Description
Distribution board with variable modules utilizing internal bulkheads
[0001] The present invention relates to a switchboard having a variable module utilizing an internal bulkhead, and more specifically, to a switchboard having a variable module that changes the internal bulkhead structure of the switchboard in a modular manner.
[0002] As is well known, a distribution panel is a device used to monitor, control, and protect a power system.
[0003] A distribution board can be composed of unit devices (e.g., circuit breakers, grounding switches, protective relays, etc.), a support structure for attaching and supporting the unit devices, and a bus bar or bus for connecting or connecting the unit devices.
[0004] Depending on the insulation medium, these switchboards are classified into air-insulated switchboards, solid-insulated switchboards, and gas-insulated switchboards.
[0005] Additionally, the distribution board may be configured with a plurality of panels that are typically arranged transversely (e.g., left-right). For example, the distribution board may include panels 1 through 5. The first panel receives power from the upper grid, the second panel supplies power to the consumers, the third and fourth panels monitor the power, and the fifth panel may be reserved for other consumers.
[0006] In addition, since a number of electrical equipments are installed in a modular manner in conventional distribution panels, the interior of the distribution panel's enclosure must be divided into several compartments, and these compartments are formed through a number of frames and plates. For the convenience of manufacturing, most of the frames and plates used in the enclosure are made by bending, drawing, and punching metal sheets.
[0007] Therefore, in the case of existing distribution panels, the bulkheads that separate the internal space of the enclosure are manufactured in the form of a single box, so each can be viewed as an individual product with a bulkhead structure built in based on the standard.
[0008] For example, in the case of low-voltage distribution boards with a rated voltage of 1000 V or less, since there is no design definition for the internal bulkhead structure, the entire board is designed as a single box, which causes the problem of having to design each internal bulkhead structure individually on a single platform.
[0009] The structure of a distribution panel according to the prior art is schematically described below with reference to FIGS. 1 and 2.
[0010] Figure 1 is a front view showing a distribution panel structure according to conventional technology.
[0011] Fig. 2 is a perspective view showing the internal structure of a distribution panel section according to the prior art.
[0012] Referring to FIGS. 1 and 2, it is composed of an outer case (10), a mother unit (20), a function unit (30), a terminal unit (40), and a bulkhead (50) that blocks the internal space of the outer case (10).
[0013] The above-mentioned mother line (20) is a power supply that transmits power to individual loads or adjacent sections, and may be required to be separated in spaces accessible to people to prevent personal injury.
[0014] In addition, the above bulkhead (50) is manufactured in the form of a box that cannot be separated and removed to change the structure of the inner wall by banding, drawing, and punching a metal plate on the outer case (10).
[0015] The above mother unit (20) is arranged on the side of the functional unit (30) and is configured to supply power to each functional unit (30).
[0016] In addition, the above functional unit (30) includes a bus bar (31) connected to the mother line (20) on the left side of the distribution panel.
[0017] The above bus bar (31) connects the mother unit (20) and the functional unit (30), passes through the left wall of the functional unit (30), and a partition made of an insulating material is assembled on this wall to satisfy the insulation distance.
[0018] In addition, on the right side of the above-mentioned functional unit (30), a bus bar (31) connected to the rear side of the panel is fastened, and the bus bar (31) passes through the rear wall of the functional unit (30) and passes through the terminal unit (40).
[0019] Additionally, a partition wall (50) made of insulating material is assembled at the point where the bus bar (31) passes through the rear wall.
[0020] In addition, the terminal unit (40) installed on the rear side is provided with a partition (50) for separating each of the functional units (30).
[0021] The distribution board according to the prior art having such a configuration is configured so that the casing constituting the outer box (10) is composed of all the walls constituting the functional unit, so that the removal of the bulkhead for changing the structure of the inner wall is impossible.
[0022] This configuration has a disadvantage in that a part of the wall that modularizes the functional unit (30), i.e., the bulkhead (50), is configured so that it cannot be detached or separated, making it impossible to serialize or change the design of the internal bulkhead on the same platform.
[0023] In order to solve the above problems, the present invention provides a distribution board including an outer case, a bus bar arranged on one side of the outer case, a plurality of functional units arranged vertically apart inside the outer case, a terminal unit connected to a main circuit of the functional unit, and a partition wall that divides the internal space of the outer case to separately store the functional units, wherein the partition wall is configured to be detachable so that the design of the internal partition module can be varied, thereby allowing the internal partition structure of the distribution board to be changed in a modular manner, thereby facilitating the design variation of the internal partition wall for each grade to suit the customer's requirements.
[0024] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the proposed embodiment belongs from the description below.

[0096] That is, the above-mentioned bulkhead section (500) is designed in the form of a box in which the bulkheads that divide the internal space of a conventional distribution board are designed so that the bulkheads cannot be separated and assembled separately, thereby improving the problem of not being able to additionally assemble or separate the bulkheads of the desired shape by the customer. In this way, the internal bulkheads can be easily attached and detached to the frame using fastening means such as bolts or nuts, thereby conveniently changing the structure of the internal space of the outer box.
[0097] Accordingly, the bulkhead (500) includes a longitudinal frame (510) arranged vertically to the outer case (100) and an internal bulkhead (600) detachably fastened to the frame (510) to separate the internal space.

[0108] Accordingly, the frame (510) forms a receiving portion of a certain space surrounded by a support surface (511), a first side plate (512a), and a second side plate (512b).
[0109] The above frame side plate (512) is formed to protrude vertically at the corner of the support surface (511) and is configured to connect the frame (510) to the outer case (100).
[0110] In addition, the frame side plate (512) may include a first side plate (512a) formed by bending at the upper and lower edges of the support surface (511) and a second side plate (512b) formed by bending vertically at the side edge of the support surface (511).

