Description

Distribution board with heat sink

The present invention relates to a switchboard, and in particular, to a switchboard provided with a heat sink to improve the life of the power equipment by more effectively dissipating heat generated inside.

In general, collective power consumers such as schools, buildings, apartment complexes, and factories are equipped with switchboards in order to obtain the power required by each of them. This switchgear is equipped with a transformer, a switch device, and other safety devices in order to transform the extra-high voltage supplied from the substation into an appropriate low-voltage commercial voltage.

Here, the transformer has a structure in which an iron core is wound around a primary coil connected to a power source and a secondary coil connected to a load in order to maintain a constant power by changing an applied voltage to a higher or lower voltage.

That is, the transformer includes a transformer unit composed of a primary coil, a secondary coil, and an iron core, and the transformer unit is placed in a case and filled with insulating oil. The reason for the use of insulating oil is to prevent this phenomenon because moisture or dust enters the insulating material of the coil and lowers the dielectric strength, and to dissipate the heat generated from the iron core or coil by convection or radiation of the oil.

On the other hand, in a large-capacity transformer, a heat dissipation plate for circulating insulating oil outside the transformer unit is installed to improve heat dissipation in order to improve heat dissipation.

However, the switchgear according to the prior art as described above has the following problems.

In other words, in order to effectively dissipate heat generated from the transformer mounted inside the switchboard according to the prior art, a plurality of air outlets are configured on the side of the enclosure case to inflow outside air and discharge the air inside the enclosure. When the flow force of air outside the enclosure case is greater than the flow force of air caused by the heat inside the case, there is a problem in that the inside heat cannot be properly discharged through the air outlet. This shortened the life of the transformer and caused a decrease in the efficiency of the transformer.

The present invention was conceived to solve the above problems, and by configuring heat sinks inside and outside the enclosure body, and connecting each heat sink with a heat pipe, the heat generated inside the enclosure body is more effectively dissipated and power The purpose of this is to provide a switchboard equipped with a heat sink to improve the life of the equipment.

The switchboard having a heat sink according to the present invention for achieving the above object includes an enclosure body having an interior space, a door selectively opened and closed from the side of the enclosure body, and an electric device installed in the interior space of the enclosure body. And, a first heat sink configured inside the enclosure body to collect heat generated therein, and a first heat sink connected to the first heat sink and configured outside the enclosure body to collect heat collected from the first heat sink. It characterized in that it comprises a second heat sink that radiates naturally and a heat pipe connecting the first heat sink and the second heat sink.

The switchgear provided with a heat sink according to an embodiment of the present invention has the following effects.

First, by configuring heat sinks inside and outside each, and connecting each heat sink with a heat pipe, heat generated inside the enclosure body can be more effectively dissipated, thereby improving the life of the power equipment.

Second, since the door is rotated and opened and closed with sliding transfer on the enclosure body, the area required for opening the door can be reduced, thereby reducing the overall installation area of the enclosure body.

Third, since the door is made of an insulating material, it is possible to prevent the user from being exposed to safety accidents.

Fourth, it is possible to guide and fix the sliding movement of the door on the guide part, so that the degree of opening of the door can be maintained at a set angle.

Fifth, the door may be provided with a pair of fixing hinges to increase structural rigidity.

Sixth, since the front of the door can be formed in a curved or inclined surface to distribute wind pressure, it is possible to effectively respond to external forces such as wind.

Seventh, it is possible to maximize cooling efficiency while supplying clean air by purifying and supplying air introduced from the outside to the side of the enclosure body with a triple filter.

Eighth, since the iron component contained in the fine dust in the air flowing into the body can be filtered, it is possible to prevent the occurrence of dust, arcs, and electric shock accidents due to the introduction of the fine dust of the iron component.

