Description

Technical Field

[0001] This patent relates to the field of power supply technology, specifically an online replaceable uninterruptible output power supply. Background Art

[0002] An uninterruptible power supply is a constant voltage and frequency uninterruptible power supply that contains an energy storage device and has an inverter as its main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS stabilizes the mains and supplies it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; when the mains power is interrupted (power outage due to an accident), the UPS immediately uses the power of the battery inside the machine to continue to supply 220V AC to the load through an inverter conversion method, so that the load maintains normal operation and protects the load software and hardware from damage. UPS equipment usually provides protection against both excessive voltage and too low voltage.

[0003] Currently, a mains plug is plugged into the back of the power supply body, but there is no sealing structure between the mains plug and the power supply body. Over time, dust and water vapor can easily enter the interface, affecting the electrical connection effect. For this reason, we propose an online replaceable uninterrupted output power supply.
