Problems solved by technology

This method is equivalent to directly cutting off the circuit between the battery and the busbar. Since the current on this circuit is very large, this method of pulling out the fuse is likely to cause spark discharge at the contact end of the fuse, which is dangerous to the operator.

Embodiment Construction

[0022] The primary power supply system of an outdoor communication base station usually includes the following modules: rectifier module, monitoring module, DC power distribution module and backup power module. The rectifier module converts the AC power input by the power supply into DC and outputs it as the busbar voltage of the load and backup power module; the monitoring module receives the remote control commands of the software and sends control signals through the signal line to monitor and manage the entire power system. The above control signal controls the on-off of each branch in the power system; the DC power distribution module divides the DC voltage of the busbar into multiple branches and distributes them to the load according to the current requirements of each branch, and provides the connection of multiple batteries; When the power module is working normally, it receives the busbar voltage through the DC power distribution module to store electricity for it.

Abstract

The system includes following modules: monitoring module in use for sending control signal in use for controlling on / off signals of all branches in power source system; rectification module in use for converting AC from power source to DC, which is output from bus; module of stand-by power supply in use for supplying power for load when AC is breaken; DC distribution module in use for dividing DC voltage into multiple voltages to provide the voltages to loads, and connecting to the module of stand-by power supply; being connected to monitoring module and DC distribution module, the control device is in use for controlling on / off of branches of module of stand-by power supply. Through turning on / off control signal for branches of module of stand-by power supply, the control device controls on / off between module of stand-by power supply and bus. Moreover, control signal of branch current is only tens to hundred mA so as to reach effect of safe operation.

Description

technical field [0001] The invention relates to a power supply system of a communication system, in particular to a primary power supply system of an outdoor macro base station. Background technique [0002] Power supplies are an important part of communication systems. In the composition of the communication network, the power supply is a necessary condition to ensure smooth communication. It applies not only to power system communications, but also to all private network communications and public network communications. [0003] In the current prior art, the primary power supply system of an outdoor communication base station usually includes the following parts: a rectification module, a monitoring module, a DC power distribution module and a backup power module. figure 1 It is a block diagram of a power supply system. The rectification part converts AC power into DC power; the monitoring part monitors and manages the entire power system through software; the DC power ...
