Definitions

  • the invention is based on a multi-phase electrical power distribution network according to the preamble of claim 1:
  • a high voltage operated, three-phase power distribution network is known.
  • This power distribution network has overhead lines connecting various substations and consumers.
  • circuit breakers are provided, which among other things serve to protect the cables and consumers against consequential damage caused by a short circuit. These circuit breakers selectively switch off the faulty areas of the power distribution network in the event of damage.
  • a commercial circuit breaker usually dominates the switching cases occurring in the power distribution network.
  • the power distribution network has a comparatively high short-circuit power with fault currents in the range above about 40 kA to 50 kA, then it is possible that the commercial circuit breaker not master the special case of the short-circuit in each case safe.
  • each of the capacitors has an insulation path to ground that must be serviced, thereby incurring additional costs, and the time required for this maintenance somewhat limits the availability of the power distribution network.
  • the installation of additional capacitors can change the natural frequency of the power distribution network so that ferron resonances are possible. Due to these ferroresonances undesired overvoltages can occur during switching operations in the network.
  • the invention solves the problem of providing a multi-phase power distribution network in which no additional capacitors for the reduction of the system-related slope of the recurrent voltage are needed.
  • a hybrid circuit breaker according to the preamble of claim 1 is provided.
  • the advantages achieved by the invention can be seen in the fact that the additional capacitors omitted, whereby the space required for the substations of the power distribution network is reduced, so that the construction costs for the creation of the power distribution network are advantageously reduced.
  • these capacitors also eliminates the additional insulating bridged distances and thus the cost of the regular cleaning of this isolation. With the elimination of the additional capacitors and the risk of the occurrence of unwanted Ferroresonanzen is banned in the power distribution network.
  • FIG. 1 shows a greatly simplified single-phase equivalent circuit diagram of a conventionally constructed power distribution network 1.
  • the usually always existing shear separator, earth electrode and transducer are not shown, as well as the energy generator.
  • This power distribution network 1 has a high-voltage part 2 lying at potential and a grounded part 3. Between an arranged in the high voltage part 2 terminal 4 and arranged in grounded part 3 terminal 5, a resistor 6 is connected in series with a capacitor 7.
  • the resistor 6 represents the ohmic portion of the network impedance, the capacitor 7 represents the capacitive component of the network impedance, and the terminal 4 upstream Inductance 8 represents the inductive component of the network impedance.
  • From the terminal 4 is an overhead line 9 from. At the beginning of this overhead line 9, as well as at the other end, not shown, a circuit breaker 10 is provided, these two circuit breaker switch off the overhead line 9 in case of failure.
  • a terminal 11 is provided. Between this terminal 11 and a terminal 12 arranged in the earthed terminal 12, an additional capacitor 13 is connected. A similar additional capacitor is also provided at the other end of the overhead line 9. If, for example, triggered by a lightning strike, a ground fault 15 occurs in a fault location 14, the two circuit breakers must switch off the overhead line 9. If the fault location 14 is comparatively close to the power switch 10, ie in the region in which, referred to this circuit breaker 10, the occurrence of a distance short circuit can be spoken, then the slope of the rise of the recurrent voltage is limited to such values by the additional capacitor 13, which can control the circuit breaker 10 properly. The traveling wave processes caused by the short-circuit on the length of the overhead line 9 between the circuit breaker 10 and the fault location 14 can then cause no disturbance.
  • FIG. 2 shows a greatly simplified, single-phase equivalent circuit diagram of a power distribution network 1 constructed in a simplified manner according to the invention.
  • the shearing separators, earth electrodes and measuring transducers, which are generally always present, are not shown, nor are the energy generators.
  • This power distribution network 1 has a high-voltage part 2 lying at potential and a grounded part 3. Between a arranged in the high-voltage part 2 terminal 4 and arranged in grounded part 3 terminal 5 is an ohmic Resistor 6 connected in series with a capacitor 7.
  • the resistor 6 represents the resistive component of the network impedance, the capacitor 7 represents the capacitive component of the network impedance, and the terminal 4 upstream inductance 8 represents the inductive component of the network impedance. From the terminal 4 is an overhead line 9 from.
  • a hybrid circuit breaker 16 is provided, these two hybrid circuit breaker switch off the overhead line 9 in case of failure. If, for example, triggered by a lightning strike, an earth fault 15 occurs in a fault location 14, the two hybrid circuit breakers switch off the overhead line 9 properly. They switch off the overhead line 9 even in case of error "distance short circuit" problem-free, since they dominate all possible in power distribution networks 1 steepnesses of the increase in the recurring voltage. Capacitors for reducing the increase in the recurrent voltage are therefore not necessary here.
  • the hybrid circuit breaker 16 has in a preferred embodiment, two series-connected switching chambers 17 and 18, of which the first switching chamber 17 is formed as filled with an insulating gas chamber, while the second switching chamber 18 is formed as a vacuum interrupter chamber.
  • the first switching chamber 17 is designed for permanent control of high holding voltages (operating voltages).
  • the second switching chamber 18 is designed for the control of relatively high initial slopes of the recurring voltage, it takes over in the period shortly after the extinction of the Ausschaltlichtbogens the comparatively large slope of the increase in the recurrent voltage. During this period, the switching path of the first switching chamber 17 is further blown and cleaned of conductive switching residues, so that thereafter a sufficient reached dielectric strength to withstand the further increase of the recurring voltage and then the operating voltage.
  • the hybrid power switch 16 is also provided with an effective voltage control, which ensures that neither of the two switching chambers 17 and 18 is dielectrically overloaded during the turn-off operation and during normal operation.
  • the elimination of the additional capacitors has the great advantage that the natural frequency of the power distribution network is with great certainty far enough away from the area in which harmful Ferroresonanzen can occur.
  • the reliability and availability of the power distribution network is thereby advantageously increased.
