The Stress Analysis and Calculation Method of the Poles of Different Arrangement Styles in the Distribution Network Lines and the Research of 'Abandoning Wires to Protect Electric Poles' Project

摘要

The force situation of pole was analyzed in detail through the establishment of three-pole model, and the five-pole model was built on the basis of the former model. Besides, the influence of external factors including height difference, span, wind angle and line angle to the pole were studied, and the method to improve the force situation of pole: changing the pole arrangement styles was concluded in the research. At the end of the paper, the important points of "abandoning lines to protect electric poles" project were explained and illustrated by an example of implementation. It offered theoretical support to the implementation of "abandoning wires to protect poles" project.
