Abstract
This design take the national correlation standard as a criterion, uses electricity, the frugal energy take the security as the instruction, focuses in enhances the general populace's material, the cultural life, manifests the well-off social material rich and life happiness, the application modern electricity technology, has completed this commercial-residential buildings power distribution, the power, the illumination, the earth anti-radar, the fire prevention system design.
In power distribution design, according to load rank, determination power supply way and system plan; In the design by the emanate wiring, has guaranteed the power supply reliability; Using needs the method of correlates to carry on the computation load, according to the stipulation choice protection electric appliance, the electric wire electric cable, achieved uses electricity safely and saves the energy goal. In the lighting system design, in line with the principle which conserves energy, chooses the fluorescent lamp is the photo source, through the degree of illumination computation, determined the best photo source number, has created one comfortably, the bright life, the leisure environment for the people; The plug installs the design avoided towing the forming block abusiveness, satisfied the increase current collector the demand, enhanced the security which used electricity. The dynamic system design, completes the electrical machinery the main circuit and the control circuit design, has realized the electrical machinery safe operation. Earths in the anti-radar design, through flat steel and ground steel bar structure docking, anti-radar, earth public earth body, both has safeguarded the earth security, and saved the earth equipment. In the fire prevention system design, through the feeling smoke, the feeling warm detector, the manual fire reports to the police the button, fire prevention electrical equipment and so on hose saddle button arrangement, the installment design, has realized to each area of fire protection fire protection monitor, the survey fire occurrence. At the same time, the fire prevention system design, will survey, the monitoring and the manually controlled alarm system and the fire broadcast, Fang  the curtain gate and the fire pump unites, realization fire prevention linkage, when will have the fire, the survey, the monitoring and the hand-controller system will send out the fire signal, will have various system to send out the warning, will carry on the fire protection to isolate and to start the automatic fire fighting system, while will disperse personnel's to carry on the automatic fire fighting, the control, the elimination fire hidden danger, will safeguard in this building the personnel, the property safety.
 
Keywords The commercial-residential buildings；Electricity design；Power distribution；Illumination；Fire prevention
