Definitions

  • the invention relates to an electromagnetic switching device, the control circuit containing the actuating coil contains both a switching contact acting as a break contact of a monitoring or protection device and a closing contact acting as a closer, manually operated switch contact, both this closer and the main contacts with the armature of the magnet system of the electromagnetic switching device are motion-coupled and the normally open contact in the control circuit of the actuating coil is actuated in front of the main contacts, as a result of which the armature is electromagnetically attracted.
  • the invention has for its object to provide a switching device of the above type, which ensures with little effort using the switch position indicator as an actuator that the switching on of the electromagnetic switching device in the presence of NC contacts, which are operated by monitoring or protective devices, prevented with certainty becomes.
  • This object is achieved in a simple manner in that a projecting beyond the contour of the switchgear housing, displaceable, holding the make contact and the main contacts is arranged in such a way that with maximum actuation travel of the contact bridge support by hand beyond the projecting part serving as a switch position indicator, only the make contact is closed and the main contacts are still fully open.
  • the switching device is housed in a housing, it is advantageous if an extension plunger which actuates the projecting part of the contact bridge support and is displaceably guided in an additional housing is provided and the extension plunger has an actuating foot with such a large area that further pressing in over the contour of the Switchgear housing protruding part of the contact bridge support under the contour of the switchgear housing is automatically prevented.
  • the three-phase motor 1 is connected to the mains supply lines phase 4, 5 and 6 via the electromagnetic switching device 2 and the overcurrent release 3.
  • the actuating coil 7 of the electromagnetic switching device 2 is connected on one side to the MP conductor 8 and is connected to phase 6 with the other connection phase via the normally open contact 11 of the electromagnetic switching device 2, the off button 10 and the break contact 9 of the overcurrent release 3.
  • the normally open contact 11 is formed so that it switches on in front of the main contacts 12, provided that the part of the contact bridge support 13 of the electromagnetic switching device which projects beyond the housing 14 of the electromagnetic switching device and which serves as a switching position indicator is actuated.
  • the part protrudes only so far that only a contact bridge can come into contact with the fixed contact parts 15, 16, indicated by dashed lines in FIG. 3, without the aid of tools or other aids.
  • the contact bridge with the fixed contact parts 15, 16 forms the make contact 11.
  • the main contacts 12 are also indicated by dashed lines in FIG. 3. They are arranged below the leading NO contact 11.
  • the actuation of the switch position indicator 13 can be actuated by means of an extension plunger 17 which is displaceably mounted in the wall 18 of an additional housing.
  • the actuating foot of the extension plunger 17 can have such a large area that the switch position indicator 13 is automatically prevented from being pushed further into the contour of the housing 14. The same success can be achieved with a hollow at the foot of the extension plunger 17.
  • the leading contact is also a main contact.
  • the actuating coil 7 is advantageously here with its one connection via the break contact 9 of the overcurrent release 3, the off button 10, the leading normally open contact 11 and the overcurrent release 3 itself at phase 6 and with the other connection on the MP conductor 8.
  • the here The circuit shown can be used in particular for smaller outputs where a two-phase shutdown is permissible. It has the advantage of saving additional auxiliary contact.
  • the extension plunger 17 or the switch position indicator 13 is now pressed in, the leading NO contact closes.
  • the main contacts 12 are still fully open at this moment.
  • the actuating coil 7 receives voltage from phase 6 according to the example of FIG. 2 via the overcurrent release 3, the normally open contact 11, the off button 10 and the break contact 9; the other side of the actuating coil 7 is located on the MP conductor 8, so that the current flows through the actuating coil and ensures that the electromagnetic switching device 2 is switched on again.
  • the static friction is already overcome, so that the magnet system of the electromagnetic switching device can pull through more easily, d. H.
  • break contact 9 which in the present case is acted upon by the overcurrent release 3, or other break contacts which are looped into the circuit and are operated by monitoring or safety devices, are not closed at the moment when the switch position indicator 13 is actuated, the electromagnetic switching device cannot be switched on , d. H. A perfect shutdown is guaranteed in the event of a malfunction with the appropriate free trip.
  • circuit arrangement according to the invention and its construction can significantly reduce the wiring effort and also the material expenditure with regard to additional buttons and contacts, without questioning the safety of the device.
