Definitions

  • the invention relates to a switch disconnector with a Spring spring mechanism, the axis of which drives the switching mechanism, preferably actuated a selector shaft (preamble of the claim 1).
  • a switch disconnector is for example known from DE-43 05 746 C2. This can be used in operation required switching on and switching off satisfactory respectively. However, in an emergency situation, the claim occur after an immediate shutdown. This can for example, the failure of a fuse, the entry different phases or another disruption be.
  • circuit breakers for this provided, but the disadvantage of a very complicated Construction and thus correspondingly high manufacturing costs, as well as a large space requirement.
  • the invention can preferably be used in switch disconnectors, whose spring mechanism is independent of the direction of rotation, e.g. a so-called spring star spring mechanism.
  • the Invention can be used with particular advantage in a Load switch arrangement according to the above DE-43 05 746 C2.
  • the invention is not limited to this, i.e. also from Principle can be used with other switch designs.
  • a preferred embodiment of the invention is the subject of claim 2.
  • the possibility of a easy decoupling by moving or moving a bolt is fast acting on the one hand and also in constructive structure of the bolt itself and that of it coupling or decoupling spring axis and switching means drive very simple and safe.
  • the features of claim 5 contain an advantageous Arrangement where moving the lever on Abutment on the switching mechanism drive is moved so that it second phase, i.e. the switch contacts of the switch disconnector in the "off" position. Here too no manual intervention is necessary. This is a Advantage that not only relieves the operating personnel, but above all to hedge against any Inattentiveness of the operating personnel of great importance is. Upon completion of the second described above Switching phase, the bolt comes back into the locked position, so that spring spring mechanism and shift shaft together are coupled.
  • FIG. 1 shows the lower part 1 of the housing of a switch disconnector, that in his shown in Fig. 1 above Area of a magnet 9 which is only indicated in the drawing has, which by not shown leads and Controls is switched on in the event of a fault.
  • armature 9 When the magnet is switched on, its armature 9 'moves in the opposite direction the action of the spring 17 in the magnet interior and hereby moves a lever 8, the function of a slide switch or of a plunger and thus moves in the direction of arrow 22.
  • the lever 8 is with a relatively narrow guide part 6 guided in a guide slot 7 of the housing, the in the direction of the trajectory explained below runs. In this direction, a bend 8 ' of the lever 8 in Fig. 1 moved accordingly to the left.
  • This pin 13 is used at the same time the centering of the control shaft 2 by moving in whose lower end engages (Fig. 2).
  • the Latch 5, 5 'in the position shown in Fig. 4 and while overcoming the force of the spring 15, which strives is, the bolt 5, 5 'in the blocking or coupling position 1 and 3 to press.
  • a switching strip drive pulley 21 is non-rotatable connected to the control shaft 2. It intervenes with drivers 22 in recesses of switching strips 20, 20 'of the switch disconnector on.
  • the arrangement is such that with the aforementioned rotation of the control shaft in the position 5, the switching strips 20, 20 'in the “off” circuit this switch disconnector are moved. They remain in this "off” position until after the fault has been rectified Magnet 9 is turned off and under the action of the return spring 17 together with the lever 8 again the starting position 1 occupies. Then the switch disconnector can be operated by hand be moved to the switch position "On”. This causes a pivoting back of the roller 4 and thus the Clutch disc assembly 3, 3 'in the starting position according to Fig. 1. The switch disconnector is again for the normal switching operation is available.
  • the aforementioned leg spring 15 is extended by one of the corresponding Bolt 14 held and supported on another, likewise extended bolt 14 from.
  • Switching on and off occurs in normal switching operation in a known manner with the help of a spring jump mechanism, and although a grid star spring mechanism prefers the direction of rotation independently is working.
  • the automatic mode according to the invention is in normal operation Coupling and decoupling and also automatic, automatic switch-off of the switch disconnector at Malfunction.
  • the switch disconnector according to the invention can short circuit protection be upstream.
