Description

[0001] The present invention relates to a seismic switchgear equipped with a shock absorbing crista structure,

More particularly, the present invention relates to a seismic retrofit switchboard having a protruding structure buffering means so as to attenuate not only the transverse waves of an earthquake but also the influence of longitudinal waves so that the safety of the switchboard can be attained.

The switchboard is installed in various facilities or buildings, and distributes the power to the power consumption equipment inside the facility or the building by supplying power from the power plant down to low pressure.

In order to supply the electric power to the switchboard, various devices including a transformer, a converter, a breaker, and an earth leakage detector are built in. However, there are many current contacts that are energized with external circuits for each device, which is vulnerable to external vibration. In addition to various buildings including residential buildings such as apartments, the switchboards are essential devices in various industrial facilities. If the power supply is stopped due to abnormalities of the switchboard, it may cause considerable damage and inconvenience. Therefore, a means is needed to protect the switchgear from external vibrations.

As a vibration source affecting the switchboard, a typical example is an earthquake. In addition to an earthquake, there may be various vibrations generated in equipment installed in a switchboard, and there is vibration generated in other installation environments of a switchboard.

An earthquake is a P wave whose direction of vibration and direction coincides with each other, an S wave whose direction of vibration is perpendicular to the direction of the vibration, and a surface wave of which vibration of horizontal and vertical directions is mixed.

At this time, the P wave induces the horizontal direction vibration in the switchboard, and the S wave causes the vertical direction vibration, and the surface wave causes the vibration in the form of mixing the vertical direction and the horizontal direction.

Therefore, in order to prepare for the vibration of the earthquake, a means for attenuating or absorbing both vertical and horizontal vibrations is required.

In addition, in addition to earthquakes, various vibrations can affect the switchboard. In particular, vibrations caused by transportation means or surrounding facilities are vibrations that last for a long time, which may lead to a minute displacement of equipment due to vibration accumulation.

As to the prior art for attenuating or blocking vibration of an earthquake, most of the techniques are for attenuating vertical vibration, and it is hard to find a technique for actively attenuating or absorbing the vibration in the horizontal direction.

Furthermore, there is no technique for attenuation or removal of ordinary vibration that may seriously affect the life of the equipment other than earthquakes. In particular, There is no such thing as a switchboard equipped with means to make it possible.

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

As shown in Figs. 1 and 2, the present invention comprises a switchboard 1, a variable frame 10, and a buffer module 13.

The switchgear (1) refers to a switchboard installed in an ordinary facility, a factory or a building, and the inside of the steel enclosure (2) houses power distribution devices for distributing and supplying electric power to facilities or points within the building.

2, the variable frame 10 is a frame provided between the base 5 of the lower portion of the switchgear 1 and the bottom of the power distribution panel, and includes a top plate 11 formed of a rigid member, And a lower plate 12 arranged to face the upper plate 11 at the lower part and separated from the upper plate 11. The upper plate 11 constituting the variable frame 10 integrally extends downward from the upper horizontal board 111 and the upper horizontal board 111 having a shape and an area corresponding to the bottom surface of the switchboard 1 The lower plate 12 is integrally formed with the lower horizontal plate 121 and the lower horizontal plate 121 having a shape and an area corresponding to the shape of the lower surface of the switchboard 1, And a lower vertical plate 122 which is made of a metal.

6, the upper and lower vertical plates 112 and 122 may be coupled to each other in a face-to-face manner to form a box shape. The upper plate 11 and the lower plate 12 may be formed to have a small size so that the upper plate 11 may be inserted into the lower plate 12 or the lower plate 12 may be inserted into the upper plate 11 As shown in FIG.

6, the upper plate 11 and the lower plate 12 are formed to be smaller than the bottom size of the switchboard 1, and the upper plate 11 and the lower plate 12 are formed at a plurality of locations below the switchboard 1, May be installed.

