How much fault occurs when the UPS power supply is used for a long time, and the statistics of UPS maintenance work. Reserve UPS power supply is 50% due to battery triggers. Online UPS power supply is reasonable for designing circuitry, the balance taken by the drive power component capacity, so the power supply circuit is very low, and there is a battery failure rate of 60%.

Therefore, the correct use of maintaining the life of the UPS battery is one of the key factors that reduce the failure of uninterruptible power supply. Method 1 of reducing UPS power battery failure 1. Regularly check the end voltage and internal resistance of each unit battery periodically.

For 12V unit cells, if the end voltage between each unit battery is found to exceed 0.4V or more than 80MΩ or more, the unit cell should be balanced to restore the battery within the battery. Resistance and eliminating the end voltage between each unit battery.

La ŝarĝa tensio prenas 13.5 ~ 13.8V dum ŝarĝo.

Most batteries that have a good balance charging process can restore their internal resistance to 30MΩ. During operation, the UPS power supply is eliminated due to the above-described imbalance of each unit battery characteristics, which is impossible to rely on the charging circuit inside the UPS power supply, so that this characteristic has a significantly unbearable battery. Group, if the offline is not charged in time, its unevenness will become more and more serious.

2. Re-floating the UPS power downtime for more than 10 days, before rebooting, the UPS power supply should be started under the conditions that do not load the load to re-use the charger product electrical circuit to re-carry the battery to the battery 10 to 12h. run.

La UPS-elektroprovizo estas en flosanta stato sen la malŝarĝa procezo, kio estas ekvivalenta al la stato de "stokado.". If this state is too long, the battery has not been scrapped due to "long-term storage", which is mainly manifested as the increase in battery internal resistance, and the internal resistance can reach a few Ω.

We found that after 2 months of room temperature, the battery can be used for about 97% of its rated value. If the storage is 6 months, its use capacity becomes 80% of the rated capacity. If the storage temperature rises, its use capacity will decrease.

It is therefore recommended that the user is best to unplug the mains input every 20 ° C, so that the UPS power supply is operated by the battery to provide energy to the inverter. Tamen, ĉi tiu operacio ne devus esti tro longa, kaj ĉirkaŭ 30% de la ŝarĝo estas ĉirkaŭ 30% de la taksita eligo, ĝi povas esti eligita. How to reduce the failure of the UPS power battery 3.

Reduce the service life of deep discharge electricity is closely related to the depth of it is discharged. Ju pli malpeza estas la ŝarĝo de la elektroprovizo de UPS, des pli granda estas la kvanto de kapablo de la elektra stokado kaj ĝia taksita kapacito, la rilatumo de la rilatumo de la potenca stokado estas, en kiu kazo la baterio estas aŭtomate malŝaltita kiam la bateria tensio estas tro malalta pro la malalta bateria tensio La profundo de malŝarĝo estas relative profunda. How does the actual process reduce the battery in depth? Method is simple: When the UPS power supply is in the middle of the electric power supply interruption, most of the UPS power supplies will be around 4s at the gap 4S when the UPS power supply is powered by the electric power supply.

Periodic alarm sound, notifying the user that now is the battery. When he heard the alarm sound is urgent, the power supply is already in depth, and should immediately perform emergency treatment, close the UPS power supply. Ne devigite, ĝenerale ne lasu la potencon de UPS funkcii ĝis la bateria tensio estas tro malalta kaj la aŭtomata malŝalto finiĝas.

4. Using the high peak charging of the power supply to the UPS power supply for a long time in the market, low-voltage power supply or frequently-stopped power, to prevent the battery from being damaged by the long-term charging, it should be fully utilized to charge the battery to the battery. Ensure that the battery has sufficient charging time after each discharge.

Generally, after the battery is discharged, it is charged to 90% of the rated capacity to at least 10 to 12 h. Note that the charger's selection UPS power supply-free seal battery cannot be charged with a controlled silicon type "fast charger". Ĉi tio estas ĉar ĉi tiu ŝargilo igos la baterion esti en la severa ŝarga stato de "tuja superflua ŝargado" kaj "tuja pasema ŝargado.

Ĉi tiu stato igos la kuirilaron multe malpliiĝi, kaj la baterio estos forigita kiam ĝi estas severa. When using the UPS power supply of the constant voltage cut-off charging circuit, be careful not to adjust the battery voltage too low protection work points, otherwise, it is prone to overflow charging in its initial charging. Kompreneble, estas plej bone uzi ŝargilon, kiu havas kaj konstantan kurenton, kaj konstantan premon.

5. Ensure that the capacity of the power supply ambient temperature battery is closely related to the ambient temperature. Ĝenerale, la agado-parametroj de la kuirilaro estas kalibritaj ĉe ĉambra temperaturo por 20 °C, kaj kiam la temperaturo estas malpli ol 20 °C, la potenca stokado kapablo reduktiĝos, dum la temperaturo estas pli alta ol 20 °C, ĝi disponeblas La kapablo uzata iomete pliiĝos.

Malsamaj modeloj de malsamaj modeloj de malsamaj modeloj diferencas de la grado de temperaturo. Laŭ statistiko, kiam je -20 ° C, la baterio povas atingi nur ĉirkaŭ 60% de la nominala kapablo. La efiko de videbla temperaturo ne povas esti ignorita.
