[0027] Generally, a distribution panel is designed to mount various circuit breakers and switches inside an enclosure to draw power from the outside and distribute it, while simultaneously enabling the selective supply of power.

[0028] Such a distribution panel includes an enclosure to prevent electric shock and various electrical safety accidents in order to prevent the power lines from being exposed to the outside. In particular, the distribution panel includes a circuit breaker to achieve electrical safety by cutting off the current supply in the event of an overload during the process of distributing the main power supplied from the outside to each electrical load.

[0029] FIG. 1 is a schematic diagram of a switchboard capable of preventing electric shock accidents according to one embodiment of the present disclosure.

[0030] Referring to FIG. 1, the distribution board may include a main circuit breaker (110) connected to a main input terminal into which external power is supplied, an auxiliary circuit breaker (120) connected to the main circuit breaker (110), a plurality of branch circuit breakers (130), and a busbar unit (140) that electrically connects the circuit breakers (110, 120, 130).

[0031] Specifically, a switchboard capable of preventing electric shock accidents according to one embodiment of the present invention is characterized by being able to minimize the risk of electric shock accidents and to prevent the bolts securing the busbar from loosening.

[0032] The above-described distribution panel is formed in the shape of an enclosure having an internal storage space, and an opening is formed on one side to communicate with the storage space. Additionally, a door may be installed in the opening to selectively seal the storage space.

[0033] In addition, power lines are installed on one side of the distribution panel formed in the shape of an enclosure so that they can be inserted and removed.

[0034] The main circuit breaker (110) has an input power line (112) connected to the input terminal (111) and the secondary terminal (113) is connected to the primary terminal (115) of the auxiliary circuit breaker (120) or each branch circuit breaker (130) through the power connection line (114), and a power output line (117) is connected to the secondary terminal (116) of the auxiliary circuit breaker (120) or branch circuit breaker (130) so that the commercial power applied to the input power line (112) is supplied to the place of electricity use through the power output line (117).

[0035] The auxiliary circuit breaker (120) is electrically connected to the main circuit breaker (110) and can inform the current status of the circuit breakers (110, 120, 130) and help to safely interlock the equipment.

[0036] The branch circuit breaker (130) performs the on / off function for each part of the electricity distributed from the main circuit breaker (20), and can be electrically connected to the main circuit breaker (110) in the same way as the auxiliary circuit breaker (120).

[0037] Meanwhile, the busbar unit (140) connects the auxiliary circuit breaker (120) or branch circuit breaker (130) to the main circuit breaker (110), and is installed in correspondence with the number of auxiliary circuit breakers (120) and branch circuit breakers (130). That is, multiple units can be installed depending on the load desired by the user.

[0038] The above busbar unit (140) may include a plate (141) whose length is variable and which is coupled or separated in multiple numbers according to the number of auxiliary circuit breakers (120) and branch circuit breakers (130); a plurality of main busbars (142) which are coupled along the length direction of the plate (141) and have one end connected to the main circuit breaker (110); branch busbars (143) which are positioned orthogonally to the main busbars (142), with a portion connected to the main busbars (142) via bolts and both ends connected to the auxiliary circuit breaker (120) or branch circuit breaker (130), respectively; a bracket (144) which is installed upright at each of the four corners of the outermost edge of the plate (141) to which multiple numbers are coupled, and has a coupling hole formed at the top; and a plate-shaped transparent cover (145) which is coupled or separated from the coupling hole of the bracket (144).

[0039] A plurality of plates (141) are provided, formed in a plate shape having a predetermined area, and are formed such that they can be joined or separated from one other. A joining projection (141a) for mutual joining is formed protruding on one side, and a joining groove (141b) is formed on the other side so that the joining projection (141a) can be inserted and fixed.

[0040] In addition, a plurality of fitting holes (141c) are formed on the upper side of the plate (141) so that a busbar (142) electrically connected to the main circuit breaker (110) can be fitted.

[0041] The busbar (142) is formed in the shape of a rail and is connected to each of the multiple fitting holes (141c). It is made of metal and is formed to have a predetermined length, serving to allow commercial electricity flowing through the main circuit breaker (110) to flow.

[0042] At this time, the busbar (142) can be formed in an "L" shape or a "└┘" shape to improve the bonding strength with the plate (141).

[0043] Here, in one embodiment of the present invention, the shape of the busbar (142) is described as an "L" shape or a "└┘" shape, but this is for convenience of explanation and is not limited to any shape as long as it can improve the bonding strength with the plate (141).

[0045] That is, the branch busbar (143) is positioned orthogonally to the main busbar (142), and a portion of it is bolted to the main busbar (142). In addition, both ends of the branch busbar (143) are connected to an auxiliary circuit breaker (120) or a branch circuit breaker (130).

[0046] Here, in a switchboard capable of preventing electric shock accidents according to one embodiment of the present invention, a rib (141d) is formed to protrude from the upper side of the plate (141) to prevent short circuits between a plurality of branch busbars (143) installed orthogonally to the plurality of main busbars (142).

[0047] That is, except for the part connecting the main busbar (142) and the branch busbar (143), the main busbar (142) and the branch busbar (143) are not in contact by the rib (141d), thereby preventing a short circuit between the main busbar (142) and the branch busbar (143).

[0048] Meanwhile, the bracket (144) is installed upright at each of the outermost four corners of the plate (141) which is joined in a plate shape, and is configured so that the transparent cover (145) can be joined or separated.

[0049] Specifically, the bracket (144) is installed at the four corners of the mutually coupled plate (141) and consists of a column part (144a) which is installed upright so that the transparent cover (145) to be supported can be spaced apart from the bus bar (142, 143) by a predetermined height or more, a support part (144b) which is formed at the top of the column part (144a) and can support the transparent cover (145), a pressure part (144c) which has elastic restoring force and presses the upper side of the transparent cover (145) seated on the support part (144b) to prevent the transparent cover (145) from being separated from the column part (144a), and a button part (144d) which is formed integrally with the pressure part (144c) and allows the pressure part (144c) to be spaced apart from the transparent cover (145) by pressing with a user's finger.

[0050] The transparent cover (145) is seated on the bracket (144) to cover the upper side of the bus bars (142, 143) and can be formed in the shape of a plate made of a transparent material.

[0051] At this time, the transparent cover (145) is designed to prevent dust generated during long-term operation, shocks transmitted to the busbar, and arcs that may occur due to electrical or mechanical defects in the accessories.

[0052] Meanwhile, in a distribution board capable of preventing electric shock accidents according to one embodiment of the present invention, a cap (146) made of an insulating material may be attached to the bolt connecting the main busbar (142) and the branch busbar (143).

[0053] The above cap (146) is designed so that the user will not be electrocuted even if they accidentally touch the bolt.

[0054] That is, the switchboard capable of preventing electric shock accidents according to one embodiment of the present invention, configured as described above, can prevent electric shock accidents through the cap (146) and minimize the loosening of bolts even under vibration.

[0055] In addition, the embodiment of the present invention allows the transparent cover (145) to be easily and conveniently attached or detached through the bracket (144), and the transparent cover (145) covers the busbars (142, 143), thereby blocking dust or foreign matter from entering the busbars (142, 143) and preventing electric shock or fire accidents.

[0056] Although embodiments of the present disclosure have been described above, those skilled in the art may modify or change the present disclosure in various ways by adding, changing, deleting, or adding components without departing from the technical spirit of the present disclosure as described in the claims, and such modifications or changes shall also be deemed to be included within the scope of the rights of the present disclosure.
