Abstract
The invention relates to a method for impregnating an electrolytic capacitor with high voltage and a large shell, which comprises following steps: arranging core claddings in a sifter with holes; putting the sifter into an oven for baking the core claddings with high temperature so as to make the temperature inside the core claddings reach 65 to 115 DEG C; putting the core claddings into a soaking boiler; an impregnating boiler is needed to be preheated; vacuumizing the impregnating boiler to make the core claddings at negative pressure state; sucking electrolyte solution into the impregnating boiler for several times to make the electrolyte solution liquid surface exceed the core cladding surfaces for 5 to 30 cm; wherein the electrolyte solution is needed to be preheated; and perform impregnation at the circulating state of negative pressure-ordinary pressure-positive pressure-ordinary pressure. By adopting the method provided herein, the impregnating time can be greatly shortened; and the impregnating effect is improved.
