Description

Technical Field

[0001] The utility model relates to the technical field of assembly tooling for amorphous alloy dry-type transformers, in particular to an auxiliary tooling for flipping and erecting an iron yoke on an amorphous alloy dry-type transformer. Background Art

[0002] With the rapid development of the economy, the demand for electricity is also increasing. As an important link in the transmission and distribution network, the performance of the transformer directly affects the operating cost. The no-load loss and load loss of the transformer determine its performance level. The amorphous alloy transformer uses amorphous alloy core materials, which greatly reduces the no-load loss and no-load current. Its no-load loss value is only about 30% of that of traditional products, which has great energy-saving advantages. In the implementation of national carbon standards and carbon neutrality measures, amorphous alloy transformers have received attention from major national departments, and the proportion of amorphous alloys in power grids at all levels is also increasing.

[0003] The iron core of this dry-type transformer is made of amorphous alloy strip, and the iron core needs to be made into an overlapping type with an upper opening. Before installing the coil, the overlapping upper iron yoke core needs to be flipped and erected. Since the iron core is very soft and brittle, it is very easy to break and collapse during the flipping and erecting process. The broken iron core pieces will not only increase the no-load loss of the transformer, but the broken iron core pieces falling into the coil will also cause safety accidents. Therefore, the flipping and erecting of the iron core of the amorphous alloy transformer is the most complex and difficult part of the installation process. Utility Model Content

[0004] The utility model aims to provide an auxiliary tooling for flipping and erecting the iron yoke on an amorphous alloy dry-type transformer, which reduces the difficulty of assembly, reduces the number of damaged amorphous strips, improves product performance, and improves production efficiency and assembly quality.

[0005] In order to solve the above technical problems, the utility model provides an auxiliary tooling for turning and erecting the upper iron yoke of an amorphous alloy dry-type transformer, comprising two sets of turning components and two sets of lifting support frames;

[0006] Two groups of the flipping assemblies are symmetrically arranged on both sides of the amorphous alloy iron core column, and are used to lift the multiple transformer upper iron yoke amorphous sheets stacked on both sides of the amorphous alloy iron core column, and the flipping assemblies can lift the transformer upper iron yoke amorphous sheets and flip them upright;

[0007] The two groups of lifting support frames are symmetrically arranged on both sides of the amorphous alloy iron core column, and are used to support the horizontal flip assembly, and the lifting support frames can be lifted and lowered in the vertical direction to adjust the height of the flip assembly.

[0008] Preferably, the flip assembly comprises an upper flip support plate and a lower flip support plate, and the upper flip support plate and the lower flip support plate are rotatably connected to each other via a movable hinge.

[0009] Preferably, the flip lower bracket is connected to the amorphous alloy iron core column by a binding belt, and ensures that the hinge is flush with the upper end of the amorphous alloy iron core column; when the flip upper support plate flips 90 degrees around the hinge, the amorphous iron sheet on the transformer is lifted and flipped upright.

[0010] Preferably, the lifting support frame includes a screw rod, and an upper support plate and a lower support plate are respectively connected to both ends of the screw rod, the lower support plate is supported on the assembly workbench, and the upper support plate supports the flip upper support plate of the flip assembly.

[0011] Preferably, the upper support plate and the lower support plate are threadedly connected to the screw rod, so that the upper support plate and the lower support plate can be adjusted in height on the screw rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The use of the flipping and erecting auxiliary tooling of the utility model reduces assembly time and improves assembly efficiency; with the support and protection of the tooling, the number of broken strips of the amorphous alloy core during the flipping and erecting process is reduced, avoiding the situation where the core performance is significantly deteriorated, and ensuring that the no-load loss of the transformer is at a low value.

[0023] The utility model provides an auxiliary tooling for turning and erecting the iron yoke on an amorphous alloy dry-type transformer. Figure 1 and Figure 2 , including two groups of flipping components 1 and two groups of lifting support frames 2; the two groups of flipping components 1 are symmetrically arranged on both sides of the amorphous alloy iron core column 3, and are used to lift the multiple pieces of transformer upper iron yoke amorphous chips 4 stacked on both sides of the amorphous alloy iron core column 3, and the flipping components 1 can lift the transformer upper iron yoke amorphous chips 4 and flip them upright; the two groups of lifting support frames 2 are symmetrically arranged on both sides of the amorphous alloy iron core column 3, and are used to support the flat flipping components 1, and the lifting support frames 2 can be lifted and lowered in the vertical direction to adjust the height of the flipping components 1.

[0024] For details, please refer to Figure 3 and Figure 4The flip assembly 1 includes a flip upper support plate 101 and a flip lower support 102. The flip upper support plate 101 and the flip lower support 102 are rotatably connected via a hinge 103. The flip lower support 102 is connected to the amorphous alloy iron core column 3 via a binding belt 5, and ensures that the hinge 103 is flush with the upper end of the amorphous alloy iron core column 3. When the flip upper support plate 101 flips 90 degrees around the hinge 103, the amorphous alloy iron core column 4 on the transformer yoke is lifted and flipped upright.

[0025] Specifically, the lifting support frame 2 includes a screw rod, and an upper support plate and a lower support plate are connected to both ends of the screw rod, respectively. The lower support plate is supported on the assembly workbench, and the upper support plate supports the upper flip support plate 101 of the flip assembly 1. The upper support plate and the lower support plate are threadedly connected to the screw rod, so that the upper support plate and the lower support plate can be adjusted in height on the screw rod.

[0026] When the amorphous alloy dry-type transformer is equipped with the transformer coil, the upper iron yoke flipping and erecting auxiliary tooling of the present invention is used. First, the flip lower bracket 102 of the flip assembly 1 is tied together with the transformer core column to which the coil is to be installed with a binding belt 5, and the hinge 103 of the flip assembly 1 is ensured to be flush with the position of the iron core to be flipped and erected. At this time, the flip upper support plate 101 of the flip assembly 1 is flipped and placed flat on the height-adjustable lifting support frame 2. In the next step, the upper yoke part of the transformer core column is flipped according to the transformer upper iron yoke amorphous crystal 4 when stacked. Place it flat on the flip upper pallet 101. When the transformer upper yoke non-chip 4 of the upper yoke is flipped over, the transformer upper yoke non-chip 4 can be erected by quickly flipping the flip upper pallet 101 of the flip assembly 1, and the flip upper pallet 101 and the erected transformer upper yoke non-chip 4 are tied together with a binding belt. After the coil is sheathed on the core column, the erected flip upper pallet 101 is flipped and laid flat on the lifting support frame 2. Finally, the two sides of the upper yoke non-chip 4 are alternately restored to their original shape and position, and the coil sheathing work is completed. Figure 5 The use of the flip and erection auxiliary tooling of the utility model reduces assembly time and improves assembly efficiency; with the support and protection of the tooling, the number of broken strips of the amorphous alloy core during the flip and erection process is reduced, avoiding the situation where the core performance is significantly deteriorated, and ensuring that the no-load loss of the transformer is at a low value.
