Description

Intelligent alternating current distribution device for base station power supply

Technical Field

The utility model relates to the technical field of communication power supplies, in particular to an intelligent alternating-current power distribution device for a base station power supply.

Background

The base station communication power supply system is an important component of the communication system, and is often called the "heart" of the communication system, and plays an extremely important role in the communication system. If the communication power supply system fails, the power supply quality is reduced or the power supply is interrupted, and the communication system cannot operate normally, which inevitably causes the failure of the communication system. Failure of the communication system would cause significant economic loss and immeasurable political impact.

With the steady advance of 5G infrastructure construction, the power of 5G equipment is greatly improved, the demand of a base station on electric energy is further increased, and correspondingly, higher requirements are provided for the reliability of base station alternating current power supply, the power and efficiency of a power supply system, the capacity and reliability of base station power reserve and power generation and the like.

The 5G base stations are more densely distributed, which requires fully utilizing the existing base stations to perform capacity expansion and building more micro (small) type 5G base stations. The space of the power supply cabinet of the electric energy required for 5G communication in the existing base station is extremely limited, and under the condition that the output power of the 5G communication power supply system needs to be greatly increased, the communication power supply system is required to keep the volume basically unchanged or even smaller, namely, the power density is further improved. Therefore, no matter the existing base station is expanded and upgraded to a 5G base station, or a new micro (small) type 5G base station is required, the communication power supply system is required to achieve integration, intellectualization, modularization and miniaturization of the system as far as possible while achieving higher power output, higher efficiency and higher reliability. The power of the 5G communication equipment is greatly increased, and the requirement that the input power of the commercial power and the power generated by the oil engine need to be synchronously increased can be met.

In addition, the co-building and sharing of the base stations are important measures for effectively reducing the consumption of communication facilities on land and power resources, and can save funds to a certain extent and realize energy conservation and emission reduction. Multiple operators in the co-established shared base station share the same communication power supply system, so that the power supply capacity of the communication power supply system needs to be improved, and further higher requirements on the capacity and reliability of alternating current power distribution of the base station are provided. Because the operator quantity is few in the traditional basic station, 3G/4G load power is less relatively, uses single-phase oil engine just can satisfy the power generation demand, along with the overall arrangement of sharing basic station under the 5G load, will face the sight that many oil engines were generated electricity simultaneously, and the management and control to the efficiency of power generation management, cost will be stricter. In addition, multiple operators share the base station, different operators have different requirements on power generation service, and operators who do not purchase power generation service should implement differentiated management. Because the power supply function of the traditional base station can not meet the requirements of the characteristics, Chinese iron towers are added with a plurality of peripheral equipment on a power supply system of the traditional base station in practical application to solve the problem of the functional defects of the power supply of the traditional base station, the commercial power and the oil engine need to be manually switched for power generation during the power generation, and the commercial power can not be recovered simultaneously when one person deals with multi-site power generation, so that the power generation operation, maintenance and management are very difficult, the power generation efficiency is low, the power generation cost is high, and the operation cost of the base station is greatly increased.
