Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Brandschutz hochempfindlicher, insbesondere elektrischer und/oder elektronischer Einrichtungen mittels eines gasförmigen Löschmittels, das hochkomprimiert bevorratet wird und im Brandfall in die zu schützende Einrichtung eingebracht wird.The invention relates to a method and a device for fire protection of highly sensitive, in particular electrical and / or electronic devices by means of a gaseous extinguishing agent which is stored in a highly compressed manner and is introduced into the device to be protected in the event of a fire.
Derartige Vorrichtungen werden üblicherweise zum Schutz von EDV eingesetzt. Die EDV-Geräte werden mit automatischen Branderkennungssystemen versehen und im Brandfall soweit mit Löschmittel beaufschlagt, daß die Sauerstoffkonzentration bis auf einen Wert abgesenkt wird, bei dem die Verbrennung unterbunden wird.Such devices are usually used to protect EDP. The EDP devices are equipped with automatic fire detection systems and, in the event of a fire, are acted upon with extinguishing agent to such an extent that the oxygen concentration is reduced to a value at which the combustion is prevented.
Aus DE 41 16 777 A1 ist ein Verfahren bekannt, bei dem als Löschmittel Stickstoff verwendet wird, der direkt in die zu schützenden Einrichtungen gesprüht wird.From DE 41 16 777 A1 a method is known in which nitrogen is used as the extinguishing agent and is sprayed directly into the devices to be protected.
Hierbei erscheint nachteilig, daß für die direkte Einsprühung in die zu schützenden Einrichtungen Einbauten, zum Beispiel Düsen und Rohrleitungen, in diese erforderlich sind. Derartige Einbauten müssen in der Regel nachträglich angebracht werden, wozu Eingriffe in das Geräteinnere notwendig sind. Weiterhin entstehen so starre Verbindungen zu Löschanlagen, die beim Wechsel von EDV-Geräten nicht unerheblichen Anpassungs- und Montageaufwand erforderlich machen.It appears disadvantageous here that internals, for example nozzles and pipes, are required for direct spraying into the devices to be protected. Such installations usually have to be retrofitted, which requires interventions in the interior of the device. In addition, rigid connections to extinguishing systems are created, which require considerable adaptation and assembly work when changing EDP devices.
Aufgabe der Erfindung war es daher, ein Verfahren und eine Vorrichtung anzugeben, bei der im Inneren der hochempfindlichen elektronischen Einrichtungen keine hochempfindlichen elektronischen Einrichtungen keine Einbauten für die Löschmittelzufuhr erforderlich sind und die Vorrichtung bei Gerätewechsel einfach umsetzbar ist.The object of the invention was therefore to provide a method and an apparatus in which none of the highly sensitive electronic devices highly sensitive electronic devices, no internals are required for the supply of extinguishing agent and the device can be easily implemented when the device is changed.
Diese Aufgabe wird für das erfindungsgemäße Verfahren durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Für die Vorrichtung wird die Aufgabe durch das kennzeichnende Merkmal des Anspruches 6 gelöst.This object is achieved for the method according to the invention by the characterizing features of
Die Unteransprüche 2 bis 5 geben bevorzugte Ausführungsformen des Verfahrens wieder.
Die Unteransprüche 7 bis 9 geben bevorzugte Ausführungen der Vorrichtung an.The
Nach dem erfindungsgemäßen Verfahren wird das gasförmige Löschmittel von außen durch vorhandene Öffnungen im Gehäuse der geschützten Einrichtung zugeführt. Hierbei kann vorteilhaft als Öffnung im Gehäuse der elektrischen Einrichtung die Zuluftöffnung oder die Abluftöffnung für die in der elektrischen Einrichtung erfolgende Luftkühlung genutzt werden. Dieses Verfahren hat den Vorteil, daß Anbauten für die Zufuhr von Löschmittel nur außerhalb des Gehäuses erfolgen müssen. Die Anbauten für die Zufuhr von Löschmittel können darüber hinaus weitgehend standardisiert werden, da Zuluft- und Abluftöffnungen für die Luftkühlung selbst bei unterschiedlichen Gerätetypen im wesentlichen ähnliche geometrische Formen aufweisen. Meistens handelt es sich um in einer Richtung nebeneinander angeordnete Ausnehmeungen im Gehäuse der elektronischen Einrichtung. Damit ist eine Anpassung an die im Gehäuseinneren sehr unterschiedlichen Geometrien, wie sie bei der direkten Einführung von Löschmittel in das Gehäuseinnere erforderlich sind, entbehrlich.According to the method according to the invention, the gaseous extinguishing agent is supplied to the protected device from the outside through existing openings in the housing. In this case, the supply air opening or the exhaust air opening can advantageously be used as an opening in the housing of the electrical device for the air cooling taking place in the electrical device. This method has the advantage that attachments for the supply of extinguishing agent only have to take place outside the housing. The attachments for the supply of extinguishing agent can also be largely standardized, since supply air and exhaust air openings for air cooling have essentially similar geometric shapes, even with different types of devices. Mostly they are recesses arranged side by side in the housing of the electronic device. This means that it is not necessary to adapt to the very different geometries inside the housing, as are required for the direct introduction of extinguishing agents into the interior of the housing.
