Definitions

  • the embodiments of the invention described here generally relate to a compressed gas switch, in particular for high or medium voltage.
  • DE 30 44 836 describes a compressed gas switch with two relatively movable contact pieces and with an insulating nozzle. If the two switching pieces separated from each other, a switching arc, which is to be extinguished as quickly as possible, to avoid undesirable high burnup of the switching pieces. In such a switch, the arc carries material from the insulating walls, thereby increasing the pressure so that heated gas drains into a compression chamber and can later be used as quenching gas.
  • the insulating nozzle allows the quenching gas to flow from the compression chamber into an expansion space to cool and thereby quench the switching arc.
  • the insulating nozzle has a ring-shaped insert embedded in a constriction (eg of conductive materials, in particular graphite or Teflon filled with conductive material, or of materials with a dielectric constant greater than 5), which is arranged electrically insulated from the two contact pieces. and with respect to the first contact piece has a first and compared to the second contact piece has a second capacitance.
  • the order and the dimensioning of the insert are chosen so that an electric field built up in the region of the constriction from the nozzle surface into the compression space and into the expansion space when a voltage is applied between the contact pieces is displaced.
  • EP 1 544 881 A1 also describes a compressed gas switch, in which an effect on the electric field is sought.
  • the compressed gas switch described therein has an insulation nozzle with a conductive part and an electrically insulating part, which surrounds the conductive part at least partially. On an inner surface of the insulating nozzle, the insulating member does not cover the conductive member. As a result, a more uniform distribution of the electric field is sought.
  • the switch includes a first arcing contact and a second arcing contact, wherein when the switch is turned on, the first arcing contact is with a contact region of the second arcing contact is in contact and movable to interrupt the switch of at least one of the arc contacts along an axis of the switch, and a Isolierstoffdüse which extends in the axial direction and the arc contacts and / or an arc extinguishing zone between the arc contacts surrounds and a nozzle line for blowing one when switching Furthermore, the insulating material nozzle in the region of the nozzle throat has a part which has at least one recess on its outer side facing away from the arc extinguishing zone, in which a field element is arranged, which serves to control an electric field between the arcing contacts.
  • the Isolierstoffdüse thus has on its outer side a recess or more recesses in which at least one field element is present, which serves during switching off to a control of the electric field between the arcing contacts. After the field element is introduced into the depression, the field element is not covered. As a result, problems in the conventional embedding of the field element in the insulating material nozzle are avoided and the manufacturability of the field-controlling insulating nozzle duetlich simplified and cheaper.
  • the at least one depression on the outside of the part extends annularly around the part of the insulating material nozzle.
  • the field element is present as a coating on a surface of the depression.
  • Various parameters such as the thickness of the layer or of the field element and the depth and width of the depression can be determined for a desired field control.
  • the field element is an annular body that extends along the recess.
  • the position and the size of the field element can for the desired Field control.
  • the annular body should be installable from the outside in the recess and consist of a conductive and / or dielectric material.
  • the nozzle may have more than one recess, wherein preferably each recess contains a field element.
  • the combination of recess and field element may be present on one or both nozzles.
  • the field element In the off state of the switch, the field element is also between the arcing contacts.
  • the field element may be a solid or hollow body.
  • a hollow body as a field element may have a closed or a non-closed contour.
  • the field element may also have a non-conductive (insulating) core that is completely or partially surrounded by a conductive layer.
  • the field element contains a material having a dielectric constant ⁇ >> 1, preferably ⁇ > 5 and in particular a ferroelectric.
  • FIG. 1 shows a first embodiment of the gas pressure switch 1 in the off (ie non-conductive) state.
  • the switch 1 has a first or outer arcing contact 2, typically an arcing contact tulip 2, which extends annularly about the axis A, and a second or inner arcing contact 3, typically an arcing contact pin 3, which is generally rod-shaped or tubular.
  • the outer contact 2 surrounds the inner contact 3 annularly.
  • the two arcing contacts 2, 3 are relative to each other in the axial direction by a mechanical drive not shown displaced.
  • the outer contact 2 is stationary, while the inner contact 3 is movable, for example, to the left.
  • a two-part switch body 4a, 4b arranged for the so-called rated current contacts 4a, 4b, the low-resistance contacts for provide the rated current with the switch closed.
  • the rated current contacts 4a, 4b essentially encompass the arcing contacts 2, 3, as seen from FIG. 1 seen. If the rated current contacts 4a, 4b are disconnected, the current commutates to the arcing contacts 2, 3. Subsequently, the arcing contacts 2, 3 are disconnected. This creates a current-carrying arc, which is extinguished by means of compressed gas.
