Definitions

  • the invention relates to a fully solid-insulated vacuum switch (so-called 'switch pole') with two connections and an insulating housing, which carries an outer grounded coating and has a vacuum interrupter inside, gas being located between the interrupter and the insulating housing.
  • a fully solid-insulated vacuum switch switch pole'
  • Such vacuum switches with full solid insulation are preferably required for factory-made high-voltage switchgear or transformer stations, where there are high requirements with regard to protection against accidental contact and with regard to small-scale and compact construction.
  • vacuum interrupters in switching devices which consist of an evacuated housing with a fixed and a movable contact piece and metal shields.
  • Switches with oil in the intermediate space in turn have similar disadvantages to the so-called low-oil switches because they pose a fire risk and endanger the environment. Furthermore, it is known to pour the complete vacuum interrupter in - epoxy resin (DE-OS 22 40 106). However, there are disadvantages because internal mechanical stresses acting on the vacuum interrupter are unavoidable, and cracks as well as air gaps and air inclusions cannot be reliably excluded, in which the formation of destructive partial electrical discharges then occurs.
  • the solid-air-insulated vacuum switches described above also have the additional disadvantage that they must not be touched during operation, and therefore, for reasons of the necessary protection against accidental contact, installation can only take place in metal-enclosed switch cells, or additional shut-offs are required.
  • This disadvantage can be known simultaneous reduction in dimensions can be overcome if the principle of full solid insulation is applied, according to which the entire high-voltage current path and all built-in devices are embedded in solid insulating material, on the surface of which a grounded metallic shielding is attached (Elektrie "28.Jhrg. (1974 ), Issue 10, pp. 533 - 538).
  • the invention is based on the finding that it is important in the improvement of such vacuum switches according to the preamble of claim 1 to avoid partial discharges in the area between the switching chamber and the insulating material housing or in the insulating material housing itself by avoiding extremely high field strengths and short distances and protection against accidental contact To shift the electrical stress into the solid insulation.
  • the invention is accordingly based on the object of developing a vacuum switch according to the preamble of claim 1 so that partial discharges can be reliably avoided despite the arrangement of the vacuum interrupter in an insulating housing with a grounded coating in the gas-filled space between the interrupter and the insulating housing.
  • the vacuum interrupter 1 is accommodated in an upper, fully solid-insulated cylindrical insulating body 12 and in a lower, fully solid-insulated cylindrical insulating body 13, which form an insulating housing.
  • the insulator 12 and 13 on carry an earthed metal covering 14 on their outer surface, are connected in a dielectrically tight manner by means of an elastic insulating ring 15 via clamping elements 16, the lateral squeezing of the elastic insulating ring 15 being prevented by an inner and an outer metallic limiting ring 17 and 18.
  • An upper control electrode 19 with the potential of the upper contact 11 and a third control electrode 20 with the free intermediate potential of the metal screen 9 of the vacuum interrupter 1 are cast in the upper fully solid-insulated insulating body 12 such that the control electrode 19 is spatially between the grounded metal coating 14 and the control electrode 20 .
  • the upper control electrode 19 can simultaneously serve for the mechanical attachment of the vacuum interrupter 1 to the upper, fixed contact rod 3, for example via threads.
  • the upper contact rod 3 is pushed through the upper solid-insulated insulating body 12 to create the upper connection.
  • the control electrode 19 is expediently made from a rotationally symmetrical sheet metal body and from a thick-walled cup-shaped base body, so that, in a known manner, favorable heat dissipation from the vacuum interrupter chamber 1 into the upper, fully solid-insulated insulating body 12 is made possible, from where the heat can be given off to the ambient air.
  • the lower control electrode 22 with the potential of the lower connection is located in the lower fully solid-insulated insulating body 13; which consists of the lower contact rod 5, the sliding contact 10 and the switch lead 21, and the third control electrode 20 with the free intermediate potential of the metal screen 9 cast in such a way that the control electrode 22 is spatially between the grounded metal coating 14 and the control electrode 20.
  • the axially movable lower contact rod 5, to which a suitable drive is coupled, is inserted into the sliding contact 10, which is connected to the switch connecting conductor 21 cast into the lower, fully solid-insulated insulating body 13.
  • the sliding contact 10 can also give the vacuum interrupter 1 guidance against radial offset by suitable shaping.
  • the control electrode 22 is in turn expediently made of a rotationally symmetrical sheet metal body and a thick-walled annular base body, so that, in a known manner, favorable heat dissipation from the vacuum interrupter chamber 1 and the sliding contact 10 occurs in the lower fully insulated insulating body 13, from where the heat can be given off to the ambient air .
  • Fig. 2 shows a vacuum switch with an insulating housing, the housing parts are connected by gluing and in which the electrodes articulated to the connection potential have a smaller diameter in the overlap area than the third control electrode.
  • the complete vacuum interrupter chamber 1 is provided in the same way as in FIG. 1 in a lower and an upper fully solid-insulated insulating body 12 and 13 and is connected to the sliding contact 10 and the control electrodes 18 and 22.
  • control electrodes 19 and 22 with the potential the switch connections and the control electrode 20 with the free intermediate potential of the metal screen 9 are cast into the fully solid-insulated insulating bodies 12 and 13 so that the control electrodes 19 and 22 are spatially between the grounded metal coating 14 and the control electrode 20.
  • the tax electrodes 19 and 20 then need only consist of the thick-walled cup-shaped or ring-shaped base bodies.
  • Fig. 3 shows a vacuum switch with an insulating housing, which consists of three detachably interconnected parts, in which the electrodes articulated to the connection potential at least partially consist of coverings which are applied to separately manufactured insulating material parts which are coaxially joined together.
  • the insulating housing consists in particular of an upper, fully solid-insulated cylindrical insulating body 12, a middle, fully solid-insulated cylindrical insulating body 24 and a lower, fully solid-insulated insulating body 13.
  • the insulating bodies 12, 13 and 24, which have a grounded metal coating 14 on their outer surface, are made of elastic insulating material rings 15 Dielectrically tightly connected to one another via clamping elements.
  • the upper insulating body 12 in turn consists of two individual parts 25 and 26 cast from casting resin, which, by means of semiconducting or conductive coatings, form part of the control electrode 27 on one part of their surface, which is closed at one end by an electrode ring 28, while the other end is applied to a further control electrode 19 which is at the connection potential.
  • the control electrode 19 expediently consists of a rotationally symmetrical, thick-walled cup-shaped base body, so that, in a known manner, favorable heat dissipation from the vacuum interrupter chamber 1 into the upper, fully solid-insulated insulating body 12 is made possible, from where the heat can be given off to the ambient air.
  • the middle insulating body 24 carries a substantial part of a control electrode 29 on its inner circumference.
  • the lower insulating body 13 also consists of two individual parts 30 and 31, which, by means of semiconducting or conductive coatings, form part of the control electrode 32 on part of their surface, which in turn also forms part of the control electrode 32 an electrode ring 33 is closed, the control electrode 32 also being articulated to the connection potential.
  • the third control electrode 29 consists essentially of the coating on the central insulating body 24 and of small coating surfaces 34 and 35 on the individual parts 30 and 31. The coatings are connected to one another and to the metal screen 9.
