    Description: The present invention relates to a cabinet with at least one battery arranged therein.
    Such cabinets, which are known, for example, as battery cabinets, in which only batteries and their accessories are stowed, or as combination cabinets, in which, in addition to batteries, other functional parts are stowed, are used, for example, for batteries in systems for uninterruptible power supply, such as emergency lighting systems , Since there is a risk of gaseous hydrogen and gaseous oxygen being generated during charging and / or a defect in a battery and accumulating in the cabinet up to a fire or even explosive detonating gas mixture, the cabinets must be adequately vented. This is particularly necessary if the cabinet is a combination cabinet and switchgear is also provided, which is particularly the case with emergency power lighting systems. In such switchgear, sparks can occur due to switching operations, which could ignite a combustible or explosive mixture. Irrespective of the presence of integrated switchgear, an ignitable mixture could also come into contact with an ignition source when or shortly after the cabinet is opened, for example if a sparking metal door in the battery cabinet creates a spark. However, the provision of ventilation is disadvantageously very complex.
    Ventilation of the cabinet is particularly complex when the cabinet is to meet high fire protection regulations, since a transition between the interior and the exterior is correspondingly complex.
    Cabinets in which ignitable gas mixtures could accumulate are usually vented outdoors. Depending on the weather, the supply air supplied to the cabinet can be very cold or very warm, so that disadvantageous air conditioning for the cabinet must be provided in order to set a temperature range in which the batteries work reliably and safely. This air conditioning must also meet any fire protection regulations.
    The invention has for its object to provide a cabinet in which no ignitable gas mixture can accumulate and which does not have the disadvantages mentioned above.
    The object is achieved in a cabinet with the features of the preamble of claim 1 in that the at least one battery or a single housing with at least one battery arranged therein has a ventilation connection and a hose or pipe is connected to the ventilation connection or which is led out of the cabinet or is connected to a hose or pipe led out of the cabinet.
    From the battery, possibly arising gas can then only escape through the vent connection and / or the hose or pipe led out of the cabinet and thus not get into the cabinet, so that there is no longer any risk of accumulation inside the cabinet. It is therefore not necessary to vent the cabinet. For this purpose, the batteries can be designed in such a way that areas in which gas can be generated are sealed off from the cabinet. If batteries are used that are not designed or cannot be designed in this way, airtight individual housings with a ventilation connection with a battery arranged therein can be arranged in the cabinet.
    An air conditioning system for the cabinet can be designed correspondingly smaller or even completely passive without a ventilation system, since there are no more temperature changes due to supply air and exhaust air flows. The cabinet can thus be manufactured more cost-effectively and requires less energy in operation.
    Of course, it is also within the meaning of the invention if several batteries are arranged in the cabinet. The hoses and / or tubes of each individual battery can then either be led out of the cabinet separately from one another or else brought together within the cabinet and led out of the cabinet via a main line. This means that even larger systems that need the capacity of many batteries can be supplied with a single cabinet. It is also conceivable to provide a connecting hose or a connecting tube for each battery location in the cabinet, which can be connected to a battery and has means for disconnecting the tube or closing the tube when the battery is not connected. In this way, the same cabinet can be equipped and used for systems of different sizes.
    Usually, the cabinet is arranged in a room with a much larger volume of air than is present in the cabinet itself. Insofar as the gas escaping from the battery flows into the space surrounding the cabinet, the absolute amount of detonating gas or hydrogen until a combustible mixture is reached is substantially greater than it would be compared to the air volume inside the cabinet. Depending on the number and operating parameters of the batteries and the dimensions of the surrounding space, ventilation to the outside may not be necessary. A safety device, such as a sensor system that measures the gas content in the room air, can of course be provided for this in the room surrounding the cabinet.
    But it is also conceivable that the or the hose or tube led out of the cabinet or the hoses or tubes led out of the cabinet from the room in which the cabinet is arranged and / or led out of the building is or are in which the cabinet is located or are connected to at least one such hose or tube.
