Definitions

  • the present invention relates to a switching device which has a first switching point for the operational switching of at least one current path and a second switching point for switching off a short-circuit current.
  • the first and second switching points are connected in series.
  • switching devices in particular low-voltage switchgear, the current paths between an electrical supply device and consumers and thus their operating currents can be switched.
  • the connected consumers can be reliably switched on and off.
  • a low-voltage electrical switching device has one or more so-called main contacts for switching the current paths, which can be controlled by one or more control magnets.
  • a low voltage switching device may e.g. a contactor, a circuit breaker, a motor feeder or a compact starter.
  • the main contacts consist of a movable contact bridge and fixed contact pieces to which the consumer and the supply device are connected.
  • a corresponding on or off signal is given to the control magnets.
  • the control magnets act by means of their armature on the movable contact bridges such that the contact bridges perform a relative movement with respect to the fixed contact pieces. As a result, the current paths to be switched can be closed or opened.
  • the switching device can no longer switch off the load safely, even though there is a switch-off command for the control. In a welded contact then remains at least the current path with the welded main contact further current or live. The consumer is therefore not completely disconnected from the utility. Since the consumer remains in a non-safe state, the switching device is a potential source of error.
  • switching devices such as off DE 43 35 965 A1 known, consisting of two conventional and series switching devices, such as a contactor and circuit breaker or a contactor and overcurrent relay exist.
  • the contactor is used for operational switching (switching function) of a consumer, while the circuit breaker intervenes only in the event of a short circuit (protective function).
  • the two switching devices are usually connected to each other mechanically and electrically with a connection module.
  • Such a combination of switching devices is also referred to as a motor branch.
  • the circuit breaker switches off the short-circuit current. Due to the much higher short-circuit current compared to the maximum rated current, the switch contacts of the contactor weld. The reason for this is the high short-circuit current, which leads to an easy opening of the switching contacts. Between the switching contacts, an arc forms, which melts the contact surfaces of the switching contacts. When the short-circuit current decreases, the switching contacts close again, with the switching contacts welding together as the fused contact surfaces solidify. The contactor is defective after the short circuit.
  • US 5,541,561 A1 discloses a switching device according to the preamble of claim 1.
  • Object of the present invention is to provide a switching device which avoids the disadvantages mentioned above.
  • the first and second switching point are housed in a common housing. To connect the current paths, electrical connections and optionally a control connection for the input of a switching command in or on the housing are available.
  • the first switching point is designed for a maximum continuous current.
  • the second switching point is designed for (repeatedly) switching off a short-circuit current, which may be a multiple of the maximum continuous current.
  • the first switching point has at least one Main contact, which is by means of a Maisetzhaltesystems or Maiszuhaltesystems at least for the duration of a short circuit preserved or sustainable.
  • the contact holding system or the contact holding system prevents welding of the first switching point in the event of a short circuit.
  • the structure of such a switching device simplifies considerably.
  • a separate connection module for connecting the first and second switching point is not required.
  • the protective function of the switching device according to the invention is maintained both in the case of short circuit and in welded main contacts of the first switching means.
  • the main contacts of the first switching means are kept open or closed by the contact holding system or by the contact holding system. Damage to the main contacts does not occur. If one of the main contacts of the first switching means worn at the end of life and therefore welded, there is a shutdown of the current paths through the second switching point.
  • the first switching point only needs to be designed in such a way that it can (just) still be able to control a short-circuit current until it is switched off by the second switching point without damage.
  • the second switching point only needs to be designed for a maximum design short-circuit current.
  • Such a switching device according to the invention is consequently more compact and reliable.
  • the integration of the two switching points in a housing is an unwanted technical change or a non-optimal performance tuning the respective parameters of the two switching points on each other not possible.
  • the contact suspension system has a particular electromagnetic actuator which opens the at least one main contact by means of a contact slide in the event of a short circuit and keeps it open until the short-circuit current through the second switching point.
  • the actuator may for example be in a mechanical operative connection with the contact slide, which is connected for operational switching with a switching drive or control magnet of the first switching means.
  • the actuator can directly actuate the main contacts by means of a further contact slide which is independent of the previously mentioned contact slide.
  • the Kunststoffzuhaltesystem may have a particular electromagnetic actuator, which keeps closed the at least one main contact by means of a contact slide until the short circuit current through the second switching point.
  • the electromagnetic actuator of the Kunststoffetzhalte- or Kunststoffzuhaltesystems having an electromagnet.
  • the electromagnet is a submersible or lifting magnet, which is connected in at least one of the current paths for electrical excitation.
  • the actuator may have a particular mechanical, pneumatic, electrical or electro-mechanical damping device, which the actuated contact slide after elimination of electrical excitation can be driven back to the starting position after a delay time. It is essential that in a short circuit case as quickly as possible actuation of the main contacts takes place in order to hold or zuhalten. In particular, the actuation should take place within a few milliseconds. In contrast, the contact slide should drop only after a period of 20 to 200 milliseconds.
  • a mechanical damping device may, for example, have a spring system which, after the delay time, causes the contact slide to be damped back.
  • a pneumatic damping device may e.g. Have a pressure cylinder, which is acted upon in the event of a short circuit with compressed air and which only delayed can reduce the pressure.
  • An electric damping device may e.g. have a diode freewheeling circuit or a buffer capacitor. The stored electrical energy delays the degradation of the magnetic field which holds the actuator in the actuated position.
  • the second switching point has a short-circuit current detection, which outputs a control signal in the event of a short circuit.
  • the at least one main contact of the first switching point can then be opened by means of the electromagnetic actuator in response to the control signal.
  • the second switching point has a short-circuit current detection, which outputs a control signal in the event of a short circuit.
  • the at least one main contact of the first switching point is sustainable by means of the electromagnetic actuator in response to the control signal.
  • the short-circuit current detection of the second switching point can be done for example by means of a coil, a current transformer or a measuring resistor. That of the short-circuit current detection provided control signal preferably energizes or controls the electromagnetic actuator of the first switching point.
  • the control signal provided can be electrically buffered by the short-circuit current detection, for example by means of a capacitor, so that the electromagnetic actuator can retract into its rest position with a delay.
  • the signal can also be generated by means of an electronic time module or by means of a microcontroller, for example as part of the short-circuit current detection.
  • an electronic control unit such as e.g. the aforementioned microcontroller, take over control and monitoring functions of both the first and the second switching point.
  • the control tasks may relate to switching commands for switching the first and for triggering the second switching point.
  • the monitoring tasks may concern the short-circuit current monitoring and possibly an overcurrent monitoring in the device.
  • the electronic control unit may e.g. have a bus interface. In the event of an error or in the case of triggering the second switching point, a corresponding message, e.g. be sold to a higher-level control center.
  • the second switching point of the first switching point provides a short-circuit signal already detected by means of the short-circuit current detection as a control signal.
  • the second switching point has isolating contacts which can be opened in the event of a short circuit by means of a triggering mechanism.
  • the second switching point actuates a release ram in operative engagement with the release mechanism.
  • the second switching point has isolating contacts which can be opened in the event of a short circuit by means of a triggering mechanism.
  • the second switching point actuates a Zuhaltest maneuverel in operative connection with the release mechanism.
  • the Zuhaltest projects the at least one main contact of the first switching point is sustainable.
  • the Zuhaltestschreibel is operable at least for the duration of the short circuit.
  • the holding or Zuhaltest Jardinel is preferably mechanically coupled to the contact slide for opening the isolating contacts.

