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?；」馐请娀?*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)系統(tǒng)作用：電弧光保護(hù)系統(tǒng)具有非?？斓膭?dòng)作速度，對(duì)開關(guān)柜各單元室的總故障清掉時(shí)間可控制在100ms以內(nèi)。因此，在發(fā)生弧光故障、柜內(nèi)壓力和溫度急劇增加以前，電弧光保護(hù)系統(tǒng)就可以發(fā)出跳閘指令切除供給的短路電流，使設(shè)備損壞及人員傷害的損失減到**小。 </p> <p> 對(duì)于中低壓開關(guān)柜來講，以**快的速度切除故障意味著比較大限度地限制電弧燃燒釋放的能量，其益處是：1）保護(hù)附近工作人員免受電弧故障效應(yīng)的傷害；2）開關(guān)柜內(nèi)部部件的限制到**小；3）很大減少開關(guān)設(shè)備損壞的維修費(fèi)用；4）比較大限度地減少用戶停電時(shí)間，可盡快恢復(fù)生產(chǎn)；5）對(duì)于使用年限很長(zhǎng)需要進(jìn)行改造的開關(guān)柜，采用電弧光保護(hù)可有效延長(zhǎng)其使用壽命，從而減少對(duì)開關(guān)設(shè)備的投資費(fèi)用。 </p> <p> 電弧光保護(hù)作為中低壓母線保護(hù)，對(duì)配電系統(tǒng)還將提供以下益處：1）保護(hù)昂貴的主變壓器或廠用變壓器免受巨大的短路電流沖擊而損壞；2）防止波及站用直流系統(tǒng)，避免故障擴(kuò)大而造成經(jīng)濟(jì)損失。電弧光保護(hù)裝置，質(zhì)量可靠，性能穩(wěn)定。</p><div
