[0049] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0050] Example

[0051] like Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 As shown, the high-precision instrument transformer winding insulation treatment device includes a bearing component 1 and a fixing component 2.

[0052] The support assembly 1 is used to support the current transformer. The support assembly 1 includes a base 13, a barrel 12 is provided on the base 13, a DC motor 5 is provided in the middle of the base 13, and the output end of the DC motor 5 passes through the base 13 to the barrel 12. The top of the barrel 12 is provided with an opening, and the top of the barrel 12 is provided with a barrel cover 11 that can fully close the top opening of the barrel 12. An atomizing head 4 and a curing lamp 3 are provided on the inner side wall of the barrel 12. An annular air duct 14 is provided on the base 13 and communicates with the inside of the barrel 12.

[0053] The barrel body 12 and the barrel lid 11 are hinged and sealed, which is a conventional technology. The barrel body 12 and the barrel lid 11 are provided with a fixing buckle on the side away from the hinge, which is also a conventional technology.

[0054] The base 13 has an embedding groove 131 on its top, and the barrel 12 is embedded in the embedding groove 131. The embedding setting can stably seal the bottom air duct, and sealant can be added to the embedding groove 131 to prevent damage to the air duct structure from the connection.

[0055] The annular air duct 14 is located on the bottom surface of the base 13, such as... Figure 3 As shown, the annular air duct 14 is an annular open slot that connects at least two arc-shaped air guide plates 15, or all air guide plates can be connected. Depending on the different functions, all arc-shaped air guide plates 15 can be set as hot air outlets, or hot air outlets and exhaust vents can be set up alternately.

[0056] The bottom of the barrel 12 is provided with an arc-shaped air guide plate 15 for spiral air outlet; the arc-shaped air guide plate 15 can form a spiral air outlet, thereby further distributing hot air to each part, making the air outlet more stable and uniform.

[0057] In the embodiment, as shown in the figure, several arc-shaped air guide plates 15 are arranged in a circular array along the bottom of the barrel 12, and all the arc-shaped air guide plates 15 are arranged concentrically with the same center.

[0058] The arc-shaped air guide plate 15 is a fan-shaped tubular air outlet, and the arc-shaped air guide plate 15 is integrally formed with the barrel body 12. The fan-shaped tubular shape can match the air outlet sequence with the annular air duct 14, thereby achieving a good air outlet effect and spiral wind effect.

[0059] The curved air guide plate 15 also contains an air guide vane 151 that is inclined relative to the air outlet direction. The spiral wind effect is mainly achieved by the curved air guide plate 15 to guide the hot air.

[0060] In this embodiment, in order to ensure the sealing effect, an airtight valve is installed on the connecting pipe between the annular air duct 14 and the hot air blower, which is controlled by the PLC system described below.

[0061] In this embodiment, both the atomizing head 4 and the curing lamp 3 are conventional methods. In actual operation, spraying-curing is the standard process. In this solution, the vacuum state during spraying can greatly reduce the interference of various environments. The annular air duct 14 can not only supply air but also exhaust air. The specific PLC control process is described here and will not be elaborated.

[0062] In this embodiment, auxiliary parts such as compressors and air heating elements are not described in detail. They are not related to this technical solution or have no improvement points, and are conventional devices used in this field, so they will not be described in detail either.

[0063] In this embodiment, the structure of the base 13 will not be described in detail, as it is a conventional and suitable setting. As shown in the figure, air passage holes are provided corresponding to the arc-shaped air guide plate 15.

[0064] In this scheme, the DC motor 5 is a common plug-in DC motor 5, which is controlled and driven by PLC in this embodiment, but can also be driven manually.

[0065] Fixing component 2 is used to fix the current transformer and is located at the end of the output terminal of the DC motor 5.

[0066] The fixing assembly 2 includes a flange 21 disposed at the output end of the DC motor 5. A Y-axis guide rail 22 is slidably disposed on the side of the flange 21 near the opening of the barrel 12. A lifting column 23 is slidably disposed on the side of the Y-axis guide rail 22 near the opening of the barrel 12. The lifting column 23 is disposed perpendicular to the Y-axis guide rail 22. At least two telescopic rods 24 are disposed at the end of the lifting column 23 away from the Y-axis guide rail 22. A flexible fixing rod 26 that abuts against the current transformer is disposed at the end of the telescopic rods 24 away from the lifting column 23. The flange 21 is designed to prevent atomization near the motor output end. The flange 21, Y-axis guide rail 22, and lifting column 23 are designed to effectively adjust the position of the winding to prevent jamming or eccentric rotation due to inability to adjust the position.

[0067] A spring 25 is fitted onto the telescopic rod 24. The spring 25 ensures that the telescopic rod 24 is always in an expanded state and cannot effectively clamp the winding.

[0068] An X-sliding groove 211 is provided on the side of the flange 21 near the opening of the barrel 12, and a Y-axis slider embedded in the X-sliding groove 211 is provided on the bottom surface of the Y-axis guide rail 22. The X-sliding groove 211 enables the Y-axis guide rail 22 to slide, thereby forming a three-dimensional movement, which can further prevent eccentric rotation.

[0069] The top surface of the Y-axis slide rail is provided with a Y-axis sliding groove, and the bottom end of the telescopic rod 24 is slidably disposed within the Y-axis sliding groove. The Y-axis sliding groove assists the telescopic rod 24 in sliding along the direction of the Y-axis sliding groove.

[0070] In this solution, the three-dimensional fixed slide rail assembly can directly fix the winding. However, in order to more conveniently adjust the eccentric rotation problem, a micro motor can also be set in this solution, and the slide rod in the X slide groove 211 can be replaced with a screw, and the slide rod in the Y slide groove 221 can be replaced with a screw, so as to more conveniently adjust the eccentric movement. The setting of the lifting column 23 can be adapted to the longer winding. The lifting column 23 can be driven by a cylinder. In the hands of those skilled in the art, the setting of pneumatic components and micro motors is relatively conventional, and only adaptive adjustments are needed. There is no need to describe the working principle and working effect.

[0071] Working principle: The winding can be completely fixed inside the barrel 12 by the setting of the fixing component 2. The barrel 12 can isolate external impurities. The DC motor 5 rotates evenly. The atomizing head 4 can effectively atomize and spray the insulating material onto the winding. The curing lamp 3 cures evenly and slowly. The annular air duct 14 assists the curing lamp 3 to further cure.

[0072] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0073] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
