Method and device for determining the supporting force of auxiliary materials for transmission tower legs

Abstract

The invention provides a method and a device for determining power transmission tower leg auxiliary material supporting forces. The method comprises the following steps: an identification step, identifying a V surface in three auxiliary material supporting surfaces of a tower leg from a pre-established power transmission tower leg spatial model; a calculation step, calculating a supporting force increscent coefficient of the V surface; a selection step, selecting supporting points on the V surface; the supporting points being connecting points of a load-carrying material and an auxiliary material of the tower leg; a determination step, according to the calculated supporting force increscent coefficient, selecting the supporting force coefficient and axial pressure of the load-carrying material where the supporting points on the V surface are in, and determining the supporting forces which is to apply on the supporting points of the V surface. The method is simple and convenient in calculation, and calculation accuracy is improved. The method gives consideration on included angles of the V surface and a front surface or a side surface, so that the supporting force of the V surface can reach design standard requirements. The method ensures stability of tower legs, and reduces potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation engineering, in particular to a method and a device for determining the supporting force of auxiliary materials for legs of a power transmission tower. Background technique [0002] With the rapid development of my country's economy, while promoting the continuous improvement of the national economy, my country's power industry is also developing continuously. Transmission lines provide the foundation and guarantee for my country's power supply, and play a key role in the power supply system. Among them, the transmission tower is a structure that supports the conductors and lightning conductors of high-voltage or ultra-high-voltage overhead transmission lines. It is an important part of overhead transmission lines and plays the role of supporting conductors, ground wires and other accessories. [0003] In the design model of the transmission tower, the tower leg is t...
