摘  要

 众所周知，电在人们的正常生产生活中已经占据了不可估量的地位。特别是在工厂，企业当中。没有电，人们就不能从事任何生产活动。所以怎样进行工厂供配电以及工厂供配电系统的优化设计成了当今供配电方面的重要课题。传统的供电方式已经不能跟上现代社会快速发展的脚步了。随着社会生产方式的转变和更新，社会生产力的不断向前发展，人们已经不断发明和制造出了不计其数的各种性能优越的工厂供配电零部件，从而使得工厂供配电系统的设计发生了翻天覆地地变化。当人们使用了这些先进的零部件之后，不仅工厂供配电的方式得到了创新，而且其质量也得到了前所未有的提高。因此，自己动手设计工厂供配电系统是一件非常具有现实意义的事情。

Abstract

 It is well known, the electricity already occupied the inestimable status in people's regular production and life.Specially in factory and enterprise.Without the electricity, the people cannot be engaged in any production activity. Therefore how carries on the factory designs for the power distribution as well as the factory for the electrical power distribution system optimization has now supplied the power distribution aspect the important topic. The traditional power supply way already could not follow the footsteps of the modern society fast development.
Along with the social productive way transformation and the renewal, the social productive forces forward developed unceasingly, the people already unceasingly invented and make the countless each performance superior factory for the power distribution spare part, thus enabled the factory to occur earth-shakingly for the electrical power distribution system design changed. After the people have used these advanced spare parts, not only the factory obtained the innovation for the power distribution way, moreover its quality also obtained the unprecedented enhancement.Therefore, I begin to design the factory has the practical significance matter extremely for the electrical power distribution system by myself.

Keywords the factory for the electrical power distribution system; design optimal
