Description

Weektube busbar

[0001] The present invention relates to a wick tube busbar, and more specifically, to a busbar having a support wick that has a high current repulsion support force inside a current-carrying tube, thereby improving the high current repulsion support force of the tube busbar.

[0002] Generally, busbars are used to distribute large currents in distribution panels.

[0003]

[0004] Most busbars like the above are formed in a plate shape to minimize electrical resistance and maximize conduction current.

[0005]

[0006] Meanwhile, when the above busbar is formed into a flat plate, there is a problem of deformation or cutting damage due to the high current repulsion force, so a tube busbar with a high cross-sectional modulus and high mechanical strength is used to improve its mechanical strength.

[0007]

[0008] However, the tube busbar as described above also had a problem in that its central portion was damaged by bending because its mechanical strength against high current repulsion was insufficient.

[0009]

[0010] Accordingly, the present invention aims to solve the problem that the tube busbar as described above does not have sufficient mechanical strength against a large current repulsion force, resulting in bending damage in the central portion.

[0011] That is, the present invention is characterized by comprising a bus bar, a current-carrying tube formed into a tube body to conduct electricity and have support rigidity, a support wick provided inside the current-carrying tube to have a high current repulsion support force, a wick clamping portion provided at both ends of the current-carrying tube so as to be connected to the support wick, an insulating space formed between the outer side of the support wick and the inner side of the current-carrying tube, and a tube heat-conducting coating portion provided on the outer side of the current-carrying tube for insulation.

[0012] Accordingly, the present invention has the effect of improving the high current repulsion support capacity of a tube bus bar by providing a support wick having a high current repulsion support capacity inside a current-carrying tube.

[0020] The present invention is intended to improve the high current resistance of a tube bus bar. Terms or words used in this specification and claims should not be interpreted as limited to their usual or dictionary meanings, and should be interpreted as meanings and concepts that conform to the technical idea of ​​the present invention based on the principle that the inventor can appropriately define the concept of a term to explain his or her own invention in the best possible way.

[0021] Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0022]

[0023] That is, the present invention is a bus bar composed of a current-carrying tube (100), a support wick (200), a wick clamping portion (300), an insulating space portion (400), and a tube heat-conducting covering portion (500).

[0024]

[0025] Here, the above-mentioned electric tube (100) is formed into a tube body so that electricity can be passed through it and it has supporting rigidity.

[0026] This can be done by forming tube ventilation holes (110) at equal intervals in the above-mentioned conductive tube (100) with a gap and diameter that does not reduce the mechanical strength of the conductive tube by more than 10%.

[0027] The above tube ventilation holes (110) can be formed at equal intervals in a spiral shape so that the air inside the electric current tube can circulate.

[0028]

[0029] And, the above support wick (200) is provided inside the electric tube to have a high current repulsion support force.

[0030] The above support wick (200) can be formed of a material having a lower resistance value than the current-carrying tube so as to maximize the current-carrying capacity of the bus bar.

[0031] It is preferable that the above support wick (200) be made of a superconducting material.

[0032] The above support wick (200) can be made of any one of a plate-shaped wire, a circular wire, and a tubular wire.

[0033] It is possible to form a wick insulation layer (210) on the outer surface of the above-mentioned support wick (200) to prevent contact short circuit when the current-carrying tube is bent due to external force.

[0034]

[0035] In addition, the above-mentioned wick clamping part (300) is provided so that it can be connected to the support wick at both ends of the electric tube (100).

[0036] The above-mentioned weak clamping part (300) can also be provided in the central part of the current-carrying tube (100).

[0037] The above-mentioned weak clamping part (300) can be implemented by forming a mounting hole (310) for mounting by electrical connection in the distribution board.

[0038]

[0039] In addition, the insulating space (400) is formed between the outer side of the support wick (200) and the inner side of the conductive tube (100).

[0040] In addition, the above tube heat-conducting covering (500) is provided on the outside of the above current-conducting tube (100) for insulation.

[0041]

[0042] Hereinafter, the operational effects according to the application of the present invention will be described as follows.

[0043] As described above, when the present invention is applied and implemented, which comprises a current-carrying tube (100) formed into a tube body to conduct electricity and have support rigidity in a bus bar, a support wick (200) provided inside the current-carrying tube to have a high current repulsion support force, a wick clamping portion (300) provided at both ends of the current-carrying tube so as to be connected to the support wick, an insulating space portion (400) formed between the outer side of the support wick and the inner side of the current-carrying tube, and a tube heat-conducting coating portion (500) provided on the outer side of the current-carrying tube for insulation, the high current repulsion support force of the tube bus bar can be improved.
