Description

Technical Field [0001] The present invention relates to a seismic system and apparatus for providing horizontal and vertical earthquake resistance for a transmission /

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake-proof system and a vibration-damping system for providing a horizontal vibration damping force and a vertical vibration damping force for a switchboard, and more particularly, To a horizontal earthquake-proof force and a vertical earthquake-proof force for a transmission /

Particularly, the vibration resisting device of the present invention is constructed by using the resilient restoring force of the rubber part 120, which is a rubber material, and the horizontal sliding movement of the base part 130 and the core part 140, It can efficiently absorb vibration against vibration and vertical vibration. It does not need a separate power source for driving the earthquake-proof device, so maintenance cost or repair cost is low, and the earthquake-proof device is modularized so that it can be easily installed in electric power facilities requiring earthquake- .

The switchgear is a device that distributes power to various facilities by transforming the high voltage power supplied from the power station and the substation into low voltage by incorporating various power facilities such as transformer, breaker, converter, and relay.

Since the switchgear is directly installed on the ground or installed in buildings such as factories and apartments and is operated for a long time for 24 hours, it is easily exposed to an external shock such as an earthquake and the power facilities are connected to many contacts. to be.

If vibration or shock due to external force is applied to the switchgear, the impact is transmitted to the cabinet of the switchgear, damage to the internal power equipment, damage to the electrical contacts to which each power equipment is connected can not provide stable power supply, An electric shock accident may occur.

In recent years, large and small earthquakes have frequently occurred on the Korean Peninsula. In particular, earthquakes in which structures are collapsed in Gyeongju area are important to secure the stability of the building structure. In the case of the switchboard installed in the building, Standards are being strengthened over the past.

Conventional methods for earthquake-resistant design of switchgear have been designed to prevent distortion by installing a stiffener on the body, or to withstand vibrations using a fastener. The further seismic design is to install a seismic device that absorbs vibration by using a spring or shock absorber.

Conventionally, a large number of seismic devices are disclosed. Vibration absorption methods can be classified into a seismic device that absorbs vertical vibration, a seismic device that absorbs horizontal vibration, and a seismic device that can simultaneously absorb vertical and horizontal vibration.

Vertical vibration is generated mainly in a relatively monotonous form compared to horizontal vibration in the vertical direction. Thus, many vibration isolators have been conventionally invented to absorb vertical vibration, but since horizontal vibration occurs in a complicated form compared with vertical vibration, The seismic equipment is relatively small, and in order to attenuate the complex type of vibration, a horizontal seismic device with a complicated structure is common.

(Japanese Patent No. 10-1326401) for attenuating vibrations in the horizontal direction in the related art has a structure in which a spherical shape inserts a ball between convex plate-like plates and moves left and right according to external vibration, to be. However, in order to increase the restoring force, the center of the plate-shaped plate must be formed deeply. When the center of the plate is formed deep, Vibration may be generated, which may cause vibration and resonance in the vertical direction externally applied, which may lead to further damage.

The other prior art (Japanese Patent No. 10-1397804) seismic device attenuates the horizontal vibration by using the restoring force of the coil spring. In order to attenuate vibration in various horizontal directions, The structure is complicated due to the necessity of installing the spring, which results in a large production cost and maintenance cost.

Another conventional technique (Patent No. 10-1305302) is to arrange an electromagnet and a permanent magnet so as to face each other, and to connect an external power source to the electromagnet to damp horizontal vibration, However, since a complex controller for controlling the external power source and the electromagnet is required, the structure becomes more complicated, and the manufacturing cost and the maintenance cost become more necessary.

Therefore, new seismic equipments with simple structure and low maintenance cost are required, while absorbing the horizontal vibration and vertical vibration applied to the switchboard more efficiently.

As shown in FIG. 2, a part of the inner surface of the cylindrical upper part (part A in FIG. 2) is formed on one side of the base slip top plate 131 (Part B in Fig. 2) is in contact with one side of the base slip bottom plate 132. The inner bottom surface of the base slip bottom plate 132,

A structure in which a part of the inner surface of the cylindrical upper part of the rubber part 120 and a part of the inner surface of the cylindrical lower part are connected to one side of the base slip top plate 131 and the base slip bottom plate 132, respectively, And has two different embodiments as shown.

First, the contact connection by thread engagement will be described with reference to the upper drawing of Fig. 9 and Fig. 11 (a).

