摘要
运用传热学基本原理和经典试验换热准则式,推导得出浸油变压器平均油温升和顶油温升的计算式。并依此计算了一款三相油浸式变压器的平均油温升和顶油温升,计算结果与试验结果较为吻合,表明本计算方法在工程中应用可靠。
By utilizing the fundalmental theory of heat transfer and the classical experiment heat transfer correlation equations, the calculation methods on the mean oil temperature rise and top oil temperature rise of the oil-immersed power transformers are obtained. The calculation results and the experimental results of the mean oil and top oil temperature rises of a three-phase oil-immersed power transformer are compared and analyzed, which shows they are in relatively good agreement, so that the calculation methods are reliable for engineering applications.
