光端子在承德110kV汤道河智能站的应用研究

Application of Optical Fiber Terminal Block in the 110 kV Tangdaohe Chengde Intelligent Substation

随着数字化技术的推广,智能变电站中二次设备保护屏柜内的大量二次电缆回路被光纤回路所取代,原有的二次电缆回路设计标准及其规范已不再适用,而新的柜内光纤回路标准及规范还未完善。借鉴成熟规范的二次电缆回路设计思路,结合工程对智能变电站光纤回路的要求,在河北承德110 kV汤道河智能站中首次完整地应用新设备——"光端子",并以此为基础引发对柜内整个光纤回路的探索和改进。通过新方案的引用,该工程的柜内二次光纤回路设计更有利于工程设计标准化和工程实施、维护的合理化。

With the development of digital technology, massive secondary cable circuits in the secondary equipment protective panel are replaced by fiber circuits in the intelligent substation. The original design standards and norms of secondary cable circuit is no longer applied in this field, while the new standards and norms of fiber circuit are still inadequate. This paper draws on the mature design of secondary cable circuit for reference, combining with the demand for cable circuit of intelligent substation in the project. For the first time, the new equipment, Optical fiber terminal block is completely applied in the 110 kV Tangdaohe intelligent substation in Chengde, Hebei province. Based on this, the whole fiber circuit in the panel is to be explored and improved. Moreover, the application of this project makes the design for secondary fiber circuit more beneficial to design standardization, implementation and maintenance of the project.
