Definitions

  • the invention relates to a switching device having a device for sudden switching with an actuating mechanism which has an actuating element and is operatively connected via a transmission mechanism with a switch lock, which operates a shift lever via a further transmission mechanism, and with a contact arrangement comprising a fixed contact piece with contacts has, which is opposite lying to a movable contact piece with contacts, which is guided in a contact slide.
  • Switching devices serve, among other things, the safe switching off in the event of a short circuit and thereby protect consumer installations.
  • electrical or mechanical switching units are suitable for the operational manual switching of consumers as well as for the safe disconnection of a system from the mains during maintenance work or when changing the system. Electrical switching units are often operated electromagnetically.
  • switching units are high-quality electrical switching devices with integrated protection for motors, lines, transformers and generators. They are used more closely at workstations with a lower switching frequency. Such switching units are suitable in addition to the short circuit protection for overload protection.
  • an electrical switching unit switches off an electrical system safely.
  • This provides a protection against overload.
  • Each conductor flows through the stream, heats up more or less strongly. The heating depends on the ratio of the current to the conductor cross-section, the so-called current density.
  • the current density must not be too large, otherwise by too high Heating may contaminate the conductor insulation or possibly cause a fire.
  • switching units are used as overcurrent protective devices.
  • Circuit breakers have two separate release mechanisms for overload and short-circuit protection. Both triggers are connected in series.
  • the short-circuit protection is provided by an electrical release that works almost instantaneously. In the event of a short circuit, the electromagnetic release unlocks without delay a circuit breaker of the circuit breaker. A switching armature disconnects the contactor before the short-circuit current can reach its maximum value.
  • switching units have a contact slide unit with a contact slide and a movable contact piece.
  • the movable contact piece also has electrical contacts.
  • switching units have first contacts to a power line. In an on state, the electrical contacts of the movable contact piece contact the fixed contacts of the switching unit. In the event of a short circuit, the electrical contacts of the movable contact piece are released from the fixed contacts, so that the flow of current is interrupted. Here, the movable contact is released from the fixed contacts.
  • circuit breakers In addition to their protective functions as overload and short-circuit releases, as already mentioned above, circuit breakers also fulfill the normative switching on and off of motors. To prove this function, the circuit-breakers must be able to switch on ten times the rated motor current according to the product standard. In order to be able to guarantee this limit load, it is necessary for the circuit breaker to close the double interruption of the three current paths in the form of a movable bridge with two contact points and two fixed contact points, almost simultaneously and in a step function.
  • the DE 19703977 C1 describes a switching device according to the preamble of claim 1. Accordingly, the object of the present invention is a switching device with a device for jumping To create switching, which avoids a contact lifting with possible contact welding.
  • a switching device with a device for sudden switching which has an actuating mechanism which has an actuating element and is operatively connected via a transmission mechanism with a switch lock, which operates a shift lever via a further transmission mechanism, and has a contact arrangement which a fixed contact with contacts has, which is arranged opposite to a movable contact piece with contacts, which is guided in a contact slide
  • the means for sudden switching comprises a switching mechanism arranged in the lever, which is arranged in operative connection to a locking member, which is operatively connected to a transmission member is, which acts on the movable contact piece of the contact arrangement.
  • the invention is characterized in that the bevelled surface of the side wall of the transmission member defines a distance c and thus a certain, defined period of time in which the switching device is brought into the on position, so that the closure of the flow path operator-independent, by the dynamics of the contact apparatus and its contact load spring is determined.
  • the three contact devices are pressed from movable and fixed contact pieces via a finger-shaped lever in the off position. This is associated with a defined distance a of the movable and fixed contact pieces from each other.
  • the switch lock begins to release the transmission element and thus the contact device via its lever, which undergoes a rotational movement. After a lead, the lever forces the locking part to follow its rotational movement, since both parts have the same bearing point.
  • the blocking member blocks the transmission member, so that the contact distance between the movable contact piece and fixed contact piece now maintains the distance b.
  • the distance b is kept constant until the locking member has passed through the distance c on the transmission member. While the transfer member blocks the contactor, the lever continues to rotate. After passage of the distance c, the transmission member is released, so that the contact apparatus can close the current path independently of the rotational movement of the operating part. Due to the positive guidance of the locking part on the shift lever is a constant release of the transmission element.
  • the essence of the invention is that the switch-on takes place independently of the rotational movement on the control panel.
  • the distance c determines the time for which the contact distance b is held. During this period, the control panel is placed in the on position, so that the Closure of the current path is not determined by the rotational movement on the control panel, but by the dynamics of the contact apparatus and its contact load spring. This leads to the fact that there is no time difference when closing the individual current paths with each other.
  • the contact load springs determine the dynamics of the movable contact pieces and not the rotary movement of the operating unit. Due to the close tolerance band of the contact load spring, the approximately constant weight of the bridges and the contact slide, there is an almost simultaneous closing of the flow path.
  • the positive guidance between lever and locking part leads to a constant timing of the switch-on and to a small tolerance chain and thus to a high accuracy for the distance b.
  • the respective switching device can be equipped device-specific with a corresponding locking part.
  • the inventive device for sudden switching is characterized by three components that are in operative connection with each other.

  • one of the two parallel side walls is smaller than the other and has a bevelled surface, which is in the switching device in operative connection with the wedge-shaped component of the blocking part.
