Diseño y construcción de un tablero de transferencia automática para las líneas de producción de la empresa Resiflex Duraflex S.A.

Abstract

This topic refers to the design and construction of an automatic electrical energy transfer board. For this purpose, it is taken into account the use of equipment that facilitate the automatic process such as: PLC LOGO, voltage supervisors, UPS, three-phase contactors, thermal relays, among others. All these equipments are connected to each other and they will be in charge of sending signals to the PLC LOGO regarding the presence or absence of local electric power, which the PLC LOGO will then send the signal to turn on and off the generator. This board contains the options to be modified according to the user's needs thanks to the PLC LOGO equipment. In the same way, a parameter that allows the generator to start once a week was managed in order to keep the equipment operational and not to present failures at the moment of an electrical blackout. To ensure that the transfer board always remains in operation, the entire control system has been built at a voltage of 120VAC, which will be powered by an external source (UPS), which will have the advantage of maintaining correct operation for hours until the local power supply is restored. In the event of failures in the automatic system, a manual system is implemented by means of key selectors to control the generator, without jeopardizing the automatic system. All automatic systems allow all the processes to which they are assigned to be carried out in a more efficient way and in less time.
