Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • an electrical switching device such as a circuit breaker, a motor protection switch or a circuit breaker turns off the power
  • this may be due to tripping due to overcurrent or due to a short circuit current.
  • it is necessary to know the reason of the trip, so that any repairs can be initiated.
  • an electrical switching device is accompanied by a short-circuit indicator or short-circuit detector in the form of an auxiliary switch, as is known, for example, from EP 0 367 102 A2.
  • a pin projects out of the auxiliary switch, which is in communication with a component which is coupled to the electromagnetic release of the motor protection switch, so that the auxiliary switch is actuated via this pin, whereby a display for short-circuit release is given.
  • the object of the invention is to provide a device for indicating the triggering by a short circuit, which is improved over the known arrangement.
  • the retainer is a lever rotatably mounted at one end against which a step rests against the contact carrier in the rest position and which is pivotable by the transmission element, so that the retainer is released from the shoulder and the contact carrier is moved in the display position.
  • the device is housed in an auxiliary switch, which is not shown in the figures.
  • the auxiliary switch is associated with a motor protection switch, from which protrudes a transmission element 10, which acts on the device, which carries the reference numeral 11 in its entirety, according to the direction of arrow P 1 .
  • the transmission element 10 is a so-called moment slider.
  • the auxiliary switch contains the device 11 with a contact carrier 12, which is elongated cuboid-shaped and in the direction of its longitudinal extent according to arrow direction P 2 and P 3 is displaceable.
  • the contact carrier has two transverse openings 13, 14, each containing a pair of contact bridges 15, 16 and are penetrated by the contact bridge pair 15 and 16, wherein the pairs of contact bridges 15, 16 by means of contact pressure springs 17, 18 against the upper end walls 19, 20 of the installation position Breakthroughs are pressed.
  • At the contact bridges are each contact pieces (not shown), which can be brought into contact with above the contact bridges (in the assembled position) arranged fixed contact pieces.
  • an arm 19 is formed, which projects perpendicular to the longitudinal extent of the contact bridge 12 of this perpendicular thereto; the arm 29 runs parallel to the contact bridge pairs 15, 16.
  • a guide 22 is provided on the side facing the contact bridges, on which a compression spring 23 engages, which seeks to push the contact carrier 12 in the direction of arrow P, ie in the assembly position upwards.
  • a pressure surface 24 is arranged, via which the contact carrier 12 according to the direction of arrow P 13 against the force of the compression spring 23 can be pushed back into the interior of the auxiliary switch, if due to a short-circuit release of the contact carrier 12 is moved in the direction of arrow P 2 , so that the pressure surface visibly protrudes from the auxiliary switch housing.
  • a rotary arm 25 is rotatably supported at one end via a stationary shaft 26, wherein the axis of rotation 26 is parallel to the longitudinal extent of the contact bridges 15, 16 and parallel to the arm 21, thus perpendicular to the direction of movement P 2 , P 3 is rotatable.
  • the rotary arm 25 protrudes or depends on its axis 26 in the direction of the contact pieces. It has a projection 27, which is in operative connection with a nose 28 on the contact carrier, so that the contact carrier is pressed against the projection 27 of the lever 25 due to the force of the compression spring 23.
  • a pin 29 is integrally formed on the lever, which protrudes counter to the direction of movement P 1 from the auxiliary switch or projecting from the lever 25, so that this pin 29 is in communication with the torque slide 10.
  • auxiliary switch Within the auxiliary switch is a perpendicular and skewed to the axis 26 extending further axis of rotation 30, to which an arm 31 is formed, which protrudes in the direction of the contact carrier 13 and with a further projection 32 with another Nose 33 cooperates on the contact carrier.
  • arm 31 At the free end of the other arm 31 is a extending in the direction of the axis of rotation 30 locking arm 34 is formed at the free end of a nose 35 is arranged, which cooperates with a recess 36, which is described in more detail below.
  • a guide pin 37 engages a compression spring, which seeks to pivot the arm 31 about the axis of rotation 30, in the mounted position in the clockwise direction, so that the arm 34 is pressed against the torque slider 10 in the region of the return.
  • the momentary slide 10 is moved in the direction of arrow P 1 and presses on the arm 29, so that the lever 25 rotates clockwise about its axis 26 and the nose 28 is released from the projection 27, so that the Contact carrier 12 is moved in the direction of arrow P 2 due to the spring 23.
  • the detent 35 engages behind the recess 36, so that the torque slide alone can no longer be moved without further action into its triggering position against the direction of arrow P 1 .
  • the arm 34 thus holds the torque slide 10 by means of his nose 35 fixed.
  • the compression spring which acts at 37, holds the arm 34 in this locked position.
  • the lever has an inclined surface 40, with which it can be deflected by means of a tool, so that the projection 27, the nose 28 releases.
