Description

Technical Field

[0001] The utility model relates to the field of conductive rod structures, in particular to a copper conductive rod for an environmental protection cabinet. Background Art

[0002] Copper conductive rods for environmental switchgear are used in power systems, particularly in medium and low voltage distribution. They are primarily used to protect electrical equipment, improve energy efficiency, and reduce environmental pollution. A key component of environmental switchgear, copper conductive rods function as conductors and current transmitters. Environmental switchgear is a new type of power distribution equipment, often replacing traditional sulfur hexafluoride (SF6) gas-insulated switchgear, reducing its negative environmental impact. Copper conductive rods, a conductive component in environmental switchgear, are made of high-purity copper and are used to transmit current between electrical equipment. Copper is widely used in power systems due to its excellent electrical conductivity (second only to silver). Copper conductive rods efficiently transmit current and reduce energy loss. Copper's strong oxidation and corrosion resistance enable long-term stable operation in harsh environments. Copper conductive rods also possess a certain mechanical strength to withstand the stresses of installation and operation.

[0003] To improve conductivity, a silver coating is applied to the corresponding locations of the copper conductive rods. This coating is typically achieved through chemical plating or electroplating. Due to the unique structure of the copper conductive rods used in environmental protection cabinets, processing is difficult and the coating process is also complex. Utility Model Content

[0031] Reference Figures 1 to 8 In one embodiment of the present invention, a copper conductive rod for an environmental protection cabinet includes:

[0032] The fixed ring end 100 includes an inner cylindrical portion 110, a columnar portion 120 and an outer cylindrical portion 130 connected to each other in the length direction. The inner cylindrical portion 110 and the outer cylindrical portion 130 are both cylindrical, and the columnar portion 120 is columnar.

[0033] The cylindrical section 200 is cylindrical in shape, and has the same inner diameter and diameter as the inner cylindrical portion 110. The inner and outer walls of the end of the cylindrical section 200 away from the fixing ring end 100 are provided with a first silver coating 300, and all surfaces of the outer cylindrical portion 130 are provided with a second silver coating 400.

[0034] The cylindrical section 200 and the inner cylindrical portion 110 are friction welded on the end surfaces.

[0035] In the prior art, in order to improve the conductive performance, a silver plating layer is provided at the corresponding position of the copper conductive rod, and the plating is generally achieved by chemical plating or electroplating. Due to the special structure of the copper conductive rod used in the environmental protection cabinet, the processing is more difficult and the plating process is also more complicated.

[0036] The copper conductive rod for an environmental protection cabinet provided by the present invention includes a fixed ring end 100 and a cylindrical section 200. The fixed ring end 100 includes an inner cylindrical portion 110, a columnar portion 120 and an outer cylindrical portion 130 that are connected to each other in the length direction. The inner cylindrical portion 110 and the outer cylindrical portion 130 are both cylindrical, and the columnar portion 120 is columnar. The lengths of the inner cylindrical portion 110, the columnar portion 120 and the outer cylindrical portion 130 are selected according to actual usage. The cylindrical section 200 is cylindrical. The inner diameter and diameter of the cylindrical section 200 are consistent with those of the inner cylindrical portion 110. The main structural shape of the fixed ring end 100 and the cylindrical section 200 is as shown above, and the specific connection shape of the fixed ring end 100 and the cylindrical section 200 refers to the existing conventional settings. A first silver coating 300 is provided on the inner wall and outer wall of the end of the cylindrical section 200 away from the fixing ring end 100 , and a second silver coating 400 is provided on all surfaces of the outer cylindrical portion 130 .

[0037] During the plating process, when processing the first silver plating layer 300 on the tubular section 200 , due to the tubular shape of the tubular section 200 , there is no problem of air pressure inhibiting the plating solution from entering the tubular section 200 .

[0038] During the processing of the second silver plating layer 400 on the fixed ring end 100, the outer cylindrical portion 130 is positioned upward, allowing the plating solution to flow smoothly into the outer cylindrical portion 130, thereby facilitating the plating process. After the processing of the first silver plating layer 300 and the second silver plating layer 400 is completed, the cylindrical section 200 is friction-welded to the inner cylindrical portion 110 at their end surfaces to form a connection.

