Definitions

  • This invention relates to a cabling system serving particularly for several three-phase circuits system the cut out fuses, hingedly connected to the base plate like switch levers, belonging to ranged symmetrically so that the axes of the unlike phases lie at the corners of a triangle.
  • Fig. 1 shows in front elevation a cable distribution board for two three-phase circuits, the cutout fuses of one circuit being shown switched in and those of the other circuit omitted.
  • Fig. 2 is a side elevation of Fig. 1. one cut-out fuse being in closed and the other two in open 5 position.
  • Fig. 3 is an end view of Fig. 1.
  • Fig. 4 shows the contacts 01' the signalling device.
  • Fig. 5 shows in elevation.
  • Fig. 6 shows the switch bar in elevation.
  • Fig. 7 shows in front view a modified construction of the cable distribution board.
  • Fig. 8 is a side elevation oi Fig. 7. 15
  • Fig. 9 is an end view of Fig. 7.
  • Fig. 10 shows in longitudinal section one of the releasable spring bolts.
  • Every two companion knife blade contacts of a phase are bridged both on the supply side and 40 on the delivery side by a cut-out fuse c adapted to be disconnected, oscillatably hinged on a and cutting out the cut-out
  • the switching may be either effected directly by hand or through the intermediary of a switch bar m, prothe fuse is intact,
  • the bar m enables the cut-out fuses c to be switched out and in individually or in common in that either the upper or the lower hooks o are hooked over the cross bars of the handle I.
  • An arrangement is further combined with the distribution board, which indicates the fusing of a cut-out fuse directly in the works or at some other observation place.
  • a bar p of insulating material is employed, which is provided with two contact barsv u, 'm'connected to a battery circuit, in which an optical or acoustic signal is connected up.
  • Each cut-out fuse has two lateral insulated contact springsw,':z: of different lengths, which, when the-fuse is switched in, bear on the bars u, v and can be bridged by a contact 11.
  • the contact 1 is carried by an insulated rod 2, extending into a bore 23 in the fuse c and encircled by a pressure spring 24.
  • oscillatable levers q are mounted on the brackets d, their free ends being interconnected by a common switch bar 21, carrying a handle 28.
  • Each lever q extends along the upper side of the fuses c between thelugs i and has a hole 28 at this point.
  • a sleeve 30 having a small bore at its outer end is tightly screwed into one of the lugs i, a bolt 32 encircled by a pressure spring 3! being inserted in this sleeve 30.
  • the bolt 32 has a small pin 33 and a knob 34.
  • the bore in the end of the sleeve 30 is provided with a small recess 35, through which the pin 33 can pass.
  • the bolt 32 assumes such aposition that it passes through both lugs i of the fuse c.
  • the distribution board can be operated and employed in a similar manner to a three-pole switch by actuating the handle 28 that is, the three-phase current net connected thereto can be switched in and cut out by one handle. Moreover, if one of the fuses has fused, the phase affected can be cut out separately, leaving the remaining phases in service.
  • the bolts 320! the contact fuses are pulled back by means of the knobs 34 until their pins 33 are situated outside of their respective sleeves 30 and then slightly turned so that they remain in the position illustrated in Fig. 10. Thus, by pulling back the handle 28, only the fused fuse is cut out,
  • a distribution board with fuses arranged one above the other and adapted to be cut out by hand comprising in combination a base plate, fuse carriers hingedly connected to said base plate, a switch bar, spring boltsdetachably and fixably connecting said carriers to said bar to allow said carriers to be selectivelyswitched inand out individually and jointly by said bar.
