Definitions

  • Instrument transformers for use in a gas-insulated high-voltage switchgear have an active part arranged in a fluid-tight housing, which is connected, on the one hand, to the switchgear and, on the other hand, to an evaluation unit.
  • the connection between the active part and the switchgear must be disconnected, as otherwise the active part could be damaged.
  • single-phase transducers with an active part in a housing and multiphase, usually three-phase, transducer having a plurality of rotationally symmetrically arranged in the housing active parts known.
  • various separation devices are known.
  • the EP 2 144 261 A1 describes a gas-insulated transducer according to the preamble of claim 1.
  • the object of the invention is to provide a transducer with multiple active parts with an improved separator.
  • a gas-insulated transducer which serves to measure high voltages, is provided for this purpose.
  • the transducer has a plurality of transducer assemblies arranged in a fluid-tight housing for converting a high voltage into a measured voltage.
  • Each transducer assembly includes an active part, a high voltage contact passed through the housing, a fixed contact electrically connected to the active part, and a movable contact electrically connected to the fixed contact.
  • the transducer also includes an operable from outside the housing separating device by means of a connection of the movable contacts with the high-voltage contacts can be produced or separated.
  • the separating device has a connecting element which interconnects the movable contacts and adjusting means for moving the connecting element in a setting direction. A transmitted to the connecting element by means of the adjusting movement thus leads to a synchronous movement of the movable contacts in the direction of adjustment.
  • the fixed contact is designed as a guide for the movable contact in the direction of adjustment.
  • the movement is preferably a linear movement and the guide is designed as a linear guide.
  • the guide may be formed, for example, in the form of tongue and groove, as a dovetail guide, as a rail guide, as a rolling guide, as a sliding bearing guide or as a telescopic guide.
  • a good electrical contact between movable contact and fixed contact is established by the guide.
  • the guide is used to allow the movement of the movable contact in the direction of adjustment and to restrict a movement in the direction perpendicular to the direction of adjustment.
  • the fixed contact on a tubular end and the movable contact on a rod-shaped end, the rod-shaped end is inserted into the tubular end.
  • the electrical contact can be made for example by spring or lamellar contacts.
  • the adjusting means comprise a connecting rod connected to the connecting rod, which is movable by means of a drive arranged outside of the housing in the adjusting direction.
  • the push rod transmits the movement of the drive on the connecting element, which in turn transmits its movement to the movable contacts, whereby a particularly simple manner, a synchronous movement of the movable contacts is achieved.
  • the drive is coupled to the push rod via a transmission which converts a rotary movement of the drive into a linear actuating movement of the push rod.
  • the transmission is preferably arranged in the interior of the housing and may for example be an eccentric, a worm gear or a trapezoidal thread gear.
  • the drive transmits a rotating movement into the interior of the housing, which is converted there into a linear movement.
  • this reduces the space required for the drive, on the other hand, a rotating movement is easier to guide gas-tight through the housing wall, as a linear.
  • the transmission is designed as an eccentric, since this is particularly simple in construction and mountable.

  • the rod-shaped end 13 is almost completely inserted into the tubular end 12, as indicated by the dashed lines.
  • the contact pieces 14 now have a distance from the high-voltage contact 6, the electrical connection from the high-voltage contact 6 to the primary windings of the active parts 9 is thus separated.

  • a connecting element 15 Perpendicular to the connecting element 15, one or more push rods 16 is connected to the connecting element 15.
  • the push rod 16 is coupled to a separation mechanism explained below, by means of which the push rod 16 is movable perpendicular to the winding axis 40. The movement of the push rod 16 is transmitted to the connecting element 15, this transmits the movement to the movable contact eleventh
  • the connecting webs 27 extend parallel to the winding axis 40.
  • the fixed contacts 10 pierce these connecting webs 27 and are fixed in these.
  • the push rod 16 extends between each two fixed contacts 10 either in the space between two connecting webs 27 between them or pierces the connecting webs 27 through an opening in this.

  • the FIG. 4 shows a part of the FIG. 2 like these in the back view, the FIG. 5 a similar section of the same transducer 1, but with respect to the FIG. 4 in the front view.
  • the separation mechanism consists of a gear 17, which is here an eccentric gear, and at least one drive shaft 22 which is coupled to the gear 17.

  • the drive 7 may be, for example, a manual drive or an electric motor drive.
  • the drive 7 may also include a transmission.
  • the drive shaft 22 can be placed in a rotating movement.
  • the drive shaft transmits this movement to an eccentric 17, which converts the rotating movement into a linear movement.
  • the eccentric 17 has an eccentric 18 and an eccentric 19.
  • One end of the drive shaft 22 is connected to a central axis 24 of the eccentric disc 18.
  • the second end of the drive shaft 22 is connected to the drive 7.
  • Eccentric to the central axis 24, an eccentric axis 21 is arranged on the eccentric disc 18.
  • the eccentric arm 19 is rotatably mounted with a first end on this eccentric axis 21.
  • a second end of the Exzenterarms 19 is rotatably coupled via a coupling pin 20 with the push rod 16.
  • the push rod 16 is limited by the guide sleeve 30 to vertical movements.
  • a transmitted by means of the drive 7 to the drive shaft 22 rotation is transmitted to the eccentric disc 18.

The push rod 16 is moved upward in the direction of the eccentric disc 18. The push rod 16 transmits this vertical movement via the movable beam to the movable contacts 11, which are thereby moved away from the high-voltage contact 6. The electrical connection between high voltage contact 6 and movable contact 11 is thereby separated, thus the primary windings are separated from the high voltage. Another rotation of the drive shaft 22, regardless of which direction, leads to the opposite movement of the push rod 16 and restores the connection with a rotation of 180 °.

  • the rod-shaped ends 13 of the movable contacts 11 are guided in the tubular ends 12 of the fixed contacts 10 for protection against tilting.
  • the transducer 1 has two eccentric 17, which are each driven by a drive shaft 22.
