Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grounding copper bars, and particularly relates to a grounding copper bar with a structure for accelerating conductivity. Background Technique
[0002] A grounding copper bar is a device used in an electrical system to electrically connect electrical equipment to the ground. It is usually made of highly conductive copper and is an important part of the electrical system for achieving the safe grounding of the system. The grounding copper bar can effectively introduce the fault current on the electrical equipment into the ground, prevent the occurrence of electric shock accidents, and protect the safety of personnel.
[0003] In a system with high requirements for conductivity, due to the poor conductivity and large resistance of ordinary copper bars, it may affect the voltage stability and power supply quality at the load end. The higher resistance will cause the power system to require more electrical energy to compensate for the losses, resulting in greater electrical energy consumption and increased operating costs, which is not conducive to the goal of energy conservation and emission reduction.
[0004] Therefore, we hope to design a grounding copper bar with a structure for accelerating conductivity to solve this problem. Content of the Utility Model
[0005] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a grounding copper bar with a structure for accelerating conductivity, and solve the problems put forward in the above background technique.
[0006] The utility model is realized through the following technical solutions: A grounding copper bar with a structure for accelerating conductivity includes a protective shell and a protective cover. A buckle fixing belt is arranged on the outer side of the protective shell, and the protective shell and the protective cover are fixedly connected through the buckle fixing belt. A composite copper bar is arranged inside the protective shell, and a fixing component is arranged on the composite copper bar.
[0007] The composite copper bar includes a first copper bar. A second copper bar is fixedly connected to the upper side of the first copper bar through a fixing component. A graphene film is arranged between the first copper bar and the second copper bar. By setting the composite copper bar, the conductivity of the device is improved.
[0008] As a preferred implementation manner, the upper surface of the first copper bar and the lower surface of the second copper bar are both reticular structures. The first copper bar and the second copper bar with the surface reticular structures are used to increase the contact area with the graphene film. By increasing the surface area of the first copper bar and the second copper bar, the contact area with the graphene film is increased, the contact resistance is reduced, and the conductivity is enhanced.
[0009] As a preferred embodiment, the fixing component includes a bolt. A clamping block is fixedly connected to the lower side of the upper end of the bolt. A collar is movably connected to the outer side of the bolt. The collar is fixedly connected to the second copper bar. The first copper bar and the graphene film are movably sleeved on the outer side of the bolt. A limiting component is arranged inside the collar. By setting the fixing component, the connection between the first copper bar and the second copper bar is made more stable, reducing the contact resistance while maintaining good contact.
[0010] As a preferred embodiment, through holes are formed on both sides of the first copper bar and the graphene film. The through holes are used for sleeving the bolt. Threaded holes are formed on both sides of the second copper bar. The first copper bar and the second copper bar are connected by the bolt.
[0011] As a preferred embodiment, the limiting component includes a spring. One end of the spring is fixedly connected to the collar. The other end of the spring is fixedly connected to a limiting block. The limiting block is slidably sleeved inside the collar. By setting the limiting component, it is prevented that the bolt rotates to make the connection between the first copper bar and the second copper bar unstable, further causing the deterioration of the electrical conductivity.
[0012] As a preferred embodiment, one side of the upper end of the limiting block is arc-shaped. The arc-shaped limiting block is used to reduce the resistance between the clamping block and the limiting block.
[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: By adding graphene film materials between the copper bars, graphene has extremely high electrical conductivity, which can significantly improve the overall electrical conductivity, reduce the electrical energy compensation required by the power system, maintain normal operation, reduce the overall energy consumption, and is beneficial to the goal of energy conservation and emission reduction. In addition, by setting protection components, it can play a protective role for the copper bars when they are not in use, reducing the oxidation rate of the copper bars and preventing dust, dirt or other pollutants from adhering to the surface of the copper bars, which may affect the electrical conductivity and long-term use of the copper bars.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a grounding copper bar with a structure for accelerating conductivity, including a protective shell 1 and a protective cover 3. A buckle fixing band 2 is arranged on the outer side of the protective shell 1. The protective shell 1 and the protective cover 3 are fixedly connected through the buckle fixing band 2. A composite copper bar 4 is arranged inside the protective shell 1, and a fixing component 5 is arranged on the composite copper bar 4;
[0024] The composite copper bar 4 includes a first copper bar 41. A second copper bar 42 is fixedly connected to the upper side of the first copper bar 41 through a fixing component 5. A graphene film 43 is arranged between the first copper bar 41 and the second copper bar 42. By arranging the composite copper bar 4, the conductivity of the device is improved.
