Causes of UPS power cannot be used normally, UPS power maintenance precautions. The UPS power supply is not very durable in use, as well as some small faults like other devices. Once the UPS power is faulty, it is necessary to calm down the problem, but also to accumulate more solve problems in us.
Relevant experience, so that the technical staff check the problem better maintenance. The UPS power supply cannot be used. The UPS power supply system should supply uninterrupted power supply for the load.
When purchasing the UPS uninterrupted power supply, it is necessary to understand the environment that the UPS uninterruptible power supply cannot be used in the application and the load device that cannot be used. Damage to the UPS power supply. In the process of using the UPS power supply, we can prevent malfunctions.
Many people don't understand how to solve it after the failure. Here, our Xiaobian reminds everyone that most faults can be solved by us. Share common reasons for everyone.
1. Its important cause and possible damage is similar to the high pressure tip pulse, but there will be differences in the solution. 2, the UPS power supply voltage drop voltage is trapped by the market voltage effective value of 80% to 85% of the rated value, and the duration reaches one to several cycles.
Large-scale equipment boot, large motor start, or large power transformer access can cause this problem. 3, the UPS power supply surge voltage output voltage effective value is higher than the rated value of 110%, and the duration reaches one or several cycles. The surge is important because the large electrical equipment connected to the grid is turned off, and the power grid will occur due to sudden unloading.
4, the UPS power supply continues low voltage continuous low voltage indicates that the market voltage variable value is below the rated value, and lasts for a long time. Its causes include: large equipment start and application, main power line switching, launch large motor, line overload. If your market has a similar problem, it is recommended that you ask the power sector to measure the frequency, waveforms, and voltage of the grid to confirm whether the market has the above problems.
UPS Power Supply Precautions ● Before you turn on, you must turn off all loads collected by the UPS. Be sure to open the UPS in the case of the main market, after the UPS is supplied, let the load electricity. ● If the UPS power supply works in the current situation, it is recommended to unplug the AC power supply every three months, make the inverter work, let the battery pack discharge until the alarm signal is shortened, and then turn on the external power supply.
● The actual load of the UPS power supply is subject to 70% of its power. If the actual power is 700W, the power should be selected from the UPS of 1000W. Note that the load cannot be a controllable silicon rectifier circuit and a larger inductor circuit, otherwise danger occurs.
● Newly purchased UPS power should be charged and discharge, which is conducive to extending the service life of the UPS power battery. General pressure charging. UPS Power Supply Precautions How to use, repair and maintain large UPS power supplies, understand and master its technical performance, operation characteristics, daily maintenance, to ensure that the UPS power supply is stable and reliable, extend the service life of the UPS power supply, and play the effective use of UPS power supply, It is an indispensable job in our daily work.
1. UPS power supply In normal use, the maintenance work is very small, it is important to dust and regular dust removal. In particular, there is more gaseous gases in the air, and the wind opportunities in the air will deposit the dust in the machine.
When the air is wet, the host control disorder causes the host's working abnormality, and does not have an accurate alarm, a lot Dust will also cause the device to heat dissipation. UPS power is generally cleaned once a quarter. Secondly, when dust removal, check the connections and coupons have no looseness and contact.
2, although the energy storage UPS battery pack is currently maintenance-free battery, but this is exempt from previous measurement, ratio, and add distilled water on time. However, the external cause of work is not changed, and the influence of abnormal operating conditions has not changed. This part of the maintenance and maintenance work is still very important.
The large number of maintenance and maintenance work in the UPS power system is important in the battery part. 3. When the UPS battery system fails, it should be identified first.
Is it a load or a UPS power system; is a host or a battery pack. Although the UPS host has failed self-inspection function, it is opposite, it is very convenient to replace the accessories, but to repair the fault point, still need to do a lot of analysis, testing work. In addition, if the self-test portion has failed, the displayed fault content may be wrong.
4. The failure of breakdown, breaking insurance or burnt devices, must identify the cause and troubleshoot, otherwise the same fault will occur after connecting. 5.
When performing UPS power maintenance, you must pay attention to safety. When processing a power supply, it may be afraid that a small operating mistake will also cause serious injury. Therefore, when processing the UPS power supply, you should follow the safety rules: including compliance with equipment manufacturers, pay attention to the special details and standard safety guidelines.
Lithium-ion battery UPS uninterruptible power supply solution focus reliable, efficient, simple design concept Difficult to monitor the shortcomings, supply appropriate power supply solutions to customers, easy to deal with grid problems. .
