UPS uninterruptible power supply mode and UPS power supply principle. UPS is not a power supply, it does not rely on the conversion of energy form to supply electricity, it is only a supply of two power supply uninterrupted mutual switching opportunity, this is the important design idea of UPS uninterrupted power supply. The UPS power supply consists of batteries, inverters, rectifiers, and static switches.
A large UPS should provide intelligent battery management, periodic battery self-check, and automatic battery maintenance. Charge/float charge automatic conversion, automatic temperature compensation and other functions to extend battery life.
UPS uninterruptible power supply skills:
First, the current extension of the UPS uninterruptible power supply system is divided into two kinds of important power supply time, external large capacity battery pack, according to the required power supply time, external corresponding capacity battery pack. Choose a UPS power system with a larger capacity to reduce maintenance costs. Once the load device expansion is encountered, the larger capacity of the continuous power system, still can operate immediately.
Second, in the UPS uninterruptible power system switch, also to clear the relevant skills. When starting up for the first time, the switch should be closed in the corresponding sequence. Energy storage battery switch, automatic bypass switch, and output switch are successively set to “ON” state. Press the On button on the UPS startup panel. The UPS power systems start one by one, and the Inverter indicator is on. After a 1-minute delay, the Bypass indicator is off.
The UPS battery pack is mainly composed of lithium battery 18650.
