Many people think that the battery is not maintained, especially when using the UPS power supply, this idea is more clear. But in fact, due to the lack of maintenance of the battery is quite high in all faults in UPS. Therefore, routine routine for maintenance of the battery of the UPS, greatly extend the battery life of the UPS and reduce the fault rate.
This article will analyze the maintenance of UPS batteries for everyone. Maintaining a suitable ambient temperature usually affects factors that affect battery life is ambient temperature. The best ambient temperature required for general battery packages is between 20-25 ¡ã C.
Although the temperature rise has improved on battery discharge capacity, the cost of pay is a big shortened battery life. According to experimental assay, once the ambient temperature exceeds 25 ¡ã C, 10 ¡ã C per liter, the life of the battery is shortened. At present, the battery used by the UPS is generally maintenance-free sealing lead-acid battery, and the design life is generally 5 years, which can reach in the environment requested by the battery.
Without the prescribed environmental requirements, the length of life is very different. In addition, the ambient temperature increases, causing the internal chemical activity of the battery, there is a lot of thermal energy, which will increase the ambient temperature rise, which will speed up the life of the battery. The floating voltage and discharge voltage in the regular charging discharge UPS power supply are debugged to the rated value during the factory, and the size of the discharge current increases with the increase of the load, and the load should be reasonably adjusted reasonably, such as control.
Number of applicants such as electronic equipment such as microcomputer. 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 excessive discharge.
UPS is connected to the market due to long-term power supply, and the battery will have a long-term power supply in a long time, and the battery will result in a long time to reduce the activity of battery chemistry and electrical energy to reduce the activity, accelerated aging. Shorten service life. Therefore, it is generally discharged once every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the load size.
After the full load is complete, it will charge more than 8 hours according to the regulations. With the current communication function, most large, medium-sized UPS has operational performance such as microcomputer communication and program control. Install the appropriate software on the microcomputer, connect the UPS through the string / parallel port, run the program, you can use the microcomputer to communicate with the UPS.
Generally have information queries, parameter settings, setup, automatic shutdown and alarms, etc. Through the information query, you can get information on the mains input voltage, UPS output voltage, load utilization, battery capacity utilization, temperature and market frequency; through parameter setting, the basic characteristics of UPS can be set, the battery can last time and Battery for agency, etc. Through these intelligent operations, it greatly facilitates the management of UPS power supplies and its battery.
Timely replacement of waste / bad batteries Currently, the number of batteries equipped with large and medium-sized UPS power supplies, from 3 to 80, but even more. These single batteries constitute a battery pack through a circuit connection to meet the UPS DC power. In the continued operational use of UPS, due to performance and quality, individual battery performance has decreased, and the storage capacity is not required to be damaged.
When a / some batteries in the battery pack occurs, the maintenance personnel should check the detection of each battery, exclude damaged batteries. When replacing new batteries, you should strive to purchase a battery with a model of the same model, prohibiting an antagonized battery and a sealed battery, different specifications of batteries. This article gives four ways to extend the working life of the UPS battery.
In general, it can be summarized as four sentences: suitable temperature, regular charging and discharging, good use of communication function, timely replacement of damaged batteries. There is no university or primary school in the learning of the power supply. As long as you pay attention to observation, you can summarize a variety of features and methods to facilitate our desi.
