Implementación del sistema eléctrico para un banco de pruebas: motor banda - disco para LTI-ESFOT.

Abstract

The present degree work describes the design, construction and implementation of the electrical system for a belt-disc motor test bench, which will serve as a tool in the academic training and professional development of future students in the career in Electromechanical Technology of the ESFOT (Technologist Training School) at the National Polytechnic School. To achieve the aforementioned, an electrical panel was used on a work table in the LTI (Laboratory of Industrial Technology) (classroom 33) to turn the system on and off, said system is made up of electromechanical elements such as: a contactor that performs the task of connecting the power supply in the power circuit, maneuvering elements such as buttons and switches that were implemented for the control circuit, electronic equipment such as the frequency variator for starting electric motors; and, finally, power consumption elements such as the threephase motor. For the dimensioning of electrical conductors and protections, the NEC standard (Ecuadorian Construction Standard) was considered, in which it stipulates the electrical safety guidelines for indoor installation. Tests of electrical operation of the system were also carried out, these were applied for electrical protections in overload conditions, the starting and stopping of the motor is also checked by means of the maneuvering elements of the panel. Finally, an electrical manual is elaborated that focuses on the description of the components of the electrical system, operation and configurations necessary for the starting of the threephase motor.