A first screw thread 121 is formed on the inner circumferential surface of the cylindrical upper portion of the rubber portion 120 contacting with the outer circumference of one side of the base slip top plate 131 A second screw thread 122 is formed on the inner circumference of the lower portion of the cylindrical portion of the rubber portion 120 which is in contact with the outer circumference of one side of the lower plate 132 (upper portion B in FIG. 9)

A screw thread corresponding to the first screw thread 121 is formed on the outer surface of the base slip top plate 131 in contact with the portion where the first screw thread 121 is formed 11 (a), a thread corresponding to the second thread 122 is formed around the outer surface of the base slip lower plate 132 in contact with the portion where the second thread 122 is formed And the first thread 121 and the second thread 121 formed on the rubber portion 120 are engaged with the threads formed on the base slip top plate 131 and the base slip bottom plate 132, .

The contact connection by the protruding end, which is another embodiment, will be described with reference to the lower part of Fig. 9 and Fig. 11 (b).

A first protruding end portion 125 is formed on the inner circumferential surface of the cylindrical upper portion of the rubber portion 120 which is in contact with the outer circumference of one side of the base slip top plate 131, A second projecting end 126 is formed on the inner circumference of the cylindrical lower portion of the rubber portion 120 which is in contact with the periphery of one side outer surface of the lower plate 132

A first insertion groove 1311 corresponding to the shape of the first projecting end portion 125 is formed around the outer surface of the base slip top plate 131 in contact with the portion where the first projecting end portion 125 is formed, And a second insertion groove 1321 corresponding to the shape of the second projecting end 126 is formed around the outer surface of the base slip lower plate 132 in contact with the portion where the second projecting end 126 is formed The first protruding end portion 125 and the second protruding end portion 126 formed on the rubber portion 120 are formed in the same manner as the base slip upper plate 131 and the base slip lower plate 132, Are inserted into the first and second insertion grooves 1311 and 1321, respectively.

A portion of the inner surface of the cylindrical upper portion of the rubber portion 120 and a portion of the inner surface of the lower cylindrical portion of the rubber portion 120 are connected to one side of the base slip top plate 131 and the base slip bottom plate 132, A metallic cylindrical band 127 may be formed on a part of the outer surface of the cylindrical upper part of the rubber part 120 and a part of the outer surface of the cylindrical lower part.

4 and 9, a third thread 123 is formed on the inner surface of the cylindrical middle portion and a helical spring wire 124 is inserted into the third thread 123, Respectively.

The helical spring wire 124 inserted into the third thread 123 formed on the inner surface of the cylindrical portion of the rubber portion 120 is deformed when the base upper plate 111 moves in the horizontal direction due to a horizontal force due to an earthquake or the like, together with the rubber part 120, in the horizontal direction.

At this time, the base upper plate 111, which is moved in the horizontal direction by the material characteristics (rubber material) of the rubber part 120, which is made of rubber material, and the spiral spring wire 124 which has been stretched, And the base upper plate 111, which is moved in the horizontal direction, is returned to the initial position.

That is, when the rubber part 120 is stretched in the horizontal direction due to the horizontal force due to an earthquake or the like, the elastic property of the rubber part 120 of the rubber part 120 and the elastic return of the helical spring wire 124 The base upper plate 111 moved in the horizontal direction by the force is provided with the elastic restoring force for returning to the initial position and returned to the initial position.

The rubber part 120 having a closed hollow cylindrical shape protects the base slip plate part 130 and the core part 140 provided inside from the outside and also protects the core part 140 from external Thereby preventing foreign matter from entering.

The inner surface of the cylindrical upper portion of the rubber portion 120 is connected to one side of the base slip top plate 131 and the inner bottom surface of the cylinder is connected to one side of the base slip bottom plate 132, The base upper plate 111 moving in the horizontal direction due to a horizontal external force due to an earthquake or the like is connected to the base slip top plate 131 and is restricted from moving excessively in the horizontal direction.

Further, the rubber part 120, which is a closed hollow hollow cylindrical shape, may be formed in a corrugated corrugated pipe shape (also called a bellows shape).

This is because the corrugated bellows shape (aka bellows shape) has an effect of increasing the elastic return force of the rubber portion 120 in addition to the elastic return force provided by the helical spring wire 124 It is for this reason.

11, a third insertion groove 1312 is formed around one side of the outer surface of the base slip top plate 131, and a fourth insertion groove 1312 is formed around one side of the outer side surface of the base slip bottom plate 132. [ (1322)

A part of one end of the helical spring wire 124 shown in FIG. 4 is inserted and fixed into the third insertion groove 1312, and a part of the other end of the helical spring wire 124 is inserted into the fourth insertion groove 1322 And is inserted and fixed.