[0039] In summary, the fixed ring end 100 and the cylindrical section 200 are arranged to be connected by friction welding, so that the two can be processed independently and conveniently, and the plating can achieve efficient and high-quality processing; during the processing of the first silver plating layer 300 on the cylindrical section 200, due to the cylindrical shape of the cylindrical section 200, the plating solution can smoothly enter the interior of the cylindrical section 200; during the processing of the second silver plating layer 400 on the fixed ring end 100, the outer end cylindrical portion 130 is arranged upward, so that the plating solution can smoothly enter the outer end cylindrical portion 130, so that the plating can be combed and processed.

[0040] Reference Figures 7 to 8 In one embodiment, a channel 121 passes through the central axis of the columnar portion 120 .

[0041] In this embodiment, the gas pressure is balanced through the channel 121, which facilitates the execution of the chemical plating process.

[0042] Reference Figures 5 to 6 In one embodiment, the second silver plating layer 400 also covers the outer surface of the columnar portion 120 and the outer surface of the inner end cylindrical portion 110 .

[0043] In this embodiment, the second silver plating layer 400 is processed on the outer surface of the columnar portion 120 and the outer surface of the inner cylindrical portion 110 in the same manner. For example, after the inner end of the inner cylindrical portion 110 is supported in the plating tank, the entire chemical plating process is completed. Since the inner end of the inner cylindrical portion 110 plays a supporting role, the plating solution will not enter this position.

[0044] In one embodiment, the length of the inner cylindrical portion 110 is 40% to 60% of the total length of the copper conductive rod.

[0045] In this embodiment, the length of the inner cylindrical portion 110 is increased to facilitate processing, and the length of the cylindrical section 200 is shortened to facilitate extrusion molding or cold heading molding.

[0046] In one embodiment, the length of the inner cylindrical portion 110 is 5% to 10% of the total length of the copper conductive rod.

[0047] In this embodiment, considering that a longer fixed ring end 100 increases the cost of the coating process, the length of the inner cylindrical portion 110 is reduced, thereby increasing the length of the cylindrical section 200. The above preferred conditions for the length of the inner cylindrical portion 110 are based on the premise that the processing cost of the cylindrical section 200 is low.

[0048] In one embodiment, a thread structure is formed on the inner wall of the end of the cylindrical section 200 away from the fixing ring end 100 .

[0049] In this embodiment, an internal thread structure is added at the connection position of the cylindrical section 200 to meet the usage conditions of some scenarios.

[0050] In one embodiment, a thread structure is formed on the inner wall of the outer cylindrical portion 130 at one end away from the columnar portion 120 .

[0051] In this embodiment, an internal thread structure is added at the connection position of the outer end cylindrical portion 130 to meet the usage conditions of some scenarios.

[0052] In one embodiment, the thickness of the first silver plating layer 300 and the second silver plating layer 400 is between 3 and 10 micrometers.

[0053] In this embodiment, suitable coating ranges of the first silver coating layer 300 and the second silver coating layer 400 are provided, which can comprehensively consider processing efficiency, processing cost and conductive performance.

[0054] In one embodiment, the cylindrical section 200 and the inner cylindrical portion 110 are rotationally friction welded on their end surfaces.

[0055] In this embodiment, the connection strength is ensured by limiting the specific manner of friction welding connection between the cylindrical section 200 and the inner end cylindrical portion 110 .

[0056] In one embodiment, the cylindrical section 200 is connected to the inner cylindrical portion 110 by friction stir welding in the circumferential direction at the connection position.

[0057] In this embodiment, the friction stir welding is used to eliminate impurities in the circumferential direction at the connection position between the cylindrical section 200 and the inner end cylindrical portion 110, and the friction stir welding connection is also achieved.

[0058] To sum up, the copper conductive rod for an environmental protection cabinet provided by the present invention is configured to be friction-welded with the fixed ring end 100 and the cylindrical section 200, so that the two can be independently and conveniently processed while the plating can achieve efficient and high-quality processing; during the processing of the first silver plating layer 300 on the cylindrical section 200, due to the cylindrical shape of the cylindrical section 200, the plating solution can smoothly enter the interior of the cylindrical section 200; during the processing of the second silver plating layer 400 on the fixed ring end 100, the outer end cylindrical portion 130 is configured upward, so that the plating solution can smoothly enter the outer end cylindrical portion 130, so that the plating can be combed and processed.
