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±800kV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。

Abstract:

Through establishing icing thickness mechanical models for overhead transmission lines, the formula for calculating the ice thickness of lines and wire sag is derived. Using the formula, thickness of the ice coating of ±800kV 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.
