摘　　要：本文探讨了电阻法测试绕组温升的方法。确定影响其不确定度的因素,其不确定度来自冷态电阻、热态电阻、试验开始时环境温度和试验结束时环境温度,由A类和B类不确定度合成。重点分析了拟合曲线对绕组温升测试结果值评判的影响。The paper discusses the resistance method to determine the temperature rise of the winding, and analyzes the factors affecting the uncertainty. The uncertainty comes from the resistances and the environment temperatures at the beginning and at the end of the testing which are composed of A type and B type. The paper also analyzes the influence of different fitted curves to the value of the temperature rise.
