摘要: 采用1∶1全尺寸特高压换流变压器实体火模型,开展添加水系灭火剂的水喷雾灭火系统灭特高压换流变压器全尺寸实体火的试验研究,提出已安装水喷雾灭火系统换流站的消防改造方案,以及水喷雾灭火系统抗烧和抗爆能力提升的解决方案,提升特高压换流变压器消防能力。结果表明,在美国防火协会标准的水喷雾灭火系统设计标准下,添加6%水系灭火剂的水喷雾灭火系统仅34 s就扑灭了全尺寸特高压换流变压器实体火,验证了添加水系灭火剂的水喷雾灭火系统的灭火能力。

Abstract: Using 1∶1 full-scale ultra-high voltage (UHV) converter transformer fire model,a water spray fire extinguishing system adding water extinguishing agent is developed to extinguish full-scale UHV transformer fire. A fire protection renovation scheme for the converter station which had installed the water spray fire extinguishing system and the solution to improve the fire resistance and knock resistance of the water spray fire-fighting system is proposed,which improves the extinguishing ability of UHV converter transformer.The test results show that under the standard of National Fire Protection Association for water spray fixed systems for fire,the water spray fire extinguishing system adding 6% extinguishing agent extinguishes the full-scale fire of UHV converter transformer in only 34 s,which verifies the fire extinguishing ability of the water spray fire extinguishing system adding water extinguishing agent.

Key words: UHV converter transformer, extinguishing agent, water spray system, extinguishing, converter station
