Description

Technical Field

[0001] The utility model relates to the technical field of impregnating machines, and particularly relates to an automatic impregnating machine for transformer production. Background Art

[0002] A transformer is an electrical device that can change the magnitude of alternating voltage. It usually consists of two or more coils and realizes voltage change through the principle of electromagnetic induction. Transformer impregnation refers to a treatment method of completely immersing the coils and iron cores of a transformer in insulating oil (also known as transformer oil). Impregnation can completely wrap the coils and iron cores of the transformer in insulating oil to achieve the purpose of protecting the insulation, ensuring the safe operation of the transformer, and can also dissipate heat well, improve the cooling effect, and reduce the resistance and magnetic resistance of the transformer coils, improve the efficiency of the transformer, reduce the electromagnetic interference inside the transformer, and ensure the stability of the transformer.

[0003] After retrieval, an impregnating machine with the publication number CN218647768U has the main technical points of its technical solution as follows: It includes an impregnating tank. The top surface of the impregnating tank is provided with a liquid storage tank, and two installation slots are provided on the top surface of the impregnating tank; an immersion assembly is arranged on the top surface of the impregnating tank and is used for immersing the transformer. By setting the liquid storage tank, during use, the operator can add varnish into the internal of the liquid storage tank. The operator puts the transformer into the placement hole and then puts the placement box into the internal of the liquid storage tank to realize the impregnation operation of the transformer. Through the vibration of the conveying end of the vibration motor, the vibration is output to the transformer through the placement plate to promote the varnish to enter the gaps inside the transformer, improving the efficiency of the varnish infiltrating into the transformer. When the telescopic shaft of the hydraulic cylinder retracts, it drives the placement box to move downward, so that the transformer enters the internal of the liquid storage tank. When the impregnation of the transformer is completed, the placement box is moved upward by the hydraulic cylinder, which is convenient for the operator to take out the transformer and improves the practicability.

[0004] In this publicly disclosed patent, the impregnating liquid in the impregnating tank will gradually decrease during use. In order to prevent the subsequent impregnation of the transformer from being incomplete, it is necessary for the operator to frequently monitor whether the impregnating liquid in the impregnating tank reaches the standard that needs to be replenished, and the operator manually replenishes the impregnating liquid. Generally speaking, the manual burden is relatively large. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes in detail the above and other technical features and advantages of the present utility model with reference to the accompanying drawings.

[0025] This embodiment provides a technical solution: an automatic impregnating machine for transformer production, as Figures 1-3 shown, includes a support frame 1 and a self-supplementing component 4. The self-supplementing component 4 is arranged below the impregnating liquid tank 3 and is used for automatically replenishing the impregnating liquid into the impregnating box body 2. The impregnating box body 2 is fixed above the support frame 1, the impregnating liquid tank 3 is fixed at the top of the support frame 1, a liquid injection pipe orifice 8 is fixed above the impregnating liquid tank 3, and the impregnating liquid is poured into the impregnating liquid tank 3 through the liquid injection pipe orifice 8 every day for reserved use. A magnetic suction liquid outlet ring opening 5 is provided below the impregnating liquid tank 3;

