Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

(1) For better explanation of the invention,

(2) FIG. 1 shows an operating component according to the invention, and

(3) FIG. 2 shows an arrangement comprising a plurality of operating components.

DESCRIPTION OF THE INVENTION

(4) FIG. 1 shows an operating means 1 according to the invention. The operating means 1 comprises an electrical switchgear 6 having a motor control 7. The electrical switchgear 6 is monitored by a sensor device 2. The sensor device 2 records measurement values, for example a temperature in the switchgear 6, number of switching actions and opening times of the power switch. The measurement values collected are archived in a data memory 4, which is configured as a conventional hard drive. The data memory records the entire measurement value history of the operating means in the manner of a flight recorder, so that this can be used for more extensive analyses.

(5) The measurement values are evaluated in a status estimation device 5, which is part of the motor control 7. The status estimation device 5 may, for example, be provided as a software component inside the motor control. With the aid of the measurement values recorded, the status estimation device 5 determines the operating status of the electrical switchgear 5. On the basis of this, a status report 20 is generated, which may be sent by means of a communication device 3, for example via a radio link. The status report 20 contains at least one information item about the current operating status, i.e. for example in the simplest case a binary signal. In this case, the status report contains, for example, the value 0 for operationally ready and 1 for maintenance required. The status report either may be sent only in the event of a fault, or periodic transmission of the operating status may be carried out. Periodic transmission, i.e. for example with one status report per day, has the advantage that an operator always receives positive information about operational readiness of their operating means.

(6) A position detection device 8 is furthermore provided, which may establish the current position of the operating means 1 by means of GPS information, which is received from a satellite 21. The status report 20 may then respectively be supplemented with position information, so that the position of the operating means 1 is also transmitted.

(7) Furthermore, the status report 20 may contain further details about the operating status or individual measurement values. A prediction of the operating status to be expected may furthermore be determined by means of the status estimation device and sent via the communication device 3. It is furthermore advantageous for identification of the operating means also to be inserted into the report 20 by means of the status estimation device 5, i.e. for example serial number, manufacturer and type of the operating means. A unique number is also conceivable and advantageous, for example a media access control (MAC) address, which has already been provided manufacturer-independently ex factory to all operating means. As an alternative, an IP address may also be used, although this needs to be adapted to the consumer network in order to allow unique allocation.

(8) The operating means 1 shown comprises a further module 9, which is connected to a further sensor device 10 and a further data memory 11. This module 9 is therefore monitored separately, the evaluation of the measurement values of the module 9 also being carried out by the status estimation device 5. The latter may either determine an overall operating status or provide and transmit two different operating statuses for the electrical switchgear 6 and the further module 9.

(9) It is a significant advantage of the present operating means that the intelligence, already present in the scope of the motor control 7, of an operating means is used in order to carry out autonomous status monitoring in situ. The need to transmit all measurement values to a central evaluation device, such as a monitoring system, and to analyze them there is avoided. Each operating means of this design can monitor itself and send a simple maintenance signal to the operator of the operating means or a maintenance service provider, if so required. The need to provide elaborate condition monitoring systems and correspondingly trained personnel is avoided, because each operating means is already provided with its own fully integrated status monitoring by the manufacturer.

(10) FIG. 2 shows an arrangement having three high-voltage masts 12 and overhead lines 13, which connect two switch groups 14 and 16 to one another. The two switch groups 14, 16 respectively comprise a transformer 15 and an operating means 1 according to the invention with a communication device 3. In this embodiment, the operating means are configured to receive status reports of further operating means via their communication devices 3 and to forward these to a central evaluation device 17 at the premises of the operator or maintenance service provider. In the example shown, the central evaluation device 17 receives a status report of the switch group 14, which has been forwarded via the switch group 16. The status report contains a maintenance request, so that the central evaluation device 17 can send a maintenance team 18 to the switch group 14.
