Definitions

  • a vacuum switch of this type has become known, for example, in the Electrical Review magazine April 13, 1973, pages 531 to 533 and in the magazine Electrical Railways 78 (1980), number 8, pages 198 to 202. Further examples of vacuum switches of the type mentioned can be found in the catalog GB64 / 1949 on vacuum switches model VT-123 from Meidensha and in US Pat. No. 3,597,556.
  • the invention is particularly advantageously applicable to a vacuum switch of the type mentioned, in which the deflection gear comprises a toggle lever system, with the knee joint of which a drive is guided in its longitudinal direction rod is connected and the toggle lever transmit the movement of the drive rod with approximately right-angled deflection of the direction of movement to the mutually facing drive plunger of the switching tubes.
  • the lever mechanism for each switching tube comprises a two-armed lever, the pivot point between the ends of which is arranged on the drive plunger of the switching tube and the ends of which are indirectly or directly articulated to the deflection gear or to the abutment. In this way, the arrangement of the common abutment of the contact force springs is made possible at a location of the vacuum switch that is accessible. Furthermore, an arrangement with a stationary or with a moving contact force spring can be selected in this way.
  • the invention is also applicable to a vacuum switch in which the contact force springs are inserted into the deflection gear, as can be seen in US Pat. No. 3,597,556.
  • the contact force springs with its one end can be engaged by the drive rod facing the end of the two-armed lever and the drive rod ends of the two-armed lever facing away may be supported hingedly on q esonderten bearings of the abutment.
  • the synchronization of the switching tubes is also set here by loosening the drive rod and the abutment and reattaching these parts.
  • a space-saving arrangement of the vacuum interrupters with a relatively small mutual distance can be achieved in that the two-armed levers are cranked in the opposite direction with respect to the pivot points located on the drive tappets.
  • the lever arms of the two-arm levers facing the abutment can also be used as steering levers by selecting the bearing points such that the connecting line of the pivot points on the abutment and on the drive tappet from the right-angled position deviates only slightly from the direction of actuation of the switching tubes when switching on and off.
  • Fig. 1 shows a vacuum circuit breaker for the medium voltage range in a side view.
  • FIG. 2 and 3 are details of the drive of the. Switching tubes and the contact force springs shown in a side view. 2 shows the switch-off position and FIG. 3 the switch-on position.
  • Fig. 4 shows the drive parts in a front view with the attachment of the abutment of the contact force springs.
  • FIGS. 2 and 3 a further embodiment is shown in a representation corresponding to FIGS. 2 and 3. 5 shows the switch-off position and FIG. 6 the switch-on position.
  • the vacuum circuit breaker 1 shown in FIG. 1 is provided for the medium voltage range and is used in particular for supplying electrical tracks with single-phase alternating current of 16 2/3 Hz.
  • a total of three support insulators 3 are attached to a vertical support 2, the upper of which and the lower support insulator each carries a head piece 4, on each of which a switching tube 5 is clamped with its fixed locking bolt.
  • the two switching tubes 5 are arranged in alignment with one another, with a pole head 6 being located between them, which is supported via the third support insulator 3 with respect to the carrier 2.
  • a drive box 7 is fastened to the carrier 2 and contains all the parts required for providing and releasing the drive energy.
  • the structure of the drive device 7 is not explained in detail below, since such drive devices are known in various designs.
  • a drive device provided for vacuum switches is in the. DE-AS 27 17 958 (corresponds to US-PS 4 152 562).
  • the drive device 7 has a hand crank 10 in order to be able to charge an energy store, which is then released for activation by a trigger command.
  • An insulating switching rod 11 then executes a substantially rectilinear movement directed towards the pole head 6, while in the opposite direction when it is switched off set direction, ie in the direction of the drive device 7 (double arrow 12).
  • insulating struts 13 are arranged between the pole head 6 and the head pieces 4, which, in addition to the support insulators 3, absorb part of the forces occurring when switching on and off.
  • Each of the switching tubes 5 has an axially displaceable drive plunger 15, into which an eyebolt 16 is inserted and fastened by a nut 17.
  • a double-angled lever 21 is mounted on one side and a steering lever 22 on the other side.
  • the steering levers provide the necessary guidance for the displacement of the drive plunger 15 in the direction of the double arrow 23 in such a way that the stress on the guide bearing 15 of the drive plunger 15, which is not visible in FIG. 2, is kept as low as possible by transverse forces.
  • each two-armed lever 21 is connected in an articulated manner to a lever 25 of a toggle lever system 26, on the knee joint pin 27 of which the drive rod 11 engages.
  • a straight line guidance of the drive rod 11 and the knee joint bolt 27 is achieved by means of an elongated hole guide 30 in wall parts of the pole head 6.
  • the longer lever arm 31 of each two-armed lever 21 interacts with a contact force spring 32.
