Definitions
- the present invention relates to a method and a device for fire prevention in electrical devices, in particular apparatus and installations.
- Fire prevention There are three main stages in fire protection: Fire prevention, fire detection and fire fighting.
- the method according to the invention is characterized in that the time course of the Power consumption of the facility in question is monitored and for the occurrence of an abnormal Operating condition is examined.
- a first preferred embodiment of the method according to the invention is characterized in that that the time course of power consumption is measured and by means of intelligent Signal processing algorithms detected the occurrence of an abnormal operating condition and that when an abnormal operating condition occurs, the electrical device is switched off and / or alarm is triggered.
- a third preferred embodiment of the method according to the invention is characterized in that that a range of normal operating conditions is defined in a learning process and that the occurrence of an abnormal operating condition based on a comparison of the time course of the power consumption is determined with this area.
- the named learning process is preferably a supported learning process, which in one optionally switchable learning mode takes place, or an independent learning process, in which the range of normal operating states is automatically determined.
- the invention further relates to a device for performing the above method.
- the device according to the invention is characterized by means for measuring the temporal History of the power consumption of the electrical device in question and for comparison the measured power consumption with a normal operating state Setpoint.
- a first preferred embodiment of the device according to the invention is characterized in that that the means mentioned with the power supply of the electrical device connected and to interrupt the power supply when an abnormal operating condition occurs are trained.
- a second preferred embodiment of the device according to the invention is characterized in that that the means mentioned are connected to a hazard alarm center, by which an alarm is triggered when an abnormal operating state occurs and / or the relevant electrical device is switched off.
- a third preferred embodiment is characterized in that the means mentioned are connected to a fire alarm system via which the Occurrence of an abnormal operating condition the sensitivity of the area in question electrical device arranged fire detector is increased.
- an electrical device 1 is connected to a power supply via a line 2 3, for example connected to the mains.
- the electrical device 1 can a single electrical apparatus, an electrical machine, or one of a plurality of Apparatus and / or machines existing system.
- the device 1 is a sensor 4 for the monitoring of the time profile of the power consumption of the device 1 is assigned.
- the sensor 4 measures the time course of the power consumption and uses intelligent Signal processing algorithms the occurrence of an abnormal operating condition, i.e. a a certain degree of deviation from the normal operating condition. At the If an abnormal operating state occurs, suitable measures, such as switching off the electrical device and / or triggering an alarm.
- the normal operating state in a learning process is the normal operating state not fixed unchangeably, but is determined by measuring the deviations, that are within certain limits, either in a supported or in a independent learning process, adaptively updated. In this way, the sensor 4 "learns" independently know the area of the normal operating state and can deviate from the normal Operating status via an alarm output 5 Trigger alarm.
- the senor 4 is connected to the electrical device 1 in question Stand alone device, whose alarm output 5 is connected to the feed line 2 and in the event of an alarm, i.e. when an abnormal operating state occurs, by opening a Switch 7 separates.
- alarm output 5 can be designed as a relay output.
- an alarm is triggered and / or the relevant electrical device 1 off. If the hazard alarm center 6 is a fire alarm center, then additionally From danger level 1, the sensitivity of those connected to the fire alarm control panel Fire detector 8 in the hazardous area, that is the area in the vicinity of the electrical Device 1, can be increased.

Abstract
Description
- Der normale Betriebszustand ist durch die bekannten Spezifikationen der betreffenden elektrischen Einrichtung 1 definiert. Jede einen vorgegebenen Bereich übersteigende Abweichung von den Spezifikationen stellt einen abnormalen Betriebszustand dar.
- Der normale Betriebszustand wird in einem unterstützten Lernprozess definiert. Dabei bedeutet unterstützt, dass die erfindungsgemässe Vorrichtung in einen Lernmodus geschaltet wird und in diesem die Leistungsparameter misst. Dann wird die Vorrichtung scharf geschaltet, wobei die im Lernmodus gemessenen Leistungsparameter den normalen Betriebszustand definieren.
- Der normale Betriebszustand wird in einem selbständigen Lernprozess automatisch festgelegt. Die Vorrichtung wird nicht in einen speziellen Lernmodus geschaltet sondern läuft von Anfang im scharf geschalteten Betriebszustand und misst in diesem laufend die Leistungsparameter. Zu Beginn wird der normale Betriebszustand eine relativ grosse Bandbreite aufweisen und die Vorrichtung wird eher unempfindlich sein. Mit der Zeit wird die Bandbreite des normalen Betriebszustands automatisch eingeschränkt.
- Gefahrenstufe 0:
- Keine Abweichung vom normalen Betriebszustand ⇒ kein abnormaler Betriebszustand.
- Gefahrenstufe 1:
- Geringe Abweichung vom normalen Betriebszustand ⇒ eventuell abnormaler Betriebszustand.
- Gefahrenstufe 2:
- Mittlere Abweichung vom normalen Betriebszustand ⇒ wahrscheinlich abnormaler Betriebszustand.
- Gefahrenstufe 3:
- Grössere Abweichung vom normalen Betriebszustand ⇒ abnormaler Betriebszustand.
