|TELECOM:||Spiral Battery Integrated Power System|
With the acceleration of urbanization and an increase in the number of large-scale residential areas, the amount of large-scale communications base station sites becomes fewer and the establishment is more dicult.There is a need to change the original centralized signal transmission to decentralized signal transmitter, therefore the signal coverage area becomes small and power load is reduced. The requirement for the option to install or geographical location of the site is increasingly high,so that an integrated solutions with less space and small bulk is needed to meet the
Our company has developed an integrated design of distributed base station power supply system for a variety of installation environments such as corridor, shaft, and outdoor environment. The UPS, batteries, power distribution are integrated into a cabinet to form an integration power supply system.According to the site environment exibility, it can choose the oor or wall installation, thus provide uninterruptible power protection with high-quality for signal coverage equipment of shopping malls, railway stations, airports, car parks, oce buildings to ensure the comprehensive coverage of the communication signal.
Shoto spiral pure lead battery integrated power system can equip batteries with dierent capacity such as shoto 6-SPB-50/75/100/200 AH according to the users’ load demand, with the following 6-SPB-50 capacity conguration as an example to do a description of the product.
2.2 System Conguration
The integrated system consists of outdoor cabinets, UPS uninterruptible power supply, battery pack, power distribution units.
There are two battery storehouses in an outdoor cabinet, each has two shoto 12V Lead Acid 6-SPB-50AH battery in it,with the interiors install 2 group of thermostat fan and when the ambient temperature is greater than 30 degrees, the fan start working; Moreover , the cabinet is also equipped with two sets of a hot unit for warming the system at low temperatures.
The power distribution unit mainly consist of air switch, including: ①SPD, for access to electricity, and play a role in lightning protection;② AC input, for turning the mains and UPS system, with its upper end paralleled with SPD;③ and ④ are both AC outputs for the user-friendly access to the AC load;⑤ temperature control switch for controlling the on-o of thermostat and mains supply;⑥ and ⑦ are fan thermostat and hot plate temperature, the user can set the starting working temperature;⑧is battery pack and can control the negative on-o of battery pack,the battery pack negative electrode is connected with UPS via⑧.
2.3 System Features
(1) System works
When the mains supply is normal: UPS outputs to the load equipment directly through the switch by the bypass of mains supply, at the same time to charge the battery through the charger.
When the mains supply is abnormal: UPS directly invert into 220VAC or 48VDC to output to the load device from the battery pack through the DC / AC inverse.
(2) Main Applications
◆Communication base station;
◆3G Femtocell station power;
◆High temperature, low temperature area or outdoor base stations which requires short time of back up power;
◆mergency power supply equipment such as emergency communications vehicles.
(3) System Benets Features
◆System conguration can undertake non-standard design according to customer requirements and the size can be adjusted;
◆The high and low temperature performance is matched in the system with Shoto wound pure lead batteries. It has a small volume, high temperature, high power discharge performance, strong environmental adaptability and other advantages;
◆The interior device inside the UPS uses a special coating process, which greatly improve the protection level of system.
◆The maximum system operating eciency up to 96% which is green energy;
◆System power distribution unit is composed of anti-lightning, AC input, AC output, DC output, temperature, battery and other modules, the output shunt size and number can be exibly congured;
◆Integrated power supply system with oor installation, which protection class reaches to IP45, and is totally positively maintained. The system conguration equip with the mounting foot (80mm) and can prevent the rain / snow along the bottom of the inlet into the internal system; It also equip with two sets of fans and temperature control heating plate to cool the system at high temperatures and heat the system at low temperatures with strong environmental adaptability.
