Abstract

The invention relates to the technical field of insulation, in particular to an application of a carbon-rich amorphous thin film in a high-voltage resistant insulating material. According to the application of the carbon-rich amorphous thin film, the surface roughness of the insulating material can be lowered; the microstructure surface planarization is achieved; and the flashover voltage is improved, so that the surface insulating property of the insulating material is greatly improved.

Description

technical field [0001] The invention relates to the technical field of insulation, in particular to the application of multi-carbon amorphous films in high-voltage-resistant insulating materials. Background technique [0002] Organic and inorganic materials are processed into high-voltage insulating materials with excellent processing properties or insulating properties. The test of high-voltage resistance of insulating materials is generally carried out by testing flashover voltage or breakdown voltage. Under the action of high voltage, destructive discharge occurs on the surface of insulating materials, and the voltage during discharge is called flashover voltage. After a flashover occurs, the voltage between the electrodes drops rapidly to zero or close to zero. Sparks or arcs in the flashover channel cause local overheating of the insulating surface and cause carbonization, which damages the surface insulation. This discharge along the surface of the insulator is calle...
