Abstract

The invention relates to a charge self-adapted dissipation basin-type insulator and belongs to the technical field of power transmission and distribution devices. The insulator is an integral formed structure with a U-shaped cross section and comprises a central insert and insulation zones symmetrically arranged on two sides of the central insert, wherein the insulation zones are composed of insulation subzones, self-adapting subzones and edge flanges, and the central insert and the insulation subzones, the self-adapting subzones and the edge flanges respectively form the bottom, side wall and top of the U-shaped structure, the insulation subzones are prepared by mixing epoxy resin, aluminum oxide and a curing agent, the self-adapting subzones are prepared by mixing epoxy resin, aluminum oxide doped with a nonlinear material and a curing agent, and the edge flanges are made from the same material adopted by the self-adapting subzones or are metal flanges. The insulator can adjust surface charge accumulation itself in the operating process in a self-adapted mode, limit the surface charge quantity in a safety range and accordingly ensures safe and stable operation of a device.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution equipment, in particular to a basin-type insulator for self-adaptive dissipation of charges. Background technique [0002] Gas-insulated metal-enclosed transmission line (GIL) has many characteristics such as large transmission capacity, low loss, high safety and environmental friendliness. It is an effective means for large-capacity and long-distance power transmission. In special environments such as dense transmission corridors, dangerous landforms, rivers, lakes and seas, gas-insulated metal-enclosed lines become the best choice for power transmission. At present, although gas-insulated metal-enclosed transmission lines have gradually been widely used in the world, however, they are mainly used in AC power grids, and the application of GIL in DC transmission systems is rarely reported. In recent years, many manufacturing units in the world, such as Japan's Mitsubis...
