Research On The Distribution System Of Machinery Factory

Along with the social development, the electric power system in China industrial production and is widely used in daily life. As is known to all, electricity is modern industrial production of the main sources of energy and motive force of economic development, social life, or power has quickly become one of important energy, so the study of power system are also increasingly important. Electricity is one of the most widely used energy, because it in production, transmission, distribution and transformation, control and management is very easy. So the supply for users of electric power system is an important link of the power supply reliability and power loss also deserves attention. The importance of electricity in industrial production, lies in the industrial production electrified later can be greatly increased yield, improve product quality and productivity, reduce production cost, reduce labor intensity, and conducive to the realization of automatic production process. On the other hand, if the factory of the power supply, a sudden interruption of industrial production may cause serious consequences. Therefore, completes the work for power plant development, realize the modernization of industrial production industry, has the extremely vital significance.But in power system planning and design is to consider some factors. First the power system security and reliability of the operation, Second is the guarantee of good power quality, Once again, is assurance system operation efficiency. Protection is to guarantee the safe operation of the power system and improve the power quality on the important link of the power system, the design of transmission lines to relay protection, the calculation of relative links. Therefore for distribution circuit design and calculation have important practical significance and value.This thesis in some mechanical factory as the research object, this paper discusses the design scheme of distribution circuit factory. Based on the above research object of study material, design background. The distribution of its power lines and load calculation short-circuit calculation, choose the research content requirements, considering the electrical equipment for the external protection scheme...
