分布式基站的电击保护 |
ITU-T K.97建议书探讨分布式基站(DBS)的站塔雷电保护。DBS是一种新型无线电基站,由一个位于站塔的远程无线电单元(RRU)和一个位于塔底机房的基带单元(BBU)构成。ITU-T K.56建议书对DBS雷电保护的阐述并不完整。 本建议书的主要目标是RRU雷电保护,以及与直流电(DC)电缆的整流器接口和DBS的连接。 对这些接口的保护是通过安装保护模块。此外此建议书还描述了可能对这些装置采取的保护方案。 本建议书指出何时应使用这些保护模块及其可接受的电流强度。此外,还指出了馈电线所需的电涌保护装置(SPD)。 本建议书还展示了保护模块和光缆的连接配置。 附录I展示了隔离保护方案的一个示例。 |
