Description

Switchgear enclosure with seismic isolation inside frame {External case of distributing board having an seismic isolating device}

The present invention relates to an enclosure for a switchgear in which equipment for drawing electricity and equipment for distributing electricity are incorporated. More particularly, the enclosure for a switchgear made of a base plate, a frame, a door, a side plate, and a roof plate, By installing a seismic isolator having a "Y" shape on the door frame of the frame, it is possible to minimize the effect of the frame caused by the earthquake load.

In general, in order to use electricity in a building, it is necessary to receive power equipment for drawing electricity from an electric line, and in order to distribute the received electricity to each interior space of the building, a proper distribution equipment will be required.

Accordingly, the switchgear should be applied to buildings and structures as essential, and the switchgear should be safely protected and installed through a separate enclosure.

Such a switchgear enclosure is typically framed frame is installed in the upper part of the base plate that is firmly installed on the ground, the above-mentioned switchgear equipment as the door, side plate and roof plate are coupled to each other It can be safely protected and managed.

However, since earthquakes frequently occur in Korea in the near future, such a switchgear enclosure may not be considered safe from vibration caused by such an earthquake, so the seismic design of the enclosure is made so that the switchgear equipment can be safely and protected. The trend is losing.

In particular, "telecommunication equipment" in accordance with the contents of the "Building Guide for Seismic Design of Building Electrical Equipment" issued by the Korea Electrical and Technology Association (Korea Electrotechnical Standards Committee) and "Regulations on Technical Standards of Telecommunication Equipment" announced by the Institute of Telecommunications. According to the seismic test method (Radio Wave Research Laboratory Publication No. 2009-3), the design and construction for the fixing and fixing of electrical facilities such as faucets and power distribution rooms, etc. The seismic design must be made.

Here, the matters to be considered in the seismic design of the enclosure for the switchgear, the seismic load for the inertial force acting on the structure when the structure is vibrated by the earthquake, and the structure of the structure considering the vibration period and the vibration type applied to the structure The design should take into account both the dynamic characteristics, the ground characteristics, the ductility of the structure, and the importance of the structure.

Accordingly, the power distribution equipment and the power distribution equipment are installed in the enclosure of the existing switchgear using the base plate and the frame, and the power receiving equipment is mounted on a high damping rubber (HDR) to support it. It is installed, and distribution equipment is also installed on high damping rubber (HDR) to support it. That is, it is made by mounting the power receiving equipment or power distribution equipment on these high damping rubber in the state of fixing the high damping rubber using the base plate and the frame.

Accordingly, the high attenuation rubber is to prevent the damage or failure to the power receiving equipment and distribution equipment by effectively buffering and absorbing the vibration when the vibration caused by the earthquake.

In addition, the frame of the enclosure as described above is assembled by attaching a corner brace in the diagonal or inclined shape with respect to the vertical and horizontal frame connection portion to ensure the seismic design as the frame itself.

However, the conventional enclosure for the switchgear having the seismic design structure as described above, the seismic design is made by applying a high damping rubber, which is a type of seismic isolation device, the vibration isolator acts on the enclosure when the earthquake occurs. In order to prevent transmission, practically no direct seismic design of the frame of the enclosure has been made.

That is, when the enclosure is exposed to the vibration caused by the earthquake, the enclosure may be shaken forward or backward, or left, right and up and down depending on the characteristics of the seismic wave, or may be shaken in combination. As such, the vibration acting on the enclosure will only serve to reduce transmission to the switchboard, and as a result, the vibrations such as the fatigue fracture or shear or bending or twisting of the enclosure frame itself occur.

As such, when the deformation of the enclosure frame itself occurs, negligence may occur in protecting or fixing the internal switchgear. Therefore, a direct seismic design of the enclosure for the switchgear is urgently required.

In addition, the corner brace is applied to prevent the deformation of the frame itself is not applied to the front and rear door portion that requires the access or access of the operator is limited to only the side of the frame, so the front and rear directions to act on the frame Although it is stiff in vibration, it is vulnerable to vibrations in the left and right directions, and it is true that extensive seismic design cannot be achieved from vibrations having unpredictable directionality.

