Description

Multifunctional integrated power supply

Technical Field

The application relates to the technical field of power supply of communication base stations, in particular to a multifunctional integrated power supply.

Background

The existing base station power supply is converted from the original simple dependence on a set of switch power supply system into a complex energy source guarantee system consisting of a switch power supply, a power-off sensor, a shunt metering device, an oil engine power generation identification device, a battery sharing manager, an intelligent load manager, intelligent alternating current distribution equipment, 5G distribution equipment and continuously expanded unknown equipment and facilities.

A large number of newly added functional devices in the cabinet will result in: the planning of the internal space of the machine room is disturbed, the space in the cabinet is unreasonably occupied, and the cabinet becomes more congested; after the newly-added equipment is connected with a base station power supply through a bus cable, a large amount of precious direct-current power distribution interface resources of the base station are occupied. The FSU that connects the rotating ring control is dilatation constantly, has crisscross repetition problem when too much new equipment uploads information, and construction cycle overlength and continuous repetition when newly increasing equipment lead to the maintenance point to constantly increase, the constantly increase of construction and maintenance cost.

A connector is arranged between a plurality of functional modules arranged in the cabinet and the bus bar, and the specific structure is shown in fig. 1 (a) - (c). The existing connector consists of two parts of copper sheets, wherein one part is a high-current connecting copper sheet and is responsible for power transmission; the other part is a small current copper sheet which is responsible for signal transmission. The disadvantages of this approach are:

1. according to the design specification requirement of the modular communication equipment, all modules are inserted into the cabinet from the front of the cabinet, the rear of the cabinet cannot be opened generally, and all maintenance operations are performed in the front. Because the copper sheet of this kind of component of heavy current connection socket generates heat seriously, the copper sheet is easy ageing damage, and its life can be less than other components, nevertheless because traditional busbar concentrates on the motherboard of rack rear portion, once there is the component damage on the motherboard, then unable maintenance.

2. Because the energy is input and output from the cabinet panel, and the traditional bus bar is arranged at the rear part of the cabinet, the current flows from the front to the rear of the cabinet, winds a circle and flows back to the front, and a large-current conveying copper bar or a large-current conveying cable is required to be arranged from the bus bar to the panel, so that the cost is increased, and the space is occupied.

3. With the continuous improvement of the power density of the modular device, the input and output currents of a single module are larger and larger, so that the requirement on the capacity of a high-current connector is higher and higher.

The power density of the module is continuously improved along with the technical development of components, but the current capacity of the current connector is only related to the resistivity of materials, and if only copper materials can be used, the current connector cannot be miniaturized, so that the current capacity of the module of the current modular power supply equipment for the communication base station can only supply power to equipment below 75A if the connector is used for connection, and cannot meet the requirement of multi-module power supply under the requirement of 5G communication conditions.

4. After the standardized current connector is applied to a module, in order to solve the problem that a copper foil on a PCB cannot conduct large current, an auxiliary flow guiding copper bar needs to be added on the PCB, so that the structure and the processing technology of equipment are complicated, the associated cost is increased, the energy efficiency is reduced and the like.
