Abstract

A disconnecting electrical apparatus includes a disconnecting block, including elements for disconnecting an electric current each able to be actuated with a coupling member, to switch this disconnecting element to a blocking state or a state allowing the electric current to pass, an actuator block, provided with a controllable electromagnet suitable for generating an electromagnetic force, a mobile container provided with a magnetic plate, which displaces the coupling members, under the effect of the electromagnetic force, so as to switch the disconnecting elements. The apparatus also includes a connection interface inserted between the disconnecting block and the actuator block, the mobile container being housed inside the connection interface.

First claim

1 . An electrical apparatus for disconnecting an electric current, including comprising:
a disconnecting block, including elements for disconnecting an electric current, each able to be actuated by of a coupling member, to switch this said disconnecting element to a blocking state or a state allowing the electric current to pass; an actuator block, provided with a controllable electromagnet suitable for generating an electromagnetic force in response to a control signal; a mobile container provided with a magnetic plate, said mobile container being suitable for exerting, under the effect of the electromagnetic force, a mechanical force that displaces the coupling members so as to switch the disconnecting elements; a connection interface, distinct from the disconnecting block and the actuator block, said connection interface being inserted between the disconnecting block and the actuator block, the mobile container being housed inside the connection interface.

2 . The apparatus according to claim 1 , wherein the connection interface includes a main body provided with a guiding device for translatably guiding the container with respect to the main body.

3 . The apparatus according to claim 2 , wherein the guiding device includes a lever that mechanically connects the mobile container to the main body.

4 . The apparatus according to claim 1 , wherein the connection interface is fastened to the disconnecting block by of a fastening system of mortise-and-tenon type, either the disconnecting block or the connection interface including a tenon, the other including a groove that is complementary in shape to the tenon.

5 . The apparatus according to claim 1 , wherein the width of the mobile container is greater than the distance between the coupling members that are located on opposite sides of the front face of the disconnecting block.

6 . The apparatus according to claim 1 , wherein the mobile container is provided with a zone for receiving the coupling members for the purpose of anchoring the mobile container so that it is translatably rigidly connected to the respective mobile portions of the disconnecting elements bearing the coupling members, the mobile container being sized so as to exert a force simultaneously on all of the coupling members when it is displaced under the effect of the electromagnetic force.

7 . The apparatus according to claim 6 , wherein the coupling members include screws, a head of which protrudes with respect to the disconnecting element, the mobile container being provided with forks that are each intended to grip a corresponding screw head for the purpose of anchoring the mobile container to the mobile portions.

8 . The apparatus according to claim 1 , wherein the switching of each of the disconnecting elements is achieved by displacing the coupling member in a direction parallel to the direction of translation of the mobile container.

9 . The apparatus according to claim 1 , wherein the disconnecting block includes three disconnecting elements.

10 . The apparatus according to claim 1 , wherein the disconnecting block includes four disconnecting elements.
