Electrical Design Of Multi-functional Exhibition Hall Of Zhuhai Air Show Center

With the rapid development of economy and the improvement of people’s living standards,China’s exhibition industry has developed.With the rapid development of urban economy and culture,today’s exhibition building has gradually become the hot spot of urban architectural design.Among them,exhibition space is the most basic and important component of exhibition activities.In the exhibition building,electrical design has become an indispensable part.Different from the general civil buildings,exhibition buildings have the characteristics of high space and large span.It is also because of the special architectural characteristics of exhibition buildings,compared with the general civil buildings,there are great differences in electrical design,which also makes it put forward higher requirements for the safety and reliability of the overall electrical design.Based on the analysis of the development needs of contemporary exhibition buildings and the research hotspots of electrical design of exhibition buildings at home and abroad,this paper takes the electrical design of multi-functional exhibition hall No.9-11 of Zhuhai Air Show Center as an example to analyze the electrical design needs of tall space including the air show exhibition hall.On this basis,combined with the electrical design example of Zhuhai Aviation exhibition hall,the paper analyzes,studies and demonstrates the problems and focuses found in the design process.This paper mainly includes the following three electrical system design analysis and research:Power supply and distribution system: through the analysis of the design basis including project overview and load level division,the power supply scheme,substation setting,high voltage power supply and distribution system and low voltage power supply and distribution system of the building are determined;According to the particularity of the air exhibition hall,the low-voltage distribution route design scheme of indoor pipe trench laying power distribution is proposed and adopted innovatively.Lighting system: Based on the analysis of the building lighting requirements including lighting lamps and light sources,lamp efficiency,lighting power density and illumination,combined with the architectural characteristics,first determine the specific technical parameters of light sources and lamps,then carry out the general lighting design of the exhibition hall,and simulate and verify the design results through Dialux software.In addition,combined with the established evacuation flow line and specifications,the layout design of emergency lighting is carried out.Fire protection system: according to the architectural characteristics of the air show,the fire characteristics of the air show exhibition hall are analyzed.Combined with the fire characteristics,the existing detection technology is analyzed and compared.Under the conditions of meeting the architectural,structural characteristics and specifications,the detection scheme of combining linear beam smoke detector and infrared dual band flame detector is innovatively proposed and adopted,The layout scheme of the detector combination is mainly introduced.Finally,the design of electrical fire monitoring system in large space is briefly introduced.
