In general, a switchboard is a place where machines and protective equipment are installed to distribute down and distribute under high pressure, and the switchboards equipped with these various kinds of electronic components (hereinafter referred to as "electronic components") are installed inside a housing of a hexahedron have.

The above-mentioned switchboard can be classified into a special high-voltage switchboard, a low-voltage switchboard, an MCC, and a distribution board, but the present invention will be generally described as an switchboard.

On the other hand, recent statistics of the Korea Meteorological Administration show that the frequency of earthquakes is increasing, and the frequency of seismic intensity over 5 is also increasing. Accordingly, there have been proposed techniques for preventing the damage caused by an earthquake by applying an earthquake-resistant design structure to the switchboard installed inside the building.

Korean Patent No. 1498270 (registered on Feb. 25, 2015) relates to an "anti-corrosive power distribution board", comprising an upper plate coupled to a lower surface of an electric distribution board and having a flow hole on a central portion thereof, A support block formed between the upper plate and the lower plate and fixed to the upper portion of the lower plate; a plurality of horizontal vibration damping means for vertically connecting the support block and the upper plate to each other; A vertical vibration preventing means provided in a support block groove formed on a central portion of the support block, a ball support base formed on an upper portion of the vertical vibration preventing means and vertically movable with respect to a force acting vertically, A rotating ball rotatably mounted on a ball supporting groove formed in the lower portion of the rotating shaft, Bolt and seismic device comprising a supporting nut which is fastened to the support bolt in the through-state through the flow holes and a distribution board hole presents a technique that is configured to lower.

In the drawings, the same reference numerals are given to the same elements even when they are shown in different drawings. In the drawings, the same reference numerals as used in the accompanying drawings are used to designate the same or similar elements. And detailed description of the configuration will be omitted. Also, directional terms such as "top", "bottom", "front", "back", "front", "forward", "rear", etc. are used in connection with the orientation of the disclosed drawing (s). Since the elements of the embodiments of the present invention can be positioned in various orientations, the directional terminology is used for illustrative purposes, not limitation.

As shown in FIG. 1, the distribution board (anti-high voltage switchboard, low voltage switchboard, MCC panel, and distribution board) according to the preferred embodiment of the present invention includes a switchboard enclosure (100) mounted on an upper surface of the switchboard enclosure (200) and through which the power lead-in wire (110) is passed, and a power supply line And a bottom seismic device 150 mounted on the bottom of the cabinet 200 of the switchboard.

As known in the art, the switchgear housing 200 is formed in a hollow hexahedron shape and has a door on the front surface thereof and a power lead-in line 110 for receiving external power through the upper surface thereof. Further, although a power supply lead line for connecting to the outside through the switchboard enclosure 200 is formed, illustration is omitted in the figure.

The above-mentioned switchboard includes an operating lever for opening and closing a circuit breaker of a main circuit, an electronic switch such as a voltmeter, an ammeter, a power meter, a countermeasure meter, and an ammeter, including an extraordinary high voltage switchboard, a low voltage switchboard, an MCC And the electric component is electrically connected to the power lead line 110 through a conductive part.

The seismic isolation device 100 can prevent vibration transmitted to the cabinet enclosure 200 and prevent damage to the cable tray 120 or the pipe (not shown) in which the power lead line 110 is supported and fixed. . In other words, the power supply line or the power supply line is supported and fixed to the cable tray 120 or the pipe, and is connected to the switchboard housing 200. If vibration occurs in the building due to an earthquake in such a state, the cable tray 120 or the pipe may be damaged or the tray support bar 121 for supporting the cable tray 120 may be damaged, The lead wire is severely flowed. As a result, the power lead-in line to the power lead-out line connected to the switchboard is severely damaged by the contact failure such as short or open with the conductive portion of the switchboard.

Therefore, the seismic isolation system 100 according to the present invention can prevent the cable tray 120 or the pipe from being damaged by allowing the switchboard enclosure 200 and the cable tray 120 or the pipe to independently flow, It is possible to prevent accidents caused by poor contact between the power lead-in line connected to the switchboard or the power lead-out line and the conductive portion of the switchboard.

In addition, the lower seismic equipments 150 absorb or block the vibration transmitted through the building.

1 to 6, the seismic resistance device 100 includes a connection plate 10 mounted at the end of the cable tray 120, and a connection plate 10 spaced apart from the connection plate 10 And a spring member (50) and a support frame (30) installed between the connection plate (10) and the flow plate (20) And a separation frame 40 mounted on a side surface of the frame 200.

The connecting plate 10 is fixed to the end of the cable tray 120 in a plate shape and is provided with a power line penetration hole (not shown) at the center so that the power lead line 110 or the power lead line, 12 are formed.

The flow plate 20 has a disk shape having a predetermined thickness and is disposed at a predetermined spacing from the connection plate 10, and a contact member 60 is provided at an edge thereof.

At this time, it is preferable that the contact member 60 is made of steel and mounted on the edge of the flow plate 20, and is formed to have a transversely triangular structure as shown in FIG. Here, the contact member 60 may be provided along the edge of the flow plate 20 or may be installed along the edge of the flow plate 20 at a predetermined distance. A through hole is formed at the center of the flow plate 20 so that the power lead line 110 or the power lead line passes through the center.

The spring member 50 is installed between the connection plate 10 and the flow plate 20 to absorb or buffer the vibration energy propagated to the cable tray 120 due to the earthquake and transmit the vibration energy to the switchboard housing 200 So that it is possible to prevent deformation and breakage of the cabinet of the switchgear as well as to prevent contact failure between the conductive part of the switchboard and the power lead-in line 110 or the power lead-out line.

