摘　　要：以500kV输电工程中带有绝缘子的电力架空线为研究对象,简化绝缘子的力学模型,结合悬链线方程推导了带有绝缘子的架空线垂度、张力等计算公式。运用本文方法分析、计算典型实例,并将计算结果分别与实测值和国家电网公司典型设计值比较,表明本文算法的正确性,为考虑绝缘子影响的电力架空线力学分析提供有效的方法。The overhead power line with insulator is studied.The formulation considering the sag and tensile force of the overhead power line is deduced based on the simplified mechanical model of insulator.The catenary cable method is taken into account.The calculating results of the classical design and this method are compared,which proves the correctness of the suggested arithmetic.It provides an effective method to analyze the overhead power line under the influence of insulators.
