摘　　要：以换流变压器站变压器燃爆防控及消防应用为背景,针对变压器在失控条件下可能发生的燃爆事故,通过设计模拟试验,完成变压器燃爆事故的模拟。进而对现有消防设备消防炮的功能可靠性和抗爆性能进行验证。结果发现,在高温、高压的气云爆炸火球范围内,消防炮的抗爆性能无法满足实际需要,在变压器爆炸后存在功能损失的情况。发现了消防炮自身的抗爆薄弱环节,提出了消防炮抗爆设计及安装改进建议。可为换流变压器站的抗爆型消防炮设计提供基础数据参考。In converter transformer stations,transformers may experience explosion accidents under uncontrolled conditions.By simulating transformer explosion accidents through experiments,the reliability and anti-explosion perfor-mance of the fire cannon were verified.It was found that,within the range of high-temperature and high-pressure gas cloud explosion fireballs,the anti-explosion performance of fire cannon cannot meet practical needs.There is a loss of function after the explosion of the transformer.Weak links in the explosion resistance of the fire cannon were identified,and suggestions for the explosion resistance design and installation improvement of the fire cannon were proposed.It could provide conferences for the design of anti-explosion fire cannon in converter transformer stations.
