Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a transformer casing. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a compact complete distribution device that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, energy metering equipment, and reactive power compensation devices in one or several boxes according to a certain wiring scheme. It is widely used in mines, factories, enterprises, oil and gas fields, wind power stations, and other fields because of its easy construction and freedom from geographical restrictions.

[0003] When constructing a box-type substation, the substation frame must be built first, and then the walls, doors, and windows must be assembled on the substation frame. In the existing technology, the substation frame is usually installed by drilling holes and then fixing them with bolts, but the actual operation is still very time-consuming and labor-intensive. Utility Model Content

[0004] In view of this, the utility model provides a transformer housing, which aims to ensure the stability of the transformer housing frame structure while enabling the transformer housing to be quickly constructed.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] A transformer casing comprises a rectangular frame body and box panels that are detachably mounted on each side of the rectangular frame body, and is characterized in that: main beams are provided at the 12 edge positions of the rectangular frame body, and partition beams are arranged on the side and top corresponding to the rectangular frame body, and the partition beams divide the corresponding side of the rectangular frame body into several plate body installation areas; the ends of the two main beams that are vertically connected to each other, and the ends of the partition beams and the sides of the main beams are fixedly connected by locking assemblies; the sides of the main beams and the partition beams are provided with outwardly extending extension panels, and the extension panels located in the same plate body installation area form a rectangular frame, and the box panels are fixedly mounted on the corresponding rectangular frames.

[0007] By adopting the above structure, the rectangular frame structure is stabilized by the locking assembly, and additional punching is effectively avoided, which greatly simplifies the tooling process of the rectangular frame body. The provided extension plate facilitates the rapid positioning and installation of the box panel, thereby speeding up the construction speed of the entire transformer casing.

[0008] Preferably, the partition beam has a strip hole at its end, a mounting groove is provided on one side of the main beam, the locking assembly includes a strip seat fixedly mounted in the strip hole, a connecting pin slidably mounted along its length, the outer end of the connecting pin has a locking plate exposed outside the strip seat, a spring is abutted between the inner end and the strip seat, the spring applies a thrust to keep the connecting pin extending outward, a V-shaped groove is provided on the middle side wall of the connecting pin, an adjustment screw is threadedly connected to one side of the strip seat in the width direction, the inner end of the adjustment screw is located in the V-shaped groove, and is used to limit the connecting pin from being dislodged outward, the outer end of the adjustment screw is exposed on the side of the main beam and the partition beam; the locking plate at the outer end of the connecting pin is mounted in the mounting groove; turning the adjustment screw, under the guidance of one of the inclined surfaces of the V-shaped groove, can force the connecting pin to move inward, overcoming the thrust of the spring, so that the locking plate is tightly connected in the mounting groove. The above structure can achieve stable and fast installation between the main beam and the partition beam.

[0009] Preferably, the bar base has a first groove along its length, with the spring and the connecting pin both disposed within the first groove. The bar base has a first through-hole along its height, with the first through-hole and the first groove interpenetrating each other. A locking pin is inserted into the first through-hole, and the locking pin has a second through-hole aligned with the first groove's forming direction and a second groove aligned with the first through-hole's forming direction. The connecting pin is inserted between the first and second through-holes, with the second groove having an internal thread at its top, and the adjusting screw threadedly mounted within the second groove. The above structure further ensures the stability of the overall structure of the locking assembly through the additional locking pin.

[0010] Preferably, the extension plate has an array of positioning holes, and a positioning nut is provided on the surface of the extension plate located inside the transformer housing. Each positioning nut corresponds to a positioning hole and is fixed to a positioning bracket that is clipped onto the extension plate. This structure allows for quick positioning and installation of the box plate while preventing the nut from falling into the transformer housing.

[0011] Preferably, the positioning bracket includes a horizontal mounting section with a mounting hole defined in the middle thereof. The mounting hole is positioned opposite the threaded hole of the positioning nut. The horizontal mounting section is folded downwardly to form a first clamping portion and a second clamping portion, which are used to securely engage the positioning nut. The bottom of the first clamping portion is folded outward to form a mounting portion. The positioning hole is provided with a stepped structure, and the mounting portion abuts against the stepped structure. This structure ensures stable installation of the positioning nut, thereby facilitating installation of the transformer housing wall module.