    It is also within the meaning of the invention that at least one switchgear is arranged in the cabinet and it is therefore a combination cabinet. Such switchgear, as already described, are potential sources of ignition
    CH 714 988 A2 len. However, since the invention no longer allows an ignitable gas mixture to accumulate inside the cabinet, the switchgear can be arranged in the cabinet without further extensive safety measures, so that, for example, two functions can be accommodated in a cabinet for emergency power lighting systems - the Storage function as well as the control function.
    [0013] The at least one switchgear can be arranged particularly advantageously in close proximity to at least one battery. In the case of previously known cabinets, an ignitable gas mixture can accumulate, particularly in the immediate vicinity of the battery. For this reason, potential ignition sources in known cabinets are always arranged at a minimum distance from the batteries, even if the battery cabinets are vented. Such a minimum distance need not be taken into account in a cabinet according to the invention, so that the batteries and the switchgear can be arranged in the cabinet in a much more space-saving manner.
    The invention can also be used particularly advantageously in fire-protected cabinets or cabinets which must or should meet a function maintenance criterion. A function maintenance criterion means, for example, that the cabinet must protect the functional parts arranged in it for a certain time (e.g. 30 minutes or 60 minutes) from the effects of flames and flames in the event of a fire so that they remain functional. Advantageously, a cabinet according to the invention does not require a complex transition between the interior and the exterior of the cabinet for ventilation. The necessary implementation for a hose or a pipe can be made fire-protected or fire-proof in a relatively simple and inexpensive manner.
    In the following the invention will be explained in more detail with reference to figures in which previously known battery cabinets and preferred exemplary embodiments of the invention are shown.
    [0016] It shows in top view:
    Figure 1 shows a cabinet in an ambient room with a vent to the outside according to the prior art.
    2 shows a cabinet according to the invention in a first embodiment;
    3 shows a cabinet according to the invention in a second embodiment;
    Fig. 4 shows a cabinet according to the invention in a third embodiment.
    Fig. 1 shows a cabinet 1 according to the prior art in an ambient space 2. In the cabinet several batteries 3 are arranged, any gases escaping from the batteries 3 escape into the free air volume 4 of the cabinet 1. In order to counteract an enrichment towards an ignitable gas mixture within the cabinet 1, a vent 5, 6 is provided with an exhaust air duct 5 and a supply air duct 6, which connect the free air volume 4 of the cabinet 1 to the outside air 8. For this purpose, air compressors 10, 11 can be provided in the exhaust air duct 5 as well as in the supply air duct 6 in order to generate an air flow or an air circulation. It is also conceivable that only one exhaust air duct 5 with a compressor 10 is provided and that the cabinet 1 is not completely airtight with respect to the surrounding space.
    Fig. 2 shows a cabinet 1 according to the invention in an ambient space 2. In the cabinet 1, in turn, a plurality of batteries 3 are arranged. Each of the batteries 3 has a ventilation connection 13, on which a hose 14 is arranged, via which the gases generated on the battery 3 are led to the collecting hose 15. The collecting hose 15 is led out of the cabinet 1 and opens into the surrounding space 2. Furthermore, in the embodiment shown in FIG. 2, a switchgear 7 is arranged in the cabinet 1 in the immediate vicinity of the batteries.
    Fig. 3 shows a cabinet 1 according to the invention according to Fig. 2, wherein in the embodiment shown in Fig. 3, the collecting hose 15 is not led into the surrounding space 2, but outside to the outside air 8. Such an arrangement can preferably be selected if large amounts of gas are expected and / or the surrounding space 2 has such a small air volume that in the embodiment shown in FIG. 2 an ignitable enrichment of the gas in the surrounding area would have to be expected.
    Fig. 4 shows a cabinet 1 according to the invention, in which an individual housing 17 is provided for each battery 3, which in turn has a vent connection 13. The individual housing 17 are made airtight. In turn, hoses 14 for guiding the gas to the collecting hose 15 are arranged on the ventilation connections 13.
