OPPC在220kV线路的应用与分裂导线的粘连问题

The application of OPPC in line with 220kV and the problem of the adhesion of bundled conductors

光纤复合相线(Optical Phase Conductor,OPPC),是在传统的相线结构中嵌入光纤单元的一种新型特种光缆。用OPPC代替三相中的一相,解决电网通信问题,OPPC在220kV及以上线路中应用时,可以通过多种方式避免分裂导线互相粘连的问题。文章通过分析分裂导线粘连的原因并对比各种解决方法的优劣,给出工程应用当中的建议,对指导日后工程具有积极的贡献。

Optical phase conductor （OPPC）is a new type of special fiber cable with fiber units embedded in traditional phase line structure.Using OPPC to solve the communication problems of network instead of one phase of the three phases.OPPC can avoid the problem of mutual adhesion of bundled conductors through many ways when it is used in the line with 220kV or above.Through analysis the cause of the adhesion of bundled conductors and compare the advantages and disadvantages of various solutions,this paper proposes some suggestions in project,which has positive contribution for quality future project.
