t1, firstly, the UPS (1) is connected to a power supply system of the frequency converter, and when the power supply system generates a power interference phenomenon, the UPS (1) can provide a backup power supply for the frequency converter, so that the power interference phenomenon is avoided from being generated continuously;
t2, when the power supply input of the UPS (1) is normal, the UPS (1) supplies the power to the connected equipment after stabilizing the voltage, and simultaneously charges the storage battery (4) on the base (3); when the power supply is insufficient, the storage battery (4) supplies power to the UPS (1), so that the UPS (1) keeps normal work, the voltage is ensured to be normal, and the generation of a power-shaking phenomenon is avoided;
t3, when the operating temperature of the storage battery (4) is too high, the heat dissipation mechanism (9) can dissipate heat for the storage battery (4);
t4, when the storage battery (4) is overhauled, the storage battery (4) can be pulled out from the storage battery box (2) for overhauling by releasing the limit of the limit mechanism (6), and the overhauling is very convenient.
