Problems solved by technology

Although the single-pole tower has a simple structure, a small footprint, and is easy to install and set up, it is mainly used for occasions of temporary or rural power consumption due to insufficient bearing pressure capacity, and can only be mounted on a small-capacity distribution station area of ​​80-150kVA , it is difficult to meet the increasing load demand
In addition, the transformer is installed on the side of the pole in the single-pole distribution station area, which makes the force on the single-pole tower uneven. In some areas, the pole has fallen down.

Embodiment Construction

[0015] In order to better understand the technical solution of the present invention, it will be described in detail below through specific embodiments in conjunction with the accompanying drawings:

[0016] see figure 1 , a composite tower for a single-pole distribution station area of ​​the present invention, including a tower 1, a distribution transformer 2 and a low-voltage cabinet 3.

[0017] see figure 2 , the pole tower 1 is a multi-layer hollow circular pipe structure, and the pipe wall of the multi-layer hollow circular pipe structure is a three-layer composite structure, which is a steel pipe layer 11, a concrete layer 12 and a GFRP layer 13 from the inside to the outside. The innermost layer is a steel pipe layer 11, which has good tensile properties, can reduce the deformation of the rod body when subjected to bias, and constrains the shape of the internal cavity. The cavity contains transmission lines, so that the transmission can be arranged inside the tower 1....

Abstract

The invention discloses a composite pole tower for a single-pole power distribution area. A pole tower with a three-layer composite structure of a glass fiber composite material (glass fiber reinforced polymer), concrete and a steel pipe is adopted, and strength of the pole tower is guaranteed. A power distribution transformer is arranged at the top of the pole tower so that the overall center ofthe pole tower structure is kept stable. Single-edge holes are formed in the pole tower so that external circuits of a low-pressure cabinet and the power distribution transformer are distributed inside the pole body of the pole tower, the external circuits are prevented from being exposed outside, the circuits are prevented from being corroded for environmental reasons, and meanwhile, it can alsobe avoided that an influence is caused to stability of the pole tower because the circuits are pulled by external force.

Description

technical field [0001] The invention relates to a composite pole tower used in the field of electric power engineering for a single pole distribution station area. Background technique [0002] At present, in terms of installation and mounting in the domestic distribution station area, most of the towers are iron towers and cement towers, and the main ones are twin towers. Although the single-pole tower has a simple structure, a small footprint, and is easy to install and set up, it is mainly used for occasions of temporary or rural power consumption due to insufficient bearing pressure capacity, and it can only be mounted on a small-capacity distribution station area of ​​80-150kVA , it is difficult to meet the increasing load demand. In addition, the single-pole distribution station area adopts the form that the transformer is installed on the side of the pole, which causes uneven force on the single-pole tower. In some areas, the pole has fallen down. The development of...
