src="https://tyunfile.71360.com/UploadFile/keaton/637255090209130859/8513785.jpg"></div><p> 電弧光保護(hù)與母線保護(hù) </p> <p> 電弧光保護(hù)是動作時(shí)間**短的母線保護(hù)。 </p> <p> 而為什么其他母線保護(hù)的動作時(shí)間那么長，因?yàn)椤氨Ｗo(hù)配合”。電弧光保護(hù)只要滿足“電弧”和“過流”等判據(jù)就可立即發(fā)出跳閘指令。而其他母線保護(hù)（參考西門子公司7SD和7SJ62綜保裝置）當(dāng)滿足“過流”判據(jù)后還必須等待下級負(fù)載的“無過流匯報(bào)”后才可以發(fā)出跳閘指令。因?yàn)橄录壺?fù)載短路和母線短路都會造成進(jìn)線開關(guān)“過流”，如果下級負(fù)載短路應(yīng)該讓下級負(fù)載開關(guān)來切除，母線短路則由母線進(jìn)線開關(guān)來切除。電弧光保護(hù)猶如手持尚方寶劍，而其他母線保護(hù)則就像一個(gè)團(tuán)隊(duì)，不敢輕舉妄動。 </p> <p> 總上所述，采用電弧光母線保護(hù)可以在現(xiàn)有開關(guān)柜的電弧耐受時(shí)間標(biāo)準(zhǔn)以內(nèi)切除弧光短路故障，從而比較大限度地保護(hù)了附近工作人員，使開關(guān)裝置等配電設(shè)備免受損壞，很大減少了設(shè)備維修費(fèi)用及維修故障所需的停電時(shí)間，因而具有明顯的經(jīng)濟(jì)效益，為理想的中壓母線保護(hù)解決方案。 </p><p> 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運(yùn)動而產(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，它對電氣線路將感應(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。電弧光保護(hù)專業(yè)生產(chǎn)，性能穩(wěn)定，歡迎來電咨詢。</p><div style="width:100%;text-align:
