Outdoor Power Feasibility of underground storage battery
1 Introduction
With the construction and development of communication networks in order to solve the blind spot coverage of the network, has emerged a large number of base stations, outdoor and outdoor-type communications equipment. Because these facilities long-distance communication in hostile environment external communication equipment necessary for the uninterrupted supply problem has plagued the industry is a major problem.

Power of communication itself can in principle respond to the harsh environment outdoors, the real bottleneck is to use external battery. Battery outdoors in the difficulties of current installation, easy to fly, and the battery life is particularly affected by temperature. How to solve the impact of the external environment of the battery, extending its life is essential. The technology used in the comparison of several methods of storage battery in the open air on the method proposed underground ventilation battery type, design, application of the breakdown of battery cabinets underground, outdoor power supplies combined with the enhanced surveillance system to solve the temperature outside the impact on battery life as well as the underground Cabinet battery may experience problems in the wet gas exchange.
2 The purpose and significance
Underground battery cabinets, ventilation air could solve the outdoor base station uninterruptible DC power issues, increasing the lifespan of the battery to external power, reduce the use of integrated cost of base station outdoor, overall energy consumption for communications equipment outdoors for long outdoor use has opened a feasible way.

3, the situation at home and abroad
Underground battery for use at home and abroad have reported, but buried in the wet gas corrosion of the battery cabinet batteries, thus reducing the issue of battery life. For this question, there is no good solution. The methods described in this document by the communication power of the system of supervision, the cabinet humidity control intelligent battery fan ventilation underground battery, thanks to the effective implementation, the better for resolve this problem battery life, improved significantly. The technology is still blank in China, the promotion of greater importance.
4 The general idea
(1) battery-buried form of telecommunications equipment in the solution of the problems of supply, ensure better security, the effects of dust, reducing the effects of outside temperature on the battery life, autonomy extended battery. FRU 92P1141 battery IBM ThinkPad R32 battery
(2) Battery cabinet buried the versatility of 2V or 12V battery, the battery life 2V to 12V battery, the basic methods are used underground 2V battery.
(3) Through the underground cabinet ventilation fans installed battery airways, humidity sensors, humidity cabinets to collect data.
(4) By the communication power of the monitoring unit monitors the battery drawer of the moisture indicator on the frequency of ventilation.
5. technical programs
(1) Battery box material selection and processing structure
Taking into account the battery case long buried in moist soil, must be made using the plastic box. Meanwhile, because a larger boxes, more specifications, not by the method of injection molding, welding sheet metal uses. Thickness is 12 mm to 15 mm.
(2) The placement of the battery and support
Given the plastic box from the battery itself is strong enough to hold the battery so that the bottom of the battery box with plastic flatbed platform to support the weight of batteries. If the site is not convenient for masons work can also be prefabricated concrete slabs. IBM ThinkPad R40 battery IBM ThinkPad X60 battery
(3) The waterproof battery box
The battery box is sealed by welding to achieve the goal. Between the battery box and cover with waterproof tape, and adoption of appropriate measures to waterproof tape attachment compression to achieve the goal of sealing. In addition, the battery box, the lid and connecting PVC pipe with a welding method.
(4) Battery box, air cooling
The battery in the trial of a small quantity of gas, the battery box will be acid gases, moisture, the need to unload. First, through the intake pipe, the exhaust pipe of the agreement itself, can achieve natural breathing. In addition, fans have been installed in the exhaust pipe end by means of dry contact connection, control switching power supply of the independent monitoring unit, about 10 minutes a day and regularly required traffic, which can discharge the battery box of sulfur dioxide, moisture.
Food switching by an independent external monitoring unit, to facilitate the implementation of control of the fan. toshiba pa3285u-2bas toshiba pa3285u-2brs
To prevent debris through the intake manifold, exhaust pipe in the casing of the battery in the intake manifold, exhaust pipe exits insect net.
(5) Security issues battery box
With the battery box and the lid is installed between the access control, battery and cover separation, may alarm.
6 Economics
General installation and underground installation, there are many gaps in comparison, for example: ① general safety problem of installing the most difficult questions; ② existence of the H rod bearing common installation problems; ③ Installation The most common can be used 200Ah battery, and buried the installation did not have this restriction.
7 Conclusion
From the above analysis we can see that the battery cabinet, the ventilation of underground air to save 10,325 yuan per year per site, if the new 200 site in Longyan annual basis, the annual investment will allow save 10,325 yuan × 200 sites / site = 2.065 million yuan. toshiba pa3285u-1bas toshiba pa3285u-1brs
With the development of mobile services, the number of stations will be outdoors more and more is spent batteries in outdoor conditions is increasing. According to the construction of the current speed of Fujian Mobile, the new stations marginal 2000, if the battery used in all ventilation systems underground Fujian Mobile and annual savings will reach 20.65 million yuan investment.
Increasingly tight energy supply in the current international situation, China has strongly advocated the conservation of energy. Underground ventilation air through the use of how the battery cabinet, battery life or more than 3 times the initial rise, each site can save each year to reach million more than expenditures. If a promotion at the national level, the state will save a lot of resources, promotion of high value. toshiba pa3191u-4brs toshiba pa3284u-1brs
