Definitions

  • the invention relates to a circuit arrangement for actuating excitation coils of electronic tronaanet switching devices using a capacitor lying parallel to the actuation aspect and an on / off switch for the arrangement.
  • the opening delay in contactors that are already in operation cannot be simply increased in alternating current controls by an additional module; because AC systems have a resistance that is too low for DC operation and thus also one for the Ent charge too low time constant.
  • the invention is therefore based on the object of improving a circuit arrangement of the type mentioned above in such a way that in order to achieve an opening delay using a condenser which can be charged with direct current, the use of an alternating magnetic system is possible without having to make a considerable effort. This is achieved in a simple manner in that the capacitor is preceded by a clock generator in parallel and the excitation coil by an electronic switch controlled by the clock generator.
  • the fall times can be set easily if the clock generator is adjustable.
  • the clock generator is preceded by a timing element.
  • the so-called direct current saving circuits with series resistors which are bridged for the switch-on process, or double winding systems with pull-in and holding windings can be dispensed with.
  • setting the timer can be advantageous. If a free-wheeling diode is connected in parallel to the excitation coil, the decelerated degradation of the coil energy is achieved during the pause read by the clock generator via the electronic switch.
  • the circuit arrangement is preceded by a diode in the forward direction of the electronic switch. This Diede is when connected to an AC source to charge the Capacitor with bleaching pin is definitely required.
  • the components of the circuit arrangement are combined to form a structural unit which can be electrically and mechanically connected to the electromagnetic control device.
  • the clock generator 3 and the capacitor 4 are connected in parallel to the series circuit comprising the excitation coil 1 and the transistor 2 forming the electronic switch.
  • the parallel connection is already separated from the mains terminals 5, 6 by the open switch 7.
  • a diode 8 provides the possibility of being able to connect the circuit arrangement to both weekly and direct voltage.
  • the freewheeling diode 9 causes a slow reduction in the coil energy during the pulse-free pause predetermined by the clock generator 3 via the transistor 2, so that the current flow in the coil I s over time results in FIG. 2.
  • I over time represents the current flow in the discharge circuit during clocking.
  • the current flow in the excitation coil is therefore also in clocked operation, as shown in FIG. 2, not completely at zero, so that the electromagnetic switching device as long as the capacitor 4 outputs the necessary voltage , remains switched on.
  • a timer 10 cooperating with the clock generator 3 causes the transistor to first switch on the transistor 2 for a predetermined time corresponding to the timer.
  • the excitation coil receives 1 switch-on command, and the high current which is limited and awakened only by the ohmic coil resistance allows the electromagnetic switching device to be switched on.
  • the clock generator 3 changes to the clock mode.
  • the impula-pause ratio is to be chosen so that the contactor coil is not thermally overloaded, as was ensured in known arrangements by connecting the economy resistor.
  • the arrangement according to the invention thus creates an arrangement which can take on the function of drop-delayed contactors as well as the function of constant-voltage saving circuits without the need for a separate wall.
