Definitions

  • the invention relates to a fuse connection device for encapsulated medium-voltage switchgear assemblies according to the preamble of claim 1.
  • a fuse connection device for encapsulated medium-voltage switchgear assemblies according to the preamble of claim 1.
  • Such a device is known from US-A-3,513,425.
  • This US-A-3 513 425 relates to a modular connection system for underground power distribution.
  • a switchgear is considered short-circuit proof if both its thermal and dynamic strength as well as the breaking capacity of the circuit breakers and fuses meet the maximum stress.
  • There are two ways to do this either adapt the system to the full short-circuit power of the network or limit the short-circuit power by suitable means in the system. For economic reasons, the latter route is preferred.
  • One of these means is the high-voltage high-performance fuse cartridge (HH fuse), which interrupts the short-circuit current before it has reached its maximum. The short-circuit current thus only affects the downstream system parts.
  • the inclusion of the vacuum fuse in the plug connection requires a relatively complex construction, especially when all the requirements have to be met. Apart from that, the previously known disadvantages of vacuum securing cannot be overlooked. This can lead to overvoltages in particularly critical cases. In addition, the vacuum fuse is not able to switch off small residual currents. It does not have a current-limiting effect.
  • the invention is therefore based on the object of providing a fuse connection device for encapsulated medium-voltage switchgear which allows an HV HRC cartridge to be incorporated into the system with simple and few means in such a way that the fuse cartridge can be easily replaced.
  • HV HRC fuse cartridge with only two connecting parts can be used between a gas-insulated switchgear and a cable end.
  • connection technology With the aid of the connection technology according to the invention, it is possible to use the HV fuse cartridges used in conventional switchgear assemblies even in gas-insulated switchgear assemblies while maintaining previous safety requirements.
  • the removable plug advantageously allows the trigger pin of the fuse cartridge to be observed to determine whether the fuse has blown.
  • 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.
  • An angle connector 5 serves as the connection part between the bushing and the fuse cartridge.
  • This angle connector has a conical opening on the system side, which allows the angle connector to be plugged onto the bushing tet, which has a corresponding outer cone in the connection area with the angle connector.
  • the securing side of the angle connector has a recess 6 into which one end of the securing cartridge is inserted. The other end of the fuse cartridge is inserted into a recess 8 in a straight connector 10.
  • the two recesses 6 and 8 are designed so that the contact caps 19 of the fuse cartridge are completely enclosed by the connecting pieces. Only the porcelain body 16 of the fuse cartridge can thus be seen between the two connecting pieces.
  • the straight connector has a recess for a cable end 9 on the side opposite the securing side.
  • Fig. 3 shows a special embodiment of the angle connector 5.
  • This has an interior 12, which has three openings 13, 15 and 17 to the outside.
  • the opening 13 is designed in the shape of an inner cone such 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 angle connector and is then fixed with a screw connection.
  • the tab serves the connection between the cable conductor and the contact cap 19 of the fuse cartridge.
  • the second opening 15 is used to receive the fuse cartridge, which is inserted into the angle connector so far that the contact cap is located inside the interior.
  • the live parts of the fuse cartridge are now completely encapsulated.
  • the angle connector is made of a rubber-elastic material and encloses the porcelain body 16 of the fuse cartridge so as to suck, so that a good seal is achieved at this point.
  • the third opening 17 serves to receive a removable plug 18. The state of the release pin 21 can be viewed through this opening, i. H. it can easily be checked here at any time whether the fuse has responded.
  • the angle connector 5 is coated on the outside with a conductive coating 23.
  • This covering is grounded at a suitable point.
  • the interior is provided with a corresponding conductive covering 24 which is live.
  • a metal tube 22 is provided which connects the connecting pieces receiving the fuse cartridge 7 to one another. This metal tube is arranged at a distance around the fuse, the ends of the metal tube contacting the conductive outer coverings 23, so that the entire structure is continuously grounded.
