摘要
输电线路转角塔角度如果采用超限水平档距,在转角度数不大于上限的情况下,可以通过转角度数的余度来折算水平档距。具体计算时,采用折减系数的方法,忽略挂线点垂直荷载变化和纵向水平荷载的影响,利用转角塔挂线点水平荷载相等的原则,将输电线路转角塔角度折算成超限水平档距。该方法应用于实际工程中,可达到节约成本的目的。
If transfinite horizontal span is adopted for corner tower angle of transmission line, and turn angle is not larger than upper limit of next angle, horizontal span can be converted to redundancy angle of horizontal span. When doing detailed calculation, specific calculation method by means of reduction factor will be utilized, ignoring influence of hung perpendicular load change and impact of the vertical load level. Using principle of horizontal load equal to comer tower hung point horizontal load equal, angle of comer tower for transmission line can be converted into transfinite horizontal span. If it is applied to engineering practice, cost savings will be realized.
