Description

Technical Field

[0001] This utility model relates to an electrical shielding component, specifically a corrosion-resistant shielding cover. Background Technology

[0002] Protecting personnel and equipment safety: Shielding covers effectively isolate high-voltage arcs and electromagnetic waves from harm to surrounding personnel and equipment, avoiding the risk of electric shock or electromagnetic radiation interference. By reducing external electromagnetic interference and mutual interference between internal components, shielding covers ensure the normal operation of electrical components in high-voltage environments, improving equipment operating efficiency. In specific scenarios such as vacuum interrupters, shielding covers can adjust the electric field distribution, avoiding local breakdown caused by electric field concentration, thereby enhancing insulation performance. Shielding covers are typically made of metallic conductor materials, utilizing the reflection and absorption characteristics of metals to form a closed or nearly closed cavity. According to the Faraday cage principle, external electromagnetic fields induce charges on the metal surface, but the internal electric field strength is significantly weakened or even approaches zero, thus blocking electromagnetic interference.

[0003] In the prior art, document 201710567712.5 describes an exposed shielding cover device for accelerating heat dissipation in a vacuum interrupter. This invention proposes such a device, comprising a ceramic shell, a shielding cover, an upper cover plate, and a lower cover plate. The upper and lower cover plates are respectively located at both ends of the ceramic shell and respectively fix a stationary contact and a moving contact. The shielding cover is located inside the ceramic shell. The ceramic shell is a hollow cylinder with a gradually decreasing radius along its axial direction, the radius decreasing from the middle to both ends. The thickness of the middle portion of the cylinder is less than the thickness of the two ends. This invention reduces the internal electric field strength, thus reducing heat generation, and also accelerates heat dissipation in the vacuum interrupter through heat conduction via a vacuum superconducting heat dissipation pipe.

[0004] Although existing shielding covers use vacuum superconducting heat pipes to conduct heat and accelerate the heat dissipation of the vacuum interrupter, they also cannot achieve efficient assembly between the two shielding covers. Utility Model Content

[0005] To overcome the inconvenience of assembling multiple shielding covers in existing technologies, this utility model provides a corrosion-resistant shielding cover.

[0006] This utility model is achieved using the following technical solution: a corrosion-resistant shielding cover, comprising a first shielding cover and a second shielding cover, with an assembly component between the first and second shielding covers. The first shielding cover has a first shielding space, and the second shielding cover has a second shielding space. A partition plate is provided between the first and second shielding spaces for shielding electrical components from high-voltage arcs. The first shielding cover has an assembly flange for assembling with other electrical components, and the assembly flange has an assembly hole. A locking bolt for further tightening is provided in the assembly hole. The assembly component is an assembly module for further assembling the first and second shielding covers. The assembly module has assembly grooves located on both sides of the assembly module, and the first and second shielding covers are inserted into the assembly grooves.

[0007] The assembly module is provided with a locking component, which is a locking long screw. The first shield and the second shield are provided with threaded holes adapted to the locking long screw.

[0008] The assembly module is provided with a hollow groove, and the first shield and the second shield are provided with an adapter groove. A partition plate is inserted into the hollow groove.

[0009] The partition plate is inserted into the hollow groove, and the partition plate is inserted into the adapter groove along the hollow groove. The partition plate is provided with a lifting and rotating component, which is a lifting insertion hole.

[0010] The first shielding cover is provided with an internal reinforcing plate, which is a shielding reinforcement plate. The first shielding cover is provided with an assembly side groove, and the reinforcing plate is inserted into the assembly side groove.

[0011] The second shielding cover is provided with a corrosion-resistant component, which is a corrosion-resistant galvanized sheet, and the corrosion-resistant galvanized sheet is located on the outside of the second shielding cover.

[0012] The second shield is provided with a suspension on its outer side, and the suspension is provided with an installation position, on which a corrosion-resistant galvanized sheet is fitted.

[0013] Compared to existing technologies, the first and second shielding covers in the corrosion-resistant shielding cover are connected by assembly modules. The assembly slots and locking screws form a rigid fixing structure, which not only ensures structural stability under high-pressure environments but also simplifies the on-site installation process. The partition plates are precisely positioned through the guide assembly of hollow slots and adapter slots. The lifting holes facilitate operator disassembly and assembly, significantly improving maintenance efficiency. The assembly flanges and locking bolts enhance compatibility with other electrical components, while the reinforcing plates embedded in the assembly side slots specifically strengthen the local structural strength, effectively resisting high-voltage arc impacts.

[0014] The split-type shielding space independently isolates electric arcs through partition plates, ensuring the safety of internal components and avoiding the drawbacks of traditional integral structures that require complete disassembly for maintenance. The external protective layer is formed by suspension installation, effectively blocking the erosion of the main structure by corrosive environments such as humidity and salt spray. The composite structure of the reinforcing plate and the shielding cover body improves the pressure resistance while maintaining lightweight, and can maintain stable electrical performance and mechanical integrity under harsh working conditions such as high pressure and corrosion.
