Description

Distribution panel, connection panel, distribution panel, control panel equipped with seismic device}

The present invention relates to a switchgear, connection panel, distribution panel, and control panel equipped with an earthquake-resistant device that can protect against earthquake vibration by isolating vibrations from an earthquake.

Generally, electrical equipment for receiving, distributing, connecting, distributing, and controlling electricity is installed inside the enclosure.

In particular, electrical appliances installed inside the enclosure are vulnerable to earthquake vibrations, so when an earthquake occurs, there is a problem that they may be disconnected or short-circuited, causing a fire or malfunction, rendering them inoperable.

To solve this problem, a “control box with earthquake-resistant function” was previously disclosed in Korean Patent Publication No. 10-2300397 (announced on September 10, 2021).

The control box with the above-mentioned conventional earthquake resistance function has a hollow housing, a control panel is fixed to a fixing plate on the inner wall of the housing, and an earthquake prevention device is installed in which the fixing plate is connected to the inner wall of the housing with a first buffer member, By forming upper and lower plates that are symmetrical to each other, and attaching the lower part of the housing to the upper plate of the module box with the main damper formed between the upper and lower plates, vibration of the upper plate connected to the housing is alleviated by the second buffer member. This alleviates the vibration of the housing, and the first shock absorbing member of the earthquake-proof device installed in the housing prevents the vibration of the housing from being transmitted to the fixed plate, thereby preventing shock due to vibration from occurring on the control panel installed on the fixed plate. , it was possible to prevent various wires connected to the terminal block of this control panel from being deteriorated by vibration.

However, in a control box with a conventional earthquake-resistant function, the second buffer member cannot be installed when the control box is fixedly installed on the wall, and only the first buffer member cushions the control box. This not only reduces the effect of buffering earthquake vibrations, but also reduces the second buffer member. 1 Not only does the buffer member have the effect of cushioning only vibrations occurring in one direction, but there is also a problem in that it is not easy to install the fixing plate on the first buffer member.

In addition, as the number of electrical devices installed on the fixing plate increases, the load increases, causing downward sagging, and the first buffer member alone is insufficient to cushion the impact.

The present invention was devised to solve the above-mentioned problems. The problem to be solved by the present invention is to cushion the inner plate by the elastic force of the seismic isolation grommet according to the magnitude of the earthquake vibration, and to relative the inner plate or enclosure by the seismic isolation fastener. The purpose is to provide a switchboard, connection panel, distribution panel, and control panel equipped with an earthquake-resistant device that can minimize damage caused by an earthquake by minimizing the transmission of vibration while moving.

In addition, a seismic isolation member is installed on the first shaft, so that in the event of an earthquake causing the enclosure to shake forward and backward, the inner plate moves forward and backward, and the seismic isolating member provides cushioning to provide effective seismic isolation according to the direction of vibration.

The sagging prevention part may include a protruding support portion that protrudes from a portion supported by the enclosure so that the swing link can easily rotate by minimizing the contact area with the enclosure.

The seismic isolation grommet connects a first grommet portion supported on one side of the inner plate to isolate vibrations, a second grommet portion supported on the other side of the inner plate for seismic isolation, and the first grommet portion and the second grommet portion. 2. It may include a connection grommet for seismic isolation between the shaft portion and the inner plate.

According to the present invention, the inner plate in the enclosure is coupled by an elastic seismic isolation grommet to cushion relatively small vibrations, and when a relatively large vibration occurs, the inner plate is coupled by a seismic isolation fastener with a swing link and the inner plate is moved by its own weight. It adheres to the direction of gravity and only vibrates the enclosure, protecting the inner plate and the electrical devices installed on the inner plate from damage from earthquake vibration.

The earthquake-resistant device 130 may include a seismic isolation fastener 140 and a seismic isolation grommet 150.

The seismic isolation fastener 140 can connect the two to enable the enclosure 110 to swing relative to the inner plate 120 so that when the enclosure 100 is shaken by an earthquake, the inner plate 120 maintains its position by its own weight. there is.

Here, when an earthquake occurs, the enclosure 110 shakes because the enclosure 110 is relatively fixed to the floor or wall, and the inner plate 120 is attached to the inner plate 120 because it tries to stay in its current position due to its own weight. The enclosure 110 may shake due to vibrations from an earthquake.

The seismic isolation fastener 140 may connect the enclosure 110 and the inner plate 120 between the enclosure 110 and the inner plate 120 at a position corresponding to the grommet fixing hole 121 of the inner plate 120.

