摘要

本文通过在N S方程组中加入源项以考虑电弧效应的方法建立了一个电弧模型

数值方法采用Taylor galerkin有限元法。使用该模型对压气式SF6断路器的开断过程进行了数值模拟。计算模型考虑了移动的边界条件。给出了在不同开距下电弧温度分布、压力分布以及电弧电压等的数值计算结果

数值模拟结果与试验结果吻合

Abstract

An arc model based on the N S equations modified by adding an energy source term to take account of the arc is developed and solved using Taylor galerkin FEM in the present paper. The numerical method is applied to the simulation of the breaking process of a puffer type GCB. Moving boundary conditions of the arc chamber during operation is taken into account. Numerical predictions of the temperature profiles and pressure distribution at different strokes as well as the arc voltage are presented. The numerical results agree well with the experiment.
