Universally adaptive multi-module parallel operation capacity expansion power supply system

Abstract

The invention discloses a universally adaptive multi-module parallel operation capacity expansion power supply system, which comprises at least one capacity expansion branch which is connected in parallel with an original rectification branch and is converged into a direct current bus, a rectifier and an intelligent adapter are connected in series on the capacity expansion branch, and the input end of the capacity expansion branch is connected with the output end of an alternating current input power distribution unit. The manufacturers and models of all rectifiers in the capacity expansion branch and the original rectification branch are not completely the same or completely different. The manufacturers and models of the rectifiers on the capacity expansion branches are not completely the same as those of the rectifiers on the original rectification branches, so that the resource integration of the rectifiers of different manufacturers and models is realized, the work matching with the original rectification branches and the current sharing management among the interiors of the plurality of capacity expansion branches are realized through the intelligent adapters. The power supply stability, the high efficiency and the reliability of the system are improved, the power supply capacity expansion can be realized without changing the original power supply system, the value maintaining and value increasing of national assets and the service life prolonging of the assets are realized, and the method is an important means for reducing cost and increasing efficiency of communication operation enterprises.

Description

technical field [0001] The invention relates to a base station power supply system, in particular to a universally adaptable multi-module parallel expansion power supply system. Background technique [0002] Since the 1990s, all kinds of public communication networks in my country have experienced rapid development for nearly 30 years. The depreciation of the assets of the original switching power supply system by various operators and tower companies has reached the end of life, and the functional structure of the original switching power supply system does not meet the new requirements. Network operation requirements, the original switching power supply system does not meet the capacity requirements after load expansion, the original switching power supply equipment manufacturers cannot provide continuous after-sales maintenance and other technical support, etc., there are a large number of old switching power supplies that are idle and waiting to be scrapped. System; Althou...

[0002] Since the 1990s, all kinds of public communication networks in my country have experienced rapid development for nearly 30 years. The depreciation of the assets of the original switching power supply system by various operators and tower companies has reached the end of life, and the functional structure of the original switching power supply system does not meet the new requirements. Network operation requirements, the original switching power supply system does not meet the capacity requirements after load expansion, the original switching power supply equipment manufacturers cannot provide continuous after-sales maintenance and other technical support, etc., there are a large number of old switching power supplies that are idle and waiting to be scrapped. system; although there are various reasons for the scrapping of these idle assets withdrawn from the warehouse, most of the switching rectifiers are still in a usable state, and the existing conventional technical solutions cannot achieve effective integration and reuse of these devices

[0003] At the same time, in the process of increasing the load capacity of the base station, the old switching power supply system of some sites cannot buy the corresponding rectifier module due to the manufacturer's suspension of production, bankruptcy or production and operation shift, resulting in insufficient configuration of the rectifier module or forced replacement of the power supply , resulting in idle assets, unnecessary increase in investment costs
