4g cell phone jammer Mobile communication base station device using DC power supply system to provide energy. Are currently using modular rack power systems, DC lead-acid battery-powered system equipped with floating line consisting of uninterrupted power supply system. Its power supply voltage is -48 V. 4g cell phone jammer rectifier output current capacity depends on the host needs, battery charging requirements, margin requirements, etc. uninterruptible power supply considerations.
The current modular rack power system with the application of an extremely wide range, each factory especially well-known brand of professional plant, on its features, performance and technical indicators have already made a lot of progress, and its main features are:
(A) take full account of the small size, light weight, easy installation and maintenance requirements;
(2) standardized, modular, hot-swappable rectifier modules;
(3) to adapt to a wide voltage range;
(4) take full account of the anti-lightning surge and other needs;
(5) support for supply management system for background unattended functional requirements;
(6) may be considered the best technology for battery management functions;
(7) fully considered the primary and secondary special circumstances under electricity demand;
(8) Other safety and reliability of the design, such as anti-seismic capability.
Of course it is undeniable that different manufacturers on the device selection and manufacturing process level, but also some differences do exist, there are some differences lead to stability and reliability of equipment operation, or even mixed. 4g cell phone jammer
Because of the importance of this, the power of the maintenance work very clearly.
General characteristics of two mobile base stations
General characteristics of mobile base stations:
(1) AC power complex. Some three-phase power, some for single-phase power supply, some State Power Line served, but there are also delivered to a dedicated high voltage transformer, the transformer capacity line distance problem size and low side; others may have a direct and connected in the rural power, residential electricity production lines or factories and mines electricity lines; which may lead to poor quality of power supply, such as a wide range of voltage fluctuations, voltage mutations occur frequently, often frequent power failures.
(2) number of base stations, widely distributed, large differences in site environment. For network coverage and had a large number of base stations built in the wild mountains, houses the high ground, hot and humid zones, which not only led to the AC power is difficult, but also lead to increased probability of lightning, high temperature and humidity resulting in equipment operation stability and lifetime reduce the failure rate rise.
(3) unattended. High direct costs for manual intervention when problems arise not only repair and restoration, and the failure to timely discovery 'back stop' to bring customer impact and indirect losses are also high. 4g cell phone jammer
These general characteristics of the base station power supply assurance and maintenance work resulted not only increased workload, but also increase the difficulty, some power failure and event handling for maintenance personnel skill level requirements are also greatly improved.
Three pairs of power to maintain several specific recommendations
Based on the above basic introduction, the paper mainly on supply assurance and supply maintenance mention a few specific recommendations: 4g cell phone jammer