The switchboard 100 having a heat sink according to the present invention includes an enclosure body 110 having an internal space and a door selectively opened and closed from the side of the enclosure body 110 as shown in FIGS. 1 to 6. (120), the electric device 300 installed in the inner space of the enclosure body 110, and iron contained in the fine dust while being configured on at least one side of the lower end of the enclosure body 110 to purify external air An air purification unit 400 for supplying air to the interior of the enclosure body 110 by removing components, and a suction unit 500 configured on an upper portion of the enclosure body 110 to inhale the air therein, , An air outlet 600 configured on the upper side of the enclosure body 110 to discharge the air sucked through the suction unit 500 to the outside, and the enclosure body 110 is constructed and generated from the inside. The first heat sink 700 to collect the heat generated, and connected to the first heat sink 700 and configured on the outside of the enclosure main body 110 to naturally generate the heat collected from the first heat sink 700. It comprises a second heat sink 800 to radiate heat, and a heat pipe 900 connecting the first heat sink 700 and the second heat sink 800 to each other.

Here, a door 120 selectively shielding the opening 111 of the front of the enclosure body 110, and a guide unit 130 provided in the enclosure body 110 to guide opening and closing of the door 120 are further provided. Includes.

On the other hand, in the embodiment of the present invention, the switchgear is described as one embodiment, but the present invention is not limited thereto, and any one of a high-voltage switchboard, a low-voltage switchboard, a distribution board, a solar connection panel, an inverter, a motor control panel and an ESS may be employed .

At this time, the door 120 is rotated on the enclosure body 110 by sliding transfer. That is, unlike a casement door that is opened and closed only by rotation like a general door or a sliding door that is opened and closed only by sliding, the sliding operation and the rotational operation are simultaneously accompanied and open and closed.

The enclosure body 110 may be applied as any one of a high-voltage switchboard, a low-voltage switchboard, a distribution board, a junction box, a motor control panel, and an ESS according to the structure or type of facilities installed therein. For example, the enclosure main body 110 is the main body of a switchboard having power facilities such as VCB, VCS, VC, ACB, MCCB, PCB and reactor, inverter, capacitor, measurement control module, SMPS, EMI filter, and transformer. Can be applied as

The enclosure body 110 has a substantially rectangular parallelepiped shape, and has left and right side surfaces, a rear surface and an upper surface, and an open opening is formed in the front surface. Of course, the shape of the enclosure body 110 is not limited thereto, and may be formed in a polyhedral or spherical shape including a rectangular parallelepiped.

In addition, a door 120 is provided in the front opening 111 of the enclosure body 110 to selectively shield the opened space. In addition, a vibration isolator 200 or a seismic isolator may be provided on the bottom of the enclosure body 110 so as to respond to an external force such as an earthquake between the installation surface (eg, the ground).

As an example, the door 120 is provided as a pair to face each other so as to shield the front surface of the enclosure body 110 from both sides, and may be provided as a single door. In addition, a door lock 121 may be provided on the door 120.

The door 120 rotates along with the sliding movement through the guide part 130 to perform an opening/closing process. When the door 120 is opened in a closed state, a part of the door 120 is inserted into the enclosure body 110, and the other part protrudes outside the enclosure body 110.

The door 120 is made to have a set thickness range, and a pad member 123 for providing a heat insulation or sound absorption function is provided therein. For example, the door 120 may have a thickness of about 100 mm, and the pad member 123 may be embedded therein. At this time, since the door 120 is made of an insulating material and requires rigidity to cover the front surface of the enclosure body 110, it is preferable to be made of engineering plastic.

These engineering plastics are excellent in strength and elasticity, as well as impact resistance, abrasion resistance, heat resistance, cold resistance, chemical resistance, and electrical insulation, and thus can be applied as a door material of the large-scale enclosure body 110. In addition, fiber reinforced plastics (FRP), a composite material that exhibits more powerful properties by mixing engineering plastics with glass fiber or carbon fiber, may be made of the door material. Of course, the door 120 may be basically made of aluminum, stainless steel, or steel made of a steel plate.

Here, if there is a configuration made of a metal material other than an insulating material among the configurations that the user can touch or grip on the door 120, a sensitization sensor (not shown) that senses current or voltage, although not shown in the drawing, is provided. A visual notification means (e.g., LED, lamp, display panel, etc.) or an audible notification means (e.g., buzzer, speaker, bell, etc.) may be provided so that the user can transmit a warning message about access or contact prohibition have.

