Definitions

  • the invention is directed to an arrangement, in particular a device or a system, for detecting and possibly reporting smoke and / or a fire in a switchgear cabinet for switchgear or in another, enclosed housing used for the installation of technical systems, and on a method for operating such an arrangement.
  • Control cabinets but also other largely or completely closed rooms with technical installations of a building or a mobile device such as ship, train, plane, etc., are subject to an increased risk of fire.
  • the contact resistance at contact points can increase over time; This increases the power dissipation there, heat is generated which can gradually cause the insulation or other plastic parts to scorch and eventually lead to fire.
  • smoke or fire development is usually only noticed at a very late stage, since the smoke that initially arises does not leave the relevant control cabinet / room and therefore does not reach a building smoke detector or the like. There is therefore a need for early detection of a fire in a control cabinet or other closed room in a technical system.
  • a sensor for a generally relatively slowly changing state variable in particular a sensor for smoke and / or an elevated temperature
  • the sensor or a housing accommodating the sensor having at least one device for positive locking Fixing on a support or mounting element for low-voltage switching devices, preferably a mounting rail, in particular a top-hat rail, is provided.
  • the type of assembly brings a great economic advantage by minimizing the assembly time.
  • the device for fixing the sensor housing to a support or mounting element facilitates the installation of the same in a control cabinet, where the entire rear wall is often covered with such mounting elements, by the most varied of low-voltage switching devices to anchor there. Cable ducts are also usually installed at this location to facilitate wiring. It is precisely in this area that there is an increased risk of a fire being started by improperly laid cables or defective devices.
  • the fact that the sensor according to the invention can be installed here results in a very short distance from the potential sources of fire and thus particularly rapid fire detection.
  • the senor can be mounted in the upper area of the relevant control cabinet. Since smoke development is often accompanied by local heating, air circulation occurs at the point in question, which carries the smoke up into the area of the sensor.
  • the arrangement according to the invention can be of modular construction, for example with at least one sensor module, with an evaluation module, possibly an interface module, a power supply module, etc.
  • This structure allows the operation of several sensors on a common evaluation module, which then - for example for the purpose of common forwarding - summarizes the messages of all sensors.
  • the fastening device can be designed for quick assembly, in particular for snapping onto a mounting rail. This technology makes assembly easier, especially in tight spaces.
  • the fastening device has an element (partially) engaging behind the mounting rail, which is movable approximately perpendicularly or radially with respect to the mounting rail and is pressed behind the mounting rail by a spring element.
  • a top-hat rail for example, the edges of the long sides can be gripped.
  • the mobility of the form-fitting element can be achieved, for example, by using a (limited) elastic material, for example plastic, so that the element engaging behind the mounting rail initially snaps outwards - for example, by means of a ramp-shaped attachment facing the mounting rail is pressed and then springs inwards.
  • a hook-shaped or pocket-shaped attachment on the outside of this element allows a screwdriver or the like to be inserted in order to cancel the positive connection and to detach the (sensor) assembly in question from the mounting rail.
  • the invention further provides that the device or its modules can be plugged onto bases which are fastened or can be fixed in a control cabinet, in particular on a top-hat rail. In this case, a defective module can be replaced in a few simple steps.
  • the housing of the device or the sensor module should have flow openings on at least one side, preferably on two sides, so that the smoke can penetrate into the sensor housing and can reach the sensor.
  • the invention is characterized by at least two through-flow openings which are located on regions of the housing which accommodate or surround the sensor which are approximately opposite one another. This results in an approximately straight flow path through the housing, and approximately vertical by aligning the same, natural convection within the relevant control cabinet can be conducted through the sensor housing with a low flow resistance in order to lead any smoke particles contained directly past the sensor.
  • throughflow openings can be located on two side walls of the housing receiving or surrounding the sensor, which pass approximately perpendicularly through the base plane of a mounting surface supporting the mounting element, so that the direction of flow within the sensor runs approximately parallel to the mounting surface. Since the vertical walls of a control cabinet are mostly used as mounting surfaces, a sensor housing designed in this way can always be aligned on a corresponding mounting surface in such a way that the internal flow direction between the throughflow openings is oriented approximately vertically.
