摘要
以S11-M-500/35型配电变压器为研究对象,采用有限元方法对变压器铁芯及绕组进行多物理场耦合仿真计算,得到变压器在额定负载条件下的电磁特性和振动特征,并通过负载短路试验验证了仿真计算结果的准确性,可为变压器绕组变形状态诊断提供有效依据。
As the research object, S11-M-500/35 type distribution transformer studies that electromagnetic characteristics and vibration characteristics for the Sll-M-500/35 type power distribution transformer under the load conditions by using the finite element method to the multi-physics coupling calculation of the transformer core and windings. The accuracy of the simulation results is verified by the load short circuit test. The research results of this paper can provide technical means for transformer winding deformation diagnosis.
