Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a spliced box-type transformer shell. Background Technique

[0002] A box-type transformer is a prefabricated substation or prefabricated power distribution equipment, which integrates a transformer, high and low voltage control equipment. The box-type transformer usually consists of a high-voltage switch control room, a transformer room, and a low-voltage switch control room. All components are installed in a completely enclosed steel box structure. The box-type transformer is arranged according to a certain wiring scheme, realizing a factory prefabricated indoor or outdoor compact power distribution solution. It is widely used in urban power grids, residential areas, large construction sites, mining enterprises and other places, especially suitable for occasions with limited space or the need for rapid deployment.

[0003] In the utility model patent with the patent announcement number CN210430577U, its entire main structure is jointly constituted by a first splicing shell, a second splicing shell, a top fixing shell, a fixing base and two third splicing shells. And after these plate layers are fixedly connected through clamping by a first clamping block, a second clamping block, a third clamping block, a fourth clamping block, a first groove, a second groove, a fourth groove and a fifth groove, they are reinforced by a plurality of fixing frames and bolts. So that when the whole device is transported, it only needs to remove the fixing structure and loosen the clamping position, and then it can be transported separately. This solves the problem that the traditional device needs to find a large enough vehicle for overall transportation during transportation. Although this method can reduce the transportation space and improve the transportation convenience, there is also a problem that the spliced shell cannot be ventilated and cooled on the premise of ensuring that rain and foreign objects do not enter, and the overall shell is not conducive to actual use.

[0004] Therefore, it is necessary to provide a spliced box-type transformer shell to solve the above technical problems. Content of the Utility Model

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a spliced box-type transformer shell to solve the problem that although the existing spliced shell can reduce the transportation space and improve the transportation convenience, there is also a problem that the spliced shell cannot be ventilated and cooled on the premise of ensuring that rain and foreign objects do not enter, and the overall shell is not conducive to actual use.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0007] A spliced box-type transformer shell, comprising: a front end plate, a top plate, a side plate, a bottom plate;

[0008] The front panel, top panel, side panels, and bottom panel are all installed and connected by bolts for positioning, jointly forming the entire housing. Installation rails are installed at the rear ends of the top panel and the bottom panel. The installation rails are arranged opposite to each other vertically. A rear panel group is installed inside the installation rails. The rear panel group is formed by splicing multiple groups of plates.

[0009] In one embodiment, support rods are installed at the four corners of the top surface of the bottom panel. Reinforcing rods are installed on the side surfaces of the support rods facing the side panels. Two groups of reinforcing rods are provided at intervals vertically. Threaded holes are provided on the surfaces of the reinforcing rods facing the side panels. A sleeve plate is installed on the outer side surface of the side panel.

[0010] In one embodiment, positioning plates are provided on both sides of the rear panel group. Positioning holes are provided on the positioning plates facing the side panels. The positioning holes are inserted into positioning rods located on the inner side surfaces of the side panels. Multiple groups of connecting plates are installed between the positioning plates. Rectangular grooves are provided on the right side surfaces of the connecting plates and the positioning plates. An insertion plate is installed on the left side of the connecting plate. An intermittent groove is provided at the left end of the insertion plate. Communication grooves are provided on the front and rear end surfaces of the connecting plate. The communication grooves are of a semi-circular structure. Flow guide grooves are provided on the inner walls of the rectangular grooves of the connecting plate. The flow guide grooves are of a semi-cylindrical structure, and multiple groups of them are arranged side by side vertically.

[0011] In one embodiment, the flow guide grooves are inclined downward from left to right.

[0012] In one embodiment, sealant is injected at the adjacent connection parts of the connecting plates.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) In the present utility model, the single-side side panel, bottom panel, top panel, and front panel are installed by screwing. The positioning plates are first placed inside the installation rails and pushed towards the other side panel until the positioning holes are inserted into the positioning rods, providing guiding installation for the subsequent installation of the rear panel group. By pushing the connecting plates towards the installation position, the intermittent groove of the insertion plate abuts against the inner end surface of the previous rectangular groove, making the flow guide grooves, intermittent groove, and communication grooves on both side surfaces of the rectangular groove in a communicating state, successively forming an air flow channel through the outer communication groove, outer rear end surface flow guide groove, intermittent groove, front end surface flow guide groove, and inner communication groove to dissipate heat inside the housing.

[0015] (2) In the present utility model, by inserting the reinforcing rods into the sleeve plates, the threaded holes of the reinforcing rods are fitted with the holes at the ends of the sleeve plates, and bolts are screwed inside to fix the two in connection. The setting of the reinforcing rods helps to improve the stability of the side panels, provides secondary support and fixation for the side panels, reduces the load-bearing of the primary bolt installation, and improves the stability.
