摘要
利用ANSYS软件建立了高性能厚膜熔断器的有限元模堑,并对其在正常工作状态下的瞬态温度场变化过程进行了数值模拟,得到熔断器引脚温升为65.30℃,电阻为0.05719Ω,发热功率为0.91504W等参数,并进行了实验验证。结果表明:实验和数值模拟的误差率为3.00%-4.00%,为熔断器的设计制造提供了方法和理论依据。
To establish the finite element model of high performance thick film fuse, a numerical simulation was performed for its change process of instantaneous temperature field at normal work status by ANSYS software. 65.30 ℃ of the temperature rise for the fuse lead, 0.057 19 Ω of resistance and 0.915 04 W of heating power were gained and verified by experiments. Results show that the error rates between the numerical simulation and the experiments are 3.00% - 4.00%, providing a way and theoretical basis for the design and fabrication of the fuse.
