System Multiple-factor Analysis of Design Parameters Calculation of Welding Reactors

The article presents the concept of multi-factor system approach for the optimization of material consumption of electrical welding reactors based on numerical methods. It was shown that total cost components are expressed in terms of the size of welding transformers, reactors, and electromagnetic loads (current density in windings, induction into steel), that in the future will permit to find the characteristics, providing a combination of optimum design parameters of electrical equipment and their possible nominal and peak loads. At the same time, the analytical optimization is a difficult and time-consuming task, that is why earlier it was impossible to take into account a number of important factors not related to a simple analytical dependence, which would define the price, depending on manufacturability, reliability and durability by a short circuit, load capacity and other factors. The structural and analytical electrical circuit of design synthesis of electrical reactors was developed. The dependences of the masses and the corresponding to them electrical losses at a minimum of the objective function for a given inductance of the reactor were obtained
