Definitions

  • the invention relates to an insulating gas filled high voltage circuit breaker with two opposing AbbrandCounten, which are surrounded by a Isolierstoffdüse, with two outside the insulating material facing each other main contacts, each of which is assigned to one of the two Abbrand tokene, and means for deriving a Isoliergasströmung from the area between the two burn-off contacts, one each Isoliergasströmung outside the insulating material is directed from both directions in the direction of the main power contacts.
  • Such high voltage circuit breakers are well known.
  • the means for diverting the Isoliergasströmung from the area between the two Abbrandnessen have the task to direct the heated by an arc and expanding insulating gas in other areas of the high voltage circuit breaker.
  • the hot insulating gas can not only relax in this way, but there is also a cooling of the hot insulating gas due to a mixture with cold insulating gas, which is present in the flow areas, as well as due to a heat transfer to the flow-through components of the high voltage circuit breaker.
  • Such a switch is eg from the document WO / 03096365 A known.
  • the requirement to use as little insulating gas has meant that the filled with insulating gas areas of the high voltage circuit breaker are getting smaller and at the same time, the density of the insulating gas is chosen to be lower and lower. This has the consequence that the two Isoliergasströmonne which are conducted outside the insulating material from both directions approximately along the longitudinal axis in the direction of the main current contacts, may no longer have sufficient isolation capability, so that in the above-described state of the high voltage circuit breaker, the electrical separation of the two Main power contacts may no longer be guaranteed.
  • At least one of the two insulating gas flows flowing into the region of the two main current contacts consists of insulating gas heated at least in such a way that the electrical separation of the two main current contacts is no longer ensured.
  • hot insulating gas has a lower insulating capacity than cold insulating gas.
  • the object of the invention is to provide a high-voltage circuit breaker in which in a state in which the two main current contacts and the two AbbrandURIe are no longer connected to each other, the electrical separation of the two main current contacts is ensured in each case.
  • a branching device is provided, which is provided with means for branching insulating gas from the derived from the region between the two AbbrandCounten Isoliergasströmung such that the two in the direction of The insulating gas flows flowing through the main current contacts have an approximately equal effect on the insulating gas present approximately in the region of the two main current contacts, so that the insulating gas is essentially not displaced in this region.
  • the insulating gas in the interior of the switch is substantially cold.
  • at least the insulating gas present between the burnup contacts in the interior of the insulating material nozzle is heated.
  • This Insulating gas expands and causes, inter alia, the two Isoliergasströmonne that are directed outside of the insulating material from both directions approximately along the longitudinal axis in the direction of the main power contacts. Since the effect of these two Isoliergasströmonne invention is about the same size, the insulating gas, which is located in the region of the separate main power contacts, not substantially displaced, but remains there largely maintained.
  • FIG. 1 shows a schematic longitudinal section through an embodiment of a high-voltage circuit breaker according to the invention and FIG. 2 shows a perspective view of a branching device of the high voltage circuit breaker of FIG. 1 ,
  • FIG. 1 a high-voltage circuit breaker 10 is shown, which has a longitudinal axis 11 and is formed substantially rotationally symmetrical.
  • a tulip-shaped Abbrandcard 15 is housed with an associated first HauptstomWallet 16 and a pin-shaped Abbrandcard 17 with an associated second main current contact 18.
  • the insulating gas may be sulfur hexafluoride (SF6) or nitrogen (N2) or tetrafluoromethane (CF4) or a mixture thereof.
  • the main current contacts 16, 18 are arranged radially outside of the consumable contacts 15, 17.
  • the contacts 15, 16 and the contacts 17, 18 are aligned coaxially with one another and in each case displaceable relative to one another in the direction of the longitudinal axis 11, namely from a short-circuited and thus activated end position into a separate and thus switched-off end position and back again.
  • the contacts 15, 16, 17, 18 are in contact with each other so that a current can flow through the contacts.
  • the contacts 15, 16 and the contacts 17, 18 are separated from each other, so that no current can flow.
  • a Isolierstoffdüse 20 is connected, which surrounds the two Abbrand tokene 15, 17, and which is further designed such that the pin-shaped Abbrand token 17 dip into the insulating 20 and seal it.
  • an arc 22 is produced which heats the insulating gas and thus leads to an expansion of the insulating gas in the interior of the tulip-shaped burnup contact 15.
  • this transition of the pin-shaped Abbrand token 17 out of the insulating 20 so that then the insulating gas can flow through the insulating 20 therethrough.
  • the contacts 15, 16, 17, 18 are shown in the off end position. This means that the contacts 15, 16 in the FIG. 1 to the left and the contacts 17, 18 in the FIG. 1 have been moved to the right relative to each other. In this separation movement of the contacts 15, 16, 17, 18 is formed - as already mentioned - the arc 22 between the AbbrandWalleten 15, 17. As soon as the pin-shaped AbbrandWallet 17 emerges from the insulating 20, this arc 22nd blown with insulating gas, which is supplied from a storage chamber 24 via a channel 25 that portion of the insulating material 20 in which the arc 22 is present.
  • the Isoliergasströmung 27 enters a first gas space 30, which is bounded by a tulip-shaped AbbrandWallet 15 supporting pipe 31.
  • the Isoliergasströmung 27 passes into a second gas space 34, which is bounded by the tube 31 and a tulip-shaped Abbrandcard 15, the first main current contact 16 and the insulating material 20 carrier 35 and thus radially outside the first gas space 30 is located.
  • the Isoliergasströmung 27 passes into a third gas space 37 which between the carrier 35 and the Porcelain housing 13 is formed and thus is located radially outside of the second gas space 34.
  • the insulating gas flows back toward the main power contacts 16, 18. This is in the FIG. 1 indicated by an arrow 39, which should represent the corresponding Isoliergasströmung.
  • the Isoliergasströmung 39 is thus aligned approximately parallel to the longitudinal axis 11 and in the direction of the two main power contacts 16, 18.
  • the Isoliergasströmung 28 enters a fourth gas chamber 41, which is formed by a pin-shaped AbbrandWallet 17 and the associated second main current contact 18 leading carrier 42. Through openings 43 in the carrier 42, the Isoliergasströmung 28 passes into a fifth gas space 45 which is formed between the carrier 42 and the porcelain housing 13 and thus is located radially outside of the fourth gas space 41. In this fifth gas space 45, the insulating gas flows back toward the main power contacts 16, 18. This is in the FIG. 1 indicated by an arrow 47, which should represent the corresponding Isoliergasströmung. The Isoliergasströmung 47 is thus aligned approximately parallel to the longitudinal axis 11 and in the direction of the two main power contacts 16, 18.
  • a branching device 50 is provided in the region of the openings 36, that is to say in the region of the transition from the second gas space 34 into the third gas space 37. With the aid of this branching device 50, insulating gas of the insulating gas flow 27 arriving via the second gas space 34 can be diverted into a sixth gas space 51.
  • the sixth gas space 51 is located in the axial direction following the second and third gas chambers 34, 37. The insulating gas flow 39 flowing out of the third gas chamber 37 is thus around that in the sixth in comparison to the insulating gas flow 27 arriving via the second gas chamber 34 Gas space 51 diverted insulating gas reduced.
  • the branching device 50 is shown in detail.
  • the branching device 50 is formed substantially rotationally symmetrical and arranged coaxially to the longitudinal axis 11 and is preferably made of aluminum.
  • the branching device 50 can also be made of a plastic, for example of PTFE.

