The frictional resistance of a certain type of SF6 high voltage circuit breaker’s arc extinguishing chamber were calculated and measured. The factor influencing the frictional resistance were analyzed and identified. It was found that the factors also exert significant effects on the mechanical work of the circuit breaker. By improving the factor the mechanical work was reduced
which indicates that control of the frictional resistance of arc extinguishing chamber during the product assembly process can effectively improve the product assembly quality and prolong the product life.
