  • Field of the Invention relates to a means for interrupting'high-voltage direct current.
  • the circuit interrupting means is preferably intended to be used as a load switch, that is, a switch for interrupting current during normal operation, but with special dimensioning it may also be used for interrupting short-circuit currents.
  • the object of the present invention is to provide a circuit interrupting means for high-voltage direct current, which, to the greatest possible extent, is built up of a-c devicesalready in existence. This is achieved by having a switch arranged in parallel with a series connection of a capacitor and a spark gap and with a surge diverter, this unit being in series, with a second switch. The surge diverter takes over the current and breaks it upon a breaking operation whereupon the second switch is opened to isolate the circuit.
  • a device of this design shows both lower cost of production and lower cost of development than the previously known circuit interrupting means for the same purpose.
  • the circuit interrupting means shown comprises equipment for commutating, interrupting and insulating.
  • the equipment for commutating consists of a socalled commutating circuit breaker 1 which is connected in parallel with a capacitor 2 through a'spark gap 3.
  • the equipment for interrupting consists of a surge diverter 4, and the equipment for insulating con sists of an isolator 5.
  • the circuit breaker l is opened, said circuit breaker thus generatingan arc voltage which ignites the spark gap 3. In this way, the current is rapidly transmitted to the capacitor 2, the are in the circuit breaker 1 thus becoming extinguished.
  • the voltage across the capacitor has reached the ignition level of the surge diverter 4, the latter is ignited, takes over the current and forces it in a controlled manner towards zero, that is, it interrupts the current without giving rise to unallowable overvoltages.
  • the isolator 5 opens and isolates the circuit.
  • the proposed circuit interrupting means differs from other commutating interrupting means by placing the function of interruption wholly on the surge diverter 4, whereas the purpose of the other components 1, 2 and 3 is only to activate the diverter and transmit the current to said diverter. In this way, the device can be built up from a relatively small number of components which, moreover, do not involve exceptionally high expense.
  • the surge diverter 4 consists of a resistor, preferably of voltage-depending type, connected in series with a self-extinguishing spark gap.
  • a design of such a surge diverter which is suitable for the purpose is described in U.S. Pat. No. 3,566,197.
  • Such a surge diverter consists-of a plurality of branches connected in parallel and comprising non-linear resistors and spark gaps providing arc extension by magnetic blow-out coils, and cross-impedances arranged between the branches for controlled transmission of ignition pulses between the branches.
  • the surge diverter branches and the crossimpedances are so dimensioned and arranged that a permanent ignition and extinguishing of the arc takes place in all branches, so that the current is permanently moved from one branch to another until it is finally interrupted.
  • Surge diverters of this type with the required breaking capacity are available on the market. Only a special adaption of the discharge voltage to the purpose in question is required, so that the recovery voltage after extinguishing does not exceed the spark-over voltage of the diverter, that is, does not ignite the diverter anew.
  • a conventional a-c circuit breaker of low oil content type (with the required number of breaking elements) may be advantageously used as commutating circuit breaker, since this type of circuit breaker has proved to be able to build up a relatively high are voltage. In addition to this, it is possible to derive advantage from the very rapid rebuilding of the dielectric strength, typical of breaking gaps in oil, when the arc is extinguished.
  • the isolator 5 should be high-speed-operated and arranged to open simultaneously with or immediately after the opening of the commutating circuit breaker 1. In this way, the required insulating distance across the circuit interrupting means is rapidly achieved, and the risk of external overvoltages causing restrike or flashover in any of the components 2, 3 and 4 is eliminated, said components being suitably designed for a relatively low insulating level in order to reduce the cost.
  • circuit breakers l and 5 do not necessarily have to consist of separate switching devices of different designs, but these circuit breakers could be built together to one unit containing breaking elements of one and the same type.
  • a device for interrupting high-voltage direct current comprising first and second electrical switching devices (1,5) connected in series, the first switching device (l) constituting a commutating circuit breaker, a series connection of a spark gap (3) and a capacitor (2) connected in parallel with the first switching device (1), and a surge diverter (4) connected in parallel with said first switching device, whereby said surge diverter takes over the current upon opening of said firstswitching device to break the current, whereupon said second switching device is opened.
