電弧光保護系統(tǒng)使用先進的處理器技術來控制系統(tǒng)的功能，秦皇島高精度弧光保護。該處理器技術也使得電弧光保護系統(tǒng)功能的編程，可匹配開關柜的不同運行方式。在跳閘回路里采用的半導體技術（可控硅開關）確保了開關柜里的供電開關以**小的延時得到跳閘信號。在不論是KEATON電弧光保護系統(tǒng)的主控單元，還是電弧光單元探測到電弧光，并且電流單元的整定的電流定值被超過，電弧光保護系統(tǒng)的跳閘信號將在極短時間內(nèi)到達供電開關。 </p> <p> 電流的信息也可直接取自安全電流回路，在此情況下，電弧光保護也可盡可能快的得到過流的信息。如果偶爾光線信號超過光線設定值或者電流信號超過電流設定值，系統(tǒng)不會輸出跳閘信號，也不會記憶在跳閘回路中，但是在主控單元上會顯示報警信號。在編程的時候，需要考慮系統(tǒng)按照用戶所希望的方式正常工作，秦皇島高精度弧光保護。采用光纖技術來向主控單元傳輸跳閘信號，確保了電弧光保護系統(tǒng)的完美功能，秦皇島高精度弧光保護，它的抗干擾能力強，跳閘信號可以非常迅速的輸出到斷路器。弧光保護裝置廠家直銷，全國招商。秦皇島高精度弧光保護</p><div

300m/s 的速度爆發(fā)，摧毀途中的任何物質.。只要系統(tǒng)中不斷電，弧光就會一直存在。要想比較大限度的減少弧光的危害，我們需要一種安全、迅速而有效的半導體電弧光保護系統(tǒng)。在開關柜抽屜內(nèi)，弧光可以迅速的在 10ms內(nèi)達到 3m遠，因此要想很大程度降低損失，時間是個**主要的因素。KEATON電弧光保護系統(tǒng)輸出跳閘信號時間極短，即使在安裝或者維護的時候也能保護操作人員的安全。無錫弧光保護什么牌子好弧光保護生產(chǎn)廠家，歡迎來電咨詢。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

引起開關柜弧光短路故障的原因很多，主要有：絕緣故障、載流回路不良、外來物體的進入、人為操作錯誤、系統(tǒng)改變或故障等。 </p> <p> 1.2 電弧光的能量 </p> <p> 開關柜發(fā)生內(nèi)部弧光故障產(chǎn)生的短路功率可高達8~60 MW，所產(chǎn)生的能量與電弧的燃燒時間、短路電流的平方值、柜體幾何尺寸以及所使用的材料等因素有關，其中**主要的因素是短路故障電流及電弧燃燒的時間，電弧能量與有關電弧燃燒的時間的關系如圖所示。從圖中可以看出，電弧燃燒持續(xù)時間超過100 ms ，所釋放的能量開始急劇增加，接著各種故障效應對開關設備的電纜、銅排以及鋼材造成嚴重損壞. </p> <p> <br /> </p><p> 什么是弧光放電？ </p> <p> 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”?？諝獗浑婋x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芨叩碾妷海瑢儆诘碗妷捍箅娏鞣烹?。 </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體間的電弧、帶電導體與地之間的電弧和絕緣表面的爬電。 </p> 光電式電弧光保護，廠家直銷，歡迎咨詢。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
