Definitions

  • the invention relates to a quick-release and particularly reliable latch and a trigger mechanism and a quick-action earth electrode or a quick-action switch, in particular on or off switches and circuit breakers, or short-circuiters, in particular for low, medium and/or high voltage applications.
  • the switching times i.e. the speed that a switch, in particular a high-speed earthing device or short-circuiting device, requires in order to carry out a switching action after a switching signal are also closely related to the triggering mechanism.
  • Fast release mechanisms are known in the prior art, which like that EP2624272A1 based on chemical propellants. These have the disadvantage that it is not possible to use the switch again without great effort. Latches by means of ball detents, half-shafts and detent cages are also known, but these are particularly disadvantageous in terms of reliability.
  • the object of the invention is now to provide a latch, tripping mechanism and high-speed earthing or short-circuiting device that trips quickly, reliably and can be upgraded with simple means so that it is ready for a new switching operation after a previous switching operation.
  • the blocking element thus prevents movement of the drive rod in a first end position of the latch. If the blocking element is moved out of its blocking position by means of a second force, for example by a magnetic actuator, the blocking effect of the blocking element is thereby eliminated and the drive rod can move in a predetermined direction driven by the first force.
  • the first force is preferably generated by a spring or a set of springs, in particular by disk springs or a set of disk springs.
  • the duplicated components are arranged symmetrically about one end of the drive rod. This causes an additional stabilization of the latch.
  • the blocking element and the blocking element counterpart are movably, in particular rotatably, connected to one another at a connection point, with the blocking element counterpart being rotatably connected to the second transmission element or the first transmission element, so that the blocking element and the blocking element counterpart are in the first end position in are in an extended position, in which a movement of the latch into the second end position is prevented and so that the blocking element and the blocking element counterpart are in a kinked position in the second end position, so that the connection point has moved (in the direction of the drive rod) compared to the first end position.
  • the second force is particularly preferred for the second force to be applied at the connection point at which the blocking element and the blocking element counterpart are movably connected to one another.
  • the locking element and the locking element counterpart are movably connected by a pivot at the connection point, the locking element counterpart is rotatably connected to the second transmission element or the first transmission element with an axis or a bearing, the connection point being approximately centrally between the bearing and the locking element axis is arranged.
  • the second force is applied at the connection point at which the blocking element and the blocking element counterpart are movably connected to one another.
  • the blocking element is mounted in the first end position on the blocking element counterpart in such a way that the blocking element prevents movement of the catch out of the first end position.
  • Bearing is to be understood here in particular as meaning that the reduced first force presses the blocking element against the blocking element counterpart, ie the blocking element is supported against the blocking element counterpart, and movement of the drive rod is thus prevented.
  • the locking element counterpart is designed as a roller.
  • the effect of this is that the blocking element is on the one hand stably supported on the blocking element counterpart and on the other hand rolls over the blocking element counterpart with little loss.
  • an end of the locking element that is supported on the locking element counterpart has a flat, i.e. straight, or round shape with a first radius and the locking element is supported stably, in particular more stably, on the locking element counterpart that, with the round shape, the center point of the first radius does not go through the center point of the axis of rotation of the blocking element, i.e.
  • the center point of the first radius does not lie on a straight line which goes through the center point of the axis of rotation of the blocking element and the center point of the bearing of the counterpart blocking element, but on this line in the first end position in the direction of the Drive rod is offset away from the side, so there is an offset, in particular by 0.3 to 1.2 mm or 0.4 to 1.0 mm.
  • the first radius is preferably larger than a second radius of the locking element counterpart, in particular in the form of the locking element counterpart as a roller.
  • the bearing is a needle bearing.
  • a needle bearing has a particularly low rolling resistance and still has a preferred long-term stability.
  • a locking element return device is provided on the locking element in such a way that when the catch is transferred from the second end position to the first end position, the locking element return device causes the locking element to be returned between the first transmission element and the second transmission element, so that a Movement of the transmission element pair is prevented and the locking element rests against the locking element counterpart.
  • the blocking element has a notch in a region on the side facing away from the drive rod in the first end position, which is part of the outer contour corresponds to the blocking element counterpart, or simulates it.
  • a further exemplary embodiment relates to a tripping mechanism for a fast switch with a latch according to one or more of the above statements, the blocking element being movable by a magnetic plunger of a magnetic drive or another tripping unit from the first end position preventing the movement of the transmission element pair.
  • the blocking element rests on or against a blocking element stop in the first end position.
  • the blocking element stop is arranged in particular in such a way that it prevents a movement of the blocking element in the direction of the magnetic plunger or the other triggering unit beyond the first end position that prevents the movement of the pair of transmission elements and thus forms a defined starting position of the blocking element in the first end position that blocks the movement of the pair of transmission elements.
  • the blocking element stop is arranged on the magnetic drive or on one or more housing parts.
  • the arrangement of the blocking element stop on one or more housing parts is particularly advantageous, as this provides a better defined state for the latching in the first End position is created, which also simplifies the assembly of the Verklingung to a trigger mechanism.
  • first transmission element can be or is mounted rotatably on a first housing part via a first fastening axis and the second transmission element can be or is mounted rotatably on a second housing part via a second fastening axis, and the first housing part and the second housing part immovably in one Housing of the trigger mechanism are attached or form the housing.
  • the housing is designed in one piece or in multiple pieces.
  • Another embodiment relates to a high-speed or short-circuiter with a triggering mechanism according to one or more of the above statements, the triggering mechanism and together with the switch being arranged in a housing and the triggering mechanism moving from the first end position to the second after switching End position can be reversibly reset to the first end position.
