Communication power supply is one of the infrastructures in the entire communication network. It is a system specially used by communication enterprises to provide power energy support for communication equipment. The stable operation of the communication power supply system plays a vital role in ensuring the stability and reliability of the entire communication network.
Power supply mode of communication power supply
The power supply mode of communication power supply can be divided into centralized power supply, decentralized power supply and hybrid power supply. Among them, decentralized power supply is to install the power supply equipment directly next to the communication equipment and transmit power to the communication equipment through cables. This method has the advantages of flexible wiring and convenient maintenance, but it also has problems such as unstable power environment and low power efficiency. Centralized power supply is to connect multiple communication equipment to the same power supply system and supply power through a unified power supply equipment. This method has the advantages of high power efficiency and convenient maintenance, but it also has problems such as difficult wiring and high power environment requirements.
In order to ensure the stability and reliability of the communication power supply system, a variety of technical means need to be adopted for protection. First of all, it is necessary to use high-efficiency and high-reliability power supply equipment, such as switching power supply, UPS, etc. Secondly, it is necessary to adopt reasonable power supply methods and wiring schemes to avoid problems such as unstable power environment and overheating of lines. In addition, intelligent monitoring technology is also needed to monitor and record the operating status of the communication power supply in real time, and to detect and handle faults in time. The communication power supply is an indispensable part of the entire communication network, and its stability and reliability directly affect the operating quality and reliability of the entire communication network. Therefore, we need to continuously strengthen the research and application of communication power supply technology, improve the efficiency and reliability of communication power supply, and provide more stable and reliable services for people's communication and life.
Technology used in communication power supply
1. Switching power supply technology: Switching power supply technology is an efficient power conversion technology that converts the input DC voltage into the required DC output voltage through a high-speed switching circuit. Switching power supplies have the advantages of high efficiency, small size and light weight, so they have been widely used in communication power supplies.
2. Distributed power supply technology: Distributed power supply technology is a technology that decentralizes and modularizes the power supply system. Through the parallel connection and redundant design of multiple modules, efficient, reliable and flexible power supply methods are achieved. This technology can effectively improve the reliability and maintainability of the power supply system and reduce the impact of system failures on communication equipment.
3.Series resonance technology: Series resonance technology is a power technology that uses the resonance principle for transformation. By adjusting the parameters of the circuit, the circuit can produce resonance at a certain frequency, thereby achieving efficient energy transfer. This technology has been widely used in communication power supplies and can effectively improve the efficiency and reliability of the power supply.
4. Soft switching technology: Soft switching technology is a technology that controls the voltage, current or frequency of the switch to soften or soft switch the switch during the opening and closing process. Soft switching technology can improve the efficiency of the switch, reduce the loss and noise of the switch, so it has been widely used in communication power supplies.
5. Thermal management technology: Thermal management technology is mainly to solve the problem of power supply equipment running in a high temperature environment. Thermal management technology includes heat dissipation design, heat pipe technology, liquid cooling technology, etc., which can effectively improve the heat dissipation efficiency of power supply equipment and ensure the stable operation of the equipment.
6. Intelligent monitoring technology: Intelligent monitoring technology mainly monitors and records the operating status of communication power supply in real time, detects and handles faults in time, and ensures the normal operation of power supply equipment. Intelligent monitoring technology can also realize remote management and control, improve management efficiency and maintenance level.
In summary, there are various technologies used in communication power supplies. The application of these technologies can effectively improve the reliability and efficiency of communication power supplies, ensure the normal operation of communication equipment, and provide better services for people's communication and life.
