[Abstract]:It is the main policy of our country to develop energy saving and environmental protection industry and to popularize high efficiency energy saving products. The amorphous alloy iron core distribution transformer is one of the most important equipments of energy saving and environmental protection in distribution system. The manufacturer ensures its reliable operation at the same time. The core task of transformer design is to find the optimal solution of engineering cost. At present, the design of amorphous alloy transformer in our country has high design cost, low design efficiency and long design period. Since the technology development is not mature, it is necessary to study the above problems. The amorphous alloy iron core distribution energy saving transformer appears late, so it is compared with the ordinary transformer. Its superiority has not been deeply concerned and studied. Therefore, this paper optimizes and improves the amorphous alloy iron core distribution energy saving transformer in design, production, manufacture and process. The main work is as follows: 1.Computation and analysis of amorphous alloy core distribution transformer with energy efficiency grade 2 and ordinary oil-immersed distribution transformer with energy efficiency grade 3. The cost consumption of ordinary transformers and amorphous alloy transformers is compared, and the basis of transformer selection is provided for the majority of transformer users. 2. According to the structural characteristics of rectangular cores and coils of amorphous alloy transformers. The short circuit impedance of amorphous alloy core transformer is calculated by using the equivalent method and the energy method, and the equivalent method is applied to the electromagnetic calculation according to the relation between the diameter of the circular core and the capacity. The relationship between the core thickness and the capacity of amorphous alloy products is deduced, and the formula of calculation experience is given. 3. The electromagnetic design principle of amorphous alloy core distribution energy saving transformer is introduced and analyzed. In the process of electromagnetic design, the constraint conditions are added, and the electromagnetic calculation is optimized by MathCAD software to find the optimal solution. The key data parameters in the calculation results are input into the EXCEL software. Through programming and adding graphics, the parameterized design of the product structure data is realized. 4. From the point of view of saving energy, saving materials and improving efficiency, the manufacturing process of amorphous alloy transformer is improved. For example, the design of coil adjustable die and the improvement of tooling equipment can improve the production efficiency of foil type, cylindrical coil winding and assembly of the body, and realize the further optimization of production cost.
