Abstract: Disclosed are example embodiments of a dead tank circuit breaker for protecting electrical components against electrical surges and other voltage anomalies such as transient overvoltages. The circuit breaker includes: one or more vacuum interrupters; a current bypass circuit electrically coupled to the one or more vacuum interrupters; a dead tank encasing and hermetically sealing the one or more vacuum interrupters and the current bypass circuit, wherein the dead tank is pressurized with a non-SF6 gas; and a controllable mechanism coupled to the one or more vacuum interrupters and to the current bypass circuit. The controllable mechanism is configured to actuate the one or more vacuum interrupters and the current bypass circuit to open or close a main circuit path such that any pre-strike arcing occurs on the current bypass circuit instead of the one or more vacuum interrupters.

Abstract: End cap section (10) for use in the construction of a configurable pressure vessel (80) and the vessel constructed thereof. The vessel having an interior volume and including at least one such end cap section joined to a second section. The end cap section (10) has a tubular wall (12) extending from an enclosed first end (16) to an open second end (18). At least one mounting pad (30) is positioned on the outer surface (20) of the wall on the enclosed first end (16) thereof. Such mounting pad has a base portion (32a-e) supported on the wall (12) and a generally tubular stub portion (34a-e) extending outwardly from the base portion intermediate a proximal end adjoining the wall (12) and a distal end (40a-e) configurable for connection to a fluid component (90). With the stub proximal end being closed by the wall, such end is openable through the wall to provide a port opening into the interior volume of the vessel.
