Definitions

  • the invention relates to an arrangement and a method for switching high currents in high-voltage technology for a pole, with at least one first and at least one second contact.
  • a contact has at least two contact pieces, which are in electrical and/or mechanical contact with one another in the closed switching state.
  • the at least one first contact is arranged in a first housing and the at least one second contact is arranged in a second housing.
  • a high-voltage circuit breaker includes two contacts, a first and a second contact, each with two contact pieces.
  • the first contact is arranged as the main switching point in an insulating housing.
  • the second contact is connected in series with a resistor as an auxiliary switching point and is arranged together with the resistor in an insulating housing.
  • the resistor is used as an on-resistance when switching. If both contacts are open, the second contact with resistance, ie the auxiliary switching point, is initially closed, while the first contact, ie the main switching point, is open. The current flow via the auxiliary switching point is limited via the resistor.
  • the auxiliary switching point When the main switching point is closed, the auxiliary switching point is bridged and the current essentially flows via the main switching point, which is designed as a rated current contact.
  • Rated current contact also means that the contact is designed to carry large currents. It is possible to limit the current intensity via the auxiliary switching point using the resistor in series with the auxiliary switching point the design of the auxiliary switching point for low currents. This means that smaller diameters of the contact pieces of the auxiliary switching point and thus smaller masses can be used, which can be accelerated more easily and therefore switched more quickly compared to rated current contacts.
  • Analogous to high-voltage circuit breakers with arcing and rated current contacts when switched on, current flows essentially via the rated current contact, and the auxiliary switching point connected in series with the resistor serves to reduce arcing during the switching process.
  • the first contact ie the rated current contact, is always switched when the second contact is closed, ie when the auxiliary switching point is closed.
  • the maximum current flow across the arrangements for switching high currents, and thus the switching capacity of the high-voltage circuit breaker, is essentially determined by the rated current contact.
  • the second contact has resistance, i.e. H. the auxiliary switching point, through the first contact, i.e. H. the rated current contact, bridged.
  • An increase in the maximum current flow and the maximum voltage to be switched of the high-voltage circuit breaker are essentially limited by the design options for the rated current contact.
  • the object of the present invention is to provide an arrangement and a method for switching high currents in high-voltage technology.
  • it is the task of simply and cost-effectively increasing the maximum current flow and/or the maximum voltage to be switched compared to switching arrangements which are known from the prior art.
  • An arrangement according to the invention for switching high currents in high-voltage technology for a pole comprises at least one first and at least one second contact, with one contact having at least two contact pieces.
  • the two contact pieces are in electrical and/or mechanical contact with one another in the closed switching state.
  • the at least one first contact is arranged in a first housing and the at least one second contact is arranged in a second housing.
  • the at least one first and the at least one second contact are each rated current contacts, i.e. H.
  • the contacts are designed as contacts with high current-carrying capacity, especially for short-circuit currents in the range greater than 1 to 100 kA, with switching voltages up to 1200 kV.
  • the at least one first and the at least one second contact are connected in parallel to one another.
  • the at least one second rated current contact When switching the at least one first rated current contact, the at least one second rated current contact is always in the open switching state.
  • Auxiliary gears are included in the first and/or second rated current contacts in order to drive different movable contact pieces of a rated current contact, with different movement profiles.
  • the design of the parallel-connected, at least two contacts as rated current contacts enables an increase in the maximum possible current compared to known switching arrangements from the prior art, in which only one rated current contact is used per pole and in which arcing or auxiliary switching points are used, which are connected in series with a resistor and which only have a lower current carrying capacity.
  • the switching sequence, with at least one second rated current contact open when switching the at least one first rated current contact enables a simple design of the at least one second rated current contact without a blowing nozzle for extinguishing arcs and/or without arcing contacts.
  • the arrangement for switching can therefore be constructed simply and cost-effectively, and enables switching with little effort and high switching speeds.
  • Each of the first and/or the second housings can comprise an insulator, in particular an externally ribbed insulator made of silicone and/or ceramic.
  • a second rated current contact can be arranged in the second insulator housing, instead of auxiliary switching point and series-connected resistors in the second insulator housing.
