Definitions
- the invention relates to a high voltage hybrid circuit breaker comprising in each pole: a main circuit with main contacts for the passage of nominal current, an arc circuit having a gas circuit breaker connected in series with a switch supporting the DU / dt of the transient recovery voltage, means for actuating the movable main contact, and movable arcing contacts, between open and closed positions, current supply terminals, - a casing filled with an insulating gas with high dielectric strength, said casing being subdivided into a first compartment confined by an insulator for housing the main contacts of the main circuit, and of the gas circuit breaker, and a second adjacent compartment containing the switch, said second compartment being formed by a metallic envelope of conductive material.
- the cut-off device relates to a gas switch SF6 contained in an insulating envelope, and connected in series with a vacuum switch, which is arranged in a metal envelope.
- Each switch has its own actuation means, those associated with the vacuum switch, intervening only when the short-circuit current exceeds a predetermined threshold.
- the vacuum interrupter is formed by several vacuum bulbs connected in parallel. The operating status of these bulbs cannot be easily checked by the user.
- the gas circuit breaker and vacuum interrupter assembly is housed in a common enclosure, and two control mechanisms are necessary to actuate the arcing contacts.
- Such a device is complicated and expensive.
- the object of the invention is to provide a high-voltage hybrid circuit breaker of simple and inexpensive design.
- the circuit breaker according to the invention is characterized in that the movable arcing contact of the gas circuit breaker is actuated with the movable main contact by a main control rod connected to a common mechanism, the movement of movement of the movable arcing contact of the switch being derived from the translational movement of the main rod by means of an intermediate transmission lever housed in the second compartment.
- the switch Since the switch does not support the mains voltage, it is possible to insert it in a compartment without an insulator.
- the switch control means are housed in this compartment.
- the switch can be constituted either by a vacuum interrupter, or by a rotating arc cut-out device, or by a semiconductor power circuit.
- the gas circuit breaker can be of the self-expanding or self-blowing gas piston type.
- FIG. 1 is a schematic sectional view of the hybrid circuit breaker according to the invention.
- FIG. 2 shows the electrical diagram of the hybrid circuit breaker
- FIGS. 3A to 3E show the diagrams of current and voltage as a function of time.
- a high-voltage hybrid circuit breaker pole 10 in particular greater than 100 kV, comprises a multiple contact system housed in a first compartment 12 and a second compartment 14 adjacent, the assembly being carried by a support insulator 16 hollow.
- the first compartment 12 contains a main circuit 18 supplied by a pair of connection terminals 20, 22, and comprising a movable main contact 24 in the form of a bridge cooperating with fixed main contacts 26, 28 in electrical connection respectively with the terminals 20, 22.
- the main circuit 18 coaxially surrounds a gas circuit breaker 30 comprising a first metal chamber 31 containing a first fixed arcing contact 32, and a second movable arcing contact 34 tubular arranged at the end of a conductive tube 36 .
- the other end of the tube 36 is provided with a drive pin 38 cooperating with a transmission yoke 40 to move the second movable arcing contact 34 in translation between a closed position and an open position.
- the interior of the chamber 31 communicates with the remaining volume of the first compartment 12 through the tube 36 and radial openings 42 of the yoke 40.
- a spring 44 interposed between the yoke 40 and the lug 38 of the tube 36, urges the second arcing contact 34 in engagement against the first arcing contact 32.
- the first compartment 12 is delimited by an insulator 46 made of insulating material, in particular ceramic, while the second compartment 14 is arranged in a sealed envelope 48 made of conductive metallic material, interposed between the open bottom 50 of the insulator 46, and a end piece 52 of the support insulator 16.
- An insulating gas with high dielectric strength, in particular sulfur hexafluoride, is located inside the two compartments 12, 14.
- a vacuum interrupter 54 is arranged inside the second compartment 14, and comprises a second sealed chamber 56 which is in depression with respect to the gas pressure.
- the vacuum interrupter 54 contains a third fixed arcing contact 58 carried by a stud 60 subject to the metal casing 48, and a fourth movable arcing contact 62 actuated in translation by a control rod 64 between a position of closing and an open position.
- the sliding rod 64 passes through the insulating front wall 66 of the chamber 56 with the interposition of a sealing bellows 68, and is on the other hand in mechanical connection with a rod 70 cooperating with a double lever 72 for driving.
- the double lever 72 is mounted with limited pivoting on an axis 74, and comprises a first arm 72a having a first oblong opening 76 in which a crankpin 78 of the rod moves.
- the second arm 72b has a second oblong opening 80 in which is engaged a drive pin 82 integral with the main control rod 84.
- the pivot axis 74 of the double lever 72 is fixed to the metallic casing 48, and the straight rod 70 extends perpendicularly to the main rod 84 of the circuit breaker 10, which is connected to the control mechanism (not shown) the hollow support insulator 16.
- the rod 64 for controlling the vacuum interrupter 54 is electrically conductive, and is electrically connected to the yoke 40 by a connecting braid 86.
- the yoke 40 is electrically connected to the contact 34 by a sliding contact, for example pliers (not shown).
- the casing 48 is electrically connected to the main contact 28 fixed in connection with the terminal 22.
- FIG. 2 shows the unipolar electrical diagram of the hybrid circuit breaker 10.
- the main circuit 18 in which the nominal current IP flows is electrically connected in parallel to the terminals of the gas circuit breaker 30 and of the vacuum bulb 54, including the contacts of movable arcs 34, 62 are connected in series by the braid 86.
- a varistor 88 shown in dotted lines in FIG. 2 can be connected to the terminals of the vacuum interrupter 54.
- FIG. 3A shows the shape of the total current IT at time t1
- FIG. 3C shows the appearance of the current ID in the arcing circuit.
- the yoke 40 drives the lug 38 of the tube 36, and the descent of the axis 82 simultaneously causes the double lever 72 to pivot in the clockwise direction, and the translation of the rod 70 to the left. This results in the almost simultaneous opening of the two pairs of arcing contacts 32, 34; 58, 62 of the gas circuit breaker 30, and the vacuum interrupter 54
- FIGS. 3D and 3E respectively representing the arcing voltages at the terminals of the vacuum bulb 54, and of the gas circuit breaker 30, it is noted that the vacuum bulb 54 supports the transient recovery voltage between times t2 and t3.
- the gas circuit breaker 30 has not yet deionized at time t3. As the vacuum circuit breaker 54 cannot withstand the network voltage, it resets at time t3. We then wait for the next current to go to zero, which occurs at time t4. As before, the vacuum interrupter supports the transient recovery voltage, between times t4 and t5. This time, the gas circuit breaker
- the dielectric strength of the hybrid circuit breaker 10 is ensured by the gas circuit breaker 30, which must imperatively be placed in the first compartment 12 of the insulator 46.
- the vacuum interrupter 54 is unable to hold the network voltage, and can therefore be placed in the second compartment 14 of the metallic envelope 48.
- the double lever 72 and the rod 70 for controlling the vacuum bulb 54 are also placed in the second compartment 14. It is clear that the vacuum bulb can be replaced by another switch supporting the DU / dt of the transient recovery voltage, by example a rotary arc switch, or a power semiconductor.
- the gas circuit breaker can be a self-expanding or piston-type circuit breaker supporting high voltages, for example greater than 100 kV.
- the rods 84 and 70 can extend in any directions.
