摘要
导出了电力变压器绕组热点温度计算模型,该模型采用了基于底层油温的三层热路模型结构,把油粘度参量分离出来在线计算,计算负载损耗产生热量时考虑了温度的影响,试验结果表明该模型得出的数据比较接近实际数据。
The calculation model of the hot temperature of winding in power transformer is derived. The model has temperature of three-layer heat exchange circuit which is based on the bottom oil temperature. The parameter of oil viscosity is separated to calculate on-line. The influence of temperature is considered in calculation of the load heat dissi- pation. The test results show the data from the model are much more closed to the measured data.
