ABSTRACT

More and more CFD tools are used to investigate the gas flow behavior during the opening of the high-voltage circuit-breakers with the creation of an electric arc. Gas flow analysis and computation provide the engineers with the information about the gas behavior, the dielectric withstand, and the evolution of the high-temperature areas inside the chambers. Moreover, oriented softwares are extremely important since they could permit rapid investigation and optimization of different shapes of the circuit-breaker parts. The expected functionalities of this tool are: classic analysis of the gas flow, post-treatment of new fields coming from external data base, easy comparison of different configurations of apparatus for different calculated quantities, temporal analysis, video creation, pseudo 3D representation, and parallel analysis of experimental data. The objective of the development at the Switchgear Research Centre of AREVA T&D was to extend this interface, to integrate CAD tools and to interface with other softwares. A first version of such a tool is now available. It has been developed thanks to the software Express from Advanced Visual System Company.
