摘　　要：外壳耐压试验的目的是验证外壳是否能承受内部的爆炸压力。对ⅡC类隔爆型防爆电气设备试验时产生的爆炸压力进行了分析,得出了对同一样品进行试验时,乙炔和空气混合物产生的爆炸压力较大,并用试验进行了验证。The object of tests of ability of the enclosure to withstand pressure is to verify that the enclosure can withstand the pressure of an internal explosion.This article analyzes the explosive pressure of ⅡC electrical apparatus during the tests.We come to the conclusion that the ethyne-air explosive mixture produces relatively higher pressure from a same sample,and test verification is carried out.

关 键 词：隔爆型 ⅡC 外壳耐压试验 爆炸压力
