Definitions

  • the invention relates to an arrangement for sealing a cylindrical Oil vessel of a switch, preferably a load selector, diverter switch for tap changer or the like, one in the boiler, especially in the oil boiler Transformer is provided and the oil vessel consists of an insulating tube, whose two end faces each have a metal flange of a cover or base part are assigned with a seal, the metal flange being detachable Clamping elements that engage in an outer groove of the insulating tube with the Insulating tube is connected.
  • Such a sealing arrangement is known from AT-PS 341 624.
  • External groove has a rectangular cross-section into which a ring shoulder of a Engages metal ring.
  • This metal ring is over tension screws, which in a vertical threaded hole of the metal flange ends in the direction of Pulled the front of the insulating tube.
  • This will also be the sealing rings between the face of the insulating cylinder and the metal flange compressed.
  • a major disadvantage with this seal has been emphasized that due to the rectangular cross section of the outer groove an oversized thickness of the insulating tube must be selected.
  • the rectangular cross-section causes a notch effect in the edges Can cause damage and can be compensated for with material thickness got to.
  • the object of the invention is therefore to provide an arrangement of the type cited at the beginning to create, which on the one hand avoids the disadvantages indicated above and the on the other hand, rational production of such a switch is permitted.
  • the arrangement according to the invention is characterized in that the outer groove of the insulating tube in cross section is semicircular that in this semicircular outer groove Round clamping ring is arranged in cross section and that in the metal flange at least one that runs at an acute angle to the end face of the insulating tube Threaded bore is provided with a screw, the end face of the Screw acts on the clamping ring.
  • the semicircular outer groove in that facing away from its corresponding end face of the insulating tube Direction from the zenith to the outer circumference, especially at an angle trending, executed.
  • This allows the clamping ring, even if it is in one piece is easy to use.
  • This version also offers a good contact surface of the face of the screw on the clamping ring, since the Angle can be chosen relatively acute.
  • the clamping ring consists of two Parts, in particular from two interconnectable half rings. Also this construction contributes to the simpler and therefore faster assembly. In addition, manufacturing tolerances can be compensated more easily.
  • the screw is a Cylinder screw with a hexagon socket.
  • Such machine elements have proven their worth in practice and do not require enlargement the storage of spare or assembly parts.
  • 1 is an arrangement for sealing a cylindrical Oil tank of a load selector shown. Of course, this arrangement can Sealing can also be used when switching loads.
  • Gearbox drives the selector shaft with all moving contacts.
  • On Load selector combines the functions of a diverter switch and one Voters.
  • the advantages of a load selector are that universal as Star point switch, single pole switch or can be used as a delta switch. He has a simple mechanism, with all switching contacts made of sintered tungsten material can be produced. This choice of materials is one to achieve long contact life.
  • a load selector can also be separate Have continuous current contacts.
  • the drive shaft is or are and the flange connections are freely adjustable.
  • the load selector changes the levels directly during the dialing process. As soon as the motor drive starts, the transmission starts in the switch head Spring mechanism. After the complete opening, the lock is released the spring accumulator lifted and this actuates the movable Contact system of the load selector in quick changeover from the selected to the selected level.
  • the changeover time is approx. 40 to 60 ms.
  • This oil vessel consists of an insulating tube 1, being on its end face a metal flange 2 of a cover part is arranged.
  • the sealing takes place via a sealing ring 3 which between the end face of the insulating cylinder 1 and the metal flange 2 is provided.
  • This sealing ring 3 is, for example, in a ring groove 4 of the metal flange 2 specially dimensioned for him arranged.
  • the insulating tube 1 has an outer groove 5 in which a clamping ring 6 is arranged. Furthermore, in the metal flange 2 at an acute angle to the end face of the insulating tube 1, a threaded bore 7 is provided with a screw 8. The end face of the screw 8 acts on the clamping ring 6.
  • the clamping ring 6 can consist of two parts, in particular of two together connectable half rings.
  • the screw 8 a Socket head screw with a hexagon socket.
  • the outer groove 5 is in its corresponding Direction facing obliquely. This slant 9 also serves for easier assembly of the clamping ring 6.
  • the metal flange 2 is the seal of the metal flange 2, the bottom part Used, shown.
  • the metal flange 2 again has the annular groove 4 for the sealing ring 3, which is arranged on the end face of the insulating tube 1. Furthermore, the metal flange 2 has an acute angle to the end face of the Insulating tube 1 running threaded hole 7 with a screw 8. In the External groove 5, the clamping ring 6 is provided on the end face of the Screw 8 acts.
  • the bottom part can be vertical for easier emptying of the oil container Have holes 10.
