A Framework Applicable to Outgoing Substation

Abstract

The invention provides a framework applicable to transformer substation outgoing lines. The framework comprises a framework column, a plurality of composite crossarm beams, composite stay ropes and line hanging rings. The framework column is of a single-column lattice steel structure, the composite crossarm beams are arranged on the sides of the framework column respectively, more than two composite crossarm beams arranged on the same side of the framework column are arranged vertically, one end of each composite crossarm beam is fixedly connected with the framework column while the other end of the same is provided with the line hanging ring and connected with the framework column through one composite stay rope in a pulling manner, and all the composite crossarm beams are connected with the corresponding composite stay ropes and the framework column to form a double-umbrella type structure. Since all the composite crossarm beams are connected and combined with the framework columns to form the double-umbrella type structure, compared with an original one in horizontal arrangement, the framework has the advantages that needed horizontal space for guide lines can be saved so as to reduce spacing width between outgoing lines, floor area of a transformer substation is saved, tension and suspension insulator strings are omitted, the framework can be lowered, the space occupied by the original insulator strings is released effectively, and material investment is saved.

Description

technical field [0001] The invention belongs to the field of high-voltage electricity, and relates to a frame suitable for outgoing lines of substations. Background technique [0002] With the continuous development of the scale of power grid construction, there will be more and more substations, and the demand for steel for substation structures will also increase, which not only consumes a large amount of mineral resources, but also causes serious pollution to the ecological environment during the production and processing of steel. . At the same time, the outlet structure of conventional substations adopts a horizontal arrangement of three-phase conductors, and the interval width is relatively large, resulting in a substantial increase in land area. In addition, the tension-resistant and hanging insulator strings are used in the outlet frame of the substation, which increases the investment, and the falling off of the insulator sheet may cause serious damage to the equip...