Here, the elastic force of the spring member 50 is provided between the connection plate 10 and the flow plate 20 so that the elastic force of the spring member 50 does not deform the outer shape of the housing of the distribution board.

The contact member 60 provided at the edge of the flow plate 20 in a state where the spring member 50 is installed between the connection plate 10 and the flow plate 20 is formed on the support frame 30 So as to be in an interviewed state on the inner surface of the insertion groove 31.

The connection plate 10 and the flow plate 20 may be provided with a release preventing piece 55 for preventing the spring member 50 from being released. That is, the release preventing piece 55 has an inner diameter larger than the outer diameter of the spring member 50, and one side in the longitudinal direction of the spring member 50 is connected to the release preventing piece 55 And the other longitudinal side is inserted into the release preventing piece 55 provided on the connecting plate 10 so that the mounting position of the connecting plate 10 and the moving plate 20 is not changed.

The support frame 30 is formed with an insertion groove 31 at its inner periphery to insert a contact member 60 formed at the edge of the flow plate 20, (60) is installed in an inner side of the insertion groove (31), and one end is coupled to the connection plate (10).

At this time, the support frame 30 is preferably installed on the connection plate 10 in a number equal to the number of the contact members 60 formed on the flow plate 20.

Here, a contact pad 62 made of brass is detachably installed in the insertion groove 31 of the support frame 30. At this time, the contact pads 62 may be provided only on one side and not on the other side.

Since the contact member 60 of the flow plate 20 is made of a steel material and the contact pad 62 is made of a brass material, the flow plate 20 can smoothly flow. That is, when the flow plate 20 flows in a state where the contact member 60 and the contact pad 62 are in contact with each other, a frictional force is generated between the contact member 60 and the contact pad 62, If the contact member and the contact pad are made of the same steel material, they may be mutually fused by frictional heat generated by mutual friction to restrict the flow of the flow plate 20. Therefore, in the present invention, the contact member and the contact pad are made of brass and steel so as to have different properties, so that the flow plate 20 can smoothly flow. In other words, the frictional heat generated between the contact member and the contact pad during flow of the flow plate 20 while the contact member 60 made of steel is in contact with the contact pad 62 made of brass, And the coating formed between the contact member and the contact pad performs a lubrication function to allow the flow plate 20 to smoothly flow.

In addition, since the contact pad 62 is detachably mounted to the insertion groove 31 of the support frame 30, when the brass is worn, the contact pad 62 can be easily replaced and the maintenance can be simplified. In the meantime, the present invention has been described as constituting the contact member and the contact pad with brass and steel. However, the present invention is not limited to this and can be replaced with another material.

The spacing frame 40 is formed in a cylindrical shape having a flange and spaced apart from the switchboard housing 200 by a predetermined distance from the flow plate 20. At this time, a through hole 42 is formed at the center of the separation frame 40 so that the power lead-in line 110 or the power lead-out line is penetrated to be connected to the switchboard enclosure 200. The spacer frame 40 may further include a bearing member for providing a smooth flow of the power lead-in wire 110 or the power lead-out wire.

A function of absorbing or buffering vibration energy generated from a building when an earthquake occurs through the earthquake-proof apparatus 100 constructed as described above or preventing damage to a cable tray will be described.

If an earthquake occurs and a shaking in the lateral direction occurs on the building, the cable tray installed on the building is also shaken.

In this state, the connecting plate 10 mounted at the end of the cable tray 120 is inclined in the direction of the shaking, and the spring member 50 on the tilting connecting plate 10 is compressed. When the direction of vibration is changed, the spring member to be compressed is also changed. By this operation, a considerable amount of earthquake vibration energy can be absorbed by the spring member, and breakage of the switchgear housing 200 can be prevented.

On the other hand, the compressed spring member can be quickly returned by the elastic force in a compressed state by the self-elastic force, because the contact member 60 provided at the edge of the flow plate 20 strongly hits the support frame 30 The safety of the structure can be impaired. In the present invention, the urethane member 51 having a certain elastic force is provided inside the spring member 50 to delay the recovery speed due to the elastic force of the spring member 50, So as to effectively prevent damage.

That is, when an earthquake occurs and the spring member 50 is compressed in a state where the urethane member 51 is installed inside the spring member 50, the urethane member 51 is compressed at the same time. At this time, 51 expand in the lateral direction and come into contact with the inner periphery of the spring member 50. [ In this state, the spring member 50, which has been compressed, does not return quickly due to the urethane member 51 upon resilient return by its own elastic force. In other words, as the expansion of the urethane member 51 in the lateral direction is contracted, the state of being in contact with the inner peripheral edge of the spring member 50 is gradually released, and the spring member 50 is resiliently returned, Time is delayed.

As a result, the urethane member 51 installed inside the spring member 50 delays the quick return of the spring member 50, thereby preventing a negative effect on the structure.

In the meantime, when the building is shaken up and down due to an earthquake or the like, the bottom seismic device 150 absorbs or buffers the vibration, and the process of absorption or buffering is the same as described above A detailed description thereof will be omitted.

6, when the present invention is applied to a wall panel mounted on a wall surface, the earthquake-proof apparatus 100 is mounted on the power inlet line 110 connected to the distribution board housing 210, The earthquake-proof apparatus 100 is also mounted on the power lead-out line 112 drawn out from the power line 210. The wall surface 130 forming the side surface can be constructed by mounting the earthquake-proof apparatus according to the present invention or a known earthquake-proof apparatus.

Therefore, when an earthquake occurs, the vibrations of the building and the distribution board can be independently absorbed or canceled, and it is possible to prevent damage due to poor contact such as short-circuiting or opening with the power lead-in line connected to the distribution board or the power lead- .

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention if they are apparent to those skilled in the art.