A part of one end of the helical spring wire 124 is inserted and fixed in the third insertion groove 1312 and a part of the other end of the helical spring wire 124 is inserted and fixed in the fourth insertion groove 1322 The reason for this is to prevent the base upper plate 111, which moves in the horizontal direction due to a horizontal external force due to an earthquake or the like, from moving excessively in the horizontal direction to excessively depart from the earthquake-proof apparatus 100.

Specifically, as described above, the inner surface of the cylindrical upper part of the rubber part 120 is connected to one side surface of the base slip top plate 131, and the inner surface of the lower cylindrical part is connected to the base slip lower plate 132 The base upper plate 111 moving in the horizontal direction due to a horizontal external force due to an earthquake or the like is connected to the base slip top plate 131 and is restricted from moving excessively in the horizontal direction.

At this time, a portion of one end of the helical spring wire 124 is inserted and fixed in the third insertion groove 1312, and a part of the other end of the helical spring wire 124 is inserted into the fourth insertion groove 1322 The base slip upper plate 131 and the base slip lower plate 132 are physically connected to both ends of the helical spring wire 124. The base slip upper plate 131 and the base slip lower plate 132 are connected to the base slip upper plate 131, The base plate 111 is restricted from being excessively moved in the horizontal direction so that the base plate 111 is not excessively separated from the vibration-proof device 100.

As a result, the base upper plate 111 is prevented from being excessively released by the rubber portion 120 and the helical spring wire 124 when a horizontal external force due to an earthquake or the like is applied.

When an external external force such as an earthquake occurs, an external force in the horizontal and vertical directions acts on the main body 200 of the switchgear and the damage to the power facilities installed in the main body 200 of the switchgear fixed by the external force in the vertical and horizontal directions The seismic apparatus 100 of the present invention absorbs the external force in the vertical direction or the horizontal direction due to the external external force to provide the horizontal quasi-

Particularly, in order to absorb an external force in the vertical direction or the horizontal direction, the main body 200 of the switchgear must be able to move in accordance with external external force in the horizontal direction or the vertical direction.

As described above, the structure in which the switchgear main body 200 is movable in the horizontal direction or the vertical direction in accordance with the external external force is an arc-shaped sliding movement in the arbitrary direction between the base slip plate portion 130 and the core portion 140 It is exercise.

Since the rubber part 120 is formed of a rubber material of elastic material and the helical spring wire 124 is formed on the inner surface of the rubber upper part 120, 111 are stretched so as to be movable in a horizontal direction with respect to the base lower plate 112 fixed to the ground or floor or the like and at the same time an elastic restoring force for restoring the base upper plate 111 moving in a horizontal direction to the initial position is provided In this process, the horizontal external force is absorbed by the earthquake and the like, and the horizontal earthquake force is provided.

That is, since the rubber part 120 is formed of a rubber material, which is an elastic material, and the helical spring wire 124 is formed on the inner side surface thereof, the base bottom plate 112 fixed to the ground or the floor through the second horizontal plate 320, 3 shows a base upper plate 111 which is moved in a horizontal direction with respect to the base lower plate 112. The base upper plate 111 is movable in the horizontal direction.

3, the base upper plate 111, which is moved in a horizontal direction with respect to the lower base plate 112 fixed to the ground or the floor through the second horizontal plate 320 by an external horizontal external force, The elastic restoring force of the elastic material of the elastic member 120 returns to the initial position as shown in FIG. 2. In this horizontal stretching and return to the initial position, The horizontal force exerted on the main body 200 is absorbed in the horizontal direction.

The elastic restoring force for restoring the moving base upper plate 111 to the initial position is provided by the above-described helical spring wire 124 formed on the inner side of the rubber part 120 as described above .

The base slip plate unit 130 includes:

And the lower surface of the core slip top plate 141 is formed in a concave spherical shape having a predetermined curvature so that the core slip top plate 141 of the core portion 140 is slid in an arbitrary direction, A base slip top plate 131 for guiding movement of the base slip,

The upper surface of the base slip plate 131 is connected to the base upper plate 111 and the lower surface of the base slip plate 131 is formed into a concave spherical shape having a constant curvature.

The lower surface of the base slip top plate 131 formed in a concave spherical shape having the constant curvature shown in FIGS. 2 and 8 is a convex spherical surface having a spherical curvature equal to that of the base slip top plate 131, The core slip top plate 141 of the core portion 140 can perform sliding movement in an arbitrary direction while being in surface contact with the upper surface of the core slip top plate 141 formed in a shape as shown in FIG. A guide surface is provided.

