Research on the Influence of Voltage Polarity on Corona Discharge Characteristics of Insulators

摘要

The corona discharge of insulators has an important influence on the electromagnetic environment. In order to study the influence of different voltage polarities on the corona discharge characteristics of insulators, this paper is mainly based on the fluid-chemical reaction equation to establish a two-dimensional simulation model of insulators, which includes a variety of chemical reactions and substances. According to the above mentioned numerical analysis model, the electric field and the particle density of the insulators under different voltage polarities are given through the simulation calculation. Finally, the discharge parameters under different voltage polarities are compared, and the relationship between corona discharge parameters and voltage polarity is obtained.