[0012] Preferably, the main beams include at least a first main beam, each of which has a limit portion extending along its length, the limit portion being formed adjacent to the extension plate. A second main beam is mounted on the limit portion, and the extension plate extends outward from the second main beam. This structure further ensures the structural strength of the rectangular frame's edges.

[0013] Preferably, a locating pin is provided between the first and second main beams, and the locating pin has a longitudinal locating hole along the vertical direction, through which a reinforcing rod is inserted. This structure ensures the stability of the four circumferential edges of the transformer housing, thereby ensuring a more stable overall frame structure.

[0014] Preferably, the partition beam is provided with an adjustment hole corresponding to the adjustment screw, and the adjustment hole is arranged inside the transformer housing. The above structure can facilitate stable installation between the main beam and the partition beam while ensuring the aesthetics of the entire transformer housing.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The transformer housing provided by the present invention, through the provision of locking components, ensures the stable construction of the rectangular frame while eliminating the need for additional drilling, greatly simplifying the tooling process of the substation frame. The provision of extension plates facilitates the installation of the box panels, further accelerating the construction speed of the entire transformer housing.

[0017] 2. By distributing positioning holes in an array on the extension plate and fixing positioning nuts on each positioning hole, the positioning and installation of the box plate can be very convenient. At the same time, it can also prevent the nuts from falling into the transformer casing, thereby ensuring the normal and stable operation of the internal equipment of the substation.

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] like Figures 1 to 5 As shown, a transformer housing includes a rectangular frame body A and a box panel 1 that is detachably mounted on each side of the rectangular frame body A. Main beams 2 are provided at the 12 edges of the rectangular frame body A. Partition beams 3 are also installed on the corresponding sides and top of the rectangular frame body A. The partition beams 3 can divide the corresponding side of the rectangular frame body A into several plate installation areas B. The ends of the two main beams 2 that are perpendicularly connected to each other, as well as the ends of the partition beams 3 and the sides of the main beams 2, are fixedly connected by locking assemblies C. Outwardly extending extension panels 4 are formed on the sides of the main beams 2 and the partition beams 3. The extension panels 4 located in the same plate installation area B form a rectangular frame, and the box panel 1 is fixedly mounted on the corresponding rectangular frame.

[0030] With this design, the locking assembly A is set up, which not only ensures the stable connection between the two main beams 2 that are vertically connected to each other, and between the partition beam 3 and the main beam 2, but also eliminates the need for additional drilling, greatly simplifying the installation method. The set extension plate 4 also facilitates the installation of the box panel.

[0031] In this embodiment, the locking installation structure between the main beam 2 and the partition beam 3 is as follows: Figures 3 to 7As shown, the partition beams 3 are all provided with strip holes 5 along their length directions, and a hanging groove 6 is provided on one side of the main beam 2. The locking assembly C includes a strip seat 7 fixedly assembled in the strip hole 5, and a connecting pin 8 is provided in the strip seat 7 for sliding installation along its length direction. The outer end of the connecting pin 8 is formed with a locking piece 8a exposed outside the strip seat 7, and a spring 9 is abutted between the inner end and the strip seat 7. The spring 9 applies a thrust to keep the connecting pin 8 extending outward. A V-shaped groove 8b is formed on the middle side wall of the connecting pin 8, and an adjusting screw 10 is threadedly connected to one side of the strip seat 7 in the width direction. The inner end of the adjusting screw 10 is located in the V-shaped groove 8b, which can be used to limit the connecting pin 8 from falling out outward, and the outer end of the adjusting screw 10 is exposed on the sides of the main beam 2 and the partition beam 3, so that the locking assembly C can be limited and clamped at the end of the strip hole 5. The locking piece 8a at the outer end of the connecting pin 8 is hung in the hanging groove 6. By turning the adjusting screw 10, the connecting pin 8 is forced to move inward under the guidance of one of the inclined surfaces of the V-shaped groove 8b, overcoming the thrust of the spring 9, so that the locking piece 8a is firmly connected in the hanging groove 6.

[0032] As for the locking and mounting structure between the main beam 2 and the end portion of the main beam 2, it is the same as the above-mentioned connection method and will not be repeated here.

