[0001] The utility model relates to the technical field of transformers, in particular to a transformer insulating oil adder. Background Art

[0002] Insulating oil plays a key role in insulation, heat dissipation and lubrication in transformers. When adding insulating oil, it is necessary to select appropriate insulating oil according to the transformer design and operating environment, and ensure that the added insulating oil is of the same grade and type as the original transformer to ensure its electrical, chemical and thermal stability compatibility. When adding insulating oil, staff usually distinguish different types of insulating oil, and then add it manually with the help of tools such as pipes or funnels, which is inconvenient to operate.

[0003] In order to solve the above problems, we propose a transformer insulating oil adder which can store different types of insulating oil for adding. Utility Model Content

The moving frame is fixedly connected to the limiting disk, the limiting disk is rotatably connected to the rotating frame, the rotating frame is fixedly connected to the arc plates equidistantly distributed in the circumferential direction, the rotating frame is fixedly connected to the liquid storage barrels equidistantly distributed in the circumferential direction, the bottom ends of the liquid storage barrels are connected to the lower oil pipe, the moving frame is fixedly connected to the limiting shell, the front part of the limiting shell is provided with a connecting pipe slidably connected between the limiting grooves, the connecting pipe is spliced ​​with the adjacent lower oil pipe, the moving frame is provided with a lifting assembly for controlling the lifting and lowering of the lower oil pipe, and the moving frame is provided with a rotating assembly for controlling the rotation of the rotating frame.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0018] Embodiment 1: A transformer insulating oil adder, such as Figure 1-Figure 4As shown, it includes a mobile frame 1, a limit plate 2, a rotating frame 3, an arc plate 4, a transparent plate 5, a liquid storage barrel 6, an oil filling cover 7, a lower oil pipe 8, a connecting pipe 9, a limit shell 10, a lifting assembly and a rotating assembly. The mobile frame 1 is fixedly connected to the limit plate 2 at the center position, the limit plate 2 is rotatably connected to the rotating frame 3, six arc plates 4 equidistantly distributed in the circumferential direction are fixedly connected to the rotating frame 3, the middle of the arc plate 4 is fixedly connected to the transparent plate 5, and six liquid storage barrels equidistantly distributed in the circumferential direction are fixedly connected inside the rotating frame 3 6, an oil filling cap 7 is screwed on the upper side of the liquid storage barrel 6, and a lower oil pipe 8 is connected to the lower side of the liquid storage barrel 6. An electronic valve is installed on the lower oil pipe 8. A limit shell 10 is fixedly connected to the lower part of the movable frame 1, and a left-right symmetrical limit groove 11 is opened in the front part of the limit shell 10. A connecting pipe 9 is slidably connected between the left and right limit grooves 11. The connecting pipe 9 is spliced ​​with the adjacent lower oil pipe 8. A lifting component for controlling the lifting and lowering of the lower oil pipe 8 is provided on the movable frame 1, and a rotating component for controlling the rotation of the rotating frame 3 is provided on the movable frame 1.

[0019] When using the device, the staff opens the oil filling cover 7, and then adds different types of insulating oil into the six liquid storage barrels 6 respectively. When it is necessary to add insulating oil to the transformer, the staff connects the transformer and the connecting pipe 9 through a pipeline, and then opens the electronic valve. The insulating oil in the liquid storage barrel 6 can be added to the transformer through the lower oil pipe 8 and the connecting pipe 9. When it is necessary to replace the insulating oil of a different type, the staff controls the connecting pipe 9 to slide downward and disengage from the lower oil pipe 8 through the lifting component, and then drives the rotating frame 3 to rotate through the rotating component, thereby driving the liquid storage barrel 6 to rotate. When the liquid storage barrel 6 of the appropriate type rotates to the front, the staff controls the connecting pipe 9 to slide upward and splice with the lower oil pipe 8 through the lifting component, thereby achieving the purpose of changing the oil number. When adding insulating oil, the transparent plate 5 can facilitate the staff to view the remaining amount in the liquid storage barrel 6.

[0020] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 and Figure 4 As shown, the lifting assembly includes a connecting frame 12 and an electric push rod 13. The connecting frame 12 is fixedly connected to the middle of the connecting pipe 9, and the electric push rod 13 is fixedly connected to the front of the moving frame 1. The telescopic end of the electric push rod 13 is connected to the connecting frame 12.

[0021] When using this device, the staff controls the extension and contraction of the electric push rod 13 to drive the connecting frame 12 to move up and down. The up and down movement of the connecting frame 12 drives the connecting pipe 9 to slide up and down, thereby controlling the docking state of the connecting pipe 9 and the lower oil pipe 8, so that the staff can better use different types of insulating oil.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the rotating assembly includes a protective shell 14, a driving motor 15, a worm 16 and a worm wheel 17. The protective shell 14 is fixedly connected to the mobile frame 1, the driving motor 15 is fixedly connected to the left part of the mobile frame 1, the worm 16 is fixedly connected to the output shaft of the driving motor 15, and the worm wheel 17 is fixedly connected to the lower part of the rotating frame 3, and the worm wheel 17 is meshed with the worm 16.

[0023] When the device is used, the driving motor 15 drives the worm 16 to rotate, the rotation of the worm 16 drives the worm wheel 17 to rotate, the rotation of the worm wheel 17 drives the rotating frame 3 to rotate, and then drives the liquid storage barrel 6 to rotate to switch different types of insulating oil. At the same time, under the action of the self-locking function of the worm 16 and the worm wheel 17, it can also prevent the rotating frame 3 from rotating abnormally during the process of adding insulating oil.

[0024] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
