摘要:
The present invention relates to a method for filling an electrical device for medium and high voltage transmission and/or distribution networks using a multicomponent insulating filler. The method is characterised by the fact that it comprises the following phases:
a) mixing the various components of the insulating filler separately with compressible microspheres; b) measuring the viscosity of the various components mixed with said microspheres at regular intervals; and when they have a substantially uniform viscosity c) mixing the various components obtained in said phase a) to obtain the multicomponent insulating filler; d) filling the free volume V with the multicomponent insulating filler obtained in said phase c), having previously extracted the air present in the free volume V using a vacuum pump; e) injecting a further quantity of insulating filler in overpressure.
