Definitions

  • the invention is based on a circuit breaker according to the preamble of claim 1.
  • a circuit breaker which has an arcing chamber with two fixed, spaced-apart erosion contacts.
  • the quenching chamber is filled with an insulating gas, preferably SF 6 gas under pressure.
  • an insulating gas preferably SF 6 gas under pressure.
  • the bridging contact concentrically surrounds the cylindrical erosion contacts.
  • the bridging contact and the two erosion contacts form a power current path which is only subjected to current when it is switched off.
  • the bypass contact slides down from a first of the erosion contacts and draws an arc, which initially burns between the first erosion contact and the end of the bypass contact facing it.
  • the pressurized insulating gas required for the blowing is generally generated by means of a blowing piston connected to the movable bypass contact.
  • This circuit breaker also has a nominal current path parallel to the power current path, which carries the operating current when the circuit breaker is switched on.
  • the nominal current path is arranged concentrically around the power current path.
  • the bridging contact is mechanically rigidly connected to a movable nominal current contact arranged in the nominal current path.
  • the bridging contact Due to its dimensions, the bridging contact has a comparatively large mass to be moved, which has to be accelerated and braked during switching operations.
  • the circuit breaker drive must provide the energy required for this.
  • Another circuit breaker is known from the published patent application DE 31 27 962 A1, which has an arcing chamber with two fixed, spaced-apart erosion contacts.
  • the quenching chamber is filled with an insulating gas, preferably SF 6 gas under pressure.
  • an insulating gas preferably SF 6 gas under pressure.
  • the bridging contact concentrically surrounds the cylindrical erosion contacts.
  • Of the Bridging contact is also designed here as a nominal current contact. Opening this circuit breaker is similar to the circuit breaker described above.
  • this bridging contact Due to its dimensions, this bridging contact also has a comparatively large mass to be moved, which must be accelerated and braked during switching operations.
  • the circuit breaker drive must provide the energy required for this.
  • the invention solves the problem of creating a circuit breaker of the type mentioned, in which an increase in the speed of the bridging contact is achieved with a comparatively small and low-energy drive.
  • the circuit breaker's rated current path should have a particularly high fatigue strength.
  • the bridging contact is arranged inside the erosion contact arrangements and extends along the central axis, it can be designed with an advantageously small diameter and thus with a particularly small mass.
  • This circuit breaker can therefore be operated at a comparatively high opening speed, since this low-mass bridging contact can be accelerated effectively with a comparatively small and advantageously inexpensive drive and can be braked again reliably at the end of the opening movement.
  • the bridging contact is also designed here as a simple switching pin, which has no resilient contact elements, it is therefore comparatively simple and inexpensive to manufacture.
  • the movable nominal current contact is moved much more slowly than the bridging contact connected to it via a speed-reducing lever linkage.
  • the service life of the rated current contacts is advantageously increased due to the lower mechanical stress, which significantly improves the availability of the circuit breaker.
  • the movable nominal current contact is accommodated in a volume which is completely separated from the area of the circuit breaker in which hot gases and combustion particles generated by the arc occur. These hot gases and combustion particles can therefore not negatively influence the nominal current contacts, which advantageously increases their stability and thus their service life.
  • a further advantageous reduction in the cost of the circuit breaker designs according to the invention results from the fact that the erosion contact arrangements and in some cases also the housing parts are constructed from identical parts in mirror image to a plane of symmetry.
  • FIG. 1 shows a schematically represented section through the contact zone 1 of the arcing chamber of a first embodiment of a circuit breaker according to the invention in the switched-on state.

  • the contact basket 7 has contact fingers made of metal, which resiliently rest on the surface of the switching pin 3.
  • an erosion plate 9 has been connected to this carrier 8 using one of the known methods, in such a way that the ends 10 the contact fingers are protected against erosion.
  • the erosion plate 9 is preferably made of graphite, but it can also consist of other electrically conductive, erosion-resistant materials such as, for example, tungsten copper connections.
  • the surface of the erosion plate 9 facing away from the carrier 8 is protected against arcing by means of an annular cover 36 made of an erosion-resistant insulating material. In addition, the cover 36 prevents the arc base from moving too far into the storage volume 17.
