| 摘 要： | OPGW(Composite Fiber Optic Overhead Ground Wire)又称为光纤架空复合地线，它是利用高压输电线路的一根地线(避雷线)复合组成OPGW来传输光信息。文中阐述了短路电流引起OPGW温升的机理，讨论了OPGW在发生接地故障时的温升和短路电流计算方法，建立了一种完整的计算方法。对OPGW的热稳定性进行了探讨，提出了降低OPGW中的短路电流与热容量的几种措施。

| Abstract: | OPGW(Compossite Fiber Optic Overhead Ground Wire)means using OPGW instead of the lightning wire in the high voltage transmit electricity circuitry to transmit information The paper introduces elements of short circuit current result in the temperature rise of OPGW Then,it discusses the calculation approach of temperature rise and short circuit current when the grounding fault takes place and establishs an integrated calculation approach It also proges into analysis of OPGW transient stability and bring forward several measures to reduce short circuit current and thermal capacity on OPGW |
