  • the present invention relates to an interrupter device for high voltage high intensity direct current, especially for the purpose of interrupting lines in a direct current supply system.
  • interrupter device will be employed hereinafter and in the appended claims to designate the entirety of components and circuits placed in a direct current line capableof being interrupted; the term embraces not only the actual interrupter items (for example, circuit-breakers) but also the associated electrical elements such as capacitors, resistances and circuits linking said elements.
  • an interrupter device for high voltage high intensity direct current comprising a main circuit containing, in series, a first terminal, a plurality of resistances, a final switching element located between two of the said resistances, and a second terminal, a transfer switching element being associated with each said resistance and being connected to said main circuit on opposite sides of the pertaining resistance, and a capacitor to assist the transfer is associated with at least certain of the transfer switching elements, each said capacitor being connected at two points on the 'main circuit which are situated one at each side of the associated transfer switching element "and the final switchingelement, the arrangement being such that on successively opening said transfer switching elements successively'to insert said resistances the switching overvoltages arereduced.
  • FIG. 1 shows the circuit diagram of a-first form of interrupter device according to the present invention
  • FIG. 2 shows a modified version of the circuit diagram of FIG. 1
  • FIG. 3 is a diagram showing the voltages taken at the terminals of an interrupter device according to the invention, for example those shown in FIGS. 1 and 2, and
  • FIG. 4 illustrates the circuit diagram of a further form a of interrupter device according to the present invention.
  • the interrupter device for interrupting a direct current line 2 2 between two terminals 4, 6 comprises a main circuit containing, in series between the two terminals 4, 6 a first resistance R a final switching element or circuit-breaker D and a second resistance R the final circuit breaker D being placed between the two resistances and not at the end of the circuit as has been the practice hitherto.
  • the reistances R R are preferably of non-linear type R being greater in value than R,.
  • the first resistance R is connected in parallel with a first transfer switching element or transfer circuitbreaker D whilst the second resistance R is connected in parallel with a second transfer circuit-breaker D
  • a capacitor C C to assist the transfer is connected in parallel with each transfer'circuit-breaker D D but, instead of being simply connected to the terminals of the circuit-breaker with which it is associated, each capacitor is connected at two points on the main circuit which are situated one on each side of the associated transfer circuit-breaker and the final circuit-breaker D
  • the first capacitor C has one terminal connected to the point 8 on the main circuit beyond D whilst the second capacitor C2 has one terminal connected to the point 10 before D (the assumed direcn ofs ysm bein sho n t e arrow When the line 2 2 is operational the three circuitbreakers D, D D are closed.
  • D, D D areopened in turn.
  • the resistance R is brought intothe circuit, this first intermediate switching operation being assisted by the presence of the capacitorC
  • the second resistance R is brought into the main circuit, this second intermediate switching operation being assisted by the presence of the capacitor C
  • the two capacitors C, and C are in parallel, and, furthermore, each is'in series with a resistance (C with R and C with R,), which substantially limits voltage oscillations or absorbs these very rapidly after the final switching operation (see point 14 in FIG. 3).
  • the capacitors serve a double purpose, that is to say, they assist the intermediate switching operations and they absorb the residual energy which, after the insertion of the last resistance, is absorbed partly by the set of capacitors and partly by the resistances.
  • FIG. 3 shows the variations in voltage U at the terminals 4 6 of the device in relation to time at themoment of the breaking of current in the device shown in FIG. I.
  • the device illustrated in FIG. 1 has the disadvantage that the entire current passes through the three circuitbreakers D, D D when the line is operational. That is why it is preferable according to the modification shown in FIG. 2, to move the output connection of the first circuit-breaker D to the output terminal 6 of the device.
  • the current when the line is operational, the current only passes along the part of the device shown in thick lines, that is to say the circuitbreaker D whilst the circuit-breakers D and D are not subjected to the permanent current. Apart from that, the device functions in identical manner to that described with reference to FIGS. 1 and 3.
  • the device according to the invention is applicable irrespective of the number of switching stages involved, that is to say of the number of resistances inserted.
  • Such a device is illustrated by way of example in FIG. 4.
  • the break in current is effected by the successive insertion of four resistances which preferably are non-linear.
  • the main circuit comprises, in series between the terminals 4 and 6, four resistances R R R R and the final circuit-breaker D which is located between two of these resistances, for example R and R
  • Each resistance is connected in parallel with a transfer circuitbreaker D,, D D D and a capacitor to assist the transfer is associated with each transfer circuitbreaker, the connection being so arranged that each capacitor is connected at two points situated one on each side of the associated transfer circuit-breaker and the final circuit-breaker D
  • the capacitor C associated with the circuit-breaker D is connected on the one hand to the terminal before D and, on the other hand, to a point below D and between R, and R
  • the sequence of operations is identical to that described with reference to FIGS.
  • the invention consists in effecting successive breaks in the course of which the energy is transferred to a series of resistances, each intermediate transfer break being provided with a switching capacitor to assist in breaking the current.
  • the disposition of the switching or interrupter elements, resistances and capacitors is such that, at the moment of the final break, the entirety of capacitors and resistances is utilised to absorb the residual energy; in other words, the capacitors, which are expensive items of plant where high voltages and capacitances are involved, are efficiently utilised.
  • the residual magnetising energy is absorbed partly by the set of capacitors and partly by the resistances; secondly, since each capacitor is in series with a resistance the voltage oscillations after the final break are nil, or at least are very rapidly absorbed. Furthermore, the energetic potential of the capacitors is utilised to the maximum since, at the moment of the final break, these are all in parallel and subjected to the full switching overvoltage, and the value of the resistance associated with each capacitor may, to a certain extent, be selected in order to utilise efficiently the energetic capacitance of the capacitor.
  • An interrupter device for high voltage high intensity direct current comprising a main circuit containing, in series, a first terminal, a plurality of resistances, a final switching element located between two of the said resistances, and a second terminal, a transfer switching element being associated with each said resistance and being connected to said main circuit on opposite sides of the pertaining resistance, and a capacitor to assist the transfer is associated with at least certain of the transfer switching elements, each said capacitor being connected at two points on the main circuit which are situated one at each side of the associated transfer switching element and the final switching element, the arrangement being such that on successively opening said transfer switching elements successively to'insert said resistances the switching overvoltages are reduced.
