Abstract
Изобретение относится к электротехнике и может быть использовано в трансформаторостроении. Технический результат состоит в снижении потерь электротехнической стали, в частности, при изготовлении внутриконтурных вертикальных стержней трансформаторов, а также веса и габарита магнитопровода в целом. Шихтованный магнитопровод трансформатора содержит два крайних вертикальных стержня, не менее одного внутриконтурного вертикального стержня и двух горизонтальных верхнего и нижнего ярем 3, собранных из пакетов пластин. Пластины крайних стержней и ярем имеют трапециевидную форму со скосами в крайних углах β, равных 45°. Горизонтальные ярма со стороны внутриконтурных вертикальных стержней выполнены с вырубленными V-образными углами α на глубину, меньшую, чем ширина ярем, а пластины внутриконтурных вертикальных стержней 2 ограничены соответствующими им V-образными углами, в которых вершины пластин 5 внутриконтурных вертикальных стержней отсечены. Изготовление шихтованного магнитопровода, включающее штамповку пластин крайних, внутриконтурных вертикальных стержней и горизонтальных ярем из полос электротехнической стали, с получением предварительно заданных форм, детальную сортировку и шихтовку пластин в замкнутый магнитопровод, с послойным смещением их в пакетах в зоне стыковки пластин вертикальных стержней и горизонтальных ярем, штамповку пластин внутриконтурных вертикальных стержней, выполняют при помощи инструмента, рабочие деформирующие части которого образуют с двух концов V-образные углы с отсеченными вершинамиThe invention relates to electrical engineering and can be used in transformer. The technical result consists in reducing the loss of electrical steel, in particular, in the manufacture of contour vertical rods of transformers, as well as the weight and size of the magnetic circuit as a whole. The transformed magnetic core contains two extreme vertical rods, at least one in-loop vertical rod and two horizontal upper and lower yoke 3, assembled from plate packs. The plates of the extreme rods and yoke have a trapezoidal shape with bevels in the extreme corners β, equal to 45 °. The horizontal yokes on the side of the contour vertical rods are made with cut V-shaped angles α to a depth less than the width of the yoke, and the plates of the contour vertical rods 2 are bounded by their corresponding V-shaped angles, in which the tops of the plates 5 of the contour vertical rods are cut off. Production of laminated magnetic core, including stamping of plates of extreme, in-contour vertical rods and horizontal yoke of electrical steel strips, to obtain pre-defined forms, detailed sorting and batching of plates into a closed magnetic conductor, with layer-by-layer displacement of them in packages in the zone of plate junction of vertical rods and horizontal yoke , stamping plates of contour vertical rods, is performed with the help of a tool, the working deforming parts of which form from two to ntsov V-shaped with corners cut off vertices
