Definitions

  • Such an actuator is well known. It is used in safety-related three-phase circuits to ensure safe emergency shutdown of the three-phase circuit, even if one of the contactors fails.
  • the drive unit is often located far away from the shooter.
  • a plurality of lines between the contactors and the drive unit to lay In particular, at least two supply lines and at least one feedback line must be installed per contactor.
  • the object of the present invention is to provide an actuator in which a safe emergency shutdown of the three-phase circuit is ensured with the least possible wiring.
  • the object is achieved in that the contactors and the drive unit are combined to form a unit assembled and disassembled built-in module.
  • both the supply lines and the feedback lines within the actuator unit can be fixed wired. Even the three-phase circuit can already be firmly connected in advance between the shooters.
  • the wiring effort is reduced even further if the emergency shutdown signal can be forwarded by the control unit via a safe output channel to a further actuator unit.
  • the actuator unit can also be used for operational opening and closing of the three-phase circuit.
  • the opening of the three-phase circuit is particularly safe when the drive unit for opening the three-phase circuit always disables all contactors.
  • the actuator unit can also be used in environments containing splash water and dust.
  • “High degree of protection” means protection at least to IP 54, better to IP 65, possibly even to IP 67.
  • the actuator unit has connectors for connecting the contactors to the three-phase circuit, the external wiring of the actuator unit can be accomplished very quickly.
  • the connectors are preferably accessible from outside the housing.
  • the actuator unit operates particularly reliably.
  • an actuator unit A has two contactors 1, 2 and a fail-safe control unit 3.
  • a three-phase circuit 4 can be opened and closed.
  • the contactors 1, 2 are designed so that the three-phase circuit 4 may have a rated voltage U of up to 1 kV. In particular, the nominal voltage can thus be 380 V and more.
  • the three-phase circuit 4 is opened as soon as at least one of the contactors 1, 2 is deactivated.
  • the actuator unit A has several safe shutdown channels 5. Via each of the safe shutdown channels 5, the drive unit 3 can be supplied with an emergency shutdown signal for the three-phase circuit 4. As soon as the drive unit 3 is supplied with an emergency shutdown signal via one of the safe shutdown channels 5, the drive unit 3 activates both contactors 1, 2 and deactivates them. As a result, both contactors 1, 2 open the three-phase circuit 4. Thus, the three-phase circuit 4 is safely opened even in the event of failure of one of the contactors 1, 2.
  • the drive unit 3 also has an input channel 6. About the input channel 6 of the drive unit 3, a drive signal for the three-phase circuit 4 can be fed. In the absence of the emergency shutdown signal, the drive unit 3 is therefore able to open or close the three-phase circuit 4 in accordance with the drive signal.
  • the contactors 1, 2 and the control unit 3 are combined to form an assembly module 7 that can be assembled and disassembled as a unit.
  • an assembly module 7 that can be assembled and disassembled as a unit.
  • a large part of the internal wiring of the built-in module 7 can be firmly pre-connected. Both the wiring costs when connecting the installation module. 7 as well as the risk of Fehlverdrahungen is thus significantly reduced.
  • the actuator unit A has a safe output channel 8. Via the output channel 8, the emergency shutdown signal from the drive unit 3 to a further, only schematically shown in FIG 1 actuator unit B can be passed.
  • the structure and operation of the actuator B essentially correspond to those of the actuator unit A.
  • the actuator unit B via an input channel 10, a drive signal for a three-phase circuit 11 can be fed.
  • the three-phase circuit 11 may have a rated voltage U of up to 1 kV. In particular, therefore, the rated voltage of the three-phase circuit 11 can also be 380 V and more here.
  • the drive signal for the three-phase circuit 11 may be different from the drive signal for the three-phase circuit 4.
  • the further actuator unit B has a safe output channel 12. About the output channel 12, the Notabschaltsignal can be passed from the other actuator unit B to another, not shown in FIG 1 actuator unit.
  • the actuator unit B has only one safe shutdown channel 13. This is also sufficient with the actuator unit B, since it does not have to monitor several safe shutdown channels. Because this task is performed by the actuator unit A. The actuator unit B must be able to respond only to an emergency shutdown signal forwarded by the actuator unit A.
  • the housing 14 is formed as a housing 14 high degree of protection, by means of which the contactors 1, 2 and the drive unit 3 are encapsulated by the environment.
  • "High degree of protection” means protection at least according to degree of protection IP 54, better according to degree of protection IP 65, possibly even according to degree of protection IP 67.
  • the actuator unit A has according to FIG 3 connectors 15 to 17.
  • the connectors 15 to 17 are accessible from outside the housing 14.
  • the contactors 1, 2 are connected to the three-phase circuit 4.
  • the connector 16 electrical energy is supplied to the shooters 1, 2 and the drive unit 3.
  • the drive unit 3 further signals, z. B. Notaussignale and normal control signals, fed. Furthermore, signals can be transmitted to the actuator unit B via the plug connectors 17.
  • the connectors 15 are assigned locking lever 18.
  • the connector 16 threaded holes 19 are assigned.
  • the connectors 17 are provided with screw threads 20.
  • the locking lever 18, the threaded holes 19 and the screw 20 form holding devices 18 to 20. With them are not shown, connected to the connectors 15 to 17 mating connector and / or not shown, on the connectors 15 to 17 patch covers against accidental loosening ensured.
  • the provision of the housing 14 with the connectors 15 to 17 and also the assignment of the holding devices 18 to 20 to the connectors 15 to 17 is of course possible regardless of the presence and the formation of the housing 14 as a housing 14 high degree of protection.
