Embodiment 1

[0006] Embodiment one: if Figure 1-2 As shown, the mains input sends power to the UPC output terminal and transformer through voltage detection and switching, and the transformer charges the battery through rectification.

[0007] A detection circuit and a discharge circuit are connected at both ends of the battery, whether the discharge circuit is connected or not is controlled by K3, K3 is controlled by PLC, and PLC colleagues control the display device. When there is no voltage in the mains, the storage battery becomes alternating current through the inverter bridge, and is boosted by a transformer and sent to the output terminal of the UPS.

Abstract

A UPS accumulator online testing and display method is characterized in that mounting a voltage testing unit at the anode and the cathode of the UPS accumulator respectively; disconnecting the charging circuit when the accumulator is filled with charges, testing voltages at the two ends of the accumulator, and storing the voltages in a storage unit of a programmable logic controller (PLC); connecting the accumulator discharging circuit rapidly, testing the voltages at the two ends of the accumulator immediately, and storing the voltages in the storage unit of the PLC; comparing the measured values of the two times, determining whether the accumulator is good in state, up to standard and damaged according to criteria stored in the PLC, and displaying the result through a displayer. A UPS accumulator online testing and display device comprises a UPS circuit, the voltage testing units, the PLC and a display circuit. The method is simple and reliable, has few effects on the operation of the UPS by the aid of online work and is of great application value for the improvement of the reliability and cost performance of the UPS.

Description

technical field [0001] The invention relates to a UPS storage battery online detection and display method and device ， Suitable for UPS and devices with inverter function using batteries. Background technique [0002] Existing UPS devices only have the battery charging function and uninterrupted power supply capability. When the mains power is normal, the battery is charged and cut off after charging. After the mains power disappears, the battery is immediately started to invert to the corresponding voltage of the mains to restore power to the user. However, it is impossible to judge the performance of the important device battery without testing, which seriously affects the reliability and safety of the product. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the object of the present invention is to provide a UPS battery online detection and display method and device, through which various statuses of the UPS battery c...
