The use of UPS power supply is becoming more and more extensive. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine；When the mains power is interrupted, the UPS will immediately supply the 220V AC power to the load through the method of inverter conversion, so that the load can maintain normal operation and protect the software and hardware of the load from damage。
The use of UPS power supply must pay attention to daily maintenance and maintenance, in order to give full play to its role and prolong its service life. The following is a brief introduction to the maintenance method of UPS uninterruptible power supply。
1、 Pay attention to the use environment requirements of UPS
The equipment should be placed to facilitate ventilation, dehumidification and heat dissipation, prevent direct sunlight, keep away from pollution sources, away from heat sources, and maintain indoor hygiene and normal temperature and humidity. The best ambient temperature of the battery is between 20-25 °C。
2、 Regular charge and discharge
Because UPS is connected to the mains for a long time, in the environment of high power supply quality and few mains power outages, the battery will be in a floating charge state for a long time, which will lead to a decrease in the activity of the mutual conversion of chemical energy and electrical energy of the battery and accelerated aging，shorten the service life。
3、 Replace damaged batteries in time
The number of batteries equipped with large and medium-sized UPS power supplies ranges from 3 to 80, or even more. During the continuous operation and use of UPS, due to the difference in performance and quality, the performance of individual batteries declines and the storage capacity cannot reach Damage is unavoidable，When a battery in the battery pack is damaged, the maintenance personnel should check and test each battery, eliminate the damaged battery, and replace the new battery in time, so as not to affect the life of the entire battery pack。
4、 Making the most of battery monitoring systems
Make full use of the battery monitoring system for real-time online monitoring of the battery, which can effectively monitor the internal resistance, temperature, voltage, current, leakage and other important parameters of the single battery，The system can effectively monitor the use of the battery, detect hidden faults in time and issue an alarm, so as to guide the maintenance personnel to deal with it correctly，Extend the life of the battery pack and reduce the total failure rate of the UPS power supply, thereby reducing the probability of power supply equipment accidents。
