| 摘 要： | 为降低高压交流线路因电磁感应导致的地线损耗,提出了光纤复合架空地线(optical fiber composite overhead ground wire,OPGW)换位和普通地线分段绝缘的地线连接方式,并与常用地线运行方式的地线损耗进行了定量比较,计算结果表明:该地线连接方式的地线损耗仅为常用运行方式的25%,节能效果明显,同时OPGW电气上保持连续,其通信功能不受影响。

| Abstract: | To reduce the ground wire loss caused by inductive coupling in high voltage AC transmission lines,a new ground wire connection mode,in which the transposition of the optical fiber composite overhead ground wire(OPGW) is combined with sectionalized insulation of common ground wire,is proposed and quantitatively compared with the loss of ground wire adopting commonly used operation mode.Calculation result shows that the loss of ground wire adopting above-mentioned operation mode is only 25% of commonly used g... |
