Abstract

An electrical device for supplying electrical power to multiple power units includes a first module, including an electrical circuit breaker; a second, removable module, including a control circuit, programmed to trip the circuit breaker depending on values of the electric current that is flowing through power lines; a connection interface provided with output connectors that are connected to the power lines; removable elements, each containing an item of electrical equipment that is intended to be connected to an electrical power unit and to one of the power lines by the output connectors, the control circuit being connected to an interface for controlling each removable element via a data link by virtue of the connection interface.

First claim

The invention claimed is:

1. An electrical device for supplying electrical power to multiple power units, comprising:
a fixed support;
input terminals for receiving a polyphase electric current;
a first module comprising a first power line connected to the input terminals, said power line comprising an electrical circuit breaker;
a second removable module comprising:
second power lines connected to the first power line via an electrical distribution circuit configured to distribute the polyphase electric current from the first power line to each of the second power lines;
a control circuit programmed to trip the circuit breaker depending on values of the electric current that is flowing through the second power lines;
a connection interface provided with output connectors connected to the second power lines;
removable elements each containing an item of electrical equipment intended to be connected to an electrical power unit via output terminals of said removable elements,
each removable element being movable between an assembled position, in which each removable element is connected to the connection interface, and a removed position, in which each removable element is removed from the connection interface,
the electrical equipment being connected to one of the second power lines via the output connectors of the connection interface when the removable element is in the assembled position,
the control circuit being connected to a control interface of the electrical equipment of each removable element via a data link by virtue of the connection interface in order to send a control signal to said electrical equipment.

2. The device according to claim 1 , wherein the electrical equipment is a contactor with separable contacts adapted to selectively interrupt the flow of an electric current on the second power line to which it is connected.

3. The device according to claim 2 , wherein the first module comprises an additional contactor connected to the first power line and adapted to be controlled by the control circuit.

4. The device according to claim 1 , wherein the connection interface comprises housings each intended to receive a connection portion of one of the removable elements when said removable element is in the assembled position.

5. The device according to claim 1 , wherein the second module is connected to a data bus and wherein the control circuit is programmed to send a control signal depending on control orders received from the data bus.

6. The device according to claim 1 , wherein each removable element comprises a data input terminal for receiving a control order, said data input terminal being connected to a first link part, and in that the second module comprises a second link part connected to the control unit.

7. The device according to claim 1 , wherein the connection portion of each removable element comprises connectors, the shape of which matches that of the output connectors and which are formed so as to project relative to the connection portion, the electrical connection between the electrical equipment and the corresponding second power unit being provided via said connectors.

8. The device according to claim 1 , wherein the connection interface and the connection portion of each removable element comprises translation movement guidance devices with matching shapes in relation to each other in order to enable a translation movement of said removable element relative to the second module.

9. The device according to claim 1 , wherein the electrical equipment is a direction or rotation inverter or a data input/output module.

10. The device according to claim 1 , wherein the first module is removable.
