【Abstract】 For the present situation, the opening velocity characteristic of high voltage circuit breaker is not adjustable. A new method of adjusting the opening velocity characteristic is put forward, that is adding electromagnetic on off valves to the hydraulic mechanism of the circuit breaker and applying discontinuous flow rate to adjust the opening velocity. With this method the need of adjustment by grades to opening velocity of high voltage intelligent operation circuit breaker can be met.更多还原