[0026] As Figures 1-4As shown, the self - replenishing component 4 includes a self - opening part, which automatically detects whether the impregnating liquid inside the impregnating box body 2 is too little and needs to be replenished. When the impregnating liquid needs to be replenished, it opens the magnetic suction liquid outlet ring 5 under the impregnating liquid tank 3, and automatically closes the magnetic suction liquid outlet ring 5 after the impregnating liquid in the impregnating box body 2 is replenished to a certain height. The self - opening part includes a detection floating plate 41, a connecting strip 42, a connecting rod 43, a pulling plate 44, a pushing plate 45, a magnetic suction plugging head 46 and two traction rods 47. A sliding groove 6 is opened on one side of the inner wall of the impregnating box body 2. The detection floating plate 41 slides inside the sliding groove 6 through a traction foot. The detection floating plate 41 is a foam board. One end of the connecting strip 42 is fixed above the detection floating plate 41, and the other end of the connecting strip 42 is fixed to the lower end of the connecting rod 43. The pulling plate 44 is fixed to one end of the connecting rod 43, and the pushing plate 45 is fixed to the outer surface of the connecting rod 43. The distance between the pulling plate 44 and the pushing plate 45 is the same as the length of the sliding groove 6. The length of the sliding groove 6 limits the highest and lowest positions of the detection floating plate 41. When the detection floating plate 41 is at the upper end surface of the sliding groove 6, the impregnating liquid does not need to be replenished. On the contrary, when the detection floating plate 41 is at the lower end surface of the sliding groove 6, the impregnating liquid needs to be replenished. The connecting rod 43 passes through the inside of the magnetic suction liquid outlet ring 5, and the magnetic suction plugging head 46 slides on the outer surface of the connecting rod 43. Both of the two traction rods 47 pass through the inside of the magnetic suction liquid outlet ring 5, and one end of each of the two traction rods 47 is fixed above the magnetic suction plugging head 46.

[0027] As Figures 1-4 shown, the self - replenishing component 4 further includes a liquid replenishing part for transporting the impregnating liquid. The liquid replenishing part includes a connecting shell 48 and an infusion tube 49. The connecting shell 48 is fixed under the impregnating liquid tank 3. The connecting rod 43 passes through the connecting shell 48 and extends into the inside of the connecting shell 48. The connection at the penetration is a sliding connection, and at the penetration connection of the connecting rod 43 and the connecting shell 48, a sealing ring is provided, which can effectively increase the sealing performance at the penetration of the connecting rod 43 and the connecting shell 48. One end of the infusion tube 49 is fixed under the connecting shell 48, and the other end of the infusion tube 49 passes through the impregnating box body 2 and extends into the inside of the impregnating box body 2.

[0028] As Figures 1-4 shown, a transfer component 7 for transferring the transformer is arranged inside the impregnating box body 2. The transfer component 7 includes a carrier frame 71. Two front - and - rear corresponding connecting arms 72 are fixed above the carrier frame 71. Two oil cylinders 73 are arranged under each of the two connecting arms 72. All four oil cylinders 73 are fixed to the outer surface of the impregnating box body 2 through support ring buckles. When the telescopic rods of the four oil cylinders 73 extend simultaneously, the carrier frame 71 is driven to move upward through the two connecting arms 72. The transformer is placed on the carrier frame 71, and then the telescopic rods of the oil cylinders 73 retract, immersing the carrier frame 71 and the transformer together into the impregnating liquid in the impregnating box body 2.

[0029] During use, the impregnating liquid in the impregnating box body 2 will gradually decrease. As the impregnating liquid decreases, the detection floating plate 41 will drop as the liquid level of the impregnating liquid decreases. This drives the connecting strip 42 to move downward. The connecting strip 42 drives the connecting rod 43 to move downward. The connecting rod 43 drives the push plate 45 and the pull plate 44 to move downward together until the pull plate 44 is pulled by the connecting rod 43 to push the magnetic adsorption plug 46 downward. Under the restriction of the traction rod 47, the magnetic adsorption plug 46 slides vertically downward until the magnetic adsorption plug 46 is pushed out of the magnetic adsorption liquid outlet ring 5. The impregnating liquid stored in the impregnating liquid tank 3 will then pass through the magnetic adsorption liquid outlet ring 5 into the connection shell 48 and flow into the impregnating box body 2 through the infusion tube 49. As the impregnating liquid is replenished, the liquid level of the impregnating liquid in the impregnating box body 2 gradually rises. Therefore, the detection floating plate 41 rises accordingly, and thus the connecting strip 42 drives the connecting rod 43 to move upward. The connecting rod 43 will push the magnetic adsorption plug 46 into the magnetic adsorption liquid outlet ring 5 through the push plate 45 to block the outflow of the impregnating liquid.

[0030] The above is only a preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