  • the switching mechanism or the triggering mechanism of the second switching point can be configured in such a way that the main contacts of the first switching point can be broken open via the stopping tappet of the second switching point. Welded main contacts are, as already explained above, especially at the end of life of the first switching means before.
  • the particular advantage of the two previous embodiments lies in the inventive interaction between the first and second switching point.
  • the second switching point mechanically actuates the main contacts of the first switching point to avoid contact welding in the short-circuiting case without the first switching point itself engaging.
  • the holding or Zuhaltestsonsel is connected to a particular mechanical or pneumatic damping device.

  • the magnetic field concentrator can also be C-shaped or V-shaped. It is crucial with respect to the geometric configuration and the arrangement in the first switching point that the magnetic field concentrator surrounds only the movable contact bridge without contact with the voltage and current-carrying parts of the switching device. It is also crucial that the magnetic field concentrator is designed to be semi-open in the region of the contact bridge.
  • the magnetic field concentrator according to the invention concentrates the magnetic flux in the end region of the U-shaped profile or the U-shaped yoke. Due to the local high magnetic field in the end region, the otherwise open-to-open contact bridge is pressed into the U-shaped profile in the event of a short circuit.

Opening the contact bridge is effectively prevented. It is prevented that the at least one main contact can weld before the short-circuit shutdown occurs through the second switching point.
  • the U-shaped profile of the magnetic field concentrator has legs of such a length that the leg ends are arranged for magnetic flux concentration at least approximately in the region of the contact bridge.
