Description

The Body Structure of Connection Panel Formed with Composite Panels

The present invention relates to a body structure of a connection board formed of a composite panel, and in more detail, it provides convenience of mass production and installation along with a reduction in production cost, and a composite that can prevent fire by fundamentally blocking the occurrence of high heat inside the switchboard. It relates to the body structure of the connection board formed by panels.

The connection panel mainly used for electric devices has the function of facilitating opening and closing of a converter or controlling equipment by arranging safety devices, instruments, indicators, and various switches in buildings with electric facilities.
This is a device that monitors and controls the electrical system, and is an assembly consisting of instruments, such as instruments, relays, and switching devices, a support for fixing them, and wires connecting the instruments.
Since the inside of the connection panel is a collection of high-voltage wires and devices, accidents are prevented by checking and controlling it from the outside of the connection panel in order to prepare for failures such as loads.
In this connection panel, various units such as circuit breakers and switchgear are arranged inside the main body to distribute the power supplied from the outside and supply the power to the places where it is needed.
Since a lot of high heat is generated inside the connection panel during input control or output of power, it becomes a disturbing factor or consumes a lot of power.

In addition, an exhaust fan 24 mounted in a vertical line so as to be rotated by a motor 24a is mounted inside the fan housing 22, and foreign matter inflow from the outside to the inside is prevented on the upper part of the exhaust fan 24. A blocking filter 25 is added, and three or more elastic knobs 27 are formed on the outer circumferential surface of the filter 25 at regular intervals to facilitate cleaning and replacement of the filter 25.
In addition, the loop 29 added to the outside of the fan housing 22 is a configuration that forms a smooth curve from the front side to the rear side, as shown in FIG. 10, and is created inside the main body 10 at the front and rear sides. An exhaust duct 28 including an exhaust port 28a for discharging high heat to the outside is further added, and the roof 29 at this time is a smooth curved upper surface or as shown in FIG. 11, from the front side to the rear side. Even if it is made in an inclined shape while facing, there is no significant difference in its effect.
On the other hand, the air inlet means 40 installed below the rear surface 8b constituting the body 10 has a configuration as shown in FIGS. 2 and 4.
That is, a filter box 32, a filter 34 seated in the receiving portion 32a formed in the filter box 32, and a duct 36 having an inlet 36a formed outside the filter 34 are added. It is made of a structure that becomes.
The filter box 32 is a rectangular shape having a receiving portion 32a on the inside, and a plurality of air inlet holes 32b are perforated on the bottom surface, and are coupled to the rear plate 8c using screws 32c on the outside. It is provided with a flange (32d) for doing.
The filter 34 mounted on the receiving portion 32a constituting the filter box 32 has a function of blocking various foreign substances introduced from the outside.
In addition, the wire guide member 50 installed on the bottom plate 8d constituting the body 10 includes a case 42 with an open bottom and side surfaces, and a curtain 44 formed of rubber on one side thereof. As an added configuration, the curtain 44 is to block the introduction of harmful substances into the body 10 by wrapping the outer surface of the electric wire 60 so that no space is created.
Looking at the operating state of the present invention having the configuration as described above is as follows.
That is, when the operating means 20 installed inside the body 10 is operated for a long time, high heat is generated by the flow of current.
At this time, when the internal temperature of the body 10 rises to a certain temperature, the detection sensor 12 detects this and operates the motor 24a constituting the exhaust means 30 mounted on the upper surface 8c to operate the exhaust fan 22 ), while discharging the high heat generated inside the body (10) to the outside, impurities are filtered through the inlet (36a) and filter (34) of the duct (36), and attracts fresh air from outside to the inside. It serves to cool, and the discharged high heat is discharged to the outside through the exhaust ports 28a provided on the front and rear sides of the roof 29 through the filter 25.
In addition, the wire guide member 50 constituting the bottom surface 8d is sealed by holding the outer surface of the electric wire 60 by a curtain 44 formed of rubber, so that external foreign substances are transferred to the inside of the main body 10. The inflow is blocked, and in addition to this, the composite panel 6 constituting the body 10 is formed by adding a compression heat dissipation pad 5c between the inner metal plate 5a and the outer metal plate 5b. By adopting the structure, heat dissipation and winterization effect are improved, so that it is not restricted by temperature change and installation place.
It is not implemented only by the structures described in the embodiments of the present invention described above, but may be implemented through other structures that realize functions corresponding to the configurations of the embodiments of the present invention, and such a configuration is seen from the description of the embodiments described above. It is obvious that it can be easily implemented by an expert in the technical field to which the invention belongs, and that this also belongs to the scope of the invention.

Claims (5)

In a connection board made of a hexahedron, a compression heat dissipation pad (5c) is placed between the inner metal plate (5a) and the outer metal plate (5b) with a thickness of less than 0.7 mm to form a composite panel 6 that does not exceed 7 mm in thickness. Thus, to prevent damage to the outer metal plate 5b, only the inner metal plate 5a and the compression heat dissipation pad 5c were dug in a'V' shape to form a V groove (V), and the outside of the V groove (V). The side metal plate (5b) is bent at a right angle to form a hexahedral body (10), and a sealing blade (8l) is formed on the front of the body (10) to contaminate the door (9) and the upper surface (8c) with a viewing window (9a). It constitutes a filter 25 having an elastic knob 27 that can be disassembled when cleaning and replacing the material, and an exhaust duct 28 having an inclined exhaust port 28a at the front and rear surfaces. A loop (29) that can be disassembled and coupled is configured to be disassembled on the upper portion of the body (10), and a filter (34) is formed in the receiving portion (32a) under the inner rear surface (8b) of the body (10) And a filter box 32 having a plurality of air inlet paths 32b on the bottom surface 8d and a duct 36 integrally fixed to the outside of the rear plate by forming an inlet.
