Description

Busbar structure for uniformly distributing current

Technical Field

The utility model relates to a female structure field of arranging, in particular to female structure of arranging of equipartition electric current.

Background

The busbar is a main power supply line of the power distribution and supply device, when alternating current or alternating electromagnetic field exists in the conductor, the current distribution in the conductor is uneven, the current is concentrated on the skin part of the conductor, namely the current is concentrated on the thin layer on the outer surface of the conductor, the closer to the surface of the conductor, the higher the current density is, and the smaller the current is actually in the conductor. As a result, the resistance of the conductor increases, and its power loss also increases.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a female structure of arranging of equipartition electric current that does benefit to electric current direction and distributes.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a female structure of arranging of equipartition electric current, includes the multilayer conductor layer of range upon range of setting, multilayer conductor layer both ends tip reciprocal anchorage, be provided with the internal insulation layer between every two-layer conductor layer middle section.

Further, the method comprises the following steps: and an outer insulating layer is wrapped outside the middle section of the busbar structure formed by the multilayer conductor layer and the inner insulating layer.

Further, the method comprises the following steps: the conductor layer is copper, aluminum or nickel.

Further, the method comprises the following steps: the inner insulating layer and the outer insulating layer are made of PET, PI insulating films, epoxy resin, FR4, GPO or plastics.

Further, the method comprises the following steps: the end parts of the two ends of the multilayer conductor layer are fixed in a tin soldering mode, a silver soldering mode, a high-molecular diffusion welding mode, a pressing mode or a locking mode.

The utility model has the advantages that: the busbar structure shown in the product scheme utilizes the skin effect characteristic of the conductor to uniformly distribute the current on each conductor layer, and is more favorable for guiding and distributing the current than the conventional busbar structure. Meanwhile, the addition of the insulating layer is more beneficial to the heat dissipation of the product.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

The bus bar structure comprises multiple conductor layers which are arranged in a stacked mode, end portions of two ends of each multiple conductor layer are fixed to each other, an inner insulating layer is arranged between middle sections of every two conductor layers, each conductor layer is made of copper, aluminum or nickel, the inner insulating layer and the outer insulating layer are made of PET, PI insulating films, epoxy resin, FR4, GPO or plastics and the like, end portions of two ends of each multiple conductor layer are fixed in a tin soldering mode, a silver soldering mode, a high-molecular diffusion welding mode, a pressing mode or a locking mode and the like, when alternating current or an alternating electromagnetic field exists in a conductor, current distribution inside the conductor is uneven, the current is concentrated on the skin portion of the conductor, namely the current is concentrated on a thin layer on the outer surface of the conductor, the current density is larger the closer to the surface of the conductor, and the current inside the conductor. As a result, the resistance of the conductor increases, and its power loss also increases. This phenomenon is called skin effect. The bus bar structure shown in the product scheme makes use of the skin effect characteristic of the conductor to uniformly distribute the current on each conductor layer, and is more favorable for guiding and distributing the current than the conventional bus bar structure. Meanwhile, the addition of the insulating layer is more beneficial to the heat dissipation of the product.

On the basis, as shown in fig. 2 and 3, the outer insulating layer wraps the middle section of the busbar structure formed by the multiple conductor layers and the inner insulating layer, the functions of heat dissipation, edge bonding and the like of the product can be increased due to the arrangement of the outer insulating layer, and the outer insulating layer can be arranged according to actual requirements.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
