Abstract

UN SENSOR PARA INDICACION DE TENSION CAPACITIVA SE COMPONE DE UNA UNIDAD (1) BASICA CON UN ELECTRODO (3) DE CAPACITANCIA Y UNA TAPA (8) CON OTROS ELECTRODOS (9) DE CAPACITANCIA QUE SE ENCUENTRAN SEPARADOS POR MEDIO DE DISTANCIADORES (7). EL ESPESOR DEL MATERIAL DE LA UNIDAD (1) BASE Y DE LA TAPA (8) ES TAL QUE CUANDO EL INDICADOR DE TENSION ESTA CARGADO LA DISTANCIA ENTRE LOS ELECTRODOS (3,9) DE CAPACITANCIA SE REDUCE SIN QUE SE PRODUZCA NINGUNA FLEXION EN EL PUENTE DE MATERIAL FORMADO ENTRE LOS DISTANCIADORES (7) MEDIANTE COMPRESION DE AL MENOS UNO DE LOS MATERIALES DE LOS QUE ESTA CONSTITUIDA LA UNIDAD (1) BASE, LA CUBIERTA (8) Y LOS DISTANCIADORES (7).
