摘要
针对现用高压断路器分闸速度无法有效调节的现状 ,提出了在断路器液压机构中加装电磁开关阀 ,采用不连续的流量控制以实现速度的调节。该方法可以满足高压智能操作断路器分闸速度分级调节的需要。
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.
