Abstract
El control y mantenimiento de elementos eléctricos que requieren de un contacto directo, pueden poner en riesgo la vida de las personas dedicadas a ello. Por este motivo, se ha hecho necesario diseñar sistemas que permitan revisar el estado de los equipos y que puedan ser controlados a distancia por el usuario. En este caso, la aplicación se basa en controlar de forma remota la posición de una antena cuya finalidad es localizar fuentes de descargas parciales en los aislantes, y diseñar el sistema de adquisición de datos que recoge la información del fenómeno físico.
Para generar el movimiento automático se empleará una placa Arduino que controlará la posición del servomotor, encargado de situar el sistema en la dirección indicada, y para captar las señales emitidas por las descargas parciales se empleará una antena directiva que enviará los datos a una tarjeta de adquisición.
Este trabajo constituye la base del proyecto “Localización de eventos en radiofrecuencia mediante una antena de alta directividad”, complementario a este. En él, se analizarán las señales proporcionadas por el sistema de adquisición en cada una de las posiciones recorridas por el sistema, y se realizarán varios estudios que determinarán la localización de la fuente de descargas parciales.
The control and maintenance of electrical elements that require direct contact can affect the safety of the staff engaged in it. For this reason, the design of systems that allow to check the conditions of the equipment and that can be controlled remotely by the user has become necessary. In this project, the application is based on the remote control of the position of an antenna whose purpose is to locate sources of partial discharges inside electrical insulators, and to design a data acquisition system that acquire information from the physical phenomenon. In order to generate the automatic movement, an Arduino board will be used to control the position of a servomotor, which is the responsible for locating the system in the right direction; and in order to capture the signals emitted by the partial discharges, a directional antenna will send data to an acquisition card. This work is the basis of the project “Location of events in radiofrequency using a high directivity antenna”, complementary to this. In it, the signals provided by the acquisition system will be analyzed in each of the positions covered by the system, and several studies will be tested to determine the location of the source of the partial discharges.