An example of the seismic isolation fastener 140 may include a first shaft portion 141, a second shaft portion 143, and a swing link 145.

The first shaft portion 141 may be fixedly installed on the surface of the enclosure 110, and the first shaft portion 141 is secured by installing a shaft fixing nut 141a on the inner surface of the enclosure 110.

The other end of the swing link 145 may be fixedly installed at the end of the second shaft portion 143.

Since the swing link 145 connects the first shaft 141 and the second shaft 143, the enclosure 110 rotates around the first shaft 141 or the second shaft 143 to prevent earthquakes. When shaken by vibration, the enclosure 110 swings relative to the inner plate 120 and the inner plate 120 maintains its position, thereby protecting the electrical equipment installed on the inner plate 120 (see FIG. 5).

And, at the end of the swing link 145 where the second shaft portion 143 is located, a sagging prevention portion 147 may be formed in a direction opposite to the direction in which the second shaft portion protrudes.

The seismic isolation fastener 140 may include a seismic isolation member 149.

The seismic isolation member 149 can isolate vibrations from an earthquake occurring in a direction perpendicular to the lateral direction of the enclosure 110, that is, in the front and rear of the enclosure 110.

The seismic isolation member 149 is installed on the first shaft portion 141 and supports the movement of the inner plate 120 in the first shaft portion 141 along the axial direction of the first shaft portion 141 by elastic force, thereby forming the enclosure 110. Seismic isolation can be performed against earthquakes occurring in front and behind.

Here, the front of the enclosure 110 refers to the open direction in which the opening and closing door of the enclosure 110 is installed.

The seismic isolating member 149 may include a first seismic isolating member 149a and a second seismic isolating member 149b.

The first seismic isolation member 149a is installed in the first shaft portion 141 between the outer end of the first shaft portion 141 and the swing link 145, and the second seismic isolation member 149b is located between the first shaft portion 141 and the swing link 145. The swing link 145, which is installed between the enclosure 110 and the swing link 145 and slides along the first shaft 141, is supported by elastic force to move the swing link 145 in the direction of the first shaft 141, that is, the housing ( 110) can isolate vibrations occurring in the front and rear.

Both the first seismic isolating member (149a) and the second seismic isolating member (149b) may be implemented as a compression coil spring having elastic force, or may be implemented as an elastic material such as rubber, but either of the first seismic isolating members (149a) may be implemented as a compression coil. One may be implemented as a spring, and the other may be implemented as an elastic body.

The earthquake-resistant device 130 may include a seismic isolation grommet 150.

The seismic isolation grommet 150 can isolate seismic vibration transmitted from the enclosure 110 to the inner plate 120 through the seismic isolation fastener 140 using elastic force.

The seismic isolation grommet 150 is inserted into the second shaft portion 143 and insulates the vibration of the second shaft portion 143 and the inner plate 120, and can also electrically insulate the inner plate 120 and the seismic isolation fastening portion 130. there is.

A shaft hole through which the second shaft portion 143 is inserted may be formed in the center of the seismic isolation grommet 150, and the seismic isolation grommet 150 may be formed of an elastic material having elastic force and electrical insulation.

The seismic isolation grommet 150 is provided with the inner plate 120 and The space between the enclosures 110 can be isolated by elastic force.

The seismic isolation grommet 150 may include a first grommet portion 151, a second grommet portion 153, and a connection grommet portion 155.

The first grommet portion 151 may support one side of the inner plate 120 around the grommet fixing hole 121, and the second grommet portion 153 may support the inner plate 120 around the grommet fixing hole 121. can support the other side.

The connection grommet part 155 connects the first grommet part 151 and the second grommet part 153, and is located in the grommet fixing hole 121 to support between the inner plate 120 and the second shaft part 143. can do.

The seismic isolation grommet 150 can isolate vibrations occurring in various directions because the first grommet part 151, the second grommet part 153, and the connection grommet part 155 are located around the grommet fixing hole 121. You can.

Since the seismic isolation grommet 150 is formed of an elastic material, the first grommet part 151 or the second grommet part 153 is forcibly crumpled and inserted so that the connection grommet part 155 is located in the grommet fixing hole 121. The seismic isolation grommet (150) can be forcibly inserted into the grommet fixing hole (121) and installed.

