Title Some chemical fiber total distribution substation woolen mill (belt - workshop substation high voltage distribution) and high voltage power distribution system design
Abstract The main purpose of this paper is the power supply design for chemical fiber woolen mill. The main task of it is to ensure electrical energy from the power supply to the electricity department, Safe, reliable, economic and high quality. It must strictly abide by state's relevant laws、regulations、standards and specifications and must proceed from the global, reasonably determine the overall design scheme. Factory design includes the contents of distribution are: load calculation, calculation of reactive power compensation; the choice of the distribution of the site and type; the selection of main transformer substation sets, capacity and type; As a main wiring scheme of power distribution design; the calculation of short-circuit current; the selection of distribution of a device; the way of distribution of the secondary loop and selection and setting of relay protection device; distribution of the lightning protection and grounding device design; and selection of electrical equipment.
Keywords Factory power supply Load calculation The main wiring scheme Relay protection Electrical equipment
