真空箱滅弧室(shi)的關(guan)閉(bi)(bi)了了體統基本(ben)由關(guan)閉(bi)(bi)了了筒，關(guan)閉(bi)(bi)了了罩和各種元件組成(cheng)了。

屏蔽系統的主要作用是：

1.嚴(yan)防觸(chu)頭(tou)在燃弧期間中有許(xu)多的五金(jin)蒸氣(qi)和液滴噴濺，生成的污染絕緣性(xing)帶底殼(ke)的罐壁，防止(zhi)生成重力作(zuo)用(yong)滅弧室底殼(ke)的絕緣性(xing)帶剛(gang)度越(yue)來越(yue)低(di)或有閃絡。

2.有(you)所改善正(zheng)空(kong)滅弧(hu)空(kong)間內部的電磁場(chang)分(fen)布范圍，重要(yao)于正(zheng)空(kong)滅弧(hu)室耐(nai)壓塑料殼的中(zhong)型化，特別是(shi)(shi)在是(shi)(shi)來說高電壓電流的正(zheng)空(kong)滅弧(hu)室中(zhong)型化有(you)顯著治療效果。

3.吸附(fu)一(yi)部(bu)電(dian)(dian)(dian)(dian)(dian)影分焊弧(hu)(hu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)能(neng)，氣液(ye)分離器焊弧(hu)(hu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)生(sheng)產(chan)物(wu)。很是蒸空滅(mie)弧(hu)(hu)室在開(kai)(kai)斷(duan)短路等問題電(dian)(dian)(dian)(dian)(dian)流大(da)小時(shi)，焊弧(hu)(hu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)生(sheng)產(chan)生(sheng)的(de)(de)(de)熱(re)能(neng)工程(cheng)大(da)部(bu)門(men)被屏(ping)弊(bi)系統所(suo)吸附(fu)，善于于增(zeng)進觸(chu)頭間的(de)(de)(de)媒介修復的(de)(de)(de)強(qiang)度(du)。屏(ping)弊(bi)系統吸附(fu)焊弧(hu)(hu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)生(sheng)產(chan)物(wu)的(de)(de)(de)量越大(da)，代表(biao)他吸附(fu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)也越大(da)，這對增(zeng)強(qiang)蒸空滅(mie)弧(hu)(hu)室的(de)(de)(de)開(kai)(kai)斷(duan)儲電(dian)(dian)(dian)(dian)(dian)量起正常功用(yong)。
