</p> <p> 溫度:電弧的溫度可以達(dá)到約為7000-8000°C </p> <p> 聲音:電弧發(fā)出的聲音強(qiáng)度高達(dá)160db(***聲發(fā)出的爆破聲*為130db)。 </p> <p> <br /> </p> <p> 折疊電弧光的危害 </p> <p> 開關(guān)設(shè)備內(nèi)部間隔發(fā)生故障而產(chǎn)生的電弧光會造成開關(guān)設(shè)備中的壓力和溫度迅速增加，如不及時切除、將可能造成以下重大危害: </p> <p> 電弧光中心溫度(相當(dāng)于太陽表面溫度的2~4倍，約為10000~20000°C)過高導(dǎo)致銅排、鋁排熔毀氣化; </p> <p> 電纜熔毀，電纜護(hù)套著火; </p> <p> 開關(guān)設(shè)備劇烈振動，使固定元件松脫; </p> <p> 使上一級變壓器承受近距離短路沖擊，故障電流產(chǎn)生的電動力可能導(dǎo)致變壓器繞組變形引起匝間短路; </p> <p> 故障產(chǎn)生的弧光沖擊波以300m/s的速度爆發(fā)，可摧毀途中的任何物質(zhì)，若波及站內(nèi)直流系統(tǒng)導(dǎo)致全站直流失電，將造成無法彌補(bǔ)的重大損失; </p> <p> 燃燒產(chǎn)生的0氣體被人吸入會產(chǎn)生生命危險(xiǎn); </p> <p> 高溫灼傷皮膚，強(qiáng)光刺傷眼睛 </p> <p> 爆破音振損傷耳膜，肺臟;

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)生的電弧光對設(shè)備及人員造成的危害極大。電弧光使開關(guān)設(shè)備內(nèi)的壓力和溫度迅速升高，如不及時切除，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，開關(guān)設(shè)備劇烈震動使固定件松動脫落、甚至導(dǎo)致開關(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)，而是依賴上一級的后備過流保護(hù)切除母線故障，過流保護(hù)有延時，這就導(dǎo)致故障切除時間較長，增加了設(shè)備的損害程度。電弧光保護(hù)系統(tǒng)原理簡單、動作迅速可靠，能夠有效減輕電弧光對設(shè)備和人身的傷害。母線弧光保護(hù)廠家直銷。</p><div

src="https://tyunfile.71360.com/UploadFile/keaton/637255090210449219/7963429.jpg"></div><p> 電弧光保護(hù)目的是在發(fā)生電弧故障時，通過限制電弧燃燒時間來保護(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)用來檢測它的存在。然而，*****使用的方法還是通過檢測可見光來實(shí)現(xiàn)。 </p> <p> 電弧光保護(hù)系統(tǒng)通過檢測開關(guān)柜內(nèi)部發(fā)生故障時發(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)具有超高速的動作性能，整套保護(hù)的動作時間可保證在幾毫秒以內(nèi)。對于開關(guān)柜內(nèi)部故障保護(hù)來講，這種超調(diào)整動作性能是**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，即：只有同時檢測到弧光信號及過流動作信號才發(fā)出跳閘指令切除故障，從而進(jìn)一步提高保護(hù)系統(tǒng)動作的可靠性。電弧光保護(hù)裝置廠家直銷，歡迎來咨詢。無錫母線弧光保護(hù)</p><p
