对可燃气体(或蒸气)最大试验安全间隙值的测定方法进行了研究,设计了一套测定可燃气体(或蒸气)与空气混合物混合爆炸的最大试验安全间隙值的装置,用其所测数据与IEC标准中的推荐数据具有较好的可比性,为爆炸性气体(或蒸气)的分级、分组以及隔爆型电气设备的设计提供了理论依据。
A method for determining the maximum safe clearance of combustible gas (or vapor) was studied. A set of devices for measuring the maximum test clearance of combustible gas (or vapor) mixed with air mixture was designed. Using the measured data and IEC standards recommended data has better comparability, for the explosive gas (or vapor) grading, grouping and flameproof electrical equipment design provides a theoretical basis.
