Definitions

  • the invention relates to a high-voltage rotary switch separating under load according to the preamble of claim 1.
  • the object of the invention is to design the high-voltage rotary switch separating under load of the type mentioned in the preamble of claim 1 in such a way that it reliably fulfills its switching function even at lower gas pressure, for example at 1.0 bar.
  • the object is achieved according to the invention by the training specified in the characterizing part of claim 1.
  • 1 denotes a housing that contains electronegative gas, for example SF 6 , and consists of metal or plastic.
  • the housing 1 is penetrated by a control shaft 2, which is rotatable by a drive, not shown, which is located outside the housing 1.
  • a switch blade 3 is fastened on the control shaft 2, which can be pivoted on and off by a corresponding rotation of the control shaft 2 from a position indicated by dash-dotted lines - off - into a position drawn with full lines.
  • the switching knife 3 and the mating contact piece 4 engage in a tube section 5 which is arranged in a stationary manner in the housing 1 and is curved around the switching shaft 2.
  • the tube section 5 has a slot 6 for the engagement of the mating contact piece 4 and is formed on the side opposite the slot 6 so that the switching knife 3 can describe the path determined for it.
  • the tube section 5 is tapered approximately in the shape of a nozzle in the region of the counter-contact piece 4, as shown. At least the nozzle-shaped part of the tube section 5 expediently consists of arc-proof plastic, for example polytetrafluoroethylene.
  • a displacer 7 designed as a piston is guided in the tube section 5.
  • the displacer 7 can be moved when the switching knife 3 is moved from its position - on - into its position - off - to the switching knife 3.
  • the tracking takes place in such a way that by the displacer member 7 in the pipe section 5, a gas flow is generated, which acts on the switching path between the mating contact piece 4 and the switching knife 5.
  • the displacement of the displacement member 7 is also carried out in such a way that the gas flow is still present for a short time even when the switch blade 3 has already come to a standstill in its off position.
  • the displacement member 7 tracks the switching knife 5 by means of a spring force accumulator 8.
  • the spring force accumulator 8 can be charged by the control shaft 2 or by the switch blade 3. It is designed and arranged in such a way that it first gives the displacement element 7 a hesitation in the switching knife 3, then accelerates the following movement, which only comes to a standstill after the switching knife 3 has come to a standstill.
  • a rocker arm 9 is pivotably mounted on the selector shaft 1 for tracking the displacement member 7 by the spring force accumulator 8.
  • the rocker arm 9 extends through a longitudinal slot 10 of the pipe section 5 and carries the displacement member 7 at its free end.
  • the spring force 8 acts on the one hand on the switching knife 3 and on the other hand on the rocker arm 9 and in the example shown consists of a helical spring.
  • the rocker arm 9 mounted on the control shaft 2 initially stops due to its inertia, the inertia of the displacement element 7 connected to it and the friction between the control shaft 2 and rocker arm 9 .
  • the coil spring used as the spring force accumulator 8 becomes tensioned by the switch blade 3. If the tension of the spring exceeds the sum of the inertial forces and the friction, the rocker arm 9 together with the displacement member 7 starts to move. Due to the progressive movement of the switch blade 3, however, the tension in the spring force accumulator 8 remains.
  • the displacer 7 displaces the gas column located in the pipe section 5 in front of it in the direction of the switching path formed between the counter-contact piece 4 and the switching knife 3 when switching off.
  • a pneumatically acting device can also be used, for example, which consists of a cylinder pivotally attached to the rocker arm 9 and a double-acting piston engaging in the cylinder, which is coupled to the switching knife 3 via a rod engaging it.
  • the gas of the cylinder space facing the switching knife 3 acts on the rocker arm 9, like the helical spring described above (not shown).
  • the spring force accumulator 8 can also consist of a torsion spring extending between the rocker arm 9 and the selector shaft 2.
  • the movement emanating from the control shaft 2 is in this case transmitted by the torsion spring to the rocker arm 9 in the same way as in the case of the screw described above benfeder.
  • a check valve 11 is expediently arranged in the displacer 7, which closes with each pivoting movement of the switching blade 3 into the position - off - and opens when the switching blade 3 is pivoted in the opposite direction.
  • the spring force accumulator 8 only has the function of a coupling, in which the spring force also builds up and breaks down for a certain movement sequence of the displacement member 7 is not important.
