Analysis of Discharge of Transmission Line in Sandstorm

Abstract:

A gas-solid flow model of transmission line surrounded by sand storm is built. Numerical simulation under different velocity, different sand diameter and different transmission line diameter situation is taken to obtain the volume fraction distribution of sand around the transmission line. Finite element-image method is chosen to build a sand-electricity coupling model made up of high voltage transmission line and sand around transmission line. Electric field distribution of transmission line with sand around it is obtained. Analysis results show that the model is effective.
