    TECHNICAL FIELD The invention relates to a rail vehicle with a
    Rail chassis-supported wagon frames and a wagon body with at least one driver's cabin, wherein a travel drive comprises an electric motor supplied by an electrical energy store. In addition, the invention relates to a method for fire prevention or for extinguishing fire within an electrical energy store of a rail vehicle.
    State of the art [02] It is not only in the automotive industry that innovative drive concepts are increasingly being used due to increasingly stringent environmental requirements. Cordless railcars and diesel hybrid railcars have also been known in rail vehicle construction for several years. Due to increasingly powerful, lighter batteries, which are becoming cheaper to manufacture, they represent an attractive alternative for the future. Especially for sections of the tune where installation of an overhead line proves to be particularly difficult and cost-intensive, and where emissions caused by internal combustion engines are harmful for a worker battery-powered rail vehicles prove to be particularly advantageous.
    [03] DE 10 2012 216 312 A1, for example, discloses a rail vehicle suitable for battery operation.
    [04] Modern batteries only need a sixth the mass of energy-equivalent lead batteries. This increasingly compact design results in an enormous energy density in a small space. This represents an increased risk of fire, which must be counteracted in a safe and reliable manner.

    SUMMARY OF THE INVENTION [05] The object of the invention is to provide an improvement over the prior art for a rail vehicle of the type mentioned in the introduction.
    [06] According to the invention, this object is achieved by a rail vehicle according to claim 1 and a method according to claim 10. Advantageous further developments of the invention result from the dependent claims.
    [07] The invention provides that the energy store has a temperature control by means of a liquid dielectric and that the car body comprises a compartment which is separated from the driver's cabin and in which the electrical energy store is arranged within at least one fire protection cabinet with a dielectric tank located above it. The temperature control by means of the liquid dielectric ensures a constant operating temperature of the energy store located in the fire protection cabinet. In the event of a fault, the dielectric tank is used to maintain cooling of the electrical energy store. In addition, a spatial division of the driver's cabin and the separate compartment guarantees safe partitioning in the event of a fire.
    In an advantageous embodiment of the invention it is provided that the compartment can be walked on and in particular is separated from the driver's cab by means of a fire protection wall and / or a passage. Because the compartment is accessible, maintenance and inspection work is particularly easy. The additional fire protection wall ensures additional time and safety in the event of a fire.
    [09] In addition, it is advantageous if the electrical energy store comprises an accumulator block, which is formed in each case from a master module and at least one slave module, and if each module comprises a plurality of accumulator cells with a dielectric around them. Due to the modular design, the energy storage is specifically adapted to the operational requirements and the respective area of application. In addition, the battery cells

    3/11 evenly flushed with dielectric and effectively dissipates heat generated during operation.
    It makes sense if the electrical energy storage device comprises several battery blocks, which are arranged in the fire protection cabinet separated by fire protection plates. As a result, the battery blocks are placed one above the other in the fire protection cabinet in a space-saving and efficient manner. An additional separation by fire protection panels is another safety device in the event of a fire.
    A further improvement of the device according to the invention provides that the dielectric tank is connected to the fire protection cabinet via an extinguishing line that can be shut off with a controllable valve. In the event of a fire, the fire protection cabinet is flooded with additional dielectric from the dielectric tank via the open controllable valve.
    In a further improvement of the invention, the dielectric tank is connected to a dielectric circuit for temperature control of the electrical energy store via a compensating line. As a result, the dielectric tank is used as an expansion tank for the dielectric circuit. An increase in volume when the dielectric is heated is compensated for via the compensating line and the dielectric tank.
    [13] It makes sense if the dielectric circuit has at least one pump, one heat pump and one temperature sensor. The pump causes a forced circulation of the dielectric in the
    Dielectric circuit and thus an optimized heat dissipation. The heat pump is used to air-condition the driver's cabin. The heat generated in the electrical energy store is absorbed and raised to a higher temperature level by the heat pump. A heat exchanger is used to exchange heat with a secondary medium for heating or cooling the driver's cabin as required. As a result, less heating or cooling power has to be applied, which leads to a significant increase in the range of the vehicle while maintaining the battery capacity. The temperature sensor monitors the temperature of the dielectric and forwards the values to a controller.

