220kV线路保护光纤化改造的实践与应用

Practice and Application of Fiber Renovation of 220 kV Line Protection

为提高220 kV线路保护通迅的安全可靠性,对重钢220 kV长钢东、长钢西线路保护通讯方式进行全面光纤化升级改造,制定了改造方案,介绍了改造过程,通过项目的实施,实现了高压线路保护通道光纤化升级改造在重钢的实际应用。

In order to improve the safety and reliability of the 220 kV line protected communication,a comprehensive optical fiber upgrading renovation program of Chongqing Steel's 220 kV line protected communication mode was drawn up and carried out.The transformation process was introduced.Through implementation of the project,fiber-optical upgrading of the high-voltage line protection channel was practically realized in Chongqing Steel.
