  • the cable conductor is connected to the contact cap of the fuse cartridge by a contact element designed as an angular tab, the tab being screwed to the cable conductor.
  • connection parts in the subject of DE 32 44 424 A1 entails that the replacement of the HR fuse cartridge is complex. Also, due to the large lateral surface of the outer bushing, a certain stiffness when pulling off the angled connector cannot be avoided even if lubricant pastes are used. The bushing surfaces and also the insertion opening must be greased carefully.
  • an isolator-encapsulated electrical switchgear with built-in fuse cartridge is known, which is arranged with its ends and the metal fittings arranged therein, each within an isolating part designed as a fuse plug, which has a conical extension for a conically shaped opening that is formed transversely to the fuse cartridge of a device-side insulating material part. Plug contacts are arranged in the lugs and the insulating parts.
  • the fuse-side insulating material part can be provided with conductive lacquer on the inside.
  • the connecting device comprises a so-called saddle jacket, which can be connected to the cable connection piece and can be moved by a so-called shotgun rod, a device which can be connected to the device for receiving and releasably holding the saddle jacket in several positions next to the device with a lever device for actuating the saddle jacket, through which the cable connector is pressed onto the socket or pressed away from it.
  • DE 30 04 856 A1 discloses a gas-insulated medium-voltage switchgear assembly with an air-filled container containing a high-voltage fuse with plug connections for cable plugs.
  • the interior of the container and thus the fuse are accessible via an easily removable cover from the outside accessible, the container being surrounded, with the exception of the sealing cover, by a further metal-filled, insulated gas container having contact leads (bushings) into the container interior.
  • the cap of the inner container has a handle and serves as a handle for moving the fuse.
  • the bushing facing away from the transformer cable has a contact piece connected to an electrical device arranged in the interior of the network station and a conical opening surrounding the latter, and the fuse plug assigned to this opening has a conical extension for this opening which is formed transversely to a fuse enclosure, the extension being longer than this and is provided with an opening for receiving the contact piece which runs through to the fuse space of the fuse encapsulation.
  • a contact element leading to the fuse space is fixedly arranged in this continuous opening.
  • a holding bracket which can be pivoted via the securing plug is arranged on the feedthrough, through which the attachment is compressed in the conical opening and the opening can be fixed in an electrically sealing manner.
  • This configuration of the fuse connection device which can be removed from the bushing after the holding bracket has been swiveled up, enables an HH fuse cartridge to be inserted and replaced in a simple manner and with little effort.
  • the retaining bracket including the bushing and the securing plug, can be U-shaped and each have a compression spring in the area of the free ends of its legs, one of which has an abutment on the respective leg end and the other abutment on the fastening flange of the bushing which supports the bracket apply its web connecting the inn - and thus also the safety plug - towards the bushing, wherein the pressing force of the bracket can be predetermined by appropriate choice of the compression springs.
  • the abutments can advantageously be formed from a pressure surface and a guide pin formed thereon for abutment and locking, over which the respective end of the compression spring is placed in a simple manner.
  • the retaining bracket In the operating state, the retaining bracket can be locked by a latching element which is formed on the side of the fuse encapsulation facing away from the attachment.
  • a manual intervention can be arranged on the fuse connector side, which facilitates operation.
  • the fuse plug can be made of silicone rubber and can be formed in one piece with the attachment, which is advantageous in terms of technology and assembly technology.
