Technology Field

[0001] The present invention relates to a switchboard, and more specifically, to a switchboard capable of rapidly extinguishing a fire when a fire occurs in the switchboard. Background Technology

[0003] Generally, a distribution panel is a device that houses and wires various switches, relays, etc., for power distribution.

[0004] It is considerably difficult to detect and extinguish fires in such distribution panels when they occur due to external forces such as earthquakes or internal problems such as insulation breakdown and arc generation.

Brief explanation of the drawing

[0032] FIG. 1 is a conceptual diagram briefly illustrating a switchboard according to the present invention. FIG. 2 is a cross-sectional view illustrating the operational relationship of the main parts of a switchboard according to the present invention. Specific details for implementing the invention

[0033] A preferred embodiment of the switchboard according to the present invention will be described in detail with reference to the attached drawings.

[0035] FIG. 1 is a conceptual diagram briefly illustrating a switchboard according to the present invention, and FIG. 2 is a cross-sectional view illustrating the operational relationship of the main parts of the switchboard according to the present invention.

[0037] As shown in FIGS. 1 and 2, the distribution board according to the present invention comprises a distribution board body (1) in which an electrical device or a communication device is largely accommodated in an internal space, and a fire prevention means (2) installed inside the distribution board body (1) and operated by a change in internal pressure in the event of a fire.

[0039] Here, the fire prevention means (2) supplies an inert gas when operating, preferably carbon dioxide.

[0041] Specifically, as illustrated in FIG. 2, the fire prevention means (2) comprises a receptacle (4) having an internal receiving portion (3) formed vertically inside, a movable body (6) installed within the internal receiving portion (3) and sliding along the internal receiving portion (3) and having an L-shaped connecting hole (5) formed connecting the upper surface and the rear surface, and an elastic body (7) installed on the lower side of the movable body (6) in the internal receiving portion (3) and elastically pressurizing and supporting the movable body (6).

[0043] Here, the receiver (4) is preferably formed as a rectangular prism and is provided with a fixing hole (8) formed horizontally on the upper and lower sides respectively, to which a fixing means such as a bolt is installed for fixing to the wall of the distribution board body (1), a fastening and penetration hole (9) installed through the rear side of the inner receiving part (3) to connect the inner receiving part (3) to the outside and having a female screw part formed on the inner circumference, and a guide hole (10) connecting the upper part of the inner receiving part (3) to the outside.

[0045] In addition, the internal receiving part (3) and the movable body (6) are formed in a rectangular shape and are extended in the vertical direction. The movable body (6) is positioned so that it is supported by the upper surface of the internal receiving part (3), thereby restricting its movement in the vertical direction, and normally, it is supported by an elastic body (7) so that its upper surface is positioned to be in contact with the upper surface of the internal receiving part (3).

[0047] The elastic body (7) may be equipped with various types of elastic means, but a compression coil spring is preferred.

[0049] In addition, in the present invention, when the movable body (6) comes into contact with the upper surface of the internal receiving part (3), the connecting hole (5) and the fastening and through hole (9) are blocked from each other, and when the movable body (6) is pressurized by the fluid introduced through the guide hole (10) and elastically deforms the elastic body (7) to move downward, the connecting hole (5) and the fastening and through hole (9) are configured to be connected to each other.

[0051] Additionally, the fire prevention means (2) is provided with a storage container (11) for accommodating an inert gas such as carbon dioxide, and the storage container (11) is a container in which a male screw part that is screw-coupled with a fastening and through hole (9) is provided on the outlet side and pressurized carbon dioxide is filled inside, and a small gas cylinder, etc. may be used.

[0053] To explain the operation process of the switchboard according to the present invention configured as described above, as described above, the movable body (6) maintains a state of being moved upward due to the elasticity of the elastic body (7) during normal operation, and at this time, the connecting hole (5) and the fastening and through hole (9) maintain a state of being unconnected {refer to FIG. 2 (a)}.

[0055] When the internal pressure increases due to a fire inside the distribution board, this pressure acts on the movable body (6) through the guide hole (10) of the fire prevention means (2), causing the movable body (6) to overcome the elastic force of the elastic body (7) and move downwards. At this time, the connection hole (5) and the fastening and penetration hole (9) remain connected. As a result, carbon dioxide inside the storage container (11) is supplied into the main body of the distribution board (1) through the fastening and penetration hole (9), the connection hole (5), and the guide hole (10), thereby preventing the propagation or spread of the fire. Thus, the discharge of carbon dioxide increases the internal pressure of the distribution board, thereby keeping the movable body (6) in a continuously open state (see Fig. 2 (b)).

[0057] Through the configuration described above, the distribution panel of the present invention can quickly suppress or extinguish abnormalities such as fires, and has advantages such as being easy to manufacture due to its simple structure, having few breakdowns, and easy maintenance.
