220kV双回输电线路钢管杆设计档距及安全系数取值分析

Analysis on 220kV Double Circuit Transmission Line Steel Tube Pole Span and Safety Factor Value

介绍架空输电线路钢管杆水平档距和安全系数的取值原则,对河北省南部电网某220kV双回架空输电线路钢管杆不同安全系数和设计档距组合计算结果进行对比分析,认为水平档距250m、导线安全系数为6时工程最经济,并提出设计档距及安全系数的建议。

This paper introduces the circuit transmission line steel tube pole span and safety factor value principle,according to comparison analysis on composition calculation result of the different safety factor and design pole span steel pipe of southern Hebei province power grid 220kV double circuit transmission line rod,considers that the project is the most economic when the horizontal span is from 250m,wire safety coefficient is 6,puts forward the design span and safety factor coefficient suggestions.