As shown in FIGS. 2 and 3, the buffer module 13 is an elastic material buffering member disposed between the top plate 11 and the bottom plate 12. The buffer module 13 is separated from the buffer module 13 in a horizontal direction at a predetermined height, The vibration energy of the lower block 133 inserted between the block 131 and the lower block 133 and between the upper block 131 and the lower block 133 is varied according to the ambient vibration, And a connecting member for connecting the side surface of the upper block 131 to the side surface of the lower block 133. [ Accordingly, the upper block 131, the insulating cushion 132, and the lower block 133 are installed in this order from top to bottom.

Here, the bottom surface of the upper block 131 and the upper surface of the lower block 133 are formed to be curved rather than flat, and when the curved surface 1311 protruding from one another is formed, the other one of the depressions 1331 May be formed to be more firmly engaged than in the case of being formed in a plane.

However, since the P waves in the seismic waves cause the horizontal vibration, a structure is needed in which the vibration in the horizontal direction can be absorbed and dissipated. Therefore, the insulating cushion 132 is inserted between the upper block 131 and the lower block 133.

The insulating cushion 132 is formed to correspond to the shape of the curved surface 1311 of the bottom surface of the upper block 131 and the shape of the depressed surface 1331 of the upper surface of the lower block 133. [ The upper block 131 and the lower block 133 are firmly engaged with each other and at the same time, mutually freely variable within the elastic range of the insulating cushion 132 in the horizontal direction, The horizontal vibration of the base 5 can be blocked from being transmitted to the switchboard 1.

In this case, the projecting surface 1311 and the recessed surface 1331 formed on the bottom surface of the upper block 131, the insulating cushion 132 and the upper surface of the lower block 133 may be hemispherical, as shown in FIG. 2 . The protruded surface 1311 and the depressed surface 1331 are both hemispherical so that the protruded surface 1311 can be pushed by the same elastic force in all directions with respect to the depressed surface 1331, (133) The mutual action between them can be made softer and more free.

The hemispherical depressed space formed by the depressed surface 1331 of the upper surface of the lower block 133 is formed larger than the hemispherical volume formed by the curved surface 1311 of the bottom surface of the upper block 131, The hemisphere formed by the upper block 131 and the lower block 133 can be inserted more deeply into the hemispherical space formed by the depressed surface 1331 so that the relative variable is effectively prevented from proceeding too far between the upper block 131 and the lower block 133 .

The connecting member connecting the side surfaces of the upper block 131 and the lower block 133 may be a wire rope 134 formed by twisting a plurality of steel wires with a predetermined curvature. That is, the upper block 131 and the lower block 133 are separated from each other except for the connecting material, so that the upper block 131 and the lower block 133 can be separated from each other by up-down vibration.

At this time, in order to prevent the separation of the upper block 131, the insulation cushion 132, and the lower block 133, and also to more thoroughly perform the vibration damping action in the vertical direction and the horizontal direction of the insulation cushion 132, Is installed. Since the wire rope 134 is formed by twisting a plurality of steel wires, the wire rope 134 has a considerably high rigidity, so that the connection between the upper block 131 and the lower block 133 is surely ensured. At the same time, however, the wire rope 134 is not a monolithic single-stiffness member, but a plurality of members are twisted to each other, so that the wire rope 134 has a uniform elasticity as a whole. Accordingly, it is possible to prevent separation between the upper block 131 and the lower block 133 and to attenuate both the horizontal and vertical vibrations due to the wire rope 134. Further, since the elastic modulus of the insulation cushion 132 and the elastic modulus of the wire rope 134 are different from each other, the resonance of the wire rope 134 is effectively suppressed.

2, a cushioning elastic plate 16 may be inserted between the upper vertical plate 112 and the lower vertical plate 122, as shown in FIG.

4A and 4B, a plurality of buffer protrusions 162 and 163 are formed on both sides of the buffer elastic plate 16 at regular intervals in parallel to each other. The protrusions 162 and the buffer protrusions 163 formed on the other surface are orthogonal to each other in the longitudinal direction.

Comparing one surface of the cushioning elastic plate 16 shown in Fig. 4A and the other surface of the cushioning elastic plate 16 shown in Fig. 4B, the directions of the linear cushioning protrusions 162 and 163 formed on both surfaces cross each other at right angles Able to know.

