Definitions

  • the invention relates to a switching device with a housing, which has a multi-pole Contact system and a switch lock includes, the switch lock has a drive lever connected to an operating lever, the acts on the contact system via a toggle lever system such that the drive lever to close the contact system in an on position and to Opening the contact system in an off position about an axis of rotation is arranged pivotably and one between the on position and the Has the off position, in which it is triggered by a appropriate trigger mechanism of the key switch when there is a Malfunction of the electrical system to which the switching device is connected is pressed to open the contact system, the toggle system at least two articulated with each other via a toggle lever axis connected toggle lever and a lock spring, which between the Toggle lever axis and the drive lever attacks.
  • Such a switching device is known for example from DE 33 36 207 C3.
  • EP 0 656 641 A2 is a switching device with undervoltage release known, which includes a leading auxiliary switch (VHI) (in in EP 0 656 641 A2 this auxiliary switch is referred to as button 10).
  • VHI leading auxiliary switch
  • Such Auxiliary switches are used to issue commands or signals, before closing or opening the main contact blocks of the switchgear be initiated and also allow a switch position indicator. Details This document contains information on the use of this auxiliary switch Not.
  • the drive lever in the presence of malfunctions in a tripped position between the off position and the on position depending on the arrangement, the respective drive lever takes the toggle lever system with respect to the axis of rotation of the drive lever, in the released position, there is often no precisely defined position. Much more the positions of the drive lever can vary from one switching operation to another and from switchgear copy to switchgear copy by a few Degrees differ from each other.
  • the invention has for its object a switching device of the aforementioned Specify which one is an interchangeable undervoltage release with integrated auxiliary switch, with the auxiliary switch safely in a predetermined position of the drive lever within the tripped position is operated.
  • the invention is essentially based on the idea in the tripped position to let a sufficiently large force act on the drive lever, which pivots this securely into its predetermined position, around the To operate auxiliary switch.
  • This can e.g. done in that the axis of rotation of the drive lever and the toggle lever axis are arranged in such a way that when reaching the tripped position taking into account the spring force the lock spring a torque acting on the drive lever results, which is sufficient to the drive lever against the pressure of the actuator the auxiliary switch to its defined position.
  • such an embodiment of the invention has the disadvantage that the switching device and the associated undervoltage release each must be adapted to each other through constructive measures so that taking into account all other interface parameters large torque can be applied by the drive lever. If you change the size of such a switching device (the same Switchgear series), the dimensions of the associated usually change Undervoltage release.
  • the Swiveling the drive lever by at least one additional elastic Element takes place, which the drive lever against the pressure of the mechanical Actuator of the auxiliary switch in the defined position pushes or pulls.
  • Tension, compression or torsion springs can be used as elastic elements be used.
  • a switchgear series with switchgear different Size can also be provided such that a first switching device is designed so that the pivoting movement of the drive lever by the different position of the toggle lever axis and the axis of rotation of the drive lever is generated and that the other larger and / or smaller Switchgear is equipped with an additional spring to the drive lever to pivot into its defined position.
  • 1 denotes a switching device with a housing 2, which in a lower housing part 3, not shown, with busbars 4, 5 connected multi-pole contact system and in its upper Housing part 6 a key switch 7 with a not shown (in front of the image plane ) undervoltage release.
  • the key switch 7 has one connected to an actuating lever 8
  • Drive lever 9 on the toggle lever system 10 on the contact system acts in such a way that the drive lever 9 for closing the contact system in an on position labeled I and for opening the contact system in an off position labeled "0" can be pivoted about an axis of rotation 11 is arranged.
  • 1 and 2 there is the drive lever 9 and thus also the operating lever 8 in a between the on position and the off position tripped position, in which he is in the presence of a Malfunction of the electrical system to which the switching device 1 is connected by one (from the undervoltage release or by another Triggering mechanism activated), not shown, trigger mechanism of the key switch 7 is pressed to open the contact system.
  • the toggle lever system 10 has two articulated via a toggle lever axis 12 interconnected toggle levers, of which for reasons of clarity only the lower toggle lever 13 acting on the contact system is shown is.
  • the toggle lever system 10 comprises a lock spring 14, which between the toggle lever axis 12 and the drive lever 9 attacks. Since at Switching the switching device 1 on and off the tilting points of the lock spring 14 should be at different positions of the swivel path, also changed the toggle lever axis 12 in the corresponding switching operations, in Position seen in the swivel direction.
  • the drive lever 9 is bent (rearward) in a U-shape and points to it the side facing the undervoltage release, several switching cams 15-17 to control it.
  • the designated 15 and 16 serve Switch cams for actuating a control lever 18 and a trigger lever 19 (see Fig. 3 and the aforementioned DE 198 53 901 C1).
  • the one labeled 17 Switch cams actuate the push button 20 of the auxiliary switch 21 designed as a pressure switch as soon as the drive lever 9 is in its tripped position.
  • an auxiliary spring 24 (in the illustrated embodiment a tension spring) is provided on the one hand on the drive lever 9 and on the other hand on a part fixed to the housing (e.g. the frame, inside whose drive lever is pivotable) supports.
  • a leading auxiliary switch 21 provided with a push button 20 provided that e.g. with a first pair of contacts an electromagnet of the undervoltage release switches and with a second pair of contacts causes a switch position indicator.
  • This undervoltage release 26 should preferably be of different sizes Switching devices 1 are used without himself regarding its size needs to be changed.
  • FIG. 4 A corresponding switching device 1 (without the lower housing part) is shown in FIG. 4.
  • the same parts as those shown in Fig.1-3 Embodiments were used with the same reference numerals Mistake.
  • the housing 2 of the switching device 1 has in particular a chamber 28 for the undervoltage release acting on the switch lock 7 26th
