Definitions

  • the invention relates to a drive device for switching a vacuum interrupter on and off with a pivotably mounted two-armed lever which transmits a drive force and a spring which acts on the lever and provides the contact force.
  • a drive device of this type is known from EP-B-0 159 960.
  • the invention has for its object to provide a drive device which also consists of as few parts as possible, but which, in contrast to the known drive device, is particularly suitable for actuation by a drive force acting approximately parallel to the longitudinal axis of the vacuum interrupter, and which is easily different strong spring force can be performed.
  • the spring is supported at one end on a stationary abutment and that the lever is guided in its bearing in a limited manner in a direction running approximately parallel to the direction of actuation of the switching tube.
  • the bearing which can expediently be designed as an elongated hole, allows the lever to be pivoted about its articulated connection with the drive tappet of the switching tube. This process occurs when switching on, when the two-armed lever is pivoted until it touches the contact pieces and then is lifted from the bearing by the driving force against the force of the contact force spring and moved in the guide. When switching off, the lever is first pivoted in its bearing until the contact pieces come into contact with each other and on given movements occur.
  • the drive device can be adapted to different paths and forces within wide limits.
  • the drive force can be introduced at one end region of the lever and the movable plunger of the vacuum interrupter can be coupled to the other end region of the lever, while the spring acts between the pivot bearing and the drive-side end region of the two-armed lever.
  • the spring is arranged to engage one end region of the lever and the pivot bearing of the lever is located between the point of application of the spring and the articulation of the movable plunger of the switching tube on the lever. In both embodiments, there are different lever lengths for the translation from the contact force spring to the contact pieces.
  • a tilt-free attack of the actuating and driving forces can be achieved in that the two-armed lever is formed from two brackets arranged parallel to one another, the distance between which corresponds at least to the diameter of the spring.
  • the spring can then be hung, for example, on a pin or bolt passing through the tabs or partial levers.
  • the lever and the spring can be mounted or arranged in a stationary frame, the side walls of which are arranged at least around the diameter of the spring from the tabs of the lever.
  • a spring or additionally the spring of the basic arrangement can be provided instead of the one spring located between the tabs of the lever in the spaces between the side walls of the frame and the tabs of the lever. This means that three different forces are available regardless of the type of spring provided.
  • a bolt passing through the lever or its parallel tabs and a bolt supported parallel thereto in the side walls of the frame can be provided with notches as positional safeguards for the optionally provided springs. This ensures that the spring forces act symmetrically on the lever.
  • FIG. 1 and 2 show schematically a basic embodiment of the invention.
  • a vacuum interrupter is shown in FIG. 1 with closed contact pieces and in FIG. 2 open contact pieces.
  • FIG. 5 shows a side view of a constructional embodiment which corresponds to the principle of operation according to FIGS. 1 and 2 and which is suitable for the optional use of one to three contact force springs.
  • FIG. 6 shows the section VI-VI in FIG. 5, but with the vacuum interrupter omitted.
  • FIG. 1 and 2 the drive device of a vacuum interrupter 1 is shown, which has a fixed connecting pin 2 with a fixed contact 3 and a movable plunger 4 with a movable contact 5.
  • the connecting bolt 2 also serves to fasten the switching tube 1 in a suitable and not closer ge shown way.
  • the drive plunger 4 is connected at its end by a joint arrangement 6 to a two-armed lever 7, at the opposite end of which the force used to switch on the switching tube 1 is introduced. This is indicated in FIG. 2 by an arrow and the identifier F.
  • the two-armed lever 7 can be pivoted about a bearing pin 8 which can be moved in an elongated hole 9 of a bearing block 10.
  • the elongated hole 9 is aligned approximately parallel to the longitudinal axis of the switching tube 1, ie parallel to the longitudinal axis of the connecting bolt 2 and the drive plunger 4.
  • the driving force F also acts approximately parallel to the longitudinal axis of the switching tube 1.
  • the switched-off state of the switching tube 1 is shown in FIG.
  • the two-armed lever 7 bears against a stop 12 under the influence of a helical tension spring 11.
  • the tension spring 11 is supported on the one hand on a stationary abutment 13 and on the other hand on a bolt 14 of the lever 7 which is located between the bearing bolt 8 and an end region 15 of the lever 7 provided for the application of the force F.
  • the bearing pin 8 lies against the end of the elongated hole 9.
  • the tension spring 11 determines both the hold-open force acting on the switching tube 1 in the position of the parts according to FIG. 1 and the contact force in the position of FIG due to the position of the bolt 14 between the end region 15 and the bearing bolt 8, these forces can be selected appropriately.
  • the two-armed lever 7 is likewise pivotably mounted and displaceably guided with a bearing pin 8 in an elongated hole 9.
  • the joint arrangement 6 for connecting the two-armed lever 7 and the switching tube 1 is not located at one end of the lever, but between the end region 15 and the bearing pin 8.
  • the tension spring 11 engages to an end region 16 of the lever 7, which lies opposite the end region 15.
  • the switching tube 1 is shown in the switched-off state.
  • the two-armed lever 7 assumes an inclined position under the influence of the tension spring 11, in which the hinge pin 8 in the elongated hole 9 represents the pivot bearing.
  • a force F is again applied to the end region 15 of the two-armed lever 7, but in the opposite sense to that in the previous exemplary embodiment.
  • the two-armed lever 7 first pivots about its bearing pin 8 until the switching pieces 3 and 5 of the switching tube 1 touch and the joint arrangement 6 on the drive tappet 4 acts as a pivot bearing.
  • the tension spring 11 is tensioned to apply the desired contact force.
  • FIGS. 5 and 6 show a construction example for a lever arrangement according to the principle shown in FIGS. 1 and 2.
  • the two-armed lever 7 here consists of two tab-like partial levers 20 (FIG. 6) which are arranged parallel to one another at such a distance that the tension spring 11 (FIG. 5) can engage between the partial levers 20.
  • the pin 14 is formed on both sides protruding beyond the partial lever 20, to the extent that additional tension springs can be hooked in if necessary.
  • the distance between the partial levers 20 and side walls 21 and 22 of a frame-like sheet metal part 23 is selected accordingly.
  • a holding bolt 24 serving as a stationary abutment for one or more tension springs is also supported in these side walls. Both the bolt 14 and the bolt 24 are provided with notch-like recesses 25 which prevent the springs from moving laterally.
  • the side walls 21 and 22 of the frame 23 also contain two elongated holes 9 for guiding the bearing pin 8.
  • the joint arrangement 6 comprises a bearing block 26 attached to the end of the drive tappet 3 with parallel surfaces corresponding to the spacing of the partial levers 20. Furthermore, the bearing block 26 carries pins 27 on both sides, over which the partial levers 20 engage. A flexible current band 30 connects the drive plunger 4 to a fixed connecting piece 31.
  • the frame 23 is attached to an insulating support plate 32, which can be common for a number of frames corresponding to the number of poles of the switching device.
  • the support plate 32 is in turn attached to an earthed base frame 34 via support insulators 33.
  • the arrangement shown can also be upside down, i. H. be arranged with the base frame 34 above if the switching device is to be attached, for example, to the top wall of a container filled with an insulating gas.
