Definitions

  • the invention relates to a motor starter with a mechanical unlocking, via which the unlocking is formed by a terminal module.
  • Motor starters can have either direct or indirect, that is, hardwired wiring. With a motor switch with a direct wiring system switched on, it is possible for the operator to release under load, that is, under voltage, the plug connection or the connections of the motor. At the junction of the motor output are usually higher voltages and currents. It is therefore possible that an arc is created which can cause personal injury or equipment damage.
  • Motor starters with indirect that is fixed wiring
  • the terminal module is a rail system that carries the wiring of the motor starter to be locked.
  • the operator can plug the motor starter onto the rail system or disconnect it from the rail system without having to loosen the wiring.
  • an unlocking must be actuated. This can also lead to an arc that leads to personal injury or equipment damage.
  • a warning is therefore placed on the devices in the manual or directly on the device, which indicates that the device or a cable may not be removed under load.
  • the technical solution used so far provides that the supply voltage of the switching element is interrupted so as to initiate a shutdown. This can be achieved for example by a pivoting movement of the motor starter, in which solve the connectors.
  • the object of the present invention is to provide a motor starter with an indirect, that is, fixed wiring, to a terminal module that ensures safe electrical isolation when the motor starter is pulled from the terminal module.
  • this object is achieved by a motor starter with a mechanical unlocking, via which the unlocking is formed by a terminal module.
  • the invention is characterized in that the mechanical unlocking is connected to an evaluation unit, which generates a switch-off command via a control, wherein the mechanical release is delayed in time until the switch-off is completed.
  • the operator must activate a mechanical unlocking procedure when removing the motor starter from the terminal module.
  • This mechanical release is connected to an integrated evaluation in the device.
  • a contact ie a switch, button or a touchless system is operated accordingly.
  • This generates a shutdown command that initiates a forced shutdown.
  • This forced shutdown corresponds to a regular shutdown.
  • the motor starter can thus be taken without power from its holder, that is, from the terminal module. Before the motor starter can be pulled out, the motor is already switched off automatically and prevents pulling under load.
  • the invention is to discern the intent of pulling and to bring about a targeted shutdown of the engine starter, at the same time the time until the mechanical operation is delayed until the shutdown is completed.
  • the power supply and the communication of the motor starter are still guaranteed at the time of switching off, whereby this state can be reported to the higher-level control.
  • Another advantage of the motor starter according to the invention is that in devices with higher power requirements, a lower buffering of the supply voltage is needed.
  • the motor starter according to the invention can no longer be pulled under load from the terminal module. This prevents personal injury or damage to the device. A possible carelessness of the operator is thus intercepted.
  • both the power supply and the communication of the motor starter is still guaranteed at the time of switching off. This makes it possible that this state can be reported to the higher-level control.
  • the mechanical unlocking is formed by a linear movement of the motor starter.
  • the motor starter is released simultaneously by the mechanical release on both sides and disconnected linearly from the terminal module, not in the form of a swivel movement. This linear movement of the mechanical unlocking prevents unintentional unlocking by improperly loosening one side.
  • a forced shutdown is provided via the switch-off.
  • the motor starter switches off the connected motor.
  • a takeover of the current is formed by semiconductors, and a shutdown is subsequently provided. This leads to a wear-free shutdown.
  • the motor starter according to the invention has a mechanical unlocking, which is electronically connected to an evaluation unit.
  • the evaluation unit is connected to a power supply and a communication. Both the function of the power supply and the communication function of the motor starter are still guaranteed when switching off, as a result of which this status can be reported to a higher-level controller.
  • the evaluation unit is also connected to a control, which drives the contacts in the main current paths of the motor starter.
  • the motor starter according to the invention is characterized by a state recognition for the mechanical unlocking of a terminal module, which detects the intent to disconnect the motor starter from the terminal module, and causes a targeted shutdown of the motor starter, while the mechanical process is delayed until the shutdown is completed.
  • the power supply and the communication of the motor starter are still guaranteed at the time of switching off, whereby this state can be reported to the higher-level control. It is therefore no longer possible to disconnect the motor starter under load from the terminal module, thereby avoiding personal injury or damage to the device. A possible carelessness of the operator is thus intercepted.
  • the motor starter according to the invention has a mechanical release 1, which is connected to an evaluation unit 2.
  • the evaluation unit 2 is connected to a power supply 3 and a communication 4. Both the function of the power supply 3, as well as the communication function of the motor starter are still guaranteed at shutdown, whereby this state can be reported to a higher-level control.
  • the evaluation unit 2 is also connected to a control 5, which drives the contacts 6 in the main current paths 7 of the motor starter.
  • Fig. 2 shows the mechanical release of the motor starter from the terminal module 8 via a linear movement.
  • the linear movement provides that the mechanical unlocking, which allows the disconnection of the motor starter from the terminal module 8, is pulled and subsequently the motor starter is moved in a straight motion away from the terminal module.
  • the motor starter according to the invention is characterized by a state recognition for the mechanical unlocking of a terminal module, which detects the intent to disconnect the motor starter from the terminal module, and causes a targeted shutdown of the motor starter, while the mechanical process is delayed until the shutdown completed is.
  • the power supply and the communication of the motor starter are still guaranteed at the time of switching off, whereby this state can be reported to the higher-level control. It is therefore no longer possible to disconnect the motor starter under load from the terminal module, thereby avoiding personal injury or damage to the device. A possible carelessness of the operator is thus intercepted.
