Definitions

  • the invention relates to a high-voltage circuit breaker with a switching path, which is at least partially surrounded by an insulating nozzle having a gas opening into a storage volume gas channel, and with a at least partially disposed within the storage volume flow deflecting device.
  • Such a high-voltage circuit breaker is for example from the European patent application EP 0 783 173 A1 known.
  • a high-voltage circuit breaker is described, which has a switching path which is surrounded by a Isolierstoffdüse.
  • the insulating material nozzle has a switching gas channel, which opens into a storage volume.
  • a flow deflecting device is arranged within the storage volume.
  • the flow-deflecting device has a valve, which carries out a need-based opening or closing of a recess.
  • the arrangement of the flow-deflecting device is designed such that a buffering of switching gas is controlled in the storage volume via the position of the local valve.
  • the known valve has a movable valve body, which can be pressed in front of the recess spring-loaded. With frequent operation of the circuit breaker is also a frequent actuation of the valve. Movable parts within the storage volume are subject to wear. Due to the structural design of the storage volume immediate access, for example, to perform repairs is not readily possible.
  • EP 1 605 485 A1 known to equip a high-voltage circuit breaker with a Isolierstoffdüse whose switching gas channel opens into a storage volume.
  • the local storage volume is provided with a flow deflection device, which is intended to force a swirling of switching gas in so-called recirculation areas.
  • the invention has for its object to provide a circuit breaker of the type mentioned, which has a robust design and as possible wear a switching gas flow can steer.
  • the flow deflecting device has a Weggaseinbergskanalwandung limited switching gas inlet channel in which the switching gas channel switching gas radiating in the radiation and a wall of the insulating material in which the switching gas channel opens and the Weggaseinbergskanalwandung an annular gap limit, wherein the wall is spaced from the flow deflection device to form the annular gap.
  • a switching gas inlet channel in the flow-deflecting device causes a favorable flow during filling or emptying thereof within the storage volume. It can be dispensed with moving parts in the interior of the storage volume. About the arrangement of an annular gap between the wall, in which the switching gas channel opens, and the Heidelberggaseintrittskanalwandung is created a way to use a bypass to the switching gas inlet channel for switching gas control in the case of particularly large volumes of volatile switching gas occurring. Under regular conditions, a majority of the switching gas is passed through the switching gas inlet channel in a remote from the mouth region of the switching gas channel of the insulating material portion of the storage volume. This provides a possibility to provide sections within the storage volume which have different gas temperatures.
  • switching gas injected into the storage volume has a higher temperature than cold insulating gas not directly involved in the storage volume at a switching operation. Limited now one swirling of the cold insulating gas and the hot switching gas, if necessary, either preferably cool insulating gas or hot switching gas can be pressed out of the storage volume.
  • annular gap Due to the choice of an annular gap, it is possible on the one hand to influence the flow in the interior of the storage volume in order to provide sections in which cold insulating gas is swirled to a small extent with hot switching gas. On the other hand, a risk of the occurrence of undesirable overpressures in the area of the switching point can be reduced via the annular gap.
  • a further advantageous embodiment can provide that the switching gas inlet channel is an annular channel.
  • High-voltage circuit breakers of proven design typically have coaxially opposed arcing contact pieces and coaxially opposed rated current contacts on.
  • the arc and rated current contact pieces are also arranged coaxially to each other, so that space is provided between an arcing contact piece and a rated current contact piece in which, for example, a storage volume is located.
  • the storage volume preferably has a shape of a hollow cylinder, wherein filling and removal openings of the storage volume may preferably be arranged in frontal areas.
  • the switching gas channel of the insulating material can be designed, for example, in the region of its mouth as an annular channel with a substantially hollow cylindrical cross-section, wherein it is penetrated at least in a section of one of the arcing contact pieces.
  • an arc contact piece projecting into the switching gas channel is shielded by an electrically insulating auxiliary nozzle, so that the switching gas channel is designed as an annular channel whose surfaces on the shell side are formed from insulating material.
  • An outlet opening of the switching gas channel in the storage volume has an annular cross-section. Since flowing through the switching gas channel flooding switching gas almost completely and uniformly within the switching gas channel due to the pressure conditions arising, it is advantageous to design a low-resistance path for the switching gas, the switching gas inlet channel also designed as an annular channel.
  • the annular channel should have at its input, ie at the side at which the switching gas flows from the switching gas channel in the switching gas inlet channel, a corresponding cross-sectional area to the mouth opening of the switching gas channel.
  • the flowing from the switching gas channel in the storage volume switching gas can flow under low turbulence in the flow control device and continued there and forwarded.
  • the switching gas inlet channel has an input lying in the emission in front of an output, wherein the input has a smaller cross section than the output.
  • the flow resistance is reduced in the course of the switching gas inlet channel.
  • the pressure of the hot switching gas is reduced during the passage of the switching gas deflecting device.
  • a continuous flow through the switching gas inlet channel can be effected with switching gas, on the other hand, a calming of the forwarded from the switching point heated switching gas is made possible at a relatively early stage.

  • the hot switching gas or cold insulating gas can be introduced into the switching gas inlet channel via the return flow and there directed opposite to the emission direction of the switching gas channel and introduced into this.
  • the Heidelberggaseinbergskanalwandung has a circumferential to the switching gas inlet channel protruding shoulder.
  • a protruding shoulder makes it possible to provide an additional barrier within the storage volume, which inhibits unwanted crossing or strong mixing of switching gas or cold insulating gas. It is advantageous if the protruding shoulder rotates about the switching gas inlet channel.
  • a circulation can be provided in such a way that the shoulder extends in the radial direction and forms a barrier in the axial direction.
  • the projecting shoulder also extends in the axial direction and forms a barrier acting in the radial direction.
  • At least one return flow passage penetrates the protruding shoulder.
  • a switching contact piece projects into the switching gas channel.
  • the switching gas channel of the insulating material nozzle can preferably be penetrated by at least one switching contact piece. It can be provided that the switching gas channel at least temporarily is dammed by one of the switching contact pieces. However, it can also be provided that one of the switching contact pieces projects permanently into the switching gas channel. For example, it is possible for a contact piece projecting permanently into the switching gas channel to be surrounded by a so-called auxiliary nozzle in order to protect the contact piece protruding into the switching gas channel from hot switching gas.
  • the switching gas channel is rotationally symmetrical, which may have different cross sections in the course of a path.

  • an annular gap is formed between an outer lateral surface of the switching gas channel inlet wall and an inner lateral surface of the storage volume.
  • annular gap between an inner lateral surface of the storage volume and an outer lateral surface of the switching gas channel inlet wall makes it possible to provide an overflow path in addition to the annular gap between the wall in which the switching gas channel opens and the switching gas channel inlet wall.
  • this also flows over and flows through the annular gap in addition to the switching gas inlet channel.
  • the ratio of the flow resistance of the annular channels to the flow resistance of the flow inlet channel is in such a ratio that a preferred flow and guidance of the hot switching gases through the switching gas inlet channel through.
  • annular gaps may provide additional flow paths to guide, direct and direct switching gases.
  • the switching gas can flow into the portion of the storage volume in which cold insulating gas is kept. As a result, a swirling of hot switching gas and cold insulating gas is reduced. The cold switching gas can then flow via the switching channel in the switching path.
  • the switching gas inlet channel wall has a hollow truncated cone-shaped section and a return flow passage passes through the section.
  • a hollow frusto-conical portion of the switching gas inlet passageway wall may correspond to a flared one Be formed switching gas inlet channel.
