The theme of the graduation work: "Reconstruction of the power supply sys-tem of an enterprise for the manufacture of weighing equipment".The volume of the project is: 59 pages of text, 13 figures, 13 tables, 65 formulas, 15 sources of literature.Object of study: an enterprise for the manufacture of weighing equipment.The purpose of the project is to develop a project for the reconstruction of the enterprise's power supply system to ensure its reliable and safe operation, and increase energy efficiency.During the implementation of the project, the existing power supply system and electrical equipment were analyzed, shortcomings were identified, and measures for reconstruction were developed. To select new modern electrical equipment, actual electrical loads, estimated operating currents for production areas, short circuit currents (SC) are calculated. Power equipment is selected, testing of existing and new equipment is carried out. Separate sections are devoted to safety and environmental protection.The results of the work can be recommended in the design of new and reconstruction of existing power supply systems for industrial enterprises, the reconstruction of the power supply system of the enterprise under consideration for the manufacture of weighing equipment. |
