電弧光保護電弧光是通過電離的氣體（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、強光和高壓波的形式。 </p> <p> 電弧光保護裝置主要作用： </p> <p> 1、減少或降低電弧光對于人體的傷害。 </p> <p> 2、減少或降低電弧光短路故障對于設(shè)備的損害。 </p> <p> 3、避免變壓器因近距離母線故障造成動穩(wěn)定破壞，延長變壓器的使用壽命。 </p> <p> 4、縮短電弧光故障切除時間，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)備停運的時間，更快地恢復供電。 </p><p> 開關(guān)柜電弧耐受時間與電弧光保護動作時間 </p> <p> IEC298《交流金屬封閉開關(guān)設(shè)備與控制設(shè)備》附錄AA中規(guī)定的內(nèi)部燃弧測試時間是0.1秒。目前市場上銷售的開關(guān)柜基本上是按照IEC298標準生產(chǎn)的，也就是說開關(guān)柜可以承受的電弧燃燒時間為0.1秒。專業(yè)生產(chǎn)弧光保護，歡迎來電咨詢。</p> 弧光保護動作時間主要由兩部分組成：裝置動作時間和開關(guān)動作時間?；」獗Ｗo裝置的動作時間根據(jù)各廠商的動作原理不同（光電探頭或光纖探頭等）一般在1~10毫秒，開關(guān)動作時間（參考GE公司VB1—13.8真空斷路器）一般在50~60毫秒。故電弧光保護動作時間小于開關(guān)柜電弧耐受時間，不會對開關(guān)柜造成嚴重損傷。<div

目**80伏/1千伏/3千伏/6千伏/10千伏/35千伏開關(guān)柜中沒有**的母線主保護,但在國外電力行業(yè)已經(jīng)普及95%以上;國內(nèi)采用變壓器過流保護用于母線后備保護,理論上必須延時300~500毫秒,實際上動作時間可能長達1.5~2秒,起不到對母線的真正保護,并且使變壓器低壓側(cè)絕緣有較大的結(jié)構(gòu)性損壞,所以目前的母線后備保護是有缺點的 </p> <p> 從弧光保護設(shè)計的系統(tǒng)可靠性來看,變壓器、進線、饋線都有主保護,唯獨母線沒有**的主保護,我們認為母線應(yīng)該增加**主保護。雖然母線故障出現(xiàn)概率較低,但一旦出現(xiàn)將損失慘重。因此,從技術(shù)、設(shè)計方面建議配置母線**主保護弧光保護,以確保操作人員的人身安全及系統(tǒng)的安全、穩(wěn)定運行。中低壓弧光保護，專業(yè)提供，歡迎來電咨詢。大同弧光保護品牌</p><p
