滅弧技術(shù)原理
HD4斷路器利用(SF6)氣體作為滅弧和絕緣介質(zhì),氣體的熱膨脹性、負(fù)電性以及快速的復(fù)合作用使其成為滅弧的理想介質(zhì)。HD4斷路器是基于熱膨脹和壓氣助吹相結(jié)合的滅弧原理,該技術(shù)早已在高壓開關(guān)領(lǐng)域中廣泛成熟的應(yīng)用。其具有非常平滑的開斷特性,在開斷電流時(shí)不會(huì)出現(xiàn)截流現(xiàn)象,因此不會(huì)產(chǎn)生操作過電壓。優(yōu)良的特性確保了HD4斷路器具有很長的電氣壽命,并且避免對(duì)運(yùn)行中的負(fù)載設(shè)備造成沖擊。

由于采取這些措施,HD4斷路器和其附件均滿足以下標(biāo)準(zhǔn)的考核:

GB/T 2423.4(試驗(yàn)Db:交變濕熱(12 h+12 h循環(huán))
海拔高度
空氣的絕緣性能隨著海拔的升高而下降,因此在海拔條件下使用時(shí)必須考慮到此現(xiàn)象對(duì)開關(guān)外絕緣的影響,滅弧室內(nèi)部的絕緣不會(huì)受到任何影響,因?yàn)槠浣^緣能力是由SF6氣體保證的。如果開關(guān)柜安裝在1000 m海拔以上的地區(qū),在絕緣部件的設(shè)計(jì)階段應(yīng)該考慮到海拔高度的影響。
例:
• 安裝海拔: 2000 m
• 額定電壓: 40.5 kV
• 工頻耐受電壓: 95 kV
• 雷電沖擊耐受電壓: 185 kV
• Ka系數(shù),從圖表中查得: Ka=1.13
從上述參數(shù)可得,元器件必須能夠耐受(海拔零米高度處的試驗(yàn)條件):
• 工頻耐受電壓: 95x 1.13=107.35 kV
• 雷電沖擊耐受電壓: 185x1.13= 209.05 kV
