Definitions

  • the present invention relates to the field of medium and high voltage engineering, in particular to circuit breakers with high current carrying capacity in the medium and high voltage range.
  • a circuit breaker of the type mentioned above is about DE 3341903 A1 known.
  • the known power switch has mutually movable switching pieces whose Abbrand- and rated current contacts are moved along the common longitudinal axis of the switch. During the switch-on movement, the movable burn-off contact is moved into the fixed burn-off contact. All finger-shaped rated current contacts of the movable contact piece are coaxial and arranged at the same distance to the Abbrandmind. A portion of the rated current contact fingers are upstream of the remaining rated current contact fingers in the direction of the longitudinal axis.
  • the finger-shaped rated current contacts travel over the counter-nominal current contact designed as a cylindrical contact piece, and the current first commutates through the already closed burn-off contacts to the upstream rated current contact fingers and then on the remaining, shorter trained Nennstromtitlefinger.
  • the upstream rated current contact fingers are designed to be arc-proof.
  • the inventive circuit breaker is advantageously filled with a Extinguishing gas and includes two relative to each other and along a longitudinal axis of the switch movable contact arrangements.
  • the contact assemblies include a consumable contact system and a rated current contact system, wherein the rated current contact system is electrically connected in parallel with the consumable contact system. If necessary, an arc burns between AbbrandWalleten the AbbrandWalletsystems.
  • One of the two contact arrangements has inner rated current contacts and outer rated current contacts, wherein the inner rated current contacts are upstream of the outer rated current contacts in the direction of the longitudinal axis, ie the inner contacts extend beyond the outer contacts along the longitudinal direction of the switch.
  • the outer rated current contacts are arranged in a ring and surround the inner rated current contacts coaxially.
  • the inner rated current contacts are in turn arranged in a ring around the Abbrandcardsystem.
  • a rated current contact system of the circuit breaker is here to distinguish a Abbrandcardsystem or to an auxiliary contact system which, for example, a turn-on understood that contact system that has the comparatively lowest electrical resistance, and is designed to permanently run the current flowing in the switch rated current.
  • the coaxial arrangement of the outer rated current contacts around the annular inner inner rated current contacts forms an annular gap between the inner rated current contacts and the outer rated current contacts into which the counter current contact is driven when closing the switch.
  • the annular gap formed the Jacobnennstrom meme is clamped so between inner and outer rated current contacts and thus contacts both internal and external rated current contacts.
  • the division of the current flow to inner and outer rated current contacts is advantageous because thus does not flow the entire current through the outer rated current contacts and the electromagnetic force caused by the current flow through the outer contacts is reduced.
  • the reduced electromagnetic force due to the reduced current flow through the outer contacts reduces the contact pressure on the contacting Gegenstromnstromtitle and thus reduces the force acting between the rated contacts and the Gegennennstrom prominence frictional force in a movement of the contact assemblies during an occurring short circuit case in the switch.
  • the AbbrandCountsystem two movable, hollow cylindrical Abbrand tokene which contact in the closed state of the switch at their end faces.
  • the end face or end face is to be understood that surface which limits the lateral surface of the hollow cylindrical burnup contacts.
  • the frontally contacting the Abbrandcarde proves advantageous over such contact systems, in which there is an overlap of the contacts, since no frictional force caused by the overlap by the drive of the switch must be overcome.
  • the inventive method for switching on an electrical line switch for the range of high or medium voltage with two contact arrangements, which form a Abbrandnesssystem with AbbrandCounten and a parallel electrically switched nominal current contact system comprises the method steps: moving both contact assemblies relative to each other, towards each other and along a longitudinal axis of the switch.
  • the two consumable contacts of the consumable contact system contact one another at their end faces. That is, the faces abut each other, both burn-off contacts are designed as a hollow cylinder.
  • the burn-off contacts are in electrical contact, contact in another phase, the rated current contacts of the rated current contact system with each other.
  • This further phase is characterized in that the inner rated current contacts which project beyond the outer rated current contacts in the direction of the longitudinal axis, first contact the Gegennennstromtitle and then contact only the outer rated current contacts this Gegennennstromtitle.
  • the inner rated current contacts are coaxially surrounded by the outer rated current contacts. This sequential contacting of the inner and outer rated current contacts ensures that the later contacted outer rated current contacts will not experience wear by current flow upon contact. Due to the fact that first the inner rated current contacts are contacted in the switch-on, acts at the moment of contact and current flow, an electromagnetic force which is directed so that it counteracts the contact force between Jacobennstrom toast and inner rated current contact. This reduces the frictional force to be overcome by the drive of the switch, which occurs during the switch movement. The contact is thus improved during the turn-on and turn-off and in particular during a short circuit case.