    It is also advantageous if the rail vehicle comprises a signaling unit and if the signaling unit is coupled to a smoke sensor and / or a temperature sensor arranged in the fire protection cabinet. A fire is immediately detected via the smoke sensor and / or temperature sensor located in the fire protection cabinet and an emergency message is sent from the reporting unit to an emergency center.
    A further improvement of the invention provides that a converter is arranged in a separate converter cabinet in the compartment and that at least one aerosol cartridge is arranged in the converter cabinet. Due to the spatial separation of the converter cabinet and the fire protection cabinet, they are separated from each other in the event of a fire. However, if there is a fire in the converter cabinet, it is immediately extinguished using an aerosol cartridge.
    The method according to the invention for fire prevention or fire extinguishing within the electrical energy store provides that in an inoperative state in the event of a leak as a result of an accident, the dielectric emerging from the dielectric tank is compensated for by means of a dielectric via an open extinguishing line. In the event of a leak or a blown battery cell, the open, controllable valve allows the dielectric to flow freely through the fire protection cabinet.
    It makes sense if the extinguishing line is opened by means of a solenoid valve that has become de-energized when the rail vehicle is taken out of service. As a result, the solenoid valve remains open when the rail vehicle is parked, even if the power supply fails, so that the dielectric can flow freely into the fire protection cabinet in the event of a fire.
    Furthermore, it is advantageous if, in an operating state with a temperature limit detected within the electrical energy store, a cooling capacity of a dielectric circuit is increased and if a change in volume of the dielectric is compensated for via a compensating line between the dielectric circuit and the dielectric tank.
    The temperature of the dielectric is continuously monitored

    Fire protection cabinet detected. When the temperature limit is reached, the cooling capacity is increased by increasing the dielectric circulation.

    DESCRIPTION OF THE EMBODIMENTS [21] FIG. 1 shows a rail vehicle 1 shown in simplified form with a carriage frame 3 supported on rail running gear 2 and a carriage structure 4 which has a passage 6 in the machine longitudinal direction 5 between an end driver's cab 7 and a compartment 8. In addition to the passage 6, the compartment 8 is separated from the driver's cab 7 by means of a fire protection wall 9. A second driver's cab 10 is located on the opposite end side. A work platform 11 is arranged between the compartment 8 and the second driver's cab 10. A travel drive comprises an electric motor 13 supplied by an electrical energy store 12.
    [22] A top view of the compartment 8 is shown in FIG. Two double fire protection cabinets 14 are arranged next to one another on the side facing away from the driver's cabin 7. A dielectric tank 15 is located above each double cabinet 14. Conversely, converters 16 are positioned in converter cabinets 17. There is an accessible area between the fire protection cabinets 14 and the converter cabinets 17

