What are the application of communication power supply in communication rooms?

Communication power supply is a critical infrastructure for the entire communication network.

The communication power supply system is the heart of the communication system. A stable and reliable communication 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 causes power interruption to the communication equipment, the communication equipment cannot operate, resulting in communication circuit interruption, communication system paralysis, and significant economic and social benefits losses. Therefore, the communication power system occupies a very important position in the communication system.

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 10 seconds, it is judged as a system fault. Any voltage, frequency, or waveform distortion in the original communication system that exceeds the specified range and lasts for more than 60 seconds is considered a fault. To ensure the reliability of the communication power system, communication departments with conditions should try to introduce two different mains power inputs from two different places and set up automatic switching devices for two mains power inputs; The equipment used should be high-frequency switch rectifier equipment with high reliability, adopting a modular and hot swappable structure for easy replacement, and reasonably configuring backup equipment. No new technology or equipment shall enter the power supply system without sufficient verification and trial operation. The power supply method should vigorously promote decentralized power supply, and communication equipment using the same DC voltage should adopt two or more independent power supply systems. This is also a new requirement for the continuous expansion of communication network capacity and scale, as well as the introduction of various new industries in the future. In order to minimize the average time to repair equipment failures, it is necessary to regularly analyze operating parameters, predict the time of failure occurrence, and promptly troubleshoot. We also need to improve our technical maintenance level by adopting centralized maintenance, remote signaling, and telemetry maintenance.

Implementing 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 reducing staff and increasing efficiency in enterprises. Various power equipment should be intelligent, standardized, and comply with open communication protocols. In the implementation process, the setting of the three remote points should be reasonable, not the more the better. Reliability and practicality should be the basic principles, and simplicity should be avoided. In this regard, NASN has achieved unmanned power supply by using remote signaling, telemetry, remote centralized maintenance and other functions of the power supply system. When the power supply system encounters obstacles, the system automatically sends a paging message to maintenance personnel.

Power technology is the fundamental technology that supports the operation of various electronic devices, and its level of development directly affects the speed and quality of the entire electronic information industry. With the rapid development of new generation communication technology, new energy vehicles, and industrial automation, the demand for power technology is also increasing. The innovation and application of power technology will bring higher efficiency, lower costs, and better experiences to these fields.
