数据中心电气消防若干问题探究

Discussion on Electrical Fire Fighting in Date Center

数据中心具有电缆大量聚集、带载不间断运行、主机房多无人值守等特点,火灾风险高于一般场所。本文着重对规范及图集中未提及或明确的预作用延迟自动喷水灭火系统、无下送风地板吊顶回风机房火灾自动报警系统探测器设置、柴油发电机储油间可燃气体探测系统、蓄电池室氢气浓度探测系统联动控制等实际工程中常见关键技术问题进行探讨和研究。

In view of the characteristics of the date center, such as a large number of cables, uninterrupted operation with load, and unattended computer room, the fire risk is higher than that in general places. The article emphasizes on the technical discussion over the electrical design which is not mentioned or specified in specifications and National standard drawings, such as pre-action sprinkler system, detector setting of automatic fire alarm system for ceiling return air machine room without lower air supply, combustible gas detection system of diesel generator oil storage room, automatic control of hydrogen concentration detection system in battery room, and etc.
