PUFFER-TYPE COMPRESSED-GAS CIRCUIT-INTERRUPTER |
摘要 |
<p>An improved puffer-type compressed-gas circuit interrupter includes a stationary tubular contact and a movable contact structure operably engageable with the stationary contact when the circuit interrupter is closed. A hollow nozzle directs a blast of compressed gas into the arc established between the stationary contact and the movable contact during opening. The nozzle in that interior thereof has a neck portion of predetermined diameter for directing the blast of compressed gas into the arc. The stationary contact has venting apertures therein of predetermined size and shape with at least a portion of the venting aperture means being within a predetermined section of the stationary contact. The stationary contact section has a length measured along the axis of that stationary contact equal to about three times the inside diameter of the stationary contact.</p> |
