In order to improve the arc medium recovery speed of circuit breaker,a novel chamber structure with rotary-gas grooves in nozzle was presented for 500 kV SF6 circuit breaker with one-break.
为了提高断路器的弧后介质恢复速度,笔者以500 kV单断口高压SF6断路器为研究对象,提出了在气体通道的上游增加旋气槽的设想,将传统的轴向吹弧改进为旋转吹弧。
A fixed-geometry two-dimensional mixed-compression supersonic inlet with sweep-forward high-light and bleed slot in an inverted "X"-form layout was tested in a wind tunnel.
针对一种带放气槽的定几何二元倒置"X"型混压式超音速进气道进行了风洞吹风实验。
