Description

Technical Field

[0001] The utility model relates to the technical field of oil-immersed transformer installation, and specifically to an oil-immersed transformer assembly bracket. Background Technique

[0002] During operation, the oil-immersed transformer will vibrate and shake. This is because there are magnetic and electric fields inside the transformer, and these forces may cause the transformer to vibrate. In addition, the transformer oil will also generate a certain degree of shaking during operation. If the installation position is stable, the fixing is good, and the accessories are installed correctly, these vibrations and shakes should be acceptable. When the vibrations and shakes are relatively large, the friction between the bolts may decrease, resulting in bolt loosening, which will cause the oil-immersed transformer to become unstable. Therefore, we propose an oil-immersed transformer assembly bracket to ensure the stability of the installation position and avoid instability. Content of the Utility Model

[0003] The purpose of the utility model is to provide an oil-immersed transformer assembly bracket to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An oil-immersed transformer assembly bracket includes columns and a fixing structure. The number of the columns is two, and they are buried symmetrically horizontally. The outer walls of the columns are symmetrically provided with support brackets for the tray. The side walls of the support brackets for the tray are fastened by bolts. The lower surface of the support brackets for the tray is provided with semi-circular hoops. The inner wall of the semi-circular hoops is fastened to the outer wall of the columns. The upper surface of the support brackets for the tray is symmetrically provided with a fixing structure. The upper surface of the fixing structure is fixedly connected with an oil-immersed transformer.

[0005] Preferably, the fixing structure includes concave plates. The number of the concave plates is two, and they are symmetrically arranged horizontally. The upper surface of the concave plates is fixedly connected with the lower surface of the oil-immersed transformer. The inner side walls of the concave plates are buckled with the outer walls of the support brackets for the tray. The lower surface of the concave plates is fixedly connected with screw rods. Rubber pads are sleeved on the outer walls of the screw rods. The lower surfaces of the rubber pads are attached to the upper surfaces of the support brackets for the tray. A top plate is provided on the lower surface of the tray. The center of the top plate is in clearance fit with the screw rod. The lower surface of the top plate is fixedly connected with a threaded sleeve. The inner cavity of the threaded sleeve is threadedly connected with the outer wall of the screw rod. The bottom end of the screw rod is buckled with a square groove block. Symmetrically fixed connection tensile springs are arranged on the upper surface of the square groove block. The other ends of the tensile springs are fixedly connected with the lower surface of the top plate.

[0006] Preferably, the bottom end of the screw rod is provided with a square protrusion, and the diameter of the square protrusion is smaller than that of the screw rod.

[0007] Preferably, the number of the screws is four, and they are symmetrically arranged on one side.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: When assembling an oil-immersed transformer, the concave plate snap-on installation and the screws with square protrusions at the bottom are adopted. During the fastening process, the top plate fits with the bottom of the support bracket of the pallet, and at the same time, the threaded sleeve is thread-fastened with the screw. The top plate and the concave plate form symmetric clamping and fixing. At the same time, the square protrusion at the bottom is smaller than the diameter of the screw, which does not affect the normal penetration of the screw through the threaded sleeve. The square groove block is buckled with the protrusion at the bottom of the screw. Through the pulling of the tension spring, the screw can be limited when there is shaking and vibration, so that the screw can be kept stable and the phenomenon of loosening during the vibration or shaking of the oil-immersed transformer can be avoided. This helps to improve the stability and reliability of the transformer. Since the stability of the fixing parts is enhanced, the phenomenon of instability caused by loosening can be reduced, the stability of the oil-immersed transformer is improved, the potential safety hazard is reduced, and the production safety is improved.

[0017] Please refer to Figures 1-6 , the present utility model provides an oil-immersed transformer assembly bracket, which includes columns 1 and a fixing structure 4. The number of columns 1 is two, and they are buried symmetrically horizontally. The outer walls of the columns 1 are symmetrically provided with support brackets 2 for the tray. The side walls of the support brackets 2 for the tray are fastened by bolts. The lower surface of the support brackets 2 for the tray is provided with a semi-circular hoop 3. The inner ring wall of the semi-circular hoop 3 is fastened to the outer wall of the column 1. The upper surface of the support brackets 2 for the tray is symmetrically provided with a fixing structure 4. The upper surface of the fixing structure 4 is fixedly connected with an oil-immersed transformer 5.

[0018] When assembling the oil-immersed transformer 5, first ensure that the equipment and the working site are clean, tidy, and meet safety standards. Horizontally bury the columns 1 symmetrically at the installation site. The columns 1 serve as the fixing points of the transformer. Then install the semi-circular hoop 3 on the outer wall of the column 1. Symmetrically arrange the support brackets 2 for the tray on the top of the semi-circular hoop 3. The two sides of the support brackets 2 for the tray are butted and fixed by bolts, clamped on the outer wall of the column 1, and at the same time, there is a semi-circular hoop 3 at the bottom for lifting, realizing double fixation. Then move the oil-immersed transformer 5 by hoisting. The oil-immersed transformer 5 is connected and fixed to the support brackets 2 for the tray through the fixing structure 4. The shape of the concave plate 41 is buckled with the support brackets 2 for the tray. While buckling, the screw 43 will penetrate through the support brackets 2 for the tray. A rubber pad 42 is arranged between the concave plate 41 and the support brackets 2 for the tray for shock absorption. At the same time, the top plate 45 is fitted with the screw 43.

While fixing, the top square groove block 47 is pulled by the tension spring 46, and the bottom square groove block 47 is fitted with the bottom of the screw 43. The bottom of the screw 43 is square-shaped. Since the square protruding part is smaller than the diameter of the screw 43, it will not affect the socket connection between the screw 43 and the threaded sleeve 44. The square groove block 47 is buckled with the bottom of the screw 43. When the oil-immersed transformer 5 vibrates and shakes, the screw 43 is kept stable by the pulling of the tension spring 46, avoiding loosening. When the overall assembly is completed, a comprehensive inspection and test should be carried out on the transformer to ensure the quality and safety of the transformer.

[0019] The fixed structure 4 includes concave plates 41. The number of the concave plates 41 is two, and they are symmetrically arranged horizontally.

A rubber pad 42 is sleeved on the outer wall of the screw 43. The lower surface of the rubber pad 42 is attached to the upper surface of the support plate bracket 2. A top plate 45 is arranged on the lower surface of the support plate 2. The center of the top plate 45 is in clearance fit with the screw 43. A threaded sleeve 44 is fixedly connected to the lower surface of the top plate 45. The inner cavity of the threaded sleeve 44 is threadedly connected to the outer wall of the screw 43. A square groove block 47 is buckled at the bottom end of the screw 43. Tensile springs 46 are symmetrically and fixedly connected to the upper surface of the square groove block 47. The other ends of the tensile springs 46 are fixedly connected to the lower surface of the top plate 45.
