Is the UPS power supply to maintain the battery to maintain maintenance regularly? Many users think that the maintenance of the UPS power storage battery is not maintained, this is a big misunderstanding. The full name of the non-maintenance battery is a lead-acid valve-free maintenance battery. "Maintenance" refers to not measuring the specific gravity of the battery, do not power the water, but not to maintain.
Today, the UPS power manufacturer introduces some maintenance methods. Is the UPS power supply to maintain the battery to maintain maintenance regularly? When using the maintenance-up UPS power battery, simply believe that maintenance is not required. Generally, the service life of the automotive battery is about 2 years, if maintenance is, it can reach 3-4 years.
At present, there are still many misunderstandings on the maintenance of the UPS power supply to protect the battery, leading to early damage to the battery, should cause us to pay attention. The UPS power battery is generally regular maintenance once a year to reduce accidental failures in UPS operations. The important use of the UPS power battery is an important device to supply uninterrupted power supply services, extensive applications in important places.
Like machine room, data center, etc., the UPS power supply will be affected by factors such as environment, it is necessary to maintain the UPS power supply from time to time to prevent operation failure. UPS is widely used is a maintenance-free sealing lead-acid battery.
Its price is more expensive, about 1/3-1 / 2 of the total UPS cost; actual maintenance also shows that there are about 50% UPS power supply The fault is related to its battery. A large amount of UPS fails, the first is expensive battery. Therefore, the necessary maintenance for the UPS battery pack is the key to extending the service life of UPS.
UPS power supply lead-acid battery daily maintenance method 1, maintaining a suitable ambient temperature, affecting factors affecting UPS supply battery life. General ambient temperature required by the general battery manufacturer is between 20-25 ° C. Although the temperature rise has improved on battery discharge capacity, the cost of pay is a big shortened battery life.
According to test assay, once the ambient temperature exceeds 25 ° C, 10 ° C per liter, the battery life should be shortened. Second, the floating voltage and discharge voltage in the regular charging discharge UPS power supply, all debugged to the rated value during the factory, and the size of the discharge current increases with the increase of the load, and should be reasonably adjusted reasonably. For example, the number of applications such as electronic devices 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. Third, the communication function is currently, the vast majority, 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. Third, timely replacement of waste / bad batteries Currently, the number of batteries equipped with large and medium-sized UPS power supplies, from 3 to 96 不, even more. These single batteries constitute a battery pack through a circuit connection to meet the UPS DC power supply.
In the continuous operation of UPS, due to performance and quality differences, individual battery performance is lowered, and the storage capacity does not meet the requirements and is inevitable. When a certain / some batteries in the battery pack are damaged, the maintenance personnel should check each UPS power battery to exclude damaged batteries. When replacing new batteries, you should strive to purchase a battery with a model of the same model, prohibiting an anti-acid battery and a sealed battery, a battery of different specifications.
When the UPS power storage battery is used, when using the UPS power supply, it should be necessary to comply with the relevant provisions of the product manual or the manual to ensure that the fire line, zero line, ground line meet the requirements, the user may not change its mutual order. Strictly operate according to the correct boot, shut down sequence. Preventing the voltage output of the UPS power supply due to the sudden loading or sudden drop of load fluctuations, but makes the UPS power supply cannot work properly.
It is strictly forbidden to close and turn on the UPS power supply. Generally requiring at least 6 seconds after closing the UPS power battery, the UPS power supply can be turned on, otherwise the UPS power supply may enter the state of "startup failed", that is, the UPS power supply enters the none of the main market, and there is no inverter output. It can therefore be seen that the UPS power supply free maintenance and maintenance of the battery, which can not only guarantee power supply, but also extend the useful life of UPS and prevent damage!.
