Abstract

Disclosed in the invention is a novel GIS main bus, comprising a metal can using SF6 gas as an insulating medium, an A phase capacitive type insulated bus, a B phase capacitive type insulated bus, and a C phase capacitive type insulated bus. The A phase capacitive type insulated bus, the B phase capacitive type insulated bus, and the C phase capacitive type insulated bus are connected with interval butted parts of the GIS through the metal can using SF6 gas as an insulating medium. According to the invention, the provided novel GIS main bus has the following beneficial effects: connection of intervals of all loops of the GIS is realized based on the metal can using SF6 gas as an insulating medium as well as the A phase capacitive type insulated bus, the B phase capacitive type insulated bus, and the C phase capacitive type insulated bus that are connected with the metal can; there is no high voltage exposure point; the structure of the main bus is compact; cost is low; the amount of the SF6gas is substantially reduced; and the work load for installation and debugging and maintenance is low.

Description

technical field [0001] The present invention relates to the main bus bar of combined electrical appliances used in power system. Background technique [0002] In the power system, the main bus bar of the combined electrical appliance GIS adopts SF 6 Gas insulation, which occupies less land, has no high-voltage exposure points, and has a compact structure. [0003] However, the main busbar of combined electrical equipment GIS adopts SF 6 Gas insulation is expensive, SF 6 The gas consumption is large, and the installation, commissioning and maintenance workload is heavy. Contents of the invention [0004] The purpose of the present invention is to provide a non-high pressure exposure point, compact structure, low cost, SF 6 The main busbar of new combined electrical appliances with a large reduction in gas consumption, less installation, commissioning and maintenance workload. [0005] In order to achieve the above goals, the present invention provides a new main busbar...
