Definitions

  • the invention relates to a cover according to the preamble of Claim 1, as in particular in the case of transformers Power supply networks are used.
  • FR 2 335 970 shows a device for securing and sealing isolating of stripped electrical conductors connected with a screw terminal Clamping screws are connected to each other.
  • a hinged cap allows access to at least one of the clamping screws by means of a Screwdriver.
  • EP 0 050 244 shows a removable cover for terminal strips from Electrical devices, in particular transformers, with a cover housing, locking it on the plastic base made of plastic at least two mutually independent fastening means, wherein the use of a tool to solve at least one of these means is required, characterized in that at least this one, exclusively using a tool releasable fasteners as Snap lock is formed.
  • the removable cap enables the ones hidden under the cover Divide through an opening concealed by the cap without a large one Effort can be grounded.
  • the grounding is simplified in that a clearly on the connecting bolt projecting from the terminal grounding bolt is arranged. This Grounding stud protrudes at least partially beyond the cover and becomes covered by the cap in normal condition. If the cap is removed the grounding bolt is easily accessible, which means that a Earthing device is significantly simplified.
  • the cap is pivotable on the cover is attached. This is preferably done by means of a hinge. As a result of that the cap is connected to the cover, it can be grounded do not get lost.
  • a clip-on cap on the other hand, has the advantage that it is optimally accessible of the grounding bolt.
  • One provides optimal security against unauthorized opening of the cap Attachment where a key or tool is used to open the cap is required. In this way, accidental opening by unauthorized persons safely avoided.
  • the earthing device (or an earthing connection the same) are put on the cap in normal operation, where they always is ready for use.
  • the grounding device can be made by the similar design of the end regions can be used as such an opening tool.
  • a spherical one Design enables optimal electrical contact between the grounding bolt and the grounding device. But it is also, for example a design of these end areas as a ring or T-piece possible.
  • the cover can be made in one piece by a production in Immersion process.
  • the cover can also be made of two by injection molding manufactured half shells exist. This type of production is essential cheaper.
  • a labyrinth seal at the seams between the two half-shells the cover provides a particularly secure way of sealing towards the environment.
  • a particularly simple assembly of the cover hood enables a snap connection of the two half shells.
  • a screw connection can be provided to remove the cover his.
  • Fig. 1 shows a cover 1, one of a bushing insulator 3rd of a transformer in an energy supply network outstanding and in Operation Live connecting bolts 5 covers touch-proof. Through the cover 1, a terminal 7 is also connected to the Connection bolt 5 connected and the conductor 9 to an electrical Device leads, covered.
  • the cover 1 is of almost a mirror image.
  • Two each other corresponding flange areas 13 and 14 between the passage for the Bushing insulator 3 and the passage for the conductor 9 are by means of a Screw connection 19 interconnected to secure the cover 1 against unauthorized weight loss.
  • Both the screw and the nut of the Screw connection 19 are made of plastic. It is also on the cover 1 a cap 17 is provided.
  • the connecting bolt 5 is extended upwards and forms an earth bolt 21, which protrudes into the cap 17.
  • the cap 17 is pivotable on the two Half-shells 13 and 14 attached so that an earthing over the earthing bolt 21 is possible (see FIG. 2).
  • both the grounding bolt 21 and the cap 17 have a spherical end region 23 or 25 on which the ground connection 27 can be attached.
  • cover 1 or the cap 17 can also small holes from For example, 4 mm diameter can be provided through which a voltage tester can be introduced to check whether a voltage on the Grounding bolt 21 is present. If there is no voltage, it can be grounded and then work on the device.
  • the second embodiment in Fig. 3 shows a cover, which in essentially from two half-shells 113 and 114 of almost mirror images Shape exists, which are made of injection molded parts.
  • a snap connection 115 connects the two half-shells 113 and 114 to one another.
  • a Labyrinth seal 116 seals the abutting edges.
  • the second exemplary embodiment agrees in particular with regard to the cap the first embodiment.
