With the development of the economy of our country, UPS power supply has been widely used in various fields. Parallel operation can guarantee the operation of electric control equipment to a certain extent, and also can have enough time to deal with the possible emergency. The ups power supply manufacturers mainly analyze the parallel operation and maintenance of the UPS power supply, aiming at better application of the UPS power supply.
An introduction
UPS power supply is an important guarantee to ensure electronic equipment continue to work, and is mainly used among complex engineering projects in our country, including water conservancy engineering, thermal power engineering and aeronautical engineering. The UPS power supply does not need to be replaced for a long time. Therefore, users often neglect the overhaul and maintenance of the UPS power supply.
2 Operation requirements and working principles of the UPS power system
(I) Specific requirements for the operation of the UPS uninterruptible power system
In order to achieve normal operation of UPS power supply, it is necessary to run in parallel. In the specific process of operation, it is also necessary to provide a certain float for the battery to charge, to provide a stable AC output for the whole system, and then realize the constant power of the whole system, which is the most important role of UPS power supply. When the UPS power supply is carried out, even if the whole system is in a state of power failure, it can also change a steady alternating current to continue the power supply, and this alternating current can last for more than 10 hours. By using such a power source as an important device for dealing with daily incidents, it is very necessary to provide a certain amount of respite time for reporting and reduce losses and problems that may occur.
(II) The operating principle of UPS uninterruptible power system
The operating principle of UPS power supply is to store electric energy in the battery of the unit, and then continue to supply power after the mains interruption, so as to reduce the loss caused by the power failure of the unit. For the electrical energy stored in the unit, it is generally in the form of direct current, but the UPS power supply because the inverter is generally in the form of alternating current, so there is a converter in the UPS power supply, convenient current conversion and adaptation.
