Diseño e implementación de un tablero con arrancador estrella-triángulo para motores trifásicos para prácticas en el laboratorio de control

Abstract

In the Ecuador and around the world in general there is a lot of companies and factories with motors of all kinds, either continuous or alternative power, between the alternates exist single-phase or three-phase, of which three-phase have different types of connections and arrangements such as delta and star connections and direct arrays, star-triangle, winding rotor, autotransformer and stator resistances. The arrangements usually depend of the situation in which the engine will work, but usually, the most common and most used are the direct arrangements and the star, triangle. One of the benefits of the star-delta starting and why is the newest of the most used start-ups in energy saving at the time of ignition of the engines in their current peaks, since this allows The current you need to start the sea much less until the break of the pair and then pass a delta to perform the work of force. It should be noted that the cost of realizing this is much lower than the other alternatives we have for saving energy consumption when starting a three-phase motor, such as the soft starter and variable speed drive. The objective of this work is to provide the benefits of the implementation of the star-delta arrays for three-phase motor.
