Abstract

A display unit and an installation are disclosed for distributing electrical energy. In an embodiment, a display unit includes a plurality of switches. The display unit is connected via a communication link to the switches and is configured to receive data relating to the operation of the switches. Each switch of the installation comprises two mechanically disconnectable switching elements, a sensor unit to detect the current flowing over the switching elements, an electronic trip unit to initiate the disconnection of the switching elements if a trip condition allocated to the switch is fulfilled, and a mechanical switching unit to disconnect the switching elements if the trip condition is fulfilled.

Claims

1. A display unit comprising:

a plurality of switches, the display unit being connected via a communication link to the switches and is configured to receive and display data relating to the operation of the switches.

2. The display unit of claim 1, wherein data of all switches is displayed.

3. The display unit of claim 1, further comprising:

a display, to display the data.

4. The display unit of claim 1, wherein the communication connections are designed as bus connections.

5. The display unit of claim 1, wherein the display unit is connected via a communication link via a data server to the switches and the data server is configured to transmit and receive the data.

6. The display unit of claim 5, wherein the display unit, together with the data server, form a display/data unit.

7. The display unit of claim 1, wherein the display is adapted automatically to the number of switches.

8. The display unit of claim 1, wherein the data are displayed in prioritized form.

10. The display unit of claim 2, further comprising:

a display, to display the data.

11. The display unit of claim 2, wherein the communication connections are designed as bus connections.

12. The display unit of claim 2, wherein the display unit is connected via a communication link via a data server to the switches and the data server is configured to transmit and receive the data.

13. The display unit of claim 12, wherein the display unit, together with the data server, form a display/data unit.

14. The display unit of claim 2, wherein the display is adapted automatically to the number of switches.

15. The display unit of claim 2, wherein the data are displayed in prioritized form.

9. A switching installation for distributing electrical energy among a plurality of installation branches via switches, comprising:

a data server, connected via a communication link to the switches, to receive data relating to the operation of the switches; and

a display unit, connected via a communication link to the data server, to display the data of the switches, wherein each switch comprises;

at least two mechanically disconnectable switching elements,

a sensor unit to detect a current flowing over the switching elements,

an electronic trip unit to initiate the disconnection of the switching elements if a trip condition allocated to the switch is fulfilled, and

a mechanical switching unit to disconnect the switching elements if the trip condition is fulfilled.
