Definitions

  • the invention relates to a busbar connector according to the preamble of claim 1.
  • Busbars are bare metal in the contact area of the shell terminal and covered with an insulating layer outside it.
  • the busbar connection point is enclosed by an insulating body which is pushed onto the outer cone of the bushing on the housing side, an opening for mounting the busbar sections on the side of the busbars remote from the housing and sleeve-shaped openings for the ends of the outer busbars which are aligned parallel to the wall of the housing having.
  • the opening for mounting the busbars can be closed by a sealing plug which has a casting nut which can be screwed onto the threaded bolt.
  • This busbar connector is designed for busbar systems for a maximum current of 1250 A, which results in a diameter of 32 mm for the busbars made of solid copper material. With larger nominal currents, larger dimensions are required, also because the heat losses increase with them. Larger busbar diameters in turn require larger busbar connectors that can only be connected to the existing busbar system with special Aladaptern are connectable.
  • DE 295 01 824 U1 shows a 'double-decker' busbar connector which comprises a fixed molded insulating part which, although it allows multiple accesses for coupling busbars, is otherwise unchangeable.
  • the invention has for its object to provide a busbar connector for metal-encapsulated individual fields of switchgear for large rated currents, which can be integrated in known busbar systems, but allows a variation in the access possibility for busbars.
  • the task will connect to busbars! according to the preamble of claim 1 solved by its characterizing features.
  • the busbar connector should preferably also be usable on SF6-insulated switchgear.
  • the essence of the invention lies in the fact that outer busbars on a busbar connector for metal-encapsulated individual modules of electrical switchgear assemblies, which can be arranged in a row, are arranged on several levels and are perpendicular to the axis of the bushing.
  • the bushings are assigned to each phase of the switchgear.
  • An additional busbar can be mounted on a further end adapter via the coupling adapter.
  • the insulating bodies of the coupling adapter and end adapter are plugged into one another.
  • a conical insertion area is formed inside the insulating body of the end adapter.
  • Inside the insulating body of the end adapter there is a cylindrical cavity with a A metal support tube This cavity is a Faraday cage and receives the power supply pin.
  • the conical plug area of both adapters closes off the double-decker busbar connector in a voltage-tight manner.
  • the outer conductive layers of both insulators meet at the edge of the plug-in area.
  • the second busbar is exactly like the first busbar in the Coupling adapter installed
  • the contact half-shells in the end adapter are firmly attached to the power guide bolt.
  • the second busbar is also enclosed by contact half-shells and screwed using threaded bolts, spring washers and nuts.
  • the end adapter can be closed with a screw insert and connected with a conductive cover cap as a capacitive measuring point.
  • the cover cap is conductive with the leading layer of the
  • Both adapters consist of flexible insulating material, preferably made of silicone rubber. Except for the conical insertion area (that is, the conical opening and the outer cone), a conductive layer is applied to the outside of the adapters. The conical insertion area is designed to conform to the contour of the opening so that the interfaces close the adjoining adapter under tension.
  • the support tube is inserted into an undersized cylinder without cavities in the insulating body of the end adapter.It can also be inserted in the tool for the insulating body for rinsing, so that there is a firm connection. The support tube is in contact with the inner control sleeve of the Insulator of the end adapter
  • busbar connector can also be formed without guide layers on the adapters

  • the closure or adapter opening of the end adapter lies in the axial extension of the bushing.
  • the insulating body and the insulated shaft of the closure pieces have a conductive coating.
  • Opening can be closed by a screw insert and covered with a cap made of a conductive material.
  • the inside of the insulating body has field control sleeves in the areas bordering the shell clamps and in the entry areas of the openings for the ends of the outer busbars. Unoccupied clamping points on the shell clamps can be closed with locking pieces.
  • Closure piece for an unoccupied opening can be formed from a Cu bolt, which has a clamping piece on the shell clamp side, which corresponds to the end of a busbar.
  • the arrangement of an end adapter on the power guide bolt of the first coupling adapter which can be separated but can also be expanded to include multiple storeys, has the advantage that the nominal currents can be divided into two or even more busbars.
  • the multi-level busbar connector according to the invention can therefore be used in an advantageous manner without converting or changing a basic element of a single-level busbar connector.
  • the connector can be integrated into given busbar systems and can be used as a transition connector
  • Busbar systems can be used.
  • the heating losses remain unchanged due to the unchanged diameter of the busbars and are therefore manageable as before.
  • Connector can even be used as a multiple cross connector. Insertion openings and Predetermined clamping points can also remain unoccupied if they are closed with locking pieces.
