Definitions

  • the invention has for its object to build a mechanical AND gate to simplify and reliable Ensure working methods.
  • the AND gate according to the invention has the property that only a full stroke of the cables for the input signals operated the cable for the output signal. There is only one of the input signals, the cable remains for the output signal in peace.
  • the AND gate With sufficient dimensions of the AND gate, the relative change in the distance between the cables when swiveling of the coupling carriage so low that of special means can be dispensed with to compensate for the misalignment.
  • the AND gate is intended to be used for Circuit breakers with compact dimensions also small and compact, it is recommended that the Coupling slides extending in its longitudinal direction Elongated holes for receiving a slide for each passage who has cables assigned to the input signals. At this arrangement, the coupling slide depends on remaining third, assigned to the output signal Pull out.
  • FIG. 1 shows a basic circuit diagram with three circuit breakers.
  • Figures 2 and 3 show an AND gate schematically in the Top view and in a side view.
  • FIG. 4 shows the AND gate according to FIGS. 2 and 3 when one of the input signals is present, while FIG. 5 represents the state when the other input signal is present.
  • FIG. 1 is a schematic diagram with three Circuit breakers LS1, LS2 and LS3 shown.
  • the Circuit breakers LS1 and LS2 each of a power supply assigned via a transformer while the circuit breaker LS3 is assigned to an emergency power generator G.
  • G an emergency power generator
  • a mechanical AND gate U using which the mutual locking task described above the circuit breaker LS1, LS2 and LS3 to solve the following figures show.
  • the AND gate U has a sheet metal, for example Carrier T on the top and bottom of the Formation of an edge web T1 is folded twice. Openings T2 are used for any attachment of the AND gate U in a switchgear or on a circuit breaker.
  • the edges of the beam T serve as an abutment of three flexible transmission elements S1, S2 and S3, the each a jacket S4, S5 or S6 and one in the jacket S4, S5, S6 have guided cable S7, S8 and S9.
  • the wire rope hoists S7, S8 and S9 are with a beam-like Coupling carriage K connected, the two parallel Sheet metal parts K6 is formed, as is closer to FIG can be seen. Both sheet metal parts K6 are riveted Spacers K7 connected.
  • the wire rope hoists 57, S8 and S9 push through a cylindrical slide K1, K2 or K3, that in opposite openings of the coupling carriage K intervenes.
  • the openings for the sliders are K1 and K2 as elongated holes K4 and K5. Of the Coupling carriage K is thus through the connection with the Cables S7, S8 and S9 floating on the support T.
  • FIGS. 2 and 3 show the catches S12 and S13 on the sliders K2 and K3 while the driver S11 is at a distance D from the slider K1.
  • the arrangement of the Transmission elements S1, S2 and S3 relative to the coupling carriage K important.
  • the S9 wire rope hoist Transmission device S3 for the output signal A is parallel arranged to the cable pull S7 and engages on the opposite End of the coupling carriage K.
  • the S8 cable pull Transmission device S2 for the input signal E2 intervenes approximately in the middle of the coupling carriage K and acts in the opposite direction as the cables S7 and S9.
  • the transmission elements S1 and S2 are each an input signal E1 or E2 assigned, while the transmission element S3 to Forwarding an output signal A is used.
  • the Coupling slide K in its rest position, in which it is on a dot-dash basic position labeled "0" is aligned.
  • the designations of the input signals E1 and E2 and the output signal A are placed in brackets, to indicate that these signals are not active.
  • FIG. 4 shows the state that an input signal El acts on the cable pull S7.
  • the driver S is the Slider K1 no longer in the distance D, but in compared to a shorter distance D1.
  • the coupling slide K thus remains unactuated, so that no output signal A is delivered.
  • both input signals E1 and E2 occur like this 6 shows, the coupling carriage K is taken along and from the reference level “0" to the one below Reference plane “1" moved parallel to itself.
  • the cable pull S9 is actuated, which emits the output signal A corresponds.
  • This is used in a known manner the circuit breaker LS3 (Fig. 1) against engagement block if by closing the circuit breaker LS1 and LS2 the input signals E1 and E2 are output.
