Implementación de un tablero de alimentación para el aula 35 de la ESFOT.

Abstract

A power supply board was designed and built for classroom 35, to protect, energize and de-energize 4 work tables, an oil-hydraulic module, four modules for refrigeration loads, a module for pipe losses and four hydraulic modules. The board consists of protection and maneuver elements; each work table and module have on/off switches in their circuits, which together with the contactors allow the passage of current and voltage in each module and/or work table. The board has implemented a voltage and amperage measurement system, which contains three ammeters and three voltmeters connected to each of the phases of that indicate the voltage and amperage on each line. The panel contains a phase loss system, which consists of three phase loss relays of phase and three red pilot lights, each coil of the relay is connected to a phase of the board connection. When a phase is lost on the power board or for reasons that the relay coil is defective or the coil burns due to an overvoltage, the phase with alteration or defect is indicated by the red signal lights, a Once the signal light is on, the circuit opens, leaving the panel inactive.
