摘　　要：采用Ansys热仿真模块Icepak对KYN44A-12型大电流开关柜内部温度场和空气流场进行了稳态仿真。分析了在夏季正常工作时的温度分布及内部空气流场分布,提出了散热和镀银触头温升控制结构优化方法,保障开关柜核心部件的温升达到国家行业标准,有利于延长使用寿命。通过热分析获取开关柜正常工作时的温度分布云图,为后续的设计及处在密闭空间的6个触头温升控制方案提供相关技术支持。Based on CAE software Ansys Icepak,the temperature and inner air flow distribution in the summer work condition were investigated by the steady thermal simulation. The issues on how to enhance the cooling efficiency and to control the temperature raising of six silver plating contacts were given,in which the temperature raising would reach the national industries standards,and the switch cabinet service life would be prolonged. The temperature and inner air flow contours captured in the steady thermal simulation will lay the foundation for cooling scheme design of six silver plating contacts installed in the sealed cells.
