Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA DETERMINAR LA MASA VOLUMINICA DE UN GAS DE AISLAMIENTO DE UN APARATO ELECTRICO CERCA DE LAS PIEZAS RECORRIDAS POR LA CORRIENTE, CARACTERIZADO POR QUE COMPRENDE LAS SIGUIENTES ETAPAS: A) SE MIDE UNA TEMPERATURA DE REFERENCIA (T{SUB,REF}) EXTERIOR AL APARATO CERCA DE ESTE, B) SE MIDE LA CORRIENTE (A, IB, IC) QUE ATRAVIESA EL APARATO Y SE DETERMINA, A PARTIR DE LOS VALORES DE CALENTAMIENTO DEL GAS EN FUNCION DEL VALOR DE LA CORRIENTE Y PARA VARIAS TEMPERATURAS DE REFERENCIA, EL CALENTAMIENTO ({DL}T) DEL GAS POR ENCIMA DE LA TEMPERATURA DE REFERENCIA, HABIENDO SIDO ESTOS VALORES DE CALENTAMIENTO PREVIAMENTE DETERMINADOS POR PRUEBAS O POR UN MODELO MATEMATICO, C) SE CALCULA LA TEMPERATURA DEL GAS (T) POR ADICION DE LA TEMPERATURA DE REFERENCIA (T{SUB,REF}) Y DE CALENTAMIENTO ({DL}T), D) SE MIDE LA PRESION (P) DEL GAS EN EL INTERIOR DEL APARATO, E) SE CALCULA LA MASA VOLUMINICA {RH} DEL GAS A PARTIR DE LAS ECUACIONES DE ESTADO {RH} = F(T,P) DEL GAS, QUE SON DATOSTABULADOS.
