Abstract

The invention discloses an anti-aging sealing gasket for a transformer and relates to the field of transformers' components. The invention aims to solve the problem that a sealing gasket used inside an existing transformer is easy to age. The anti-aging sealing gasket for a transformer comprises the following ingredients (by weight): 15-40 parts of polyvinyl alcohol, 15-35 parts of acrylic resin, 4-15 parts of lignocellulose, 5-16 parts of silica, 0.5-2 parts of an anti-oxidant and 0.5-2 parts of hydroxyethyl cellulose. The anti-aging sealing gasket for a transformer contains the antioxidant ingredient and then has a good antioxidant effect. Thus, service life of the sealing gasket can be prolonged. In addition, the ingredients of the sealing gasket are safe and nontoxic ingredients and are safe to the environment.

Description

technical field [0001] The invention relates to the field of transformer components, in particular to a transformer anti-aging sealing rubber pad. Background technique [0002] Transformer is one of the more important equipment in the power industry. It is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. Existing transformer boxes are mostly made of metal, which can prevent external factors from damaging the transformer due to the high mechanical strength of the metal. A lot of sealing materials are used in transformers. Once the use time reaches a certain number of years, it is often prone to oxidation, and the rubber pad is sticky, which cannot play a good sealing role. Contents of the invention [0003] In order to solve the above problems, the present invention provides a transformer anti-aging sealing gasket with long service life. [0004] The transformer anti-agi...
