Analysis Of The Mechanism Of Gas Corrosion Of Metal Components In The Operating Mechanism Of Sf6 Circuit Breaker

As the gas continues to circulate and an electric arc is generated, the gas produced by sf6 circuit breaker operating mechanism reacts with the metal surface, gradually forming corrosive substances, leading to oxidation, wear, and embrittlement of the metal parts. Especially under the instantaneous impact of high-voltage current, the corrosion process is accelerated when impurities and moisture in the gas of sf6 circuit breaker spring mechanism come into contact with the metal, further reducing the mechanical strength and electrical conductivity of the metal.
