摘要
为了实现内蒙古锡林浩特地区建设的汗海—塔拉500 kV输电线路的长距离光传输,从经济性和安全可靠性方面对建设光通信中继站和采用光纤放大器+遥泵技术两种方案进行了技术比较分析,证明建设地下中继站具有可行性。并介绍了光通信地下中继站的设计原则、建筑土建、防水通风、通信设备供电及接地方案等,该方案应用后,实现了在冬季高寒、供电网络薄弱地区光通信电路的可靠中继,达到了节能降耗的目的,具有推广应用价值。
For carrying out HanHai-Tara 500 kV OPGW transmission line in XiLinHaoTe, we compared the optical communications relay station with the fiber-optic amplifier ＋ faraway pump technique from economy and reliability, and proved that the underground relay station scheme was viable. In this paper we introduced the design principle, construct project, watertightness and well ventilated, power supply for correspondence equipments and connect ground case etc. of the underground optical communications relay station. This scheme realized reliable optical communication circuit relay in cold winter, power supply network unreliable regions, and lowered energy depletion, did have expansion applied value.
