The application of multi-loop instruments in the "straightening" of base stations

Introduction With the rapid development of 5G base stations, the energy consumption problem of base stations is becoming more and more prominent, efficient and reliable base station power distribution system solutions, is to improve the energy consumption efficiency of base stations, to achieve energy saving and consumption reduction of base stations is an important guarantee, through the multi-loop instrument to monitor the electrical load of each distribution circuit is the premise
of the program.
In addition, in terms of base stations, whether it is a macro base station with a significant increase in equipment power, or a large number of small and micro base stations, a low-voltage distribution system is required for power supply
.
1.
Industry policies Recently, in order to reduce the operating costs of digital infrastructure, various localities have issued relevant policies for "conversion and reform", that is, the establishment of a green channel for telegraph review and installation of communication base stations, and support the conversion of qualified 5G base stations to direct power supply and participation in direct power transactions
.
Because the power supply method used in the early establishment of the base station was to transfer power supply, that is, the base station power supply was carried out through the residential power supply equipment (customer property rights equipment), and the property charged the base station electricity fee, which not only had a hidden danger of electricity use, but also caused an increase
in electricity costs.
Therefore, the transformation of "turning straight" cannot be delayed
.

Product introduction For the transformation of the base station in terms of "conversion to straight", we can roughly divide it into 2 aspects based on its power supply mode: AC and DC
.
Its retrofit solution will also be presented
in two parts.
The following is the topology map of common base station energy consumption and distribution: For the monitoring point A, the situation can be divided into AC single-loop monitoring and AC multi-loop monitoring, corresponding to the following scenarios 1 and 2
respectively.
The case of monitoring point B can be divided into DC multi-loop monitoring, corresponding to the following scenario 3
.
1, the application scenario one: one way AC three-phase or three-way single-phase metering product picture: configuration scheme: 2, application scenario two: multi-channel AC three-phase and single-phase metering guide rail product picture: configuration scheme: application example - a base station on-site use examples are as follows: embedded product pictures: configuration scheme: 3, application scenario three: DC multi-loop monitoring -48V electrical diagram product picture: configuration scheme: application example - a base station on-site use examples are as follows: 3, conclusion By installing AC/DC intelligent monitoring equipment on 5G macro base stations and sub-stations such as small base stations, we can maximize the support for qualified base stations from power supply to direct power supply, which not only eliminates safety hazards for base stations, but also improves the reliability of electricity consumption, and effectively reduces the operating electricity costs
of mobile, Unicom and tower companies.
