Definitions

  • the invention relates to a circuit arrangement for supplying energy to electronic tripping devices with a current converter device, the output voltage of which is rectified and can be fed to a charging capacitor which provides the power supply for the electronic tripping device.
  • a circuit arrangement for example from DE-A-32 46 329. If an upper voltage limit is reached, the voltage is short-circuited such that the current of the current converter device no longer flows into the charging capacitor. During this switching process, electromagnetic interference fields occur, which falsify the measuring current and thus lead to faulty tripping.
  • the object on which the invention is based is to define a circuit arrangement for supplying energy to electronic tripping devices which ensures that the current of the current transformer device is influenced as little as possible and furthermore limits the radiation of electromagnetic interference fields to a minimum.
  • the charging capacitor CL is followed by a switched-mode power supply SNT in the manner of a choke-up converter device DR or also a flyback converter (with transformer principle) SW,
  • the switched-mode power supply SNT contains a diode DI for charging an output capacitor CA, which is connected in parallel with the electronic release device AE and serves for its power supply,
  • the switching power supply contains a switching transistor TR for controlling the charging of the output capacitor CA and the switching transistor TR is under the control of a pulse width modulator circuit PW, 1.4 the pulse width modulator circuit PW st so effective that when the target value of an output voltage UA at the output capacitor CA is reached the switching transistor TR can be controlled with a very large duty cycle, ie is only briefly blocking and as a further development of the invention 1.5, a maximum power point controller MPP is provided, which is connected to the pulse width modulator circuit PW in terms of control and controls it with the start of charging the output capacitance CA in such a way that optimum
  • Power adjustment (11,111, 7) is set.
  • a constant current is impressed in relation to the otherwise usual constant voltage supply.
  • the switching transistor is no longer controlled with a small duty cycle, but with a very large one. Accordingly, in the case of very large currents of the current converter device, these are conducted (via the choke step-up converter device) in the switched-mode power supply through the switched switching transistor TR and are only connected through the diode to the output capacitor CA during the very short opening times of the switching transistor.
  • the voltage at the charging capacitor can thus be kept low by this operating mode, so that there is approximately a constant power consumption at a low voltage level.
  • the control electronics of the switched-mode power supply are supplied by the output voltage of the capacitor CA, since the input voltage at the switched-mode power supply is too low, in particular when the current converter device has high currents.
  • the measurement of the current is carried out by a / at a shunt resistor, which can also be arranged in front of the rectifier device if required.
  • Figure 1 shows a first embodiment.

  • Figure 3 shows an embodiment of this training.
  • FIG. 1 The invention is explained in more detail by a first exemplary embodiment according to FIG. 1, in which only the switching elements essential for understanding the invention are shown.
  • the current generated by the current converter device SW is rectified in a known manner by the rectifier device GE and is fed via the choke-up converter converter DR depending on the switching position of the switching transistor TR either to the charging capacitor CL or via the diode DI to the output capacitor CA. .
  • the switching transistor TR is controlled by the pulse width modulator circuit in such a way that when the target value of the output voltage UA at the output capacitor CA is reached, the current of the current converter device SW is conducted to the charging capacitor CL via the switching transistor TR and only during the short opening times of the switching transistor TR the diode DI arrives at the output capacitor CA.
  • the voltage at the charging capacitor CL is thus kept at a low value, so that virtually constant power consumption at a low voltage level is achieved
  • the measurement takes place at the shunt resistor, the so-called shunt, which, if necessary, can also be arranged upstream of the rectifier device GE.
  • this is suitable for high measurement accuracy low resistance, so that the current transformer is almost short-circuit loaded.
  • a second, further developed embodiment for particularly rapid charging of the output capacitor CA shows, explained with reference to FIG. 2, FIG. 3.
  • measures 1 to 1.4 are also provided and measure 1.5 is also added. The latter serves the rapid
  • FIG. 2 shows the characteristic of a current transformer with regard to the course of voltage and current between open circuit and short circuit, with the curves a, b, c and d for different sized current (as a parameter) that flows through the power line S, to which the current transformer relevant here is coupled as a source.
  • the area on the right and above the hyperbola H is the working area available for a circuit according to FIG.

  • the working point of your choice can then be in this area.
  • a switching power supply is provided in the invention is of particular advantage here, because according to one aspect of the invention, depending on the design of the switching power supply with regard to its voltage translation, the output voltage UA at the output of the switching power supply and input of the trigger can optionally be made independent from the input voltage UE at the switching power supply, ie the output voltage of the current transformer SW.
  • the voltages UA and UE are decoupled from one another, for example in the case of a switching power supply, and the invention can be carried out with a low input voltage UE.
  • the charging of the output capacitor CA is carried out at a working point on the connecting line of the points 11, depending on the current transformer output power currently available. 111, 211, 311 started. The choice of the working point on this connecting line ensures optimal rapid

Abstract

L'invention concerne un circuit d'alimentation en énergie de déclencheurs électroniques à partir d'un transformateur de courant (SW). Une alimentation à découpage (SNT), notamment un transformateur élévateur de tension continue (DR) comprenant un dispositif de régulation de tension en largeur de tension (PW), est implantée en aval du condensateur de charge (CL). Lorsque l'on atteint la valeur de consigne de tension de sortie (UA) au niveau d'un condensateur de sortie (CA), on obtient un rapport impulsion/pause très élevé. Notamment une commande du point de puissance maximale (MPP) permet de commander le modulateur en largeur d'impulsion dans la phase de démarrage de charge du condensateur de sortie (CA). Ces circuits sont utilisés pour alimenter en énergie des déclencheurs à maximum de courant des appareils à basse et moyenne tension.
