摘　　要： 提出了分析计算光纤复合架空地线(OpticalFiberCompositeOverheadGroundWires,OPGW)热性能的改进综合法,它利用分布函数求解趋肤效应并采用数值计算方法求解初始状态,在短路电流冲击的全过程中求解热交换性能,具有精度高、效果好等特点。利用该方法详细分析了几种常用OPGW的结构、材料与热性能之间的关系,结果表明光缆热性能分析对于OPGW产品的选型及运行维护具有重要的指导意义。 An improved integration algorithm to analyze heat properties of optical fiber composite overhead ground wires （OPGW） is proposed. This method can solve skin effect by distribution function and initial state by numerical calculation, and can also solve the heat exchange performance during short circuit current surge. Experiment results show the proposed method is accurate and effective. Applying the proposed method to several OPGW cables being often used, the relation among their structure, material and heat properties is analyzed in detail. Analysis results show that the heat property analysis is significant in choosing the type of OPGW products and their operation and maintenance.
