Resumo
A descarga atmosférica é um fenômeno meteorológico que pode causar danos
significativos a seres vivos e equipamentos. Tal fenômeno envolve a
transferência de uma grande quantidade de energia elétrica entre a atmosfera e
a superfície terrestre. A engenharia desempenha um papel fundamental na
concepção do projeto, estruturas, edifícios e instalações industriais resistentes a
raios, e não menos importante o dimensionamento adequado, pois é essencial
para mitigar os riscos associados. Para isso, é necessário levar em consideração
variáveis como a localização geográfica, a frequência de tempestades e a
natureza das estruturas a serem protegidas. Além disso, é importante destacar
a ameaça que as descargas atmosféricas representam para seres humanos e
outros seres vivos, uma vez que as correntes elétricas envolvidas podem causar
lesões graves ou fatais. Este trabalho teve o objetivo demonstrar a formação de
raios na natureza, calcular locais que estão sujeitos a descargas conforme
probabilidade em referências do instituto nacional de pesquisas espaciais entre
outras fundamentações teóricas. Realizou-se um estudo de caso, apresentando
projeto de SPDA para um prédio residencial fictício de oito andares, em endereço
na cidade de Osasco/SP, exemplificando a seleção do tipo de SPDA, número de
descidas para aterramento de malha, levantamento de materiais, e
gerenciamento de risco para aplicação de sistema de proteção contra descargas
atmosféricas
Atmospheric discharge is a meteorological phenomenon that can cause significant damage to living beings and equipment. This phenomenon involves the transfer of a large amount of electrical energy between the atmosphere and the Earth's surface. Engineering plays a fundamental role in the design of lightning-resistant projects, structures, buildings and industrial facilities, and no less important is adequate sizing, as it is essential to mitigate the associated risks. To do this, it is necessary to take into account variables such as geographic location, the frequency of storms and the nature of the structures to be protected. Furthermore, it is important to highlight the threat that lightning strikes pose to humans and other living beings, as the electrical currents involved can cause serious injuries or fatalities. This work aimed to demonstrate the formation of lightning in nature, calculate locations that are subject to discharges according to probability in references from the national institute for space research, among other theoretical foundations. A case study was carried out, presenting an ADPS project for a fictitious eight-story residential building, at an address in the city of Osasco/SP, exemplifying the selection of the type of SPDA, number of descents for mesh grounding, lifting of materials, and risk management for the application of Atmospheric discharges protections systems.
