Definitions

  • the invention relates to a high-voltage circuit breaker with two arcing contact pieces facing each other coaxially and with an insulating nozzle that at least a switching distance during the switch-off process between the arcing contact pieces and the one Passage channel that is in the on state of one first of the arcing contact pieces is blocked, which a shaft and an end piece with reduced compared to the shaft Has diameter.
  • Such a high-voltage circuit breaker is known, for example, from US 4,342,890.
  • the arcing contact pieces are separated from one another in the axial direction during the switching-off process, whereupon an arcing arises between them in the switching path in many switching cases.
  • This arc heats up the existing extinguishing gas, usually SF 6 , and flows into a boiler room, where it is temporarily stored. From there, the extinguishing gas, which is under high pressure, then reaches the switching path when the current passes through zero and the arc is extinguished accordingly in order to cool it and to prevent the arc from reigniting.
  • the insulating material nozzle is intended to align the flow of extinguishing gas, to accelerate the flow of extinguishing gas and to control it.
  • the through-channel of the insulating material nozzle is closed by an arcing contact piece until the extinguishing position is reached, so that a high quenching gas pressure can initially build up in the switching path, which results in an intensive flow after opening the through-channel.
  • the present invention is therefore based on the object a high-voltage circuit breaker of the aforementioned Type to create, on the one hand, when releasing the insulating material nozzle through the arcing contact piece, if possible large amount of extinguishing gas in the area of the switching path Is available, and on the other hand, the dielectric Strength in the area between the end piece of the arcing contact piece and the material of the insulating material nozzle is.
  • the Through channel has a cylindrical region, the Diameter is only slightly larger than the diameter of the shaft.
  • the configuration according to the invention ensures that on the one hand the through channel until it is released the shaft of the first arcing contact piece largely closed is and that from the time of opening of the through channel to the end piece of the arcing contact piece already through a sufficient gap from the material of the Isolating nozzle is separated so that the dielectric Stress in the intermediate area between the first Arc contact piece and the material of the insulating material nozzle is reduced.
  • This also provides a good seal for the through-channel reached by the first arcing contact piece as long as the shaft the cylindrical region of the through-channel blocked.
  • Between the outer diameter of the shaft and the Wall of the through-channel must for tolerance reasons and around easy mobility of the arcing contact ensure that a certain gap width is provided, however, this gap is so narrow that there is little quenching gas is lost, in particular that at least to Start of switching off the through channel on a large length is blocked, so that the extinguishing gas over a large length must flow through the gap in order to Expansion room to arrive. This is by means of a known one Nozzle with a local constriction practically inaccessible.
  • An advantageous embodiment of the invention provides that the length of the end piece is greater than the length of the cylindrical area.
  • a further advantageous embodiment of the invention provides that the length of the cylindrical portion is greater than its diameter, in particular larger than twice the Diameter. It can also be advantageously provided that the length is greater than three or four times the diameter of the cylindrical area.
  • the passage channel only opens after one large stroke of the contact pin, so that before training the extinguishing gas flow over a long time a high Can form quenching gas pressure in the heating or compression room.
  • a further advantageous embodiment of the invention provides before that between the end piece and the shaft of the first Arc contact piece provided a conical transition area is.
  • the through-channel on the part facing away from the second arcing contact A conical extension at the end of the cylindrical area having.
  • the figure schematically shows part of the interrupter unit of a high-voltage circuit breaker according to the invention.
  • an insulating circuit breaker housing 18 for example consists of porcelain or a composite material, are two arcing contact pieces 1,2 coaxially opposite.
  • the first arcing contact 1 is stationary or separately drivable, while the second arcing contact piece 2, which has the shape of a tulip contact has, in the direction of arrow 14 for execution an opening movement and in the opposite direction to the execution a switch-on movement can be driven.
  • the second arcing contact piece 2 is an insulating body 3 firmly connected in the form of an insulating material nozzle, which consists of polytetrafluoroethylene.
  • the insulating material nozzle 3 has a through channel 6, which in the on state penetrated and blocked by the first arcing contact 1 is.
  • Radially outside the insulating nozzle 3 and this surrounding are a first continuous current contact piece 13 and a second continuous current contact piece 12 arranged in the on state are also in contact with each other and the Carry rated current.
  • a boiler room 16 is formed, which is via a channel 15 with the through channel 6 of the nozzle or between the Arcing contact pieces 1,2 connected arc space connected is.
  • an arc 4 can arise between the arcing contact pieces 1 , 2, which heats up the quenching gas located in the arcing chamber 5, for example SF 6 , and thus expands it.
  • the quenching gas can then flow into the heating chamber 16 and is temporarily stored there until the arc 4 extinguishes due to a zero crossing of the current to be switched and the quenching gas flows back from the heating chamber 16 through the duct 15 into the arc chamber 5 in order to bring about rapid cooling there and thus to prevent the backfire of an arc 4.
  • the through channel 6 is in an essential area 17 of its length cylindrical, so that on the one hand the Damage by the first arcing contact 1 at Switching off continues until there is sufficient extinguishing gas pressure is reached in the arc room 5 or in the heating room 16 and that, on the other hand, there is a large axial overlap of the Shaft 8 with the through channel 6 to an effective seal leads.
  • the second phase of the switch-off movement begins with the separation of the first arcing contact 1 from the second Arcing contact piece 2. Now arises between the arcing contact pieces 1 and 2 an arc that detects the gas in the Arc room 5 heats up and allows expansion. To this At a point in time or somewhat later, the shaft 8 leaves the cylindrical one Area 17 of the through channel 6. This will now only blocked by the end piece 7, so that part of the expanded extinguishing gas the gap between the end piece 7 and the cylindrical region 17 of the through-channel 6 can flow through and so the dielectric problems in the Gap reduced.
  • the extinguishing gas flowing through causes, among other things, the dielectric Solidification of the space between the end piece 7 and the insulating body 3.
