Abstract

Un sistema colector de corriente con escobillas macizas que comprende una máquina dinamoeléctrica que tiene un estator y un rotor soportado en el mismo y dispuesto para cooperación electrodinámica con él; al menos un colector de corriente en dicho rotor que recoge corriente durante el funcionamiento de la máquina; escobillas colectoras de corriente macizas, montadas en porta-escobillas en dicha máquina, estando dichos porta-escobillas posicionados para permitir contacto de escobilla con dichos colectores de corriente; medios que encierran dicho colector de corriente y escobillas en una cavidad sensiblemente hermética, cerrada a la atmósfera; medios para hacer circular un gas a presión a través de dicha cavidad; caracterizado porque dicho gas tiene mezclado con el mismo un aditivo que comprende una sustancia orgánica vaporosa que permite una caída de tensión en las escobillas no mayor que 0,2 voltios y un régimen de desgaste de escobillas no mayor de 20 milímetros cúbicos de desgaste por megametro de recorrido deslizante mientras funcionan a una temperatura justo inferior que la temperatura volumétrica crítica de escobillas.
