Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically a prefabricated substation. Background Technology

[0002] Prefabricated substations, which integrate high-voltage switchgear, distribution transformers, and low-voltage distribution devices into a closed or semi-closed metal enclosure, are widely used in urban power grid construction, industrial and mining enterprises, and residential communities, providing a convenient and centralized solution for power distribution and use.

[0003] In existing prefabricated substation designs, limited operating space is often a problem when maintenance or repair of internal transformers is required. Due to the fixed enclosure structure, workers find it difficult to carry out maintenance work smoothly in confined spaces, increasing operational difficulty and time costs. Furthermore, some prefabricated substations lack effective protective measures against different weather conditions. During outdoor maintenance, workers are often directly exposed to sun and rain, which not only affects maintenance efficiency but also reduces worker comfort and may even adversely affect the quality of maintenance work and equipment. Therefore, those skilled in the art have provided a prefabricated substation to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated substation to solve the problems that, during maintenance or repair of existing prefabricated substations, the fixed outer shell structure makes it difficult for workers to carry out maintenance work smoothly in a confined space. Furthermore, some prefabricated substations lack effective protective measures in response to different weather conditions, requiring maintenance workers to be exposed to sun and rain during the maintenance process, which affects maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a box-type substation, comprising a base plate and a top plate, wherein a support is vertically connected between the base plate and the top plate, a rear plate is installed on the rear side of the support, a front plate is provided on the front side of the support, and side plates are provided on both sides of the support. A hydraulic rod is vertically installed in the upper middle part of the top plate, and a second connector is installed at the upper output end of the hydraulic rod. A connecting arm is rotatably connected to the end of the second connector. A first connector is installed on the outer wall of the side plate and the front plate. An installation groove is opened in the side plate, and an extension plate is provided in the installation groove. Slots are opened on both sides of the front plate.

[0006] Preferably, the upper end of the side plate is rotatably connected to the side of the top plate, and the upper end of the front plate is rotatably connected to the front side of the top plate.

[0007] Preferably, the end of the connecting arm away from the second connecting member is rotatably connected to the first connecting member. The second connecting member is raised by the extension and retraction of the hydraulic rod. The rise of the second connecting member causes the connecting arm to unfold in a wing-like shape, thereby increasing the maintenance space and facilitating operation by the staff.

[0008] Preferably, the extension plate is slidably inserted into the mounting groove, and one end of the extension plate is inserted into the front plate through a slot.

[0009] Preferably, an arc-shaped groove is formed on one side of the mounting slot, and a lever is installed on one side of the extension plate. The lever passes through the arc-shaped groove. After the extension plate is moved out of the mounting slot, one end of the extension plate is inserted into the slot. This improves the stability of the side plate and the front plate in the flying wing state, while expanding the coverage area of ​​the upper part of the box, thereby forming a sunshade or rainproof effect.

[0010] Preferably, the rear plate has heat dissipation holes and wire through holes.

[0011] Compared with the prior art, this utility model provides a prefabricated substation with the following advantages: Through its design, when maintenance or repair of the transformers inside the prefabricated substation is required, the hydraulic rod extends and retracts, causing the second connecting piece to rise. This, in turn, causes the connecting arm to unfold the two side panels and the front panel in a wing-like shape, effectively increasing the maintenance space and greatly facilitating operation for staff. Simultaneously, the side panels are equipped with mounting slots and extension plates. A lever allows the extension plate to be moved, enabling one end to engage with a slot on the front panel. This enhances the stability of the wing-like configuration of the side and front panels and expands the coverage area of ​​the upper part of the enclosure, providing shade and rain protection, and improving the comfort of maintenance workers during the repair process.
