110KV double-loop T connection steel pipe pole

Abstract

The invention proposes a 110KV two-circuit T-joint steel pipe pole. The 110KV two-circuit T-joint steel pipe pole comprises a main pole, a main line cross arm and a T-joint cross arm. The main line cross arm and the T-joint cross arm are mounted on the main pole and the T-joint cross arm and the main line cross arm are arranged in layers on space to form an included angle. When two-circuit lines are switched in from one side of the main line cross arm, the two-circuit lines are switched out from the main line cross arm and the other side opposite to the side. The 110KV two-circuit T-joint steel pipe pole better fulfils the requirements on clearance of a tower body by the wires, optimizes the size of the cross arm, has a clear power transmission line and more rational stress, solves the problems that the floor area is large and the quantity of tower materials and basic materials is large in the traditional T-joint angle bar tray, and effectively saves energy.

Description

technical field [0001] The present invention relates to a steel pipe pole, and in particular to a 110KV double-circuit T-connected steel pipe pole. Background technique [0002] In the construction and transformation of transmission lines, due to economic strength and national conditions, most transmission lines will still be in the form of overhead and will exist for a long time, except for some transmission lines that are replaced by cables. [0003] The traditional 110kVT connection tower generally adopts the conventional double-circuit angle steel tower layout type, and the T connection is completed at the cross-arm head, which can only meet the single-side T-connection or the two-side T-connection in different directions. The traditional four-circuit angle steel tower layout can meet the double-circuit double T-connection, but the cross-arm is arranged in the same plane, and the range of T-connection is limited. The amount of materials and foundation materials is large...

Problems solved by technology

[0003] The traditional 110kVT connection tower generally adopts the conventional double-circuit angle steel tower layout type, and the T connection is completed at the cross-arm head, which can only meet the single-side T-connection or the two-side T-connection in different directions.

The traditional four-circuit angle steel tower layout can meet the double-circuit double T-connection, but the cross-arm is arranged in the same plane, and the range of T-connection is limited. The amount of materials and foundation materials is large, the investment cost is high, and because there are many angle steel tower components, the date of manufacturing and processing of structural components and the date of foundation construction are relatively long

In addition, the traditional four-circuit angle steel tower itself has a large space and volume, and often occupies a large area of ​​land resources when it is put into use. Especially in cities, towns and other areas, it often brings about problems such as building demolition and underground pipelines, pipelines and other facilities. The planning and construction of cities and towns have a great impact, causing a lot of inconvenience to the lives of residents and the work of local planning departments; moreover, the spatial layout of the four-circuit angle steel tower is not clean and beautiful, and it is difficult to maintain during operation
