摘要
通过建立架空输电线路导线覆冰厚度的力学模型,推导出了导线覆冰厚度及导线弧垂计算公式。利用该公式计算±800 k V复奉线湖南区域导线覆冰厚度,与现场测试结果相比,计算误差为9.02%,可为提前预测导线覆冰厚度提供参考,还可为导线覆冰防护提供预警。
Through establishing icing thickness mechanical models for overhead transmission lines,the formula for calculatingthe ice thickness of lines and wire sag is derived. Using the formula,thickness of the ice coating of ± 800 kV Fufeng line in Hunan region was calculated. Comparing the calculating results with field test results,the calculation error was 9. 02%. The model can be used to predict the thickness of wire ice coating in advance,and provides a preliminary warning for icing protection.