Bevorzugt kann die Zuführung von Löschmittel über die Abluftöffnung der elektrischen Einrichtung, insbesondere bei abgeschalteter Belüftungseinrichtung erfolgen. Diese spezielle Verfahrensvariante hat den Vorteil, daß Einbauten nur an der Abluftöffnung erforderlich sind, an der ohnehin die automatische Branderkennungseinrichtung anzuordnen sind. Die notwendigen Umbauarbeiten beschränken sich damit auf einen relativ kleinen Teil der elektronischen Einrichtung.Extinguishing agent can preferably be supplied via the exhaust air opening of the electrical device, in particular with the ventilation device switched off. This special process variant has the advantage that installations are only required at the exhaust air opening, where the automatic fire detection device is to be arranged anyway. The necessary renovation work is therefore limited to a relatively small part of the electronic equipment.
Nach einem bevorzugten Verfahren wird die Löschmittelzugabe von einer an der Abluftöffnung angeordneten automatischen Branderkennungseinrichtung gesteuert, welche den Brandfall detektiert und mittels einer Steuereinrichtung die Zufuhr von Löschmittel auslöst.According to a preferred method, the addition of extinguishing agent is controlled by an automatic fire detection device arranged at the exhaust air opening, which detects the fire and triggers the supply of extinguishing agent by means of a control device.
Die automatische Branderkennungseinrichtung besteht üblicherweise aus einem im Bereich der Abluftöffnung des elektronischen Gerätes angeordneten, zum Beispiel rohrförmigen Teil, das Ansaugöffnungen aufweist und mit einem, insbesondere selbstansaugenen Brandmelder, einem sogenannten Aktivmelder verbunden ist. In dem Aktivmelder wird das Auftreten von Rauchgas in der automatische Branderkennungseinrichtung detektiert, und im Brandfall wird ein Signal zur Freigabe eines Löschmittelventils abgegeben. Im Aktivmelder befindet sich üblicherweise ein Gebläse, mit dem Luft durch die Ansaugöffnungen der automatische Branderkennungseinrichtung angesaugt wird. Besonders vorteilhaft wird mit der Öffnung des Löschmittelventils ein zweites Ventil geschlossen, welches die Luftzufuhr zur Meßkammer des Aktivmelders unterbricht, so daß Löschmittel nunmehr durch den rohrförmigen Teil des Branderkennungssystems und die Ansaugöffnungen der automatischen Branderkennungseinrichtung strömt. Da diese Ansaugöffnungen sich unmittelbar im Bereich der Abluftöffnungen der elektronischen Einrichtung befindet, wird das gasförmige Löschmittel in das Innere der elektronischen Einrichtung eingebracht.The automatic fire detection device usually consists of a tubular part, for example a tubular part, which is arranged in the area of the exhaust air opening of the electronic device and has a so-called active detector, in particular a self-priming fire detector. In the active detector, the occurrence of flue gas is detected in the automatic fire detection device, and in the event of a fire, a signal is issued to release an extinguishing agent valve. There is usually a blower in the active detector, with which air is drawn in through the suction openings of the automatic fire detection device. Particularly advantageously, a second valve is closed with the opening of the extinguishing agent valve, which interrupts the air supply to the measuring chamber of the active detector, so that extinguishing agent now flows through the tubular part of the fire detection system and the suction openings of the automatic fire detection device. Since these suction openings are directly in the area of Exhaust air openings of the electronic device is located, the gaseous extinguishing agent is introduced into the interior of the electronic device.
Nach einer weiteren bevorzugten Ausführung des erfindungsgemäßen Verfahrens ist eine gesonderte Einrichtung für die Zuführung von Löschmittel vorgesehen, wobei diese Einrichtung an dem Gehäuse der elektrischen Geräte beweglich angeordnet ist und erst bei Detektion eines Brandfalles fluchtend über die Gehäuseöffnung bewegt wird, so daß an der Zufuhreinrichtung für Löschmittel angebrachte Ausströmöffnungen an der Gehäuseöffnung fluchtend anliegen.According to a further preferred embodiment of the method according to the invention, a separate device for supplying extinguishing agent is provided, this device being movably arranged on the housing of the electrical devices and being moved in alignment over the housing opening only when a fire is detected, so that the supply device for Extinguishing agent openings are flush with the housing opening.
