Definitions

  • the invention relates to a gas pressure switch of the type mentioned in the preamble of claim 1.
  • Such switches are known for example from US Pat. Nos. 4,149,051 and 4,144,426.
  • the end of the two arcing contacts on the outflow side is surrounded by a cooler composed of winding layers of metal mesh arranged one above the other, which cooler is intended to cool the emerging hot switching gases and also to at least partially reverse their flow axially.
  • these coolers represent an obstacle to the gas flow suddenly occurring during a switch-off stroke.
  • This obstacle can have the result that the gas flow leaving the blow nozzle after the blowing of the switching arc and before this gas flow reaches the downstream end of the arcing contact, to a certain extent a "standing" Wave "superimposed, ie strong vibrations form in the gas stream leaving the blow nozzle, which alternately and at a very high frequency result in areas with higher and lower pressure in this gas stream.
  • Reduced pressure also means reduced gas density and thus reduced dielectric strength of the gas, especially since it is still partially ionized can be.
  • These cooling plates also represent an obstacle to the gas flow suddenly occurring during a switch-off stroke, which is not only a result of the extinguishing gas flowing out of the pressure chamber, but also a result of the sudden heating of the extinguishing gas in the area of the switching arc.
  • the invention is based on the object of designing a switch of the type mentioned in such a way that, during a switch-off stroke, the "grafting" of the cold extinguishing gas can be suppressed against a minimum of resistance and that the hot switching gases are not primarily cooled by convection Cooling surfaces takes place, but takes place by swirling the hot switching gases with the still cool quenching gas of the "graft", which was not directly in contact with the switching arc.
  • FIGS. 1 and 2 The switch shown is a metal-encapsulated gas pressure switch 10 with an essentially tubular, metallic housing 11 which contains an extinguishing gas, for example SF 6 , under excess pressure. At the top, the housing 11 is tightly closed by means of a support insulator 12, which in turn is clamped by means of an annular flange 13. A connection conductor 14, which is tightly enclosed and only schematically indicated, leads centrally through the support insulator 12. A deflection hood, designated as a whole by 16, is fastened to the lower end of the connection conductor 14, which projects into the interior 15 of the housing 11.
  • an extinguishing gas for example SF 6
  • This has a base part 17, on the outer side facing the support insulator 12, a connecting piece 18 for receiving the lower part of the connecting conductor 14 is formed.
  • the side of the base part 17 opposite the connector 18 has a deflection surface 19 in the form of a hollow, half torus, a conically tapered flow body 20 being inserted in the base part 17 in the axis of this toroidal deflection surface 19.
  • a fastening and spacing ring 21 is fastened to the outside thereof, for example by means of pins or screw bolts (not shown).
  • a likewise metallic, cylindrical section 22 Connected to the metallic base part 17 is a likewise metallic, cylindrical section 22, the inner surface 23 of which is flush with the peripheral part of the deflecting surface 19.
  • the section 22 is pressed firmly against the base part by means of a retaining ring 24.
  • Support ribs 25, for example four of them, project radially inwards from the inside of the metallic retaining ring 24, which essentially corresponds to the section 22 with respect to the inside and outside diameter.
  • threaded bores 26 (only one is shown) into which clamping bolts 27 are screwed, the head of which is supported by the base part 17 (FIG. 1, top right).
  • the support ribs 25 carry at their inner end a part of a fixed nominal current contact 28 supporting ring 29, on the lower end of which a ring is radially outwardly deflectable deflectable contact fingers 30 which engage in the switched-on position (Fig. 1, left) with a movable Are rated current contact 31, the construction and other function will be described with reference to FIG. 2.
  • radially inwardly projecting support ribs 32 are also fastened, which are preferably aligned with the support ribs 25 and carry at their inner end a tubular hub part 34 forming part of a fixed arcing contact 33.
  • this hub part 34 is attached in a replaceable manner (for example by screwing) a tubular (that is blow-through) tear-off contact pin 35 which forms the other component of the fixed arcing contact 33.
  • This has a central bore 36 extending from its free end, which widens and from which lateral passages 37 extend before the end of the pin 35, the bore 36 continuing in the bore in the hub part 34.
  • the tear-off contact pin 35 closes in the switched-on position a blowing nozzle 38 belonging to the movable components of the switch and made of an electrically insulating material, for example made of PTFE, and engages in an essentially tubular end piece 39, which in itself is the movable one Arcing contact forms in the sense that a foot point of the switching arc attaches to this end piece 39.
  • two sets of six tongues 41, 42 each are fastened at uniform circumferential intervals, the sets of tongues 41, 42 being arranged in two different planes.
  • the tongues 41 and 42 are preferably made of conductive material are planar and preferably with their planes transverse to the axis of the portion 22.
  • the tongues 41 are in relation to the tongues 42 each arranged rotated by 30 0, which on account of the ease of illustration does not appear from Fig. 1.
