Description

Anti-vibration device for control panel of electric Dower}

The present invention relates to an anti-vibration switch for a switchgear installed at the bottom of the switchgear to prevent damage caused by vibration. More specifically, the present invention relates to an anti-vibration rubber in the center between two vibration-damp plates connected up and down by a plurality of circular-shaped dust-proof wires. The present invention relates to a dustproof outlet for a switchgear, which is provided with a cylindrical leveler, and makes it possible to exhibit a dustproof function more effectively by stably supporting the switchgear at a constant height, by varying the bearing capacity of the levelers installed in each dustproof device.

In general, electrical facilities such as buildings and factories have a large amount of demand power, so they receive 22,900V of high voltage from the power company and step down to the commercial voltage of 220V or 380V.

As described above, the apparatus necessary for the function of transforming the high voltage into the commercial voltage is a switchgear. The switchgear consists of a power supply facility receiving high voltage from the substation, a substation facility for stepping down the high voltage supplied from the substation to a commercial voltage, and a power distribution facility for supplying the stepped commercial voltage safely and efficiently. Will be supplied.

The switchgear having such a configuration has a predetermined volume and is connected between the inlet port to which electric power is supplied from the distribution line inside the enclosure having the door, the automatic section switch connected in series to the downstream of the inlet port, and the downstream section of the automatic section switch unit and the ground. A power fuse for protecting the transformer current transformer connected to the downstream of the lightning arrester, automatic section switchgear, a transformer for transformer for power supply connected to the downstream of the power fuse for transformer transformer protection, and a transformer for transformer for power supply Downstream of the integrated power meter and transformer transformer for power supply and supply, a transformer whose primary side is connected in series, a parking short circuit connected to the secondary side of the transformer, and a plurality of wirings connected to the downstream of the parking short circuit and cut off each load if necessary. The breaker is installed.

The switchgear is fixedly installed as a bolt through a floor angle and a pillar angle assembled by anchor bolts on a concrete floor inside or outside a building.Today, a seismic design is applied to a switchgear to prevent damage caused by earthquakes. It is becoming.

That is, it is designed to have a seismic function by installing a plurality of anti-vibration openings composed of two anti-vibration plates spaced up and down by inserting a plurality of anti-vibration wires circularly inserted between the bottom angle and the bottom installed in the bottom of the switchboard. have.

Therefore, even if vibrations are generated from the ground due to an earthquake or the like, the vibrations are canceled by the anti-vibration wires, thereby minimizing the vibrations transmitted to the switchboard, thereby preventing damages such as leakage and fire due to the vibrations.

However, even if the dust-proof wires constituting each of the dustproof ports installed at the bottom of the switchboard are manufactured to have the same bearing capacity in the design process, the load applied at each bottom of the switchboard is not constant, so the load that each dustproof port bears There was a problem that the distance between the two vibration barriers of each of the dust barrier is not constant.

However, even if each of the vibration isolation holes are designed to have a bearing capacity for the non-uniform load in consideration of the uneven load at each bottom of the switchgear, an error in the bearing force occurs during the manufacturing process, so the gap between the two vibration isolation plates is not constant. There was still.

Therefore, the conventional vibration isolator can not support each bottom of the switchgear at a constant height not only can not support the switchgear stably, but also resulted in the lung can not properly exhibit the dust-proof function.

The present invention has been invented to solve the above problems, and each of the dustproof ports supporting the switchboard supports the switchboard at a constant height irrespective of the uneven load exerted at the bottom of the switchboard at a stable height. In order to support and to effectively exhibit the anti-vibration function, a cylindrical leveler made of anti-vibration rubber is vertically installed between the anti-vibration diaphragms. It is an object of the present invention to provide a dustproof switchboard for a switchgear that can be controlled to be equally spaced apart from the vibration damper.

The dustproof sphere for the switchgear of the present invention has an effect of supporting the switchgear at a constant height to exhibit a dustproof function, thereby more stably supporting the switchgear to exhibit the dustproof function more effectively.