In addition, a cylindrical sleeve (not shown) may be inserted between the shaft hole of the seismic isolation grommet 150 and the second shaft portion 143 so that the second shaft portion 143 can easily rotate in the seismic isolation grommet 150. .

The earthquake-proof device 130 may include a separation prevention washer 170 and a sagging prevention clip 160.

The separation prevention washer 170 overlaps the first grommet part 151 or the second grommet part 153 located on the outside of the seismic isolation grommet 150, and the seismic isolation grommet 150 is positioned at the end of the second shaft part 143. 2 It is possible to prevent separation from the shaft portion 143.

As in the embodiment, the separation prevention washer 170 overlaps the first grommet portion 151 located on the outer surface of the inner plate 120, and the end of the second shaft portion 143 moves downward due to the load of the inner plate 120. When struck, the first grommet portion 151 is elastically deformed, thereby preventing it from escaping through the head of the second shaft portion 143.

The circumference of the separation prevention washer 170 may have a larger circumference than the circumference of the head of the grommet fixing hole 121 and the second shaft portion 143.

The sagging prevention clip 160 can prevent the end of the second shaft 143 from sagging downward due to the load of the inner plate 120.

The anti-sag clip 160 has one end supporting the lower part where the second shaft portion 143 is connected to the swing link 145, and the other end supporting the lower end of the grommet fixing hole 121 of the inner plate 120. 2 It is possible to prevent the end of the shaft portion 143 from sagging toward the bottom of the swing link 145.

The anti-sag clip 160 is formed in an "ㅅ" shape with both sides widening toward the bottom, and a fitting groove that is inserted into the second shaft portion 143 may be formed in the lower part of the anti-sag clip 160.

Here, when the inner plate 120 sags downward due to the weight of the electric device installed on the inner plate 120, the inner plate 120 is separated from the second shaft portion 143, or the first shaft portion 141 sags downward together. Since the operation of the swing link 145 may not be smooth, the sagging prevention clip 160 pushes the lower part of the swing link 145 and the lower part of the inner plate 120 against each other by elastic force. By supporting, the second shaft portion 143 can be prevented from sagging due to the load of the inner plate 120.

Let us explain the actions and effects between each component described above.

The switchboard, connection panel, distribution board, and control panel 100 equipped with an earthquake-resistant device according to an embodiment of the present invention are equipped with an inner plate 120 on which electric devices are installed inside the enclosure 110, and the enclosure 110 and the inner plate are installed. (120) are connected to each other by an earthquake-resistant device (130) that performs seismic isolation when an earthquake occurs.

The earthquake-resistant device 130 is coupled to the enclosure 110 and the inner plate 120 by a plurality of seismic isolation fastening parts 140 installed at each corner of the inner plate 120, and the seismic isolation fastening part 140 includes a seismic isolation grommet ( 150) is installed to isolate relatively small vibrations by the seismic isolation grommet (150).

The seismic isolation fastener 140 is fixed to the shaft fixing nut 141a fixed to the first shaft portion 141 to the housing 110, and an inner plate 120 is provided at a portion spaced apart from the lower part of the first shaft portion 141. The second shaft portion 143 that is coupled is positioned, and the first shaft portion 141 and the second shaft portion 143 are connected by a swing link 145 that swings one or both of them to each other.

And on the surface of the swing link 145 facing the enclosure 110, a sagging prevention portion 147 is formed to protrude to prevent the swing link 145 from sagging around the first shaft portion 141.

A protruding support portion 147a may be formed on the sagging prevention portion 147 to minimize the contact area with the enclosure 110 and ensure the operation of the swing link 145.

Meanwhile, a seismic isolation member 149 is installed in each seismic isolation fastening part 140 to isolate the vibration of an earthquake occurring in the front and rear of the enclosure 110 by the seismic isolation member 149, and the seismic isolation member 149 is the first It is composed of a seismic isolating member 149a and a second seismic isolating member 149b. The first seismic isolating member 149a is the head of the first shaft portion 141 located outside the inner plate 120 from the first shaft portion 141. It is located between the inner plate 120 and the inner plate 120, and the second seismic isolation member 149b is installed to be positioned between the inner plate 120 and the enclosure 110 in the first shaft portion 141.

Both the first seismic isolating member 149a and the second seismic isolating member 149b may be formed of an elastic body having elastic force.

A seismic isolation grommet 150 for seismically isolating the inner plate 120 by elastic force is fixedly installed on the second shaft portion 143 by inserting it into the grommet fixing hole 121 in the form of an interference fit.

