In 21st century, with the accelerating process of urbanization, the construction business of the town develops rapidly. Residential community has become the main site of people’s life, study, entertainment and inhabitancy, with high-rise residential building as its vital sign.With the rapid development of science and technology, high-rise building is flourishing towards automation, energy, information and intelligent direction. In particular, the emergence of intelligent buildings, has become the measure of a country or region's economic development and scientific and technological progress as an important landmark. The design is a residential high-rise residential buildings of a certain electrical design.
In this paper, the ground works for the 12-story high-rise all-story residential. Covering an area of about 1300 square meters, the high levels for every is 3.6m. Indoor and outdoor relief is 0.40m. Civil electrical load, according to the building in the political and economic importance or the reliability of electrical equipment to the power supply requirements, divided into three levels. That is one load, second load, three load. The construction works for a class of primary and secondary load power supply, fire fighting system and an important part of the load at the same time dual power supply, power substation caused by the district, three-phase five-wire system, the use of TN-C-S system, the use of tree-type approach to the distribution of power distribution boxes.
Design includes: power supply and distribution system design(system design of fire safety equipments including residential elevator, fire pump, emergency lighting system for evacuating and so on), architectural lighting design, lightning protection and grounding design, television system design, telephone system design and information network system. It focuses on the design of strong electrical parts, the main design of the project is distribution system and lighting system.
