Technical Field

[0001] The invention relates to a transformer oil tank strength test lower body support structure and method thereof, belonging to the technical field of transformer power transmission and transformation. Background Art

[0002] After the transformer body is assembled, pads are usually used between the body clamp support plate and the tank cover to prevent the tank cover from deforming during the tank strength test. In the past, laminated wood pads were directly used to support the transformer body. This structure has high rigidity, and the rebound force after the tank strength test may cause quality problems for the tank cover. Summary of the invention

[0003] The purpose of the present invention is to provide a transformer oil tank strength test body support structure and method thereof, leaving a suitable size at the bottom of the laminated wood pad, adding a rubber pad and a plurality of adjustment pads, which can ensure reliable support between the body support plate and the box cover, can play a regulating role, and can also play a buffering role, is suitable for various transformers, ensures the safety of the transformer, and solves the problems existing in the background technology.

[0004] The technical solution of the present invention is: A transformer oil tank strength test lower body support structure comprises a laminated wood pad, a bakelite screw, a rubber pad, an adjusting pad, a box cover and a body support plate. The laminated wood pad, the rubber pad and a plurality of adjusting pads of different thicknesses are arranged in sequence from top to bottom between the box cover and the body support plate. The laminated wood pad, the rubber pad and the plurality of adjusting pads of different thicknesses are connected to the body support plate through the bakelite screw.

[0005] The thickness of the adjusting pad decreases from thick to thin from top to bottom.

[0006] There are three adjusting pads.

[0007] The thicknesses of the three adjusting pads are 5 mm, 2 mm and 1 mm respectively.

[0008] A transformer tank strength test lower body support method is performed according to the following steps: Step 1: Place a laminated wood block between the box cover and the body support plate, and leave a certain space between the laminated wood block and the body support plate; Step 2: Place a rubber pad and several adjustment pads of different thicknesses in the space between the laminated wood pad and the body support plate from top to bottom; Step 3: Use bakelite screws to connect the laminated wood pads, rubber pads and several adjustment pads of different thicknesses to the body support plate.

[0009] There are three adjusting pads, and the thickness of the three adjusting pads decreases from thick to thin from top to bottom.

[0010] The thicknesses of the three adjusting pads are 5 mm, 2 mm and 1 mm respectively.

[0011] The beneficial effects of the present invention are: reliable support between the body support plate and the box cover can be ensured, and both a regulating effect and a buffering effect can be played, and the present invention is suitable for various transformers to ensure the safety of the transformers. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the overall structure of the present invention; Figure 2 It is a partial enlarged view of the present invention; In the figure: laminated wood pad 1, bakelite screw 2, rubber pad 3, adjustment pad 4, box cover 7, support pad 8, body support plate 9. DETAILED DESCRIPTION

[0013] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0014] Refer to the attached Figure 1 , 2 A transformer oil tank strength test lower body support structure comprises a laminated wood pad 1, a bakelite screw 2, a rubber pad 3, an adjusting pad, a box cover 7 and a body support plate 9. The laminated wood pad 1, the rubber pad 3 and a plurality of adjusting pads of different thicknesses are arranged between the box cover 7 and the body support plate 9 from top to bottom. The laminated wood pad 1, the rubber pad 3 and a plurality of adjusting pads of different thicknesses are connected to the body support plate 9 through a bakelite screw 2.

[0015] In this example, refer to the attached Figure 1 , 2 The transformer tank strength test lower body support structure includes a laminated wood pad 1, a bakelite screw 2, a rubber pad 3, three adjustment pads, a tank cover 7 and a body support plate 9, wherein the thickness of the three adjustment pads are 5 mm, 2 mm and 1 mm respectively, and the following steps are performed: Step 1: Place a laminated wood pad 1 between the box cover 7 and the body support plate 9, and leave a certain space between the laminated wood pad 1 and the body support plate 9; Step 2: Place the rubber pad 3 and the 5mm adjustment pad, the 2mm adjustment pad and the 1mm adjustment pad in the space between the laminated wood pad 1 and the body support plate 9 from top to bottom; Step 3: Use bakelite screw 2 to connect laminated wood pad 1, rubber pad 3, 5mm adjustment pad, 2mm adjustment pad and 1mm adjustment pad with body support plate 9.

[0016] Adding rubber pads 3 and 5mm adjusting pads, 2mm adjusting pads and 1mm adjusting pads can ensure reliable support between the body support plate and the box cover, which can play both an adjusting role and a buffering role.
