The Impact Of Voltage Level On The Operating Mechanism Of Sf6 Circuit Breakers

In high-voltage and ultra-high-voltage applications, sf6 circuit breaker operating mechanism needs to be matched with higher insulation strength and greater kinetic energy reserve in order to meet the requirements of quickly cutting off high-voltage current. The increase in voltage changes the formation and extinction conditions of the arc inside the circuit breaker, thereby affecting the design parameters of the sf6 circuit breaker spring mechanism circuit breaker, such as spring stiffness, transmission ratio, and switch gap setting.
