High-rise Building Distribution Systems And Lightning Protection Engineering Design Studies

With the development of modern times society, enlarge of building's scale, more and more electrical equipment is applied to building. Especially, with the popularization of computer network information technology, more and more information electrical equipment is applied to building; it brings a few new questions. In order to improve the reliability of power distribution system of high building, choice capacity of power distribution device rightly, it is necessary to calculate charge rightly, the author analyses and investigates relative question with charge calculation, expatiates particularly capacity choice of important equipment , puts forward these measure being used to improve the reliability of power distribution system , makes charge calculation combination to project example, the result shows that these means is right and reasonable, these means can guide project practice .Tradition low voltage power distribution system mostly emphasizes over loading protection and short circuit protection but these measure can only protect electrical equipment and power supply circuit, lately, people put forward the viewpoint that person safety and fire protection, therefore, for electric design of high building and rich residence, people should firstly think over person safety and fire protection. The author investigates the reason of fatalness of person touch electricity and fire when existing residual current, puts forward correspond protect measure.High building is easy suffered from lightning stroke, in case being suffered lightning stroke, it should bring huge losing, lightning protection system of common building can not protect electronic device, on the contrary, it may introduce lightning therefore high building's lightning protection is more important. The author analyses and research these question of over voltage and electro-magnetism compatibility of lightning stroke, puts forward these means of lightning protection of electron device in high building.Research and resolve of above-mentioned question helps to improve quality of electric design and project practice...
