With the rapid development of 5G base stations, the problem of energy consumption of base stations has become more and more prominent. An efficient and reliable base station power distribution system solution is an important guarantee for improving the energy consumption efficiency of base stations and realizing energy saving and consumption reduction of base stations. The electrical load situation of each distribution circuit is the premise of this scheme. In addition, in terms of base stations, whether it is a macro base station with greatly increased equipment power or a large number of small and micro base stations, a low-voltage power distribution system is required for power supply.

Recently, in order to reduce the operating cost of digital infrastructure, various localities have issued relevant policies for "replacement to direct power supply", that is, to establish a green channel for the review and installation of telegrams for communication base stations, and to support qualified 5G base stations to convert power supply to direct power supply and participate in direct power transactions. . Because the power supply method when the early base station was established was to transfer power supply, that is, power supply to the base station through the community power supply equipment (customer property equipment), and the base station electricity fee was charged by the property. increase in cost. Therefore, the transformation of "turning and straightening" is urgent.

For the transformation of the base station, we can roughly divide it into two aspects based on its power supply mode: AC and DC. Its retrofit solution will also be introduced in two parts.

The following is a topology diagram of common base station energy consumption and power distribution:

For monitoring point A, it can be divided into AC single-circuit monitoring and AC multi-circuit monitoring, corresponding to the following scenarios 1 and 2 respectively.

For monitoring point B, it can be divided into DC multi-circuit monitoring, corresponding to the following 3 kinds of scenes.

1. Application Scene 1: One-way AC three-phase or three-way single-phase metering

Application Scene 2: One-way AC three-phase or three-way single-phase metering

Application Scene 3: One-way AC three-phase or three-way single-phase metering
