Analysis of UPS power battery installation requirements and maintenance methods

UPS power supply battery installation requirements 1. The equipment installation site should be a level hard ground. If it is an anti-static raised floor, the bearing capacity of the floor should be considered, and the steel bracket should be designed and manufactured according to the weight of the equipment. The site should be able to get all necessary services, especially good ventilation with light and electric charge. 2. The UPS power storage battery site should be free of dust, especially conductive dust, otherwise it may cause a short circuit within the equipment and affect the reliable operation of the UPS battery. At the same time, the site should not have or be near a heat source to ensure the environment specified by the equipment. 3. In order to facilitate operation, equipment maintenance and equipment heat dissipation, at least 50~100cm of space should be left around the equipment cabinet and 100cm of space should be left on the upper part. When designing the cooling and ventilation system of the computer room, it is necessary to consider the heat generated by the UPS power supply. 4. The working environment temperature of UPS battery should be 0~35℃, and the best temperature is about 25℃. The best humidity is 30%~70%. 5. The battery should be away from heat sources and places prone to sparks, and the safety distance should be greater than 0.5 meters. 6. The storage battery should be protected from direct sunlight, and can not be placed in a closed container, and can not be placed in an environment with radioactive, infrared radiation, ultraviolet radiation, organic solvent gas and corrosive gas. 7. The storage battery room should have regular lighting and accident lighting, and its lighting fixtures should be arranged above the walkway. 8. The floor of the storage battery room should have sufficient bearing capacity. When the storage battery is arranged on the floor, the load requirements should be supplied to the design. It is good to arrange the UPS power battery in a separate storage battery room, and there should be enough space around the battery pack for ventilation and maintenance of the battery. UPS battery maintenance methods ● Maintain a proper ambient temperature Generally speaking, the major factor that affects the battery life is the ambient temperature. Generally, the best ambient temperature required by battery processing manufacturers is between 20°C and 25°C. Although the increase in temperature improves the discharge capacity of the battery, the price paid is that the life of the battery is greatly shortened. According to the test, once the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase. At present, the batteries used in UPS are generally maintenance-free sealed lead-acid batteries, and the design life is generally 5 years, which can only be achieved under the environment required by battery manufacturers. If the specified environmental requirements are not met, the length of their lifespan will vary greatly. In addition, the increase of the ambient temperature will lead to the enhancement of the internal chemical activity of the battery, resulting in a large amount of heat energy, which in turn will promote the increase of the ambient temperature, this vicious circle will accelerate the shortening of the battery life. ●Regularly charge and discharge the float voltage and discharge voltage of the UPS power supply, which have been adjusted to the rated value at the factory, and the discharge current is increased with the increase of the load. The load should be adjusted reasonably during use, such as Control the number of electronic devices such as microcomputers used. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the battery will not be over-discharged. Because UPS is connected to the mains for a long time, in an environment with high power supply quality and few mains blackouts, the battery will be in a floating state for a long time, which will cause the battery's chemical energy and electric energy to convert between the activity and accelerate the aging. And shorten the service life. Therefore, it should be completely discharged every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the size of the load. After a full-load discharge is completed, charge it for more than 8 hours according to regulations. ●Using the communication function At present, most large and medium-sized UPSs have operational performance such as communication with a computer and program control. Install the corresponding software on the microcomputer, connect the UPS through the serial and parallel port, and run the program, you can use the microcomputer to communicate with the UPS. Generally, it has functions such as information query, parameter setting, on-time setting, automatic shutdown and alarm. Through information query, you can obtain information such as mains input voltage, UPS output voltage, load utilization, battery capacity utilization, internal temperature and mains frequency; through parameter settings, you can set the basic characteristics of UPS, battery life and The battery runs out of warning, etc. Through these intelligent operations, it greatly facilitates the use and management of the UPS power supply and its storage battery. ●Replace waste batteries in time. At present, the number of batteries equipped with large and medium-sized UPS power supplies ranges from 3 to 80, or even more. These individual batteries are connected by circuits to form a battery pack to meet the requirements of UPS DC power supply. In the continuous operation and use of UPS, due to the difference in performance and quality, it is inevitable that individual batteries will be damaged due to performance degradation and insufficient power storage capacity. When some batteries in the battery pack are damaged, the maintenance personnel should inspect and test each battery to exclude the damaged battery. When replacing new batteries, you should strive to buy batteries of the same manufacturer and the same model, and it is forbidden to mix acid-proof batteries, sealed batteries, and batteries of different specifications.
