電弧光保護(hù)電弧光是通過(guò)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(qiáng)光和高壓波的形式。 </p> <p> 電弧光保護(hù)裝置主要作用： </p> <p> 1、減少或降低電弧光對(duì)于人體的傷害，新鄉(xiāng)弧光保護(hù)接線。 </p> <p> 2、減少或降低電弧光短路故障對(duì)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(dòng)穩(wěn)定破壞，延長(zhǎng)變壓器的使用壽命。 </p> <p> 4，新鄉(xiāng)弧光保護(hù)接線，新鄉(xiāng)弧光保護(hù)接線、縮短電弧光故障切除時(shí)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(yùn)的時(shí)間，更快地恢復(fù)供電。專業(yè)提供饋線弧光保護(hù)系統(tǒng)，歡迎咨詢。新鄉(xiāng)弧光保護(hù)接線</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

中、低壓母線在發(fā)生短路故障、運(yùn)行人員誤操作和誤入帶電間隔等原因產(chǎn)生的電弧光對(duì)設(shè)備及人員造成的危害極大。電弧光使開(kāi)關(guān)設(shè)備內(nèi)的壓力和溫度迅速升高，如不及時(shí)切除，容易造成電纜護(hù)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(shí)，開(kāi)關(guān)設(shè)備劇烈震動(dòng)使固定件松動(dòng)脫落、甚至導(dǎo)致開(kāi)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(hù)，而是依賴上一級(jí)的后備過(guò)流保護(hù)切除母線故障，過(guò)流保護(hù)有延時(shí)，這就導(dǎo)致故障切除時(shí)間較長(zhǎng)，增加了設(shè)備的損害程度。電弧光保護(hù)系統(tǒng)原理簡(jiǎn)單、動(dòng)作迅速可靠，能夠有效減輕電弧光對(duì)設(shè)備和人身的傷害。母線弧光保護(hù)電源弧光保護(hù)裝置設(shè)計(jì)**，歡迎來(lái)電咨詢。</p><div

<br /> </p> <p> 第一種方法（采用壓力傳感器作為電弧光探測(cè)單元）壓力波是裝置內(nèi)出現(xiàn)電弧故障的效應(yīng)之一，將在電弧出現(xiàn)后的10-15毫秒后出現(xiàn)，可以安裝一些壓力傳感器用于探測(cè)壓力峰值。當(dāng)內(nèi)部的壓力達(dá)到設(shè)定值時(shí)，電弧監(jiān)測(cè)裝置發(fā)出動(dòng)作指令，控制開(kāi)關(guān)器件動(dòng)作。但是要預(yù)先確定電弧在柜內(nèi)產(chǎn)生的過(guò)壓值并非易事。 </p> <p> <br /> </p> <p> 第二種方法（采用光纖傳感器作為電弧光探測(cè)單元）弧光監(jiān)測(cè)器的操作邏輯如下：電弧現(xiàn)象會(huì)產(chǎn)生強(qiáng)烈的光輻射，因此柜體內(nèi)出現(xiàn)的弧光可以被弧光傳感器探測(cè)到當(dāng)弧光監(jiān)控系統(tǒng)探測(cè)到故障，會(huì)發(fā)出動(dòng)作信號(hào)給斷路器。這種方法的探測(cè)反應(yīng)時(shí)間*為1毫秒?；」鈧鞲衅鞣譃榭煞譃殡娏餍秃凸饫w性（可見(jiàn)光和紫外光）其中支持可見(jiàn)光的弧光傳感器有基頓電氣JD9900B系列弧光傳感器。

采用了可靠的快速算法，可以在短時(shí)間內(nèi)判斷弧光變化信號(hào)和電流變化信號(hào)并迅速出口，從發(fā)現(xiàn)故障到出口跳閘時(shí)間間隔優(yōu)于10ms，確保開(kāi)關(guān)柜內(nèi)設(shè)備的弧光在75ms以內(nèi)切除。 </p> <p> 2、全數(shù)字化設(shè)計(jì) </p> <p> 本裝置采用全數(shù)字化設(shè)計(jì)，配置靈活，動(dòng)作精度高，而且排除了由于旋鈕或其他機(jī)械設(shè)計(jì)導(dǎo)致的誤差***。 </p> <p> 3、保護(hù)原理簡(jiǎn)單、合理 </p> <p> 根據(jù)弧光產(chǎn)生時(shí)的特點(diǎn)，裝置采用弧光和電流雙重判據(jù)，判據(jù)簡(jiǎn)單且可以有效的保證動(dòng)作的準(zhǔn)確性。 </p> <p> 4、強(qiáng)大的電氣性能 </p> <p>

電弧光保護(hù)系統(tǒng)由以下主要部件組成： </p> <p> 1）弧光保護(hù)主控單元：主單元為電弧光保護(hù)系統(tǒng)的控制中心，收集動(dòng)作信號(hào)并對(duì)收集的數(shù)據(jù)進(jìn)行處理、判斷、發(fā)出跳閘信號(hào)以切除故障。設(shè)備自帶四路輸出接口分別為弧光跳閘出口1、弧光跳閘出口2、弧光跳閘出口3、跳閘總出口4。設(shè)備支持ModBUS-RTU規(guī)約，可通過(guò)后臺(tái)對(duì)設(shè)備進(jìn)行參數(shù)設(shè)置、實(shí)時(shí)數(shù)據(jù)讀取、故障信息讀取、復(fù)歸等操作，方便組網(wǎng)運(yùn)行。 </p> <p> 2）采集單元：弧光采集單元與主控單元配合使用，是弧光保護(hù)系統(tǒng)的重要組成部分，主要用于采集故障弧光，并將判斷后的結(jié)果通過(guò)光信號(hào)傳遞給主控單元。單個(gè)弧光采集單元可以安裝,16個(gè)弧光探頭，根據(jù)系統(tǒng)的大小可以任意增減弧光采集單元的數(shù)量。弧光采集單元通常安裝在選定的開(kāi)關(guān)柜內(nèi)中，選擇的原則是保證該單元相關(guān)光纖用量盡量少。 </p> <p> 3）弧光傳感器：專門用于故障弧光采集，是無(wú)源的弧光探測(cè)傳感器，安裝在開(kāi)關(guān)柜的母線室內(nèi)或饋線柜內(nèi)電氣元件的連接處。當(dāng)發(fā)生弧光故障時(shí)，光照度大幅度增加，弧光傳感器直接將光信號(hào)傳給弧光采集單元或饋線保護(hù)單元。新鄉(xiāng)弧光保護(hù)接線</p><p
