的人身安全及系統(tǒng)的安全、穩(wěn)定運(yùn)行。

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)椤霸陔姎饩€路施工中，穿鋼管拉電線時(shí)帶電導(dǎo)體絕緣外皮之間并無因相對(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)，它對(duì)電氣線路將感應(yīng)瞬態(tài)過電壓”，此時(shí)“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(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。 </p> <p> 爬電起火：爬電是指電弧不是建立在空氣間隙中的電弧，而是出現(xiàn)在設(shè)備絕緣表面上的電弧。例如電源插頭的絕緣表面上的一個(gè)或多個(gè)相線插腳和PE線插腳，它們之間的絕緣表面可能發(fā)生爬電。紫外光弧光保護(hù)，廠家直銷。</p><div style="width:100%;text-align: center;"><img

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（如相線與中性線）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程，這種情況下可能建立電弧。又如線路絕緣水平嚴(yán)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(xiǎn)遠(yuǎn)大于上述金屬性短路的起火危險(xiǎn)。
