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(guò)檢測(cè)電流信號(hào)動(dòng)作于低壓斷路器短，這樣的說(shuō)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(tīng)聽(tīng)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(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> ----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(kāi)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(méi)有發(fā)生故障的回路； </p> <p> <br /> </p><p> 電弧光保護(hù)系統(tǒng)作用：電弧光保護(hù)系統(tǒng)具有非?？斓膭?dòng)作速度，對(duì)開(kāi)關(guān)柜各單元室的總故障清掉時(shí)間可控制在100ms以內(nèi)。因此，在發(fā)生弧光故障、柜內(nèi)壓力和溫度急劇增加以前，電弧光保護(hù)系統(tǒng)就可以發(fā)出跳閘指令切除供給的短路電流，使設(shè)備損壞及人員傷害的損失減到**小。 </p> <p> 對(duì)于中低壓開(kāi)關(guān)柜來(lái)講，以**快的速度切除故障意味著比較大限度地限制電弧燃燒釋放的能量，其益處是：1）保護(hù)附近工作人員免受電弧故障效應(yīng)的傷害；2）開(kāi)關(guān)柜內(nèi)部部件的限制到**??；3）很大減少開(kāi)關(guān)設(shè)備損壞的維修費(fèi)用；4）比較大限度地減少用戶停電時(shí)間，可盡快恢復(fù)生產(chǎn)；5）對(duì)于使用年限很長(zhǎng)需要進(jìn)行改造的開(kāi)關(guān)柜，采用電弧光保護(hù)可有效延長(zhǎng)其使用壽命，從而減少對(duì)開(kāi)關(guān)設(shè)備的投資費(fèi)用。 </p> <p> 電弧光保護(hù)作為中低壓母線保護(hù)，對(duì)配電系統(tǒng)還將提供以下益處：1）保護(hù)昂貴的主變壓器或廠用變壓器免受巨大的短路電流沖擊而損壞；2）防止波及站用直流系統(tǒng)，避免故障擴(kuò)大而造成經(jīng)濟(jì)損失。高壓弧光保護(hù)裝置，專(zhuān)業(yè)生產(chǎn)提供。</p><div

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(guò)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(guò)電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過(guò)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)。

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)椤半姎饩€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(wú)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)，對(duì)電氣線路將感應(yīng)瞬態(tài)過(guò)電壓”此時(shí)“芯線上感應(yīng)的瞬態(tài)過(guò)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。電弧光保護(hù)裝置廠家直銷(xiāo)，歡迎來(lái)電咨詢。河南弧光保護(hù)生產(chǎn)廠家</p><p
