要約
A real gas model of SF6 was implemented for numerical analysis of flow in SF6 high-voltage circuit breaker. The model was used in simulations of unsteady flow of SF6 gas through the nozzles of high-voltage circuit breakers for rated voltage of 420 kV after the current zero instant for 20 ms arcing time. The computer program for simulation of high-voltage circuit breakers, based on a simplified integral model, was used to simulate the interrupting process up to the current zero and 1 ms after. It's were used to calculate the boundary conditions for unsteady gas flow simulations in a CFD code and subsequent analyses and comparisons.
