The invention relates to a rail vehicle (SFZ) with fire protection. The rail vehicle has a battery system (BATS) with the aid of which traction energy is stored for the rail vehicle or is made available to said rail vehicle for driving. The battery system is arranged in a box-shaped fire protection arrangement (BSA), the side walls of which and the base of which are water-tight and are connected to one another in a water-tight manner. The fire protection arrangement is dimensioned in such a way that the side walls project vertically beyond the battery system arranged therein. The fire protection arrangement has an inlet with the aid of which the fire protection arrangement can, in the event of a fire in the battery system, be filled with an extinguishing agent from the outside.

Description

Schienenfahrzeug mit Brandschutz Rail vehicle with fire protection
Die Erfindung betrifft ein Schienenfahrzeug mit einem Brand schutz. The invention relates to a rail vehicle with a fire protection.
Eine zunehmende Anzahl an Schienenfahrzeugen werden in Zu kunft Batteriesysteme aufweisen, mit deren Hilfe für das Schienenfahrzeug Traktionsenergie gespeichert bzw. diesem zum Antrieb zur Verfügung gestellt wird. In the future, an increasing number of rail vehicles will have battery systems that can be used to store traction energy for the rail vehicle or make it available for propulsion.
Diese Batteriesysteme werden aufgrund der Kapazität sowie der Lade- und Entlade-Eigenschaften bevorzugt aus Lithium-Ionen- Batteriezellen aufgebaut sein. Due to the capacity and the charging and discharging properties, these battery systems are preferably made up of lithium-ion battery cells.
Bei einem Brand einer Batteriezelle entstehen hohe Temperatu ren, die im ungünstigen Fall den Batteriebrand beschleunigen: durch die hohen Temperaturen werden bislang am Brand unbetei ligte Batteriezellen über eine Kettenreaktion zusätzlich in Brand gesetzt, bis letztlich alle Batteriezellen des Batte riesystems brennen. If a battery cell catches fire, high temperatures occur which, in the worst case, accelerate the battery fire: the high temperatures also set fire to battery cells that were not previously involved in the fire via a chain reaction, until ultimately all battery cells in the battery system burn.
Zusätzlich wird beim Brand einer Lithium-Ionen-Batteriezelle aufgrund der Zellechemie Sauerstoff freigesetzt, der in den Batteriezellen enthalten ist, wobei der Sauerstoff stark brandbeschleunigend wirkt und ein Löschen des Batteriesystems von außen verhindert. In addition, when a lithium-ion battery cell catches fire, the cell chemistry releases oxygen contained in the battery cells, with the oxygen having a strong fire-accelerating effect and preventing the battery system from being extinguished from the outside.
Beim Schienenfahrzeug sind beim Brand eines Batteriesystems weitere schwerwiegende Folgen zu erwarten. Befindet sich das Schienenfahrzeug beispielsweise in einem Tunnel oder in einem Bahnhof, werden Rauchentwicklung bzw. giftige Rauchgase eine Personenrettung sowie eine Brandbekämpfung deutlich erschwe ren bzw. gänzlich verhindern. In the case of rail vehicles, further serious consequences are to be expected if a battery system catches fire. If the rail vehicle is in a tunnel or in a train station, for example, smoke or toxic fumes will become a problem Rescuing people and fighting fires are made significantly more difficult or completely prevented.
Es ist bekannt, ein brennendes, elektrisch angetriebenes Au tomobil, das über ein relativ überschaubares Batteriesystem verfügt, mit Hilfe eines Krans in einen nach oben offenen und mit Löschwasser gefüllten Tank zu verbringen. In diesem Tank wird das Automobil dann für längere Zeit belassen, bis der Batteriebrand zu einem Ende gekommen ist. Durch das Wasser erfolgt im Wesentlichen eine Abkühlung des Brandherds bzw. eine Reduzierung der Zündtemperatur, so dass letztlich ein Löscherfolg erzielt wird. It is known that a burning, electrically driven car, which has a relatively manageable battery system, can be moved into an open-topped tank filled with extinguishing water using a crane. The automobile is then left in this tank for a longer period of time until the battery fire has come to an end. The water essentially cools down the seat of the fire or reduces the ignition temperature, so that the extinguishing process is ultimately successful.
Nachteilig ist an dieser Vorgehensweise, dass sowohl Tank als auch ein geeigneter Kran samt Hebemitteln seitens der Feuer wehr vorgehalten und zum Einsatzort transportiert werden müs sen. Zeitkritisch und lebensgefährlich ist im Einsatz das An bringen der Hebemittel an das brennende Automobil sowie das Verbringen in den Tank, so dass diese Vorgehensweise bei ei nem Vollbrand des Automobils sicher ausscheiden wird. The disadvantage of this approach is that the fire brigade has to keep the tank and a suitable crane and lifting equipment available and transport them to the site. Attaching the lifting gear to the burning automobile and placing it in the tank is time-critical and life-threatening, so that this procedure will certainly be ruled out in the event of a full-blown automobile fire.
Ein derartiges Vorgehen scheidet bei der Brandbekämpfung bei einem Schienenfahrzeug aufgrund des Gewichts des Schienen fahrzeugs sowie der Größe des zum Antrieb benötigten Batte riesystems sicher aus. Such a procedure is ruled out when fighting a fire in a rail vehicle due to the weight of the rail vehicle and the size of the battery system required to drive it.
Es ist daher die Aufgabe der vorliegenden Erfindung, einen Brandschutz für ein Schienenfahrzeug anzugeben, mit dem ein Brand eines im Schienenfahrzeug angeordneten Batteriesystems sicher beherrschbar ist. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen An sprüchen angegeben. It is therefore the object of the present invention to specify fire protection for a rail vehicle with which a fire in a battery system arranged in the rail vehicle can be safely controlled. This object is solved by the features of claim 1. Advantageous developments are specified in the dependent claims.

The fire protection arrangement has an inlet, with the help of which the fire protection arrangement can be filled from the outside with an extinguishing agent, for example with water.
Im Brandfall wird über den Einlauf solange Löschmittel in die Brandschutzeinrichtung geführt, bis das darin angeordnete, brennende Batteriesystem mit dem Löschmittel bedeckt bzw. der Brand erstickt ist. In the event of a fire, the extinguishing agent is fed into the fire protection system via the inlet until the burning battery system inside is covered with the extinguishing agent or the fire has been smothered.
