Abstract

The invention discloses a shielding paper processing method, which comprises: raw material selection: selecting aluminum foil paper and high-voltage electric cable paper; adhering: integrally the aluminum foil paper and the high-voltage electric cable paper through an adhesive; drilling: drilling holes on the adhered aluminum foil paper and the adhered high-voltage electric cable paper by using afine pinhole drilling machine; and winding: winding the shielding paper with the holes on a transformer. According to the present invention, the aluminum foil paper and the high-voltage electric cablepaper are adhered, and the hole is drilled on the aluminum foil paper and the high-voltage electric cable paper, such that oil can be effectively immersed, the shielding can be effectively formed, and the electric signal can be effectively shielded; and by using the non-acid non-fat adhesive, the acid corrosion can be avoided, and the service life can be prolonged.

Description

technical field

[0001] The invention relates to the processing of electrical auxiliary materials, in particular to a processing method of shielding paper. Background technique

[0002] Shielding paper is usually used for shielding paper for transformers, etc., to shield voltage. The shielding paper in the prior art usually uses high-voltage insulating paper directly, resulting in poor shielding effect, and the aluminum foil is used between the papers. Paste with grease, which makes the insulating paper easy to be corroded by acid, and easy to oxidize, resulting in a short service life. Contents of the invention

[0003] Aiming at the defects and deficiencies of the prior art, the object of the present invention is to provide a method for processing shielding paper with good shielding effect and long service life.

[0004] In order to achieve the above object, the technical solution adopted in the present invention is: a processing method of shielding paper, the innovation...
