Definitions

  • the present invention relates generally to electrical circuit breakers, and more particularly to dual power electrical circuit breakers.
  • the invention also relates to methods of contact separation in an electrical circuit breaker.
  • Switches in which a consumable contact, such as a quenching tulip, for separating an electrical connection from a further consumable contact, such as a pen, is moved away are known in the art. Switches are also known in which two burn-off contacts are moved in the opposite direction.
  • a gas blast switch with two oppositely movable contact pieces is described.
  • the contact pieces are coupled together via the insulating material nozzle and a lever mechanism.
  • the lever mechanism comprises a arranged on the switch axis two-armed lever with hinged on both sides connecting rods.
  • a high-voltage circuit breaker is described with a first arcing contact driving drive and a second arcing contact driving auxiliary drive.
  • the auxiliary drive comprises three two-armed levers and is designed such that during a switch-off operation, the direction of movement of the drivable second arcing contact piece is reversible once or twice.
  • Object of the present invention is to provide an improved dual drive for a circuit breaker.
  • the object is achieved by the electrical circuit breaker according to independent claim 1 and by the method according to independent claim 13. Further advantages, features, aspects and details of the invention as well as preferred embodiments of the invention will become apparent from the dependent claims, the description and the figures.
  • an electrical circuit breaker with special double movement of the contacts typically comprises a first contact piece with a first burnup contact, in particular a tulip, and a second contact piece typically with a second burnup contact, in particular a pin.
  • the circuit breaker further comprises a drive for moving the first contact piece in a first movement range along a switching axis, ie substantially parallel or anti-parallel to the switching axis, in particular relative to a housing, and a transmission for transmitting the movement of the first contact piece to a movement of the second contact piece.
  • the first range of motion includes a contact portion and a separation portion.
  • the Abbrandcarde s in contact ie a mechanical and electrical contact is provided when the first contact piece is in the contact portion, and they are mechanically separated from each other, ie, this is provided when the first contact piece in the separation portion located.
  • the gear has a first dead position, which is traversed in the directed in particular in one direction along the shift axis movement of the first contact piece in the contact portion.
  • the gear parts are dimensioned and arranged so that the first dead center is traversed.
  • a dead center is present when there is substantially no movement of the second contact piece during movement of the first contact piece.
  • a dead center is already present if this is fulfilled for (infinitesimal) small movements of the first contact piece about a position in the first movement range, ie in a linear approximation.
  • there is a dead center when the first derivative of a lift curve, such as in Fig. 3b is shown, disappears.
  • reversal points of the transmission ie extremes of the lift curve, dead spots.
  • a dead center of the transmission is usually also a dead position of a transmission part or transmission joint. Such dead position of a transmission part or transmission joint is present when there is substantially no movement of the transmission part or the transmission joint during movement of the drive side directly upstream of the transmission part.
  • the first dead center is in embodiments a reversal point for the pivotal movement of a preferably two-armed lever about its lever axis.
  • the first dead center is also characterized in embodiments by a substantially right angle between a drive rod and the shift axis.
  • a method for opening a contact of an electrical circuit breaker ie in particular for separating its Abbrandcarde
  • the circuit breaker comprises a first contact piece with a first contact, in particular Abbrand token, a second contact piece with a second contact, in particular Abbrandcard, and a transmission.
  • the method comprises the following steps: the first contact piece is moved in a separating direction along a switching axis; the transmission transmits the movement of the first contact piece to a particular associated therewith movement of the second contact piece along the shift axis; and the first contact and the second contact are separated by the movement of the contact pieces.
  • the particular assigned movement of the second switching piece changes before disconnecting the contacts at least once, in embodiments even at least twice or three times, the direction, in particular by a first dead center of the transmission is passed through.
  • the movement of the first contact piece comprises in embodiments an acceleration phase and then a movement phase, preferably at a substantially constant speed
  • the movement of the second contact piece comprises a pre-acceleration phase which lasts until at least one or two or three changes of direction are completed or are then followed by an acceleration phase, which is characterized by a speed of the second contact piece to about 50% of its maximum speed, and then a movement phase.
  • the acceleration phase of the second contact piece usually begins after the end of an analogously defined acceleration phase of the first contact piece.
  • the burn-off contacts are separated in embodiments only after the end of the acceleration phase of the second contact piece.
  • An advantage of a dead center in the contact portion is that the speed of the second contact can be kept low at least temporarily before the contact separation. Movement of the second high-speed contact piece may be limited in embodiments of the invention to a period in which such movement is advantageous or necessary (usually only after contact separation). As a result, drive energy can be used efficiently or space can be saved. Also wear by friction can be reduced. This also applies accordingly to the reverse movement when closing the contact between the contact pieces.

Therefore, regardless of the embodiment shown, it is proposed that the drive lever arm 53 and the output lever arm 54 are bent. Irrespective of this, the bent angle is preferably selected so that, during the movement of the first contact piece 10 in the first movement range, the dead position 62c and optionally the dead positions 62b and / or 62d (FIG.

  • the horizontal axis may also be in accordance with the inscription in FIG Fig. 3a to 3d be considered as a timeline. Specifically, this approximation is valid only after the end of a short initial drive acceleration phase during which the first contact is accelerated to the substantially constant speed. As the end of the drive or the output acceleration phase, the point can be set, from which the corresponding contact piece is accelerated to about 50% of its maximum speed. From this point, a movement phase of the corresponding contact piece, which is preferably characterized by a substantially, that is, to a tolerance of up to 50%, constant speed begins.
  • the points 62a to 62f respectively correspond to those in FIGS FIGS. 2a to 2f illustrated states of the transmission.
  • the lift curve 62 of Fig. 3a shows that the deflection of the second contact piece 20 in an initial phase is almost constant (part of the lift curve 62a-d), and that the second contact piece 20 is thus initially almost stationary.

  • the acceleration phase of the first contact piece 10 can be separated in time from the acceleration phase of the second contact piece 20. This is possible if the acceleration phase of the second contact piece 20 begins only after the end of the acceleration phase of the first contact piece 10. This can prevent the drive for the first contact piece 10 from having to accelerate two contact pieces 10, 20 simultaneously, and the acceleration energy of the drive can be used more advantageously. At the same time when closing the switch 1, ie in the reverse movement, the relative movement of the contact pieces 10, 20 are braked gently, which can reduce the material wear of the contact pieces 10, 20.
  • the acceleration can be increased. Also, due to the smaller deflection of the second contact piece 20 during the pre-acceleration phase, the range of movement of the second contact piece 20 necessary for switching is reduced, as a result of which a more compact design of the switch can be realized.
  • the Abbrandcarde 12, 22 are separated only during or even after the end of the acceleration phase of the second contact piece 20. As a result, it can be ensured that the relative speed of the contact pieces 10, 20 during disconnection of the electrical contact is high. As a result, an arcing occurring during separation is rapidly drawn and can thus be more easily deleted.
