Maintenance issues on the communication power of thinking

Paper Keywords: communications industry, communication power management

Abstract: In the communications industry, the power is often likened to the heart of communication systems. In recent years, the rapid development of telecommunication network round, but also to the maintenance and management work in power who raised many new issues. As power supply is in the coexistence of old and new, progressive replacement of the period. Based on this, the maintenance on the communication power supply and management of a few thoughts.



0 Introduction
reasons for historical development, the current communication power supply system is basically centrally located, centralized power supply based, was on duty, fault-based maintenance. The power of the load, such as transmission, switching, data, mobile and other professional way of moving towards the maintenance of centralized control, centralized maintenance, less or unattended direction. Communication network base stations is an important part of the system to ensure the normal power supply under any circumstances, is to ensure the safe operation of communication networks essential. To this end the communication base stations are equipped with the more advanced power supply system, including switching rectifier equipment, maintenance-free batteries, oil machines. These devices is to protect the stability and continuity of supply of major equipment and maintenance of the quality of these devices, not only affects the life and power system equipment failure rates, and directly related to the communications network running smoothly.


1 Overview
communication power has been from time immemorial, the sun, air, food and water has always been a necessity for the survival of the people, and now in the era of rapid development of science and technology, electricity has become a necessity . Because of electricity, we have the joy of life. It is for the safety of high-quality operation of communication systems, ubiquitous communication power is the solid foundation and the fundamental guarantee. The implementation of centralized monitoring and management of network technology development trend, the requirements of modern communication networks, but also measures corporate downsizing and increasing efficiency. A variety of power equipment to intelligent, standardization, open communication protocols. If the power system can not output the provisions of current and voltage fluctuations beyond the permitted range, noise voltage higher than the permissible value over time and continuous 10s caught judged to system failure. The original AC system voltage, frequency or waveform distortion beyond the prescribed range is greater than the duration of the fault determination thereof 60s. Therefore, to ensure the reliability of power system communications, the communications sector should be qualified in two different places from the introduction of 2-way mains input, and set the 2-way auto-switching power devices electricity; the equipment to use and high reliability high frequency switching rectifier equipment, modular, hot-pluggable for easy replacement of the structure, and the rational allocation of backup device. Any new technology, new equipment without adequate verification, test run before the power supply system are not allowed to enter. Power supply to promote decentralized power supply, using the same DC voltage communications equipment uses two or more independent power supply system, which is the future communications network capacity and scale, the introduction of new industry of new requirements. In order to minimize the average failure time to repair equipment, operating parameters should be regular analysis to predict failure time and immediately removed. But also to improve the level of technical maintenance, the use of centralized maintenance, remote remote, remote maintenance. In the implementation process, the three remote sites set should be reasonable, not the better, to the reliability and practicality as the basic principle should be simple not complicated.


2 power supply systems should pay attention to the problems in power systems are widely used
high-frequency switching power supply system equipment, and its high degree of intelligence, the battery with a maintenance-free batteries, which, although brought to the user Many convenient, but also in the course of attention in many ways, to ensure safe use.

2.1 requirements by the use of power system size and power margin points, to avoid the arbitrary use of additional equipment to increase power, but also does not allow long-term operation under full load. Determine the nature of work in the uninterrupted power system state is almost running to increase the power load or full load condition in the basic work, will result in a rectifier failure, severe damage the converter. Owned generator output voltage, waveform, frequency and amplitude of the power system should meet the requirements of the input voltage, the other power generators switching power supply is greater than the rated input power, otherwise, will cause the power system device is not working or damage.

2.2 should avoid high-current battery charge and discharge, in theory, can accept a large charging current, but in practice should be avoided, otherwise it will cause swelling deformation of the battery plate, making the electrode active material shedding, increased battery internal resistance large and temperature, the capacity will result in severe decline, early termination of life. Under no circumstances should prevent the battery from short circuit or the depth of discharge, because the battery's cycle life and discharge depth. The deeper the discharge, the shorter the cycle life. In the discharge capacity test or repair, usually discharge to 30% -50% capacity on it. Links to Research Papers Download http://www.hi138.com