The seismic isolation grommet 150 is configured to connect the flange-shaped first grommet part 151 and the second grommet part 153 by a connecting grommet part 155, and the first grommet part 151 is an inner plate. is supported on one side, the second grommet portion 153 is supported on the other side of the inner plate, and the connection grommet portion 155 is inserted into the grommet fixing hole 121 and positioned.

A shaft hole is formed through the center of the seismic isolation grommet 150, and the second shaft portion 143 is installed through the shaft hole.

In addition, a sleeve can be inserted into the shaft hole so that the seismic isolation grommet 150 can easily rotate in the second shaft portion, and the shaft hole is expanded between the head portion of the second shaft portion 143 and the first grommet portion 151. As this happens, a separation prevention washer 160 is installed to prevent it from falling off.

And an anti-sag clip 160 is installed between the swing link 145 and the inner plate 120 where the second shaft portion 143 is located, and the anti-sag clip 160 is a spaced fit with an open bottom. The second shaft portion 143 is installed in the groove 161, one end of the anti-sag clip 160 is supported on the swing link 145, and the other end is supported on the inner plate 120 to form a swing link 145. ) and the inner plate 120 are pushed against each other by elastic force to prevent the second shaft portion 143 from sagging due to the load of the inner plate 120.

In the switchboard, connection panel, distribution panel, and control panel 100 equipped with an earthquake-resistant device according to an embodiment of the present invention configured in this way, when an earthquake of relatively small vibration occurs, the swing link 145 does not operate, and the inner plate 120 ) and the first shaft portion 141, the seismic isolation grommet 150 insulates the vibration between the enclosure 110 and the inner plate 120, so that the electric device connected to the inner plate 120 is disconnected due to vibration. This can prevent this from occurring or being damaged.

On the other hand, when an earthquake occurs with a relatively large vibration that causes the enclosure 110 to shake left and right, the inner plate 120 is moved by the first shaft 141, the second shaft 143, and the connecting link 145. Because it is installed as if hanging from the enclosure 110, when the enclosure 110 is shaken by vibration, the inner plate 120 tries to maintain its position in the direction of gravity due to its own weight, weight, and the weight of the installed electric device, so the enclosure ( By performing seismic isolation in a way that only 110) is shaken and the inner plate 120 maintains its current position, damage to the inner plate 120 and the electrical devices installed on the inner plate 120 can be prevented.

In addition, when an earthquake occurs with a relatively large vibration that causes the enclosure 110 to shake forward and backward, the enclosure 110 shakes forward and backward with respect to the inner plate 120, causing the first seismic isolation member 149a and the second seismic isolation member 149a. Since the impact of the inner plate 120 is cushioned and seismically isolated by the member 149b, the enclosure 110 and the inner plate 120 vibrate together to prevent damage to the inner plate 120 and the electrical devices installed on the inner plate 120. can do.

Therefore, the switchboard, connection panel, distribution panel, and control panel 100 equipped with the earthquake-resistant device according to the embodiment of the present invention isolate relatively small vibrations by the elastic force of the seismic isolation grommet 150, and isolate relatively large vibrations by seismic isolation fasteners. There is an advantage in that disconnection or damage to electrical equipment due to earthquake vibration can be minimized by seismic isolation by allowing the part 140 to swing and move forward and backward between the inner plate 120 and the enclosure 110.

In addition, the first shaft portion 141 and the second shaft portion 143 spaced apart from the first shaft portion 141 are connected to each other by the swing link 145, so that the enclosure 110 swings relative to the inner plate 120, By minimizing the transmission of earthquake vibrations shaking in the side direction of the enclosure 110 to the inner plate 120, damage to the electrical device coupled to the inner plate 120 can be minimized.

In addition, a first seismic isolating member 149a and a second seismic isolating member 149b are installed on the first shaft 141 to cushion the vibration of an earthquake shaking the enclosure 110 forward and backward, thereby providing an electrical mechanism coupled to the inner plate 120. Damage can be minimized.

In addition, the swing link 145 is supported on the enclosure 110 by the sagging prevention portion 147, which not only prevents the first shaft portion 141 from sagging downward due to the weight of the inner plate 120, but also prevents the swing link 145 from sagging downward. A sagging prevention clip 160 is installed between the link 145 and the inner plate 120 to prevent the second shaft portion 143 from sagging downward due to the weight of the inner plate 120.
