摘　　要：分析了牵引变压器温升模型,根据IEC354标准温升模型中变压器各部分稳态温升和暂态温升的计算公式,应用LabVIEW软件进行编程模拟,讨论了温升计算公式中的参数对牵引变压器温升曲线和寿命损失的影响程度,得出了变压器绕组对顶层油额定温升值所带来影响最大的结论。Analysis was made on the traction transformer temperature rise model. According to the calculation formula for transformer＇s every part stable temperature rise and instantaneous temperature rise in IEC 354 standard＇s temperature rise model, LabVIEW programming analog was carried out. Discussion was made on the degree of impacts on traction transformer temperature rise curve and life loss made by parameters in temperature rise calculation formula. The conclusion is that transformer windings will bring max impacts on top layer oil rated temperature rise value.
