500kV变电站主变压器水喷雾设计

Design of the Water Spray System for the Main Transformers in a 500kV Substation

在条件允许的情况下,单台容量为125 MVA及以上的油浸式变压器大多采用水喷雾灭火系统。以某500 kV变电站为例,基于规范规定,对消防水泵流量和扬程的确定、喷头的布置和控制方式进行详述,为相关变电站主变压器水喷雾设计提供参考。

When conditions permit,most oil-immersed transformers with a capacity of 125 MVA and above use water spray fire extinguishing systems.Taking a 500 kV substation as an example,according to the regulations,the determination of the flow and head of the fire pump,the arrangement and control method of the sprinkler head are described in detail,so as to provide a reference for the design of water spray for the main transformer of the relevant substation.
