<p>SELF-FLOW GENERATING GAS INTERRUPTER of the Invention A unique self-flow generating gas interrupter of the type wherein arc-extinction is performed by the creation of a negative pressure region brought about by the separation of the interrupter contacts. The interrupter incorporates a novel arrangement of valves so as to optimize the performance of the interrupter over the broad range of interrupting currents. In one embodiment a check valve is used to supply gas from the exterior of the interrupter casing and into the arcing chamber in response to the pressure within the arcing chamber decreasing or falling below a pre-selected value. In this manner, less force is required to operate the interrupter when lowcurrents are encountered. In another embodiment a relief valve is used to release the pressure developed in the arcing chamber in the event that a large interrupting current is encountered. Still another embodiment incorporates both the check valve and the relief valve.</p> |
