摘　　要：由于盐雾腐蚀的原因,通常将海上升压站电气设备布置在封闭的空间内。但由此带来设备的散热面临巨大挑战,尤其是散热量最大的主变压器。为此,对变压器自冷方式在海上升压站所面临的挑战进行分析,提出了一种变压器闭式循环水冷系统的设计方案。通过对两种方式进行的技术经济比较,得出了水冷方式比自冷方式更适合海上升压站的结论。As salt mist corrosion, electrical equipments of the offshore substation are usually arranged in an enclosed space. Howev- er, it will bring great challenges for the cooling of equipments, espacially the main transformers which have the most quantity of heat. This paper analyses the challenges for the ONAN transformers in the offshore substation, and gives a design of the closed cycle water cooling system for the transformer. By the comparison in technology and economy of the two schemes, the conclusion shows that the OFWF transformer is more suitable than ONAN transformer for offshore substation.
