Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a three-phase combined transformer. Background Art

[0002] The three-phase combined transformer is a kind of small transformer. The small transformer mainly refers to the transformer with a single-phase capacity of less than 20kV·A and a three-phase capacity of less than 50kV·A. The characteristics of the small transformer are small size, low cost and less wire. The load rate and utilization rate of the small transformer are generally low. The inductive load it carries is generally not capacitively compensated. The three-phase combined transformer is connected to the wire connector to amplify or compress the voltage to the voltage required by the device body. However, the existing three-phase combined transformer is generally connected to the wire connector by screws, which requires the use of tools and is more troublesome. In addition, the connection between the screw and the wire connector is exposed to the outside, and dust is easily accumulated on the surface. Excessive dust accumulation will lead to poor contact between the wire connector and the three-phase combined transformer.

[0003] For example, a "three-phase combined transformer" disclosed in Chinese patent literature has a publication number of CN216928229U. The three-phase combined transformer includes: a transformer body, a connecting groove is provided inside the upper end of the transformer body, a wrapping block is provided inside the connecting groove, a plug plate is fixedly connected to the bottom of the wrapping block, a connecting head is provided inside the connecting groove, and a wrapping groove is provided inside the wrapping block corresponding to the connecting head; a movable groove, the movable groove is located inside the wrapping block, a rotating plate is provided inside the upper end of the movable groove, the upper end of the rotating plate is fixedly connected to the transmission rod, and the upper end of the transmission rod is fixedly connected to the pull plate.

[0004] Although the above-mentioned scheme can wrap the connection head and the wire connector connection through the setting of the wrapping block, so as to avoid the connection head and the wire connector connection being exposed to the outside and excessive dust accumulation resulting in poor contact, and no separate tools are required to improve the overall connection efficiency, there are still some shortcomings in practical applications. At present, a certain length is reserved when connecting the transformer wiring cables, resulting in some cables being placed in a messy manner on the outside of the three-phase combination transformer after the cables are connected, which is not only unsightly, but also inconvenient to find the corresponding cables during later maintenance and repair, and inconvenient to use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] like Figures 1 to 5 As shown, a three-phase combined transformer comprises: a transformer body 1, a plurality of connection grooves are arranged inside the upper end of the transformer body 1, a wiring connection mechanism 2 is arranged in the connection groove, a winding mechanism 3 is installed at the outer side of the transformer body 1 corresponding to each wiring connection mechanism 2, the winding mechanism 3 is used to store and coil the transformer wiring cables, and the transformer wiring cables are connected to the wiring connection mechanism 2, and the winding mechanism 3 is used to coil and store the transformer wiring cables, so that the transformer wiring cables are neatly arranged, and the problem of the transformer wiring cables being too long and cluttered and difficult to find correctly during maintenance is avoided.

[0027] It should be noted here that the wiring connection mechanism 2 is described in detail in the reference document A three-phase combined transformer <Announcement No. CN216928229U>, and its operating principle and operation steps will not be elaborated here.

[0028] In this embodiment, the wire coiling mechanism 3 includes a shell 31, and two movable plates 32 are symmetrically arranged inside the shell 31. The two movable plates 32 are fixedly connected to the opposite sides with extension plates 33. A plurality of extension plates 33 are arranged along the length direction of the movable plates 32. The extension plates 33 on the two movable plates 32 are staggered. One end of the extension plate 33 is fixedly connected to a connecting column 34. A through slot 311 is transversely opened at the front end of the shell 31 at each connecting column 34. One end of the connecting column 34 passes through the through slot 311 and is connected to a wire member 35. The shell 3 1 is provided with an adjustment component, which is used to drive the two moving plates 32 to move away from each other. When the cable winding mechanism 3 is not in use, the wire members 35 are arranged in two vertical rows. After wiring, the cables are passed between the wire members 35, and then the two moving plates 32 are driven by the adjustment component to move away from each other. The moving plate 32 drives the connecting column 34 and the wire member 35 connected thereto to move synchronously through the extension plate 33, so that the cable is bent and coiled around the multiple wire members 35 in multiple sections, so that the cable can be coiled and stored, and the cable can be neatly arranged.

