Abstract
The invention relates to a processing method for a combined protection layer of a solid-sealed polar pole, which includes the following steps: a, abrasive blasting pretreatment: cleaning the surface of a casing of a solid-sealed polar pole piece to remove visible oils, grease and dirt on the surface of the casing; b, abrasive blasting: placing the cleaned solid-sealed polar pole piece on a sand blasting machine, and performing the abrasive blasting treatment on the surface of the casing of the solid-sealed polar pole piece; c, aluminum spraying: spraying an aluminum layer on the surface of the solid-sealed polar pole piece subjected to abrasive blasting through electric arc spraying or plasma spraying, wherein aluminum wire material or aluminum powder is taken as spraying material; d, insulating paint spraying: spraying insulating paint on the aluminum layer sprayed surface except an electrified display port, an observation window and an earth terminal, of the solid-sealed polar pole piece sprayed with the aluminum layer. Through the adoption of the processing method for the combined protection layer of the solid-sealed polar pole, provided by the invention, the outer surface of the casing of the solid-sealed polar pole is sequentially sprayed with the aluminum layer and the insulating paint layer serving as the combined protection layer, so that the surface of the solid-sealed polar pole provided with the combined protection layer is all-insulating and contactable, and the solid-sealed polar pole is highly safe.
