Abstract

The motion of an arc plasma in a quenching chamber has a significant influence on the interruption performance of low-voltage switching devices (LVSDs). It is necessary to build an arc modelling tool, which can predict an arc behavior during an interruption process, to save development cost and time. This paper presents a numerical model of an arc plasma in LVSDs, which can reduce complexity and calculation load of an arc simulation by avoiding fully coupled modelling between fluid dynamics, and electromagnetism. There are two steps in the proposed arc modelling; the first is the finite element analysis of Lorentz force generated by nonlinear ferromagnetic material and current path in a quenching chamber, the second is the finite volume analysis of arc motion with consideration for fluid dynamics and heat transfer. This arc modelling also takes into account a contact motion, potential drops in the sheath layers of splitter plates and plasma radiation. It is shown that the simulated result has a similar trend with experimental data in terms of the arc motion as well as current and voltage waveforms.