Therefore, there is an urgent need for an earthquake-proof or seismic isolation device capable of safely maintaining the front and rear directions as well as the left and right directions of the frame in the enclosure for the switchgear.

The present invention is to solve the problems as described above, the installation of separate seismic isolator on the front and rear frame of the frame in which the door is installed in the frame of the distribution panel, the seismic isolator is a horizontal frame perpendicular to each other And the first support and the second support are hinged to the vertical frame, respectively, and the first support and the second support are configured to be connected to the pin and the base is hinged to the intersection of the orthogonal horizontal frame and the vertical frame follow,

Switchgear panel equipped with the seismic isolator in the frame to minimize the deformation of the frame by actively supporting the vibration isolator in the left and right directions acting on the enclosure and the seismic load due to the seismic load It is an object of the present invention to provide an enclosure.

The present invention for achieving the object as described above, in the enclosure for the switchgear is equipped with a frame by the repetitive connection of the horizontal frame and the vertical frame on the base plate, the side plate and the roof plate and the door, The seismic isolation device is mounted on the horizontal frame and the vertical frame in which the door is mounted during the frame,

The base isolation device includes: a first support having one side hinged to a horizontal frame; A second support hinged at one end to a vertical frame orthogonal to the horizontal frame; One side end is hinged coupled to the intersection of the horizontal frame and the vertical frame, these first support, the second support and the base stand is composed of the other end hinged at the same time is configured to have a "Y" shape .

According to the present invention, when the seismic isolator having a "Y" shape is mounted on the front and rear frame portions of the frame of the frame in the enclosure for which the seismic isolation or seismic reinforcement is inadequate, the seat acting on the enclosure for the distribution panel is left. As the seismic isolator repeats compression and tension according to the vibration in the right direction, it increases the propulsion force of the frame in the enclosure. It can be achieved, and by the seismic isolation scheme for the frame within the enclosure to ensure a safe protection for the distribution equipment in the frame as well as to maintain a stable installation state for the enclosure for the distribution panel.

If necessary, at the intersection of the horizontal frame 11 and the vertical frame 12 is fixed to form a reinforcing bar on a diagonal to have a seismic structure.

At this time, the enclosure for the switchgear is that the doors 4 for opening and closing the interior are installed in the front and rear directions of the enclosure, respectively, for checking or repairing various devices built in the frame 10, and the doors described above. (4) is to be divided into the outer door and the inner door, if necessary, the front and rear sides of the frame 10 in which the door (4) is installed as described above has a problem that can not be installed on the diagonal reinforcement as described above I have it. This is because the door 4 should be opened to secure a space or a work space for the worker to go in and out, and in the case of a normal switchgear enclosure or a conventional switchgear enclosure, the door 4 is installed as described above. It is well known that the front and rear frames of the structure are very weak from vibrations acting in the left and right directions of the enclosure as the seismic or seismic design is not applied.

Accordingly, in the present invention, the seismic isolator is fixed to the front and rear frames of the enclosure in which the door 4 is installed with respect to the frame 10 as described above by fixing the seismic isolator 20 having a "Y" shape. (20) to ensure the design of the seismic isolation of the vibrations acting in the transverse direction, as well as to prevent the operator's entrance or work space even when opening the door (4) is very reasonable seismic isolation Design can be made.

The seismic isolator 20 as described above is fixedly installed by using the horizontal frame 11 and the vertical frame 12, one end of which is hinged to the horizontal frame 11 has a form inclined in the horizontal direction. Intersection between the first support 21 and the second support 22 and the horizontal frame 11 and the vertical frame 12 having a form inclined in the vertical direction by hinged one end to the vertical frame 12 One end is hinged to the part while the other end is made by the seismic stand 23 is hinged at the same time as the other end of the first support 21 and the second support 22 described above.

Accordingly, the first support 21, the second support 22 and the base stand 23 is hinged to the horizontal frame 11 and the vertical frame 12, while one end is hinged to each other at the same time the present invention The seismic isolator 20 is installed with a "Y" shaped coupling state in the front, rear direction of the door side of the switchgear enclosure.

