的電壓。也就是說只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導(dǎo)體間的電弧、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電。 </p> <p> 帶電導(dǎo)體間的電弧性短路起火：短路起火時有兩種可能，其一是兩導(dǎo)體（如相線與中性線）接觸時因短路電流產(chǎn)生的高溫，使接觸點金屬熔化，之后金屬熔化成團收縮而脫離接觸的過程，在這種情況下可能建立電弧?！坝秩缇€路絕緣水平嚴重下降，雷電產(chǎn)生的瞬態(tài)過電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過電壓都可能擊穿劣化的線路絕緣而建立電弧?！薄半娀⌒远搪返钠鸹鹞ｋU遠大于上述金屬性短路的起火危險?！?</p><p> 廠用/配電中壓開關(guān)柜為全廠輔機/供電系統(tǒng)的供電樞紐。在發(fā)生內(nèi)部故障時，是否能迅速地切除故障，對全廠/配電系統(tǒng)的安全運行至關(guān)重要。但是，按目前的保護方案，存在以下幾個問題： </p> <p> ① 中壓母線尚沒有配置任何專門的保護; 而是由進線開關(guān)的相關(guān)后備保護來兼顧的; </p> <p> ② 進線開關(guān)與出線開關(guān)的保護需要相互配合:一般速斷保護延時的級差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護的配合級差更是長達1 – 2秒。 </p> <p> 所以，廠用/配電系統(tǒng)中壓母線上所發(fā)生的任何故障都至少要延時切除。換句話說，現(xiàn)有的廠用中壓母線能在**早時間切除故障的保護還是個空白。可是，我們只要稍加注意，就會不難發(fā)現(xiàn)不論是中壓開關(guān)母線的上游還是下游的諸多電氣設(shè)備無一沒有配有快速保護。相比之下，我們恐怕很難有充分的理由來說明，中壓母線的安全性可靠性應(yīng)該受到這樣的懈怠。鑒于中壓母線的重要地位，任何故障的延時切除，都是我們極為不愿意看到的狀況。因為開關(guān)柜內(nèi)的各種故障，其短路電流所產(chǎn)生的電弧及其大量的高溫，使柜內(nèi)氣體急劇膨脹，可在極短的時間內(nèi)達到頂峰，嚴重危及人身和設(shè)備安全。

弧光保護裝置是母線型弧光保護系統(tǒng)中的主要保護設(shè)備。主要用來檢測分析故障信號、接收分析采集單元的弧光故障信號，并對兩種信號進行綜合分析判斷。在滿足跳閘條件時，發(fā)出跳閘指令以便切除故障。一般安裝在進線柜或緊鄰進線柜的開關(guān)柜的二次控制門板上。其主要的技術(shù)優(yōu)勢有以下幾點： </p> <p> 1、動作迅速可靠。 </p> <p> 2、全數(shù)字化設(shè)計。 </p> <p> 3、保護原理簡單合理。 </p> <p> 4、故障信息記錄準(zhǔn)確。 </p> <p> 5、多種輔助保護功能。 </p> <p> 6、強大的電氣性能。 </p> <p> <br /> 弧光保護裝置，可護展。滄州弧光保護圖紙</p><p

電弧光保護目的是在發(fā)生電弧故障時，通過限制電弧燃燒時間來保護附近工作人員及設(shè)備。電弧保護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現(xiàn)。
