Definitions

  • switches are preferably used that switch themselves gas-free, e.g. Semiconductor switches, varistors, vacuum switches, thermistors used. These switches can also be combined with one another and / or with mechanical load switches, preferably in parallel.
  • the first switch can be formed by a parallel connection of a mechanical load switch with a vacuum switch or by a parallel connection of a varistor with a vacuum switch.
  • the first switch is preferably or contains a vacuum switch.
  • Vacuum switches have proven themselves as gas-free and reliable switching elements in the power range. They can also be placed in an oil bath together with a power transformer. As a rule, these vacuum switches are designed as vacuum interrupters.
  • the first switch can preferably be formed by a diode circuit or contain a diode circuit. This is particularly advantageous for circuits in which the AC voltage is switched at the zero crossing.
  • the first bridge switch 20 and the third bridge switch 24 are opened, whereby the preselector 28 is only connected to the main winding 12 via the closed vacuum switch 38, but the polarity resistor 34 connected to the center tap 36 of the control winding 14 is connected directly via the second bridge switch 22.
  • the vacuum switch 38 is closed, which means that the second end 32 of the control winding 14 is now connected to the main winding 12 via the preselector 28, the closed fourth bridge switch 26 and also via the closed vacuum switch 38. Since this connection through the Vacuum switch 38 is realized, this switching process also takes place without the generation of an arc and thus gas-free.
  • the second bridge switch 22 is now opened again, so that the polarity resistor 34 is only connected to the main winding 12 via the closed vacuum switch 38.
  • the vacuum switch 38 is opened, as in FIG. 1l is shown.
  • the polarity resistor 34 is separated from the main winding 12.
  • the control winding 14 is thus only connected at its second end 32 to the main winding 12 via the preselector 28 and the first bridge switch 20, as is the desired changeover position of the preselector.
  • the third bridge switch 24 is still open, so that in turn the starting position according to FIG. 1a is reached, with the difference that the main winding 12 is now connected via the preselector 28 to the second end 32 of the control winding 14 instead of to the first end 30 of the control winding 14 before the switching process.
  • FIG. 5a shows as the first switch a vacuum switch 76, for example a vacuum interrupter known per se.
  • the advantage of this switch lies in the encapsulated and thus gas-free switching, so that the switching operations of the first switch 74 in connection with the switching operation of the preselector also run gas-free.
  • FIG. 5d a switching arrangement 92 consisting of a series connection of a first selector switch 94, a parallel connection of two diodes 96, 98 connected in opposite directions and a conductor 100 and an additional switch 102.
  • the selector switch can optionally switch to one of the two diodes 96, 98 or to the conductor.
  • the start time for the switching of the diodes 96, 98 can be set via the additional switch 102. It is therefore possible to switch to zero gas when the AC voltage crosses.
  • FIG. 6 shows a preselector 104, which can be arranged, for example, coaxially with a fine selector or load selector.
  • the switching configuration of the preselector 104 is on FIG. 4 (Wender 66) referenced.
  • the two switch contacts 70, 72 connected to the ends of the control winding are arranged stationary.
  • the preselector 104 contains a switching group 106 which can be moved in / against the direction of the arrow and has three switching elements S1, S0 and S2, which interact with the stationary switching contacts 70, 72.
  • the two outer switching elements S1 and S2 are connected via a vacuum switch 108 to the middle switching contact S0, which in turn is connected to the tap 68 of the preselector 104. This is connected directly or via a first switch 74 to the main winding 62.
