Description

Distributing board with heat sink

The present invention relates to a switchgear, and more particularly, to a switchgear having a heatsink to improve the lifespan of power equipment by more effectively dissipating heat generated therein.

BACKGROUND ART [0002] In general, a group power demanding place such as a school, a building, an apartment complex, and a factory is equipped with a switchboard 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 to convert 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 using insulating oil is to prevent this phenomenon because moisture or dust enters the insulation 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 sink for circulating insulating oil is installed outside the transformer unit to improve heat dissipation, thereby improving the heat dissipation effect.

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

That is, in order to effectively dissipate heat generated from the transformer mounted inside the switchboard according to the prior art to the outside, a plurality of air outlets are configured on the side of the enclosure case to introduce outside air and discharge the inside air, but the enclosure When the flow force of the air outside the enclosure case is greater than the flow force of the air due to the internal heat of the case, there is a problem in that the internal heat cannot be properly discharged through the air outlet. As a result, the lifespan of the transformer is shortened and the efficiency of the transformer is reduced.

The present invention has been devised to solve the above problems, by configuring heat sinks on the inside and outside of the enclosure body, respectively, and connecting each heat sink with a heat pipe to more effectively dissipate the heat generated inside the enclosure body. An object of the present invention is to provide a switchgear having a heat sink to improve the lifespan of the equipment.

A switchgear having a heat sink according to the present invention for achieving the above object includes an enclosure body having an internal space, a door selectively opened and closed from the side of the enclosure body, and an electric device installed in the internal space of the enclosure body And, a first heat sink configured in the interior of the enclosure body to collect heat generated therein, and connected to the first heat sink and configured on the outside of the enclosure body to collect heat collected from the first heat sink It characterized in that it comprises a second heat sink to radiate natural heat, and a heat pipe connecting the first heat sink and the second heat sink.
In addition, the guide part of the switchgear having a heat sink according to the present invention for achieving the above object is disposed in a connection portion between the first guide member and the second guide member, and the first fixing part in the process of opening and closing the door and a sloping plate in contact with a hinge or a second fixed hinge, wherein the distance between the first and second fixed hinges is in the range of 22 to 50% of the door width, and the door is closed in a direction in which the door is closed It further comprises a door closer for pushing the door, characterized in that it further comprises another guide part for guiding a pair of fixed hinges provided in the lower portion of the door.

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

First, each heat sink is configured inside and outside, and each heat sink is connected with a heat pipe to more effectively dissipate heat generated inside the enclosure body, thereby improving the lifespan of the power facility.

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 installation area of the overall enclosure body.

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

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

Fifth, structural rigidity can be increased by providing a pair of fixed hinges for the door.

Sixth, it is possible to effectively respond to an external force such as wind because the front surface of the door can be formed in a curved or inclined surface to disperse wind pressure.

Seventh, it is possible to maximize cooling efficiency while supplying clean air by purifying and supplying air flowing in 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 in advance the occurrence of dust and arcs and electric shock accidents due to the inflow of the fine dust of the iron component.

As shown in FIGS. 1 to 6 , the switchgear 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 . 120, the electric device 300 installed in the inner space of the enclosure body 110, and at least one side of the lower end of the enclosure body 110 to purify the outside air and iron contained in fine dust An air purifying unit 400 for supplying air to the interior of the enclosure body 110 by removing components, and a suction unit 500 configured on the upper portion of the enclosure body 110 to suck internal air upward; , an air outlet 600 configured on the upper side of the enclosure body 110 for discharging the air sucked through the suction unit 500 to the outside, and the enclosure body 110 being configured inside and generated from the inside A first heat sink 700 that collects the generated heat, and is connected to the first heat sink 700 and is configured on the outside of the enclosure body 110 to naturally dissipate the heat collected from the first heat sink 700 It comprises a second heat sink 800 that radiates heat, and a heat pipe 900 connecting the first heat sink 700 and the second heat sink 800 .

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

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

At this time, the door 120 is rotated by sliding transfer on the enclosure body (110). That is, unlike a sliding 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 rotation operation are simultaneously opened 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 body 110 is the main body of the switchgear equipped with power facilities such as VCB, VCS, VC, ACB, MCCB, PCB and reactor, inverter, capacitor, measurement and control module, SMPS, EMI filter and transformer therein. can be applied as

The enclosure body 110 has a substantially rectangular parallelepiped shape, left and right side surfaces, a rear surface, and upper and lower surfaces are formed, 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.

And the front opening 111 of the enclosure body 110 is provided with a door 120 for selectively shielding the opened space. In addition, a vibration isolator 200 or a vibration isolator may be provided on the bottom surface of the enclosure body 110 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 is rotated with sliding movement through the guide part 130 to open and close the door 120 . The door 120 is partly inserted into the enclosure body 110 while being opened in a closed state, and the other part protrudes outside the enclosure body 110 .

The door 120 is made to have a set thickness range, and is provided with a pad member 123 providing a heat insulation or sound absorption function 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, the door 120 is made of an insulating material and requires rigidity to cover the front surface of the enclosure body 110 , so it is preferably 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, electrical insulation, etc., so that it 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 stronger properties by mixing engineering plastics with glass fibers or carbon fibers, etc., may be composed of door materials. Of course, the door 120 may be basically implemented with a steel material of aluminum or stainless steel and a steel plate material.

