防爆大連配電箱是指正壓式密閉空間內的維護氣體高于外界大氣壓的原理，可以有用阻止外界爆破性氣體進入密閉空間或將密閉空間內開釋的爆破性氣體濃度稀釋到爆破極限以下完成其應用。

　　防爆大連配電箱氣(qi)(qi)(qi)路部分:它的(de)作用不僅是確(que)保快速通風，還要確(que)保工作時維持在(zai)正常的(de)正壓值。在(zai)快速通氣(qi)(qi)(qi)階(jie)段，能有用確(que)保z小通氣(qi)(qi)(qi)流量和(he)通氣(qi)(qi)(qi)時間，在(zai)正常使用時，用小流量維持正壓。當毛病產(chan)生時，有必要趕快排氣(qi)(qi)(qi)，使壓力保持在(zai)正常范圍內。
