Overhead method and system of power transmission line

Abstract

The invention discloses an overhead method and system for a power transmission line, the power transmission line is arranged on a concave terrain, the peak-valley difference of the concave terrain meets a set peak-valley threshold, and the overhead method comprises the following steps: setting one or more cables based on the length of a concave terrain road section; the two ends of the cable are fixed to the two sides of the concave terrain. And hanging the power transmission line on the cable. According to the technical scheme, the power transmission line is overhead on a road section where power transmission line channel resources are short, the power transmission line corridor selection range can be expanded, harmony and unification of the power transmission line and the natural environment can be achieved in a natural scenic area, and the construction cost of the power transmission line is reduced.

Description

technical field [0001] The invention relates to the field of power transmission lines, in particular to an overhead method and system for power transmission lines. Background technique [0002] Electricity has been integrated into people's lives, and power transmission has gradually expanded from densely populated plain areas to sparsely populated mountainous areas. Compared with mountainous areas, the transmission lines in the plains are scarce. Especially in the mountainous areas, the operating lines occupy the corridors with better conditions. The congenital conditions of the newly-built lines are even worse, causing various strategic passages to be crowded in the same narrow line corridor. Force majeure such as frequent natural disasters and large-scale wildfires may cause multiple circuits to trip at the same time. At the same time, with the in-depth advancement of the hydropower transmission project, the newly put into operation line project has increasingly penetrated...

AI Technical Summary

Problems solved by technology

Overhead lines mainly refer to overhead open lines, which are erected on the ground. It is convenient to erect and maintain, and the cost is low, but it is easily affected by weather and environment (such as strong wind, lightning strikes, pollution, ice and snow, etc.) and cause failures. At the same time, the entire transmission corridor Occupying a large area of ​​land, it is easy to cause electromagnetic interference to the surrounding environment

At present, some work has been done on the use of line corridors in combination with terrain conditions. For example, F-shaped towers are used on slopes, which can effectively increase the distance between the conductors and the ground and reduce the height of the tower, but there must be a suitable tower position.
