TECHNICAL FIELD
[0001] The utility model relates to amorphous alloy dry-type transformer assembly tool technical field, especially in kind of amorphous alloy plane core core column upper iron yoke overturning and erecting device. BACKGROUND
[0002] With the rapid development of social economy, the demand for electricity is also increasing, and the performance of the transformer as an important link in the power transmission and distribution network directly affects the operating cost. The size of the transformer no-load loss and load loss determines its performance level. Amorphous alloy transformer greatly reduces the no-load loss and no-load current of the transformer because of the use of amorphous alloy core material. Its no-load loss is about 70% lower than that of traditional silicon steel sheet core products, and the no-load current is reduced by 60%, which has great energy-saving advantage.
[0003] The core of such a transformer is made of amorphous alloy strip. The core needs to be made into an overlapping type with an upper opening. Before the coil is assembled, the overlapping upper yoke core needs to be turned over and erected. Since the amorphous alloy core sheet is very soft and brittle, it is easy to break and collapse during the overturning and erecting process. The broken core sheet not only increases the no-load loss of the transformer, but also causes safety accidents when the broken core sheet falls into the coil. Therefore, the core overturning and erecting of the amorphous alloy transformer is the most complex and difficult process in the assembly. Figure 1 and Figure 2 As shown in Figs. 1 and 2, the previous core column upper iron yoke overturning device is a two-section U-shaped metal support 100 welded on a loose-leaf hinge 200. The two-section U-shaped metal support 100 can rotate 180 degrees around the loose-leaf hinge 200, and two groups of height-adjustable support frames are provided. When the core is turned from flat to vertical, the change in bending radius will generate a large friction force between the amorphous alloy sheet and the metal support 100, which will cause the amorphous alloy sheet to bend and break, affecting the performance of the product.
