Definitions
- the invention relates to a metal-encapsulated, gas-insulated high-voltage switch according to the preamble of claim 1.
- the movable contact piece is assigned a piston arrangement with an insulating nozzle, in which the gas pressure is increased during a switch-off operation and supplied to the arc.
- the actual quenching chamber i.e. H. the area where the arc is extinguished from the rest of the encapsulation area either via an insulating cylinder or separated in that the insulating nozzle in a guide cylinder is guided on the contact housing of the fixed contact piece.
- the object of the invention is to provide a high-voltage switch of the type mentioned To create a way that also creates a disconnect function.
- the contact housing can also be in addition to the normal one Switch-off movement are driven so that by actuating the contact housing the same function of a separation section is generated.
- the switching device which is a high-voltage circuit breaker and has the reference number 10 as a whole, contains a fixed contact piece housing 11 in which a rod-shaped fixed contact piece 12 is arranged; how the fixed contact piece is held within the fixed contact housing 11 is of no importance for the invention.
- the switching device 10 also has a movable contact piece 13, which is attached to a switching tube 14 and is surrounded by an insulating nozzle 15, which has a section 16 with the smallest diameter, which extends towards the fixed contact piece 12 via a conical region 17 to a section 18 large diameter expanded.
- the fixed contact piece 12 passes through the section 16 and the movable contact piece 13 in the switched-on state and via channels 19 arranged in the insulating material nozzle 15 is supplied according to the direction of arrow P to the arc 20 which is burning through the section 16 insulating gas, here SF 6 gas, so that the Arc 20 is blown and goes out.
- the gas flow P can be generated by an additional volume (not shown), possibly using the energy of the arc 20 itself.
- Such switches are known as so-called blow piston or auto blow switches. However, the invention is not limited to such switches.
- the movable contact piece 13, the drive tube 14 and the insulating nozzle 15 are in housed a housing 21; additional contact pieces that carry the nominal current are not shown for the sake of clarity.
- Metal encapsulation 30 housed, which is cylindrical in a single-pole arrangement and if necessary is oval in the case of a multipole arrangement. It is up to his End faces connected by a cover 31 and 32 and in the area of the end faces are, forming a V-shape, leads 33 and 34 transverse to the central axis of the metal encapsulation 30 provided, which are designed as cable terminations and through which Live conductors 35 and 36 are passed.
- the conductor 35 is movable Contact piece within the contact housing 21 electrically connected;
- An extension 37 is arranged on the fixed contact housing 11, which is guided by a guide 38 with the interposition of so-called multi-lamella contacts 39 which is electrically conductively connected to the conductor 36.
- a drive 40 which has a piston-cylinder arrangement 41, the piston rod 42 via a deflection lever arrangement 43 which is mounted in the axis of rotation 44, is connected to the drive rod 14.
- the connected to the fixed contact housing 11 Extension 37 is by means of a coupling rod 45 with a lever arrangement 46 connected, which is rotatably mounted at 47 and connected to a drive 48 which, like the drive 40, has a piston-cylinder arrangement 49, whose piston rod 50 is connected to the deflection lever arrangement 46.
- the drive 48 can also be done with a motor spindle assembly because of the movement by the drive 48 is relatively slow compared to the movement that the drive 40 executes, since only a separating movement has to be made.
- the disconnector movement can also be done by a drive on the same Side is arranged as the drive 40 when to achieve the disconnector movement the contact housing 21 is moved. Then the contact housing 21 must have appropriate Contact elements, the z. B. correspond to the multi-blade contacts 39, related guided displaceably on the conductor 35 and connected to it in an electrically conductive manner his. In this case, a two-position drive would be used as drive 40, which first executes the circuit breaker movement and then connects the disconnector movement.
- the drive 48 could also be on the same one Be arranged as the drive 40; in this case, the drive 48 would Move contact housing 21.
- the metal encapsulation 30 is supported on legs 51, 52 on the floor N-N.
- the 1 is the switch-on position, whereas in FIG. 2 the switch-off position of the switching device 10 is shown, which is illustrated in Fig. 4. you recognizes the insulating nozzle 15 between the contact housing 21 of the movable contact piece and the fixed contact housing 11. In the shown in Fig. 2 and Fig. 4 Position, the arc is blown and extinguished.
- the contact housing 11 is moved by means of the drive 48 moved in the guide 38 to the right, so that between the free end a distance t is formed between the nozzle 15 and the free end of the housing 11. This 3 is the disconnected position.
- the electrical switchgear other than the insulating nozzle between the contact housing 21 and the fixed contact housing 11 still has an insulating cylinder, such as it is represented, for example, by the dashed line 51 in FIG. 4, then also the insulating cylinder 51 together with the insulating nozzle 15 in the switch-off direction moves and the fixed contact housing 11 is also separated from the Isolation cylinder separated.
- the separation distance t is necessary, see FIG. 3.
- the invention is illustrated using a so-called dead tank switch; Of course The invention can also be used with any other gas-insulated switch become.
