中、低壓母線在發(fā)生短路故障、運行人員誤操作和誤入帶電間隔等原因產(chǎn)生的電弧光對設(shè)備及人員造成的危害極大。電弧光使開關(guān)設(shè)備內(nèi)的壓力和溫度迅速升高，如不及時切除，容易造成電纜護套著火和母線熔毀，并且產(chǎn)生大量有害氣體傷害呼吸系統(tǒng)、高溫灼傷皮膚和刺傷眼睛。短路故障時，開關(guān)設(shè)備劇烈震動使固定件松動脫落、甚至導(dǎo)致開關(guān)柜造成人員傷亡。中低壓母線系統(tǒng)中一般不配置**的快速母線保護，而是依賴上一級的后備過流保護切除母線故障，過流保護有延時，這就導(dǎo)致故障切除時間較長，增加了設(shè)備的損害程度。電弧光保護系統(tǒng)原理簡單、動作迅速可靠，能夠有效減輕電弧光對設(shè)備和人身的傷害。 </p><p> 電弧光保護電弧光是通過電離的氣體（空氣）在帶電體和地之間或帶電體之間的短路。高能量的電弧光故障表現(xiàn)為電氣。它們釋放了大量的能量，表現(xiàn)為輻射、熱、強光和高壓波的形式。 </p> <p> 電弧光保護裝置主要作用： </p> <p> 1、減少或降低電弧光對于人體的傷害。 </p> <p> 2、減少或降低電弧光短路故障對于設(shè)備的損害。 </p> <p> 3、避免變壓器因近距離母線故障造成動穩(wěn)定破壞，延長變壓器的使用壽命。 </p> <p> 4、縮短電弧光故障切除時間，避免波及站內(nèi)直流系統(tǒng)造成重大損失。 </p> <p> 5、減少因電弧光故障造成設(shè)備停運的時間，更快地恢復(fù)供電。弧光保護裝置，弧光保護傳感器專業(yè)生產(chǎn)，歡迎來電咨詢。</p><div

當兩電極間電壓升高時，在電極**近處空氣中的正負離子被電場加速，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”。空氣被電離的同時，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> 紫外光弧光保護，廠家直銷。北海弧光保護圖紙</p><p style="text-indent:25px">智能電弧光保護裝置**，廠家直銷，歡迎咨詢。北海弧光保護圖紙</p><p>
