Abstract

Modern telecommunications deployment increasingly involves the use of remote sites. Equipment is housed in enclosures that range in size and scope from large concrete buildings containing entire switches to small cabinets containing a few lines of transmission equipment. In most cases, reserve energy during AC power failures is supplied from lead acid batteries collocated with the electronics within the enclosure. The fact that all lead acid batteries generate hydrogen continuously during their operation is an important design parameter for both the enclosure, and the equipment which the batteries are designed to support. While much published material has dealt with VRLA battery operational issues such as hydrogen evolution and thermal runaway from a design and engineering viewpoint, this investigation has attempted to represent a users perspective. In determining the capabilities and limitations of both the batteries and their end users the paper attempts to present some real world principles to aid successful applications. While predominantly focussing on wireless, such principles could also apply to other outside plant type applications.<>

远程通信站点的环境问题:蜂窝装置中VRLA电池的氢演变

现代电信部署越来越多地涉及到远程站点的使用。设备安装在各种尺寸和范围的外壳中，从包含整个开关的大型混凝土建筑物到包含几条传输设备线路的小型机柜。在大多数情况下，交流电源故障期间的备用能量由与外壳内电子设备配置的铅酸电池提供。所有铅酸电池在运行过程中都能连续产生氢气，这是外壳和电池设计支持的设备的重要设计参数。虽然许多已发表的材料都是从设计和工程的角度来处理VRLA电池的运行问题，如氢气的释放和热失控，但本研究试图从用户的角度来考虑。在确定电池及其最终用户的能力和限制时，本文试图提出一些现实世界的原则，以帮助成功的应用。虽然主要集中在无线，这些原则也可以适用于其他外部工厂类型的应用。
