一、概述在石油、化工、煤矿、船舶等易燃易爆性物质集中的生产环境中 ,现场作业必须采用防爆电气产品。因此 ,准确可靠地进行防爆试验 ,测定防爆产品腔内的爆炸压力、动态强度和隔爆性能等成为至关重要的问题。为此 ,国家标准 GB3836.2—83《爆炸性环境用防爆电气设备 隔爆型
First, an overview In the oil, chemicals, coal, ships and other flammable and explosive materials concentrated production environment, field operations must use explosion-proof electrical products. Therefore, the accurate and reliable test of explosion-proof, determination of explosion pressure explosion-proof cavity products, dynamic strength and flameproof performance has become a crucial issue. To this end, the national standard GB3836.2-83 "Explosion-proof explosion-proof electrical equipment flameproof
