Abstract
This thesis mainly expounds the nanchang city xiangyushangcheng residential area’s distribution system is designed based on the design of electrical engineering, design principles and methods of the conclusion, etc. Mainly shows XL - 21 low power distribution characteristics of the ark, the design process of the various components required technical parameters, according to the size of the current electricity load calculation, determined to correspond to the ampacities and wires, and copper platoon with actual requirements for Auto CAD software system, cabinet put oneself in another's position, second schematic diagram of the complete design. With the rapid growth of the new economy, power load demand is growing rapidly and in order to improve the convenience of using electric power terminal, flexibility and reliability, the development and application of low voltage distribution ark becomes more and more important. Entering the 21st century, according to the new technology development, China has entered the intelligent low-pressure electrical appliances, communications fourth-generation products. With intelligent, communication as the main feature of the new-type low-voltage products will be the main aspect in electrical development.
Keywords: low voltage distribution, Distribution system, XL - 21 type, Complete design
