Bus bar {Busbar}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bus bar, and more particularly, to a bus bar in which a conductive tube is formed of a hollow tube body, So as to maximize the energizing current through the bus bar and to have a bending strength with respect to the magnetic force generated between the peripheral bus bars.

Generally, a bus bar is installed in an electric distribution board or a distribution board to distribute and supply high-voltage and high-current currents.

In order to maximize the current flow due to the skin effect, the bus bar is formed with a tubular body or a large diameter in order to maximize the surface area.

However, the conventional bus bar is limited in its installation place and its size is limited. In the course of its use, heat is generated in the process of energization, and a bending load due to a magnetic force generated between the bus bars And the strength is so weak that it is easily broken.

Accordingly, as described above, the conventional bus bar is limited in its place and its size is limited. In the course of its use, heat is generated in the energization process, and a bending load due to a magnetic force generated between the bus bars But the problem that the heat dissipation is not smooth and the strength is weak and is easily broken can be solved.

That is, in the bus bar of the present invention, in the bus bar, the conductive tube is formed of a hollow tube and the inner surface and the outer surface are formed with a skin area enlarged rib for increasing the durability against the magnetic force of the peripheral bus bar and maximizing the skin current will be.

Therefore, by forming ribs for increasing the skin area on the inner and outer surfaces of the bus bar formed of the hollow tube, the energization current through the bus bar is maximized and the bending strength against the magnetic force generated between the peripheral bus bars is improved, To maintain sufficient mechanical strength in current transmission and distribution.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is intended to maximize the energizing current through the bus bar and to improve the bending strength with respect to the magnetic force generated between the peripheral bus bars and to maintain a sufficient mechanical strength in the large current transfer and distribution.

That is, the present invention provides a bus bar which is installed in an electric distribution board or a distribution board and distributes and supplies a current of high voltage and large current, and is characterized in that the conductive tube 10 is formed of a hollow tube and the durability against the magnetic forces of the peripheral bus bars on the inner and outer surfaces is improved And a skin area enlarging rib 1 for maximizing the skin current is formed.

The depth of the skin surface area enlarging rib 1 on the inner surface of the conductive tube 10 is longer than the depth of the skin surface area enlarging rib 1 formed on the outer surface of the conductive tube 10, The skin area can be formed to have the same area.

It is also possible to form the skin area increasing hole 3 for increasing the skin area between the skin area enlarging ribs 1 on the inner and outer surfaces of the conductive tube 10

The skin area enlarging rib 1 may be formed by selectively forming a rectangular rib, a triangular rib or a circular rib.

On the other hand, the skin area enlarging rib 1 can be formed as a "T" rib so as to form an "I" shaped section having a high section modulus so as to increase the bending strength by maximizing the section modulus.

The skin-surface-enlarged ribs 1 on the inner surface and the outer surface can be staggered so as to improve the bending strength.

Further, in the practice of the present invention, ventilation holes 2 can be formed at regular intervals so that air is blown into the hollow portion 11 at regular intervals on the conductive tube 10.

The vent hole (2) is formed so as to communicate with the skin surface area increasing hole (3).

Hereinafter, the use process of the present invention will be described.

As described above, in the bus bar, the conductive tube 10 is formed of a hollow tube, and the skin area enlarging ribs 1 are formed on the inner and outer surfaces so that the durability against the magnetic force of the peripheral bus bars is improved and the skin current is maximized When the present invention is applied, the current passing through the bus bar is maximized, the bending strength with respect to the magnetic force generated between the peripheral bus bars is improved, and sufficient mechanical strength is maintained in the large current transfer and distribution.

In the embodiment of the present invention, the depth of the skin surface area enlarging rib 1 on the inner surface of the conductive tube 10 is longer than the depth of the skin surface area enlarging rib 1 formed on the outer surface of the conductive tube body 10 The surface area of the inner surface of the conductive tube 10 is equal to the surface area of the outer surface so that the internal resistance is equal between the inner surface and the outer surface of the conductive tube 10 and the conductive current is uniformly dispersedly transferred.

In addition, in the practice of the present invention, when the skin surface area increasing hole 3 for increasing the skin surface area is formed between the skin surface area enlarging ribs 1 on the inner and outer surfaces of the conductive tube 10, 10 is energized by the skin current through the skin area increasing hole 3 to maximize the amount of electric current flow and the skin area increasing hole 3 has a high sectional modulus of wall material of the conductive tube body 10, Is formed into an excellent hollow wall, and the mechanical strength is improved along with the increase of the energizing current.

In addition, in the practice of the present invention, when the skin area enlarging rib 1 is formed as a "T" rib, the "T" rib is formed as an "I" rib having a maximum section modulus, And the heat generated by the energization process due to the heat generation by the notch along with the surface heat generation is smoothly released to the air.

In addition, if the ribs 1 for increasing the skin area of the inner and outer surfaces are staggered so as to improve the bending strength, the thickness of the wall of the conductive tube 10 is maximized and the mechanical strength is improved.

In the practice of the present invention, ventilation holes 2 are formed in the conductive pipe body 10 at regular intervals so as to allow air to be blown into the hollow portions 11, When the conductive tube 10 and the skin area increasing hole 3 are formed to communicate with the enlarging hole 3, the air is smoothly flowed through the conductive tube body 10 and the skin area increasing hole 3, so that the heat generated during the current conduction is smoothly discharged into the air .