In addition, the door 120 has a curved surface 124 or an inclined surface curved from the front to the rear of the enclosure body 110. That is, when the door 120 is closed, the front of the door 120 corresponding to the front of the enclosure body 110 is bent in a concave direction in the interior of the enclosure body 110, so that a strong wind blows toward the door 120 Edo can be dispersed while supporting the wind pressure efficiently.

In addition, since the front of the door 120 is made of the same curved or inclined surface in the vertical direction and has the same curvature in the left and right directions of the door 120, the effect of increasing the rigidity in the vertical direction of the door 120 can also be expected. have. In addition, since the door 120 is made of an insulating material, a potential difference does not occur with the power equipment inside the enclosure body 110, so that a safety accident occurs even if a user (for example, an operator) contacts the door 120 from the outside. Can be prevented.

In addition, although not shown in the drawings, the curved surface 124 or the inclined surface of the door 120 may be formed of a convex curved surface or an inclined surface protruding outward from the front of the enclosure body 110, and the enclosure body 110 The door 120 may have a curved or inclined surface structure corresponding to a curved surface or an inclined surface of the door 120 in the lower region or the upper region of the door 120.

A pair of fixing hinges 125 and 126 are provided on the upper and lower surfaces of the door 120 to limit the transfer range through the guide unit 130. Of course, depending on the size or weight of the door, only one of the upper or lower surfaces of the door 120 may be provided with a fixing hinge.

The fixing hinges 125 and 126 include a first fixing hinge 125 disposed adjacent to an outer edge of the door 120 and a second fixing hinge 126 disposed adjacent to the center of the door 120 do. The first fixing hinge 125 and the second fixing hinge 126 may be provided with at least one or a plurality of bearings 127, and the bearing 127 has a function of reducing frictional force with the guide part 130 Provides.

In addition, the door 120 may maintain a fixed state on the enclosure body 110 and may reduce frictional force during sliding transfer. Although not shown in the drawings, the door 120 is coupled so as to be capable of sliding transfer or rotation around the opening 111 of the enclosure body 110 at least. Here, the first and second fixing hinges 125 and 126 may be made of a metal material separate from the door 120, and may be made of the same material as the door for insulation. In addition, the door lock 121 provided on the front of the door 120 may also be made of the same material as the door 120 or at least an insulating material for insulation.

And on one door 120, the distance between the first fixed hinge 125 and the second fixed hinge 126 ranges from 20 to 50% with respect to the width of the door 120 (at a ratio of 1:2 to 1: 5). More preferably, the total width of the door 120 (including the distance between the fixed hinges) compared to the distance between the first and second fixed hinges 125 and 126 may be made in a ratio of 1:3. The ratio of 1:3 can effectively reduce the dead space generated inside the enclosure body 110 while enduring the wind pressure applied in front of the door 120.

Here, the ratio of the width of the door 120 to the distance between the first and second fixing hinges 125 and 126 may be changed in consideration of characteristics according to an area or an installation location. In this way, the door 120 using the first and second fixing hinges 125 and 126 can safely withstand wind pressure from the front, and can prevent sudden door opening and closing, thereby preventing safety accidents. .

The opening and closing operation of the door 120 on the enclosure body 110 is guided by the guide unit 130.

The guide part 130 is provided on an upper portion of a corner portion having an adjacent front and side surfaces of the enclosure body 110. Of course, in a structure in which the door 120 is fixed at both the upper and lower portions, another guide portion may be separately disposed under the enclosure body 110.

The guide part 130 is bent in an approximately “L” shape, and a first guide member 131 adjacent to the front surface of the enclosure body 110 and a second guide member adjacent to a side surface of the enclosure body 110 (132) It is preferable that the shape of the guide part 130 is formed at an angle of at least 90° or more between the first guide member 131 and the second guide member 132.

The first guide member 131 and the second guide member 132 are provided with a transfer space 133 so that the first and second fixing hinges 125 and 126 are accommodated and transferred therein. At this time, the transfer space 133 inside the first guide member 131 and the second guide member 132 is formed to communicate with each other.

