Description

Technical Field

[0001] This application relates to the technical field of conductive rods, and in particular to a conductive rod for use in low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear is a type of low-voltage electrical equipment used in power systems. Its main function is to switch, control, and protect electrical equipment during power generation, transmission, distribution, and energy conversion. Low-voltage switchgear typically relies on conductive rods to connect to external cables. Specifically, one conductive rod is installed on the cabinet and connected to the internal cables, while another conductive rod is connected to the external cables. The two conductive rods are then joined together to connect the low-voltage switchgear to the external cables. Multiple sets of conductive rods can be installed. However, existing low-voltage switchgear conductive rods have certain drawbacks. Some conductive rods have poor conductivity, generating significant resistance during current transmission, leading to increased energy loss. This not only wastes energy but may also cause the conductive rods to overheat, affecting their lifespan and the safe operation of the switchgear. Furthermore, some conductive rod connections are not secure enough, easily loosening when the switchgear is subjected to vibration or impact. This increases contact resistance, further exacerbating overheating and potentially causing electrical faults. Utility Model Content

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a conductive rod for use in low-voltage switchgear. (Refer to...) Figure 1-3 A conductive rod for low-voltage switchgear mainly consists of a rod body 1, a connecting end 4, a heat dissipation structure, and a protective layer 2.

[0020] The pole 1 is made of a high-conductivity metal material, such as copper, to ensure low resistance during current transmission and reduce power loss. The cross-section of the pole 1 is circular, and the selection is made according to the actual current carrying requirements to meet the usage requirements of low-voltage switchgear of different specifications.

[0021] The connecting end 4 is located at one end of the rod body 1. A threaded protrusion 5 is provided on the side wall of the connecting end 4. A threaded groove 6 is provided at one end of the inner side wall of the rod body 1 to engage with the threaded protrusion 5. The connecting end 4 is connected by a thread to ensure a stable and reliable connection that is not easy to loosen.

[0022] A heat dissipation structure is set on the surface of the rod 1 to enhance the heat dissipation effect. The heat dissipation structure includes multiple heat dissipation slots 3, which are opened on the surface of the rod 1. Heat is carried away by air convection, effectively reducing the temperature of the rod 1. The design of the heat dissipation structure can ensure that the heat can be dissipated in time when the conductive rod is running under high load, avoiding performance impact due to overheating.

[0023] The protective layer 2 covers the surface of the rod body 1 to improve the corrosion resistance of the conductive rod. The protective layer 2 is made of corrosion-resistant materials, such as epoxy resin coating, which can effectively isolate the rod body 1 from corrosive substances in the external environment and extend the service life of the conductive rod.

[0024] Multiple reinforcing ribs 7 are provided inside the rod body 1 to enhance the mechanical strength of the rod body 1 and prevent deformation during installation or use.

[0025] The surface of heat sink 3 is blackened to improve its heat dissipation performance.

[0026] The implementation principle of a conductive rod for low-voltage switchgear in this application embodiment is as follows: When using the conductive rod for low-voltage switchgear, firstly, select a suitable conductive rod according to the specific specifications and electrical connection requirements of the low-voltage switchgear. Then, screw the threaded protrusion 5 of the connecting end 4 into the corresponding threaded groove 6 inside the rod body 1, tightening it to the specified torque to ensure a secure connection. During installation, care should be taken to avoid damaging the rod body 1, especially the heat dissipation structure and protective layer 2. After installation, check whether the connecting end 4 is secure to ensure that the conductive rod will not loosen during operation. During the operation of the low-voltage switchgear, the conductive rod begins to transmit current. Because the rod body 1 uses a high-conductivity material, the power loss is small. At the same time, the heat dissipation structure begins to function; the heat dissipation groove 3 dissipates the heat generated by the rod body 1 through air convection, keeping the temperature of the rod body 1 within the normal range. The protective layer 2 protects the rod body 1 from external corrosive substances, extending the service life of the conductive rod. Regularly inspect and maintain the conductive rod, observing whether the connecting end 4 is loose, whether the protective layer 2 is damaged, and whether the heat dissipation structure is blocked. If any problems are found, they should be dealt with promptly, such as retightening the connection end 4, repairing the protective layer 2, or cleaning the heat dissipation structure, to ensure that the conductive rod always performs well.
