Review of Treatments for Suppressing Surface Charge Accumulation and Enhancing Surface Flashover Voltage
摘要
Abstract
The focus of this paper is to provide a comprehensive review of various insulation performance improvement methods for vacuum-solid and compressed air-solid interfaces. The surface characteristics of insulating materials have a significant impact on the flashover voltage along the surface. These surface characteristics include the surface resistivity
surface charge behavior
roughness
secondary electron emission coefficient
and intrinsic properties of the material. Numerous challenges remain to be explored and resolved concerning the causes and mechanisms of surface flashover
methods to increase flashover voltage
and their underlying physical principles. Therefore
the flashover phenomenon along the insulation surface and methods of increasing the flashover voltage have become challenging research key topics in related fields.
