Definitions

  • the invention relates to a fuse connection device for encapsulated medium-voltage switchgear in accordance with the preamble of claim 1.
  • HV fuse high-voltage, high-performance fuse cartridge
  • two connecting parts are provided, in which the HH fuse cartridge is inserted.
  • the electrical connection of the HV HRC cartridge to the switchgear on the one hand and to a connection cable on the other hand is made by means of contact elements in the connection parts.
  • the design of the connection parts means that replacing the HV HRC cartridge is problematic and can also impair the required dielectric strength.
  • the invention is therefore based on the object of improving the fuse connection device of the type described above in such a way that the insertion and replacement of the HV fuse cartridge are simplified and the dielectric strength is increased.
  • connection parts make installation considerably easier when inserting and replacing the HV backup cartridge.
  • dispensing with external conductive coverings on the connection parts which are grounded at a suitable point, and by dispensing with corresponding conductive coverings inside the connection parts to avoid high field strengths, the production of the connection parts is considerably simplified.
  • the required dielectric strength is achieved by a seal between the connection parts and a plastic tube connecting the connection parts on the corresponding sealing surface.
  • a bushing 3 is used in the wall 2 of a switchgear 1.
  • the implementation has the task of supplying a cable conductor 4 from the interior of the switchgear to an HV HRC cartridge 7.
  • a connection part 5 serves as the connection part between the bushing and the fuse cartridge.
  • This connection part has a conical opening on the system side, which allows the connection part to be plugged onto the bushing, which has a corresponding outer cone in the connection area with the connection part.
  • the connector has an interior 12 which has three openings 13, 17 and 25 to the outside.
  • the opening 13 is designed conically on the inside in such a way that the outer cone 14 of the bushing 3 can be inserted into this opening.
  • the cable conductor 4 in the bushing is connected at the end inside the interior with a tab 20 which is supported on the inner edges of the connecting part and is then fixed with a screw connection.
  • the tab is used for the connection between the cable conductor and a contact cap 19 of the HV backup cartridge.
  • the second opening 17 serves to receive a removable one. Plug 18. Through this opening, the condition of the release pin 21 can be viewed, i.e. that is, it can easily be checked at any time whether the fuse has responded.
  • the third opening 25 is used to hold the HV backup cartridge.
  • the diameter of the opening 25 is much larger than the diameter of the HR fuse cartridge.
  • the contact between the contact tab and the contact cap is made by a contact spring 26 which is screwed to the contact tab.
  • the connector 10 and 11, not shown, is designed in the same way as the connector 5, so that a detailed description is omitted.
  • the connection between the connecting parts 5 and 10 or 11 is made by a plastic tube 27.
  • the voltage-tight sealing takes place between the connecting parts 5, 10 and 11 and the plastic pipe on a common sealing surface 28.