Here, if there is a configuration made of a metal material rather than an insulating material among the components that the user can touch or grip on the door 120, although not shown in the drawing, a sensitive sensor (not shown) for sensing current or voltage Visual notification means (eg, LED, lamp, display panel, etc.) or audible notification means (eg, buzzer, speaker, bell, etc.) have.

And the door 120 is formed with a curved surface 124 or an inclined surface curved from the front to the rear of the enclosure body 110 . That is, when the front of the door 120 corresponding to the front of the enclosure body 110 is concavely bent in the inner direction of the enclosure body 110 when the door 120 is closed, a strong wind blows toward the door 120 It can also disperse wind pressure efficiently while supporting it.

In addition, since the front surface of the door 120 has the same curved surface or inclined surface in the vertical direction, and the same curvature is formed in the left and right directions of the door 120, an effect of increasing the rigidity in the vertical direction of the door 120 can 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 when a user (eg, an operator) comes into contact with the door 120 from the outside. it can be prevented

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

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

The fixing hinges 125 and 126 include a first fixing hinge 125 disposed adjacent to the outer edge of the door 120 and a second fixing hinge 126 disposed adjacent to the center of the door 120 . do. At least one or a plurality of bearings 127 may be provided in the first fixed hinge 125 and the second fixed hinge 126 , and the bearing 127 functions to reduce frictional force with the guide unit 130 . provides

In addition, the door 120 may maintain a fixed state on the enclosure body 110 and reduce frictional force in sliding transfer. Although not shown in the drawings, the door 120 is coupled to be slidably transported or rotatable 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 side 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 is in the range of 20 to 50% of the width of the door 120 (ratio 1:2 to 1: 5) can be done. More preferably, the overall width (including the distance between the fixed hinges) of the door 120 compared to the distance between the first and second fixing 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 resisting the wind pressure applied from the 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 regions or installation locations. In this way, the door 120 using the first and second fixed hinges 125 and 126 can safely withstand wind pressure from the front, and can prevent abrupt opening and closing of the door, thereby preventing a safety accident. .

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

The guide unit 130 is provided on the upper portion of the corner portion adjacent to the 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 part and the lower part, another guide part may be separately disposed at the lower part of the enclosure body 110 .

The guide part 130 is bent in an approximately "L" shape, and includes 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 . and 132. The shape of the guide part 130 is preferably made of the first guide member 131 and the second guide member 132 at an angle of at least 90° or more.

The first guide member 131 and the second guide member 132 have a transfer space 133 such that the first and second fixing hinges 125 and 126 are accommodated therein and transferred. 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.

An inclined plate 134 in contact with the 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 with the first fixing hinge 125 toward the second guide member 132 in the process of opening the door 120, and also the second fixing hinge 125 in the process of closing the door 120. 126 is interfered to face in the direction of 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 opening and closing process of the door 120 is smoothly performed on the guide part 130 . The swash plate 134 may be located on the transfer space 133 of the guide unit 130 or may be disposed outside the transfer space 133 .

The guide unit 130 includes one or a plurality of stoppers 135 that interfere with the first fixed hinge 125 or the second fixed hinge 126 in the transfer space 133 . The first stopper 135a of the stoppers 135 moves in the direction in which the door 120 closes to maintain the opening range (eg, about 1/3 or 2/3 opening point) set in the process of opening the door 120 . interfere with

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

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

The stopper 135 has a structure that protrudes into the transfer space 133 on the guide part 130, and elastically protrudes into the transfer space 133, or first and second fixed hinges 125, It is preferable to provide a structure that is pushed out of the transfer space 133 while in contact with the 126). In addition, the position of the stopper 135 may be changed according to the range in which the door 120 is mainly opened, and a larger 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 pushes by applying a force in the closing direction. Then, since a constant force is always applied in the closing direction of the door 120 , the stopper 135 may be disposed 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 portion (side or corner region) of the door 120, or may be provided to press any one of the pair of fixed hinges 125 and 126 .

A process of opening and closing the door 120 on the guide unit 130 will be described 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 opening direction, sliding transfer of the door 120 is performed first. At this time, the direction of the first fixing hinge 125 is changed from the first guide member 131 to the second guide member 132 while making contact with the inclined plate 134 .

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

When the second fixing hinge 126 passes the first stopper 135a while the door 120 is opened, the door 120 maintains the set opening range while maintaining the open state.

When the door 120 is fully opened by further pushing the door 120 , the fully opened state of the door may be maintained because the first fixing hinge 125 interferes with the second stopper 135b.

When the door 120 is closed again, the second fixing hinge 126 comes into contact with the swash plate 134 from the transfer space 133 of the second guide member 132 to the transfer space 133 of the first guide member 131 . direction is changed to After that, the process of closing the door 120 is performed in the reverse of the process of opening the door.

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

Comparing, for example, the installation area with the case where the existing switchgear door is installed through the door of the present invention is as follows.

In addition, the installation area according to the opening of the door 12 of the prior art is the same as the opening width of the door 12 is 1800 mm, and the length of the opened door 12 protruding to the outside of the enclosure body 11 is 900 mm, which is 16200 cm2. occupy

Therefore, it can be seen that the installation area required for opening and closing the door of the present invention is about 55.5% of the installation area required for opening and closing the door of the prior art, requiring almost half of the installation area. Of course, even if it is sufficiently taken into account that the insignificant dead space 112 is generated inside the enclosure body 110 of the present invention, the installation area can be reduced by at least 40% compared to the enclosure body 11 in which the conventional door 12 is installed. it can be
