Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] Refer to attached figure 1 , this embodiment includes a tower head and a tower body 3. The tower head includes a 500kV tower head I1 and a 220kV tower head II2 located at the upper and lower ends respectively. The tower head I1 has an "I"-shaped structure, and the tower head II2 has an "umbrella" shape Structure, the tower head is equipped with ground wire hanging points, wire hanging points, and jumper wire hanging points. In order to facilitate the distinction, the two sides of the tower head I1 and the tower head II2 are divided into left and right sides.

[0015] The left and right ground wire hanging points 11 and 12 on the left and right sides of the top of the tower head I1 are respectively provided for hanging ground wires, and the middle phase jumper hanging point 151 is also provided on the right side of the top; The left sid...

Abstract

The invention relates to a single-circuit 500kV and double-circuit 220kV mixed-voltage large-span terminal branch tower. The single-circuit 500kV and double-circuit 220kV mixed-voltage large-span terminal branch tower comprises a tower head and a tower body, the tower head comprises a 500kV tower head I and a 220kV tower head II which are located at the upper end and the lower end respectively, the tower head I is of an I-shaped structure, the tower head II is of an umbrella-shaped structure, and the tower head is provided with a ground wire hanging point, a wire hanging point and a jumper wire hanging point. The large-span power transmission line is constructed by utilizing the single-circuit 500kV and double-circuit 220kV mixed-voltage large-span terminal branch tower, the occupied areacan be greatly reduced, the unit corridor conveying capacity is large, land resources are greatly saved, and huge social benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to a high-voltage iron tower, in particular to a single-circuit 500kV and double-circuit 220kV mixed voltage large-span terminal branch tower. Background technique [0002] With the rapid development of social economy, the number of power users is increasing, and the transmission lines are also increasing. The area occupied by the existing transmission line corridors has also increased significantly. However, the limited land area has made the construction of transmission line corridors increasingly tight. In particular, The construction of large spanning corridors of transmission lines spanning large rivers and large river sections is particularly tight, which has become the main constraint factor for the selection of transmission line routes. [0003] The existing frequent 500kV lines and 220kV lines share a large-span transmission line corridor with mixed voltage. Generally, the lines on both sides of the large-span line must b...
