    摘要： A slideably mounted insulating shield is positioned over the terminals of a secondary disconnect attached to the side wall of a circuit breaker compartment. Inserting the circuit breaker into the compartment brings the secondary disconnect terminals on the breaker into engagement with the secondary disconnect terminals in the compartment by displacing the insulating shield. Removal of the breaker from the compartment forces the insulating shield to return to position over the compartment secondary disconnect terminals thereby isolating the disconnect terminals from inadvertent contact with an operator.

    摘要： Draw-out circuit breaker apparatus is taught with an interphase barrier for metal enclosed switchgear. The interphase barrier includes a unitary member which is mounted on wheels so that it may be partially withdrawn when the circuit interrupter draw-out element is withdrawn thus allowing pivotal shutter members to be moved into position in front of the spouts or bottles of the high voltage terminals of the metal enclosed system. When the movable draw-out element is reinserted in its fully connected position the barrier moves flush with the previously described spouts as the shutters rotate upwardly and downwardly to accommodate insertion of the terminals of the movable circuit breaker into the complementary stationary high voltage terminals.

    摘要： A shutter for high voltage metal clad switchgear is taught which is a composite of electrically insulating material such as polyester and islands of electrically conductive material such as non-magnetic aluminum. The polyester material reduces the chance for flash-over between the high voltage conductors and the grounded metal islands or other conductors, while the grounded metal islands provide a region of zero ground potential in an area associated with the opening in high voltage terminal assemblies to thus assure that personnel who approach this region will always be exposed to ground potential and not high voltage potential.

    摘要： An improved shutter for closing off the holes in an insulated partition between a circuit breaker space and a bus bar space when the circuit breaker is removed in which spherical members, each attached to one end of a respective rope which has its other end let through a small hole above the hole to be covered and held in place by a knob on its other end, are suspended by the ropes to lie against and cover the holes.
