摘要
文中介绍了通信基站的电源系统,包括交流供电系统、直流供电系统和接地系统,论述了等电位在基站建设中的重要性。根据基站机房内外设备的防雷特点,对电源系统的雷电分级防护措施和SPD的选择进行了论述。
In the paper, an electrical power system of base station is introduced in detail, including AG power supply system, DC power supply system and earthing system. The importance of equipotential in base station construction is discussed. According to the lightning protection characteristics of telecommunication equipment, both indoor and outdoor base station, the graded lightning protection measures of the electrical power system and the selection of SPD are analyzed.