  • the structure of the erosion contact arrangement 6 corresponds to that of the erosion contact arrangement 5, but it is arranged as a mirror image of the latter.
  • a dash-dotted one Line 11 indicates the plane of reflection which is perpendicularly penetrated by the central axis 2.
  • the erosion contact arrangement 6 has a schematically illustrated contact basket 12, which is connected in an electrically conductive manner to a shoulder of a plate-shaped carrier 13 made of metal.
  • the contact basket 12 has contact fingers made of metal, which resiliently rest on the surface of the switching pin 3.
  • an erosion plate 14 On the side of the carrier 13 facing the erosion contact arrangement 5, at the point of the smallest distance between the two erosion contact arrangements 5 and 6, an erosion plate 14 has been connected to this carrier 13 using one of the known methods, in such a way that the ends 15 the contact fingers are protected against erosion.
  • the erosion plate 14 is preferably made of graphite, but it can also consist of other electrically conductive, erosion-resistant materials such as, for example, tungsten copper connections.
  • the surface of the erosion plate 14 facing away from the carrier 13 is protected against arcing by means of an annular cover 41 made of an erosion-resistant insulating material.
  • the cover 41 prevents the arc base from migrating too far into the storage volume 17.
  • the carriers 8 and 13 and the partition 16 enclose an annular storage volume 17, which is designed for storing the pressurized insulating gas provided for blowing the arc.
  • the carrier 8 represents an end face of a cylinder-shaped exhaust volume 18 completely enclosed by metallic walls.
  • the carrier 13 represents an end face of a cylinder-shaped exhaust pipe completely metallic walls of enclosed exhaust volume 19. If a nominal current path is provided, the movable nominal current contacts present in this nominal current path represent the electrically conductive connection between the metallic walls of the two exhaust volumes 18 and 19 when the circuit breaker is switched on.
  • the switching pin 3 becomes in this case only comparatively small stray currents flow through it.
  • the carrier 13 is provided with a bore 20, which is closed with a check valve 21 shown schematically.
  • a line 22 is connected to the bore 20, which leads the insulating gas compressed by a piston-cylinder arrangement that is operatively connected to the switching pin 3 to the storage volume 17 during a switch-off process.
  • an inflow of the pressurized insulating gas into the storage volume 17 is only possible if there is a lower pressure in the storage volume 17 than in the line 22.
  • FIG. 2 shows a schematically illustrated section through the contact zone 1 of a first embodiment of the arcing chamber of a circuit breaker according to the invention during the opening.
  • the switching pin 3 has drawn an arc 23 between the erosion plates 9 and 14 in the course of its opening movement in the direction of arrow 27.
  • the arc 23 thermally acts on the insulating gas surrounding it and thereby briefly increases the pressure in this area of the arcing chamber, designated as the arc zone 24.
  • the pressurized insulating gas is briefly stored in the storage volume 17. However, part of the pressurized insulating gas flows through an opening 25 into the exhaust volume 18 and through an opening 26 into the exhaust volume 19.
  • the switching pin 3 is connected to a piston-cylinder arrangement, in which insulating gas is compressed during a switch-off process. As indicated by an arrow 28, this compressed insulating gas is introduced into the storage volume 17 through the line 22 when the pressure in the storage volume 17 is lower than in the line 22. This is the case, for example, when the arc 23 is so low in current, that it cannot heat the arc zone 24 intensely enough. However, if a high-current arc 23 heats the arc zone 24 very strongly, so that a high pressure of the insulating gas occurs in the storage volume 17, an excess pressure valve 29 opens after a predetermined limit value is exceeded and the excess pressure is released into the exhaust volume 18. However, it is also possible if the circuit breaker is designed, for example, only for comparatively small breaking currents, to dispense with the pressure relief valve.

  • the current through the circuit breaker then flows, for example, from the current connections 49 through the housing wall 42, through the contact fingers 56 and the housing wall 46 to the current connections 50.
  • the space 57 in which this movable part of the rated current path is accommodated, is very advantageously completely separated from the arc zone 24 by the insulating partition 16 and the supports 8 and 13, so that no burn-up particles generated in the arc zone 24 reach the area of the rated current contacts and can negatively influence them.
  • the service life of the rated current contacts is thereby increased very advantageously, which results in an advantageously increased availability of the circuit breaker.
