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(shí)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(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作的時(shí)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(shí)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(kuò)大化，防城港母線弧光保護(hù)，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，防城港母線弧光保護(hù)，防城港母線弧光保護(hù)，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，傳感器的檢測會不會誤動作，跳閘沒有發(fā)生故障的回路；

的電壓。也就是說只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導(dǎo)體間的電弧、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電。 </p> <p> 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，在這種情況下可能建立電弧?！坝秩缇€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)。”
