MasterpactMTE低壓空氣斷路器和負(fù)荷開(kāi)關(guān)產(chǎn)品簡(jiǎn)介2008
由于出現(xiàn)了結(jié)構(gòu)簡(jiǎn)單、滅弧性能良好和電壽命長(zhǎng)的六氟化硫斷路器,使得壓縮空氣斷路器的使用范圍縮小。但北歐等一些高寒地區(qū),由于SF6氣體液化和開(kāi)斷能力降低(降低20%左右)等原因,有些國(guó)家在高壓、超高壓電網(wǎng)中還在使用壓縮空氣斷路器。此外,大容量發(fā)電機(jī)斷路器,要求開(kāi)斷容量大,動(dòng)作迅速,還廣泛應(yīng)用壓縮空氣斷路器。
壓縮空氣斷路器的滅弧室主要由噴口組成。電弧在噴口處燃燒,利用噴口噴出的氣流對(duì)電弧的散熱作用來(lái)熄滅電弧.因此它是一種外能式滅弧裝置。其滅弧能力主要取決于噴口處氣體的流量與氣流速度。增大壓縮空氣的工作壓力是提高壓縮空氣斷路器開(kāi)斷能力的最有效措施。隨著工藝技術(shù)的提高,壓縮空氣斷路器的工作氣壓不斷提高,早期的工作氣壓多為1~2MPa(即10~20倍標(biāo)準(zhǔn)大氣壓),已普遍采用3~4MPa,個(gè)別產(chǎn)品可高達(dá)5~6MPa。
ABB Emax 空氣斷路器(固定式和抽出式)均有相同的高度和深度,可安裝在開(kāi)關(guān)柜中,其性能確保操作者的安全。例如:柜門(mén)關(guān)閉時(shí)可搖出斷路器,保護(hù)等級(jí)達(dá)到IP54,此外還帶有安全鎖和雙重絕緣。相與相之間、相與中性線(xiàn)之間完全絕緣,并可對(duì)滅弧室與主觸頭進(jìn)行完整檢查。
