Definitions

  • the invention relates to a high-voltage circuit breaker with a first and a second, coaxial with each other opposing arcing contact piece, at least of which the first by a switch drive in the course of a Switching movement is drivable and in the off state are separated by a separation section and with a hollow cylindrical Insulating material nozzle with the first arcing contact is connected and the blowing of one if necessary burning between the arcing contact pieces Arc is used with an extinguishing gas, and to which one on the the side of the isolating section opposite the switch drive arranged component to be driven in the switching case coupled is.
  • FR 2 491 675 is a high-voltage circuit breaker known with two coaxial arcing contact pieces and with an insulating nozzle, which with a drivable arcing contact piece is connected.
  • the other arcing contact piece is by means of a reversing gear driven by a drive element, which in turn is connected to the switch drive and the isolating section bridged between the arcing contact pieces.
  • the Coupling of the second drivable arcing contact piece can also be connected to the switch drive by means of the insulating material nozzle respectively. For this purpose it is necessary to use the insulating nozzle to attach a transmission element itself.
  • the insulating nozzle is made of a plastic with limited strength and the corrosive influences the arc or hot extinguishing gases. Moreover the forces to be transmitted are very high when switching large, so that the coupling is mechanically stable have to be.
  • the present invention is therefore based on the object a high-voltage circuit breaker of the type mentioned Kind of creating a stable coupling of a driven one Component allowed to the insulating nozzle.
  • the insulating nozzle on its first, facing away from the drive side End has a bead arranged on a lateral surface, behind the one from the first end of the insulating nozzle Slid on first clamping ring with temporary radial elastic deformation of the first clamping ring and / or the Snap end of the nozzle and that a second clamping ring is provided, the first clamping ring and / or that Nozzle end to prevent unlocking the first Clamping ring supports and that the component to be driven at least one of the clamping rings can be coupled.
  • the coupling of a component to be driven to the insulating nozzle allows without drilling holes in the nozzle must be the stability of the nozzle body if necessary could affect. Since all components from have to be pushed on the first end of the insulating material nozzle, because the other end of the insulating nozzle has a larger one Has diameter, elastic deformability must be provided be the sliding of the first tension ring allowed behind the bulge of the insulating material nozzle. After this The second clamping ring is put on and if necessary with the first clamping ring Screws or connected by another type of fastening.
  • the first clamping ring is on the outside Slide on nozzle.
  • the first tension ring will either do this expanded and / or the first end of the nozzle is compressed radially. This is due to radial slots at the end of the nozzle allows.
  • the second clamping ring is put on, the in this case the radial compression of the nozzle end or must prevent the expansion of the first clamping ring.
  • the second clamping ring has a nozzle that either inserted into the inside of the nozzle end or in a circumferential groove on the face of the nozzle body is inserted. The second clamping ring prevents the first clamping ring pushed over the bead and thus unlocked can be.
  • the second clamping ring is either also into one on the front of the insulating nozzle circumferential groove inserted or on the outside of the nozzle body placed.
  • the second clamping ring allows in particular the coupling of a transmission element, in particular one Insulating rod that drives a drive movement across the Isolation path over to the second arcing contact piece can transmit.
  • a reversing gear provided in the form of a lever be actuated by the insulating rod so that the second arcing contact piece in the event of a shutdown of the the first arcing contact piece is moved away.
  • FIG. 1 shows a first arcing contact piece 1 in one Half cut and a second arcing contact piece 2, wherein the first arcing contact 1 as a tulip contact and the second arcing contact piece 2 is designed as a contact pin is.
  • the first arcing contact 1 is with a not shown Switch drive connected to the first arcing contact 1 when switching off in the direction of the arrow 13 moves.
  • the first arcing contact 1 is with a metallic Connected hollow cylinder 14 which carries an insulating nozzle 3. Another insulating nozzle body 15 is directly on the first arcing contact piece 1 placed. Moved when switching the insulating material nozzle 3 with the first arcing contact piece 1 together.
  • first and the second arcing contact pieces 1, 2 are separated from one another, an arc is drawn in the separating section 4 between them, which expands the quenching gas located there, for example SF 6 .
  • the hot quenching gas can flow out into a heating chamber 16, from which it flows back at a suitable time, for example directly after a current zero crossing of the current to be switched, in order to blow the arc.
  • the insulating material nozzle 3 bridges the separation path 4 both in the on state as well as in the off state.
  • On the Drive opposite side of the separation section 4 is the Body of the insulating material surrounded by a field electrode 5, which is pressed towards the separation section by means of a spring 19 is going to be there in the on state for a dielectrically favorable Design of the electrical field between the contacts to care.
  • the spring 19 is supported on the first clamping ring 8, which is attached to the first end 6 of the insulating nozzle 3 is.
  • the spring 19 could also be on an outer bead support the insulating material nozzle itself.
  • the field electrode 5 is through the continuous current contact piece 17 pushed back so far that this continuous current contact piece in contact with the other continuous current contact piece 18 can kick.
  • the field electrode 5 is by means of a Slide contact performed in the continuous current contact piece 17 and contacted.
  • a Drive rod 20 coupled, which is a deflection gear in the form a two-armed lever 21 operated on the other arm the second arcing contact piece 2 is coupled.
  • first clamping ring 8 which the bead 7 pushed over from the first end 6 of the insulating nozzle 3 can be and snaps behind the bead 7. This is either by an elastic design of the nozzle, for example through radial slots at the nozzle end or through a slit of the first clamping ring 8 is reached.
  • the both stabilizes the nozzle body 3 and the first clamping ring 8 in such a way that there is no elastic deformation and therefore no sliding over the first clamping ring 8 over the bead 7 more is possible.
  • the second clamping ring 10 has a nozzle 11, which in the groove 12 engages on the end face of the nozzle body 3 and a radial deformation of the nozzle body both towards the inside and also prevented to the outside.