3 is a cross-sectional view taken along the line “AA” of FIG. 2.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the vibration switchboard 100 of the present invention, a plurality of dustproof wires 1 having a circular shape are installed so as to be spaced apart from each other at a predetermined interval by two dustproof plates 2 and 3 spaced apart at predetermined intervals. The upper dustproof plate 2 is fixed to the bottom of the switchgear (D) and the lower dustproof plate (3) is fixed to the bottom (F) in the vibration switch for the switchgear for protecting the switchgear (D) from vibration, the dust-proof Insertion holes 4 and 5 are respectively formed at the center bottom of the diaphragm 2 and at the center upper portion of the vibration isolation plate 3, and the vibration isolation plates 2 and 3 are provided through the insertion holes 4 and 5, respectively. Between the) is characterized in that the cylindrical leveler 6 made of anti-vibration rubber is vertically installed.

The leveler 6 is a variation of the load applied at each bottom of the switchgear (D) so that the interval between the vibration isolation plates (2) (3) of each of the dustproof openings 100 installed at each bottom of the switchgear (D) is constant. In consideration of the variation in the bearing capacity of the anti-vibration wire 1 supporting each bottom of the power distribution panel D, the dust-proofing force is different so that the anti-vibration wire 1 of each of the dustproof ports 100 supports the switchboard D at the same height. It is made of rubber.

In the drawing, reference numeral 7 denotes a fixing bolt 7 for fixing the anti-vibration wire 1 to the anti-vibration plate 2 and 3, and 8 and 9 show the anti-vibration plate 2 and 3 to the floor F and the switchboard. Bolt holes (8) and (9) through which anchor bolts fixed in (D) pass.

As shown in FIG. 4, the dustproof opening 100 for the switchboard of the present invention configured as described above is installed at each bottom of the switchboard D to safely protect the switchboard D from vibrations caused by an earthquake, such as a short circuit and a short circuit. It is a device to prevent an accident such as fire.

In particular, the present invention supports each bottom of the switchboard D at a constant height irrespective of the deviation of the load applied to the bottoms of the switchboard D and the load supporting the bottom of the switchboard D. It is a big feature.

As shown in FIGS. 1 to 3, the cylindrical leveler 6 made of the anti-vibration rubber is vertically disposed to easily adjust the supporting force for supporting the switchboard D between the two anti-vibration plates 2 and 3. It is achieved by standing structure.

That is, the vibration damping plate 2 of all the dustproof outlets 100 installed in the switchgear D by offsetting the deviation of the load applied to each bottom of the switchgear D and the load supporting the bottom of the switchgear D. It is by the structure which made all the spaces of (3) constant.

Therefore, when the dustproof ports 100 are respectively provided at the bottoms of the switchgear D, the dustproof wire 1 of each of the dustproof ports 100 is connected to the bottom of the switchgear D. If the distance between the vibration isolation plates 2 and 3 of each vibration isolation device 100 is not the same due to the deviation in the supporting force for supporting each bottom, the type of dustproof rubber constituting the leveler 6 may be differently applied. Each deviation can be eliminated.

For example, when the distance between the vibration isolation plates 2 and 3 of one of the dust isolation spheres 100 is smaller than the distance between the vibration isolation plates 2 and 3 of the other vibration isolation spheres 100, the one dust protection sphere ( What is necessary is just to select and install the leveler 6 applied to 100 higher than the leveler 6 installed in the other dustproof opening 100.

When the distance between the vibration isolation plates 2 and 3 of the one vibration isolation device 100 is greater than the distance between the vibration isolation plates 2 and 3 of the other vibration isolation devices 100, the one of the vibration isolation plates 100 is provided. What is necessary is just to select and install the applied leveler 6 as having a lower support force than the leveler 6 installed in the other dustproof outlet 100.

That is, when the interval between the vibration isolation plates 2 and 3 of each of the dustproof openings 100 is not constant due to the above-described deviation, if the leveler 6 having a supporting force corresponding to the non-uniform interval is selected and installed, do.

Accordingly, the present invention is able to support all the same height at each bottom of the switchboard (D), so that the dustproof function can be properly exhibited while supporting the switchboard (D) more stably.

Therefore, due to the internal structure of the switchgear (D) and the manufacturing problems of the anti-vibration opening (100), it is not possible to support each bottom of the switchgear (D) to a certain height to completely solve the conventional problem that could not properly exhibit the dust-proof function. It becomes possible.
