  • the invention relates to a device according to the preamble of claim 1.
  • Burn-up indicators for the contact pieces are also known, which are mechanically operated via levers or cables to be controlled; also the recording of the number of operating hours via clock counters.
  • Temperature recorders for the temperature / time behavior as well as safety circuits for fault messages, i. H. Notification of an unwanted switch triggering can be used.
  • a device for checking the operability of electrical switching devices is also known from DE-C2 27 27 378, in which the output current of a current transformer is used as the input variable of a switch-off current and switching piece erosion linking the function converter.
  • the output variable of the converter is given to an accumulator by means of an auxiliary switch, the content of which forms a measure of the erosion of the switch pieces caused in previous operation.
  • An electronic function memory (for example a ROM) is provided as the function converter, in which the burn-up is stored as a numerical value depending on the level of the current to be switched off. With each switch-off, the burn-up value corresponding to the instantaneous value of the current is taken for input into the summing memory.
  • a comparison stage which emits a signal when the sum of the burn-up values exceeds the predetermined target value. or inspections If maintenance work or repairs / are carried out according to a rigid scheme corresponding to the number of mechanical switching cycles or the number of operating hours, many other influencing variables inevitably remain unconsidered. When making recommendations for these maintenance intervals, switchgear manufacturers must therefore assume standardized operating conditions.
  • maintenance intervals are selected to be very small to achieve a high level of operational reliability, there may be an uneconomical use of materials and equipment with high maintenance costs.
  • the invention has for its object to develop a monitoring and control device with which it is possible or Inspection of the maintenance / flexible, to be carried out according to the actual requirements of the respective application, the current state of the switchgear or degree of wear and tear being recognizable during operation.
  • Fig. 1 the principle is assumed to measure critical sizes in the new state of various wear parts, i.e. 0% wear corresponds to 100% expected service life (here switching cycles).
  • the respective wear is determined by numerous measurements over the number of operations. Characteristic curves (linear, degressive or progressive) are obtained as a function of the degree of wear depending on the number of switching operations. By extrapolation up to the wear limit (corresponding to the end of the service life) taking into account the scatter band, the remaining switching number to be expected is concluded. A reversal of meaning is also possible.
  • the empirically determined characteristics of the wear behavior of the different wear parts are fixed memory as a function, digitized with scatter band, as a family of curves with various parameters or multidimensionally as a reference map, possibly with its own computer program.
  • FIG. 2 shows a schematic representation of the measured variables detected by sensors, the changes of which are monitored, evaluated directly or determined indirectly by linking dependent data.
  • sensors 1 to 13 are used to record the following circuit or wear conditions: sensor 1 for the switching cycles N (number), sensor 2 the operating time t / a (long-term / date), sensor 3 temperature 1 of the current path, sensor 4 Temperature A 2 of the environment, sensors 5 to 7 for overcurrents Z1 to Z3, sensor 8 for switching / operating voltage U, sensor 9 for voltage drop ⁇ U or earth fault R EI sensor 10 for current steepness di / dt, sensor 11 for contact erosion S ( indirect), sensor 12 for the contact erosion ⁇ S (direct) and sensor 13 for the time constant T.

  • Suitable signal lines 18 are provided, e.g. B. data bus, fiber optic link, this information can also be given to higher-level monitoring service or alarm systems.
  • this status information can be used to immediately identify whether the switchgear / combination needs to be serviced at this or only at the next revision.
  • the query of the current state is even more meaningful with a test case 19 or a computer which communicates with the microprocessor 14 via a bus connection 20 or via the telephone network by means of an acoustic coupler. Leave with it interrogate the "wear switching numbers" entered in the status memories 15 so that it can be seen, if necessary, which wear event led to the acute maintenance indication; whether z. B. increased contact erosion or the high number of mechanical switching operations are the cause (a kind of self-diagnosis). If the sensors for short-circuit and overload detection are switched, z. B. determine whether the contact erosion was caused by a few short-circuit shutdowns or by frequent overload circuits.
  • a significant advantage results from maintenance without a test case if the display field (e.g. 8th segment display) on the switching device as the query menu field 21, i. H. Selection of the various status memories 15 by pressing a key and displaying the content on this display field, is formed (dialog traffic).
  • the display field e.g. 8th segment display

  • the corresponding status memory 15 is then reset, depending on the expansion stage, either on the device itself by means of a button or when using the test case 19 via the data bus 20. It is also possible to permanently enter the number and extent of the maintenance that has been carried out in the status memory 15, and thus to query the history of this switching device during each maintenance.
  • the status memories 15 can also be reset step by step to the required level.
  • the monitoring device can preferably be implemented in various configuration levels and comfort classes, which are characterized by the number of input channels (sensor inputs), type of measurement value linkage (direct or indirect determination), and ease of use (LED line, menu field, test case or acoustic coupler connection and dialage techniques such as touch screen, light pen, measurement or window technology).
  • interfaces are provided which enable interaction with other external protection systems, such as fire and smoke detectors, arcing fault monitors, current rise detection systems, object protection fault alarm systems, etc.
  • this module can also be integrated as a functional unit in other devices or monitoring and protection systems. This is especially true when not only individual switchgear, but entire switchgear combinations (definition according to VDE and IEC) must be monitored.
  • a power supply unit 26 is used for infeed from the voltage network L1, L2, L3 or via current transformers or with both infeeds, which can be selected via bridges 27.
  • An accumulator 28 is provided for the buffered operation of a clock with a date or the core element 14 (microprocessor), in which all information converges and is processed.
  • the program for the microprocessor 14 and a reference map are permanently stored in a read-only memory 29 and the current state of the switching device is stored in a state memory 15.
  • the data content of the memory 15 can be changed, but cannot be lost in the event of a power failure. It is also possible to combine the two read-only memories in a common component 30, since the content of the memory 29 can also be stored in a changeable read-only memory.
  • a clock is labeled with the date.
  • This function can also be implemented by the microprocessor 14. However, continuous operation must be ensured, for example by buffering the supply voltage.
