An improved high-voltage circuit-interrupter of the gas-blast type is provided having improved gas-partitioning and particle-collecting means so provided as to prevent the entrance of small insulating, or metallic particles into the high-pressure storage chamber of the interrupter. A non-perforated insulating support member provides support for the high-voltage conductor, and, additionally, seals off the high-pressure gaseous storage region within the high-pressure chamber from the contact interrupting chamber, where, due to contact engagement and disengagement, relatively small metallic particles may be generated, and if allowed to wander into the high-pressure storage chamber provided between the high-voltage conductor and the outer grounded tube of the high-pressure storage chamber, would precipitate, or encourage high-voltage breakdown, or flashover between these two conducting members which are at widely-different voltages, say, for example, 200 K. V. Another important aspect of the invention includes the provision of a grounded collecting chamber located at a strategic position to collect the insulating, or metallic particles, generated within the contact-interrupting region, in an electrically field-free space, where they are permanently collected, and may be removed periodically, if desired, as a part of the maintenance schedule for the circuit-interrupter. However, in the collecting region they are trapped, and are not permitted to advance or enter into the high-pressure chamber.