[0114] Specifically, the internal bulkhead (600) forms a bulkhead that separates the internal space of the outer case (100), and can be easily attached to and detached from the frame (510) using a fastening means such as a bolt.
[0115] In addition, the internal bulkhead (600) is installed in a space between functional units (300), between functional units (300) and terminal units (400), or between functional units (300) and a mother unit (200), thereby forming modules of various specifications surrounding the functional units (300), terminal units (400), and mother unit (200).
[0116] In addition, the internal bulkhead (600) may include a plate (610) fastened to the frame (510) and a casing (620) in the shape of a body that covers the terminal unit (400).

[0123] Accordingly, the first plate (611) is formed in a rectangular plate shape having an area similar to or larger than the cross-sectional area of the functional unit (300) as shown in FIG. 7.
[0124] In addition, the first plate (611) includes a connecting member (611a) formed by bending at an edge of the first plate (611) and a plurality of ventilation holes (611b) that pass through the first plate (611) to a certain length.
[0125] The above-mentioned connecting member (611a) is a plate-shaped member formed by bending at the corner of the first plate (611), and is configured to fix the first plate (611) to the outer case (100) and the frame (510) after the first plate (611) is inserted into the space between the functional units (300).
[0126] Accordingly, the above-mentioned connecting member (611a) is provided with a plurality of connecting member fastening holes (611c) into which fastening means are inserted.
[0127] That is, the above-mentioned connecting member (611a) is configured to connect the first plate (611) to the frame (510) while the first plate (611) is horizontally inserted into the outer case (100), and is connected by a connecting means while in contact with the connecting portion (511a) of the frame (510).

[0193] Below, the structure of the internal bulkhead required in the distribution panel is explained.
[0194] Figure 11 is a diagram showing a basic model of the internal bulkhead structure of a distribution panel.
[0195] Fig. 11(a) corresponds to a basic model of the internal bulkhead structure of a distribution panel, and is a structure that is extremely rarely used in practice, with no internal bulkhead (600) between the mother unit (200), the functional unit (300), and the terminal unit (400).
[0196] Figure 11(b) can be divided into the 2a structure (Form2a) and the 2b structure (Form2b).
[0197] In the case of the 2a structure (Form2a), the group of functional units (300) is separated from the mother unit (200), and the group of functional units (300) is separated from the terminal unit (400). In addition, the terminal unit (400) is not separated from the mother unit (200).
[0198] Accordingly, the second a structure is formed by fastening the first plate (611) and the second plate (612) to the frame (510) to form an internal bulkhead.
[0199] In the case of the 2b structure (Form2b), the group of the bus part (200) and the functional unit (300) are separated, as in the 2a structure (Form2a), but the functional unit (300) and the terminal unit (400) are not separated. However, since the bus part (200) and the functional unit (300) are separated, when the power of the functional unit (300) is cut off, the terminal unit (400) can operate while being separated from the live bus.
[0200] Figure 11(c) explains the structure by dividing it into Form 3a and Form 3b.
[0201] In the case of the 3a structure (Form3a), the mother unit (200) and the functional unit (300), and the functional unit (300) and the terminal unit (400) are separated like in the 2a structure (Form2a), but the terminal unit (400) and the mother unit (200) are not separated. That is, the separation of each functional unit (300) is added to the 2a structure (Form2a).
[0202] That is, the above 3a structure is formed by fastening the first plate (611) and the second plate (612) to the frame (510).
[0203] In the case of the 3b structure (Form3b), the separation of the mother unit (200) and the terminal unit (400) is added to the 3a structure (Form3a), and safe operation is implemented.
[0204] Figure 11(d) is described as the 4a structure (Form4a) and the 4b structure (Form4b).
[0205] In the case of the 4a structure (Form4a), the mother unit (200) and the functional unit (300), the terminal unit (400) and the mother unit (200) are separated, similar to the 3b structure (Form3b), and each functional unit (300) is separated, while the functional unit (300) and the terminal unit (400) are not separated.
[0206] In the case of the 4b structure (Form4b), each functional unit (300) is separated from the 4a structure (Form4a), and the functional unit (300) and the terminal unit (400) are separated.

[0210] Fig. 12 is a case of the first structure (Form1), in which an internal bulkhead (600) is not installed in the functional unit (300), the mother unit (200), and the terminal unit (400).
[0211] Figure 13 shows the case of the 2b structure (Form2b), in which the mother unit (200) and the functional unit (300) are separated, but the functional unit (300) and the terminal unit (400) are not separated.
[0212] Accordingly, the above-mentioned 2b structure is a configuration in which a second plate (612) is installed between the mother unit (200) and the functional unit (300).
[0213] Figure 14 is a case of the 3b structure (Form3b), in which the mother unit (200) and the functional unit (300), and the functional unit (300) and the terminal unit (400) are separated, and the separation of the mother unit (200) and the terminal unit (400) is added.
[0214] Accordingly, the above 3b structure is configured by combining a second plate between the mother unit (200) and the functional unit (300) and between the functional unit (300) and the terminal unit (400).

[0218] In addition, the internal bulkheads for each grade are configured to be easily assembled and removed from the frame placed vertically on the exterior, which significantly reduces the time for design changes according to customer requirements and facilitates assembly.
[0219] Additionally, the internal bulkhead can be removed, making it easy to secure assembly space during assembly or product manufacturing, and enabling safe maintenance even during operation.
[0220] In addition, separate manufacturing is not required to satisfy the internal bulkhead structure grade, which reduces the designer's design time and has the effect of simplifying the structure.
