摘要
对油浸式电流互感器一次绕组换热特性进行了试验研究,得出了一次绕组表面对流换热准则关系式。通过试验得出了温升计算的重要参量———外表面与总热流的比值K1 和总热流、虹吸孔位置、绝缘厚度等因素的关系,为油浸式电流互感器的热设计提供了可靠的依据。
This paper presents an experimental investigation conducted by the authors in heat transfer characteristics of U-model primary windings of oil immersed current transformers.The non-dimensional heat transfer correlations is obtainded.The relationships among K 1(the ratio between the outer surface heat flow rate of insulation and the total heat flow rate),the total heat flow rate,the siphonic hole location and the thickness of insulation are determined respectively.This results can be used for thermal design in engineering practice.