  • circuit breakers used as generator switches are used, for example, to completely decouple a wind farm with a large number of wind turbines from the electrical power grid or to connect such a wind farm to the electrical power grid.
  • Fig. 1 shows a section of an inventive circuit breaker 1 which is designed as a generator switch and for a typical rated voltage of 24 KV, a nominal current of 6300 amps and a nominal frequency of 50/60 hertz is designed.
  • the circuit breaker 1 has a hollow cylindrical insulating body 2, which is flanged gastight between power terminals 3, 4.
  • the left part of the FIG. 1 shows the switch 1 in the open state.
  • the right part of the figure shows the switch 1 in the closed state.
  • the circuit breaker 1 comprises two contact arrangements, both of which are arranged in the switching chamber volume 5 delimited by the insulating body 2 and the two power connections 3, 4, movable relative to one another along the longitudinal axis A of the switch 1, and thus enable switching on and off of the switch 1.
  • the two contact arrangements have a consumable contact system 12 which is coaxially surrounded by a rated current contact system 9.
  • the consumable contact system 12 comprises the consumable contacts 10 and 11, while the rated current contact system 9 comprises the inner rated current contacts 6, the outer rated current contacts 7 and the counter nominal current contact 8.
  • One of the two contact arrangements has the burn-off contact 10 designed as a hollow cylinder, which is arranged along the switch longitudinal axis A, and the nominal current contact 8 surrounding the burn-off contact 11.
  • the rated current contact 8 is also cylindrical.
  • an insulating nozzle 13 for guiding a quenching gas stream for example Schwefelhexaflouridstromes (SF 6 ) is arranged, which insulating nozzle 13 projects beyond the rated current contact 8 and the AbbrandWallet 11 in the direction of the longitudinal axis A.
  • a heating channel 18 is formed which in a heating volume 16 opens.
  • the heating volume 16, which is essentially limited by the rated current contact 8, insulating nozzle 13 and consumable contact 11, is connected via a valve 19 to a compression volume 17 of the switch 1.
  • the other of the two contact arrangements comprises the arranged in the switching chamber volume 5 Abbrand token 10, the inner rated current contacts 6 and the outer rated current contacts 7.
  • the hollow cylindrical executed Abbrand token 10 is movable against the force of a spring 14 along the longitudinal axis A and is with the spring 14 in a tubular Section 20 out, which opens into an exhaust volume 13. Extinguishing gas can thus escape through the hollow Abbrandcard 10 in the exhaust volume 13.
  • the inner rated current contacts 6 are designed as elastic contact fingers and form a ring 22 of contact fingers, around which coaxial also designed as elastic contact fingers and also a ring 23 of contact fingers forming outer rated current contacts 7 are arranged.
  • the coaxial arrangement of the outer rated current contacts 7 to the inner rated current contacts 6 has the advantage that the number of Nennstromcriptor and thus the effective contact surface on the switch 1 can be increased by this structure, which in turn increases the current carrying capacity of the circuit breaker 1, but without the diameter or to increase the volume of the circuit breaker 1.
  • the current density per switch volume unit to be transmitted can thus be increased.
  • Both the ring 22 formed by the inner rated current contacts 6 and the ring 23 formed by the outer rated current contacts 7 are firmly connected in the switch 1 to a rated current contact carrier 21. Ring 22 and ring 23 are screwed onto the Nennstromterntragenia 21, whereby a simple replacement of the inner rated current contacts 6 and the outer rated current contacts 7 is achieved.
  • the inner rated current contacts 6 extend beyond the outer rated current contacts 7 in the direction of the longitudinal axis A and are the outer Rated current contacts 7 upstream.
  • Inner and outer rated current contacts 6 and 7 are electrically connected to each other.
  • FIG. 2a to Figure 2d show the in FIG. 1 described circuit breaker 1 in different switching states. So shows FIG. 2a the switch 1 in the switch position “off”, in the FIG. 2b the switch 1 in the switch position “Contacting burn-off contact system”, Figure 2c the switch 1 in the switch position "contact internal rated current contacts” and finally Figure 2d the switch 1 in the switch position "on”.
  • the circuit breaker 1 takes the switch position "contact internal rated current contacts", which in Figure 2c is shown.
