Diseño de las instalaciones eléctricas de bajo voltaje para la nueva infraestructura de la empresa metalmecánica IMEC considerando criterios de eficiencia energética

Abstract

In this work the electrical design of the new infrastructure of the Metalworking Industry Engineering and Construction IMEC is carried out, which is supplied with energy from a 22.8 kV line that enters a transformer of 150 kVA conion delta-star 22.8/0,220/0.127 kV. Measurements are taken machine conditions and the mode of operation of the industry, in order to size, according to those found in the values of the industry and the manufacturer of the machines: caliber of conductors, protection system and grounding system. The size of the use of the transformer view is the load factors, for the bass circuits are sized the conductors that produce the current capacity and voltage drops, as safety and protection systems is performed sizing the grounding system and the coordination of protections for each circuit. Finally, the fire system is designed
