Definitions

  • the invention is in the field of electrical switches and relates to a fuse switch disconnector with a housing, a pivotally mounted on a pivot bearing on the housing cover and at least one fuse link, wherein the contacts are closed with the lid closed and the mating contacts associated with them and in which with the lid open, the contacts are open.
  • Such a generic fuse circuit breaker is for example from the document DE 196 15 859 A1 known.
  • the fuses When opening (swiveling) the lid, the fuses are swiveled with the lid.
  • the trained as a contact blade contacts the fuse links get out of engagement with the formed as a contact springs mating contacts.
  • the quality of the shutdown behavior - ie the opening process of the contacts and thus also the quenching behavior - is dependent on the speed with which the lid is opened. The separation of the contacts is thus operator-dependent.
  • a locking slide for a fuse with a manually operated switch with on and off state is known, the fuse switch is removable including the fuse link.
  • a web is provided, via which the switch is locked in the on state by means of a cam.
  • a movable switching contact is pressed by a switch spring to opposite switch tongues.
  • this switching contact is manually brought from on to off state by means of a switch knob.
  • the fuse holder is released from the locking web and the switching contact is pushed back by a switching rod against the switching spring, being held by the switch tongues at a distance.
  • a multi-pole fused switch arrangement which has a common housing with subspaces for the elements of the individual switch fuse units.
  • document FR-A-2 818 005 discloses a fuse switch disconnector according to the preamble of claim 1.
  • the invention is therefore based on the object of making the fuse switch disconnector with respect to the protection of persons and equipment safer.
  • the fuse switch disconnector 1 has a housing 2 and a cover 3.
  • the lid 3 is a Swivel bearing 4, which is arranged stationary to the housing, pivotally.
  • the housing and the cover have in known manner, not shown in the figures partitions to form Polhuntn.
  • a carrier 5 is pivotally held, which carries a fuse 6.
  • the pivot bearing 4 of the lid 3 at the same time forms the pivot bearing of the carrier 5.
  • the carrier 5 is in an ON-position, formed as a contact blade contacts 7 of the fuse links 6 are in electrical contact with mating contacts 8.
  • the mating contacts 8 may be formed, for example, as Lyra prestigee.
  • the fuse breaker switch has a latching device 9 which couples the carrier to the lid such that, with the lid closed, the carrier is held under the force of a first spring 10 in an ON position - in which the contacts 7, 8 are engaged - and at a given opening angle ⁇ of the lid, the carrier for transfer to an OFF position - in which the contacts 7, 8 are open (see. FIG. 4 ) - is released.
  • the Verklinkungs worn 9 may be formed by a stop surface 11 of the carrier 5 and a stop surface 11 associated stop 12 in the form of a rotatable half-wave.
  • the half-wave is pivoted under the force of a second spring 13 in the movement path 14 of the carrier 5, which in turn is supported under the force of the first spring 10 on the half-wave, and thus latched in its ON position.
  • the carrier 5 initially remains in its ON position during the opening process of the lid 3, so that the contacts 7, 8 remain closed. Only with reaching the predetermined opening angle ⁇ of the lid 3 succeeded on the cover 3 trained driver 15 in abutment against an arm 16 of the half-wave and pivots it out of the movement path 14 of the carrier 5.
  • the carrier for transferring in the in the FIG. 4 release the OFF position shown. In this OFF position the carrier is pivoted under the force of the first spring 10, wherein the contacts 7 of the fuse links 6 are pressed from the associated mating contacts 8 and thus electrically separated from each other.
  • an optimal opening speed which is determined by the mass of the backup insert 6 provided with the carrier 5 and the extinguishing time to be achieved, selectively selectable by selecting a spring with the appropriate spring force.
  • Verklinkungs worn 9 is not on in the FIGS. 2 to 4 illustrated embodiment limited. Rather, any other functionally equivalent latching device can be provided.
  • a rebound lock may optionally be provided.
  • a means 17 for positive entrainment of each of the carrier 5 is provided with the lid 3.
  • This inevitable entrainment of each of the carrier with the lid acts on exceeding the predetermined opening angle ⁇ of the lid by a predetermined value .DELTA..alpha.
  • the inevitable entrainment takes place so shortly after the release (unlatching) of Carrier for transferring into its OFF position, wherein the value .DELTA..alpha. Of exceeding the predetermined opening angle .alpha. Is selected so that the positive entrainment can only take effect in the case of welded contacts. In non-welded contacts, however, the transfer of the carrier 5 takes place in its OFF position according to the invention under the force of the springs 10. In this case, the inevitable entrainment is no longer effective.
  • FIGS. 1 to 4 are as a means 17 for positively entraining the carrier 5 with the lid 3 for a one-armed, hinged to the support and at the end of their free lever arm each provided with a pin 18 lever 19 and the other in the lid 3 formed, slot-like, the pins 18 associated guide contours 20 provided.
  • the ends 21, 22 of each of the guide contours 20 each end stops for the associated pin 18.
  • the position of the carrier 5 facing first 21 of the end stops is the value ⁇ + ⁇ the opening angle of the lid 3, in which the inevitable entrainment takes place, specified. Due to the position of the second 22 of the end stops, the OFF position of the carrier 5 in the lid 3 can be determined.