  • the contact is defined by the moment of the first physical contact between the inner rated current contacts 6 and the opposite rated current contact 8.
  • the outer diameter of the ring 22 formed from the inner elastic rated current contacts 6 is so selected to the inner diameter of the trained as a hollow cylinder rated current contact 8, that the rated current contact 8 is pushed overcoming the contact force over the rated current contacts 6, whereby the inside of the Hollow cylinder formed rated current contact 8 the outside overlaps the ring 23 formed from rated current contacts 6 and touches.
  • the current commutates from the consumable contact system 12 to the rated current contact system 9, whereby the current flowing in the switch 1 is carried at this moment by the rated current contact system 9 and the consumable contact system 12 connected in parallel thereto.
  • the burn-off contact 10 is pressed against the spring force of the spring 14 and caused by the switch-on movement of the contacting burn-off contact 11 in the direction of the exhaust volume 16.
  • the rated current contact 8 driven by a drive, not shown, continues to move towards the inner and outer rated current contacts 6 and 7. In this way, the switch position "on" is achieved, as in Figure 2d shown.
  • the inner diameter of the ring 23 formed from the outer elastic rated current contacts 7 is here so selected to the outer diameter of the designed as a hollow cylinder rated current contact 8, that the inner rated current contacts 6 are pushed overcoming an additional contact force on the rated current contacts 8, whereby the inner side formed from rated current contacts 6 Ringes 22 the outside of the form of a hollow cylinder rated current contact 8 overlaps and touches.
  • the rated current contact 8 is thus clamped on the basis of the force exerted by the inner and outer rated current contacts 6 and 7 contact force between the inner and outer rated current contacts 6 and 7. Due to the same electrical resistance of the inner rated current contacts 6 and the outer rated current contacts 7, the current flow in the switch 1 is divided essentially over the inner and outer rated current contacts 6, and 7. In this case, the ring 23 of contacts formed by the outer rated current contacts 7 carries about 65% of the total current, while the ring 22 formed from the inner rated current contacts 6 carries about 35% of the current.
  • FIG. 3 The diagram shown qualitatively represents the forces acting on the inner and outer rated current contacts 6 and 7 and illustrates the resulting frictional force F R on the rated current contact system 9 which must be overcome by means of the drive in order to ensure the switch-on movement of the contact arrangements.
  • a frictional force (not shown) acts in the direction of the longitudinal axis A against the switch-on movement caused by the inner and outer rated current contacts 6, 7, which slide on the rated current contact 8.
  • An increasing electric current in the switch 1 also causes an increasing contact force between the outer rated current contacts 7 and the Gegennennstromtern eighth
  • the switch 1 is in the switch state "off" as in FIG. 2a shown.
  • the current flow of the contact arrangements is interrupted, the sum of the acting forces is zero.
  • the switch state "contact internal rated current contacts" as in Figure 2c shown, drive through.
  • a frictional force on the rated current contact system 9 occurs between the JacobnennstromWallet 8 and the inner rated current contact 6, through the electromagnetic force F I , which is reduced.
  • the force F I is caused by the current flow in the inner rated current contacts 6.
  • This electromagnetic force F I counteracts the contact force between rated current contact 8 and inner rated current contact 6.
  • the contact force and thus the resulting friction force F R between the rated current contact 8 and the inner rated current contacts 6 is reduced.
  • the resulting frictional force F R at current flow through the inner rated current contacts 6 is thus smaller than the frictional force that occurs when no current flows.
  • This commutation causes, on the one hand, that the electromagnetic force F I decreases at the inner rated current contacts 6 and at the same time an electromagnetic force F A acts on the outer rated current contacts 7, which increases the contact pressure of these contacts 7.
  • the resulting frictional force F R results from the contact force of the inner and outer rated current contacts 6 and 7 on the countercurrent contact 8 and a frictional force F R reducing component of the electromagnetic force F I caused by the current flow in the inner rated current contacts 6, and a frictional force F R increasing component of the electromagnetic force F A , caused by the current flow in the outer rated current contacts 7.
  • the electric current is divided across the rated current contacts 6, 7, so that about 65% on the external rated current contacts 7 and about 35% flows over the inner rated current contacts 6.
  • the presence of internal rated current contacts 6 in addition to the external rated current contacts 7 thus reduces the frictional force occurring at the contacts in comparison to the force that occurs in a Circuit breaker occurs, which has only such rated current contacts, which act from the outside to an internal Jacobnennstromnapse
