Heat-dissipation type copper bar

Abstract

The invention discloses a heat-dissipation type copper bar, and belongs to the technical field of electrical equipment. The copper bar comprises a copper bar body 1, and the cross section of the copper bar body 1 has a U-shaped structure. The surface of the copper bar body 1 is provided with a plurality of heat-dissipation through holes 2, and is coated with an oxidation resistant layer 3. The surface of the copper bar body 1 is coated with the oxidation resistant layer 3. A side surface of the copper bar body 1 is provided with at least two silvered material projections 4. The bottom surface of the copper bar body 1 is provided with a through hole 5. Two side surfaces of the copper bar body 1 are two different concave-convex surfaces 6 and 7. The copper bar employs a new structure, is high in overall strength, is good in stability, is additionally provided with the heat-dissipation holes, can improve the heat-dissipation efficiency in a use process, is convenient to assemble, can be used in many occasions, and shortens the installation time.

Description

technical field [0001] The invention relates to the technical field of large-scale transformer accessories, in particular to a heat-dissipating copper bar that can heat up quickly, save electric energy and is not easily oxidized, in particular a heat-dissipating copper bar. Background technique [0002] Copper bars are conductor materials for making motor electrical winding coils, high and low voltage electrical switch contacts, and power supply and distribution equipment installation. The transformer is connected to the inlet and outlet ends of the low-voltage coil with a copper bar. The low-voltage copper bar in the prior art is made of a single copper plate with a large thickness, and its cross-section is rectangular. This rectangular copper bar has poor heat dissipation during use. It is easy to cause failure during long-term operation, and it is easy to be oxidized during work and use, thereby increasing the resistance value, which in turn causes a large temperature ris...

The transformer is connected to the inlet and outlet ends of the low-voltage coil with a copper bar. The low-voltage copper bar in the prior art is made of a single copper plate with a large thickness, and its cross-section is rectangular. This rectangular copper bar has poor heat dissipation during use. It is easy to cause failure during long-term operation, and it is easy to be oxidized during work and use, thereby increasing the resistance value, which in turn causes a large temperature rise of the copper bar, which wastes electric energy and is not conducive to safe power supply