The long buffering protrusions 162 and 163 of the buffering elastic plate 16 can provide a greater elastic force than the buffering protrusions 162 and 163 do not have. However, if the buffer bushing protrusions 162 and 163 formed on one surface and the other surface of the buffer bushing plate 16 are formed in the same direction, the elasticity of the buffering bushing plate 16 may only be increased to such an extent that the thickness of the buffering bushing plate 16 becomes thick.

However, since the linear buffer bosses 162 and 163 on both sides of the buffering elastic plate 16 are formed so as to cross each other at right angles to each other, the entire buffering elastic plate 16 is uniformly dispersed in contact on both sides, And the buffering effect due to the elastic force is further improved than in the case where the protruding thickness is made up to the thickness of the buffering elastic plate 16 by using more materials and the protrusions are not formed, It is effective.

A third buffer module 14 may be installed in a region indicated by a dotted circle in FIG. Although the third cushioning module 14 itself is not shown, a spring or straight wire rope may be installed at the center, and a bent wire rope may be installed at the side to assist the horizontal and vertical vibration damping operation.

6A, a second buffer module 20 may be installed between the devices 3 inside the switchgear 1 and between the device 3 and the inner bottom surface of the switchgear 1. 6B, the second buffer module 20 includes support plates 211 and 212 attached to the wall surface of the internal equipment 3 or the bottom surface of the device 3 and the bottom of the switchboard 1, 211, 212) of the wire rope (213). Where the wire rope 213 in the wire rope cushion constituting the second cushioning module 20 is much smaller in cross-sectional diameter than the wire rope 134 in the cushioning module 13 and behaves more flexibly.

As shown in FIG. 2, between the bottom surface of the upper horizontal board 111 and the upper surface of the upper block 131, and between the bottom surface of the lower block 133 and the upper surface of the lower horizontal board 121, A mesh buffer 15 may be installed. Since the wire mesh buffer 15 is a member made of a rigid material and is made of a porous material, it can have a sufficient elasticity to actively absorb the buffering effect, while the vibration energy is deformed into heat energy and heat is released to the pores of the wire mesh buffer 15 The vibration can be attenuated and dissipated. The wire mesh buffer 15 also acts to suppress resonance.

In the meantime, the control section 30 may be further provided in the seismic retrofitting / securing section according to the present invention. The control unit 30 includes a camera 31 installed in the interior of the switchboard 1 for acquiring an image targeted at a certain point on the surface of the internal device 3 of the switchboard 1, A converter (not shown) for receiving the image of the image acquiring device 34 and converting the image into digital information, and a controller (not shown) for computing the spatial coordinates of the predetermined point An arithmetic unit for calculating the degree of displacement due to vibration, and an image display unit for displaying the degree of displacement due to the spatial coordinates and the vibration.

When an earthquake occurs, various devices (3) and components installed in the switchboard (1) may be tripped due to an impact of an earthquake.

This may lead to connection failure, short circuit, short circuit, disconnection, etc., resulting in electric fire or failure of the power supply facilities.

Therefore, if it is not immediately known whether the installation position of the device 3 has been changed due to the vibration, it takes a considerable time to grasp and maintain the damage situation, and serious damage may occur due to a long time shutdown.

Accordingly, in the present invention, a three-dimensional coordinate of the device 3 is obtained by using the camera 31, thereby proposing a system capable of detecting whether the positional displacement of the device 3 occurs and the displacement distance in real time.

At this time, the object where the positional displacement occurs is the devices 3 inside the switchboard 1. Problems such as connection failure, short circuit, short circuit, disconnection due to the occurrence of positional displacement of the device (3) due to vibration are caused by relative positional displacement between the devices (3).

In order to precisely understand the problem caused by the occurrence of the displacement of the device 3, it is necessary to determine how the displacement of each device 3 from the initial installation position due to the vibration occurs and the displacement of the devices 3 due to the vibration It is necessary to determine at which point the precise position of each device 3 is located.