  • the function of the tongues 41 and 42 will be described below.
  • windows 43, 44 are also formed in section 22, which lead radially outward from the interior 45 of the deflection hood 16. These windows 43, 44 are covered by a thin-walled pipe 46, which surrounds the section 22 at a radial distance and is fastened to the fastening ring 21, preferably made of metal. Between this tube 46 and the outer surface of section 22 there is thus a shell space 47 which, as can be seen in FIG. 1, is open at the bottom.
  • the upper part essentially shows the components already described in the lower part of FIG. 1, so that a repeated description, apart from the assignment of the same reference numbers, appears to be superfluous.
  • the movable nominal current contact 31 has a shoulder 48, by means of which an inlet-side peripheral flange 49 of the blow nozzle 38 is clamped on the end face of an outer, metallic cylinder 50.
  • the movable nominal current contact 31 is screwed axially by means of bolts 51 onto a circumferential bead 52 projecting outwards from the cylinder 50.
  • the cylinder 50 is connected via an essentially ring-shaped base 53 made of conductor material to an inner, also metallic cylinder 54, which is at the same time a component of the movable arcing contact and serves in this regard as a blow-out pipe and for current supply.
  • an inner, also metallic cylinder 54 On the upper end face of the inner cylinder 54 the end piece 39 already mentioned is exchangeably fastened, e.g. screwed in.
  • the jacket space between the cylinders 50 and 54 is a pumping or pressure chamber 55, which leads directly into the blowing nozzle 38 at one end and which is delimited at the other end by a stationary, ring-shaped pumping piston 56.
  • the pump piston 56 is both sealed against the outer wall of the cylinder 54 as well as against the inner wall of the cylinder 50 and these two cylinders are displaceable along the pump piston 56.
  • the pump piston 56 is supported on a plurality of columns 57 (three here). Each column 57 is slidably guided through a passage 58 formed in the bottom 53.
  • each column 57 has a metallic spacer sleeve 59, which is supported on one end on the side of the pump piston 56 facing away from the pressure chamber 55 and on the other end on the base piece 60 of a further deflection hood 61.
  • Each spacer sleeve 59 is clamped by means of a clamping bolt 62 which passes through it and is screwed into the base piece 60.
  • each spacer sleeve 59 is engaged by a sliding contact 63 embedded in each of the bushings 58, which ensures a good electrical connection between the cylinders 50 and 54, which are already galvanically connected to one another, and - via the spacer sleeve 59 - the base piece 60.
  • a plurality of support ribs 64 protrude radially inward from the inner wall of the cylinder 54 and carry an aerodynamically shaped end part 65 of a drive rod 66.
  • a connecting and push rod 67 preferably made of an electrically insulating material, adjoins the end part 65 and is guided displaceably through a central bore 68 in the base part 60 and - as indicated by dashed lines - is coupled to a drive 69.
  • the moving denomination Power contact the movable arcing contact 40 and the blowing nozzle 38 are firmly coupled to the drive rod 66. It also results that the movable arcing contact 40, which essentially consists of the end piece 39 and the inner cylinder 54 (as soon as the end piece 39 is released from the fixed arcing contact 33 in the course of a switch-off stroke), can be blown through, the flow channel 70 being supported by the supporting ribs 64 , which offer no significant flow resistance, is enforced.
  • the downstream end of the movable arcing contact 40 is spanned by the aforementioned deflection hood 61, the bottom part 60 of which, as mentioned, is arranged in a stationary manner and therefore also serves as a connection point for the second connecting conductor 71.
  • This bottom piece 60 also has on its side facing the arcing contact 40 a deflection surface 72 surrounding the bore 68 in the form of a half, hollow torus.
  • the deflection hood 61 also has an essentially cylindrical section 73, which connects tangentially to the peripheral part of the deflection surface 72 of the base part 60 and is fastened thereon.
  • a set of tongues 75, 76 are fastened to the inside 74 of section 73 in two planes perpendicular to the axis of section 73.
  • These tongues 75, 76 are also conductive, planar and at right angles to the axis of section 73 and are each arranged at uniform circumferential intervals.
  • the extinguishing gas present in the pump chamber 55 is first pre-compressed.
  • the end piece 39 leaves the tear-off contact pin 35, but even before it has released the blowing nozzle 38, the blowing of the switching arc drawn between 39 and 35 begins, the heated switching gases initially flowing out through the flow channel 70, on the deflection surface 73 outward and axially deflected are and then get into the cylindrical section 73 with the tongues 75, 76, where, by the presence of the tongues, they are vigorously swirled with the still cool extinguishing gas already present in the cylindrical section 73, without it producing any of the flow superimposed "standing wave" could come.
  • the deflection hood 61 associated with the set of movable contacts 31, 40 can also be designed similarly to the deflection hood 16, namely with windows and with a thin-walled tube covering them at a radial distance.
