摘要
应用双标量磁位的表面阻抗法计算了一台电力变压器的三维漏磁场,将计算的漏磁通密度和铁芯拉板的最高温升与测量值进行了比较,结果能满足工程设计要求。分析了铁芯拉板的宽度、开槽数及变压器负载电流对拉板涡流损耗和最高温升的影响。
The 3D leakage magnetic field in a transformer is calculated by using the surface impedance method based on two scalar magnetic potentials.The leakage magnetic flux density and the highest temperature rise calculated of the tie plate are compared with the measured values,and the results are satisfied for engineering design.The influences are analyzed of the width and the slot number of the tie plate and the transformer load curent to the eddg current losses and the highest temperature rise.