[0029] In this embodiment, the adjustment assembly includes a bidirectional screw rod 36 rotatably connected to the middle position inside the shell 31 and a driving member 37 installed on one side of the outside of the shell 31. The bidirectional screw rod 36 is arranged horizontally, and the driving member 37 is used to drive the bidirectional screw rod 36 to rotate. Threaded sleeves are fixedly installed at the positions corresponding to the bidirectional screw rods 36 on the two moving plates 32. The threaded sleeves on the two moving plates 32 are respectively threadedly sleeved on the two sides of the bidirectional screw rod 36 in opposite directions. The driving member 37 includes a protective cover 371 fixedly connected to the outside of the shell 31. One end of the bidirectional screw rod 36 A first bevel gear 372 extends into the protective cover 371 and is fixedly connected thereto. One side of the first bevel gear 372 is meshedly connected thereto with a second bevel gear 373. A knob 374 is rotatably connected to the protective cover 371. One end of the knob 374 is fixedly connected to the second bevel gear 373. By rotating the knob 374, the second bevel gear 373 is driven to rotate. The second bevel gear 373 drives the first bevel gear 372 meshed therewith to rotate. The first bevel gear 372 drives the bidirectional screw rod 36 to rotate, thereby making the two movable plates 32 approach or move away from each other through the threaded sleeve.

[0030] In this embodiment, guide rods 38 are fixedly connected to the upper and lower ends of the shell 31. The guide rods 38 are arranged parallel to the bidirectional screw rod 36. A guide sleeve is fixedly installed on the movable plate 32 corresponding to the guide rod 38. The guide sleeve sliding sleeve is sleeved on the outer side of the guide rod 38. During the movement of the movable plate 32, the movable plate 32 slides on the guide rod 38 through the guide sleeve, which plays a role of limiting and guiding the movable plate 32, thereby improving the stability of the movement of the movable plate 32.

[0031] In this embodiment, the wire guide 35 includes a first wire wheel 351 that is rotatably sleeved on the outer side of the connecting column 34. A first wire groove is opened on the outer wall of the first wire wheel 351 along the circumferential direction. When the cable is coiled, the first wire wheel 351 contacts the cable and places the cable in the first wire groove. The cable is driven to move by the first wire wheel 351, which helps the cable to move and coil better.

[0032] In this embodiment, the wire guide 35 also includes a threaded rod 341 fixedly connected to the end of the connecting column 34. The diameter of the threaded rod 341 is smaller than the diameter of the connecting column 34. The threaded rod 341 and the connecting column 34 are integrally formed. A baffle 352 is sleeved on the outer side of the threaded rod 341. A fixing nut 353 is also threadedly connected to the threaded rod 341. The fixing nut 353 is tightly pressed against the baffle 352. The diameter of the baffle 352 is larger than the diameter of the first wire wheel 351. The baffle 352 is fixed to the threaded rod 341 by the fixing nut 353 and blocks the outer side of the first wire wheel 351, thereby blocking and limiting the cable at the first wire wheel 351, preventing the cable from detaching from the first wire wheel 351 and affecting the bending and winding of the cable.

[0033] In this embodiment, a second wire wheel is rotatably connected to the middle position of the upper and lower ends of the front end of the shell 31, and a second wire groove is opened on the outer wall of the second wire wheel along the circumferential direction. The second wire wheel is used to limit the position of the cable entering and exiting the winding mechanism 3.

[0034] In this embodiment, the upper and lower ends of both sides of the shell 31 are fixedly connected with fixing plates 39, and the fixing plates 39 are provided with fixing holes, and bolts are passed through the fixing holes to facilitate the installation and fixing of the winding mechanism 3 on the transformer body 1.

[0035] Implementation plan: When in use, connect the transformer wiring cable to the wiring connection mechanism 2, and then pass the second wire wheel below the cable, between the two vertical rows of wire members 35, and through the two wire wheels above, by turning the knob 374 to drive the second bevel gear 373 to rotate, the second bevel gear 373 drives the first bevel gear 372 engaged therewith to rotate, the first bevel gear 372 drives the bidirectional lead screw 36 to rotate, and the two movable plates 32 are moved away from each other through the threaded sleeve, the movable plate 32 drives the connecting column 34 and the wire member 35 connected thereto to move synchronously through the extension plate 33, the first wire wheel 351 of the wire member 35 contacts the cable, and the cable is placed in the first wire groove, the cable is driven to move by the first wire wheel 351, so that the cable is bent and coiled in multiple sections around the multiple wire members 35, so as to realize the winding and storage of the cable, and to plan the cable neatly, so as to avoid the problem that the transformer wiring cable is too long and cluttered, and it is difficult to find it correctly during maintenance.
