Direct current power supply system for communication

Abstract

The invention discloses a direct current power supply system for communication, and relates to the technical field of power supply equipment. The direct current power supply system comprises a 220V mains supply, an electric control change-over switch, a backup power supply, a rectifier circuit, a direct current power distribution apparatus, a real-time acquisition apparatus, communication equipment and a monitoring apparatus, wherein the 220V mains supply is connected with the electric control change-over switch; the electric control change-over switch is connected with the backup power supply and the rectifier circuit separately; the rectifier circuit is connected with the direct current power distribution apparatus; the direct current power distribution apparatus is connected with the real-time acquisition apparatus and the communication equipment separately; the real-time acquisition apparatus and the communication equipment are integrated together; and the 220V mains supply, the electric control change-over switch, the rectifier circuit, and the real-time acquisition apparatus are all connected with the monitoring apparatus. The direct current power supply system is simple in structure, creative in design, capable of monitoring the operating conditions of the communication equipment in real time through the local area network, switching off all the electric power sources of the equipment through the electric control change-over switch, and avoiding manual intervention, convenient to maintain and detect, and safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a communication DC power supply system. Background technique [0002] At present, most of the communication equipment in the communication room are powered by DC 48V power supply. The DC 48V power supply system is the source of power for communication equipment and the basic equipment of various communication equipment. It is called the heart of communication equipment. Once the DC 48V power supply system used online is put into use, the operation of online communication equipment will be affected due to power failure. , so generally online DC 48V power supply equipment systems are rarely repaired, maintained and overhauled after power outages, let alone online tests, and even some communication equipment DC 48V power supply systems have not been fully overhauled since they were put into operation and scrapped. In addition, once the DC 48V power supply equipment f...

The DC 48V power supply system is the source of power for communication equipment and the basic equipment of various communication equipment. It is called the heart of communication equipment. Once the DC 48V power supply system used online is put into use, the operation of online communication equipment will be affected due to power failure. , so generally online DC 48V power supply equipment systems are rarely repaired, maintained and overhauled after power outages, let alone online tests, and even some communication equipment DC 48V power supply systems have not been fully overhauled since they were put into operation and scrapped. In addition, once the DC 48V power supply equipment fails, it can only rely on battery discharge to support the operation of the communication equipment in a short period of time, but if the time is slightly longer (such as more than 1 to 2 hours), when the load capacity of the battery is exceeded, the communication system will be paralyzed and the battery will be greatly damaged. In addition, when the communication DC 48V power supply equipment is repaired, the communication equipment part must be restarted, so Once the DC 48V power supply system fails, the failure caused by the communication equipment will last for a long time. It will also prolong the repair time and have a greater impact on online communication equipment