 As described above, when an external external force such as an earthquake occurs, a horizontal external force is applied to the main body 200 of the switchgear, and the power equipment installed inside the main body 200 fixed by the external force in the horizontal direction, In order to solve the problem caused by the horizontal external force, it is necessary to absorb the external force in the horizontal direction. In order to absorb the external force in the horizontal direction, the body of the switchgear 200 must move in accordance with the horizontal external force . The base upper plate 111 connected to the main body 200 through the first horizontal plate 310 is moved in the horizontal direction with respect to the base lower plate 112 fixed to the ground or the floor through the second horizontal plate 320 .

The configuration in which the base upper plate 111 can move in the horizontal direction with respect to the base lower plate 112 includes a base slip top plate 131 formed in a spherical shape having a lower surface in a concave shape, Shaped sliding movement of the core slip top plate 141 which is formed of the same material.

That is, before the external external force such as an earthquake occurs, the base slip top plate 131 formed in a spherical shape having a concave lower surface and the core slip top plate 141 formed in a spherical shape having a convex upper surface are shown in FIG. It is in the initial position as shown.

If an external external force such as an earthquake occurs, the base slip top plate 131 formed in a spherical shape having a concave bottom surface due to an external horizontal external force acts on the core slip top plate 141 formed in a convex spherical shape , And moves in a horizontal direction as shown in FIG. 3. The principle of moving the base slip is a convex spherical shape along the lower surface of the base slip top plate 131 formed in the concave spherical shape So that the upper surface of the formed core slip top plate 141 is subjected to an arc-type sliding movement in an arbitrary direction (a direction due to a horizontal external force due to an earthquake or the like).

That is, the upper surface of the core slip top plate 141, which is formed in a convex spherical shape, is slid on the lower surface of the base slip top plate 131 formed in a concave spherical shape by an external horizontal external force, The base upper plate 111 connected to the main body 200 through the first horizontal plate 310 is moved to the lower base plate 112 fixed to the ground or the floor through the second horizontal plate 320 So that it can move in the horizontal direction.

In order to allow the base upper plate 111 connected to the switchgear main body 200 to move in the horizontal direction with respect to the ground or the base lower plate 112 fixed to the floor through the second horizontal plate 320, The upper surface of the core slip top plate 141 formed in the shape of a convex spherical surface not only has a convex spherical sliding motion on the lower surface of the base slip top plate 131 formed in a concave spherical shape by an external horizontal external force, The bottom surface of the core slip bottom plate 142 formed in a spherical shape must also perform an arc-type sliding movement on the upper surface of the base slip bottom plate 132 formed in a concave spherical shape.

The principle of sliding movement between the core slip bottom plate 142 and the base slip bottom plate 132 is based on the principle of the arc sliding movement between the core slip top plate 141 and the base slip bottom plate 131 The same description of the operation will be omitted.

The core 140 may be arc-shaped in an arbitrary direction (direction by a horizontal external force due to an earthquake or the like) between the base slip plate 131 and the base slip plate 132 of the base slip plate 130 when an earthquake occurs. Type sliding movement and provides a vertical anti-vibration force, and has the following structural features.

As shown in FIGS. 8 and 10,

The upper surface of the base slip plate 131 is formed in a convex spherical shape having the same spherical curvature as the concave spherical surface of the base slip top plate 131, A core slip top plate 141 sliding in an arc shape,

The lower surface of the base slip lower plate 132 is formed in a convex spherical shape having the same spherical curvature as that of the concave spherical surface of the base slip lower plate 132, A core slip bottom plate 142 sliding in an arc shape,

The core slip plate 142 is connected to one side of the core slip top plate 141 and the other side is connected to the core slip bottom plate 142 to absorb a vertical external force due to an earthquake, ).

The top surface of the core slip top plate 141 formed in a convex spherical shape is formed in a shape of a concave spherical top surface of the base slip top plate 131 as shown in FIG. 2 before an external external force such as an earthquake occurs And is in surface contact with the lower surface.

The bottom surface of the core slip bottom plate 142, which is formed in a convex spherical shape, also has a base slip bottom plate 132 formed in a concave spherical shape as shown in FIG. 2 before an external external force such as an earthquake occurs, As shown in Fig.

At this time, when an external external force such as an earthquake occurs, the upper surface of the core slip top plate 141 is curved along the lower surface of the base slip top plate 131, which is formed in a concave spherical shape, Type sliding movement.

Similarly, when an external external force such as an earthquake occurs, the lower surface of the core slip lower plate 142 is curved along the upper surface of the base slip lower plate 132, which is formed in a concave spherical shape, Type sliding movement.

The lower base plate 112 fixed to the ground or the floor or the like through the second horizontal plate 320 by the above-mentioned arc-type sliding movement is guided through the first horizontal plate 310 to the lower portion of the main body of the switchgear 200 The base upper plate 111 is horizontally moved in accordance with the horizontal external force of an external external force such as an earthquake.

