摘　　要：分析了采用冷却器的变压器冷却系统存在的缺陷,提出了现场改造方案,对比了新旧冷却系统优劣,并通过改造实例验证改造后的冷却系统更有利于变压器安全、可靠运行。This paper analyzes the defects existing in the cooling system of the transformer with a cooler and puts forward the on-site reformation program. Comparing the advantages and disadvantages between the new and the old cooling systems,it confirms with an experiment that the reformed one is more conducive to the safe and reliable operation of the transformer.
