Definitions
- the present invention relates to electrical substations high voltage.
- a first object of the invention is to design a circuit breaker-disconnector assembly cost lower than that existing sets, in particular by replacing the high cost rotary column switches by means of more rustic building switches and therefore more economical.
- a second object of the present invention is to define a circuit breaker-disconnector assembly requiring a reduced floor space.
- the present invention relates to a set circuit breaker for high electrical substation voltage characterized in that it comprises, per pole, at least a breaking chamber placed at the end of a first insulating column comprising a first and a second power outlet, and a disconnector comprising a second fixed column and a pivoting column that can pivot around of a tree in the vertical plane containing the first and second columns and at the end of which is placed a connection member capable of cooperating with said second power outlet, a cable connecting said end of the pivoting column at the top of the second column, a anti-roll connecting rod connecting the top of the second column to a point on the cable.
- the point of attachment between the connecting rod and the cable is located substantially in the middle of the cable.
- the connecting rod includes two arms connected by a pivot axis horizontal.
- the connecting rod is metallic with axis isolated.
- the point of attachment between the connecting rod and the cable is fitted with a corona guard.
- a counterweight is attached to the rotation shaft of the swivel column.
- the end of the counterweight is recessed.
- the set includes an earthing switch having the same rotation shaft as the swivel column and can rotate in a vertical plane.
- the earthing switch includes a member connection capable of cooperating with a connection member complementary to the end of the pivoting column.
- the earthing switch includes a counterweight.
- the switch-off switch to the earth partly rests in a ground gutter.
- the disconnector is horizontal plug-in.
- the disconnector is vertical plugged in.
- the second column is that of an intensity transformer.
- the cable is multiple.
- Reference 1 designates a switching chamber of a circuit breaker; the breaking chamber is arranged vertically at the top of an insulating column 2 placed on a metal structure 3 carrying a control 4.
- circuit breaker is only given by way of example, the invention applying to any type of circuit breaker, and in particular to multiple circuit breakers break chambers per pole, arranged horizontally or in V.
- the switching chamber has a first outlet for current 5 which connects it to an overhead cable 6 or to a bar rigid. It includes a second socket 7 for its connection to a disconnector.
- This disconnector includes a pivoting column 11 and a fixed column 21. These columns are arranged in the same vertical plane containing also the circuit breaker column.
- Column 11 includes a metal portion 11A extended by an insulating part 11B terminated by electrical connection members 12 able to cooperate with the second socket 7 of the circuit breaker.
- the column 11 can pivot in the above-mentioned vertical plane, around a tree 13 carried by a massif 14.
- a counterweight 15 allows balancing of the pivoting column. When the disconnector is in the closed position (which is shown in solid lines in figure 1) this counterweight can be embedded at least partially in the massif 14, which increases the rigidity of the whole.
- Column 21 includes a support structure metallic 21A above which a portion is placed insulator 21B at the end of which is placed a socket current 22 which is for example connected to a cable 23 or to a bar for the connection to the other devices of the station (measuring transformers, etc.).
- a socket current 22 which is for example connected to a cable 23 or to a bar for the connection to the other devices of the station (measuring transformers, etc.).
- the post no longer includes a flexible cable 23, but a busbar rigid, column 21 is the first support of the game bars.
- an electric cable 30, which can consist of several elementary cables (multiple cable), connects the connection member 12 of the swivel column and socket 22.
- the cable substantially describes an arc of rotating circle concavity towards the ground.
- Anti-roll rod 35 connects the top of column 21 to a point in the cable located substantially towards its middle.
- This connecting rod can be made up of a bar, but preferably this connecting rod includes (See Fig. 2), two rigid arms 35A and 35B forming, with a horizontal pivot axis 36, a triangle whose apex is connected to cable 30.
- This axis is made of insulating material, but can be metallic to condition to isolate it from its support.
- anti-roll bar prevents cable 30 from dangerously close, under the effect of forces electrodynamics, cables from neighboring phases.
- a corona element 40 is advantageously placed at the junction between the cable 30 and the anti-roll bar 35.
- the assembly is completed by a setting disconnector earth 45, which can pivot in a parallel vertical plane in the above-mentioned vertical plane and advantageously having the same shaft than the swivel column 11.
- This disconnector earthing includes at its end a connection 46 which can cooperate with connection member 12. It also has a counterweight 48.
- the disconnector is disconnected by pivoting in the direction of the arrow. At the end of pivoting, it comes to occupy a position, shown in dashed lines in Figure 1, where the isolation distances are respected. Cable takes then a hairpin position.
- the disconnector can be earthed by pivoting, in the opposite direction to that of arrow F, of earthing switch 45, including the connection 46 comes to co-operate with a complementary organ to the end of the pivoting column 11.
- the embedding of the counterweight of the earthing switch consolidates its rigidity in the event of a short circuit.
- the fixed column 21 can be column 49 of an intensity transformer 50 equipping the substation.
- disconnector 12 can be rack-in horizontal (Fig. 3) or vertical racking (Fig. 4).
- Horizontal racking can be advantageous in the event of short circuit, because the vibrations only produce friction, without risk of contact separation which would generate sparks, as can happen in the case of vertical racking.
- the item of the invention is of reduced cost, thanks especially the simplicity of the main disconnector.
