Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, and particularly relates to a dipping equipment for dry-type three-phase combined transformers. Background Art

[0002] A combined transformer is actually a combination of a voltage transformer and a current transformer. It can be a combination of one voltage transformer and one current transformer for measuring single-phase power; it can be a combination of two voltage transformers and two current transformers for measuring three-phase power by the two-wattmeter method in a three-phase three-wire system; it can also be a combination of three voltage transformers and three current transformers for three-phase power measurement. When connected to a transformer, the voltage terminals of the combined transformer are connected in parallel with the output of the transformer, and the transformer current line passes through the combined transformer. To avoid electric shock when lifting the transformer, it is necessary to apply an insulating paint coating to the transformer element.

[0003] Currently, dipping equipment is used to apply an insulating paint coating to the outer surface of the transformer element. The existing publicly disclosed patent: A dipping equipment for a transformer CN202321357588.7 installs an air outlet pipe at the bottom of the drying box, and through the introduction component, the paint in the drying box can be introduced back into the dipping box again, so as to recycle and reuse the paint, saving resources. However, the paint will precipitate after being placed for a certain period of time, and there is no suitable mechanism in this comparative example to mix the paint evenly, which will affect the evenness of the insulating paint coating on the outer surface of the transformer element, and further affect the dipping effect of the transformer element.

[0068] Among them, the front and rear side surfaces of the sealing plate 9 are slidably connected to the front and rear inner walls of the housing 2;

[0069] Among them, the motor bracket 21 is fixedly connected to the right side surface of the housing 2.

[0070] Furthermore, the second motor 22 is fixedly connected to the upper surface of the motor bracket 21;

[0071] Among them, the positioning groove 10 is provided on the lower surface of the sealing plate 9;

[0072] Among them, a rack is fixedly connected to the top wall of the positioning groove 10;

[0073] Among them, the rotating rod 23 is fixedly connected to the rotating output shaft of the second motor 22;

[0074] Among them, the gear 24 is fixedly connected to one end of the rotating rod 23 away from the second motor 22;

[0075] Among them, the gear 24 is meshed and connected with the rack through the positioning groove 10.

[0076] Furthermore, the positioning shaft 11 is rotatably connected to the lower surface of the housing 2, and the upper end of the positioning shaft 11 rotatably penetrates into the housing 2;

[0077] Among them, a seal is provided between the positioning shaft 11 and the housing 2;

[0079] Among them, the sliding groove 14 is opened on the lower surface of the sliding block 13, and the sliding groove 14 extends upward out of the upper surface of the sliding block 13.

[0080] Furthermore, the first motor 17 is fixedly connected to the mounting bracket 1;

[0081] Among them, the second fixing rod 18 is fixedly connected to the rotating output shaft of the first motor 17;

[0082] Among them, the first fixing rod 16 is fixedly connected to the outer surface of the second fixing rod 18;

[0083] Among them, the connecting block 15 is fixedly connected to one end of the first fixing rod 16 away from the second fixing rod 18;

[0084] Among them, the upper side of the connecting block 15 extends into the sliding groove 14, and the connecting block 15 is slidably connected to the sliding groove 14;

[0085] Among them, a plurality of mixing rods 12 are fixedly connected to the outer surface of the positioning shaft 11 located inside the housing 2.

[0086] Furthermore, during use, the inside of the housing 2 is filled with paint, and the height of the paint should be lower than the height of the connecting groove 8. Then, the transformer element to be dipped in paint is placed on the permeable net 20, and then the electric push rod 4 is started to drive the permeable net 20 and the connecting frame 19 to move downward. During the movement of the permeable net 20 and the connecting frame 19, the transformer element is immersed in the paint, thereby performing the paint dipping work on the transformer element;