Here, the seismic isolation device 20 is described as being installed at the lower right side when viewed from the front of the enclosure for the switchgear, but may be optionally installed at the upper right or upper left or lower, in this case, the horizontal frame 11 ) And the vertical frame 12 may be reversed, and if necessary, the seismic isolator 20 may be fixedly installed at one side up, down, or in a diagonal direction.

In addition, the first support 21, the second support 22 and the base stand 23 is hinged to the horizontal frame 11 and the vertical frame 12 through a separate corner coupling 30, respectively. As having a, the corner coupler 30 has a bending body 31 formed by bending both sides of the metal plate upwards, and one side of the bending body 31 has an integral or welded inclined connection plate 34. The side of the bending body 31 has a fastening hole 32, 32 'formed in the transverse direction and the inclined connecting plate 34 is formed through the hinge hole 33, respectively, It is.

Therefore, using the fastening holes 32, 32 'formed in the bending body 31 in a state in which the bending body 31 is placed in the horizontal frame 11 or the vertical frame 12 to be installed. What is necessary is to securely install the horizontal frame 11 and the vertical frame 12, and the first support 21 or the second support which is inclined to the inclined connecting plate 34 protruded obliquely from one side of the bending body 31. The ends of the support 22 and the base isolation 23 is to be fixed to have a hinge structure by pin coupling. Here, the horizontal frame 11 or the vertical frame 12 may be formed through a plurality of coupling holes corresponding to the fastening holes 32, 32 'formed in the bending body 31 in advance. .

Accordingly, one end of the first support 21, the second support 22 and the base isolation 23 is the horizontal frame 11 and the vertical frame 12 and the corner coupling hole 30 in the intersection thereof, respectively. The other end of the first support 21, the second support 22 and the base isolation 23 is connected to each other by pin coupling at the same time to be fixed and secured through the first support (3) 21) and the second support 22 and the base stand 23 is to maintain the organic coupling and fixing state.

In particular, the seismic stand 23 may be generally applied to a seismic means of various structures by means of steel bars or springs, urethane, rubber, etc., but in the present invention, a housing having a built-in spring 24 as a preferred embodiment ( By applying a structure in which the flow zones 26 and 26 'formed by splitting from both sides of the 25 are formed, the one side flow zone 26 is formed at the end of the first support 21 and the end of the second support 22. The hinge is coupled and the other end of the flow table 26 'is hinged through the corner coupling hole 30 at the intersection of the horizontal frame 11 and the vertical frame 12.

Here, the seismic stand 23 serves to cushion the compressive force or tensile force acting on the flow table 26 and 26 'by the built-in spring 24 to compress the compressive force to the flow table 26 and 26'. This action will narrow the distance between the flow zones 26 and 26 'as the springs 24 are compressed, and when the tension forces act on the flow zones 26 and 26' under compression, the flow zones 26 and 26 '. Will move away from each other.

Therefore, when vibration occurs from the side of the cabinet for the switchgear, the seismic isolator 20 may compress and tension the first support 21, the second support 2, and the seismic isolation 23 according to the direction of vibration. Through the vibration is to give a base isolation effect on the skeleton (10).

For example, as shown in FIG. 7, when the vibration in one direction is applied to the frame 10, the compressive force is applied to the first support 21 and the base stand 23 by transmission of a load acting on the frame 10. This action and the second support 22 is to prevent the twisting or inclination of the skeleton 10 while the tensile force acts on the contrary. In addition, as shown in FIG. 8, when the vibration in the other direction is applied to the frame 10, the tensile force is applied to the first support 21 and the base stand 23 by the transfer of the load acting on the frame 10. This will be the second support 22 is to prevent the twisting or inclination of the skeleton 10 while also acting the compressive force.

Therefore, when the vibration acting on the cabinet for the switchgear when the door 4 is viewed from the front is in the left and right directions, the first support 21 and the second support 22 and the surface constituting the seismic isolation device 20 described above. Since the shell 23 increases the resistance of the frame 10 to the vibration while repeatedly performing compression and tension, the enclosure for the switchgear according to the present invention can maintain a safe and solid installation state from vibration.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims.