  • the arrangement can be T-shaped and comprise a common, electrically insulating support column, in particular with a switching rod movably arranged inside the support column and/or kinematically connected, in particular with a common drive.
  • the T-shaped arrangement can comprise two, in particular tubular, pairs of insulators arranged essentially perpendicular to the support column in opposite directions, with the insulators of a pair being arranged essentially parallel to one another, in particular with the respective longitudinal axis.
  • Each insulator can each include at least one rated current contact. This results in at least two pairs of rated current contacts connected in parallel, with each pair having two in each Rated current contacts connected in series.
  • the parallel connection of the rated current contacts increases the current carrying capacity of the arrangement and the series connection of the rated current contacts within a pair increases the switchable voltage of the arrangement compared to a single rated current contact of the same design.
  • the result is a cost-effective, simple structure of the arrangement with high current carrying capacity and high switching voltage or dielectric strength in the open switching state.
  • the rated current contacts can be kinematically coupled to one another via at least one gear for converting and transmitting the switching movement, with switching of the second rated current contact when the associated first rated current contact is open.
  • the transmission can transmit a switching movement, provided by a common drive, to the at least one first rated current contact, and with a time delay to the at least one second rated current contact.
  • the transmission, provided by a common drive can transmit a switching-off movement to the at least one second rated current contact, and with a time delay to the at least one first rated current contact.
  • a main and secondary gear can also be used, in particular each arranged between two series-connected rated current contacts, for transmitting a switching movement with delay to parallel-connected rated current contact pairs. This enables a compact, simple and cost-effective switching arrangement.
  • the arrangement can be designed to switch direct and/or alternating voltages, in particular up to 1200 kV.
  • At least one arcing contact can be assigned to at least one, in particular all, rated current contacts, and/or At least one blowing nozzle can be assigned to at least one, in particular all, rated current contacts. All contacts can have a blowing nozzle and/or an arcing contact, whereby a very high power to be switched or very high currents and/or voltages to be switched can be achieved, with the possibility of extinguishing arcs that arise on each contact.
  • a pair of rated current contacts can also be assigned a blowing nozzle and/or an arcing contact, and another pair of rated current contacts can be designed without an assigned blowing nozzle and/or without an assigned arcing contact.
  • rated current contacts can be included in the arrangement for switching, with two first rated current contacts, which include a blowing nozzle on the respective rated current contact, and two second rated current contacts, which are designed without a blowing nozzle.
  • the current flow via the second rated current contact can correspond to 20 to 90%, in particular 50%, of the current flow via the first rated current contact. This enables a high current-carrying capacity of the arrangement as a whole, with the need for a blowing nozzle and an arc contact being dispensed with, particularly in the case of a second contact.
  • the rated current contacts can each consist of two contact pieces, in particular two hollow cylindrical contact pieces with a diameter of 50 to 200 mm, in particular 80 to 150 mm.
  • the contact pieces can consist of a highly conductive metal, in particular copper, aluminum or steel.
  • the contact surfaces of the contact pieces can be silver-plated and/or include carbon. This allows a high current to flow through the arrangement with little loss, ie with low resistance via contacts when the arrangement is switched on. This ensures a high current carrying capacity with a simple, cost-effective design of the arrangement.
  • the arrangement can be comprised of a three-pole switchgear, in particular with a previously described arrangement per pole.
  • the three-pole switchgear can have a previously described arrangement for each pole, with the advantages described above for each pole.
  • a method for switching direct and/or alternating current in high-voltage technology comprises that at least a first rated current contact in a first housing is switched on in front of at least a second rated current contact in a second housing and/or that at least a first rated current contact in a first housing is switched off after at least a second rated current contact in a second housing.
  • Two first rated current contacts with each of the two first rated current contacts in a respective first housing, can in particular be switched on simultaneously, before switching on two second rated current contacts, with each of the two second rated current contacts in a respective second housing.
  • the two first rated current contacts, with each of the two first rated current contacts in a respective first housing, can in particular be switched off simultaneously, after switching off the two second rated current contacts, with each of the two second rated current contacts in a respective second housing.
