| 摘 要： | 为对输电线路的覆冰情况进行监测和计算,笔者提出了通过对耐张段及直线塔张力的测量来对输电线路稳态覆冰状况进行监测的方法,根据耐张段张力倾角和悬垂绝缘子串张力偏斜角进行输电线路覆冰实时计算模型的建立,并进行了试验验证。结果表明,该方法计算得出的覆冰值精度较高,可应用于多档输电线路覆冰的监测计算。

| Abstract: | To calculate and monitor ice-coating on transmission lines,a new on-line monitoring method of ice-coating on transmission lines was proposed according to the tensions on tangent tower and tension section.A model was put forward for real-time calculation of the ice-coating thickness through the axial tension,the tension inclination angle of tension section,and the tension excursion angle of suspension insulator-string.Experiment was conducted to verify the method.The result shows that the proposed method performs well in ice-coating thickness calculation,which infers the method can be used to on-line monitor and calculate ice-coating thickness on transmission line. |
