Abstract

The invention teaches the use of a shock-resisting non-gas-absorptive plate of insulating material mounted on the internal tank walls of an oil circuit-breaker, and centered on the current-interrupter vents. Resilient rubber insulators are used in resiliently mounting the shock-resisting plate to absorb the shock forces exerted by the ionized gas products striking the shield. The insulating barrier is permitted to resiliently move to accommodate short-duration pressure differences on the front and rear faces thereof, thus avoiding damaging deflections of the plate.
