Technical Field

[0001] The utility model relates to the technical field of high-voltage AC disconnectors, in particular to a corrosion-resistant outdoor high-voltage AC disconnector. Background Art

[0002] Outdoor high-voltage AC disconnectors are usually used in power systems, and their main function is to cut off the circuit and ensure safe operation when isolating circuits or equipment.

[0003] However, in the prior art, for some existing outdoor high-voltage AC disconnectors, the conductive plate assembly is usually connected to the pillar through bolts. To prevent rainwater from seeping into the inside through the threaded holes and corroding the components on rainy days, a protective shell is installed through bolts at the connection between the conductive plate and the pillar. However, to prevent gaps between the bolts and the threaded grooves and cause rainwater leakage, the protective shell installed by bolts needs to be replaced regularly. Since the protective shell needs to be frequently replaced to prevent corrosion or other damages, this will not only increase the maintenance cost and the workload of the staff. At the same time, appropriate disassembly and installation tools are required for installation and disassembly. If there are more protective shells to be replaced, it will also increase the labor force of the staff. Summary of the Utility Model

[0029] As Figures 1-3 shown, the present utility model provides a technical solution: a corrosion-resistant outdoor high-voltage AC disconnector, including a support 1, the top of the support 1 is fixedly connected to the bottom of the end 2, a protection mechanism 3 is arranged on the top of the end 2, and an installation mechanism 4 is arranged at the bottom end of the support 1;

[0030] The protection mechanism 3 includes an installation frame 31, a conductive plate assembly 32 is arranged on the inner wall of the installation frame 31, a protection shell 33 is arranged on the top of the installation frame 31, sealing gaskets 34 are arranged on both sides of the protection shell 33, snap rings 35 are arranged on both sides of the bottom of the protection shell 33, fixed shells 36 are arranged on both sides of the installation frame 31, limiting tubes 37 are arranged on one side of the inner walls of the two fixed shells 36, elastic pieces 38 are arranged on the inner walls of the two limiting tubes 37, latch blocks 39 are arranged on the other side of the two elastic pieces 38, and buttons 310 are arranged on the other side of the two latch blocks 39.

[0031] In this embodiment, the bottom of the mounting bracket 31 is fixedly connected to the top end of the support column 1. The conductive plate assembly 32 is fixedly connected to the inner wall of the card slot opened in the mounting bracket 31 by bolts. The inner wall of the protective shell 33 fits with the top surface of the mounting bracket 31. One side of the two sealing gaskets 34 is respectively fixedly connected to both sides of the protective shell 33. The tops of the two snap rings 35 are respectively fixedly connected to both sides of the bottom of the protective shell 33. The inner walls of the card slots opened in the two snap rings 35 are respectively fixedly clamped to the concave parts on the surfaces of the corresponding clamping blocks 39. The two fixed shells 36 are respectively fixedly connected to both sides of the mounting bracket 31. One ends of the two limiting tubes 37 are respectively fixedly connected to one side of the inner wall of the corresponding fixed shell 36. One ends of the two limiting tubes 37 are respectively fixedly connected to the inner wall of the corresponding fixed shell 36. One side of the two elastic pieces 38 is respectively fixedly connected to the inner wall of the corresponding limiting tube 37. The other sides of the two elastic pieces 38 are respectively fixedly connected to one side of the corresponding clamping block 39. One side of the two buttons 310 is respectively fixedly connected to the other side of the corresponding clamping block 39. The above components cooperate with each other; after the protective shell 33 is installed on the mounting bracket 31, the conductive plate is fixed by bolts and pressed tightly against the top of the mounting bracket 31, which can not only ensure that the round hole at the bottom of the protective shell 33 is aligned with the bolt head, thereby effectively preventing rainwater from entering the inside of the mounting bracket 31 through the hole. This design protects the electronic or mechanical components inside the mounting bracket 31 from moisture, thereby extending the service life and reliability of the device. At the same time, the installation process of the protective shell 33 is relatively simple, only need to fix and press tightly according to the steps, and ensure that the snap ring 35 and the clamping block 39 are aligned to form a limit. When disassembling, only need to press the two buttons 310 to release the limit between the clamping block 39 and the snap ring 35, so as to easily remove the protective shell 33. This design also ensures the convenience of maintaining and replacing the protective shell 33, reducing the operation time and labor cost.

[0032] Embodiment 2

[0033] As Figures 1-4 shown, the installation mechanism 4 includes a fixed frame 41. The top of the fixed frame 41 is fixedly connected to the bottom end of the support column 1. Both sides of the fixed frame 41 are fixedly connected with mounting plates 42.

[0034] In this embodiment, the top of the fixed frame 41 is fixedly connected to the bottom end of the support column 1. Both sides of the fixed frame 41 are fixedly connected with mounting plates 42. This structure can not only provide stable installation support. The connection at the bottom end of the support column 1 also ensures the overall stability of the fixed frame 41, while the mounting plates 42 enable the entire device to be firmly fixed to other objects or devices through the fixed frame 41 and are not easily affected by external vibration or impact.

[0035] Working principle:

[0036] As Figures 1-4As shown, when the staff installs it, first, the conductive plate assembly 32 can be fixed to the inner wall of the card slot opened on the mounting bracket 31 through bolts. After being fixed, the inner wall of the protective shell 33 is then pressed against the top surface of the mounting bracket 31. Since two round holes are opened on the bottom inner wall of the protective shell 33, when pressing against the mounting bracket 31, the opened round holes are aligned with the bolt heads, so as to ensure that the inner wall of the protective shell 33 can be completely pressed against the top of the mounting bracket 31. While pressing against the mounting bracket 31, the snap rings 35 installed on both sides of the bottom of the protective shell 33 need to be aligned with the card slots opened on the top of the fixed shell 36, so that the snap rings 35 pass through the card slots opened on the fixed shell 36 and are clamped with the corresponding latch blocks 39 to form a limit, and thus the installation of the protective shell 33 can be completed. The installation of the protective shell 33 can prevent rainwater from seeping into the mounting bracket 31 through the threaded holes on rainy days and corroding the internal components. When disassembling, only need to press two buttons 310 at the same time. When the buttons 310 are pressed, they will push the latch blocks 39 to squeeze the springs. When the springs are squeezed, they will deform and contract. During the deformation and contraction process of the springs, the movement of the latch blocks 39 will be realized, so that the limit between the latch blocks 39 and the snap rings 35 is released, and the staff can remove the protective shell 33.

Therefore, any omission, modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
