Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a large UPS complete power failure prompting device. Background Art

[0002] UPS stands for Uninterruptible Power Supply, which is an uninterruptible power supply with an energy storage device. It is mainly used to provide uninterruptible power supply to some equipment that has high requirements for power supply stability.

[0003] The existing technology has the following shortcomings:

[0004] When the UPS is powered off for maintenance, it is usually necessary to open the cover around the switch for internal inspection. However, it is very easy to touch the internal input copper busbar during the disassembly process. Once the circuit breaker of the input distribution cabinet upstream of the UPS is operated incorrectly, that is, the circuit breaker is not disconnected, the input copper busbar inside the UPS is energized. If the cover touches the input copper busbar or the screws fall onto the input copper busbar during the disassembly process, a short circuit accident is very likely to occur, endangering the safety of personnel and causing damage to the equipment.

The other end of the voltage sampling board 6 is electrically connected to the alarm device 7. When in use, the voltages at the main input terminal 10, the bypass input terminal 11 and the output terminal 13 are sampled respectively through the voltage sampling board 6. When the voltages at the sampling points are all less than 10V at the main input terminal, it is judged that the power is completely cut off inside UPS1.

If the indicator light of the alarm device 7 is always on, the power inside UPS1 has not been completely cut off. If the indicator light is off, the power inside UPS1 has been completely cut off. Therefore, a prompt is given during the maintenance and inspection of UPS1 to prevent possible short-circuit accidents and avoid huge losses to the data center.
