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. The following detailed description: 1. Regular inspection periodically check the end voltage and internal resistance of each unit battery periodically.

For a 12V unit battery, if the end voltage difference between the unit cells is found to be more than 0.4V or more than 80m or more, the unit cell should be balanced to restore the internal resistance of the battery. Мөн нэгж үүр бүрийн хоорондох төгсгөлийн хүчдэлийг арилгана.

The charging voltage takes 13.5 ~ 13.8V when charging.

The vast majority of batteries that have been balanced charging can return its internal resistance to 30m or less. During operation, the UPS power supply is eliminated due to the above-described imbalance of each unit battery characteristics, which is not possible to rely on the charging circuit inside the UPS power supply, so a significantly unbearable battery has undergone such characteristics. Групп, хэрэв офлайныг цаг тухайд нь цэнэглээгүй бол түүний тэгш бус байдал улам бүр ноцтой болно.

2. Re-floating the UPS power stop for more than 10 days, before rebooting, the UPS power supply should be launched without the load to re-use the charging sub-product electrical circuit in the machine to recharge the battery to the battery. run.

The UPS power supply is in a floating state without discharge, which is equivalent to the storage of storage. If this state has been too long, the battery has not been scrapped due to the storage of too long, it is important that the battery internal resistance is increased, and the internal resistance can reach a few times. We found that after 2 months of room temperature, it is stored for 1 month, and the capacity of the battery is about 97% of its rated value.

If it is not used for 6 months, its use capacity becomes 80% of the rated capacity. If the storage temperature is increased, its use capacity will decrease. It is therefore recommended that the user is best to unplug the mains input every 20c, so that the UPS power supply is operated by the battery supply energy to the inverter.

Гэсэн хэдий ч, энэ үйл ажиллагаа нь хэтэрхий урт байх ёсгүй бөгөөд ачааллын 30 орчим хувь нь нэрлэсэн гарцын 30 орчим хувийг эзэлдэг тул цэнэггүй болгож болно. 3. Reduce the service life of deep discharge electricity is closely related to the depth of it is discharged.

The lighter the load of the UPS power supply, the larger the battery supply of the battery, the larger the amount of capacity of the battery and its rated capacity, in which case the battery is discharged when the UPS power is automatically turned off due to the low low battery voltage. Deep is relatively deep. 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, notify the user to supply energy by the battery. Тэр дохиоллын дууг яаралтай сонссон бол эрчим хүчний хангамж нь аль хэдийн гүнд байгаа бөгөөд яаралтай тусламжийн эмчилгээг яаралтай хийх ёстой бөгөөд UPS цахилгаан хангамжийг хаах хэрэгтэй. Албадан биш, ерөнхийдөө батерейны хүчдэл хэт бага болж, автомат унтрах хүртэл UPS-ийг ажиллуулж болохгүй.

4. Using the high peak charging of the power supply About UPS power supply for a long time in the market, low-voltage power supply or frequently-powered power, to prevent the battery from being damaged by the long-term charging, it should make full use of the power supply peak (such as late night) to charge the battery Ensure that the battery has sufficient charging time after each discharge. When the battery is depressed, it is more than 90% of the rated capacity to at least 10 to 12 h.

Note that the charger is used for the UPS power supply-free seal battery that cannot be charged with a controlled silicon-type fast charger. This is because this charger can cause the battery while being in the harsh charging state of the transient overflow and instantaneous transient charging. Энэ байдал нь батерейг их хэмжээгээр бууруулж, батарейг хүнд үед нь устгана.

When using the UPS power supply of the constant voltage cut-off charging loop, be careful not to transfer the battery voltage too low protection work points, otherwise, over-flow charge can be easily charged in the initial stage of charging. Мэдээжийн хэрэг, тогтмол гүйдэл, тогтмол даралттай цэнэглэгч ашиглах нь хамгийн сайн арга юм. 5.

Цахилгаан хангамжийн температурын батерейны хүчин чадал нь орчны температуртай нягт холбоотой эсэхийг шалгаарай. In general, the performance parameters of the battery are calibrated at room temperature for 20 ¡ã C, and when the temperature is less than 20 ¡ã C, the power storage capacity will be reduced, while the temperature is higher than 20 ¡ã C, it is available The capacity used will increase slightly. Янз бүрийн загваруудын янз бүрийн загварууд нь температурын зэргээс ялгаатай байдаг.

According to statistics, when at -20 ¡ã C, the battery can only reach around 60% of the nominal capacity. Үзэгдэх температурын нөлөөллийг үл тоомсорлож болохгүй. Мэдээжийн хэрэг, батерейны ашиглалтын хугацааг уртасгахын тулд зөвхөн засвар үйлчилгээнд анхаарлаа хандуулаад зогсохгүй ачааллын шинж чанар (эсэргүүцэл, индукц, багтаамж) болон хэмжээг сонгохдоо анхаарч үзээрэй.

Don't make the battery last over light load operation, so as not to avoid the UPS battery discharge current, the battery is scrap.
