Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • An electrical circuit breaker, a motor protection switch or a circuit breaker has the task of switching off this error in the event of a fault in the network.
  • a fault may be a so-called overcurrent or a short-circuit current. While an overcurrent does not necessarily indicate a serious fault in the network, a short-circuit current indicates that there is a fault in the network that must be repaired.
  • circuit breakers, circuit breakers or circuit breakers alone can not detect whether it is a disconnection via an overcurrent or a short-circuit current, measures must be taken to be able to recognize this.
  • a signaling device for signaling a short-circuit and / or overcurrent trip preferably in conjunction with a circuit breaker or a motor protection switch, known.
  • the reporting device or the device for reporting in a Attachment used which is suitably coupled to the switching device.
  • the device according to the DE 93 02 254 U1 is in the starting device, which can be referred to as an auxiliary switch, both an apparatus for the detection of an overcurrent and a device for the detection of a short-circuit current having a relatively complicated lever mechanism.
  • the object of the invention is therefore to provide a device of the type mentioned, which is further simplified and which can be applied substantially at a tripping by a short-circuit current.
  • the contact carrier is held by a retaining device in its initial position and thereby spring-loaded from its initial position in the direction of the short circuit indication.
  • a short-circuit current moves the transmission element, which transmits the triggering of the switching device in the device, the retainer so that it releases the contact carrier and the contact carrier is also released in its movement in the direction of the short circuit indication.
  • the device according to the invention accordingly has only one component which holds the contact carrier, and this is the holder, which is movable about an axis perpendicular to the direction of movement of the contact carrier and holds in one position the contact carrier and releases the contact carrier in a second position.
  • a nose is formed in a preferred manner, which strikes against movement of the contact carrier towards short circuit indicator against the retainer and this blocked and vice versa, a projection is provided on the retainer, which acts in the short circuit display position on a release lever in the switching device and holds this in the exemption, so that the switching device can not be turned on.
  • the retainer is designed to cooperate with a transmission element such that the transmission element pivots the retainer, so that the contact carrier is released.
  • a pressure surface for pressing back in the rest position is provided in a preferred manner, since the device does not automatically return to its initial position or rest position.
  • the molded on the contact carrier nose the retainer, d. H. released the rocker when pressing the contact bridge.
  • the only schematically illustrated device 10 for signaling and display of a tripping due to a short-circuit current in a motor protection switch 11 is laterally attached to this and connected thereto in a manner not shown.
  • the motor protection switch 11 has some components, such as thermal bimetals, electromagnetic triggers, contact points and a switch lock, which are of little importance to the invention.
  • a transmission element 12 which is arranged displaceably in the direction of arrow P and engages in the auxiliary switch 10 with an L-shaped projection 13.
  • a contact carrier 14 which has two openings 15 and 16, in which contact bridges 17 and 18 are held, wherein the contact pressure of the contact bridges 17 and 18 is generated by a respective compression spring 19 and 20.
  • the contact bridges 17 and 18 cooperate with fixed contact pieces (not shown), and the contact carrier 14 is in a position in which the contact bridges 17 and 18 are separated from the stationary contact pieces.
  • a pressure surface 21 is formed, via which the contact carrier 14 according to arrow P 1 in the figure shown starting or rest position against the pressure of a spring 22 which is formed as a helical compression spring and a pin 23 is guided, is pressed.
  • a retainer 24 is rotatably supported via axes 25, wherein the free end 13 of the transmission element 12 cooperates with the retainer 24.
  • the centrally mounted retainer 24 has an arm 26 against which or cooperates with the L-shaped projection 13, and an opposite arm 27, on whose the motor protection switch 11 side facing a projection 28 is provided, which engages in the motor protection switch 11 (although this is not shown) and with the trip lever in the motor protection switch 11, which is also not shown, so cooperates that he holds this in free trip, whereby the motor protection switch can not be turned on.
  • a pin 29 is formed on the holder 24 side facing a pin which extends parallel to the axis of rotation 25 of the retainer 24; on the arm 27, a cam surface 30 is formed, which is in the path of the pin 29 in the direction of arrow P 2 .
  • the retainer 24 is pivoted about its axis counterclockwise. As a result, the retainer 24 releases a retaining lug 31 provided on the contact carrier 14, so that the contact carrier 14 is moved upward in the direction of the arrow P 2 due to the force of the spring 22, ie out of the auxiliary switch 10.
  • the pin 29 then applies to the surface 30 and holds the retainer 24 fixed in this display position, so that via the now closed contact points with the movable contact bridges 17, 18 signaling is given and a provision of the retainer 24 is avoided.
  • torsion spring which holds the retainer 24, in the starting position or supports this.