The core body 143 is connected to the core slip top plate 141 at one side and connected to the core slip bottom plate 142 at the other side as shown in FIG. And is formed of an elastic material so as to absorb vertical impact force to the main body 200 of the switchgear.

The reason why the core body 143 is made of an elastic material is to absorb a vertical external force generated when an earthquake occurs.

That is, when an earthquake or the like occurs, a vertical external force acts on the main body 200 of the switchgear. If the vertical external force is not absorbed, the power equipment installed inside the main body 200 of the switchgear is damaged .

Therefore, when the core body 143 is made of an elastic material, the core body 143, which is the elastic material, is contracted by the vertical external force when a vertical external force is generated by an earthquake or the like, absorbing the vertical external force, A vertical exertion force is provided to the main body 200 of the switchgear by absorbing a vertical external force due to an earthquake or the like.

10, a hollow portion 1431 vertically penetrating the central portion of the core body 143 is formed in the core body 143, and the hollow portion 1431 is formed in a circular arc shape in an arbitrary direction. And the core body 143 is a space for spraying a stress against a vertical external force applied to the core part 140 slidingly moving. The core body 143 is made of a urethane material.

The reason why the hollow portion 1431 is configured is that the core body 143 of the core portion 140 slidingly moves in an arc-like manner has a structure for ejecting stress on a vertical external force unevenly applied thereto. The core portion 140 having the arc-shaped sliding movement is in a slightly oblique state, not in the horizontal direction.

When the core 140 is in a horizontal state, a uniform vertical external force is applied to all the surfaces of the core body 143 of the core 140. However, when the core 140 is in a horizontal state, Uneven vertical external force acts on all the surfaces of the body 143, causing uneven vertical stress, and the core body 143, which is an elastic material, is twisted due to uneven vertical stress. If the hollow portion 1431 is configured Otherwise, the possibility that the core body 143 is deformed into a twisted state by the uneven normal stress becomes high.

Accordingly, when the hollow portion 1431 is formed, uneven vertical stress is injected into the hollow portion 1431, which reduces the possibility of deformation of the core body 143 due to normal stress.

The core slip top plate 141 and the core slip bottom plate 142 are formed in the core slab 140 such that the core slip top plate 141 and the core slip bottom plate 142 are arc- And the base upper plate 111 connected to the lower portion of the main body 200 of the switchgear is horizontally movable relative to the fixed base lower plate 112 by sliding movement so that horizontal exertion force with respect to the horizontal external force of the external external force, And the vertical compression force and the restoring force of the core body 143, which is an elastic material, in the vertical direction provide vertical exertion force against the vertical external force of the external external force such as an earthquake.

In the present invention, the concave spherical surfaces of the base slip plate 131 and the base slip bottom plate 132 of the base slip plate 130 and the core slip top plate 141 and the core slip bottom plate 142 are formed on the convex spherical surface thereof with a heat radiating coating or a metal coating for minimizing the heat and frictional force generated in the sliding movement of the arc.

As described above, the core slip top plate 141 of the core unit 140 performs an arc-type sliding movement while making mutual surface contact with the base slip top plate 131 of the base slip plate unit 130, The core slip lower plate 142 of the base 140 slides in an arc-like sliding contact with the base slip plate 132 of the base slip plate 130 and heat and friction force do.

The generated heat and frictional force are elements that interfere with the sliding movement of the arc type. It is necessary to minimize the heat and frictional force generated in the sliding movement of the arc type. To this end, the base slip top plate 131 and the base slip bottom plate And a convex spherical surface of the core slip bottom plate 141 and the core slip bottom plate 142, and a heat dissipation coating or a metal coating.

The heat dissipation coating is a known heat dissipation coating that minimizes heat generation due to friction, and the metal coating is also made of a metallic base slip top plate 131, a base slip bottom plate 132, a core slip top plate 141 and a core slip bottom plate 142 (Sliding) movement of the sliding surface of the base plate.

In order to minimize the heat and frictional force generated in the arc-type sliding movement, a concave spherical surface of the base slip plate 131 of the base slip plate 130 and a concave spherical surface of the core 140, Of the core slip plate 141 of the core slip plate 141 and the concave spherical surface of the base slip plate 132 of the base slip plate 130 and the concave spherical surface of the core slip bottom plate 142 of the core slip plate 141 The ball bearing 150 is formed between the convex spherical surfaces as shown in FIG. 5 in order to minimize the heat and frictional force generated in the sliding motion of the arc type.