That is, the displacement path of each device 3 and the precise position after the displacement must be grasped.

In this case, the camera 31 for measuring the displacement of the device 3 is disposed in the interior of the switchboard 1, more precisely, on the inner wall of the enclosure 2 of the switchboard 1. Therefore, even if displacement occurs due to the vibration of the switchboard 1 itself, the camera 31 is configured not to be displaced separately from the enclosure 2 of the switchboard 1.

The camera 31 is capable of capturing the degree to which each device 3 has been displaced in the initial installation position in the interior of the switchboard 1 when the devices 2 are displaced due to vibration in the interior of the switchboard 1 .

Although the camera 31 is not perfectly fixed at one point, it is important to note that the position of each device 3 inside the switchgear 1 is not limited to the position of the switchgear 1, And how much the position has changed in the initial installed position inside. Therefore, the displacement problem of the switchboard 1 itself will be described later.

In order for the camera 31 to capture the displacement of each device 3 in the switchboard 1, a reference point whose position is unchanged for the camera 31 is required.

10, since the camera 31 is attached to the inner wall of the enclosure 2 of the switchboard 1, the reference point must also be present on the inner surface of the enclosure 2 of the switchboard 1 as shown in FIG.

This is because the relative position between the reference point and the camera 31 should be unchanged even if the camera 31 attached thereto is displaced due to the displacement of the enclosure 2 due to the vibration.

Therefore, the reference point should be at any point inside the switchgear (1) enclosure (2). In FIG. 10, the reference point is defined as the bottom of the inner surface of the cabinet (1) of the switchboard (1), but it is not necessarily the bottom surface and the reference point may be the wall surface or the ceiling.

8, the reference markers 312 may be provided at the reference point, and the internal devices 3 of the switchboard 1 may be mounted on the device frame 4 fixedly installed on the bottom surface or the side surface of the switchboard 1 .

In this case, when the vibration due to the earthquake occurs, the internal devices (3) of the switchboard (1) may be displaced little by little on the device frame (4).

Since the device frame 4 itself is fixed to the inside of the switchboard 1, the device frame 4 is not separated from the enclosure 2 of the switchboard 1 and is not displaced.

Therefore, the reference point and the reference reflection marker 312 may be installed in the apparatus frame 4. [

At this time, the reference reflection marker 312 is installed on the inner bottom surface of the device frame 4 or the enclosure 1 of the switchboard 1 to provide a background image as a reference of spatial coordinates.

In addition, since the internal devices 3 of the switchboard 1, which is the object of the displacement observation, can be displaced independently of the switchboard 1 and the device frame 4 due to vibration, the internal devices 3 are provided with the variable reflection markers 311 Is attached.

The variable reflection markers 311 are attached to the surface of the appliance enclosure in which the respective devices 3 inside the switchboard 1 are individually housed.

In this case, when a vibration due to an earthquake or the like is generated and a displacement of each device 11 in the switchboard 1 is generated, the camera 31 moves the variable reflection marker 312 with reference to the reference reflection marker 311 Thereby capturing the displaced position and the trajectory of each device 3 in the switchboard 1 to which the variable reflectance markers 312 are attached.

Here, the reference reflection marker 312 is a correction means capable of capturing the changed position of the variable reflection marker 311 even if the position of the variable reflection marker 311 is changed.

Thus, the displacement trajectory and position of the devices 3 can be grasped by grasping the moving position of the variable reflection marker 311 before and after the vibration due to the earthquake with reference to the spatial coordinates of the reference reflection marker 312.

For reference, the variable reflection marker 311 and the reference reflection marker 312 are used as an image target of the camera 31, and the error can be reduced.

The variable reflection marker 311 and the reference reflection marker 312 may be formed in such a manner that a spherical object is attached to the circular plate.

Since the variable reflection markers 311 and the reference reflection markers 312 are formed in a spherical shape at the top, a vertical surface can be provided with respect to the photographing direction of the camera 31 regardless of the position of the camera 31, 31) can be obtained.

