Definitions

  • the invention relates to an insulating housing, in particular housing a switching tube of a vacuum switch, with at least one holder, which is arranged on an outer wall of the insulating housing and positioned there an electric field influencing, annular control electrode.
  • Such an insulating housing is for example from the DE 297 17 489 U1 refer to.
  • the local insulating housing is substantially hollow cylindrical and surrounds two axially opposite contacts coaxially.
  • the two end portions of the hollow cylindrical insulating housing are sealed gas-tight with end plates.
  • the connecting pins of the contact pieces are guided gas-tight, wherein a connecting bolt is fixedly mounted on one of the contact pieces and the other contact pin is movably passed through one of the end plates.
  • a shield electrode is also arranged coaxially to the switching pieces.
  • the hollow cylindrical insulating housing is composed of two partial bodies. In the joint of the two adjoining part body, the shield electrode is held.
  • An insulating housing with a soldered annular control electrode is made of EP-A-0411492 known.
  • the present invention is therefore based on the object to enable a simpler and more cost-effective mounting of the electrodes to an insulating housing.
  • the at least one support has contact surfaces, which are arranged distributed on a circumference of the insulating housing and are arranged to each other, that the contact surfaces form a receptacle in which the annular control electrode form-fitting is determinable.
  • the holder is made of a metal.
  • the control electrode is sufficiently electrically contacted with the holder, so that holder and control electrode have the same electrical potential.
  • the holder can be arranged in any way on the insulating housing. Thus, for example, this may extend in the manner of a clamp around the insulating housing or be incorporated in the insulating housing or engage in correspondingly shaped Isolierköperabroughe.
  • annular control electrode is the formation of the control electrode as a circular ring.
  • oval-shaped or polygonal ring-shaped control electrodes can also be positively inserted into the receptacle formed by the contact surfaces.
  • individual contact surfaces are arranged along the circumference mutually v-shaped.
  • V-shaped arrangement of individual pressure surfaces to each other represents a technically simple construction.
  • V-shaped contact surfaces allow each of the contact surfaces thus formed determines the annular control electrode both in the axial direction and in the radial direction.
  • Exemplary embodiments are two circumferential on the circumference of the insulating V-shaped to each other arranged Anspress vom, so that a V-shaped annular groove is formed or the arrangement of a few contact surfaces along the circumference, which are arranged v-shaped to each other, and so the annular control electrode only selectively support and position.
  • An advantageous embodiment may further provide that the V-shaped pressing surfaces are offset along the circumference.
  • the V-shaped contact surfaces are arranged directly opposite each other.
  • the contact surfaces can also be arranged offset from each other along the circumference. This makes it possible, for example, in a waiver of any second contact surface to construct the holder material-saving and still the advantageous embodiment of the receptacle for positive fixing to maintain the annular control electrode. Despite this offset, a sufficient mechanical strength of the holder and the annular control electrode fixed thereto can be achieved.
  • a further advantageous embodiment of the invention provides that the at least one holder has comb-like teeth, of which a first group is bent perpendicular to the circumferential direction and a second group is opposite to the first group bent so as to form the contact surfaces.
  • the contact surfaces form a ringnutähnliche recording on the circumference of the insulating housing.
  • annular groove-like receptacle on the circumference of the insulating housing, which is formed by the contact surfaces, represents a very favorable possibility to fix the annular control electrode in a form-fitting manner.
  • the recording does not need to be a conventional complete annular groove.
  • individual sections such as three symmetrically distributed on the circumference of the pressure surfaces and possibly three associated thereto v-shaped staggered contact surfaces also have the necessary functionality of a by the contact surfaces formed receptacle for positioning the annular control electrode.
  • control electrode for inserting into the receptacle is elastically deformable.
  • the elastic deformability represents a favorable alternative to a rigid control electrode.
  • An elastically deformable control electrode is particularly easy to insert into a receptacle.
  • Such an elastically deformable control electrode adapts to the recording in a favorable manner and secures independently in their position.
  • a multi-part design of the control electrode is possible. The individual sections are inserted into the receptacle and connected there. Combinations of rigid control electrode sections with elastic sections to achieve favorable mounting conditions are constructible. Alternatively or additionally, the recording can be carried out limited elastic.
  • the insulating housing is formed from at least two adjoining partial bodies, then it is favorable to use the resulting joint for holding the holder on the insulating housing.
  • the two contiguous partial bodies can be both two partial bodies formed from insulating material as well as one insulating partial body and one electrically conductive partial body.
  • the part of the body may also be both electrically conductive part body, which are part of the parent insulating housing. Additional recording devices on the insulating can be bypassed so.
  • Such joints are still disturbing arrangements that can affect in particular the homogeneity of the electric field. For this reason, such joints should be particularly electrically shielded.
  • An advantageous design can provide that the at least one holder in the interior of the insulating housing holds a shield electrode.
  • FIG 1 is shown as an example of an insulating housing a interrupter 1 of a vacuum switch.
  • the interrupter 1 has a first ceramic insulator 2 and a second ceramic insulator 3.

  • the second connecting bolt 8 is movably guided through a second end plate 10 in a gastight manner.
  • a bellows 29 is arranged on the second end plate 10.
  • the second connecting bolt 8 can be driven in the direction of the double arrow 30 by means of a drive.
  • a first shield electrode 25a, a second shield electrode 25 and a third shield electrode 26 are arranged on the first ceramic insulator 2 and a fourth shield electrode 27, a fifth shield electrode 28 and a sixth shield electrode 28a on the second ceramic insulator 3.
  • the first shield electrode 25a, the second shield electrode 25 and the third shield electrode 26 extend inside the interrupter tube 1 coaxially around the first terminal stud 7.
  • the fourth shield electrode 27, the fifth shield electrode 28 and the sixth shield electrode 28a are arranged coaxially with the second terminal stud 8.
  • the shielding electrodes are substantially hollow cylindrical. To avoid acute-angled arrangements, the free ends of the shielding electrodes are curved inwards.
  • a first holder 11, a second holder 12, a third holder 13, a fourth holder 14, a fifth holder 15 and a sixth holder 16 are inserted.
