基于ANSYS的高压开关柜热电耦合仿真与优化

Thermoelectric Coupling Simulation and Optimization of High Voltage Switchgear

高压开关柜是重要的电气设备,对电力系统的安全和高效运行起着非常重要的作用。柜内温升过高是造成开关柜失效的主要原因。基于热传导微分方程及辐射换热方程,对长城开关电器某型号开关设备建立了传导、对流和辐射换热相互耦合的数学模型。利用商用软件ANSYS对额定电流运行状态下的高压开关柜温度场分布进行了数值计算。最后研究了开关柜的优化和改进方案。

Based on heat conduction differential equation and radiation heat transfer equation,a mathematical model coupled with conduction,convection and radiative heat transfer is established for switchgear device.The ANSYS is used to calculate the temperature distribution of the switchgear under the operating state of the rated current.
