<p> 主配電柜或大型的電氣設(shè)備(如變壓器或發(fā)電機)附近短路能量高而且有故障產(chǎn)生時的電壓也很高。 </p> <p> 在柜體內(nèi)形成電弧的過程可分為四個階段: </p> <p> 壓縮階段:電弧占據(jù)了整個空氣空間，由于持續(xù)的釋放能量產(chǎn)生過熱，導(dǎo)致對流和輻射，保留在柜內(nèi)的空氣被加熱，在整個初級階段不同區(qū)域的溫度和壓力值不一樣。 </p> <p> 擴展階段: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而形成一個空洞。在這個階段其壓力達(dá)到比較大值，并因為熱空氣的釋放而開始減弱。 </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，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，可能不會出現(xiàn)上述某些階段或者只有較少的影響;然而，在電弧的周圍，會形成壓力波、并導(dǎo)致溫度的上升。 </p><p> 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到弧光信號，動作于低壓斷路器，時間會比傳統(tǒng)的通過檢測電流信號動作于低壓斷路器短，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、首先動作時間是否能保證在***擴大前切除電源？這個不清楚 </p> <p> -----這個有時間可以保證，而且這個時間確實很短，一般廠家通過實際驗證后給出斷路器與弧光保護(hù)裝置在故障情況下動作的時間； </p> <p> 2、圖中是固定分割或抽屜柜，安裝在動力電纜室內(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，抽屜或分隔內(nèi)和饋出線側(cè)發(fā)生的弧光短路***也無法及時切斷電源。這種檢測方式適用于固定柜。 </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回路發(fā)生，傳感器的檢測會不會誤動作，跳閘沒有發(fā)生故障的回路； </p> <p> <br />
