Analytics analysis and processing method of maintenance of domestic UPS battery maintenance. According to statistics, the UPS battery in my country has not installed monitoring equipment in China, and more than 90% of the UPS batteries do not carry out the necessary maintenance. This is a major hidden danger for the UPS power supply failure in the future.
Therefore, the maintenance of the UPS battery is very important, it is also very necessary. Domestic UPS Battery Maintenance Status UPS Battery Maintenance Similar to the maintenance of the general low voltage system battery Periodically measure each battery-side voltage, when each battery pressure difference is too large, it is necessary to perform a full charge, and the battery is required to perform a test capacity experiment or depth discharge to check the performance of the battery pack and maintain the activity of the battery. However, in practice, due to various conditions, there are few people's maintenance of the UPS battery, which is fully carried out in the above.
First, the new battery is accepted, due to long, there is no convenient tool for utilization, there are quite a few people at all Do this is to use the battery in use. According to statistics, about more than 95% of the UPS batteries in my country lack the necessary maintenance. This is a hidden danger for the UPS power supply failure in the future; secondly, after the new battery is put into use, due to the general UPS battery It is installed in the cabinet, measure, detachment is inconvenient, rarely measuring the end voltage, and regular depth discharge is nothing.
There is a condition that the majority of maintenance personnel can do only for every other time, closed the city's electricity to discharge the actual system for a while, in order to keep the battery pack to keep the battery, and the performance of the battery The remaining capacity of the advantages and disadvantages and the remaining capacity of each battery is still unless. UPS Battery Maintenance Processing Method 1 Prevent the load current to the UPS impact, so that the UPS is extended. It is possible to see the inverse process of the boot order, first enclose the load one by one, and then close the UPS.
2. Before booting before boot, first confirm that the polarity of the input market is not correct to ensure personal safety. Pay attention to the total power of the load that is not greater than the rated power of UPS.
It should be prevented from working in overload to ensure that UPS can work properly. 3. After the shutdown, the UPS battery pack is powered and automatically turned off.
Do not use the UPS battery pack to prevent the battery from being damaged due to excessive discharge. When the output is abnormal, it is turned to the UPS battery pack, and it should be closed in time and shut down. 4.
However, dust-proof problems also plague UPS, UPS's use environment requires cleaning, dust, dry, dust and humid environment to cause UPS work is not normal. The UPS battery has a higher temperature requirements, and the standard use temperature is 25 ¡ã C, and it is best not to exceed 15 ¡ã C ~ 30 ¡ã C. 5, battery maintenance UPS battery pack will have self-discharge phenomenon, if long-term placement does not cause damage to the battery pack, therefore to be charged and discharge regularly.
If used is the maintenance-free absorption electrolyte system battery, there will be no gas during normal use, but if the user uses improper use, the battery pack excess charging will be born with gas, and there is an increase in battery pack internal pressure. The situation is severe, and the battery can be increased, deformed, and the leakage is even broken. If the user finds this phenomenon, the battery pack should be immediately replaced.
6. Pay attention to the safety because the battery pack voltage is very high, there is a certain electric shock danger of the human body, so it should have a security guarantee when loading and unloading the conductive connection strip and output line, and the tools adopted should be insulated, especially the output contacts should have alert. Electric shock setting.
7. The charging voltage is in the charging process of the UPS, if the charging voltage is too high, it will cause excessive charging of the battery pack, and it will cause the battery pack to charge insufficient. When the charging voltage is abnormal, the battery configuration data may be born.
Therefore, when installing the battery pack, you must pay attention to the correctness of the battery specification and quantity, different specifications, and different brands should try to prevent mixing, and the external charger is also best not to use low-cost inferior products. 8. The charging current is similar to the voltage requirements of the UPS.
When charging and disculating the UPS battery pack, it should be used to prevent excessive current. Although sometimes the UPS battery pack can accept a certain degree of large current, but should be avoided as much as possible in actual operation, otherwise the battery polar panel will be deformable, resulting in an increase in the internal resistance of the battery, and the battery capacity will be severely decreased. Battery pack life is shortened.
The above is the domestic UPS battery maintenance status and treatment method analysis, generally normal UPS, its battery life is 3 ~ 5 years, but there is currently a considerable part of the UPS battery in China to start problems in less than 1 year, this aspect The original is important because the lack of necessary maintenance has caused. It is worth noting that many units are not clear from the health status of the UPS battery, and leave hidden dangers in the UPS system for the lack of the necessary detection and maintenance mea.
