摘要

在对某高压限流型熔断器的结构进行合理简化

并针对实际情况提出相关假设的基础上

利用有限元分析软件ANSYS

建立了用于熔断器热电耦合瞬态温度场计算的三维有限元模型。该模型中考虑了材料物理性能参数以及熔断器表面对流换热系数随温度的变化

并利用ANSYS有限元分析软件对该熔断器在正常工作以及故障情况下的瞬态温度场变化过程进行了数值模拟

最后就不同结构参数对熔断器温升特性的影响进行了研究

为该型熔断器的设计制造以及工程分析提供了理论依据。

Abstract

A three dimensional（3D） thermoelectricity coupled finite element model to analyze the transient thermal behavior of the high voltage current limiting fuse is established by using ANSYS program.In this model

the simplification of fuse’s structure and some reasonable suppositions are presented to simplify the calculation.In order to obtain the exact transient temperature distribution of the fuse

the temperature dependent on material properties and heat transfer coefficients are taken into account.The variety process of the temperature distribution in the case of normal working and fault are obtained through the analysis.Finally

the effect of structure parameter to the thermal characteristics of the fuse is studied

and the result provides a theoretical basis for the design and engineering analysis.