Die erfindungsgemäße Vorrichtung weist Ausströmöffnungen auf, die in einer Zuführeinrichtung angeordnet sind, welche über Zuleitungen mit einem Vorratsbehälter für gasförmiges Löschmittel verbunden sind, wobei die Ausströmöffnungen wenigstens im Brandfall fluchtend zu einer Öffnung im Gehäuse der elektrischen Einrichtung angeordnet sind. Dies hat den Vorteil, daß im Inneren der elektrischen Einrichtung keine Einbauten erforderlich sind.The device according to the invention has outflow openings which are arranged in a feed device and which are connected via feed lines to a storage container for gaseous extinguishing agent, the outflow openings being arranged at least in the event of fire in alignment with an opening in the housing of the electrical device. This has the advantage that no internals are required inside the electrical device.
Nach einer besonderen Ausführungsform der Vorrichtung sind die Ausströmöffnungen für gasförmiges Löschmittel fluchtend mit den Abluftöffnungen der elektrischen Einrichtung angeordnet. Dies hat den Vorteil, daß keine zusätzliche Öffnung im Gehäuse angebracht werden muß und Einbauten nur im Bereich der Abluftöffnung erforderlich sind.According to a special embodiment of the device, the outflow openings for gaseous extinguishing agent are aligned with the exhaust air openings of the electrical device. This has the advantage that no additional opening has to be made in the housing and internals are only required in the area of the exhaust air opening.
Nach einer besonderen Ausführung ist die Zuführeinrichtung am Gehäuse der elektronischen Einrichtung bewegbar angeordnet. Vorteilhaft hierbei ist, daß der normale Abluftstrom an der Gehäuseaußenseite nicht behindert wird. Erst im Brandfall wird die Zuführeinrichtung über die Abluftöffnung bewegt, so daß die Ausströmöffnungen für gasförmiges Löschmittel fluchtend mit den Abluftöffnungen angeordnet sind.According to a special embodiment, the feed device is movably arranged on the housing of the electronic device. The advantage here is that the normal exhaust air flow is not hindered on the outside of the housing. It is only in the event of a fire Feeder moves over the exhaust air opening so that the outflow openings for gaseous extinguishing agent are aligned with the exhaust air openings.
In einer weiteren bevorzugten Ausführung ist die Zuführeinrichtung am Gehäuse der elektronischen Einrichtung klappbar angeordnet. Dies hat den Vorteil, daß lediglich einfache Verriegelungsmechanismen gelöst werden müssen, um die Zuführeinrichtung für gasförmiges Löschmittel in die gewünschte Postition fallen zu lassen.In a further preferred embodiment, the feed device is arranged on the housing of the electronic device in a foldable manner. This has the advantage that only simple locking mechanisms have to be released in order to drop the feed device for gaseous extinguishing agent into the desired position.
Besonders vorteilhaft kann als Zuführeinrichtung die im Bereich der Abluftöffnung vorhandene automatische Branderkennungseinrichtung verwendet werden. Bei dieser Ausführung werden die Ansaugöffnungen des rohrförmigen Teils des Branderkennungssystems als Ausströmöffnungen für das gasförmige Löschmittel verwendet. Anhand von schematisch dargestellten Ausführungsbeispielen werden erfindungsgemäße Vorrichtungen beschrieben.The automatic fire detection device present in the area of the exhaust air opening can be used particularly advantageously as the feed device. In this embodiment, the suction openings of the tubular part of the fire detection system are used as outflow openings for the gaseous extinguishing agent.

Die Löschvorrichtung 6 besteht aus einem Träger 7, an dem eine, zum Beispiel rohrförmige Zuführungseinrichtung 8 angebracht ist. In der Zuführungseinrichtung 8 sind Ausströmöffnungen 9 für gasförmiges Löschmittel vorgesehen. Der Träger 7 weist einen Vorsprung 10 auf, der mit einer drehbar gelagerten Arretiervorrichtung im Eingriff steht. Im Brandfall wird die Arretiereinrichtung 11 zum Beispiel mit einem Elektromagneten aus der Ruhestellung entgegen dem Uhrzeigersinn gedreht. Sobald die Haltevorrichtung 10 freigegeben wird, klappt die Löscheinrichtung um die Drahtkette und liegt dann gegen eine Dichtlippe 12 an dem Gehäuse 1 an. Gleichzeitig wird die Zufuhr von gasförmigem Löschmittel zu der Zuführungseinrichtung 8 freigegeben. Das gasförmige Löschmittel strömt dann in die Abluftöffnung 2 ein. Die erfindungsgemäße Löschvorrichtung 6 ist bevorzugt mit Halteeinrichtungen versehen, die ohne Anwendung von Spezialwerkzeug leicht anbringbar bzw. lösbar am geschützten Gerät sind. Damit ist die Löschvorrichtung bei Gerätewechsel einfach umsetzbar. Entsprechendes gilt für die automtische Branderkennungseinrichtung.In Fig. 1, an
