Research on Improving Electric Field Distribution of UHV DC Line Arrester

UHV DC line arrester long length, there is a significant electric field distribution uniformity. This paper establishes a simulation analysis model for the electric field distribution of the UHV DC line arrester, and systematically studies the influence of measures such as adjusting the structure and the dielectric constant of the arrester valve disc on the electric field distribution of the arrester. It shows that the combination of different dielectric constants of arrester valves can significantly improve the electric field distribution of the arresters in UHV DC lines.
