A Method for Obtaining the Electric Arc Model Parameters for SF6 Power Circuit Breakers

چکیده
Abstract: In this work, a new method for calculating the parameters of electric arc model for SF6 power circuit breaker is proposed. The methodology consists in the optimization of a theoretical function with respect to a group of model parameters in order to achieve a better approximation to a set of experimental data. The theoretical function is an asymptotic solution of the equation for the electric arc model obtained in a selected period of time. The developed method is applied to calculate the parameters of an arc model previously published in the literature. By using the variation of the cooling power, an improved electric arc model is also obtained including its parameters. The new model has a very compact form and exhibit a good correlation between voltage curves measured and calculated.
