Моделирование поражения стержня разрядом длинной искры с использованием многошаговой модели

Abstract

Building a multi-step model, which allows to calculate the probability of hitting the rod object of a long spark. The object is located in an electric field, which is formed in the electrode system "rod-plane". Confirmation of adequacy of the model to experimental data, which describe the probability of hitting in the rod objects. Methodology. Numerical simulation of movement long sparks from a point in space in the direction of the plane. Comparison of the results of modeling of the probability of defeat of a rod with a confidence interval, which is determined on the basis of experimental data. Results. Developed multistage model adequately describes the probability of defeat the rods objects. In the simulation, the discharge gap has a length of Н = 3 − 15 m. The adequacy confirmed by the case where the long spark begins to develop from a point on the axis of the rod object. Originality. For the first time propositioned a mathematical model to determine the probability of defeat the rod object, which is based on multi-step procedure traffic long spark. Practical value. The developed model allows to predict the probability of defeat the rod of objects a length to 6 m.
