摘　　要：介绍油浸式变压器的散热方式、结构、原理,结合工程实践分析强迫油循环导向冷却散热器油管路出现异常后,依据油流继电器设计规范和潜油泵运行特性及油管路特性,得出冷却油路油量不稳定导致油流继电器抖动的原因。The heat dissipation mode,structure,and principle of the oil-immersed transformer are introduced.After analyzing the abnormality of the forced oil circulation guide cooling radiator oil pipeline in combination with engineering practice,according to the oil flow relay design specification,the operating characteristics of the submersible pump and the oil pipeline characteristics,the reason for the unstable oil flow of the cooling oil circuit causing the oil flow relay jitter is obtained.

关 键 词：变压器 散热 冷却油路 油量 油流继电器
