Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, and in particular to an outdoor power distribution equipment with a lightning protection structure. Background Technology

[0002] In outdoor power distribution systems, surge arresters are usually installed inside outdoor power distribution devices as key protective equipment to resist the damage caused by lightning strikes. Considering the convenience of equipment maintenance, some maintenance personnel will choose to install surge arresters near the entrance and exit of the cabinet to facilitate regular inspections and performance tests.

[0003] However, this installation method poses a significant safety hazard—because surge arresters may experience abnormal discharges, explosions, or other sudden events during operation, placing them near doorways significantly increases the risk of accidental injury to operators during maintenance. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an outdoor power distribution device with a lightning protection structure, thereby improving the safety of lightning arresters installed in power distribution cabinets.

[0005] The technical solution of this utility model is as follows:

[0006] An outdoor power distribution device with a lightning protection structure includes a power distribution cabinet, a door installed on the open side of the power distribution cabinet, and a mounting block fixed on the side wall of the power distribution cabinet near the door, with a lightning arrester installed on the mounting block;

[0007] An insulating shell for housing a surge arrester is slidably connected to one side of the mounting block. The insulating shell is a transparent acrylic sheet. A handle is fixed to the side of the insulating shell away from the mounting block. A snap-fit ​​assembly is installed on the insulating shell to stably snap the insulating shell onto the outer wall of the mounting block.

[0008] Optionally, the mounting block has an L-shaped cross-section, the insulating shell has a C-shaped cross-section, and sliding sleeves are fixed at both ends of the inner wall of the insulating shell. The sliding sleeves are integrally formed with the insulating shell, and the two sliding sleeves are slidably connected to the upper and lower ends of the mounting block, respectively.

[0009] Optionally, the snap-fit ​​assembly includes spring tabs fixed on both sides of the sliding sleeve, the spring tabs being pressed towards the side closer to the mounting block and pressed tightly against the outer wall of the mounting block.

[0010] Optionally, the mounting block has slots on both sides. When the insulating shell is close to the mounting block, it is in a state of covering the surge arrester. When the insulating shell is in the state of covering, the side of the spring piece close to the mounting block is inserted into the slot.

[0011] Optionally, on both sides of the mounting block, a number of equally spaced protrusions are formed on the travel trajectory of the spring piece, and when the spring piece passes through the protrusions, the spring piece is in close contact with the outer wall of the protrusions.

[0012] The beneficial effects of this utility model are as follows:

[0013] The insulating enclosure protecting the surge arrester effectively prevents accidental injury to operators due to operational errors. The design of the insulating enclosure and the mounting block, which combines sliding and snap-fit ​​components, allows maintenance personnel to easily expose the surge arrester by simply sliding the insulating enclosure during regular inspections and performance tests, facilitating maintenance. The transparent acrylic insulating enclosure also allows maintenance personnel to visually inspect the surge arrester's operating status without opening the enclosure, reducing unnecessary operations and improving maintenance efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] An outdoor power distribution device with a lightning protection structure includes a power distribution cabinet 1, a door installed on the open side of the power distribution cabinet 1, an mounting block 2 fixed on the side wall of the power distribution cabinet 1 near the door, and a lightning arrester 3 installed on the mounting block 2.

[0021] An insulating shell 4 for housing the surge arrester 3 is slidably connected to one side of the mounting block 2. The insulating shell 4 is a transparent acrylic sheet. A handle 9 is fixed on the side of the insulating shell 4 away from the mounting block 2. A snap-fit ​​assembly is installed on the insulating shell 4. The snap-fit ​​assembly is used to stably snap the insulating shell 4 onto the outer wall of the mounting block 2.

[0022] The mounting block 2 has an L-shaped cross section, and the insulating shell 4 has a C-shaped cross section. Sliding sleeves 5 are fixed at both the upper and lower ends of the inner wall of the insulating shell 4. The sliding sleeves 5 are integrally formed with the insulating shell 4, and the two sliding sleeves 5 are slidably connected to the upper and lower ends of the mounting block 2 respectively.

[0023] The snap-fit ​​assembly includes spring pieces 6 fixed on both sides of the sliding sleeve 5. The spring pieces 6 are pressed against the outer wall of the mounting block 2 and pressed against the side of the mounting block 2. The mounting block 2 has slots 7 on both sides. When the insulating shell 4 is close to the mounting block 2, it is in the state of covering the surge arrester 3. When the insulating shell 4 is in the state of covering, the spring piece 6 close to the mounting block 2 is snapped into the slot 7. On both sides of the mounting block 2, a number of equally spaced protrusions 8 are formed on the travel trajectory of the spring piece 6. When the spring piece 6 passes the protrusions 8, the spring piece 6 is pressed against the outer wall of the protrusions 8.

[0024] Working principle of this utility model:

[0025] In daily use, the insulating shell 4 protects the surge arrester 3. That is, the insulating shell 4 is located on the side close to the mounting block 2 and is in the state of covering the surge arrester 3. At this time, the side of the spring piece 6 close to the mounting block 2 is stuck in the slot 7 to prevent the insulating shell 4 from sliding accidentally. The covering state of the insulating shell 4 can effectively prevent operators from suffering accidental injury due to operation errors.

[0026] Hold the handle 9 to pull out the insulating shell 4 and remove it; when pulling out the insulating shell 4, the sliding sleeve 5 will slide on the outer wall of the mounting block 2. There are several equally spaced protrusions 8 on both sides of the mounting block 2 corresponding to the travel path of the spring piece 6. When the spring piece 6 passes the protrusion 8, it will stick to the outer wall of the protrusion 8. This not only helps the spring piece 6 to remain stable during the sliding process, but also increases the friction between the spring piece 6 and the mounting block 2 to a certain extent, making the fixing of the insulating shell 4 more stable.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
