Definitions

  • the invention relates to control of at least one vacuum switching path according to the preamble of claim 1.
  • the invention can be used, for example, in high-voltage devices, the term “high voltage” being understood to mean the voltage range above 1000 V.
  • the invention has for its object to provide a simplified control of at least one vacuum switching path.
  • 6a, 6b, 6c vacuum interrupters of different embodiments.
  • a vacuum switching path with control is shown schematically.
  • the vacuum switching path 1 vacuum chamber, main switching path
  • a first, schematically shown ohmic control resistor 3 is between the first main connection of the vacuum switching path 1 and the screen 2 arranged.
  • a second ohmic control resistor 4 lies between the second main connection of the vacuum switching path 1 and the screen 2.
  • a vacuum switching path with control and auxiliary switching path or isolating / load-break switching path is shown schematically.
  • the embodiment with vacuum switching path 1, screen 2 and ohmic control resistors 3, 4 is as described under Fig. 1.
  • a control device 6 is used for the time-coordinated control of vacuum switching path 1 and auxiliary switching path or isolating / load-isolating switching path 6.
  • a multi-gap vacuum switch with control and auxiliary switching path or isolating / load disconnecting switching path is shown schematically.
  • the multi-gap vacuum switch 7 has three vacuum switching paths 8, 9, 10 connected in series, an ohmic control resistor 11 or 12 or 13 being arranged in parallel with each vacuum switching path 8 or 9 or 10.
  • An auxiliary switching path or isolating / load-isolating switching path 14 is in series with the three vacuum switching paths.
  • a control device 15 is used for the time-coordinated control of vacuum switching paths 8, 9, 10 and auxiliary switching path or isolating / load-isolating switching path 14.
  • FIG. 4 shows a further embodiment of a multi-gap vacuum switch with control and auxiliary switching path or isolating / load-isolating switching path is shown schematically.
  • this embodiment of the multi-gap vacuum switch 16 three series-connected vacuum switching paths 17, 18 and 19 are provided, each having screens 20, 21 and 22 (screen electrodes).
  • a resistor is connected between each main connection of a vacuum switching path and a connection to a screen, so that there is a series connection of a total of six resistors 23, 24, 25, 26, 27, 28 parallel to the connections of the multi-gap vacuum switch 16.
  • An auxiliary switching path or isolating / load-separating switching path 29 is in series with the three vacuum switching paths.
  • a control device 30 serves for the coordinated control of vacuum switching paths 17, 18, 19 and auxiliary switching path or isolating / load-isolating switching path 29.
  • the general rule for the design of the vacuum switching paths is that they ensure current interruption - in particular short-circuit current interruption - and that they have to withstand the transient voltage.
  • the potential control is implemented via ohmic control resistors, these ohmic control resistors being arranged parallel to the vacuum switching paths and a significant reduction in the ground capacities due to the different capacities taxation that always occurs. It can thus be approximately achieved that the transient voltage present across the switching paths after the interruption of a current (short-circuit current) can be distributed evenly over these, which leads to a reduction in the maximum stress on a switching path.
  • the size of the ohmic control resistors must be such that the current flowing through them (parallel current to the main section) is at least in the order of magnitude of the capacitive displacement current flowing through the respective vacuum switching sections.
  • the capacitive displacement current depends on the sizes of the capacities and the change in the transient voltage over time.
  • the influence of the ohmic control resistors is greater, the smaller they are dimensioned, in other words the ohmic control has to be low enough to ensure a significantly more uniform distribution of the transient voltage across the main switching paths.
  • the ohmic control resistors can also be coupled to the screen of the vacuum chamber in order to also be able to control the potential of the screen, as can be seen from FIGS. 1, 2 and 4.
  • an auxiliary switching path or isolating / load-isolating switching path must be arranged in series with the main switching paths or control resistors, which interrupts this predominantly ohmic leakage current. Due to the size of the ohmic control resistors, however, the current to be interrupted is orders of magnitude smaller than a short-circuit current that may occur, so that the auxiliary switching path or isolating / load-isolating switching path is related to the one to be interrupted Electricity can be made much simpler.
  • the auxiliary switching section or isolating / load-disconnecting switching section not only represents a separating section for the ohmic control resistors, but also takes over the isolating function with regard to the vacuum switching sections. Therefore, the auxiliary switching path or isolating / load-isolating switching path must be able to carry both operating currents and short-circuit currents.
  • a circuit breaker or a load break switch can be used as the auxiliary switching path or isolating / load break switching path.
  • the requirement for the cold voltage strength (rated short-time AC voltage and rated short-time lightning impulse voltage) of the main switching paths can be significantly reduced.
  • the control devices 6, 15, 30 implement a time control in such a way that the auxiliary switching path or isolating / load disconnecting switching path opens shortly after the short-circuit current interruption (opening of the main switching paths) in order to prevent thermal overloading of the ohmic control resistors.
  • the ohmic control resistors can be realized as a conductive coating.
  • the coating can be partially or completely covering.
  • the layer thickness of the coating can be varied according to the application.
  • the ohmic control resistors can also be realized as a resistance fabric, whereby the resistance fabric can additionally be potted with an insulating material.
  • a resistance fabric can be produced, for example, by "weaving" a resistance wire onto an insulating tube.
  • the ohmic control resistors can be part of a pole part, for example as an inner R lacquer layer (resistance lacquer layer), furthermore they can be part of an outer shell (which controls the mechanical loads) or part of a fastening element for the vacuum chamber or the multi-gap Vacuum switch, for example a plastic threaded rod.
  • a pole part for example as an inner R lacquer layer (resistance lacquer layer)
  • an outer shell which controls the mechanical loads
  • a fastening element for the vacuum chamber or the multi-gap Vacuum switch for example a plastic threaded rod.
  • control devices 6, 15, 30 can be designed to be mechanically and electronically controlled.

  • each ohmic control resistor 33 or 34 is additionally connected in series with a separate auxiliary switching path 36 or 37.
  • the variant according to FIG. 5c corresponds to the variant according to FIG. 5b with the difference that the isolating / load-isolating switching path 35 is omitted.
