(1)主控單元用于管理、控制整套電弧光保護系統(tǒng)。它檢測故障電流和弧光信號，并對收到的兩種信號進行處理、判斷，在滿足跳閘的條件時，發(fā)出跳閘指令切除故障。 </p> <p> 主控單元有4個數(shù)據(jù)輸入接口，共可接入24個弧光單元或電流單元；輸出接口包括4路快速跳閘輸出和6路常規(guī)繼電器跳閘輸出共有4+16個弧光檢測口。當弧光信號輸入超過16個時。推薦采用弧光單元。主控單元根據(jù)弧光單元或者弧光傳感器輸送的信號，能準確地判斷故障點位置。 </p> <p> (2)電流單元用于檢測過電流信號，ABC三相電流均可檢測，電流單元檢測到的信號通過光纖和數(shù)據(jù)線傳到主控單元，主控單元依據(jù)設(shè)定的邏輯判斷是否發(fā)出跳閘指令。 </p> <p> (3)每個弧光單元包含10個弧光檢測接口，這些接口均為光纖接口，弧光保護品牌，用于連接弧光傳感器，弧光保護品牌，弧光保護品牌。弧光傳感器的感光強度則可以通過弧光單元面板上的電位計來調(diào)節(jié)設(shè)定，可以從10KLux調(diào)節(jié)至50Klux。弧光單元檢測到的信號通過光纖和數(shù)據(jù)線傳到主控單元，主控單元依據(jù)設(shè)定的邏輯判斷是否發(fā)出跳閘指令。 </p> <p> (4)弧光傳感器是探測弧光的感應(yīng)原件 </p> <p> (5)電源模塊工作電源為交直流兩用 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="弧光保護品牌"

style="text-indent:25px">電弧光保護和快速滅弧器電弧光保護，顧名思義，就是當發(fā)生電弧光故障時保護人員和電氣設(shè)備。目前市面上電弧光保護產(chǎn)品種類繁多，容易給我們造成混淆，典型產(chǎn)品就是“快速滅弧器”。其實“快速滅弧器”只是電弧光保護家族的一個分支，和傳統(tǒng)的電弧光保護還是存在本質(zhì)上的區(qū)別。他們的本質(zhì)區(qū)別就在于動作方式上。傳統(tǒng)的電弧光保護動作結(jié)果是切除上級斷路器，而快速滅弧器的動作結(jié)果則是將電氣一次主回路進行短路接地。如某品牌的“快速滅弧器”：由于快速滅弧器會對電氣一次回路甚至主變造成一定的損傷，而且該類產(chǎn)品存在“一家獨大”等情況，市面上的應(yīng)用率不是很高。

跳閘回路采用了快速繼電器技術(shù)，確保保護系統(tǒng)在1ms內(nèi)發(fā)出跳閘信號，加上斷路器動作時間(35-60ms)，使開關(guān)柜內(nèi)部電弧光故障總切除時間控制在60ms以內(nèi)，而且在外觀上無明顯損壞。繼電保護裝置包括測量、計算、自檢、動作等時間累計約44ms, 加上斷路器動作時間，差動保護和無時限電流速斷保護動作，故障切除時間約100ms。即使電流速斷保護比弧光保護多40ms,查看弧光危害示意圖，電纜已經(jīng)燃燒。如果是帶時限電流速斷保護延時100ms、過電流Ⅰ段延時300ms,已經(jīng)達到柜體燃燒甚至的可能。 </p><div style="width:100%;text-align: center;"><img
