Abstract
La presente invención se refiere a un método para reemplazar un refrigerante que contiene PCB en un aparato de inducción eléctrico, que tiene un tanque que contiene el refrigerante, un arrollamiento eléctrico y aislamiento eléctrico celulósico, sólido, poroso, sumergido en el refrigerante que contiene PCB con un refrigerante permanente dieléctrico, de ebullición elevada, substancialmente exento de PCB, para convertir el aparato eléctrico en uno en el que el régimen de elución de PCB hacia el refrigerante es inferior al régimen máximo permisible de elución hacia el refrigerante de un aparato eléctrico clasificado como sin PCB, el aislamiento eléctrico, poroso, sólido estando impregnado con el refrigerante que contiene PCB.The present invention relates to a method of replacing a PCB-containing refrigerant in an electrical induction apparatus, having a tank containing the refrigerant, an electrical winding, and solid, porous cellulosic electrical insulation immersed in the PCB-containing refrigerant with a permanent high boiling dielectric coolant, substantially PCB-free, to convert the electrical appliance into one in which the rate of elution of PCB into the coolant is less than the maximum allowable rate of elution into the coolant of a classified electrical appliance As without PCB, the electrical insulation, porous, solid being impregnated with the refrigerant containing PCB.
