Embodiment Construction
[0015] A special tool for making a large cover sealing rubber pad of a power transformer, comprising a pair of splints, one side of the splint has a groove structure and both sides of the groove are connected; the sides of the two splints with grooves are relatively fastened together, There are screw holes corresponding to each other on each of the splints, and a set screw is provided in the screw holes to fasten the two splints together; There is a top wire inside; the two splints are buckled and placed horizontally, and there are fixed tangent grooves on the two splints after the buckle; And it is at a certain angle with the edge of the groove, and the fixed cut surface groove does not run through the entire splint. Such as figure 1 , 2 As shown, the shape of the splint is a rectangular structure, the grooves are arranged along the long center line of the splint, the fixed cut surface groove extends from one long side of the splint to the inside of the splint, and forms an...

The invention relates to a transformer overhaul technical process suitable for actual work of a power transformer overhaul site, and particularly relates to a special tool and a method for manufacturing a power transformer big cover sealing rubber gasket. The special tool and the 45-degree section angle butt joint method for manufacturing the power transformer big cover sealing rubber gasket are applied, so that 100% coaxial parallel, longitudinal and transverse acting force of a whole rubber rope can be kept uniform, and the situation that the sealing effect is affected due to the fact that the section angles are different and uneven when the rubber gasket is manufactured and the compression amount cannot be used uniformly is avoided. Fixed section grooves formed in two clamping plates together can ensure that the sections of the rubber rope are neat.
Description
technical field [0001] The invention relates to a transformer overhauling technology, which is suitable for the actual work on the overhaul site of a power transformer, and specifically relates to a special tool and method for making a large cover sealing rubber pad of a power transformer. Background technique [0002] In the current on-site work of overhauling transformers, most of them still use artificially made transformer cover sealing rubber pads. Because the sealing rubber pad is an oil-resistant rubber product, at least three people are required to complete this work each time. The process requires that the butt joint cut surface be flat and the cut surface angle is 45 degrees. Manual operation directly presses and cuts the cut surface often resulting in uneven cut surfaces. After the butt joint, the pasting surface is not flat, nor is it parallel to the "coaxial" enough, and there is still a certain error. Due to the different angles of the cutting surface, unevenne...