[0033] Specifically, such as Figure 7 As shown, the strip seat 7 is formed with a first groove 7a along its length direction, the spring 9 and the connecting pin 8 are both arranged in the first groove 7a, and the strip seat 7 is formed with a first through hole 7b along its height direction. The first through hole 7b and the first groove 7a penetrate each other, and a locking pin 11 is passed through the first through hole 7b. The locking pin 11 is provided with a second through hole 11a consistent with the forming direction of the first groove 7a, and a second groove 11b consistent with the forming direction of the first through hole 7b. The connecting pin 8 is passed between the first groove 7a and the second through hole 11a. The top of the second groove 11b is provided with an internal thread, and the adjusting screw 10 is threadedly installed in the second groove 11b.

[0034] In this embodiment, two locking assemblies C are installed at the end of each strip hole 5, and the two main beams 2 perpendicular to each other and the main beam 2 and the partition beam 3 are connected by two locking assemblies C, further ensuring the stability of the rectangular frame body A structure.

[0035] In addition, if Figure 3 and Figure 5 As shown, adjustment holes 15 are formed on the main beam 2 and the partition beam 3 at the positions corresponding to the respective adjustment screws 10, and each adjustment hole 15 is formed inside the transformer casing. Such a design can facilitate the installation between two mutually perpendicular main beams 2 and between the main beam 2 and the partition beam 3, while also ensuring the overall aesthetics of the transformer casing.

[0036] like Figure 9 and Figure 10 As shown, the extension plate 4 is provided with an array of positioning holes 4a, and positioning nuts 12 are mounted on the surface of the extension plate 4 located inside the transformer housing, with each positioning nut 12 corresponding to each positioning hole 4a. In this embodiment, the positioning nuts 12 are clipped onto positioning brackets 13 and fixed to the extension plate 4 via these brackets. This design allows the transformer housing wall module to be mounted on the substation frame by simply tightening the connecting bolts, while also preventing the nuts from falling into the transformer housing.

[0037] Specifically, such as Figure 8 As shown, the positioning bracket 13 has a horizontal mounting section 13a, and a mounting hole 13a1 is formed in the middle of the horizontal mounting section 13a. The mounting hole 13a1 is arranged opposite to the threaded hole of the positioning nut 12. The horizontal mounting section 13a is folded downward in the circumference to form a first clamping portion 13b and a second clamping portion 13d. The first clamping portion 13b and the second clamping portion 13d are both used to clamp and fix the positioning nut 12. A mounting portion 13c is also folded outward at the bottom of the first clamping portion 13b. In this embodiment, a stepped structure 4a1 is formed inside the positioning hole 4a, and the mounting portion 13c rests on the stepped structure 4a1. In the actual installation process, after the rectangular frame body A is built, the positioning bracket 13 is placed in each positioning hole 4a, and the box plate 1 can be rested on the rectangular frame surrounded by the extension plate 4 and the positioning screw 16 can be installed. In addition, the positioning bracket 13 can also be fixed in the positioning hole 4a by welding in advance.

[0038] like Figures 2 to 4 As shown, the main beam 2 includes at least a first main beam 2a, and each first main beam 2a has a limiting portion 2a1 extending along the length direction, and the forming position of the limiting portion 2a1 is located on the adjacent surface of the forming position of the extension plate 4. In this embodiment, except for the four edges at the bottom of the rectangular frame body A, the limiting portions 2a1 of the first main beam 2a corresponding to the remaining eight edges are all clamped with the second main beam 2b, and the second main beam 2b also has an extension plate 4 extending outward. Such a design can ensure the structural strength of the entire rectangular frame body A.

[0039] like Figure 2 As shown, a locating pin 14 is installed between the first main beam 2a and the second main beam 2b corresponding to the four vertical edges of the rectangular frame body A. In this embodiment, two locating pins 14 are installed between the first main beam 2a and the second main beam 2b on the same edge. Both locating pins 14 are formed with longitudinal locating holes 14a in the vertical direction. The longitudinal locating holes 14a are used to pass reinforcing rods. With this design, the structural stability of the four vertical edges of the transformer casing frame can be ensured by the locating pins 14, and the reinforcing rod passed between the two locating pins 14 further ensures the stability of the overall structure of the rectangular frame body A.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
