Definitions

  • the invention is based on current contact arrangements a current switch according to the preamble of claim 1.
  • the invention takes to a prior art reference, as it is from DE 19524217 Al is known.
  • a gaseous insulation and Circuit breaker filled with extinguishing agent specified Nominal current is carried over a contact bridge.
  • the Contact bridge is rotatably supported and with a tension spring connected to the fixed contact arrangement.
  • the invention as defined in claim 1 solves the task of current contact arrangements of a current switch continue to develop in such a way that at Separation of the switch contact two interruptions and thus two Arcs occur.
  • An advantage of the invention is that when separating the Switch contacts overall a higher arc voltage that creates a faster commutation of the current guaranteed.
  • these double power cuts by simple Guide elements can be achieved on either of the two Current contact arrangements are arranged.
  • Fig. 1 shows a section of a sectional view circular cylindrical nominal current contact arrangement of a Circuit breaker or current switch in the closed state, wherein with (1) whose longitudinal axis is designated.
  • a movable 1st Current contact arrangement (K1) and a fixed 2nd Current contact arrangement (K2) are by a contact finger or bridged by a contact bridge (3).
  • This Contact bridge (3) is between a 1st end Switch contact (P1), which is in the closed state of the current switch is in pressure connection with the first current contact arrangement (K1), and a 2nd end switch contact (P2), which in Closed state of the power switch with the 2nd Current contact arrangement (K2) is in pressure connection, in a Bulge or a bridge guide element (A) cam-shaped educated.
  • the contact pressure is set by means of a compression spring (4), which, on the one hand, in a recess in the second
  • At the 1st current contact arrangement (K1) is an electrical insulating current contact element (2) with a end contact surface (2A) rigidly attached, for. B. means a screw connection.
  • This contact surface (2A) corresponds with the bridge guide element (A); it is in the closed state of the current switch slightly from the bridge guide element (A) spaced.
  • Fig. 2 shows the current contact arrangements of the current switch 1 in its open state.
  • the closed state is the 1st current contact arrangement (K1) in the direction an arrow (5) shifted to the right and thus also that Current contact guide element (2), which with its Contact surface (2A) against the bridge guide element (A) against the pressure effect of the compression spring (4) after the contact bridge (3) presses above, the contact bridge (3) with a Bridge stop (Al) on a counter stop of the 2nd Current contact arrangement (K2) is present.
  • the first switch contact (P1) from the 1st current contact arrangement (K1) without the Contact surface (2A) of the current contact guide element (2) on the Bridge guide element (A) rests so that there is a 1st Arc (B1) arises.
  • the contact surface comes shortly afterwards (2A) to abut the bridge guide element (A) and press the Contact bridge (3) against the action of the compression spring (4) above until the bridge stop (Al) comes to a stop.
  • the 2nd switch contact (P2) moves away from the 2nd Current contact arrangement (K2), so that there is a second arc (B2) arises, which is electrically in series with the 1st arc (B1) is switched and thus the arc voltage doubles.
  • FIG. 3 and 5 show a schematic diagram and a Design variant of current contact arrangements one Current switch in the closed state, where a contact bridge (3 '), in contrast to the contact bridge (3) according to FIG. 1, as Bridge guide element has a cylindrical pin (8), around its axis the contact bridge (3 ') can be rotated.
  • This Pin (8) is in an elongated hole or guide slot (7) a lower stop (9) in one on the 2nd Current contact arrangement (K2) attached slide guide (6) slidable.
  • the compression spring (4) engages to the right of the pivot point of the Pin (8).
  • the force of the Compression spring (4) onto the entire contact bridge (3 ') in such a way that the first and second switch contacts (P1, P2) are connected to the first and 2.
  • Current contact arrangements (K1, K2) are pressed.
  • the cone (8) is not in contact with the stop (9).
