Definitions

  • the invention relates to a hybrid circuit breaker for disconnecting a network branch, in particular for extremely current-limiting disconnection in the event of short circuits.
  • the forward losses of bipolar semiconductors due to the forward voltage of, for example, typically 1.5 V for the thyristor and 2.5 V for the thyristor that can be switched off are up to two orders of magnitude higher than in the mechanical switch.
  • unipolar semiconductors such as, for example, MOS transistors
  • there is no pn junction in the main current path so that the forward resistance can in principle be reduced as desired by increasing the area.
  • Semiconductor switches are used in practice for use as a fault current limiter (see IEEE Transactions on Power Delivery, Vol. 5, No. A (1990), p. 1830 to 1838).
  • the object of the invention is to design a bipolar semiconductor switch with which network branches can be safely switched on and off and in which An extremely current-limiting cut-off is ensured in particular in the event of a short circuit.
  • the object is achieved by the parallel connection of a fast mechanical switch and a thyristor.
  • the fast mechanical switch preferably has a so-called Thomson drive.
  • the thyristor can preferably be switched off and in particular a so-called GT0 (gate turn off).
  • the basic idea of the switching arrangement according to the invention is that the mechanical switch only has to carry the nominal current or operationally permissible overcurrent, but not short-circuit currents. If a possible short circuit is suspected, the GTO is ignited and the mechanical switch with a Thomson drive is opened. A small tear-off spark is formed and the switching path is solidified again in the shortest possible time. If the suspicion of a short circuit has been confirmed, the GTO switches off. If there is no short circuit, the mechanical switch closes again. The loss of energy occurring at the GTO is negligible.

  • FIG. 2 the realization of a fast mechanical
  • FIG. 3 Switch in the closed and open state and FIG. 3 with partial figures a to d voltage curve and current distribution during a switch-off process of a switch according to FIG. 1 and FIG. Second
  • FIG. 1 denotes 1 a power supply unit
  • 2 denotes a capacitor of predetermined capacitance, for example 0.196 F
  • 3 denotes a semiconductor switch implemented as a thyristor
  • 4 denotes a consumer with predetermined ohmic and inductive resistance, for example 22 m and 42.5 ⁇ H.
  • Components 1 to 4 form a test circuit which largely corresponds to a real network branch, the test current being generated by the capacitor discharge by switching on the thyristor B. A wide variety of switching arrangements can be tested with such a test circuit.
  • a hybrid circuit breaker is specifically arranged as the switch to be tested. It consists in particular of the parallel connection of a GTO 10 ( ⁇ g_ate turn ff thyristor) and a fast mechanical switch 20.
  • a protective circuit 15 is assigned to the GTO 10. It consists in particular of the parallel connection of a diode 16 with a downstream capacitance 17 and an ohmic resistor 18. Such protective circuits are known as so-called snubber circuits.
  • a varistor 19 is connected in parallel to the GTO 10 for voltage limitation.
  • FIG. 2 is the fast mechanical switch 20 according to FIG. 1 shown in detail. It consists essentially of silver contacts 21 which are attached to leaf springs 22 and are pressed together by the latter. For example, the nominal switching capacity of such a Chen switch 25 A. In such fast switches, the contacts are separated by pressing the contacts 21 apart with a plunger 23 designed as a cutting edge, on which there is also an aluminum disk 24.

  • Sub-figure b shows the current at varistor 19, sub-figure c the current in mechanical switch 20 and sub-figure d the current in GTO 10.
  • the time deflection was measured at 50 ⁇ s / div, the voltage at the hybrid circuit breaker in accordance with FIG. 3a with 100 V / div, the current in the varistor 19 according to FIG. 3b, the current in the mechanical switch 20 according to FIG. 3c with 20 A / div and the current in the GTO 10 according to FIG. 3c selected with 20 A / div.
  • the curve shape shown in this way is significant for the on the basis of FIG. 1 and FIG. 2 described hybrid circuit breakers 10, 20.
  • Switching off the GTO's 10 typically takes 8 ⁇ s. However, the GTO branch continues to conduct since the current commutates in the snubber circuit 15, where it charges the capacitor 17 and thus builds up a voltage. The maximum voltage is 250 V and results in a current that has subsided after approx. 150 ⁇ s.

Abstract

De tels sectionneurs de puissance doivent pouvoir interrompre le courant passant par un branchement sur le réseau et notamment permettre une coupure limitant extrêmement le courant lors de courts-circuits. A cet effet, un commutateur magnétique rapide (20) est connecté en parallèle à un thyristor (10). Le commutateur mécanique rapide (20) a un circuit d'attaque dit de Thomson (25) et le thyristor, notamment un thyristor (10) blocable par la gâchette, peut être mis hors-circuit.
