Abstract

The invention relates to a transformer sealing ring with high wear resistance for electrical use. The sealing ring comprises raw material components in parts by weight as follows: 40-60 parts of styrene-butadiene Rubber, 20-40 parts of chloroprene rubber, 23-26 parts of fluoroether rubber, 0.1-15 parts of graphene, 13-15 parts of phenol formaldehyde resin, 1-10 parts of a silane coupling agent, 12-15 parts of semi-reinforcing furnace black, 10-12 parts of calcined clay, 1-2 parts of magnesium chloride, 1-5 parts of magnesium powder, 5-7 parts of nano-MoS2, 1-10 parts of an anti-aging agent, 0-20 parts of a plasticizer and 1-5 parts of an accelerator. The sealing ring has excellent performance including corrosion resistance, high-temperature resistance, wear resistance, tear resistance and stretching resistance, is long in service life and guarantees the sealing performance between a transformer oil tank and a transformer cover as well as between a casing and the transformer cover.

Description

technical field [0001] The invention relates to a high wear-resistant transformer sealing ring for electric power, which belongs to the technical field of electric power equipment. Background technique [0002] Since transformer oil is usually used in the transformer to cool down the temperature of the transformer, the seal between the transformer oil tank and the casing and the transformer cover is very important. Traditional transformer annular rubber seals usually use a strip-shaped sealing rubber row to connect the two The quality of the rubber row and the sealing quality of the rubber row interface directly affect the sealing performance of the transformer. Due to the particularity of the location of the sealing ring, it is subject to long-term pressure and fractures, and is susceptible to high temperature and corrosion of the transformer oil. The service life of ordinary rubber sealing tape is short, and it is difficult to meet the long-term operation of the transforme...
