TeleCommunication DC Power Supply

The Telecommunication power supply system is the heart of the communication system. A stable and reliable telecommunication power supply system is the key to ensuring the safe and reliable operation of the communication system. Once the communication power supply system fails and the power supply to the communication equipment is interrupted, the communication equipment cannot operate, which will cause The communication circuit is interrupted and the communication system is paralyzed, resulting in a huge loss of economic and social benefits. Therefore, the communication power supply system occupies a very important position in the communication system.

For communication power supplies, buyers are not limited to telecom operators, but also a huge market for telecom equipment manufacturers. The driving force cannot be ignored whether it is for operators that provide telecommunications services, or for equipment research and development, processing and assembling manufacturing companies.

If the power system cannot output the specified current, the voltage exceeds the allowable fluctuation range, and the noise voltage is higher than the allowable value for more than 10s, it will be judged as a system failure. If the voltage, frequency or waveform distortion in the original AC system exceeds the specified range and lasts longer than 60s, it is judged as a fault. For this reason, to ensure the reliability of the communication power system, the communication department with conditions should try to introduce 2 mains input from two different places, and install 2 mains electric energy automatic switching devices; the equipment used should be highly reliable The high-frequency switch rectifier equipment adopts a modular, hot-swappable structure for easy replacement, and a reasonable configuration of backup equipment. Any new technology or new equipment that has not been fully verified and is not allowed to enter the power supply system before trial operation. The power supply method should vigorously promote decentralized power supply, and the communication equipment using the same DC voltage adopts more than two independent power supply systems. This is also the new requirement for the continuous expansion of communication network capacity and scale and the introduction of various new industries in the future. In order to shorten the mean time to repair the equipment as much as possible, it is necessary to frequently analyze the operating parameters, predict the time when the fault occurs and eliminate it in time. It is also necessary to improve the level of technical maintenance and adopt centralized maintenance, remote telecommunication, and telemetry maintenance.

The implementation of centralized monitoring and management is an inevitable trend in the development of network technology, a requirement of modern communication networks, and an effective measure for enterprises to reduce staff and increase efficiency. Various power supply equipment should be intelligent, standardized, and conform to open communication protocols. In the implementation process, the setting of the three remote points should be reasonable, not as many as possible. Reliability and practicability should be the basic principles, and simple but not complicated. In this regard, our station uses the power system’s remote signaling, telemetry, remote centralized maintenance and other functions. When the power system fails, the system automatically sends paging messages to the maintenance personnel, and the power supply has been unattended.
The power supply system widely uses high-frequency switching power supply system equipment, which has a high degree of intelligence. The battery uses a maintenance-free battery. Although this brings a lot of convenience to users, it should also attract attention in many aspects during use to ensure safe use .
The high-frequency switching power supply system does not require high ambient temperature, and can work normally at minus 5 degrees to 40 degrees, but requires indoor cleanliness and low dust, otherwise dust and humidity will cause the main unit to work disorder. Batteries have higher temperature requirements. The standard operating temperature is 25 degrees, and it cannot exceed +15 degrees to +30 degrees. If the temperature is too low, the capacity of the battery will decrease, and its capacity will decrease by 1% for every 1 degree decrease in temperature. The discharge capacity will increase with the increase in temperature, but the lifetime will decrease. If it is used for a long time at high temperature, the battery life will be reduced by about half for every 10 degrees increase in temperature.
Under normal use of high-frequency switching power supply equipment, the maintenance workload of the host is very small, mainly for dust prevention and regular dust removal. Especially in dry climate areas, there are more dust particles in the air, and dust will be deposited in the machine. When the air is humid, it will cause the control of the main machine to be disordered, causing the main machine to work abnormally, and inaccurate alarms will occur. Another large amount of dust will also cause poor heat dissipation of the device. Generally, it should be cleaned thoroughly every quarter. The second is to check whether the connectors and connectors are loose or not in firm contact during dust removal.
