中文摘要: 综合考虑了变压器油物性参数随温度的变化和变压器辐射散热的边界条件,采用ANSYS软件对一台630 kW/10 kV自然油循环油浸式变压器的温度场进行了仿真分析.仿真结果表明:随着负载的增加,绕组温度急剧上升,且热点位置基本处于绕组相对垂直高度的85%左右.
Abstract:Based on the boundary condition of transformer's oil parameter and transformer radiation heat loss, ANSYS is used to conduct simulation analysis of a 630 kW/10 kV transformer with nature cycle-oil cooling method. A conclusion can be made from simulation result that with the increase of load, the winding temperature increases sharpest, and hot spot is located at the 85% vertical height.
