Basic knowledge of UPS power supply, UPS power maintenance precautions. UPS power supply has become a must-have power supply for companies and families. The UPS power supply is also a device that can continue to supply uninterrupted power supplies to the electricity equipment in the market, to ensure that the equipment can work properly.
If the user does not use and maintain the UPS power supply, it is not only able to effectively use the use of UPS, but it may shorten its service life when severe. Basic knowledge of the UPS power supply 1. Which load is generally strong? General UPS is designed according to the sensitive load, so the inductive load is its own points.
Generally, the capacitors in parallel in parallel in the UPS inverter output, on the other hand, the inductance component in the load. If the load is accommodating, how can the capacitance to cancel the capacitive component with capacitance? The output of the capacitance component can be increased, and the current of these capacitance components must be supplied by the inverter, so that the active components of the inverter output are reduced. Small, so the ability to load is weakened.
2, what is the advantages and disadvantages of the power console and high frequency machine? Work frequency UPS: Dampoint is that the input power factor is low, power consumption, low efficiency, high volume, high price, low reliability; advantage is manufacturing relative Easy, especially if the impact of manual operation is not large, and the consistency is relatively low. High frequency machine UPS: Advantages are high input power factor, small power consumption, high efficiency, high size, light, reliability; but high production means, strict requirements. 3, why UPS capacity is expressed in VA? The unit of powerful power is wat (W), the unit of reactive power is a lack of "var).
The general UPS power supply is used as a power representation. Since the power is included in the power, it is also not able to call the War, which is not called W. Since the power is volts (V) and ampeals.
(A), as determined to be VA. 4. Because the UPS installs lightning protection, it can only make the power-saving lightning protection in the power distribution cabinet, but it is still not possible to omit the lightning protection device.
5. Learn about how the UPS development does this? Understand the direction of the development of UPS uninterruptible power supply to prevent users from being prevented from being eliminated or eliminated immediately, so as not to cause unnecessary losses. At present, UPS has developed to online parallel redundancy modular solution system UPS, please reckonize the modularization, it will replace the application of traditional UPS in data machine room.
6. How long can the UPS battery use? The battery life of the UPS will eventually be exhausted, and it is necessary to replace every 3-5 years. When the battery is about to exhaust, the UPS power will flash red light and issue an alarm to notify the user.
Since the UPS power is important to use a lead-acid battery, we must safe and monitor management. UPS Power Maintenance Precautions ● Backup UPS Power Wan Should not be used on a back-backup UPS power supply on a device-sensitive device that is usually in battery floating state, and the inverter switches to the working state during power failure, and the direct current of the battery is stable. AC output, but this UPS has a problem of switching time, not suitable for device protection for power sensitive devices.
● It is not possible to run the UPS power for a long time to run the UPS power in many people. To give full play to the power of the UPS, you should have the UPS to run in the rated power. This is correct, but if the UPS long-term full-time operation may greatly shorten its service life.
The principle of UPS should be to let the UPS are tryable to use for critical devices, rather than connecting the device that does not have to power the power protection, which can only increase the operational burden of UPS, shorten its service life. ● When the security first is maintained, it 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. ● The ambient temperature is too high, which makes the UPS battery overcharge, the ambient temperature is too low, which will make the UPS battery charge, which will affect the service life of the UPS battery. Therefore, it is generally required that the ambient temperature is about 25 or so, the UPS floating voltage value is also set according to this temperature.
Many UPS maintenance matters are best left to those who are familiar with UPS. Also emphasized, safety is crucial: the risk of voltage in a UPS system may have personal injury, so it is best to hire a professional, not to take risks. Can the UPS can operate normally and have a high level of work quality and the battery pack it is inseparable, while in daily work, the staff should use and carefully maintain the UPS power supply and battery pack.
