Definitions

  • the invention is based on a high-voltage switchgear according to the preamble of claim 1.
  • the invention as set out in the independent claims is marked, solves the task, one with insulating gas creating pressurized high-voltage switchgear, in which the manual refilling of the insulating gas is omitted.
  • FIG. 1 shows a section of a High voltage switchgear with a greatly simplified pole shown of a hybrid circuit breaker 1 in switched off state.
  • This hybrid circuit breaker 1 is designed as an outdoor switch, has two in series switched extinguishing chambers 2 and 3, which here along a common longitudinal axis 4 extends mounted and concentric are arranged to this.
  • the first arcing chamber 2 is here designed as a gas-insulated switching chamber with a pressurized insulating gas or insulating gas mixture filled is
  • the second quenching chamber 3 is a vacuum interrupter executed and is enclosed by the insulating gas. It is however, the switching point of this second is quite possible Arcing chamber 3 also by means of other switching principles realize.
  • a transmission 5 is located between the two arcing chambers 2 and 3 arranged, which converts the movement of a drive 6 in the axial movement of the quenching chambers 2 and 3.
  • the drive 6 is arranged here at right angles to the longitudinal axis 4.
  • the Transmission 5 and the extinguishing chamber 3 are in a gas-filled, housing 7 connected to the interior of the arcing chamber 2 arranged.
  • the housing 7 can be made in one or more parts be the part of this housing 7 which contains the second arcing chamber 3 surrounds, but is always made of an insulating material.
  • the drive motor can be, for example, an electronically controllable one DC drive can be used.
  • This Design variant is to be regarded as particularly economical and it also enables the Contact speeds of the hybrid circuit breaker 1 to the adapt to any particular operational requirements. That arranged between the two quenching chambers 2 and 3 Gear 5 links the movements of the two quenching chambers 2 and 3 with each other and technically tunes their movements meaningful to each other.
  • the control commands for the drive 6 are transmitted via an optical fiber.
  • a mechanical one Pressure reducing valve 8 installed, which the inside of the Housing 7 with the inside of a flange Gas storage bottle 9 connects.
  • the gas storage bottle 9 is such a large supply of the insulating gas or Insulating gas mixture under comparatively high pressure saved that possibly at this Hybrid circuit breaker 1 occurring leakage losses over the Pressure reducing valve 8 can be automatically compensated.
  • the supply in the gas storage bottle 9 can be dimensioned in this way become that during a normal revision cycle of the Hybrid circuit breaker 1 no separate refilling of the same is necessary.
  • the pressure in the gas storage bottle 9 is so great is expected to liquefy the insulating gas needs to be, it makes sense to move it sideways or at an angle flanged to the housing 7 from below.
  • a metallic connector 10 attached, which on the Knife-shaped side facing away from the extinguishing chamber 2 is.
  • a metallic connector 11 attached, which knife-shaped on the side facing away from the arcing chamber 3 is trained.
  • Hybrid circuit breaker 1 electrically conductive with Terminals 12 and 13 of the switchgear connected.
  • the Connector 10 is with terminal 12 and that Connector 11 connected to terminal 13.
  • the Terminals 12 and 13 each have a U-shape trained, upwardly open resilient counter contacts on, in which the knife-shaped ends of the Connectors 10 and 11 are inserted from above, so that a very good current transfer is ensured.
  • the terminal 12 is with a busbar 14 High-voltage switchgear connected to the power supply to the hybrid circuit breaker 1.
  • Terminal 12 is supported by a post insulator 15, the earth side End is connected to a metallic support frame 16.
  • the Support frame 16 is located at ground potential Screwed foundation 17.
  • the terminal 13 is with a Busbar 18 of the high-voltage switchgear connected, which is used to supply power to the hybrid circuit breaker 1.
  • the connection terminal 13 is connected by a post insulator 19 worn, the earth-side end with a metallic Support frame 20 is connected.
  • the support frame 20 is also screwed to the foundation 17.
  • each pole of the hybrid circuit breaker 1 with one separate drive 6 and a separate automatic Gas refill unit is provided, each pole of the Hybrid circuit breaker 1 can be replaced separately. It is therefore very easily possible during the revision period of a pole to insert a replacement pole, whereby the Availability of the high-voltage switchgear advantageous is improved.
  • FIG. 2 shows a section of a metal encapsulated gas-insulated high-voltage switchgear.
  • This High-voltage switchgear has a housing 21, which encloses active parts, not shown, and which one extends along an axis 22.
  • the housing 21 is part of a section sealed against pressure metal-enclosed gas-insulated switchgear.
  • One face of the housing 21 has a flange 23 Opening, which is closed with a lid 24 pressure-tight is.
  • a pressure reducing valve 8 is pressure-tight in the cover 24 screwed, which flanged the inside of the Gas storage bottle 9 with the interior of the housing 21 connects.
  • the gas storage bottle 9 is in this Version outside the metal encapsulation.
  • This structure has the advantage that the gas storage bottle 9 if necessary during the operation of the high-voltage switchgear can be, but then the pressure reducing valve 8th be provided with a non-return flap so that the Remove the gas storage bottle 9 no insulating gas from the Can flow out of the housing 21.
  • everyone's pressure tight sealed sections of a metal encapsulated gas-insulated switchgear is with a separate automatic gas refill unit.
  • FIG. 3 shows a section of a metal encapsulated gas-insulated high-voltage switchgear.
  • This High-voltage switchgear has a housing 21, which encloses active parts, not shown, and which one extends along an axis 22.
  • the housing 21 is part of a section sealed against pressure metal-enclosed gas-insulated switchgear.
  • One face of the housing 21 has a flange 23 Opening, which is closed with a lid 24 pressure-tight is.
  • Inside the cover 24 is a pressure reducing valve 8 screwed pressure-tight, which the inside of a flanged gas storage bottle 9 with the inside of the Housing 21 connects.
  • the gas storage bottle 9 is included this version within the metal encapsulation.
  • This structure has the advantage that the gas storage bottle 9 through the Metal encapsulation is protected, especially then It is advantageous if the gas storage bottle 9 with insulating gas under particularly high pressure, for example 150 bar overpressure is filled.
  • the cover 24 has a molded pipe socket 25 provided, the opening in normal operation with, for example an overpressure valve 26 is closed in a pressure-tight manner.
  • the pressure relief valve can also be a rupture disc or a Pressure switch installed.
  • the working range of the pressure reducing valve 8 is at all Embodiments chosen so that the valve only at slow and comparatively minor pressure changes has a balancing effect and insulating gas in small quantities from the Gas storage bottle 9 makes up for sudden pressure drops that blocks inside the high-voltage switchgear Pressure reducing valve 8 the passage, because then a larger one Leak is present, the gas losses from the content of the Gas storage bottle 9 can no longer be compensated. In this way there will be greater gas losses and thus associated environmental degradation avoided. Instead of this Blockage can also be an orifice in the gas afterflow ensure that the gas loss in the event of a fault is tolerable Values is limited.
