Definitions

  • the invention relates to a resistance device for high-voltage systems with cylindrical resistance elements of different diameters stacked on top of one another in the same axis and connected to one another with disk-shaped contact elements, an inner resistance element with a smaller diameter being nested between each two axially adjacent outer resistance elements with a larger diameter is that each disc-shaped contact element has an indentation open on one side for receiving an inner resistance element and an indentation open on its other side for receiving an outer resistance element.
  • the outer resistance elements are each annular, while the inner resistance elements are formed by a 'compact circular cylinder.
  • the electrical connection between electrically successive resistance elements takes place by means of disk-shaped contact elements, wherein successive contact elements in the axial direction are galvanically separated from one another by insulating disks.
  • the stack of resistance elements and disk-shaped contact elements is apparently held together by means which are arranged outside the stack.
  • the invention is based on the object of proposing a resistance device for high-voltage systems which not only has a relatively small space requirement in the axial direction but also in the radial direction and which is distinguished by a high mechanical strength.
  • the inner resistance elements like the outer resistance elements, are designed in the form of a ring, and the disk-shaped contact elements, which are designed as support bodies, have a central recess; the center recesses of the disk-shaped contact elements are penetrated by a plastic clamping sleeve which carries clamping elements for clamping the stack together.
  • An advantage of the resistance device according to the invention is that the components required for clamping them together run within the stack forming the resistance device, so that no additional space is required in the radial direction due to the components required for clamping the stack.
  • Another advantage is seen in the fact that the central bracing of the resistance device according to the invention provides a high mechanical strength, which is additionally promoted by the fact that the disk-shaped contact elements are designed as support bodies, that is to say are designed to be relatively solid.
  • the resistance device according to the invention is to be used in combination with inductive voltage transformers for fully insulated, metal-encapsulated high-voltage switchgear.
  • Such switchgears are known to be spatially very narrow, so that corresponding requirements the facilities to be accommodated in them must also meet. This is the case with the resistance device according to the invention.
  • the adapter sleeve of the resistance device according to the invention is subjected to tension, it advantageously consists of a fiber-reinforced plastic.
  • the adapter sleeve can accordingly be made of a glass fiber material, but the use of a textile fiber-reinforced casting resin is preferred, because such a plastic has also proven to be advantageous in SF 6 -insulated switchgear.
  • the clamping sleeve of the resistance device according to the invention advantageously has bushings at its ends for attaching the clamping elements.
  • These bushings can be attached to the adapter sleeve in different ways; However, for reasons of strength and manufacturing, it is considered to be particularly advantageous if the bushings are glued onto the adapter sleeve.
  • the tensioning elements can also be designed differently in the resistance device according to the invention; However, an embodiment is preferred in which a tensioning element designed as a tensioning disk is fastened to the bush at one end of the tensioning sleeve and the bushing at the other end of the tensioning sleeve has a thread onto which a tensioning element designed as a pressure disk is screwed.
  • the inner resistance elements in the resistance device according to the invention are at the same height as dimension the outer resistance elements in cross section such that each inner resistance element has an electrical resistance of the same magnitude as each outer resistance element.
  • the inner and outer resistance elements are made of the same resistance material, then the inner resistance elements are advantageously dimensioned such that they have a volume that matches the outer resistance elements.
  • each disk-shaped contact element has a circumferential, outer ring, the diameter of which corresponds to the height of the disk-shaped contact element measured via the impressions.
  • the resistance device 1 contains a multiplicity of disk-shaped contact elements 2, which are successively embossed in the direction of an axis 3 of the resistance device 1.
  • Each disk-shaped contact element 2 has a central recess 4.
  • each disk-shaped contact element is provided with an indentation 5 open to one side for receiving an inner resistance element 6 with a relatively small diameter.
  • Another indentation 7, which is open towards the other side of the disk-shaped contact element 2 serves to receive an outer resistance element 8 with a larger diameter in comparison.
  • Each disk-shaped contact element 2 has a circumferential, outer ring 9.
  • the ring 9 is dimensioned such that its diameter D corresponds to the height H of the contact element 2, which can be measured via the impressions 5 and 7.
  • the ring is used to control the electrical field strength and prevents the locally permitted field strength from being exceeded.
  • Resistance device 1 on an inner resistance element 6 with a smaller diameter and an outer resistance element 8 with a larger diameter follows in the axial direction.
  • the galvanic connection between successive resistance elements 6 and 8 takes place via the disk-shaped contact elements 9, which do not differ in their design; because the disc-shaped contact element 9 located above the outer resistance element 8 can also be used in the same configuration as the disc-shaped contact element lying below this outer resistance element 8, in that it is only turned over.
  • the height of the inner resistance elements 6 and of the outer resistance elements 8 is identical; they only differ in their width in order to achieve that - with the same resistance material - that of one resistance element 6 or 8 given resistance value is the same size.
  • the disc-shaped contact elements 2 are penetrated in the region of their central opening 4 by an adapter sleeve 10 which consists of a resilient plastic, in particular a fiber-reinforced plastic.
  • the clamping sleeve is provided at one end 11 with a bush 12 which is glued onto the clamping sleeve 11.
  • a tensioning disk 13 is fastened to the bushing 12 and has an almost as large diameter as the disk-shaped contact elements 2. For reasons of insulation technology, the tension disc is bent on its outer circumference in the direction of the adjacent disc-shaped contact element 2. Between the clamping washer 13 and the adjacent disc-shaped contact element 2 are disc springs. 14 attached.
  • a contact piece 15 is attached to the outside of the clamping disk 13, which extends into the interior of the clamping sleeve 10 and serves to receive a contact pin, not shown in the figure.
  • the resistance device 1 is connected on this side via this contact pin.
  • a further bush 17 is glued onto the adapter sleeve, which has a thread . wearing.
  • a thrust washer 18 is screwed onto the bushing 17 and has an internal thread 19.
  • the pressure plate 18 is provided with a recess 20 on its side facing the inside of the resistance device 1 in order to fix the uppermost inner resistance element 6 in position and 8 together with the disk-shaped contact elements to form a mechanically very solid structure, the disk-shaped contact elements 2 contribute significantly to the mechanically stable design due to their relatively massive construction as structural elements.
  • a disk 21 prevents the uppermost inner resistance element 6 from being damaged.
  • the electrical connection of the resistance device 1 on its upper side in the figure takes place via the thrust washer 18, which has a central bore 22 for this purpose.
  • a contact bolt (not shown) can be passed through this center bore 22 and then establishes an electrical connection, for example with the inner conductor of a fully insulated, metal-encapsulated high-voltage switchgear.
