Integrated assembling device for direct-current extra-high-voltage ceramic internal insulation supporting piece and connecting part

Abstract

The invention relates to an integrated assembling device for a direct-current extra-high-voltage ceramic internal insulation supporting piece and a connecting part, and belongs to the technical field of porcelain insulators. According to the integrated assembling device for the direct-current extra-high-voltage ceramic internal insulation supporting piece and the connecting part, two supporting stand columns are symmetrically arranged on a base, round holes are formed in the supporting stand columns correspondingly, and rolling bearings are symmetrically embedded in the round holes; the rolling bearings are connected with a fixed frame through rotating shafts; a rotary positioning column is arranged in one side of the fixed frame in a penetrating manner, a pressing plate is arranged at the top of the rotary positioning column, and the pressing plate moves around the rotary positioning column in the horizontal direction and the vertical direction; the cross section of the fixed frame is U-shaped, and pressing blocks are separately arranged at the top of the fixed frame; a supporting plate is arranged in the middle of the fixed frame; a lower supporting plate is arranged at the bottom of the fixed frame; and positioning locking pins are arranged on the supporting stand columns close to one side of the rotary positioning column in a penetrating mode. The integrated assembling device for the direct-current extra-high-voltage ceramic internal insulation supporting piece and the connecting part is simple and easy to operate, the production efficiency of assembly operation is improved, the labor cost and the labor intensity are reduced, and the quality reliability and stability of the assembled product assembly are guaranteed.

Description

technical field [0001] The invention relates to an integrated assembly device for a direct-current UHV ceramic inner insulating support and connecting parts, belonging to the technical field of porcelain insulators. Background technique [0002] At present, my country's UHV DC projects that have been put into operation and are under construction have entered the DC power and are in the leading position in the world in terms of the number of projects, or in terms of transmission capacity, line length and voltage level. However, there is still a big gap in the research and development of core technologies for UHV and UHV DC equipment in my country. Among them, the internal insulation supports used in GIS, GIL, wall bushings and other equipment still rely on imported epoxy materials. Both the performance of the material itself and the procurement link are in a passive situation. Even so, the aging performance of the epoxy material itself and the ablation caused by electrical co...

Problems solved by technology

However, since the weight of the upper part is about 30kg, which is more than 3.5 times the weight of the porcelain part, the weight of the lower part is slightly smaller than that of the porcelain part. It is inconvenient to carry during the process of assembly, curing, moving, cleaning and packaging, and is affected by temperature. Influenced by conditions, manual operation during the hot-fitting process can easily cause burns and other accidents, and the risk of bump damage will increase during the moving and turning process of the adhesive glue, which will affect the bonding and assembly quality of the entire set of components
