Definitions

  • the invention relates to a method for controlling an AC network operated and switching a load current electromechanical Relay, as well as on a device for performing the method.
  • Relays are often used when a large load current is used by means of a small one Control current is to be switched, e.g. when used as an installation switch.
  • the advantages of mechanical relays are their high robustness and small construction volume at a relatively low price.
  • Electromechanical face high demands Components when large starting currents, e.g. with capacitive or Incandescent lamp loads occur, must be switched. Bulb loads are marked by a factor of about 10 in relation to the starting current to the Current in the stationary final value.
  • Capacitive loads occur when used as installation switches, e.g. when switching electronic transformers, energy saving lamps or electronic ballasts for fluorescent lamps.
  • the invention is therefore based on the object of a method for operating a specify electromechanical relays on an AC network with a particularly low load on the relay contacts due to starting currents Switching on a load is reached.
  • a facility to carry out of the procedure is therefore based on the object of a method for operating a specify electromechanical relays on an AC network with a particularly low load on the relay contacts due to starting currents Switching on a load is reached.
  • the switch-on delay selected in this way is that they close the relay contact along with the relay response time at the time of a zero crossing, or at least in the vicinity of one Zero crossing of the AC voltage causes.
  • Fig. 1 shows a block diagram of a device for performing the method.
  • a load 1 is by means of a relay contact 2 of an electromechanical relay 3 connectable with an alternating voltage via conductor N, L.
  • the one belonging to relay 3 Relay coil 4 is controlled by an electronic control unit 5 which can be realized by means of a microcontroller.
  • the control unit 5 is via a A switching command can be fed to input E.
  • Lead to the AC voltage Conductor N, L is connected to a line voltage zero crossing detector 6, which is a Forms zero crossing signal and feeds the control unit 5.
  • a current pulse detector 7 in conjunction with a measuring device 8 delivers a current pulse measured value after the respective closing of the relay contact 2 to the control unit 5.
  • the estimated value is selected depending on the design of relay 3.
  • control unit 5 A possible operation of the control unit 5 is described below.
  • the control unit 5 If the control unit 5 is supplied with a switching command at the input E, it drives the relay coil 5 after a delay T.
  • the starting current pulse dI occurring in the load circuit after the relay contact 2 has been closed is detected as a measured value by means 7, 8 and supplied to the control unit 5.
  • the delay time T is incremented or decremented by the adaptation value dT for the subsequent switch-on process, which can be specified as a constant K, so that, after at least a few switch-on processes, the contact closing time differs from the time t 0 of the AC zero crossing by ⁇ dT is reached.
  • the amount of the current measurement value can be used and compared with a threshold value C, whereby an adjustment the delay period is omitted when the predetermined threshold C is not reached by the measured current pulse.
  • the magnitude of the measured current pulse can also be used to form a dependent step size of the adaptation value dT.
  • it is not the constant K, but a variable value that is used to form the adaptation value dT.
  • the desired optimum for the activation time can thus be achieved with a smaller number of switching cycles and, moreover, a switch-on time practically corresponding to the zero crossing t 0 can be achieved.