  • the lever linkages which each consist of a lever 52, a rocker 53 and a rod 54 are designed so that the comparatively high switch-off speed of the switching pin 3 generated by the drive, not shown, which is in the range from 10 m / sec to 20 m / sec is, is implemented in an approximately ten times lower turn-off speed of the finger basket 55 from about 1 m / sec to 2 m / sec.
  • the mechanical stress on the finger basket 55 and also on the contact fingers 56 is advantageously small, so that these components can be designed to be comparatively light and low in mass since they do not have a large mechanical load Have to withstand stress.

  • the guide part 58 is connected to the carrier 13 by means of ribs arranged in a star shape.
  • the contact elements are each designed as identical parts.
  • the use of the same parts advantageously reduces the manufacturing costs of the circuit breaker and also simplifies the storage of its spare parts.
  • the switching pin 3 draws an arc 23 in the course of its switching-off movement between the erosion plates 9 and 14.
  • the switching pin 3 moves at a comparatively very high switch-off speed, so that the arc 23 burns only briefly on the tip 4 of the switching pin 3 and immediately on the Burning plate 14 commutates.
  • the tip 4 therefore shows hardly any signs of erosion.
  • the erosion plates 9 and 14 are made of a particularly erosion-resistant material, and therefore they have a comparatively long service life.
  • the circuit breaker therefore only needs to be used comparatively rarely be revised, which means that it has a comparatively high availability.
  • the arc 23 will reach its full length comparatively quickly because of the very rapid switch-off movement of the switching pin 3, so that shortly after the contact separation, the full arc energy is available for pressurizing the insulating gas in the arc zone 24.
  • the arc 23 thermally acts on the insulating gas surrounding it and thereby briefly increases the pressure in the arc zone 24 of the arcing chamber.
  • the pressurized insulating gas is briefly stored in the storage volume 17. However, part of the pressurized insulating gas flows through an opening 25 into the exhaust volume 18 and through an opening 26 into the exhaust volume 19.
  • the switching pin 3 is generally connected to a piston-cylinder arrangement in which insulating gas is compressed during a switch-off process. This compressed insulating gas is introduced into the storage volume 17 through the line 22 in addition to the thermally generated pressurized insulating gas.
  • this inflow only takes place if there is a lower pressure in the storage volume 17 than in the line 22. This is the case, for example, before the contact separation or when the arc 23 is so weak that it cannot heat the arc zone 24 intensely enough. However, if a high-current arc 23 heats the arc zone 24 very strongly, so that a comparatively high pressure of the insulating gas occurs in the storage volume 17, at this high pressure there is initially no inflow of the compressed gas generated in the piston-cylinder arrangement. If a predefined limit value of the stored pressure is exceeded in the storage volume 17, this opens after this predefined limit value has been exceeded Pressure relief valve 29 and the excess pressure is reduced into the exhaust volume 18. In this way, it is prevented with great certainty that an inadmissible exceeding of the mechanical strength of the components can occur in this area.
  • the two gas flows are similar because of the very similarly designed flow areas, so that the pressure built up in the arc zone 24 flows approximately evenly and in a controlled manner to both sides, as a result of which the insulating gas present in the storage volume 17 for quenching the arc 23 is stored under pressure for so long until the arc 23 can be blown.
  • the circuit breaker according to the invention is particularly well suited for switchgear in the medium-voltage range.
  • the compact cylindrical design of the circuit breaker is particularly suitable for installation in metal-enclosed systems, in particular also for installation in metal-enclosed generator leads.
  • the circuit breaker is very well suited for the replacement of obsolete circuit breakers, since it, with the same or better breaking capacity, requires much less space than this, generally no complex structural changes are necessary with such a retrofitting. If the circuit breaker is to be used for operating voltages above approximately 24 kV to 30 kV, the distances a and b must be increased and adapted to the required voltage; if necessary, the opening speed of the switching pin 3 must also be adjusted accordingly, ie increased.
  • the switch-on speed of the switching pin 3 in this circuit breaker is in the range 5 m / sec to 10 m / sec, while the contact fingers 56 of the nominal current contact move into their switch-on position with a corresponding switch-on speed in the range of 0.5 m / sec to 1 m / sec.
