Definitions

  • Multi-pole vacuum switch with one pole drive unit for each vacuum interrupter
  • the invention relates to a multi-pole vacuum switch with a rectilinearly movable drive plunger vacuum interrupter per pole and a pole drive unit assigned to each vacuum interrupter, the pole drive unit having a lever arrangement for deflecting the drive force provided by a drive device common to all poles onto the drive plunger and approximately parallel to the movement Direction of the drive plunger arranged contact force spring and a housing supporting the lever arrangement and the contact force spring.
  • a vacuum switch of this type has become known from DE-A-34 14 016.
  • One of the properties of the vacuum switch described there is that the drive device is loaded by the contact forces of all poles when the vacuum interrupters are switched on. These forces are transmitted in a known manner from the lever arrangement via an insulating coupling rod to the drive device and have to be supported there.
  • the invention has for its object to reduce the stress on the drive device by the reaction of the contact forces. At the same time, a shift of the contact force springs as a whole is to be avoided when switching on and off by a one-sided fixed support, as is known per se (cf. DE-A-33 00 979).
  • the lever arrangement comprises two toggle levers, one of which is articulated to the drive tappet of the vacuum interrupter and the other is articulated to a support lever which is pivotably mounted at one end on the housing and which on its other end is connected to the contact force spring, the support lever in its rest position being approximately at right angles to the direction of movement of the drive tappet assumes the current position and the toggle levers of the ON position of the vacuum switch are close to their extended position.
  • the specified arrangement of the toggle levers ensures that most of the reaction of the contact force springs is supported in each pole in the lever arrangement itself and in particular in the housing receiving the lever arrangement.
  • the drive device of the vacuum switch and the parts serving to transmit the driving force to the pole drive unit are thus largely mechanically relieved. This relief occurs regardless of whether the toggle levers are in the forward or overstretched position.
  • the contact force spring is not moved as a whole during the switching operations, but can be supported at one end in a stationary manner, since a connection to the support lever belonging to the lever arrangement is required only at the opposite end.
  • the toggle lever connected to the support lever can be extended beyond the knee joint and the protruding lever part formed thereby can be designed as a coupling point with an insulating coupling rod connecting the drive device to the pole drive unit.
  • the connection of the coupling rod to the pole drive unit is facilitated because the knee joint bolt has no other function to perform than the connection of the toggle levers.
  • the length of the protruding lever part there is the possibility of influencing the transmission ratio of the lever arrangement.
  • the protruding lever part can have at least two passage openings arranged at different distances from the end of the one toggle lever connected to the support lever for selectively inserting a coupling bolt, through which the drive device is connected to the pole drive unit.
  • the transmission ratio of the lever arrangement can be changed slightly with unchanged movement of the drive device, for example if a vacuum switching tube with a larger or smaller switching stroke is to be used with an otherwise unchanged overall arrangement.
  • a favorable arrangement of the contact force spring in the polar drive unit can be achieved in that a crosspiece is arranged in the housing as an abutment of the support lever in its rest position and at the same time as an abutment for one end of the contact force spring designed as a helical compression spring, with a passage opening for a the opposite end of the contact force spring is provided with a connecting rod connecting the support lever.
  • FIG. 1 shows a side view of a pole of a multi-pole vacuum switch with a pole drive unit.
  • FIGS. 2 and 3 show, in an enlarged view compared to FIG. 1, a pole drive unit with adjoining parts.
  • FIGS. 4 and 5 show a housing of a pole drive unit as an individual part in two views.
  • Each switching pole 4 contains a vacuum switching tube 10 which extends with a vertical longitudinal axis between a pole head 11 and the pole drive unit 5 of the switching pole 4 in question. Details of the vacuum interrupter 10 are not shown, since any suitable interrupter can be used. In a known manner, the switching elements (not shown) of the vacuum interrupter 10 can be closed and opened by a linear movement of a lower connecting bolt 12 which projects into the pole drive unit 5.
  • the fixed contact piece of the vacuum interrupter 10 is connected to an upper connecting bar 13 via the associated connecting bolt and a clamping device, while the movable contact piece is likewise connected to a lower connecting bar 15 via a clamping device and a flexible current band 14.
  • the pole drive unit 5 has a cross-sectionally U-shaped housing 16 that as an individual part in FIG. 4 in a side view corresponding to FIG and is shown in Figure 5 in plan view.
  • Elongated holes 18 are arranged in parallel legs 17 of the housing 16 and serve to guide an articulated bolt 20 which connects the movable connecting bolt 12 of the vacuum interrupter 10 to an upper toggle lever 21 (FIG. 1).
  • a lower toggle lever 22 is connected to the upper toggle lever 21 by a knee joint pin 23 and likewise articulatedly connected to a support lever 25 by a connecting bolt 24 at its other end.
  • the support lever 25 is connected by a further hinge pin 28 to a pull rod 30 which carries an abutment 31 at the opposite end for supporting a contact force spring 32 designed as a helical compression spring.
  • the pull rod 30 extends through an "opening in a crosspiece 33, which is provided with pins 34 which engage 16 ( Figure 4) in rectangular openings 35 of the leg 17 of the housing.
  • the lower toggle lever 22 has a projecting beyond the fulcrum pin 23 projecting Lever part 36, which is provided with two through openings 37 for the optional insertion of a coupling bolt 38.
  • FIG. 1 shows an insulating coupling rod 39 which connects the indicated drive device 3 to the lever part 36.
  • FIGS. 2 and 3 The mode of operation of the pole drive unit 5 is shown in more detail in FIGS. 2 and 3, in which only the pole drive unit 5 with the adjacent parts is shown in a representation corresponding to FIG.
  • the support lever 25 bears against the crosspiece 33 at its end opposite the bearing pin 26 with a pretension given by the contact force spring 32.
  • the toggle levers 21 and 22 are in a bent position.
  • the existing between the toggle levers 21 and 22 Angle depends on an adjusting device which is arranged between the lower toggle lever 22 and the support lever 25. As can be seen in more detail in FIG.
  • the adjusting device comprises an eyebolt 40, the threaded shaft of which passes through a central part 41 of the support lever 25 which is U-shaped in cross section. Nuts 42 on both sides of the middle part 41 allow the position of the eye part 43 of the eye screw 40 to be adjusted relative to the middle part 41.
  • the connecting bolt 24 passes through the lower end of the lower toggle lever 22 and elongated holes 44 in the legs of the support lever 25.
  • the drive device 3 (FIG. 1) is released for switching on, the drive force is transmitted to the lever part 36 via the isolating coupling rod 39.
  • a larger or smaller transmission ratio results for the same angle of rotation of the switch shaft.
  • the adjustment device consisting of the eyebolt 40 and the nuts 42 on the underside of the pole drive unit 5 is easily accessible. It is therefore not difficult to carry out an adjustment of the toggle lever arrangement on the fully assembled circuit breaker 1.
  • the contact force spring 32 is supported on one side on the cross piece 33, so that its mass is not moved as a whole when switching. This avoids the tendency to natural vibrations and reduces the drive force to be applied compared to known arrangements in which the contact force spring is arranged in the course of the force transmission.
