PURPOSE:To enable a non-power-failure power supply device UPS to be inflammable by housing parts into individual containers by separating them into those with a semi-permanent and non-permanent lives and then by circulating an inflammable gas through a bypass pipe, CONSTITUTION:A rectifying room 1A, an inverter room 2A, an AC switch room 3A, a battery room 44, a control device/communication device room 5A, a rectifier transformer room 71A, an inverter transformer room 72A etc., are provided and then they are stored separately after they are divided into those with a semi-permanent life such as a rectifier transformer and those with a non-permanent life such as a rectifier which needs to be replaced periodically. Each room is connected by bypasses 10A, 10B, and 10C for circulating an inflammable gas, thus achieving inflammability. Air is circulated through a fan FA of a cooling pipe 9 for cooling the inflammable gas. Pipes of a flange FL are rigidly connected to prevent the inflammable gas from being leaked when replacing parts. |
