The document titled "Xingping Chemical Fiber Wool Mill Total Distribution Substation and High Voltage Power Distribution System Design" outlines the design and implementation of the power supply system for the factory. The power supply system is responsible for stepping down the electricity from the grid and distributing it to various buildings and workshops within the factory premises. It consists of the factory's step-down substation, high-voltage distribution lines, workshop substations, low-voltage distribution lines, and electrical equipment. The design of the factory's total step-down substation and distribution system is based on the load requirements and characteristics of each workshop, the production process's demand for loads, the layout of loads, and national power supply conditions. It aims to provide a safe, reliable, and economically viable distribution of electrical energy to all departments. The key aspects of the design include load calculation and reactive power compensation, selection of substation site, calculation of short-circuit current and setting of relay protection, selection of primary electrical equipment, selection of the number and capacity of transformers for workshop substations, and design of lightning protection and grounding devices. The key words related to the design process include load calculation, short-circuit current calculation, transformers, and lightning protection. The document emphasizes the importance of proper design and implementation of the power distribution system to ensure the safety, reliability, and efficiency of electrical energy distribution within the factory. By addressing these key aspects in the design phase, the factory can optimize its power supply system for optimal performance and cost-effectiveness.
