Communication power supply is the key infrastructure of the whole communication network, but communication power supply does not account for a large proportion in the whole communication industry. Telecom operators' purchases of power supply products are mainly for annual equipment maintenance and system equipment, of which the maintenance of power supply equipment usually accounts for a higher proportion of purchases. The annual cost of telecom operators for the construction of power supply systems is relatively small, unless the telecom system needs large-scale upgrading or expansion, the operators will increase the procurement of power supply equipment.

Communication power supply system is the heart of the communication system, stable and reliable communication power supply system is the key to ensure the safe and reliable operation of the communication system, once the communication power supply system failure caused by the interruption of power supply to the communication equipment, the communication equipment can not run, will cause the interruption of communication circuits, the communication system is paralysed, which results in a great loss of economic and social benefits. Therefore, the communication power supply system in the communication system occupies a very important position. For communication power supply, the buyers are not limited to telecommunication operators, there is also a huge market of telecommunication equipment manufacturers. Power is not to be ignored either for the operators who provide telecommunication services, or for the manufacturing enterprises who research and develop, process and assemble the equipment. China is the world's famous manufacturing base, which also objectively creates a strong market pillar for power products, these will undoubtedly help the communications power supply industry to successfully pass the winter of the market. Mobile phone battery is an important part of the communication power supply, and in recent years the mobile phone market boom wave after wave, the communication power supply if you can adjust their own strategies in time, may also be able to gain in the field of mobile phone battery.

If the power supply system can not output the specified current, the voltage exceeds the permissible fluctuation range, the murmur voltage is higher than the permissible value of time and lasts for more than 10s are judged to be a system failure. The original AC system in the voltage, frequency or waveform distortion beyond the prescribed range of duration greater than 60s are judged to be fault. To this end, to ensure the reliability of the communication power system, conditional communication departments should try to introduce 2-way utility input from two different places, and set up 2-way utility power automatic inversion device; the equipment used to select high reliability high-frequency switching rectifier equipment, using modular, hot-swappable structure to facilitate the replacement, and reasonable configuration of backup equipment. Any new technology, new equipment without full verification, test run before they are not allowed to enter the power supply system. Power supply mode should vigorously promote decentralised power supply, using the same DC voltage communication equipment using more than two independent power supply system, which is also the future capacity and scale of the communications network continues to expand, the introduction of a variety of new industry new requirements. In order to minimise the average fault repair time of equipment, it is necessary to frequently analyse operating parameters, predict the time of faults and eliminate them in a timely manner. It is also necessary to improve the level of technical maintenance and adopt centralised maintenance, remote telecommunication and telemetry maintenance.

The implementation of centralised monitoring and management is an inevitable trend in the development of network technology, a requirement of modern communication networks, and an effective measure for enterprise staff reduction and efficiency. All kinds of power supply equipment should be intelligent, standardised and conform to open communication protocols. In the process of implementation, the setting of the three remote points should be reasonable, never the more the better, and should be based on the basic principles of reliability and practicability, and should be simple rather than complicated. In this regard, our station has realised unattended power supply through the functions of telecommunication, telemetry and remote centralised maintenance of the power supply system, which automatically sends out paging information from the system to the maintenance personnel when the power supply system is in trouble.
