2. Description of the Related Art FIG. 4 is a right side view of a conventional example, and FIG. 5 is a front view of FIG. In the figure, this uninterruptible power supply system includes a main circuit unit 2 and a cooling fan unit 3 in a box body 1.
, Battery unit 4 and input / output transformer unit 5
And a door 7 that can be opened and closed by a hinge 6 is provided on the front surface of the box body 1. The cooling fan unit 3 is arranged behind the main circuit unit 2, the small door 8 on the ceiling surface of the box 1 can be opened and pulled out upward, and the control device 9 such as a printed circuit board is provided on the front surface of the main circuit unit 2. Be attached to. A monitor panel 10 for operation is provided on the upper surface of the door 7 so that it can be seen easily, and the battery unit 4 and the input / output transformer unit 5 are arranged under the box 1 in order to stabilize the center of gravity of the device.

[0003]

In the above-described conventional example, as the height of the cooling fan unit 3 increases, it becomes more difficult for a person to reach out from the front surface of the uninterruptible power supply unit to pull out the cooling fan unit 3. Instead, a person must turn to the side and pull it out. This tendency becomes stronger as the uninterruptible power supply has a larger capacity. In the space to the left and right of the uninterruptible power supply, computer-related equipment is arranged, and these equipments must be moved each time for maintenance of the uninterruptible power supply. The control device 9 is located immediately before the main circuit unit 2 and inhibits cooling of the main circuit unit 2.

SUMMARY OF THE INVENTION An object of the present invention is to provide an uninterruptible power supply in which a person can easily take out a cooling fan unit that is frequently maintained from the front even if the uninterruptible power supply becomes large.

[0005]

SUMMARY OF THE INVENTION An uninterruptible power supply unit of the present invention has a main circuit unit, a cooling fan unit, a battery unit and an input / output transformer unit housed in a box body, and is provided on the front surface of the box body. In an uninterruptible power supply device having a hinged door that can be opened and closed, the cooling fan unit is detachably arranged between the main circuit unit and the door. At this time, a flat plate-shaped control device which can be opened and closed by a hinge is arranged between the cooling fan unit and the door.

[0006]

Operation Referring to FIG. With the main circuit unit 2a installed in the box 1 in the installed state, the cooling fan unit 3a, which is frequently maintained, can be easily taken out from the front by opening the door 7. At this time, the control device 9a is on the windward side of the cooling fan unit 3a and is on the leeward side of the main circuit unit 2
It does not hinder the cooling of a.

1 is a right side view of the embodiment, FIG. 2 is a front view of FIG. 1, and FIG. 3 is a plan view of FIG. Those given the same reference numerals as in the conventional example have approximately the same function, and duplicate explanation may be omitted. In the figure, this uninterruptible power supply device includes a main circuit unit 2a, a cooling fan unit 3a, and a box 1 in a box 1.
A door 7 which houses the battery unit 4 and the input / output transformer unit 5 and which can be opened and closed laterally with a hinge 6 on the front surface of the box body 1.
Is provided and configured. The cooling fan unit 3a is detachably disposed obliquely upward between the main circuit unit 2a and the door 7, and the plate-shaped control device 9a has a hinge (not shown) between the cooling fan unit 3a and the door 7 on the front surface. It can be attached to open and close freely. In order to make the cooling fan unit 3a detachable, for example, the lower part of the cooling fan unit 3a is a locking set 21 including a hook 21a and a rod 21b,
The upper part is attached to the box 1 with screws 22. As shown in the drawing, the rod 21b fixed to the box 1 is attached to the cooling fan unit 3
You may change to the a side. A monitor panel 10 for operation is provided on the upper surface of the door 7 so that it can be seen easily, and the battery unit 4 and the input / output transformer unit 5 are arranged under the box 1 in order to stabilize the center of gravity of the device.

According to such a structure, with the main circuit unit 2a installed in the box body 1, the cooling fan unit 3a, which is frequently maintained, can be easily taken out by a person from the front by opening the door 7. Since there is no need for people to go to the side of the power failure power supply, the layout of related equipment is compact and maintenance is quick. Further, the control device 9a is above the cooling fan unit 3a, and the main circuit unit 2a is below the cooling fan unit 3a, so that the cooling of the main circuit unit 2a is not hindered.

[0009]

According to the uninterruptible power supply of the present invention, the cooling fan unit, which is frequently maintained, can be opened by the front of the cooling fan unit, which is frequently maintained, while the main circuit unit is installed in the box in the installed state. Since it is possible to take it out and there is no need for people to go to the side of the uninterruptible power supply, the arrangement of related equipment is compact and maintenance is quick. Further, the control device is on the windward side of the cooling fan unit and does not hinder the cooling of the main circuit unit.
