Definitions

  • the influence of the device on the supply circuit varies according to the operating conditions of the device itself.
  • the inductance is high only when the lamp is on. Consequently, as long as the lamp is not lit, the reactive power due to the capacitor is not compensated and this results in disturbances on the network as long as the discharge lamp is connected to the network without being switched on.
  • a discharge lamp can only light up when the gases it contains have cooled down.
  • the lamps go out and can only re-light after a certain time during which the capacitors create a disturbance on the network.
  • a short cut leading to the extinction of the lamps subsequently causes a very significant disturbance which must be compensated by a increase in the power supplied to the network, failing which the reactive power of the capacitors is not compensated and the discharge lamps cannot be re-ignited.
  • a device for controlling an electrical circuit characterized in that it comprises a first controlled switch open at rest, mounted on the electrical circuit, a second controlled switch, closed at rest, mounted in parallel with the first controlled switch, supply means of the control device connected to the electrical circuit upstream of the first and second controlled switches, first time-delay control means connected to the first controlled switch, second means of timing control connected to the second controlled switch and memory means connected to the second controlled switch, the timing of the first control means being at most equal to the timing of the second control means.
  • the timing means comprise a resistor, one terminal of which is connected to the supply means and the other terminal of which is connected on the one hand to the input of the first flip-flop corresponding and on the other hand to a first terminal of a capacitor
  • the holding means comprise a second flip-flop whose input is connected to the output of the first flip-flop and whose output is connected to a second terminal of the capacitor opposite to the first one.
  • the control device of an electrical circuit 1 comprises a first switch 2, open at rest,. controlled by a coil 3 and mounted on the electrical circuit 1, a second switch 4 closed at rest, mounted in parallel with the first switch 2 and controlled by a coil 5.
  • the timing means 23 also include a capacitor 27 one of the terminals of which is also connected to line 26, while the other terminal is connected to ground through the inter medium of means for holding the control means in an activated position.
  • These holding means are formed by a second flip-flop 28, one of the inputs of which is connected directly to ground and the other input of which is connected by a line 29 to the output of the first flip-flop 18, the output of the flip-flop 28 being connected to the terminal of the capacitor 27 which is opposite to the terminal of this same capacitor connected to the input of the rocker 18.
  • Second timing control means comprise, in the same way as the first timing means 17, a flip-flop 31, connected via a resistor 32 to an NPN transistor 33.
  • Timing means 34 comprise a resistor 35, one of which terminals is connected to the supply means 6 by a line 36 and the other terminal of which is connected to the input of the rocker 31.
  • the timing means 34 also comprise a capacitor 37, a first terminal of which is connected to the input of the flip-flop 31 and the opposite terminal of which is connected to the output of a flip-flop 38 forming means for holding the control means 30 in an activated position.
  • the flip-flop 38 has one of its input terminals connected to ground and the other input terminal connected to the output of the first flip-flop 31 by a line 39.
  • the emitter of transistor 33 is connected to ground by a line 40 and the collector is connected to memory means 41, by means of a decoupling diode 42.
  • the memory means 41 include a capacitor 43, one of which terminals is connected to the supply means 6 by a line 44 and is associated with a resistor 46, mounted in parallel with the terminals of the capacitor, by means of a resistor 45.
  • the memory means 41 further comprise a second resistor 47, mounted in parallel with the first resistor 46 and in series with a switch 48, open at rest and controlled by a coil 49, one terminal of which is connected to the supply means 6 by a line 50 and the other bounded of which is grounded.
  • the signal of the memory means is amplified by a PNP transistor 51, the base of which is connected to one of the common terminals of the resistors 46 and 47, the emitter of which is connected to the supply means 6 by a line 52 and of which the collector is connected to the base of an NPN transistor 53, via a resistor 54.
  • the collector of transistor 53 is connected to the terminal of the coil 5 opposite to that which is connected to the supply means 6
  • the emitter of transistor 53 is connected to ground by a line 55 and its base is also connected to ground via a resistor 56.
  • Diodes 57, 58 and 59 are respectively mounted in parallel with the coils 3, 5 and 49 in order to protect the transistors against self-induction of these coils, during the interruption of the current therein.
  • the operation of the device is as follows when establishing the connection with the AC voltage source 60, the switch 4 is closed and the current can flow normally towards the use, for example, a discharge lamp 61 which is cold and then lights up instantly.
  • the flip-flop 18 is at rest and the transistor 20 is therefore blocked.
  • the coil 3 is therefore not energized and the switch 2 is open.
  • the coils 3 and 5 cease to be excited and the switches 2 and 4 return to their rest position.
  • the capacitors 27 and 37 discharge almost instantaneously and the rockers 18 and 31 return to their initial state.
  • the capacitor 43 which has been charged, via the transistor 33, during the preceding supply period, keeps the transistor 51 conductive and gradually discharges through resistors 45, 46.
  • the flip-flop 18 remains in the idle state as long as the capacitor 27 is not charged again and the switch 2 therefore remains open during this time.
  • the transistors 51 and 53 are kept conductive by the discharge of the capacitor 43 and the coil 5 is therefore excited, which opens the switch 4. Consequently, as long as the capacitor 43 is not discharged, the device 61 is disconnected from the network.
  • the capacitor 43 is chosen to have a discharge time equal to the cooling time of the lamp, so that when the switch 4 closes the ignition of the lamp 61 can be instantaneous and not cause disturbances on the network.
