Abstract: An operating modes selector is for an earthing switch that includes power contacts and a motor for moving the power contacts. The selector includes a plurality of positions corresponding respectively to various operating modes of the earthing switch, and includes cams whose positions are defined by the selector position. The selector contains a first cam which pulls a first locking organ designed to mechanically block the motor of the earthing switch when the selector is in a position corresponding to a locked closed mode wherein the earthing switch is closed.

Abstract: An electric cabinet that includes a front part and a rear part, and designed to receive removable electric functional units, further including: a separating partition delineating a first thermal area formed by a first space located at the front part of the electric cabinet, the first thermal area being designed to receive first electric apparatuses of the removable electric functional units, and a second thermal area formed by a second space located at the rear part of the cabinet, the second thermal area being designed to receive second electric apparatuses of the removable electric functional units, and the second thermal area is hotter than the first thermal area, and the first electric apparatuses heat more than the second electric apparatuses, the electric cabinet further includes a cooling source; and an actuator allowing air to flow.

Abstract: An electric cabinet comprising an outer frame defining the general shape of the electric cabinet and an inner frame comprising fixing uprights and cross-members, a functional assembly fixed onto the inner frame and comprising a plurality of functional units each equipped with a mounting plate designed to receive one or more electric equipment units. The mounting plates are fixed onto the uprights and fixing cross-members in contiguous manner to form a separating partition delineating a first space located towards the front part and a second space located towards the rear part. The functional assembly comprises at least one support fixed in independent manner onto an upright or a cross-member of the inner frame and a connector arranged on the support, the support being positioned on the upright or fixing cross-member so as to enable the connector to pass through an opening made through the mounting plate.

Abstract: A structure for supporting of an apparatus for electrical control or protection of a medium-voltage electrical cell, which structure has two sides substantially parallel to one another, each side having a main portion from which extends a wing, the wings connected at their free ends with two upper crossmembers connected to the main portion of the sides by the wings at their junctions with the main portions, and each having an opening to receive slidingly two of the upper crossmembers, and first abutment and locking means, to prevent movement of the crossmember relative to the structure in five of six degrees of freedom, displacement of the crossmember in translation in a direction opposite to the direction of insertion of the crossmembers being the sixth degree of freedom, installation of the crossmember in the openings without fastening means being sufficient to make the assembly stable.

Abstract: The invention relates to an electric cabinet (1) comprising a front part and a rear part and designed to receive electric functional units (2a), said electric cabinet (1) also comprising a separating partition (20) delineating: a first cold thermal area formed by a first space (E1) located at the front part of the cabinet, and a second hot thermal area formed by a second space (E2) located at the rear part of the cabinet. The electric cabinet (1) comprises a cooling and regulating device of the temperature of the first and second spaces E1, E2, said device comprising: a cooling source (100) positioned in contact with the first space (E1) to cool the latter; heat exchange means (40) enabling cold air to flow between the first space (E1) and the second space (E2).

Abstract: The invention relates to an electric cabinet comprising an outer frame defining the general shape of the electric cabinet and an inner frame comprising fixing uprights and cross-members, a functional assembly fixed onto the inner frame and comprising a plurality of functional units (20) each equipped with a mounting plate (200) designed to receive one or more electric equipment units, the mounting plates (200) being fixed onto said uprights and fixing cross-members in contiguous manner to form a separating partition (P) delineating a first space (E1) located towards the front part and a second space (E2) located towards the rear part, the functional assembly comprising at least one support (41) fixed in independent manner onto an upright or a cross-member of the inner frame and a connector (40) arranged on said support (41), said support being positioned on the upright or fixing cross-member so as to enable the connector (40) to pass through an opening (207) made through the mounting plate (200).