  • the invention can be further developed in such a way that throughflow openings are located on two side walls of the housing receiving or surrounding the sensor, which run parallel to a mounting rail supporting the housing and penetrate the mounting surface carrying it approximately perpendicularly.
  • throughflow openings are located on two side walls of the housing receiving or surrounding the sensor, which run parallel to a mounting rail supporting the housing and penetrate the mounting surface carrying it approximately perpendicularly.
  • the direction of flow within the sensor is oriented approximately transversely to the — usually horizontal — mounting rail. The desired vertical flow is obtained.
  • a cross section parallel to the front of the sensor housing has a rectangular shape, which preferably corresponds in terms of at least one of its dimensions (length and / or width) to a (standardized) cutout in a cover, which surrounds the low-voltage devices fixed on the relevant mounting element , This simplifies the integration of the sensor housing into a recess in a cover.
  • the invention is further optimized by providing a collar or bead on at least one side of the sensor housing.
  • This supports a cover, which surrounds the low-voltage devices fixed on the relevant mounting element, and thus secures the position of the throughflow openings on the desired side of the cover in question, preferably behind it, in order to direct the smoke monitoring specifically to a specific area of the control cabinet.
  • a further development of the invention provides that the operating and / or display elements are arranged on a part of the front that projects over the area having the input and / or output connections and that preferably protrudes over a flat covering of the connections. Such exposed controls and / or display elements are easily accessible or visible.
  • the device or the evaluation module can have at least one display, for example in the form of a lamp such as a lamp or Light emitting diode.
  • a lamp such as a lamp or Light emitting diode.
  • Electrical input and / or output connections or feedthroughs for lines to input and / or output connections arranged within the housing can be arranged on the housing receiving or surrounding the sensor.
  • Such connections and / or bushings are preferably located laterally on the housing or on its upper or lower side, so that the lines in question can be led as straight as possible outwards from the sensor in question and, for example, to a cable duct laid nearby.
  • Electrical input and / or output connections can be arranged in the region of a side of the sensor housing that has no throughflow openings, either directly in such a side or in the vicinity thereof. There, an air flow passing through the housing openings is least disturbed.
  • At least one electrical output of the device or of the evaluation module is designed as a potential-free contact (for fire alarm; remote alarm triggering; indicator light; horn; etc.).
  • signal forwarding can thus be accomplished without an additional module.
  • Equipping the sensor with an interface module enables connection to a preferably digital bus.
  • a bus facilitates the connection of a larger number of sensors according to the invention to a common evaluation unit.
  • a number of adjacent control cabinets can be monitored with their own sensors, for which only a single evaluation unit is required.
  • the interface module should be designed in such a way that the relevant sensor can be addressed. As a result, the status of a specific sensor can be specifically queried by an evaluation unit.
  • the invention allows a further development in that the bus is designed for serial data transmission, for example in the form of a single line. In this case, the wiring becomes much clearer.
  • At least one signal input for the signal of a temperature sensor arranged outside the relevant control cabinet / closed room is provided on the device or the evaluation module.
  • the sensor can possibly obtain further information about the location of the source of the fire, in particular whether it is located inside or outside the relevant control cabinet / closed room.
  • This signal can either be linked directly by the sensor module with the sensor signal, for example to trigger an alarm only in the event of a fire within the relevant control cabinet / room, or the signal is transmitted as information to a higher-level evaluation unit.
  • the device or the evaluation module may have at least one signal output for controlling a device for closing ventilation openings in the control cabinet / closed room, for example by means of a slide valve that falls in a de-energized state in front of the ventilation opening in question. Depending on the location of the source of the fire, this can prevent the spread of fire into / from the relevant control cabinet / room.
  • the device according to the invention or the evaluation module according to the invention preferably has one or more signal inputs for decentrally arranged sensor modules, for example in adjacent switch cabinets or rooms, so that their output signals can also be processed.
