Abstract

PURPOSE:To facilitate an inspection, a maintenance and a repair by dividing the interior of a casing into two segments, containing a flywheel unit in one space, and containing a power source in the other space, thereby effectively utilizing the spaces. CONSTITUTION:A flywheel power source 20 has a casing 21 made of substantially regular quadrangle box. The casing 21 is divided therein by a rack plate 22 into upper and lower portions. A flywheel unit 30 is disposed on the bottom plate of the lower side of the plate 22, and a power source 40 is disposed on the plate 22. A flywheel unit 30 and the power source 40 are mounted or removed through the hole 23 of the casing 21.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a flywheel power supply device that compensates for power outages using a flywheel device that rotates at high speed.

[Prior art]

1 and 2 are simplified configuration diagrams showing an example of a conventional flywheel power supply device. In the figures, F is a power supply main body, and this power supply main body F includes a high frequency inverter 1, a converter 2. Changeover switch 3. It has a main circuit converter 4.5. R is a flywheel device;
This flywheel device R is composed of a motor/generator section and a flywheel.

This flywheel power supply device normally supplies constant-voltage, constant-frequency alternating current power from an external power source 8 to a load 9 via a fault selector switch 6 from a main circuit consisting of a main circuit converter 4 and a main circuit converter 5. . At this time, the selector switch 3 of the power failure compensation device consisting of the high frequency inverter 1, flywheel device R and converter 2 is open.
A flywheel built into the flywheel device R stores energy through high-speed rotation by the high-frequency inverter 1.

When an abnormality occurs in the external power supply 8 due to a power outage or the like, the changeover switch 3 is closed, and the generator generates electricity by inertial rotation of the flywheel of the flywheel device R. This AC power is converted to DC power by converter 2,
It is supplied to the load 9 via the main circuit inverter 5 and the fault changeover switch 6.

Note that the failure changeover switch 6 and the failure changeover switch 7 are used to directly supply power from the external power supply 8 to the load 9 when the flywheel power supply device fails. Further, the power supply device F includes a high frequency inverter 1. Input processing means consisting of main circuit converter 4; Changeover switch 3, main circuit converter 5, failure changeover switch 6.
and an output processing means 11 consisting of 7.

However, according to such a conventional flywheel power supply device, the power supply device F and the flywheel device R are
As shown in Figure 1, it is a separate unit, so the power supply F
However, it is necessary to secure a space for installing the flywheel device R and a space for installing the flywheel device R, which has the disadvantage that a large installation space must be prepared. Also, since the two are separate units, inspection is required in addition to installation.

It also has the disadvantage of being troublesome to handle maintenance, repairs, etc.

[Summary of the invention]

An object of the present invention is to solve the above-mentioned drawbacks by dividing the inside of a casing housing a flywheel power supply into two parts, storing the flywheel in one space, and storing the power supply in the other space. This will be explained in detail below using examples.

[Embodiments of the invention]

FIG. 3 and FIG. 4 are simplified configuration diagrams showing an embodiment of the flywheel power supply device according to the present invention, and in the same figure,
The flywheel power supply device 2o includes a casing 21 made of a substantially square columnar box, a flywheel device 30 disposed on the lower bottom plate of a shelf board 22 that divides the inside of the casing 21 into upper and lower parts, and the above-mentioned flywheel device 30. Shelf board 2 of casing 21
2, and a power supply device 4o disposed on the top of the power supply device 4o.

The casing 21 is surrounded on three sides by side walls and has an opening 23 on one side, and this opening 23 allows installation of the flywheel device 30, power supply device 40, and wiring (not shown) that are housed inside. Alternatively, removal is performed. This opening 23 is provided with an opening/closing lid 24 attached to one side end by a hinge 25 so as to be openable/closable, and a handle 26 is attached to this opening/closing lid 24. As shown in FIG. 4, a flywheel device 30 is housed in the space below the shelf board 22 of the casing 21. Bearing 32 installed in medium heat
, 33 via a bearing 34 via a shaft 35, and an electric motor that provides rotational force to the flywheel 36 and converts the inertial rotational force of the flywheel 36 into electrical energy in the event of a power outage. It is composed of a power generation section 37. Inside the power supply device 40, there is an input processing means for supplying input from the power supply to the flywheel device 30, and an output processing means for converting the electrical energy obtained by the rotational force of the flywheel into a waveform suitable for output. It has

According to the above configuration, the flywheel device 30 and the power supply device 40, which are assembled separately, are connected to the power supply side and the load side, respectively, and are arranged on the bottom plate and shelf board of the casing 2. By opening and closing the lid,
Installation of the flywheel power supply device 20 is completed. By housing the flywheel device 30 and the power supply device 40 integrally in such a casing 21, it can be installed in a narrow space, and the flywheel power supply device 20 can be inspected, repaired, and not only installed. Replacement etc. can also be done easily.

In the above embodiment, the ordinary flywheel device 30 was described as being housed, but the present invention is not limited to this, and as shown in FIG. Alternatively, the power supply device 52 may be stored on the side and placed on the shelf board 53. Also,
The opening/closing lid is not a one-piece type, but a double opening/closing lid 54. ．． 5

You may also place .

〔Effect of the invention〕

As explained above, according to the flywheel power supply device according to the present invention, the casing, the flywheel device,
The inside of the casing of a flywheel power supply device equipped with a power supply device is divided, and the flywheel device is housed in one space, and the power supply device is housed in the other space. The flywheel power supply device can be installed using a more efficient space than in the past, where it was separate. Also, since the flywheel device and power supply device are housed in one casing, it is possible to inspect the entire flywheel power supply device.
It is possible to easily perform system repairs, device replacement, etc., and to improve work efficiency.
