| 摘 要： | 通过分析角度负荷与张力及转角度数的关系，建立了一个量化关系式：PJ=2TxSin（0／2），经计算分析得出，重覆冰区架空输电线路耐张转角塔转角度数在30°时，既安全又经济的结论，回答了《重覆冰架空输电线路设计技术规定》（DIL/T5440—2009）“转角度数不宜过大”的问题，为以后的重冰区输电线路路径选择提供了理论依据。

| Abstract: | In this paper, through the analysis of corner degree, tension and corner degree, a quantitative relationship is established： PJ = 2TxSin （ θ/2）, through the calculation and analysis, when the corner value of strain - resistant comer tower for overhead transmission line is in 30 ° in heavy ice area, the strain - resistant corner towel is safe and economic, this result replies to the question of corner degree should not be too big in ＂ Design technical requirements of overhead transmission line covered by heavy ice ＂ （ DL/ T5440 - 2009 ）, and provides theory basis for choosing line path of overhead transmission line in heavy ice area. |