Since a reflective image can be obtained by using a reflection marker, installation cost can be reduced because a low-resolution camera can be used. In this case, the measurement error can be kept below 0.002 mm. However, an active marker (not shown) for transmitting an infrared signal may be attached instead of the passive reflective reflective marker 311 and the reference reflective marker 312 shown in FIG.

The techniques for measuring spatial coordinates or displacements of an object in a three-dimensional space using the camera 31 are well known in the art, and a detailed description thereof will be omitted here.

Representative three-dimensional displacement measurement techniques include homography-based measurement technology and DLT (Direct Linear Transformation). The camera 31 is disposed inside the switchboard 1 so that the position of the device 3 inside the switchboard 1 is important so that the positional displacement of the device 3 inside the switchboard 1 can be grasped, A camera may be installed outside the switchboard (1) to monitor the positional displacement of the switchboard (1) itself.

The number of cameras 31 may be one, but two or more cameras are preferably disposed.

The camera 31 digitizes the image acquired by the camera 31 in the converter once the background image is acquired and transmitted to the converter at a point where no vibration occurs even if vibration of the earthquake occurs at a certain point inside the switchboard 1 , The computing device receiving the digital image information calculated by the converter calculates the spatial coordinates of the background image and sets it as the reference space coordinates.

In addition, the camera 31 acquires real-time images of certain parts of the internal devices 3 of the switchboard 1 and sends them to the converter to calculate the spatial coordinates of the devices 3 in the same manner as the space coordinate calculation of the background image.

At this time, by comparing the space coordinates of the background image acquired in advance and the spatial coordinates of the device 3 such as busbars inside the switchgear 1 in an algorithmic manner, it is determined whether the positional displacement of the devices 3 occurs It can be grasped whether the positional displacement of the devices 3 is occurring.

The control unit 30 may further include an alarm unit (not shown) that generates an alarm according to the tilt of the switchboard 1 while receiving the tilt angle data of the switchboard 1 from the tilt sensor 32.

In this case, the slope of the switchgear 1 where an alarm starts to be generated can be appropriately set according to the surrounding environment such as the specification of the switchboard and the installation position.

When the busbar (1) is tilted by vibration due to an earthquake or the like and the displacement of the busbar and the equipment occurs, the insulation distance between the internal live parts is narrowed to within the safe distance according to the relevant regulations, or the distance between the busbar, If an alarm is generated by the alarm, a means for automatically shutting off the power supplied to the switchboard may be provided.

The tilt sensor 32 is preferably installed on the upper portion of the switchboard 1 so that the inclination of the switchboard 1 can be captured even if the inclination of the switchboard 1 changes slightly (not shown).

Here, the tilt sensor 32 includes both an analog tilt sensor and a digital tilt sensor, but in the case of an analog tilt sensor, means for converting the tilt measurement value to a digital value so that the tilt measurement value can be transmitted to the control unit .

As described above, the spatial coordinates acquisition by the tilt sensor 32 and the camera 31 can capture the displacements generated in the switchboard 1 and the internal equipment 3 of the switchboard 1. In addition, a separate camera (not shown) may be additionally disposed on the outside for measuring the displacement of the switchboard 10 itself.

As shown in FIG. 10, the background image, which is a non-fluctuating point obtained in advance within the switchboard 10, a certain portion of the device buses 11-1 disposed inside the switchboard 10, 10, a variable reflection marker 311 may be attached to a predetermined portion of the outer side as shown in FIG.

In addition, a reference reflection marker 312 is provided to acquire the background image at a point where displacement does not occur even if vibration of the earthquake described above occurs.

Meanwhile, in the earthquake-resistant switchboard according to the present invention, a power monitoring and control system and a fire receiver 60, which can monitor the possibility of an earthquake while periodically or real-time receiving various data related to an earthquake and an earthquake- May be further included.

The power monitoring and control system and the fire receiver (60) are connected to a network connected to the Korea Earthquake Research Institute or an earthquake research center, and can be used for earthquake data, GPS data, or any earthquake that may affect the area where the switchboard (1) Data on the possible occurrence conditions can be received. At this time, the earthquake can be predicted through the received data, and the long-term geological condition of the location of the switchboard 1 can be grasped based on the accumulation of the received data.

