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.

Ladespenningen tar 13,5 ~ 13,8V ved lading.

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.

UPS-strømforsyningen er i flytende tilstand uten utladingsprosessen, noe som tilsvarer tilstanden "lagring". 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. Imidlertid bør denne operasjonen ikke være for lang, og omtrent 30% av belastningen er omtrent 30% av den nominelle ytelsen, den kan utlades. 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. Jo lettere belastningen på UPS-strømforsyningen er, desto større er kapasiteten til den elektriske lagringen og dens nominelle kapasitet, forholdet mellom forholdet mellom strømlagringen er, i så fall slås batteriet automatisk av når batterispenningen er for lav på grunn av den lave batterispenningen. Utladningsdybden er relativt dyp. 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. Ikke tvunget, la vanligvis ikke UPS-strømmen har virket før batterispenningen er for lav og den automatiske avstengningen avsluttes.

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". Dette er fordi denne laderen vil føre til at batteriet er i den harde ladetilstanden "øyeblikkelig overløpslading" og "øyeblikkelig forbigående lading.

Denne tilstanden vil gjøre batteriet sterkt redusert, og batteriet vil bli skrotet når det er alvorlig. 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. Selvfølgelig er det best å bruke en lader som har både konstant strøm, og konstant trykk.

5. Ensure that the capacity of the power supply ambient temperature battery is closely related to the ambient temperature. Generelt er ytelsesparametrene til batteriet kalibrert ved romtemperatur for 20 ° C, og når temperaturen er mindre enn 20 ° C, vil strømlagringskapasiteten reduseres, mens temperaturen er høyere enn 20 ° C, den er tilgjengelig Kapasiteten som brukes vil øke litt.

Ulike modeller av forskjellige modeller av forskjellige modeller er forskjellige fra graden av temperatur. I følge statistikk, når ved -20 ° C, kan batteriet bare nå rundt 60% av den nominelle kapasiteten. Effekten av synlig temperatur kan ikke ignoreres.
