Overview
With the rapid development of China's communication industry, the number of 4G base stations has exceeded one million. The 5G standard has been released. Major operators and tower groups are also laying out new generation communication base stations. The power consumption of base stations is increasing, and the intelligent monitoring and fine management of communication base stations have become the research direction of operators and enterprises.
The sharing of base stations by operators can reduce social capital investment, but the problem of energy consumption measurement has plagued major operators. Through the exchange of intelligent electricity meters, the sub metering of power consumption in the base station and the branching metering equipment in the base station can achieve energy consumption management and operation status monitoring of CMCC, China Unicom, China Telecom and other operators in the base station. Through FSU, the data can be uploaded to the monitoring platform to provide reliable guarantee services for later operations. The separate metering equipment of the base station complies with the Technical Requirements of QZTT 2205-2017 DC Electricity Metering Module, and the AC smart meter complies with the Technical Specifications of QZTT 1017-2015 Base Station AC Smart Meter.

Distribution Composition of Base Station
The power supply system of the base station is mainly composed of AC power supply system and DC power supply system. AC power supply system consists of one mains power supply, one generator power supply, surge protector and AC distribution box (with the function of mains and generator conversion). DC power supply system consists of high-frequency switch combined power supply (including AC power distribution unit, monitoring module, rectifier module, DC power distribution unit) and two groups (or one group) of batteries.
The switching power supply, air conditioning, lighting and sockets in the base station are powered by the AC distribution box, and high-precision circuit measurement is achieved through the multi loop AC meter. The various communication equipment in the base station is mainly powered by the DC system, and the DC power circuit metering equipment is used to monitor the energy consumption of communication equipment of different operators. Finally, they are connected to the operation and maintenance monitoring platform through FSU equipment, realize effective monitoring and operation management of communication base station energy consumption.
Our recommended products for base station separate metering equipment are as follows:
Configuration Scheme
AC Metering Circuit Distribution Scheme
The metering circuit distribution scheme is as follows: one three-phase metering circuit is used for mains power input circuit, generator input circuit and switching power supply circuit respectively, and one circuit is reserved (which can be used for air conditioners or other equipment).
DC Metering Circuit Distribution Scheme
The metering separate distribution scheme is as follows: the total metering circuit, the CMCC equipment circuit, the China Telecom equipment circuit, and the China Unicom equipment circuit are measured by one channel respectively, and two channels are reserved.