  • the drive rod 54 is thus coupled via the tube 31 with the tulip-shaped AbbrandWallet 15 and the associated first main current contact 16.
  • the pin-shaped Abbrand token 17 and the associated second main current contact 18 are fixed in the present embodiment.
  • the transition from the switched end position to the switched-off end position and vice versa thus takes place in the described in the present embodiment, high-voltage circuit breaker 10 solely by a movement of the tulip-shaped AbbrandWallets 15 and the associated first main current contact sixteenth
  • the pin-shaped Abbrand token 17 and the associated second main current contact 18 are not fixed, but that the movement of the tulip-shaped AbbrandWallets 15 and the associated first main current contact 16 by means of a gear or linkage on the pin-shaped Abbrandcard 17 and the associated second main current contact 18 is transmitted, that they perform an opposite movement.
  • the branching device 50 has the FIG. 2 successively an axially aligned cylinder 57 and a radially oriented disk 58.

  • this outflowing insulating gas is indicated by means of an arrow 62.
  • the volume or the quantity of the insulating gas flowing out into the sixth gas space 51 depends on the flow resistance which the branching device 50 opposes to the outflowing insulating gas. This flow resistance in turn depends essentially on the cross-sectional area of the openings 60 of the branching device 50. The larger this cross-sectional area is, the more insulating gas flows into the sixth gas space 51, or the smaller this cross-sectional area, the less insulating gas flows into the sixth gas space 51.
  • the Isoliergasströmung 27 is passed through the first, second and third gas chamber 30, 34, 37 therethrough, and then as Isoliergasströmung 39 back toward the main power contacts 16, 18 to flow back.
  • a certain volume or a certain amount of Isoliergasströmung 27 is branched off in this way from the Isoliergasströmung 27 via the branching device 50 in the sixth gas space 51, so that the Isoliergasströmung 39 compared to the Isoliergasströmung 27 branched off to the sixth gas space 51 Insulating gas is reduced.

  • the insulating gas which is located radially outside of the insulating material 20 in a in the FIG. 1 is located as the seventh gas space 65 marked region, is acted upon from both directions with an approximately equal Isoliergasströmung 39, 47 and thus remains substantially stationary in the seventh gas space 65.
  • the insulating gas flows 27, 28 are formed by the heating of the insulating gas through the arc 22.
  • the insulating gas flows 27, 28 are therefore hot insulating gas.
  • the insulating gas, which is in the seventh gas space 65 is not heated by the arc 22 because it is separated from the arc 22 by the insulating nozzle 20.
  • the insulating gas in the seventh gas space 65 is therefore cold insulating gas.
  • the two Isoliergasströmonne 39, 47 are set approximately equal to achieve in this way that the insulating gas is not displaced in the seventh gas space 65. It is according to the representation in the FIG. 1 It is assumed that the diameter of the high-voltage circuit breaker 10 in the direction of the longitudinal axis 11 remains essentially the same.

  • the openings are variable.
  • the opening cross section of the openings changes between the switched-on end position and the switched-off end position. This can be achieved, for example, by providing the branching device 50 with a longitudinally displaceable or rotatable component which, together with the movement of the two consumable contacts 15, 17 relative to one another, performs a corresponding longitudinal or rotational movement and thereby more or less strongly defines the openings 60 closes or opens.
