Estudo comparativo a respeito do impacto causado pela instalação de diferentes tipos de chaves seccionadoras em termos de dimensões das subestações de alta e extra alta tensão.

Abstract

In this study, we delve into the various types of disconnect switches commonly employed in high and extra high voltage substations. The primary objective of this research is to conduct an analysis of the impact caused by the use of the main switches utilized in the transmission sector, with the aim of providing a comprehensive understanding of their characteristics and influences on the operation and layout of substations. To achieve this goal, we initially conducted a thorough review of existing literature, seeking to comprehend the various types of disconnect switches available in the market, along with their technical specifications, advantages, and limitations. This initial phase of research allowed us to establish a solid knowledge base on the subject, which was fundamental for subsequent analyses. Subsequently, different physical arrangement plans and layouts were designed, featuring various equipment configurations and disconnect switch arrangements. This enabled us to simulate a variety of operational scenarios and identify potential impacts resulting from the use of each type of switch on other crucial components of substations, such as conduits, grounding systems, earthworks, and foundations. Therefore, a comprehensive and meticulous analysis is essential to ensure the safe and efficient operation of a high-voltage substation.
