Abstract

The design entitled wutongxinyuan 18# block electrical system design, this building is a class of high - rise building.His building isb-class building, its residential living electricity belongs to the three - level loading, second lightning building design. In the design task, required to complete wutongxinyuan 18# residental building，s A block strong electric, weak electricity system design, Main content are as follows:

Illumination and socket design, in addition to the General requirements, taking both its energy-saving and convenient and practical into account.

Low - voltage power supply system for the TN-C-S system, voltage is 380/220V, the use of radial or trunk – powered system.

Lightning protection and grounding system design, the lightning protection design of this project under the second category. Repeat grounding and lightning protection grounding and power supply grounding device of weak current system Earth share, their joint resistance ≤ 1 .

Cable TV systems, the engineering design by allocation - branch system, television signal transmission in coaxial cable buried directly introduced into the House of telecommunications in one box.

Telephone and data network system, telephone system from transfer box trunk wiring to all levels of telecommunications in one box, data network system by a network switch to radial wiring to all levels of telecommunications in one box.

This design has completed 16 engineering diagrams, these basic meet national construction drawings for electrical design specifications and standards. Through graduation design, deepen the understanding of theoretical knowledge and application expertise for future work to lay a foundation.

Key words: Lighting; Sockets; Power supply and distribution; Lightning and grounding; Cable televisio
