摘要
对一台轴向分裂发电机变压器在半穿越运行工况下的电流分配进行了理论计算,通过3D有限元仿真分析验证了变压器在不对称运行条件下端部调压区域存在电流过流的情况,并提出了改善措施。
The current distribution of an axially split generator transformer under semi-penetrating condition is calculated.The overcurrent problem in the voltage regulating area at the end of transformer winding under asymmetric operation condition is verified by FEM,and the improvement measures are proposed.
