Description

Technical Field

[0001] This utility model relates to a high-voltage supporting component, specifically a conductive rod for high-voltage equipment. Background Technology

[0002] Conductive rods for high-voltage equipment are key components in power systems, primarily functioning to transmit and distribute high voltage and high current, ensuring efficient and stable power delivery. They connect transformers, circuit breakers, disconnectors, and other equipment to form complete circuit paths, while also providing mechanical support and electrical insulation. Made from highly conductive materials, they effectively reduce resistance loss, minimize heat generation, and enhance current carrying capacity. Their structural design incorporates excellent anti-corona and arc-resistance properties, and surface treatment processes further reduce contact resistance and prevent localized overheating. Compared to traditional conductors, conductive rods possess high mechanical strength and rigidity, enabling them to adapt to complex installation environments and maintain shape stability during long-term operation, reducing the risk of vibration fatigue. However, when used in high-voltage equipment, many conductive rods rely on fixed dimensions for assembly and use.

[0003] In the prior art, 202322838695.8 describes a conductive rod for low-voltage switchgear. This utility model discloses a conductive rod for low-voltage switchgear, comprising a first conductive rod, a second conductive rod inserted into the first conductive rod, a first sheath disposed on the outside of the first conductive rod, and a second sheath disposed on the outside of the second conductive rod. A first mating sleeve is fixedly connected to the outside of the first sheath. A second sealing groove is provided on one side of the first mating sleeve, and a second sealing ring is installed inside the second sealing groove. A positioning sleeve is integrally formed at one end of the second sheath, and a first sealing groove is provided on the outside of the positioning sleeve, with a first sealing ring installed inside the first sealing groove. This utility model achieves a double sealing effect through the first and second mating sleeves providing a first layer of sealing, and the first sealing ring providing a second layer of sealing. This improves the sealing performance at the connection between the first and second conductive rods, preventing moisture from entering the low-voltage switchgear along the first conductive rod and ensuring the normal operation of the electrical equipment inside the low-voltage switchgear.

[0004] The conductive rod in the prior art can prevent moisture from entering the low-voltage switchgear along the first conductive rod, ensuring the normal operation of the electrical equipment in the low-voltage switchgear. However, when in use, the size of the conductive rod is fixed and cannot be adapted to local conductive distance adjustments. Utility Model Content

[0005] To overcome the shortcomings of existing technologies where the conductive distance is difficult to adjust, this utility model provides a conductive rod for high-voltage equipment.

[0006] This utility model is achieved using the following technical solution: a conductive rod for high-voltage equipment, comprising a main conductive rod, a front conductive connection end and a rear conductive connection end, a hollow structure inside the main conductive rod, a movable cavity inside the hollow structure, a sub-conductive rod installed in the movable cavity for moving the conductive rod, the sub-conductive rod being inserted into the movable cavity, a position adjustment component for controlling the movement of the sub-conductive rod on the main conductive rod, the position adjustment component being a position adjustment chuck, the position adjustment chuck being fitted onto the main conductive rod, the position adjustment chuck having a circular hole, a position adjustment screw being fitted into the circular hole, a front chuck being fitted onto the position adjustment screw, the front chuck being fitted onto the sub-conductive rod.

[0007] The sub-conductive rod is fitted with a front chuck, the front chuck is provided with a top boss, the top boss is provided with an adapter round hole, and an adjustment screw is inserted between the adapter round hole and the round hole.

[0008] A locking pin is provided on the top boss, and the locking pin is inserted into the position adjustment screw to fix the top boss and the position adjustment screw.

[0009] The front conductive connection end is provided with an assembly slot for assembly, and the assembly slot is provided with an assembly side hole for assembling high-voltage equipment.

[0010] The rear conductive connection end is located on one side of the main conductive rod, and a conductive plug is provided on the rear conductive connection end. The conductive plug is a wide-headed and flat conductive plug.

[0011] A limiting component is provided between the main conductive rod and the sub-conductive rod. The limiting component is a limiting ring, and the limiting ring is provided with a limiting boss.

[0012] The limiting bosses are located on both sides of the limiting ring, and the limiting bosses are lateral limiting bosses.

[0013] Compared to existing technologies, the main conductive rod incorporates a movable sub-conductive rod, which, together with the position adjustment chuck and position adjustment screw mechanism, enables flexible adjustment of the conductive rod's length. This allows it to adapt to the installation requirements of high-voltage equipment with different spacing, greatly enhancing the product's versatility. The cooperation structure between the position adjustment screw and the locking pin ensures the stability of the sub-conductive rod after positioning, effectively preventing displacement caused by vibration or temperature changes and guaranteeing long-term stable conductivity.

[0014] The mounting slots and side holes on the front conductive connection end facilitate the assembly of the conductive rod, simplifying the on-site installation process, reducing the difficulty of manual operation and the risk of assembly errors, while improving connection reliability. The rear conductive connection end adopts a wide-headed flat conductive plate to increase the contact area and optimize current distribution. The limiting ring between the main conductive rod and the sub-conductive rod is equipped with a transverse limiting boss, which allows axial adjustment while limiting radial displacement. This dual limiting mechanism ensures both adjustment flexibility and prevents equipment malfunction, significantly improving the safety of equipment operation. Attached Figure Description
