PURPOSE:To perform inspection, adjustment, sampling, and exchange on an inverter and charger without stopping power supply to a load while commercial power supply is made by constituting an uninterruptible power supply of a transformer unit, inverter charging unit, and battery unit in a divided state. CONSTITUTION:The title uninterruptible power supply is constituted of a transformer unit A, inverter charging unit B, and battery unit C in a divided state. At the time of performing inspections or switching on a charger 11 and inverter 12, the units A, B, and C are separated from each other by disconnecting connecting sections between each terminal and commercial power supply is connected to a load. Therefore, maintenance, inspection, adjustment, sampling, and exchange can be performed on the charger 11, inverter 12, and battery 21 under a condition where the power supply is made to the load (uninterruptible power condition). |
