<p>An improved, multi-function, stationary-contact-and-voltage-shield structure is provided for a high-voltage gas-puffer-type circuit-interrupter, in which the surrounding metallic shield provides a smooth, low-gradient voltage shape, collecting and cooling the dispersed hot arced gases, generated during the interrupting operation at the arc, by the provision of selectively-located venting cooling port holes provided in the metallic shield structure and also in the stationary contact structure. The arrangement of the enveloped stationary contact and surrounding main stationary contact fingers, together with the outer, encompassing vented metallic shield arrangement is such as to provide an improved highly-effi-cient single-pressure puffer-type high-voltage circuitinterrupter.</p> |
