Definitions

  • the invention relates to a metal-enclosed switchgear with a gas-filled container and with a three-position switch arranged in the container for the switch positions ON, OFF and EARTHED, as well as with switching tubes of a vacuum switching device likewise arranged in the container, the container having bushings for connecting the three-position switch and the Vacuum holding tubes with components of the switchgear arranged on the outside of the container.
  • a switchgear with these features has become known, for example, from DE-A-42 11 155.
  • the vacuum holding tubes are part of a circuit breaker whose drive device is located outside the container filled with insulating gas.
  • the drive movement for the vacuum interrupters is conducted through the container wall to the vacuum interrupters by means of a gastight tappet bushing.
  • Switchgear with circuit breakers are not suitable for the operation of industrial systems with motors because they have to be switched on and off relatively often.
  • the drive devices of circuit breakers are designed for a relatively low switching frequency. It has therefore proven to be expedient to switch motor drives on and off at operational voltages in the lower medium-voltage range, for. B. 6 or 10 kV, vacuum switchgear in the form of contactors and to accommodate them together with other required components on a slide-in or trolley of an air-insulated, metal-encapsulated switchgear.
  • An example of this is shown in EP-B-0 263 396.
  • a switchgear comprises both the general energy supply of an industrial plant in the medium-voltage range and larger motor drives which are fed from the medium-voltage network
  • different types of switchgear panels are used, namely partially gas-insulated switchgear panels with vacuum circuit breakers and air-insulated switchgear boxes with vacuum contactors .
  • the invention has for its object to simplify the construction of switchgear of the type mentioned.
  • an electromagnetic drive device belonging to the vacuum switching device is likewise arranged in the container of the switchgear assembly and in that the vacuum holding device has the form of a contactor.
  • Commercial vacuum contactors can be used for the purposes of the invention. It should be noted that the electromagnetic drive device of such contactors is dimensioned for operation in atmospheric air and the function of the vacuum contactor can therefore be changed by a pressure of the insulating gas in the container of the switchgear which deviates from the atmospheric pressure. For the range of operating voltages of the lower medium-voltage range considered in connection with the invention, however, no pressure above the atmospheric pressure of the gas usually used as insulating gas sulfur hexafluoride is required.
  • a pressure which is slightly above atmospheric pressure and is suitable for preventing moisture or other foreign gases from diffusing into the container. It may therefore be sufficient to select a vacuum contactor in a standard version and to set its drive device in such a way as is the case, for example, for locations with increased air pressure, e.g. B. underground mining is provided.
  • Vacuum contactors with such an adjustment device are already known (DE-C-33 23 861). Since the electromagnetic drive of vacuum contactors only requires an auxiliary voltage from a low-voltage network, small and inexpensive bushings in the container wall are sufficient for supplying the operating energy. The small dimensions of these bushings allow them to be arranged at any suitable location on the container.
  • motor drives with operating voltages in the lower medium-voltage range form an important application of the invention.
  • the task of using a motor drive with changing direction of rotation, ie in turning operation, can also occur.
  • the two vacuum switching devices required for a motor turning control are accommodated in separate containers, additional bushings being provided on both containers for producing a phase crossing.
  • FIG. 1 shows a circuit diagram of a switchgear assembly with a three-position switch and a vacuum contactor.
  • Figures 2 and 3 show a metal-encapsulated, gas-insulated
  • Control panel with a vacuum contactor cut from the side or from the front.
  • Figure 4 shows two fields of a switchgear, each with a vacuum contactor for a motor turning control.
  • the circuit diagram according to FIG. 1 schematically shows a switchgear 1 with an overhead busbar 2, which runs outside a container 3 filled with insulating gas.
  • a three-position switch 4 which has the positions ON, OFF and EARTHED.
  • a connection of the busbar 2 to a likewise outside of the container 3, but expediently in the immediate vicinity of the HV fuse 5 is established.
  • a vacuum contactor 6 approximately below the three-position switch 4, on the outlet side of which a front bushing for a cable connection and two
  • Bushings are arranged in a lower container wall. While one of the lower bushings represents an additional outgoing connection, an overvoltage limiter 7 is connected to the other bushing. An electromagnetic drive device 8 belonging to the vacuum contactor 6 is also located in the container 3.
  • FIGS. 2 and 3 Further details of the switchgear according to FIG. 1 are shown in FIGS. 2 and 3.
  • the outlines of the metal-encapsulated switchgear 1 with the circuit according to FIG. 1 can be seen in more detail from FIGS. 2 and 3.
  • the container 3 has essentially flat wall parts, which, however, can be provided with a suitable stiffening in order to withstand an internal gas pressure above atmospheric pressure without substantial deformation.
  • the essentially cuboid-shaped container 3 is provided locally with recesses.
  • the container 3 has on its front side a recess as a support for a low-voltage box 10, in which operating and control elements and measuring devices are located.
  • a further recess is provided which corresponds approximately to the depth of cable angle plugs.
  • Such an angled plug 11 is shown in FIG. 2 in connection with a bushing 12.
  • the container 3 has a further indentation in the upper left area, which has the depth of insulating housings 13 for HV fuses (position 5 in FIG. 1).
  • the three-position switch 4 is arranged so that its axis of rotation extends horizontally and is accessible on the front 14 of the container 3.
  • a drive device 15 is also located there.
  • the vacuum contactor 6 is located below the three-position switch 4 in the lower region of the container 3 and is adjacent to the outlets 12 on the outlet side.
  • One of the lower bushings 16 is used to connect the overvoltage limiter 7 (FIG. 1), while the remaining bushing 17 is provided in the event that the switch panel shown is to be used in connection with an identical or similar switch panel for turning control .
  • the busbar 2 indicated in FIG. 1 is not shown in detail in FIGS. 2 and 3. However, 6 guides 20 shown, which serve to connect the three-position switch 4 to the busbar 2.
  • the bushings 12, 16, 17 and 20 mentioned are each provided in triplicate in accordance with the number of phases in the three-phase network.
  • the vacuum contactor 6 accordingly has three vacuum holding tubes 21.
  • vacuum interrupters 21 of different sizes are shown.
  • switch fields shown in FIG. 4 are only shown side by side to illustrate their circuitry, while in reality they are set up in alignment with one another.
  • the fact that the vacuum contactors belonging to a motor turning control are housed in separate fields of a switchgear and thus separate gas-filled containers means that standard containers can be used which are easier to replace in the event of a fault.
