A switching-off process very similar to those in real high-voltage self-blast circuit-breakers is emulated in a model chamber to study the arc properties by optical emission spectroscopy. The arc is operated in a chamber filled with SF$_6$ between a

The paper gives an overview on the basics of CFD arc simulation tools with respect to the simulation of the fluid mechanical processes in the interrupter unit of SF6 high-voltage circuit-breakers at no-load and short-circuit switching-off processes.

International audience; In this study a theoretical approach allows estimating the ablation mass flux of copper from a corrected Hertz-Knudsen flux. The influence of the copper vapours coming from the anode electrode to an SF 6 plasma is studied in a

A transient magneto-hydrodynamic model based on @Ansys-Fluent software applied on a high-voltage circuit breaker (HVCB) geometry is presented. The model is turbulent ( $\kappa $ – $\varepsilon $ realizable model), and radiation is taken into accoun

This paper deals with the utilization of an improved model for the PTFE-nozzle deformation caused by the ablation process in the simulation of on-load switching-off processes in high-voltage circuit breakers. In order to describe the plasma's behavio
