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(cè)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(cè)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(cè)它的存在。然而，*****使用的方法還是通過檢測(cè)可見光來實(shí)現(xiàn)。 </p> <p> 電弧光保護(hù)系統(tǒng)通過檢測(cè)開關(guān)柜內(nèi)部發(fā)生故障時(shí)發(fā)出的電弧光判斷是否發(fā)生故障。弧光是電弧**明顯且變化**快的特征物理量，因而電弧光保護(hù)具有超高速的動(dòng)作性能，整套保護(hù)的動(dòng)作時(shí)間可保證在幾毫秒以內(nèi)。對(duì)于開關(guān)柜內(nèi)部故障保護(hù)來講，這種超調(diào)整動(dòng)作性能是**重要的。為了避免外界光干擾可能引發(fā)系統(tǒng)的誤跳閘，在實(shí)際應(yīng)用中往往還引入過流閉鎖信號(hào)，即：只有同時(shí)檢測(cè)到弧光信號(hào)及過流動(dòng)作信號(hào)才發(fā)出跳閘指令切除故障，從而進(jìn)一步提高保護(hù)系統(tǒng)動(dòng)作的可靠性。 </p><p> 電弧光保護(hù)裝置的主要作用 </p> <p> 1、減專少或降低電弧光對(duì)于人體的傷害。 </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、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)屬間，更快地恢復(fù)供電。 </p> <p> 主要應(yīng)用于以下場(chǎng)合 </p> <p> 1、電力變電站。 </p> <p> 2、火電廠電氣段開關(guān)柜母線室及饋線柜。 </p> <p>

加上斷路器動(dòng)作時(shí)間，差動(dòng)保護(hù)和無時(shí)限電流速斷保護(hù)動(dòng)作，故障切除時(shí)間約100ms。即使電流速斷保護(hù)比弧光保護(hù)多40ms,查看弧光危害示意圖，電纜已經(jīng)燃燒。如果是帶時(shí)限電流速斷保護(hù)延時(shí)100ms、過電流Ⅰ段延時(shí)300ms,已經(jīng)達(dá)到柜體燃燒甚至的可能。工業(yè)用弧光保護(hù)裝置，專業(yè)提供。四川弧光保護(hù)多少錢</p><p
