Abstract

A remote service system for a circuit breaker fixed in a remote allocation. Remote service is provided by any station that can be accessed through a communication network. The system is provided, on one side, with a diagnostic hand-held apparatus which is dedicated to a switch service and should be connected, if necessary, to a circuit breaker, through a connecting unit provided to that end, and on the other side, with a telecommunication interface for exchanging a data through a telecommunication network.

Claims

1. A system for remote servicing of a circuit breaker, comprising:

a diagnosis handset, connectable to the circuit breaker, wherein the diagnosis handset includes on one side, a plug-in unit for connection to the circuit breaker, and includes on another side, a communications interface which allows data to be interchanged with a plurality of service centers, without interrupting commands from a control center, and wherein the circuit breaker includes a plug socket to which the diagnosis handset is connectable via its plug-in unit.

2. The system as claimed in claim 1, wherein the communications interface comprises a telecommunications unit.

3. The system as claimed in claim 2, wherein the telecommunications unit includes a TAE socket and a TAE plug.

4. The system as claimed in claim 2, wherein a device, which in response to a telephone call, sets up a data connection to one or more of the service centers, is integrated in the diagnosis handset.

5. The system as claimed in claim 2, wherein a dialing device which, on command by a user, produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

6. The system as claimed in claim 2, wherein a dialing device, which automatically produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

7. The system as claimed in claim 1, wherein the communications interface comprises a Western modular connection unit.

8. The system as claimed in claim 7, wherein a device, which in response to a telephone call, sets up a data connection to one or more of the service centers, is integrated in the diagnosis handset.

9. The system as claimed in claim 7, wherein a dialing device which, on command by a user, produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

10. The system as claimed in claim 7, wherein a dialing device, which automatically produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

11. The system as claimed in claim 1, wherein the communications interface comprises a plug-in unit, as is used for networking of computers in buildings.

12. The system as claimed in claim 11, wherein a device, which in response to a telephone call, sets up a data connection to one or more of the service centers, is integrated in the diagnosis handset.

13. The system as claimed in claim 11, wherein a dialing device which, on command by a user, produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

14. The system as claimed in claim 11, wherein a dialing device, which automatically produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

15. The system as claimed in claim 1, wherein a device, which in response to a telephone call, sets up a data connection to one or more of the service centers, is integrated in the diagnosis handset.

16. The system as claimed in claim 1, wherein a dialing device which, on command by a user, produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

17. The system as claimed in claim 1, wherein a dialing device, which automatically produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

18. The system as claimed in claim 1, wherein the system is for the transmission of up-to-date information about the state of a circuit breaker, installed at a remote location, to one or more of the service centers, wherein the transmission occurs by at least one of a telecommunications network and by radio.

19. A diagnosis handset, connectable to a circuit breaker, for use in a system for remote servicing of the circuit breaker, comprising:

a plug-in unit, on one side of the diagnosis handset, for connection to the circuit breaker; and

a communications interface, on another side of the diagnosis handset, which allows data to be interchanged with a plurality of service centers without interrupting commands from a control center, wherein the circuit breaker includes a plug socket to which the diagnosis handset is connectable via its plug-in unit.

20. The diagnosis handset as claimed in claim 19, wherein a device, which in response to a telephone call, sets up a data connection to one or more of the service centers, is integrated in the diagnosis handset.

21. The diagnosis handset as claimed in claim 19, wherein a dialing device which, on command by a user, produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

22. The diagnosis handset as claimed in claim 19, wherein a dialing device, which automatically produces a data connection to one or more of the service centers, is integrated in the diagnosis handset.

23. A system for remote servicing of a circuit breaker, comprising:

a diagnosis handset, connectable to the circuit breaker, wherein the diagnosis handset includes on one side, connection means for connecting the handset to the circuit breaker, and includes on another side, communications interface means for allowing data to be interchanged with a plurality of service centers without interrupting commands from a control center, and wherein the circuit breaker includes a plug socket to which the diagnosis handset is connectable via the connection means.

24. The system as in claim 23 further comprising:

means, integrated in the handset and responsive to a telephone call, for setting up a data connection to one or more of the service centers.

25. The system as in claim 23 further comprising:

means, integrated in the handset and responsive to a command by a user, for producing a data connection to one or more of the service centers.

26. The system as in claim 23 further comprising:

means, integrated in the handset, for automatically producing a data connection to one or more of the service centers.

27. A diagnosis handset, connectable to a circuit breaker, for use in a system for remote servicing of the circuit breaker, comprising:

connection means, on one side of the diagnosis handset, for connecting the handset to the circuit breaker; and

communications interface means, on another side of the diagnosis handset, for allowing data to be interchanged with a plurality of service centers without interrupting commands from a control center, wherein the circuit breaker includes a plug socket to which the diagnosis handset is connectable via the connection means.

28. The diagnosis handset as claimed in claim 27 further comprising:

means, integrated in the handset and responsive to a telephone call, for setting up a data connection to one or more of the service centers.

29. The diagnosis handset as claimed in claim 27, further comprising:

means, integrated in the diagnosis handset and responsive to a command by a user, for producing a data connection to the one or more service centers.
