【摘要】 针对隔爆型电气设备进行外耐压试验时内装电气部件等效模型材质对其爆炸特性的影响，选取金属和非金属材质的等效模型，通过实验分析了等效模型材质对隔爆外壳最大爆炸压力、最大爆炸压力上升速率和最大爆炸指数的影响，为隔爆外壳的检测提供了参考。更多还原

【Abstract】 Aiming at the influence of equivalent model material for internal electrical components on the flameproof enclosure performance during the pressure endurence test, the material of metallic and non-metallic are selected to do the test. The effects of materials on the maximum explosion pressure, pressure increase rate and the maximum explosion index of the enclosure are analyzed. It provides a reference for the test of flameproof enclosure.更多还原