  • the contact force springs 32 are designed as helical compression springs and each enclose with their windings a guide rod 33 which are seated on a common bearing pin 34 at their inner ends. This is part of an abutment 35, which has approximately the shape of an approximately U-shaped Has bracket with outwardly angled leg ends 38 (Fig. 4).
  • one disk 36 is used, which rests on the bolt 34.
  • a further disk 37 is provided, which transmits the spring force to the lever arm 31 of the two-armed lever 21 via a roller 40 and a hinge pin 41 passing through it.
  • Each of the hinge pins 41 passes through an elongated hole 42 located in the outer end of each guide rod 33.
  • the leg ends 38 of the abutment 35 are provided with elongated holes 43 which are open towards the edges and through which screws 44 extend. Bends 45 of the pole head 6 serve as the contact surface for the leg ends 38 of the abutment 35. As can be seen; The elongated holes 43 extend parallel to the longitudinal axis of the contact force springs 32 (FIG. 4). After loosening the fastening screws 44, the abutment 35 thus moves into a neutral position under the influence of a difference in forces.
  • the contact force springs 32 with their guide rods 33 assume an angular position which differs only slightly from the straight-line position.
  • the knee joint pin 27 of the toggle lever system 26 stands near the left end of the elongated hole 30. If the drive rod 11 is shifted from this to the right by the drive device 7 shown in FIG. 1, the toggle lever system 26 works as a deflection gear and causes a simultaneous displacement of both drive plungers 15 in the sense of switching on. These movements are approximately perpendicular to the longitudinal direction and to the direction of movement of the drive rod 11.
  • the essential simultaneous contact and separation of the switching elements of the switching tubes 5 during the switching operations for the function of the vacuum switch 1 is achieved in the following way: First, the toggle lever system 26 is separated from the drive device 7, e.g. B. by loosening the drive rod 11 on the drive device 7 or on the knee joint bolt 27. Furthermore, the screws 44 of the abutment 35 are loosened. The switching tubes 5 now come into the switch-on position under the influence of the surrounding air pressure. The abutment 35 now moves under the influence of an approximately existing difference in force into a neutral position, which corresponds to the switch-on position of both switching tubes 5.
  • the two-armed levers 21 are directly and articulatedly connected to the deflection gear (toggle lever system 26), while the contact force springs 32 are likewise supported directly on the abutment 35 or a bolt 34.
  • FIG. 5 switch-off position
  • FIG. 6 switch-on position
  • the contact force springs are supported indirectly on the abutment, with the intermediary of the two-armed levers 21, while the two-armed lever in turn are indirectly connected to the deflection gear, with the interposition of the contact force springs.
  • the same reference numerals are used for the matching parts in order to facilitate the comparison.
  • These are in particular the switching tubes 5, the pole head 6 and the support insulator 3 and the drive rod 11, the plunger 15 with the eyebolts 16 and the nuts 17.
  • the contact force springs 50 are compression springs which are located in the toggle lever system 51 connected to the drive rod 11. Each contact force spring 51 is seated on a toggle lever 52 and is supported on it via a disk 53. The opposite ends of the contact force springs 50 each rest on a disk 54, which in turn transmits the spring force via a roller to a two-armed lever 55.
  • the toggle levers 52 are each provided with an elongated hole 56, into which a bearing bolt 57 engages at one end of each two-armed lever 55. As can be seen in a comparison of FIGS. 5 and 6, the contact force springs 50 are compressed when switched on, the position of the bearing pin 57 changing within the elongated hole 56.
  • the two-armed levers 55 are designed similarly to the levers 21 in FIGS. 2 and 3 and accordingly transmit the movement of the drive rod 11 to the switching tubes 5.
  • the two-armed levers 55 are, however, at their end facing away from the drive rod 11 mounted on an abutment 60 directly on separate bearing bolts 58.
  • This abutment is similar to the abutment 35 in FIGS. 2 to 4 as a bracket with legs angled on both sides and is attached to the pole head 6 so that it can be moved in the direction of the double arrow 61 after loosening fasteners and in the new Reattach position.
  • the setting process can be carried out in an analogous manner, as has already been described.
  • the drive rod 11 is separated from the drive, whereby the switching vessels 5 move into the closed position under the influence of the surrounding air pressure.
  • the fastening elements of the abutment 60 it is achieved that the entire mechanism consisting of springs and levers is in equilibrium and thus both switching tubes 5 are actuated synchronously after the abutment 60 has been fastened in the neutral position.
  • the two-armed levers 21 and 55 are cranked in opposite senses with respect to the pivot points located on the drive tappets of the switching tubes 5. 2 and 3 it can be seen that the cranking takes place in such a way that the two lever ends are at a greater distance from one another than the pivot points located on the drive tappets.
  • the two-armed levers 55 according to FIGS. 5 and 6 basically have the same shape, with a greater offset of the levers at their end facing the abutment 60 not being necessary. Rather, the position of the lever arms 62 of the two-armed lever 55 is selected so that they immediately take over the function of steering levers for the drive plunger 15.
