Abstract:This dissertation was Based on Runtian Duhui community of Guannan county, Jiangsu province, the relevant design related to this dissertation was implemented by combining DB knowledge acquired at campus with field background of community, thereby designing comprehensive DB system of community.

　　　First of all, this thesis give brief introduction to integrated development of domestic residence community. Then DB grid of community was calculated by combining basic information of community designed in this thesis. Based on the above calculation, after High and low voltage power distribution system of community and equipment needed in this design were elaborated, the type of Transformation and distribution equipment in the community was completed, and relevant protection, as well as lightening  guard was arranged as well, resulting in all design about Transformation and distribution system of community being completed finally.
