Communication power supply is an important part of the whole communication network equipment. Just like the heart of the human body, the quality and reliability of power supply of power supply equipment will directly affect the whole communication and its quality.
If the power supply fails, the communication will be blocked or the communication quality will be reduced. This will affect the country's economic construction, people's lives and international exchanges. Therefore, the role of communication power supply equipment is to provide reliable AC and DC power supply for various communication equipment and machine rooms to ensure smooth communication. At the same time, the power supply staff is required to fully master the basic performance, working principle and application method of the power supply equipment, and do a good job in the maintenance of the power supply equipment.
Communication power supply equipment and facilities mainly include: AC mains lead-in line, high-voltage and low-voltage substation equipment, diesel generator set, rectifier, storage battery, DC converter and AC inverter equipment, as well as various AC and DC power distribution equipment.
Communication power distribution is to combine the above power supply equipment into a complete power supply system, which can reasonably control, distribute and transmit to meet the requirements of communication network equipment.

Development status and trend of communication power supply technology in cold channel room, hot channel room and micro-module data center
In the past ten years, China's communications industry has developed rapidly, and the communications network has covered most of the country. The network function is more perfect, the number of fixed phones and mobile phones is increasing rapidly, and communication has become an inseparable part of people's modern social life.
The continuous expansion of network scale and the continuous improvement of consumer requirements put forward higher requirements for network security, progressiveness and service quality of operators. Power supply is known as the heart of communication network and plays a vital role in ensuring the safe and reliable operation of communication network. It is necessary to strengthen the awareness of power supply and increase the investment and maintenance management of power supply.
Communication power supply has been paid more and more attention, and the level of power supply equipment has improved significantly. The daily maintenance and management work is gradually in place, and the phenomenon of major communication interruption caused by power failure is less and less. New technologies and products of communication power supply are constantly applied. The competition between power supply equipment suppliers and between engineering design and construction units is becoming increasingly fierce.
Development status of communication power supply technology in cold channel room, hot channel room and micro-module data center
The DC basic power supply of the communication power supply system is basically unified to - 48V. The simplified and unified DC basic power supply has been recognized by the communication equipment manufacturers and power supply manufacturers, which also brings many convenience to the construction and maintenance of the communication power supply.
The phase-controlled power supply of the communication bureau (station) has been basically eliminated, and the rectifier equipment will be all switch-type equipment. Switching power supply has been rapidly applied to the field of communication with its advantages of high power density, high efficiency, convenient operation and maintenance.
After more than 10 years of development, the valve-regulated sealed lead-acid battery (VRLA battery) has been used for almost all communication batteries. In the process of use, this kind of battery does not need to add acid and water, and it hardly produces acid mist. It can be placed in a room with other power equipment, or even in a room with communication equipment, which provides convenience for the communication bureau (station) to supply power in a decentralized manner.
The quality of domestic power supply equipment continues to rise, and the proportion of domestic power supply equipment has significantly increased, and occupies a leading position. At present, the localization rate of power supply equipment is the highest in the equipment procurement of communication engineering projects.
The automation and reliability of power supply equipment have been significantly improved. Especially in the late 1990s, the promotion and application of centralized monitoring system for power supply and air conditioner environment in communication bureau (station) further promoted the improvement of automation of power supply equipment. Not only are various protection and control functions of the power supply equipment perfect, but also through the monitoring system, the maintenance personnel can sit in the maintenance center, observe the operation of each equipment, and even control the corresponding equipment to change its operation mode.
The new generation equipment has been popularized and applied. Some communication hub buildings have used gas turbine generator units as standby AC power generation equipment, and the equipment operation effect is very good. Compared with the traditional diesel generator, the gas turbine generator unit has the advantages of high success rate of startup, reliable operation, good power generation quality, small volume, light weight, low noise, small vibration, large single capacity, and environmental protection. The disadvantage is that the fuel consumption is large and the price is expensive (the price of imported units is twice that of diesel generator units of the same power, and about 1.5 times that of domestic units). The scheme of using gas turbine generator set as standby generator set in the communication industry is reasonable, and the technology is very mature and has been used for more than 30 years abroad.

(1) Wider use of natural energy
Natural energy is increasingly used in communication bureaus (stations). Since the beginning of the 1990s, a large number of unmanned relay stations of optical cable trunk lines have used solar energy and wind energy for power supply, a considerable number of communication relay stations and mobile communication base stations in northwest China have adopted solar power supply systems, which not only solves the problem of power supply difficulties for communication bureaus (stations), but also saves energy and greatly reduces the maintenance intensity.
(2) The safety of power supply of communication bureau (station) is paid attention to
Lightning protection and fire prevention have been highly valued and guaranteed. Over the years, many communication bureaus (stations) have been struck by lightning due to the failure or imperfection of lightning protection facilities, which has brought great economic losses to operators and also affected the corporate image. In recent years, communication operators have invested a lot of manpower and financial resources to gradually improve grounding and lightning protection facilities to reduce lightning damage losses. From the current situation, the lightning strike phenomenon of the communication bureau (station) after the transformation has been significantly reduced. In order to reduce the possibility of fire in communication bureaus (stations) and equipment, flame-retardant flexible cables are widely used, and the flexible cable industry is easy to lay.
(3) The operating environment of power supply equipment has been greatly improved
Air conditioning equipment is installed in the power room and battery room of most communication bureaus (stations), which improves the operation environment of power equipment and plays a positive role in ensuring the operation indicators of power equipment, especially the life of battery.

It is mainly reflected in three aspects: first, it has established a relatively complete maintenance management system; second, it has generally implemented centralized monitoring and management of the power machine environment of the bureau (station); third, it has updated and configured more advanced maintenance equipment and meters.
1) In recent years, due to the reform measures implemented by the state in the telecommunications industry, several telecom operators have been separated and established, and the veteran comrades of the power supply profession have retired, resulting in the lack of skilled leaders and technicians in the power supply profession itself. However, all communication operators are aware that the system is the guarantee of the production and reputation of an enterprise. If we act according to the system, we can eliminate the harm brought by human factors to the enterprise to the greatest extent. Therefore, while paying attention to personnel training, operators have successively established the maintenance management system of group companies, provincial companies and municipal companies, and formulated the corresponding maintenance management system, which effectively guaranteed the safety of the power supply system.
2) The continuous improvement of the reliability and automation of the power supply equipment has also laid a solid foundation for the unattended communication bureau (station). Since 1995, most communication bureaus (stations) have built centralized monitoring and maintenance management systems for power supply, air conditioning and environment, which has played a significant role in improving the reliability of power supply systems, reducing failure losses and reducing the labor intensity of maintenance personnel.
3) The use of new maintenance tools and meters reduces the labor intensity and work risk of maintenance personnel, and greatly improves labor efficiency. In recent years, the power supply maintenance instruments widely used include battery online capacity tester, power quality analyzer, internal resistance/conductivity meter, infrared thermal imager, infrared thermometer, ground resistance meter, etc.
(5) The development level of domestic communication power supply equipment production has been significantly improved
