Abstract
A power shut-off module includes an insulating housing, two pairs of fixed contacts and two movable contacts rigidly attached to an item of movable equipment that is movable in translation in the housing between an open position and a closed position. The module includes an insulating shield device having a fixed end rigidly attached to the housing and a movable end rigidly attached to the item of movable equipment, and which has a length that is variable between an extended position when the item of movable equipment is in the open position and a retracted position when the item of movable equipment is in the closed position, in order to create a dielectric barrier between the fixed contacts of one and the same pair of fixed contacts.
Claims8
An electrical shut-off module comprising an electrically insulating housing, at least one pair of fixed contacts, including an upstream fixed contact and a downstream fixed contact, and at least one movable contact secured to movable equipment which is movable in translation in said housing with respect to said at least one pair of fixed contacts between an open position and a closed position, wherein the shut-off module comprises an electrically insulating shield device disposed in said housing between the upstream fixed contact and the downstream fixed contact of said at least one pair of fixed contacts, said shield device comprising a fixed end secured to said housing and a movable end secured to said movable equipment and having a length that is variable between an extended position when said movable equipment is in the open position and a retracted position when said movable equipment is in the closed position in order to produce a dielectric barrier between the upstream fixed contact and the downstream fixed contact of said at least one pair of fixed contacts.
