Selection and maintenance of oulite battery in communication base station (II)
2 installation of oulite battery for communication base station
2.1 location selection of battery installation
The working and storage place of the battery should be clean, ventilated and dry. Sparks, flames and other igniters are strictly prohibited, and fire extinguishers should be equipped. The installation place of the battery should be away from heat sources and places prone to sparks, avoiding rabbits
Direct sunlight, no organic solvents and corrosive gases around. At the same time, the air vents of the air conditioning or ventilation system should also be avoided to directly affect the temperature of the battery cell, resulting in uneven battery voltage.
2.2 temperature requirements for installation of oulite battery communication base station
The working environment temperature of the battery system is generally required to be between 15 ℃ and 30 ℃. Since the battery operates best at a temperature of 25 ℃, it is necessary to install an air conditioner to ensure that the battery has better performance
Performance and longer service cycle.
2.3 requirements for storage battery installation space
There should be enough space to install the battery. Since there are many ways to install the battery, the single body can be placed vertically and horizontally, and the whole group is installed from single layer to double layer and multi-layer, it is not clear how to
Installation is the most appropriate, but several principles should be mastered:
(1) It is convenient to detect the voltage of each single battery;
(2) Facilitate the replacement of each single battery;
(3) It is convenient to observe the appearance of each single battery (whether the acid overflow on the surface and the corrosion of pole and connecting strip can be seen);
(4) There should be a certain gap between the single batteries to facilitate the heat dissipation of the battery.
2.4 bearing capacity of the installation floor of oulite battery
As the main raw material of valve regulated sealed lead-acid battery is lead, everyone knows that the proportion of lead is the largest in common metals. The battery is small and heavy. When installing, we should comprehensively consider the size of space
For the bearing capacity of the ground and floor, it is generally recommended to use single-layer tiling on the floor to increase the contact area and reduce the pressure per unit area, in strict accordance with the load capacity of floor installation provided by the state and manufacturers
3. Maintenance of oulite battery in mobile communication base station
3.1 maintenance rules
Floating charge voltage: the normal floating charge voltage under the ambient temperature of 25 ℃ is 2.23v~2.25v/ monomer. The temperature compensation coefficient is: -3.5mv/ ° C. When the battery is floating, the voltage of the battery is not
It should be lower than 2.18v. If the unit voltage is lower than 2.18v, equalizing charging is required.
Equalizing charge (i.e. equalizing charge): equalizing charge is generally charged with constant voltage and current limiting, and the charging voltage is 2.35v/ monomer (ambient temperature 25 ℃). The temperature compensation coefficient is: -5mv/ ° C. Equalizing frequency
Usually once every two months.
(5) Whether the connection is loose (the newly installed battery needs to be tightened once every six months, and generally once a year in the future).
Actual case: in the process of battery maintenance, some battery poles were found to be loose, but most of them were found on newly installed batteries, and they were all seriously connected falsely, resulting in the abnormal use of batteries.
