基站设备断电节能凝露现象的研究

Research on condensation phenomenon during energy-saving shutdown of base station

5G基站多收发通道数、宽带宽、高流量、高发射功率等特性,导致其满载功耗较4G基站大幅增加。5G发展初期,现网基站可能存在长时间无用户的场景,对无用户基站设备进行间隔断电起到节能的效果。间隔断电节能也会带来设备凝露,引起器件、PCB等腐蚀、烧毁,造成基站设备失效。介绍了凝露的基本原理,设计了凝露实验并对基站设备进行对比验证,分析了基站设备产生凝露的原因,最后给出了基站设备避免凝露的使用方案建议。

5G base station has a significant increase in its full-load power consumption compared to 4G base stations due to multiple transceiver channels,wide bandwidth,high traffic and high transmission power.In the early stage of 5G development,since there may be scenarios without users for a long time in the current network base stations,intermittent shutdown of the base stations can play a role in energy saving.However,the intermittent shutdown of the base station saves energy and condensation occurs inside the equipment,which will cause corrosion and burn down of devices and PCB,resulting in the failure of base station equipment.The basic principle of condensation was introduced,the condensation experiment was designed and the comparative verification was carried onto the base station equipment,the causes of condensation on the base station equipment were analyzed,and finally the suggestion for the use scheme of the base station equipment to avoid condensation was given.