The accumulated data can be usefully used to predict earthquakes and cope with earthquakes in the future, and it is possible to cope with earthquakes more rapidly in actual earthquake situations.

For this purpose, a server (not shown) for storing data may be provided in the power monitoring and control system and the fire receiving unit 60.

And a control power source 33 for supplying a separate power source to the control unit 30, the power monitoring control system, and the fire receiver 60. The control power source 33 may be supplied with power from a storage battery (not shown) so that the power source can be supplied even if the power source is short-circuited due to an earthquake.

9 and 12, the emergency power generation module 40 includes a case 41, a vibration amplifying member 42 embedded in the case 41, a power transmitting member and a generator 47, Converts the vibration energy received from the foundation into rotational energy, drives the internal generator, and supplies power to the control power source (33) in an emergency with the produced electric power to operate the control unit (30).

10, the vibration amplifying member 42 includes a reciprocating guide 421, two springs 423 inserted into both ends of the reciprocating guide 421, and two springs 423 inserted between both springs 423, A piston 422 which moves and a piston arm 43 fixedly connected to the piston 422. Accordingly, when vibration is transmitted to the emergency power generation module 40 due to the influence of the vibration, the piston 422 vibrates in the reciprocating guide 421. At this time, the influence of the wind 423 influences the pendulum motion Is switched to the repeated reciprocating motion, the number of times of vibration of the emergency power generation module 40 is amplified. That is, the piston 422 oscillates several times during the vibration of the emergency power generation module 40 due to the effect of the earthquake.

Here, the reciprocating guide 421 may be a cylindrical sliding bearing or a rigid pipe. When the reciprocating guide 421 is a rigid pipe, graphite is applied to the inner circumferential surface to prevent deterioration due to friction, and interference due to friction between the spring 423 and the inner circumferential surface of the reciprocating guide 421 can be minimized. 10, a long hole is formed in the reciprocating guide 421 in the longitudinal direction, so that the piston arm 43 can freely reciprocate together with the piston 422.

The piston arm 43 fixedly connected to the piston 422 transmits vibration to the power transmitting member. The end of the piston arm 43 is connected to one end of the connecting rod 44 by a hinge 431 and the other end of the connecting rod 44 is hinged to the rotary arm 45 as shown in Fig. A pin journal 451 formed at a position eccentric to one surface of the rotary arm 45 is inserted into the other end of the connecting rod 44 so that the rotary arm 45 and the connecting rod 44 are hingedly engaged.

The reciprocating motion of the piston 422 due to the connecting rod 44 and the rotary arm 45 is deformed into rotational motion. The rotary motion of the rotary arm 45 is transmitted to the rotary amplifying member. The principle in which the reciprocating motion of the piston 422 is converted into the rotational motion of the rotary arm 45 is shown in Fig. 11 in order.

11, the rotation amplifying member is composed of a rotary cap 461 connected to the rotary arm 45 and rotated together therewith, a rotary cap 461 inserted into the rotary cap 461, rotated at the same angular speed as the rotary cap 461, A plurality of satellite gears 4632 which are engaged with the inner circumferential surface of the ring gear 4631 and rotate in conjunction with the ring gear 4631 and have a smaller diameter than the ring gear 4631, And a planetary gear 463 composed of a sun gear 4633 which is engaged with both of the planetary gears 4632 and rotated.

The sun gear 4633 disposed in the center of the planetary gear 463 can be rotated several to ten times or more when the planetary gear 463 is adopted to the rotation amplifying member so that the rotary arm 45 is rotated once. Here, the rotation shaft 471 of the generator 47 is inserted into the center of the sun gear 4633, and the generator 47 is driven. Therefore, when the vibration of the emergency power generation module 40 due to the earthquake occurs once, the rotary shaft 471 of the generator 47 can be rotated several tens of times so that electric power can be generated in the generator 47 even if there is minute wind vibration Sufficient rotational kinetic energy can be delivered.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
