Abstract

Métodos integrados para la determinación del envejecimiento, corrosividad, huella y/o contaminantes así como el diagnóstico funcional, la descontaminación, la despolarización y la detoxificación de aceites y fluidos técnicos como aceites minerales aislantes, ésteres naturales y/o sintéticos, lubricantes, fluidos hidráulicos, diatérmicos y técnicos en general, utilizados en transformadores eléctricos, reactores, aisladores, interruptores y turbinas, para la generación, transmisión, distribución y uso de electricidad, dichos métodos se basan en una o más de las siguientes opciones: I - prueba de corrosividad acelerada para el aceite, preferiblemente a 150°C por 12 horas, en la presencia de cobre con calor específico y aparato de agitación, y II - envejecimiento acelerado del aceite, preferiblemente a 120°C por 24 horas, en la presencia de cobre con calor específico y aparato de agitación, dichos métodos se caracterizan por componerse de los pasos para preparar viales con volumen desde 10 hasta 100ml en una mesa giratoria especializada que tiene espacio para 1 a 100 viales. Se purgan gases en sobrepresión con respecto al ambiente para la saturación de los viales, donde estos gases son argón y nitrógeno, se introduce el aceite en los viales y se sellan los viales con tapas para mantener una atmósfera controlada.