    6/11 provided. A heat pump 18 is arranged in this area in order to use a heat emitted by the electrical energy store 12.
    3 shows a schematic section through compartment 8 with a front view of the two double fire protection cabinets 14 and the dielectric tanks 15 located above them to clarify the arrangement. The fire protection cabinets 14 are spaced apart from one another by means of a plurality of uprights. In this way, simple installation and removal of the fire protection cabinets 14 is possible using a forklift.
    4 shows the schematic structure of the electrical energy store 12 within a fire protection cabinet 14. In this case, three accumulator blocks 19 are arranged one above the other, each of which is separated from one another by fire protection plates 20. The walls of the fire protection cabinet 14 are also lined with fire protection plates. An accumulator block 19 is composed of a master module 21 and three individual slave modules 22. Each module 21, 22 is composed of a plurality of battery cells 24, which are flushed with a dielectric 23.
    [25] By means of the dielectric 23, the battery cells 24 are tempered and thus operated in an optimal temperature range. If a battery cell 24 overheats or ignites, the dielectric 23 also functions as an extinguishing agent, which prevents the battery cells 24 from reaching over. A dielectric circuit 25 is provided for tempering the dielectric 23.
    5 shows in a schematic block diagram a thermal management of the energy store 12 with the dielectric circuit 25 and a second cooling circuit 26, which is provided for the temperature control of the driver's cab 7 and other units. The second cooling circuit 26 is operated with a glycol mixture and comprises an external cooler 71 and an auxiliary heater 28 if a heat provided in the heat pump 18 is not sufficient.
    Units connected to the second cooling circuit 26 are, for example, the electric motor 13 and a generator 29, which is coupled to an internal combustion engine and for charging the electrical one

    Energy storage 12 is used. A heat exchange takes place between the dielectric circuit 25 and the second cooling circuit 26 via a heat exchanger 30.
    [28] The dielectric circuit 25 comprises a temperature sensor 31, which is connected to the heat pump 18 via a signal line 32. The heat pump 18 is supplied via a converter 33, which is connected to a controller 34 via a further signal line 32.
    [29] From the heat pump 18 via the heat exchanger 30, a feed line 35 leads to pumps 36 which pump into each energy store 12 within a fire protection cabinet 14 with a dielectric 23. Each energy storage device 12 is temperature-controlled separately within a fire protection cabinet 14 by means of a regulated pump output. A return line 37 leads the dielectric 23 back to the heat pump.
    6 shows the dielectric circuit 25 without a second cooling circuit 26. Four energy storage devices 12, each housed in a fire protection cabinet 14, are arranged with a common dielectric tank 15. The dielectric tank 15 is connected to the return line 37 above the fire protection cabinets 14 by means of an extinguishing line 38. In regular operation, the extinguishing line 38 is shut off by means of a solenoid valve 39 which is under current.
    [31] When the rail vehicle 1 is parked or in the event of a power failure, the solenoid valve 39 is open. As soon as a leak occurs in the system as a result of a defective battery cell 24, dielectric 23 automatically flows as a result of gravity via the extinguishing line 38 and the return line 37 into the energy store 12 concerned. The defective battery cell 24 thus remains surrounded by dielectric 23 even when the rail vehicle 1 is without current, so that overheating or a cell fire can be contained before neighboring battery cells suffer 24 damage.
    [32] A volume equalization of the dielectric 23 between the dielectric circuit 25 and the dielectric tank 15 takes place via your equalization line 40. This is equipped with a shut-off valve 41 in order to close the dielectric tank 15 for maintenance purposes. The dielectric tank 15 also includes a lid

    8/11 a vent valve 42. For maintenance purposes, a drain line 43 with a drain valve 44 is also arranged on an underside of each fire protection cabinet 14.
    [33] As an additional safety measure, each accumulator block 19 of the energy store 12 is assigned two temperature sensors 46. A smoke sensor 45 is also arranged in the upper region of the respective energy store 12. These sensors 45, 46 are connected to a signaling unit 45 via a signal line 32. As soon as a predefined temperature limit is exceeded or smoke is detected, a message is sent to an emergency center. The signaling unit 47 advantageously has its own battery so that it can also be used when the vehicle 1 is parked.
    [34] In addition, each temperature sensor 46 is connected to the controller 34 via a signal line 32. If an increased heating of an energy store 12 is detected, the pump output of the corresponding pump 36 is increased by means of the controller 34, which is achieved thereby
    Increased cooling capacity for the additional heat and prevents a critical operating temperature from being exceeded.
    7 shows a schematically illustrated converter cabinet 48 with a converter 33 located therein, in which two aerosol cartridges 49 are arranged for extinguishing in the event of a fire.