[0025] The upper surface of the first copper busbar 41 and the lower surface of the second copper busbar 42 are both reticular structures. The first copper busbar 41 and the second copper busbar 42 with the surface reticular structure are used to increase the contact area with the graphene film 43. By increasing the surface area of the first copper busbar 41 and the second copper busbar 42, the contact area with the graphene film 43 is increased, the contact resistance is reduced, and the electrical conductivity is enhanced.
[0026] The fixing component 5 includes a bolt 51. A clamping block 52 is fixedly connected to the lower side of the upper end of the bolt 51. A collar 53 is movably connected to the outer side of the bolt 51. The collar 53 is fixedly connected to the second copper busbar 42. The first copper busbar 41 and the graphene film 43 are movably sleeved on the outer side of the bolt 51. A limiting component 54 is arranged inside the collar 53. By arranging the fixing component 5, the connection between the first copper busbar 41 and the second copper busbar 42 is made more stable, and the contact resistance is reduced while maintaining good contact.
[0027] Through holes are opened on both sides of the first copper busbar 41 and the graphene film 43 for sleeving the bolt 51. Threaded holes are opened on both sides of the second copper busbar 42. The first copper busbar 41 and the second copper busbar 42 are connected by the bolt 51.
[0028] The limiting component includes a spring 541. One end of the spring 541 is fixedly connected to the collar 53, and the other end of the spring 541 is fixedly connected to a limiting block 542. The limiting block 542 is slidably sleeved inside the collar 53. By arranging the limiting component 54, it is prevented that the bolt 51 rotates to cause unstable connection between the first copper busbar 41 and the second copper busbar 42, which further leads to poor electrical conductivity.
[0029] One side of the upper end of the limiting block 542 is arc-shaped. The arc-shaped limiting block 542 is used to reduce the resistance between the clamping block 52 and the limiting block 542.
[0030] Please refer to Figures 2 - 5, as the first embodiment of the present utility model: The graphene film 43 is clamped between the first copper bar 41 and the second copper bar 42, then the bolt 51 is passed through the through holes of the second copper bar 42 and the graphene film 43, and finally the bolt 51 is rotated so that the bolt 51 is threadedly connected to the threaded hole of the first copper bar 41. Since the graphene film 43 has extremely high electrical conductivity, adding the graphene film 43 in the middle of the composite copper bar 4 can significantly improve the electrical conductivity of the device to reduce resistance loss. At the same time, during the process of rotating the bolt 51, the block 52 on the lower side of the upper end of the bolt 51 rotates simultaneously and presses the limiting block 542. Since one side of the limiting block 542 is arc-shaped, the resistance between the block 52 and the limiting block 542 is reduced. When the limiting block 542 is subjected to force, it moves into the inside of the collar 53 and presses the spring 541 to deform it. When the block 52 rotates past the limiting block 542, the limiting block 542 slides out of the surface of the collar 53 under the elastic force of the spring 541 and restricts the position of the block 52 to prevent it from reversing.
[0031] Please refer to Figures 1 - 3 , as the second embodiment of the present utility model: Based on the description in the above embodiment, further, when the composite copper bar 4 is not in use, the composite copper bar 4 can be placed inside the protective shell 1, then the protective cover 3 is covered, and finally the snap fixing belt 2 is wound around the outside of the protective shell 1 and the protective cover 3 to fix it on the upper side of the protective shell 1. In this way, it can protect the composite copper bar 4 inside, reduce the oxidation rate of the composite copper bar 4, and at the same time prevent dust, dirt or other pollutants from adhering to the surface of the composite copper bar 4, resulting in the influence on the electrical conductivity and service life of the composite copper bar 4.
[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