  • the compressed gas is provided in a self-blow circuit breaker by the so-called Disblas bin, ie by self-heating in a heating volume and assisted by evaporating insulating material material, and in a buffer circuit breaker by a piston.
  • the pressurized gas is then directed from the insulating nozzle 5, 9 to the burning arc to achieve efficient blowing and arc quenching.
  • the insulating nozzle 5 of the switch 1 is typically attached to the switch body 4b.
  • the insulating material nozzle 5 is made, for example, of plastic, in particular PTFE, and has a tubular part 5a and a mouth part 5b.
  • the parts 5a, 5b often have substantially equal outer diameters but different inner diameters. How out FIG. 1 As can be seen, the inner diameter of the mouth part 5b decreases starting from the inner diameter of the part 5a to a minimum at a point M, in order to increase again from this point M in the direction of the arcing contact pin 3.
  • the tubular part 5a surrounds the arc contact tulip 2 annularly.
  • the mouth portion 5b projects beyond the contact tulip 2 so far that it penetrates in the on state in the switch body 4a and the Nennstromnapspe and the arc contact pin 3 surrounds annular.
  • the mouth part 5 b forms a constriction 6 in the region of the point M for a gas flowing out of an extinguishing chamber for extinguishing an arc between the contacts 2, 3.
  • the switch 1 has the Isolierstoffdüse 5 in the region of the mouth part 5b on an outer surface, ie, on an outer side facing away from the arc extinguishing zone, an annular recess 7.
  • a field element 8 is arranged, which serves for field control.
  • the field element 8 is applied by way of example as a layer on a surface of the recess 7.
  • the field element 8 can be made of a conductive material or of a material with a high dielectric constant ( ⁇ >> 1, preferably ⁇ > 5).
  • the thickness of the layer can be selected depending on the material and the field influence to be achieved.
  • the thickness may be, for example, about 3 mm.
  • the depth and width (width) of the recess 7, and thus its surface can be selected according to a field control to be achieved in the region of the insulating material nozzle 5, 9.
  • the field element 8 substantially covers the entire surface of the depression 7. The thickness and the surface are thus available as parameters in order to control the field influence to be achieved via the field element 8.
  • FIGS. 2-5 show various embodiments of the insulating material 5, wherein the insulating material 5 is shown together with the arc contacts 2, 3. To simplify the illustration, the nominal stator contacts 4a, 4b of the switch 1 are omitted.
  • the mouth part 5b of the insulating material nozzle 5 has at least one depression 7, the position, width and depth of which varies depending on the exemplary embodiment or the requirements of the field control.
  • an axial position of the recess 7 is selected near a transition between the tubular part 5a and the mouth part 5b.
  • the field element 8 is in the Recess 7 introduced and extends along the recess 7 in the circumferential direction around the mouth portion 5b.
  • the field element 8 generates a strong field control.
  • the field is moved to the right, ie in the direction of the second arcing contact 3.
  • the first arcing contact 2 and the area between the first arcing contact 2 and the rated current contact or switch body 4b is relieved.
  • the recess 7 is displaced in the axial direction of the arcing contact pin 3 and thus relatively far from the transition between the tubular part 5a and the mouth portion 5b of the insulating material 5 is arranged.
  • the recess 7 is wider, ie wider in the axial direction, and deeper, that is embedded in the radial direction deeper into the insulating material 5, as in the embodiment according to FIG. 2 ,
  • the field element 8 is introduced into the recess 7, z. B. einmontiert or clamped, but not covered from the outside and in particular not embedded in the insulating material 5.
  • the recess 7 is again arranged close to the transition between the tubular part 5a and the mouth part 5b.
  • the recess 7 is deeper in the radial direction than in FIG. 2 shown.
  • the field element 8 here displaces the field in the region of the arc extinguishing zone to the right and left. This is again advantageous for the Arc contact pin 3 when passing through said area.
  • the mouth part 5b has two recesses 7a, 7b.
  • the depression 7a is arranged axially closer to the arc contact tulip 2 and thus close to the transition between the tubular part 5a and the mouth part 5b.

  • the recess 7b is located axially closer to the arcing contact pin 3 and thus relatively far from the junction and has approximately the same parameters as in FIG FIG. 3 shown.
  • the field control takes place here as a combination of the in FIGS. 3 and 4 shown control mechanisms. In the area of the arc extinguishing zone in the insulating nozzle, the field is pushed out.
  • three or more depressions 7, 7 a, 7 b may be present and equipped with field control elements 8.
  • the field element 8 respectively in the designated recess 7, 7a, 7b used without the recess 7, 7a, 7b is closed. In terms of manufacturing technology, this is less expensive than the embedding of a field element in the material of the insulating material 5 known from the prior art.
  • the switch 1 additionally has an auxiliary nozzle 9, which extends substantially between the insulating material 5 and the first arcing contact 2 (arcing contact tulip 2).
  • the auxiliary nozzle 9 is for example made of plastic, in particular of PTFE, and also has a tubular part 9a and a mouth part 9b.

  • the field element 8 may be a solid or hollow body.
  • a hollow body as a field element 8 may have a closed or a non-closed contour. When the contour is not closed, the field element 8 has a concave area on the surface.
