Definitions

  • the invention relates to an electrical high-voltage circuit breaker with a drive at ground potential and with at least one insulating switching rod for transmitting the drive movement to a high-voltage potential breaker unit by axial pressure or tension.
  • High-voltage circuit breakers usually have two switching contacts, which are galvanically connected to one another in the switched-on state and are separated from one another when the switch is opened. Since the opening movement is to take place at high speed and, at the same time as the switching contacts are often to be actuated, a mechanical compression device for generating an extinguishing gas flow is also to be actuated, large drive forces are necessary to actuate such a high-voltage circuit breaker. As is known, for example, from the technical article "Siemens Bk switch, a new generation of SF6 switches", Siemens magazine 47 (1973), number 4, p.
  • the drive device of a high-voltage circuit breaker is usually arranged at ground potential, while the actual interrupter unit, which contains the switch contacts, is normally at high voltage potential.
  • the driving force must now be transmitted between these two units by means of an insulating medium, usually a shift rod.
  • the present invention has for its object to monitor the state of the switching rod in an electrical high-voltage circuit breaker of the type mentioned in order to ensure the safe functioning of the circuit breaker guarantee and arrange for maintenance if the shift rod is defective.
  • a first device is provided on the first end of the shift rod facing the interrupter unit, which generates an axial movement of the first end of the shift rod a rotational movement of this end about the longitudinal axis of the shift rod and that on the second facing the drive
  • a second device for monitoring the rotary movement of the shift rod is provided at the end of the shift rod.
  • the shift rod is actuated, be it in the pulling or pushing direction, then, if it is not defective, the first end is rotated a little by the first device.
  • a torque is exerted on the shift rod so that, depending on the counter torque exerted on it, it also rotates a bit at its second end.
  • This rotation of the second end of the shift rod indicates firstly that the pulling or pushing movement of the shift rod has continued from the drive to its first end and secondly that the rotational movement of the first end of the shift rod has been transmitted back to the second end of the shift rod .
  • the second device can be arranged in the area of the drive at ground potential.
  • a particularly advantageous embodiment of the invention provides that the first device is designed as a link guide.
  • either a link can be fixed to the switch housing and the first end of the switch rod can carry a bolt guided in the link.
  • the backdrop would then have to be helical around the shift rod.
  • the link is connected to the first end of the switching rod and a corresponding bolt is fastened to the encapsulation of the circuit breaker.
  • an external thread with a large pitch is provided at the first end of the shift rod and that the first device has a corresponding internal thread.
  • a signal emitted by the second device regarding the position of the switch rod is compared with the desired state of the circuit breaker and that a signal is emitted if these values differ from one another.
  • the figure shows schematically an interrupter unit and a drive of a high-voltage circuit breaker.
  • the circuit breaker is driven by a hydraulic drive unit 1 with a drive rod 2.
  • An induction element 3 is provided on the drive rod 2 and emits a signal to a proximity switch 4 when the drive rod 2 moves.
  • the proximity switch 4 is connected to measuring electronics 5, which registers the movement of the drive rod 2 by the response of the proximity switch 4 and forms a signal about the desired switching state of the interrupter unit.
  • the movement of the drive rod 2 is converted into a corresponding pushing or pulling movement of the shift rod 7 via a stationary crank 6.
  • the crank 6 is connected to the shift rod 7 via an articulated rod 22.
  • the pushing or pushing movement of the switching rod 7 is transmitted to the interrupter unit 8, whereby the contact between the lines 9, 10 is switched on and off, respectively.
  • the interrupter unit 8 and the switch rod 7 and possibly also the articulated rod 22 are enclosed gas-tight by an encapsulation 11 which contains an insulating gas, for example SFtown.
  • the crank 6 can also be arranged within this encapsulation 11.
  • the shift rod 7 is axially guided in several places, which is indicated, for example, by the axial guide 12.
  • the shift rod 7 is divided into three parts 13, 14, 15, which are mutually rotatable about the longitudinal axis of the shift rod 7.
  • roller bearings 16, 17 are provided between the parts, which allow such rotation with little resistance and at the same time are able to transmit a tensile or compressive force.
  • a bolt 18 is fastened, which projects radially outward from the shift rod 7 and engages in a slot 19 of a sheet which is firmly connected to the encapsulation 11.
  • the slot 19 is formed helically surrounding the shift rod 7 coaxially.
  • a pivot arm 20 is fastened with an induction element, which performs a corresponding pivoting movement when the shift rod 7 rotates. This is registered by an inductive probe 21 which is connected to the measuring electronics 5.
  • the first device 18, 19 is arranged as close as possible to the interrupter unit 8, so that when the Switching movement between the location of the link guide 18, 19 and the interrupter unit 8 are as few sources of error as possible.
  • the measuring electronics 5 can then compare the signals received from the probe 4 and the probe 21 with one another and determine whether the desired state of the interrupter unit 8 (switching state of the drive unit) corresponds to the actual state. If this is not the case, the switch is shut down and must be maintained.