[0087] As described above, after the impregnation is completed, the electric push rod 4 is started to drive the permeable net 20, the connecting frame 19 and the mutual inductor element to move upward, so that the permeable net 20, the connecting frame 19 and the mutual inductor element are located above the sealing plate 9. At this time, the permeable net 20, the connecting frame 19 and the mutual inductor element are separated from the paint liquid. After ten seconds (which can be adjusted according to the viscosity of the paint, etc.), the second motor 22 is started. The second motor 22 starts to drive the rotating rod 23 and the gear 24 to rotate, and then synchronously drives the rack to move left and right. When driving the sealing plate 9 to move left, the sealing plate 9 enters the housing 2. When the left side surface of the sealing plate 9 moves left to contact the left inner wall of the housing 2, the power supply of the second motor 22 is disconnected. Then, the sealing plate 9 seals the housing 2 into two spaces. At this time, the fan 7 can be started to air-dry the mutual inductor element, thereby accelerating the drying of the mutual inductor element and improving the impregnation efficiency of the mutual inductor element;

[0088] As described above, the lower side of the housing 2 is sealed by the sealing plate 9 to prevent the paint from being over-dried during the drying process of the mutual inductor element, thereby ensuring the impregnation effect and quality of the mutual inductor element, and further ensuring the practicability of the impregnation equipment.

[0089] As described above, when the first motor 17 is started, the first motor 17 starts to drive the second fixed rod 18, the first fixed rod 16 and the connecting block 15 to rotate around the sliding groove 14. During the rotation of the connecting block 15, the sliding block 13 is driven to rotate reciprocally around the positioning shaft 11, and then the mixing rod 12 is synchronously driven to rotate reciprocally, thereby mixing the paint in the housing 2 evenly, avoiding the phenomenon of uneven paint mixing, avoiding paint precipitation, ensuring the uniformity of the impregnation of the mutual inductor element, and further ensuring the impregnation effect and quality of the mutual inductor element.

[0090] Furthermore, in this solution, the first motor 17 is a motor with self-locking performance, such as a conical rotor motor. The rotating output shaft of this type of motor is self-locked and will not rotate after power-off.

[0091] Working principle: When the device is in use, paint is injected into the housing 2, and the height of the paint should be lower than the height of the connecting groove 8. Then, the mutual inductor element to be impregnated is placed on the permeable net 20. Then, the electric push rod 4 is started to drive the permeable net 20 and the connecting frame 19 to move downward. During the movement of the permeable net 20 and the connecting frame 19, the mutual inductor element is immersed in the paint, thereby performing the impregnation work on the mutual inductor element;

[0092] As described above, after the impregnation is completed, the electric push rod 4 is started to drive the permeable net 20, the connecting frame 19 and the mutual inductor element to move upward, so that the permeable net 20, the connecting frame 19 and the mutual inductor element are located above the sealing plate 9. At this time, the permeable net 20, the connecting frame 19 and the mutual inductor element are separated from the paint liquid. After ten seconds (which can be adjusted according to the viscosity of the paint, etc.), the second motor 22 is started. The second motor 22 starts to drive the rotating rod 23 and the gear 24 to rotate, and then synchronously drives the rack to move left and right. When driving the sealing plate 9 to move to the left, the sealing plate 9 enters the housing 2. When the left surface of the sealing plate 9 moves to the left and contacts the left inner wall of the housing 2, the power supply of the second motor 22 is disconnected. Then, the sealing plate 9 seals the housing 2 into two spaces. At this time, the fan 7 can be started to air-dry the mutual inductor element, thereby accelerating the drying of the mutual inductor element and improving the impregnation efficiency of the mutual inductor element;

[0093] As described above, the lower side of the housing 2 is sealed by the sealing plate 9 to prevent the paint from being over-dried during the drying process of the mutual inductor element, thereby ensuring the impregnation effect and quality of the mutual inductor element, and thus ensuring the practicability of the impregnation equipment.

[0094] As described above, when the first motor 17 is started, the first motor 17 starts to drive the second fixed rod 18, the first fixed rod 16 and the connecting block 15 to rotate around the sliding groove 14. During the rotation of the connecting block 15, the sliding block 13 is driven to rotate reciprocally around the positioning shaft 11, and then the mixing rod 12 is synchronously driven to rotate reciprocally, thereby mixing the paint in the housing 2 evenly, avoiding the phenomenon of uneven paint mixing and preventing the paint from settling, thereby ensuring the uniformity of the impregnation of the mutual inductor element, and also ensuring the impregnation effect and quality of the mutual inductor element.

[0095] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
