摘要
通过计算机数值模拟的方式,对海上升压站可能发生的火灾工况进行分析。设置二层甲板主变室及GIS室起火的工况,分析火灾烟气蔓延情况、站内通道安全性以及钢结构安全性。模拟发现该类火灾发展十分迅速,而远离陆地导致外界力量很难及时干预,其消防策略应当注重于对火灾的预防和初起火灾的尽早响应。提出使用排油注氮灭火系统、加设灭火器、对主变室的顶部进行防火涂装以及消防管理方面的建议。
Computer simulations about fires in an offshore substation were presented.The fires were set in main transformer chamber on tween deck and in GIS room.The smoke spread,safety of passage way in station and the safety of steel structure were analyzed.The results showed that the fires grow extremely rapidly and firemen can hardly reach it on time,thus the fire protection must be focused on fire prevention and suppressing early fires.Consequently,advice about oil-drain and nitrogen-filling fire extinguishing system,fire extinguisher,fire retardant coating on top of the main transformer chamber and management was proposed.
