Description

Technical Field

[0001] This utility model belongs to the field of disconnector technology, specifically relating to an outdoor high-voltage disconnector. Background Technology

[0002] As high-voltage transmission networks expand into complex outdoor terrains, the environmental adaptability and structural reliability of high-voltage disconnectors face higher demands. Traditional outdoor disconnectors often use a single base for fixation, which is prone to base loosening, support structure deformation, or even toppling in harsh environments such as strong winds, earthquakes, or freeze-thaw cycles, leading to decreased insulation performance or short-circuit risks. Existing technologies sometimes improve stability by increasing base thickness or adding external supports, but these methods suffer from complex installation, material redundancy, and an inability to effectively distribute dynamic loads. Furthermore, conventional fixing methods are prone to stress concentration and base plate cracking in soft soil foundations or areas with frequent vibrations, further reducing equipment lifespan. Therefore, there is an urgent need for a high-voltage disconnector that balances lightweight structure, overturning resistance, and rapid installation to meet the long-term challenges of complex outdoor conditions. Utility Model Content

[0003] The main purpose of this utility model is to provide an outdoor high-voltage disconnector that integrates a fixed base, a reinforcing plate, and a support plate, breaking through the bottlenecks of insufficient rigidity and poor installation adaptability of traditional outdoor high-voltage disconnectors.

[0004] To achieve the above objectives, this utility model provides an outdoor high-voltage disconnector, which includes a disconnector body. A fixed base is provided at the bottom of the disconnector body. A mounting base plate is symmetrically arranged on the left and right sides below the fixed base. A vertical connecting reinforcement plate is provided on the mounting base plate. The bottom of the vertical connecting reinforcement plate is connected to the mounting base plate, and the vertical connecting reinforcement plate is connected to the side of the fixed base.

[0005] The outdoor high-voltage disconnector provided by this utility model forms a dual-support point layout by setting a fixed base at the bottom of the disconnector body and symmetrical mounting plates on both sides. This disperses the weight of the equipment and external loads (such as wind bending moments), reducing the risk of stress concentration at single points. A vertically connected reinforcing plate is welded vertically to the mounting plate and connected to the side of the fixed base, forming an "L-shaped" anti-bending structure. This enhances the connection rigidity between the base and the mounting plate, suppressing structural fatigue caused by lateral vibration. This design significantly improves the installation stability of the disconnector while ensuring lightweight design.

[0006] In one possible implementation, the height of the vertical connecting reinforcement plate is greater than the height of the fixed base. Designing the height of the vertical connecting reinforcement plate to be greater than the height of the fixed base allows the top of the vertical connecting reinforcement plate to extend to the upper-middle part of the base side, creating a "cantilever beam" effect. When the equipment is subjected to lateral forces (such as strong wind impact), the contact surface between the top of the reinforcement plate and the base generates a counter-torque, counteracting the overturning tendency. Simultaneously, the extended lever arm reduces the shear stress at the base root, preventing weld cracking. This structure is particularly suitable for high-tower installations and can withstand greater wind load offsets.

[0007] In one possible implementation, a support plate is provided below the fixed base, with its top end connected to the bottom of the fixed base and its bottom end resting on the surface of the mounting base plate. Adding a support plate below the fixed base, with its top end connected to the bottom of the base and its bottom end abutting the surface of the mounting base plate, forms a "vertical pressure-bearing column." This structure directly transmits the longitudinal pressure borne by the base (such as the equipment's own weight and snow load) to the mounting base plate, preventing deformation of the base bottom due to suspension.

[0008] In one possible implementation, one end of the support plate is connected to the vertical connecting reinforcement plate. Connecting one end of the support plate to the vertical connecting reinforcement plate eliminates the gap between the support plate and the reinforcement plate through a rigid joint, allowing both to work together to bear the load.

[0009] In one possible implementation, the mounting base plate is provided with bolt fixing holes. Using bolts for fixing and installation is more convenient and faster. Attached Figure Description

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0014] See attached diagram. Figure 1 , Figure 1 This is a schematic diagram of an outdoor high-voltage disconnector provided by this utility model, as shown below. Figure 1 As shown, the present invention provides an outdoor high-voltage disconnector including a disconnector body 1, a fixed base 2 at the bottom of the disconnector body 1, and mounting base plates 3 symmetrically arranged on the left and right sides below the fixed base 2. Vertical connecting reinforcement plates 4 are provided on the mounting base plates 3, the bottom of the vertical connecting reinforcement plates 4 is connected to the mounting base plates 3, and the vertical connecting reinforcement plates 4 are connected to the side of the fixed base 2.

[0015] The outdoor high-voltage disconnector provided by this utility model forms a dual-support point layout by setting a fixed base 2 at the bottom of the disconnector body 1 and symmetrical mounting base plates 3 on both sides. This disperses the weight of the equipment and external loads (such as wind bending moments), reducing the risk of stress concentration at a single point. The vertically connected reinforcing plate 4 is welded vertically to the mounting base plate 3 and connected to the side of the fixed base 2, forming an "L-shaped" anti-bending structure, which enhances the connection rigidity between the base and the base plate and suppresses structural fatigue caused by lateral vibration. This design significantly improves the installation stability of the disconnector while ensuring lightweight design.

[0016] In one possible implementation, the height of the vertical connecting reinforcing plate 4 is greater than the height of the fixed base 2. Designing the height of the vertical connecting reinforcing plate 4 to be greater than the height of the fixed base 2 allows the top of the vertical connecting reinforcing plate 4 to extend to the upper-middle part of the base side, forming a "cantilever beam" effect. When the equipment is subjected to lateral forces (such as strong wind impact), the contact surface between the top of the reinforcing plate and the base generates a counter-torque, counteracting the overturning tendency. Simultaneously, the extended lever arm reduces the shear stress at the base root, preventing weld cracking. This structure is particularly suitable for high-tower installations and can withstand greater wind load offsets.

[0017] In one possible implementation, a support plate 5 is provided below the fixed base 2. The top end of the support plate 5 is connected to the bottom of the fixed base 2, and the bottom end of the support plate 5 is disposed on the surface of the mounting base plate 3. Adding a support plate 5 below the fixed base 2, with its top end connected to the bottom of the base and its bottom end attached to the surface of the mounting base plate 3, forms a "vertical pressure-bearing column." This structure directly transmits the longitudinal pressure borne by the base (such as the equipment's own weight and snow load) to the mounting base plate 3, preventing the bottom of the base from deforming due to suspension.

[0018] In one possible implementation, one end of the support plate 5 is connected to the vertical connecting reinforcement plate 4. By connecting one end of the support plate 5 to the vertical connecting reinforcement plate 4, this design eliminates the gap between the support plate 5 and the reinforcement plate through a rigid joint, allowing both to work together to bear the load.

[0019] In one possible implementation, the mounting base plate 3 is provided with bolt fixing holes 6. Using bolts for fixing and installation is more convenient and faster.

[0020] It is worth mentioning that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
