Maintenance of telecom DC power supply

If the power supply system can not output the specified current, the voltage exceeds the allowable fluctuation range, the noise voltage is higher than the allowable value time and lasts more than 10s, the system is judged to be a system fault. When the voltage, frequency or waveform distortion in the original AC system is beyond the specified range, and the duration is longer than 60s, it will be judged to be a fault. Therefore, in order to ensure the reliability of the telecom outdoor DC power supply, the conditional telecom department should try to introduce 2 power input from two different places as far as possible, and set up the automatic switching device for the 2 way power input; the equipment should use high reliability switching equipment with high frequency, modular and hot plug type structure, so that it is easy to change, and configure backup equipment reasonably. No new technology or equipment shall be entered into the power supply system before being fully verified and tested. Should vigorously promote distributed power supply, more than two independent power supply systems shall be used for telecom equipment using the same DC voltage, this is the new requirements of future telecom network capacity and expedition. In order to minimize the average repair time of the equipment, it is necessary to analyze the operation parameters, predict the time of failure and remove it in time. We should also improve the level of technical maintenance, and adopt centralized maintenance, remote maintenance and telemetry maintenance.
The implementation of centralized monitoring management is the inevitable trend of network technology development. It is also the requirement of modern telecom network and effective measures for downsizing and increasing efficiency of enterprises. All kinds of power equipment should be intelligent, standardized and conform to the open telecom protocol.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
