1、英文原文： Power system communication power supply test and maintenance of the battery solution Abstract In a large number of data experiments and field application, and on the basis of the telecom room in the power the power of common common problems are analyzed and discussed, from, testing and mainten

2、ance of real-time monitoring system safety, and put forward a set of complete solutions. Keywords: battery group； Power source； Detection； maintenance Introduction The electric power communication system center room equipped with a large amount of storage battery installation, on the communications

3、department.The operation of the electric power systems and support, spare play an important role. But in the maintenance process, or will often meet many problems, a detailed analysis of the below. 1. The battery power supply condition and analyzes the reasons We for large communication machine. Roo

4、m on the actual test, to the battery power supply system for the comprehensive study, found that many rooms, communications equipment have low load capacity battery, system reliability of the poor, in here are two groups of data about battery problems: A. battery service life for the design of the g

5、eneral 8-1 O years, and statistical data show that the battery life ideal circumstances can achieve 4-6 years, generally can not meet the design demand, a large number of telecommunication room used less than 3 years (some two years) appear behind battery, part of the battery even scrapped； B. 2010

6、years urumqi power bureau telecommunication room data show that because the battery electric power communication power supply fault from accidents accounted for 35%, in recent years the data interface rapidly, the ratio has risen to 7%. Two sets of data to show that the problem is more serious batte

7、ry, the battery power supply of security and reliability have a serious threat, investigate its reason, mainly in the following nine aspects: 1.1 battery design process quality The battery design process exists plate technology design, material design, oxygen composite design, the pressure set A com

8、prehensive plan defect, make a battery performance and life have been affected, main performance for battery failure, early leakage water loss, deformation cracks, etc. For simple ascending battery capacity, will the battery plate thin, and increase the number plate, makes the same volume of the cas

9、ing electrolyte reaction area greatly increased, capacity improve soon, but because thin plate, plate easily corrosion, softening battery, service life and therefore greatly shorten, easy to produce the early failure problems. Because of the low pressure setting, charge once to a certain pressure, c

10、ontrol valves will be open Rev., gas is through the valve were leaked, cause the battery fluid loss (usually in a hole or a column valve will find a slightly damp near the liquid), this kind of battery also easy to produce the early failure, valve pressure design and material also has a direct relat

11、ionship between the shell. Due to shell material, oxygen composite efficiency, valve design pressure, and other comprehensive technology lack, some batteries in the process of charging and discharging pool, easy to produce the shell deformation, beat even crack. 1.2 the influence of the operation en

12、vironment Running environment is the main room temperature on battery life influence is bigger, in 25 environment conditions , the environmental average temperature increase every 10 , battery life is reduced by half. Northwest temperature changes greatly (a 30 a + 55 C), the substation telecommunic

13、ation room less equipped with air conditioner, thermal performance is poor, temperature on battery life form directly influence. 1.3 operation mode and installation method Battery packs are generally more battery series into a group, two groups of parallel operation. Site often Found in the internal

14、 battery, article connection (board) corner of battery performance generally have slightly worse, the main reason is the article connection too long (other connection is the article 5 a l0 times) and the materials of the contact resistance caused too large, lead to the connection of pressure drop ar

15、ticle is too big, in the process of charging and discharging, will seriously affect peripheral battery charging and discharging effect, this kind of problem should be avoided. 1.4 the quality of power supply and load design problem The telecom room is located in remote general transformer substation

16、, often without power and the battery in frequent charged, and discharge status, the serious influence battery life. Computer room load relative to the battery capacity are slants small, such as the actual load for 30 A, communications equipment configuration of battery capacity is commonly two grou

17、ps of 300 Ah, the utility after interrupting, storage battery will to tiny current began to discharge, and small discharge current generation of sulfuric acid lead particles is easy to crystallization into pieces and E telecommunication room are generally rural power supply, the quality of power sup

18、ply is not stable, power over A long period of time, power outages frequent, sulfuric acid lead particles generated more easily irreversible sulfate. 1.5 professional testing methods and lack of equipment In the discharge detection, due to lack of monomer detection equipment protection functions, therefore, in discharge only by the group when voltage