  • a parallel connection of several sensors is also possible. This structure is practical when a small number of sensor modules are coupled together, since in such a case the cabling effort is limited on the one hand and the hardware effort is reduced on the other hand.
  • a device in or on the device or the evaluation module is used for the OR combination of the sensor signals connected to a smoke signal or a fire that positively signals sensor modules. This enables a collective signal to be generated for sensor modules connected in parallel, with each smoke alarm triggering an alarm.
  • the device or a power supply module has an uninterruptible power supply, in particular in the form of a battery or an accumulator, which guarantees (emergency) operation over a limited period of time in the event of a power failure.
  • This is particularly important because in the event of a power failure, the risk of fire in a system is by no means eliminated, but may still be increased because, for example, fans or other cooling units are at a standstill.
  • the operating method according to the invention is characterized in that digital information is preferably transmitted between one or more sensors and an evaluation unit. It is also possible to connect analog signals; in such a case, however, a separate line is required for each signal, so that the wiring effort increases considerably; in addition, the risk of transmission errors increases, for example as a result of terminal resistance, line interruptions, temperature effects, etc.
  • the transmitted information is provided with an address identifier, so that several sensors and / or evaluation units can communicate with one another via one and the same bus. This enables a specific query of the information from individual sensor modules. Based on the targeted information obtained in this way, errors or malfunction reports can be assigned to individual sensor modules, and in the event of a fire the source of the fire can be pinpointed fairly precisely.
  • status information of the various sensors is transmitted to an evaluation unit at approximately regular time intervals and evaluated there. This can either be from the Sensors themselves are triggered, however, is preferably carried out by querying the central evaluation unit, for example in a recurring sequence of the connected sensors (in turn, so-called "polling"). As a result, the information about the status of the sensors and their measurement results is updated at short intervals within the evaluation unit, and a fire is therefore detected and reported as soon as possible.

  • the power supply / power supply module 2 is supplied via the input terminals 6 from an external separate circuit fuse with mains voltage 230 V AC.
  • the voltage 24 V DC is made available on the output side 7 of the power supply module 2 via a transformer and the rectifier unit and is transmitted to the input terminals 8 of the evaluation unit 3.
  • the output terminals 10 are used for the supply voltage for the smoke alarm unit 1, input terminals 4.
  • the terminals 9 on the evaluation unit and 5 on the smoke alarm unit are used for monitoring.
  • a built-in battery 21 serves to maintain smoke detection in the event of a power failure.
  • the message "fault” is output via a potential-free contact 16, and the LED 14 - "mains fault” lights up. Both LEDs 14 - “mains failure” and 13 - “smoke detection active" and the smoke alarm unit are supplied by the built-in battery. If the smoke alarm unit 1 is faulty or has failed, the message "smoke detection faulty" is output via potential-free contact 17. This could also be used if the battery ages.
  • the device according to variant 2 is based on the basic device of variant 1. The details described under variant 1 apply in full.
  • the supply voltage 24 V DC is provided on the evaluation unit 3 at terminals 11 for local alarms with indicator lights and horn.
  • the "local alarm” indicator light is activated via a potential-free contact 19 with flashing light.
  • the horn for the local alarm is controlled via the potential-free contact 20.
  • Indicator lights and horn could be installed in the control cabinet door or in a monitoring panel in building technology.
  • the acknowledgment button 15 is actuated, the horn is switched off and the flashing light changes to steady light. The permanent light goes out after the fault has been rectified.
  • Arrangement 1 - 3 of variant 3 is to be used in fire-retardant / fire-resistant control cabinets and door / partition systems.
  • a basic distinction is made between two applications:
  • the fire load encapsulation if there is a fire inside the control cabinet or the locked room or door / partition system, the fire-retardant / fire-resistant encapsulation should prevent the fire from spreading further into a building.
  • the electrical devices such as protective, switching, measuring, regulating and control devices are installed in the above-described housings and encapsulations.
  • waste heat is generated here due to the electrical power loss of the devices. If this waste heat is too high, the electrical devices can fail during normal operation.
