Definitions

  • the invention relates to a current conductor of an NH fuse device or NH fuse switchgear with two parallel ones Cut-offs, one section of which with a busbar and the other section with a contact of a pole is connectable, and with a right angle to them extending and connecting this middle part, the sections and the middle part are arranged approximately Z-shaped, and wherein the Current conductor can be connected to a current transformer and a housing with such a conductor.
  • a 455 589 is a base for one with a current transformer provided NH fuse device or NH fuse load switch device known of a generic conductor having.
  • the middle part of the conductor is shortened so far that within the housing between that of the busbar associated lower section of the conductor and the busbar sufficient space is created for the current transformer.
  • the lower section of the conductor is in this way with the busbar screwed that the screw through the toroid of the current transformer is guided and in this way forms the primary winding.
  • the invention is therefore based on the object of a current conductor to develop the genus mentioned at the beginning so that the Current transformers can be easily accommodated in the housing, on the other hand but the required mechanical strength and current resistance is guaranteed.
  • the current conductor is designed so that the middle part takes over the function of the primary conductor in the current transformer.
  • the section cannot be detached from the middle section to connect, e.g. to solder and if the current transformer is defective replace this together with the conductor.
  • the section is releasably connected to the central part, e.g. is screwed, since then only the current transformer in the event of a defect needs to be replaced, which is a slightly cheaper option represents.
  • the central part is cylindrical represents the best embodiment, with preference being given to the middle part is a solid cylinder. Deviations from the cylinder shape or Full cylinder shapes are possible without the scope of the present To leave invention, as far as constructive reasons in appears appropriate in individual cases.
  • the invention further relates to a housing with the features of claim 8.
  • the middle part has a length that is approximately the height H of the Housing or the recess in the housing corresponds in which Current conductor is included with the current transformer.
  • FIG. 1 shows a section a housing of an NH fuse device or NH fuse switch disconnector in an oblique view
  • Fig. 2 shows a section through the housing in the area of a current conductor
  • Fig. 3 with a a conductor connected to a busbar with a current transformer
  • Fig. 4 is a representation corresponding to Fig. 3, but without 5
  • Fig. 6 is a side view (cross-sectional view) to the current transformer of FIG. 5.
  • FIG. 1 shows a part of a housing 1 in an oblique view, in the area of a current conductor 2 or a busbar 3 a side wall has broken out.
  • the current conductor 2 the is arranged in a recess 4 in the housing 1, shows how this best seen in Figs. 3 to 6, an approximately Z-shaped Shape and in particular consists of an upper section 5, a lower section 6 arranged parallel thereto and one Middle part 7, the upper section 5 and the lower section 6 connects with each other.
  • the middle part 7 is a solid cylinder, which is the lower of its Section 6 facing end face has two threaded bores 8, those in the lower section 6 assigned two countersunk holes 9 are.
  • the lower section 6 can thus with the middle part 7 two screws 10 are screwed so tight that one also for high Flows suitable press connection between the middle part 7 and the lower section 6 is created.
  • the upper section 5 has an angled toward the central part 7 Leg 11, the end 12 in a slot 13 in the middle part 7th is recorded. For the firm connection of the leg 11 with the Middle part 7, these are soldered together at the edges 13.
  • the housing 1 has a height H and the middle part 7 and the leg 11, which is an extension of the Middle part 7 represents, together have a length that is about corresponds to the height H of the housing and in particular the recess 4.
  • Sections 5 and 6 have a cross-sectional shape as for Current conductor of NH fuse devices or NH fuse load switch devices are common. Because of the limited space in the recess 4 in the housing 1, however, if possible small current transformers 14 are used, as shown in FIGS. 1, 3, 5 and 6 are shown.
  • the bore diameter of the toroid of the current transformer 14 is therefore usually smaller than that Width of the current conductor 2, so that the middle part 7 a correspondingly smaller diameter than the width of the conductor must have. So that at a height of the middle part 7, the height of the current transformer 14 corresponds to that inserted into the middle part 7 End 12 of the leg 11 is not a disability, the Width of this end 12 is therefore not greater than the diameter of the Middle part 7. To work around this problem, of course the height of the middle part 7 also greater by that amount than the height of the current transformer 14, around which the end 12 in the middle part 7th is plugged in.
  • the upper section also corresponds to the prior art 5 of the current conductor 2 connected to a contact head 16, the one Contact knife e.g. of a fuse.
  • the other contact knife the fuse is received in a contact head 17, the 1, however, can be seen without the associated current conductor.
