摘要:
Hinge assembly for a cabinet housing of switchgear panel, comprising: plate means supporting pivot means for enabling rotation of door means of the cabinet housing about a pivotal axis between an open position and a closed position; locking protrusion means and locking seat means provided on said plate means and configured for internally receiving said locking protrusion means so as to lock said door means in said closed position.
摘要:
Protection filter assembly (1) for a switchgear panel (2), comprising: an enclosure (5) defining an evacuating path for conveying out of the switchgear panel a flow of flames, gases, particulates which may originate in case of explosions or electric arcing events occurring inside the switchgear panel. Mitigating barrier elements (12) are provided for mitigating the intensity of the flow which barriers are distributed along the evacuating path so as to define a plurality of expansion chambers for progressively expanding the flow along the evacuating path itself.
摘要:
A fastening and separating assembly (1) for a cabinet housing of a switchgear panel, comprising first baffle means (15) and second baffle means (16) interposable between a first zone (5) and a second zone (6) of the cabinet housing; the first baffle means and the second baffle means are operatively connected to each other so as to mutually cooperate for clamping there between a separating element (10) which is intended to separate the first zone from the second zone and through which one or more electrical cables, extending from the first zone to the second zone are threaded. The first baffle means and the second baffle means are configured to be connected to the cabinet housing so as to firmly keep in a set position, and prevent any displacement of the separating element and the one or more electrical cables.

An interlocking device (1) suitable for a switchgear having a first compartment (3) provided with a first closing element (5), and a second compartment (4) provided with a second closing element (6), comprises: -obstruction-locking means (13) configured for preventing said first closing element (5) from closing said first compartment (3) if said second closing element (6) is not in a closing position in which access to said second compartment (4) is hindered, and - block-locking means (14, 18, 22) operatively connected to said obstruction-locking means (13) and configured for blocking said second closing element (6) in said closing position if said first closing element (5) is in a respective closing position in which access to said first compartment (3) is hindered.
摘要:
Connector element (1) for a switchgear apparatus (2), comprising an electrically conducting body (3) extending along a longitudinal axis (X) and provided with a first portion (17) suitable for electrically engaging with a movable electrical connector (5a) and having a first cross-section (C1), and a second portion (18) extending from said first portion (17) to a fixing end (12) of the electrically conducting body (3). T second portion (18) has a second cross-section (C2) which is greater than the first cross-section (C1) for acting as a heat-dissipating portion. The electrically conducting body further comprises a through-opening (20) which extends parallel to the longitudinal axis (X) through the first and second portions (17, 18), and is suitable for housing a fixing element (21) thus enabling the electrically conducting body (3) to be directly fixed, through said fixing end (12), to an electrical transformer (10) of the switchgear apparatus (2).
摘要:
An interlocking device suitable for a door (4) of a switchgear (2) having a draw-out circuit breaker (3), comprises: — a locking unit (30) movable between a locking position and an unlocking-position for preventing and allowing opening of the door (4) respectively, — a driving unit (40) arranged for acting on the locking unit (30) upon a movement of the draw-out circuit breaker (3),
the driving unit (40) being configured for placing the locking unit (30) in the unlocking-position when the draw-out circuit breaker (30) is in an extracted-non-operative-position, and for enabling positioning of the locking unit (30) in the locking position upon a movement of the draw-out circuit breaker (3) from the extracted-non-operative-position towards an inserted-operative-position.
