[0004] During production, the casing mounting flange must be processed as a whole, and the thickness of the entire flange is the same. Because it is necessary to drill blind holes for the casing mounting flange, it is required that the casing mounting flange must have a certain thickness, so it is comparable to the general flange. In order to reduce the use of steel and ensure the fixing strength at the same time, technicians in the field can only reduce the thickness and diameter of the casing installation flange as much as possible for many years, but this method does not have a very obvious saving on steel Effect

Abstract
The invention discloses a sleeve mounting flange for a transformer. The sleeve mounting flange is characterized by comprising an annular upper plate and an annular lower plate, thickness of the upper plate is larger than that of the lower plate, and external diameter of the upper plate is smaller than that of the lower plate and larger than internal diameter of the lower plate; centers of the welded upper and the lower plates are in a same perpendicular line; connecting holes are formed in the upper plate and of blind holes. Compared with the common sleeve mounting flange, simple and reasonable improvement on structure is performed, at the premise of high performance and quality of the sleeve mounting flange and guaranteed fixing strength of a sleeve, steel products are remarkably saved, production cost is lowered, and economic benefits are improved.
Description
technical field [0001] The invention relates to the technical field of flanges for installing transformer bushings in the electric power industry, in particular to a flange for installing transformer bushings. Background technique [0002] The transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer winding must pass through the insulating bushing to insulate the lead wires and between the lead wires and the transformer shell, and at the same time play the role of fixing the lead wires. The power transformer bushings of 110kV level and above are generally fixed on the bushing riser of the transformer box cover or box wall, and the upper part of the riser is provided with a bushing installation flange for bushing installation. [0003] In the prior art, the casing mounting flange has two structures: one is that the casing mounting flange 1 is directly welded on the casing mounting riser 2, and the upper part of the casin...
