Abstract

The invention discloses a rapid industrial surface conductivity processing method for a high-voltage DC basin type insulator. Tetraethyl orthosilicate (TEOS) mixed gas is ionized in a plasma jet tubeinto plasma, the plasma is injected to the surface of the DC basin type insulator to form different thicknesses of surface deposition, and the high-voltage DC basin type insulator with different surface conductivities is obtained. The surface of the high-voltage DC basin type insulator is processed, the surface conductivity in the processed position is increased, the surface electric field is unified, and the insulation performance of an epoxy resin material is improved substantially.

Description

technical field [0001] The invention belongs to the field of high-voltage equipment insulation preparation, and relates to a rapid industrialized surface conductivity treatment method for high-voltage DC basin-type insulators. Background technique [0002] In recent years, with the development of high-voltage and large-capacity power transmission in power systems, gas-insulated metal-enclosed switchgear (GIS) and gas-insulated metal-enclosed transmission lines (GIL) have advantages, has been widely concerned and applied. Among them, the pot insulator not only plays the role of mechanical support, but also acts as an electrical insulator, which plays a decisive key role in the safe and stable operation of the entire GIS and GIL. However, even in the demanding ±800kV DC UHV project, epoxy cast insulators still have frequent failures. [0003] It is generally believed that when GIS / GIL is operated under DC voltage for a long time, the surface of the pot insulator will accumul...
