Flexible dielectric material for high voltage switch

摘要

An electrical switch includes a tubular housing having a conductor receiving end and an operating end opposite the conductor receiving end. The tubular housing also includes a conductive interface positioned intermediate the conductor receiving end and the operating end. An operating rod extends through the operating end toward the conductor receiving end. The operating rod is moveable between a first position to engage the electrical switch and a second position to disengage the electrical switch. A gelatinous dielectric material is provided within a portion of the tubular housing, and around the operating rod, in the operating end to prevent voltage from the conductive interface from arcing to the operating end. The gelatinous dielectric material is configured to deform to maintain contact with the operating rod in the first position and the second position.

1. An electrical switch, comprising:
a tubular housing having a conductor receiving end and an operating end opposite the conductor receiving end, wherein the tubular housing includes a conductive buttress positioned intermediate the conductor receiving end and the operating end; an operating rod extending through the operating end toward the conductor receiving end, wherein the operating rod is moveable between a first position to engage the electrical switch and a second position to disengage the electrical switch; a gelatinous silicone material contained within a portion of the tubular housing, and around the operating rod, in the operating end to prevent voltage from the conductive buttress from arcing to the operating end, wherein the gelatinous silicone material is configured to deform to maintain contact with the operating rod in the first position and the second position; and a flexible partition located between the gelatinous silicone material and the conductive buttress, wherein the flexible partition includes a bore therethrough for receiving the operating rod, and wherein the flexible partition separates the gelatinous silicone material from the conductive buttress.