A swash plate 134 in contact with a fixed hinge is provided at a connection portion between the first guide member 131 and the second guide member 132. The swash plate 134 interferes so that the first fixing hinge 125 faces the second guide member 132 in the process of opening the door 120, and the second fixing hinge ( The interference 126 is directed toward the first guide member 131. That is, the swash plate 134 comes into contact with the first and second fixing hinges 125 and 126 so that the process of opening and closing the door 120 is smoothly performed on the guide unit 130. The swash plate 134 may be located on the transfer space 133 of the guide part 130 or may be disposed outside the transfer space 133.

The guide part 130 includes one or a plurality of stoppers 135 interfering with the first fixing hinge 125 or the second fixing hinge 126 in the transfer space 133. Among the stoppers 135, the first stopper 135a is in the direction in which the door 120 is closed so as to maintain an open range (eg, about 1/3 or 2/3 open point) set in the process of opening the door 120. Interferes.

For example, when the door 120 passes through the first stopper 135a while the user opens the door about 2/3 (when the fixing hinge passes after contacting the stopper), the door 120 is closed in the direction in which the door 120 is closed. 1 Because it interferes with the stopper (135a), about 2/3 of the open state can be maintained.

In addition, a second stopper 135b among the stuffers 135 may be further provided on the guide unit 130 to maintain the door 120 in a completely open state. For example, when the door 120 is completely opened, the first fixing hinge 125 is disposed to be adjacent to the end of the second guide member 132, and the second stopper 135b at this position on the guide part 130 When is provided, it is possible to maintain the completely open state of the door 120.

The stopper 135 has a structure protruding into the transfer space 133 on the guide part 130, and resiliently protrudes into the transfer space 133, or the first and second fixing hinges 125, It is preferable that it is provided in a structure that is pushed to the outside of the transfer space 133 while contacting the 126. Further, the position of the stopper 135 may be changed according to a range in which the door 120 is mainly opened, and a greater number of stoppers may be provided according to the degree of opening of the door 120.

The door 120 may be provided with a door closer (not shown) that exerts a force in the closing direction. Then, since a constant force always acts in the closing direction of the door 120, the stopper 135 may be arranged to interfere only in the closing direction of the door 120. Although not shown in the drawings, such a door closer may be provided to press a part of the door 120 (side or edge area), or may be provided to press any one of a pair of fixing hinges 125 and 126. .

In this way, a process of opening and closing the door 120 on the guide unit 130 is as follows.

First, when the user grips the door 120 handle (not shown) or the door lock 121 and pushes the door 120 in the open direction, the sliding transfer of the door 120 is performed first. At this time, the first fixing hinge 125 is in contact with the swash plate 134 and changes its direction from the first guide member 131 to the second guide member 132.

As the first fixing hinge 125 enters the transfer space 133 of the second guide member 132, the door 120 rotates simultaneously with the sliding transfer. At this time, a dead space 112 is generated as the door 120 slides and rotates within the enclosure body 110, which is a negligible value compared to the total volume inside the enclosure body 110. In addition, it is possible to adjust the arrangement of power equipment inside the enclosure body 110 so as not to interfere with the dead space 112.

When the door 120 is opened and the second fixing hinge 126 passes the first stopper 135a, the door 120 is maintained in an open state while maintaining the set open range.

In addition, when the door 120 is pushed further to be completely opened, the first fixing hinge 125 interferes with the second stopper 135b, so that the door can be maintained in a completely open state.

When the door 120 is closed again, the second fixing hinge 126 contacts the swash plate 134 and the transfer space 133 of the first guide member 131 from the transfer space 133 of the second guide member 132 The direction is switched to. After that, the process of closing the door 120 is the opposite of the process of opening the door.

In the first heat sink 700 or the second heat sink 800, a plurality of radiating fins 720 are formed around the support member 710, and a fixing hole 730 is formed at the lower edge of the radiating fins 720. Consists of. The support member 710 on which the radiating fins 720 are formed is fixed to the fixing member 740 attached to the inner surface of the enclosure body 110 through the fixing hole 730.
