| 摘 要： | 为研究氢氩混合气（5%∶95%）在空气中爆炸时所对应氢、氧极限含量，按照爆炸性测试标准EN 1839—2017，测试氢氩混合气在与空气的总混合气体中不同占比时的可爆性。研究结果表明:氢氩混合气（5%∶95%）在总混合气体中体积分数为76.018%~86.029%时，总混和气体具有爆炸危险性,与之对应能够发生爆炸的最低氢气体积分数为3.8%，最低氧气体积分数为2.93%，不具有爆炸性的最高氧含量为2.72%，该值较ISO 10156—2017《气体和气体混合物-气瓶阀口选择用潜在燃烧性和氧化能力的测定》中规定的极限氧含量低，研究结果可为氢氩气与空气的混合气体爆炸事故预防提供新的参考。

| Abstract: | In order to find out the limiting hydrogen (oxygen) concentration corresponding to the explosion of hydrogen-argon gas mixture (5%∶95%) in air,according to the explosibility test standard EN 1839—2017,the explosibility of hydrogen-argon gas mixture within the different proportions was tested.The results showed that the hydrogen-argon gas mixture (5%∶95%) could form an explosive atmosphere when it accounted for 76.018%~86.029% in the mixture with air,corresponding to a minimum hydrogen percentage of 3.8%，a minimum oxygen percentage of 2.93% and the maximum oxygen content that is not explosive is 2.72% that could cause an explosion.The maximum oxygen content is lower than the limit oxygen content of 4.3% specified in existing relevant standards.The research results can provide a new reference for the prevention of hydrogen-argon-air gas mixture explosion accidents. |
