Definitions

  • the invention relates to a fuse connection device for encapsulated medium-voltage switchgear according to the preamble of claim 1.
  • EP-A-0 110 008 which belongs to the state of the art according to Art 54 (3) EPC, a fuse is used in the fuse connection device, which causes an electrical disconnection. When triggered, the striker pin of the fuse has no function. It can It may be useful to have an alternative to triggering by electrical means.
  • the invention is therefore based on the object of strengthening the fuse connection device to such an extent that mechanical triggering is also possible.
  • FIG. 1 An embodiment of the invention is shown in a drawing and is explained in more detail below:
  • the figure shows a fuse connection device with mechanical triggering in side view, in section.
  • 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 connecting part 5 is used, which has an interior 12 with three openings 13, 15 and 17 to the outside.
  • the opening 13 is designed conically on the inside such that an 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 within the interior with a tab 20 which is supported on the inner edges of the connection part and is then fixed with a screw connection.
  • the tab serves the connection between the cable conductor and a contact cap 19 of the fuse cartridge.
  • the second opening 15 is used to receive the fuse cartridge, which is inserted so far into the connecting part that the contact cap is located inside the interior.
  • the live parts of the fuse cartridge are now completely encapsulated.
  • the connecting part is made of a rubber-elastic material and includes the porcelain body 16 of the fuse cartridge, so that a good seal is achieved at this point.
  • the third opening 17 serves to receive a removable plug 18. Through this opening, the condition of the striking pin 21 (release pin) of the HH safety cartridge can be viewed.
  • a bolt 25 is arranged within the connecting part.
  • the wall section of the connecting part 5 closest to the bolt head is designed as a force transmission zone 26.
  • circular grooves 27 and 28 are provided on the inside and outside, which together with the elasticity of the material of the connecting part 5 ensure sufficient bulging at this point.
  • a lever 29 is attached, one end of which is placed on the power transmission zone 26 and the other end of which is operatively connected to the mechanical drive of a switching device.
  • the bolt 25 is inserted in a holder 30 which is equipped with two arms 31 and 32 lying one above the other.
