Definitions

  • the invention relates to an arrangement for a high-voltage circuit breaker with at least one movable electrical contact piece of an interrupter unit, the at least one movable contact piece being arranged on a switching rod, and to a method for driving the at least one movable electrical contact piece, the contact piece being moved over the switching rod ,
  • An example of high voltage circuit breakers is shown in the DE-U-29824462 disclosed.
  • High-voltage circuit breakers are used to switch high voltages and currents, in particular in the range from up to a few 10,000 V and up to a few 1,000 A.
  • an interrupter unit comprises electrical contacts, e.g. a nominal current and / or an arcing contact, each with two contact pieces, or only one contact, with two nominal current contact pieces.
  • a first contact piece of the respective contact can be spatially fixed and a second contact piece of the same contact can be arranged movably in the circuit breaker.
  • Both contact pieces for electrical switching on and off can also be arranged to be movable.
  • Essential for the switching process i.e. electrically disconnecting or connecting the contact, is the relative movement of the two contact pieces of a contact towards or away from each other.
  • High-voltage circuit breakers can contain a switching gas, eg SF 6 , or be constructed in the manner of a vacuum tube.
  • the interrupter unit is surrounded by a housing and the housing is sealed or sealed against the environment.
  • the gas-tight housing is filled with switching gas or evacuated to create a vacuum in the housing. The effect of the switching gas or vacuum makes the burning an arc between the contact pieces inhibited when switching and / or extinguished.
  • the movable contact piece (s) are connected via a kinematic chain e.g. mechanically connected to a gear and / or a drive.
  • a drive can e.g. be designed in the form of a motor or a spring accumulator, and provide mechanical energy when switching for the movement of electrical contact pieces.
  • a switching rod as part of the kinematic chain can be used to transfer the kinetic energy into the housing on the movable contact pieces.
  • the switch rod is connected to the movable contact pieces in the housing, directly and / or via e.g. Lever elements, gear parts and / or other deflection devices.
  • the object of the present invention is to avoid or reduce the problems described above.
  • it is an object to provide an arrangement for a high-voltage circuit breaker, which has fewer components or elements than conventional arrangements for driving movable contact pieces of the interrupter unit of the high-voltage circuit breaker, causes lower costs, and has a higher reliability and durability.
  • the task is to transfer the kinetic energy from the outer area to the inner area of the vacuum tube via a switching rod, while ensuring the long-term stable tightness of the vacuum tube, in particular sealed with a bellows, without damaging or destroying the bellows over time due to pendulum movements the shift rod.

  • An arrangement according to the invention for a high-voltage circuit breaker comprises at least one movable electrical contact piece of an interrupter unit, the at least one movable contact piece being arranged on a switching rod.
  • the switch rod is movably mounted between the outer region and the inner region of the housing of the interrupter unit, with an exclusively linear guidance of the switch rod.
  • the storage of the shift rod with an exclusively linear guide prevents or prevents pendulum movements of the shift rod.
  • the suppression of pendulum movements of the shift rod ensures long-term tightness without damage or destruction of the bellows over time.
  • Kinetic energy is transmitted via the switch rod from the outside to the inside of the high-voltage circuit breaker without using rotary unions.
  • Rotary unions generally have a large number of parts or elements and are difficult to seal gas-tight, especially when there are high pressure differences of several bar between the outside area and the inside area.
  • the linear guidance of the shift rod can include an anti-rotation device.
  • This can e.g. be formed by a movable body which is linearly movable in a groove.
  • a linear or straight groove results in a linear movement of the body in the groove, and the rigid connection of the body to the shift rod prevents rotation of the shift rod about its longitudinal axis.
  • two bodies which are opposite one another on the shift rod and are arranged on opposite sides of the shift rod and are movably arranged in two mutually opposite grooves.
  • more than two body-groove pairs can also be used and / or a plurality of bodies, in particular rigidly connected to the shift rod, can be arranged in a groove.

  • the shift rod can also be rectangular instead of round, for example, and run in the groove as in a rail. For this purpose, the shift rod can have a larger diameter in the area of the groove than in other areas along its longitudinal axis.
  • the interrupter unit can be a vacuum interrupter unit in a vacuum tube, in particular with at least one nominal current contact with two nominal current contact pieces each and with at least one arcing contact with two arcing contact pieces each. Alternatively, only nominal current contact pieces can be used.

  • the construction described requires a small installation space and saves costs and material.
  • the sealing function can be integrated in the support foot and a linear guide in the support foot ensures a better and long-term stable seal achieved because a pendulum movement in the area of the seal in the support foot is avoided.
  • At least one slide bearing can be arranged in the area of the linear guidance of the shift rod.
  • the plain bearing reduces friction losses and enables the shift rod to move with less force than without a plain bearing.
  • the inner region of the housing of the interrupter unit can be sealed in a gas-tight manner with respect to the outer region via the switching rod and a sealing element arranged between the switching rod and the housing, in particular with a bellows as sealing element.

  • the sliding sleeve reduces friction between the switching rod and the support foot and thus reduces the effort required to move the switching rod and switch the high-voltage circuit breaker.
  • the drive can thus be made smaller and more cost-effective.
  • a bellows for gas-tight sealing of the inner region of the housing of the interrupter unit from the outer region can be arranged between the switch rod foot and the cylindrical recess of the support foot of the high-voltage circuit breaker, in particular gas-tightly attached to the cylindrical recess of the support foot on one side towards the interrupter unit and / or gas-tight attached to the shift rod foot on the opposite side, especially on the side of the cylindrical body.
