目前南京、保定的生產(chǎn)廠家都是采用一體式的裝置，只有早起仿ABB、VAMP、UTU的廠家按照進(jìn)口產(chǎn)品的結(jié)構(gòu)模式做的，各個(gè)單元之間通過電纜連接，人為增加了節(jié)點(diǎn)，反而降低了設(shè)備的可靠性。zhidao </p> <p> 弧光保護(hù)的技術(shù)發(fā)源地在芬蘭。ABB的REA系列，Vamp的321,221系列，在國內(nèi)都有比較多的應(yīng)用，還有Arcteq、UTU 也都有較成熟的弧光保護(hù)產(chǎn)品。 </p> <p>

</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。滄州弧光保護(hù)配件紫外光弧光保護(hù)，廠家直銷。</p><div

什么是弧光放電？ </p> <p> 當(dāng)兩電極間電壓升高時(shí)，在電極**近處空氣中的正負(fù)離子被電場加速，在移動的過程中與其它空氣分子碰撞產(chǎn)生新的離子，這種離子大量增加的現(xiàn)象稱為“電離”?？諝獗浑婋x的同時(shí)，溫度隨之急劇上升產(chǎn)生電弧，這種放電稱為弧光放電?；」夥烹娨话悴恍枰芨叩碾妷?，屬于低電壓大電流放電。 </p> <p> 弧光放電產(chǎn)生的條件是小間隙和大電流，如果增加間隙或減小電流，電弧將會消失。 </p> <p> <p> 電弧光是怎樣形成的？ </p> <p> 電弧性短路起火：如將兩電極接觸后再拉開建立了電弧，則維持此10mm 長的電弧只需20V 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> 易維護(hù)弧光保護(hù)，專業(yè)提供，歡迎來電咨詢。</p><div style="width:100%;text-align: center;"><img

電弧光保護(hù)目的是在發(fā)生電弧故障時(shí)，通過限制電弧燃燒時(shí)間來保護(hù)附近工作人員及設(shè)備。電弧保護(hù)首先必須檢測故障電弧，然后才能切斷流過的故障電流。在中低開關(guān)柜內(nèi)部故障保護(hù)中，一般是通過跳開斷路器來切除故障使故障電弧熄滅。電弧燃燒時(shí)伴隨著光、聲及電磁波形式的輻射。通過分析可見光、聲波、紅外線或無線電頻率的輻射可以檢測到電弧的存在，甚至連由電弧產(chǎn)生的壓力波也已經(jīng)用來檢測它的存在。然而，*****使用的方法還是通過檢測可見光來實(shí)現(xiàn)。
