Definitions
- the cut-off device relates to a SF6 gas switch contained in an insulating envelope, and connected in series with a vacuum switch, which is arranged in an enclosure metallic.
- Each switch has its own actuation means, those associated with the vacuum switch, intervening only when the current short circuit exceeds a predetermined threshold.
- the vacuum switch is formed by several vacuum bulbs connected in parallel. The operating state of these bulbs cannot be easily checked by the user.
- the gas circuit breaker and light bulb assembly vacuum is housed in a common envelope, and two mechanisms are required to activate the arcing contacts.
- Such device is complicated and expensive.
- the object of the invention is to provide a hybrid circuit breaker with high simple and cheap design tension.
- the circuit breaker according to the invention is characterized in that the arcing contact gas circuit breaker is operated with the main mobile 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 thanks to a lever transmission intermediary 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 bulb or by a arc breaking device, either by a semiconductor circuit power.
- the gas circuit breaker can be of the self-expanding or self-blowing type by gas piston.
- a high voltage hybrid circuit breaker pole 10 in particular greater than 100 kV, has a multiple contact system housed in a first compartment 12 and a second compartment 14 adjacent, the assembly being carried by a hollow support insulator 16.
- the first compartment 12 contains a main circuit 18 powered by a pair of connection terminals 20, 22, and comprising a contact main mobile 24 in the form of a bridge cooperating with contacts main fixed 26, 28 in electrical connection respectively with the bomes 20, 22.
- the main circuit 18 coaxially surrounds a gas circuit breaker 30 comprising a first metallic 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 has a lug 38 for driving cooperating with a yoke transmission 40 to move the second arcing contact in translation movable 34 between a closed position and an open position.
- 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 pin 38 of the tube 36, requests the second arc contact 34 in engagement against the first arcing contact 32.
- the first compartment 12 is delimited by an insulator 46 made of material insulator, in particular ceramic, while the second compartment 14 is arranged in a sealed envelope 48 of metallic material conductor, inserted between the open bottom 50 of the insulator 46, and a ferrule 52 of the support insulator 16.
- An insulating gas with high dielectric strength, including sulfur hexafluoride, is found inside the two compartments 12, 14.
- a vacuum interrupter 54 is arranged inside the second compartment 14, and comprises a second sealed chamber 56 located at vacuum in relation to gas pressure.
- the vacuum interrupter 54 contains a third fixed arcing contact 58 carried by a stud 60 secured to the casing 48 metallic, and a fourth movable arcing contact 62 actuated in translation by a control rod 64 between a closed position and an open position.
- the sliding rod 64 passes through the front wall 66 insulating chamber 56 with interposition of a sealing bellows 68, and is on the other hand in mechanical connection with a rod 70 cooperating with a double drive lever 72.
- the double lever 72 is mounted with limited pivoting on an axis 74, and includes 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 shaft 82 secured to the main control rod 84.
- the pivot axis 74 of the double lever 72 is fixed to the casing 48 metallic, and the straight rod 70 extends perpendicular to the rod main 84 of circuit breaker 10, which is connected to the control (not shown) by crossing the hollow support insulator 16.
- the control rod 64 of the vacuum interrupter 54 is conductive of electricity, and is electrically connected to the yoke 40 by a braid of link 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 at connection with terminal 22.
- Figure 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 interrupter 54, the movable arcing contacts 34, 62 of which are connected in series by braid 86.
- a varistor 88 shown in dotted lines in FIG. 2 can be connected across the vacuum interrupter 54.
- the main contacts 24, 26, 28, and all of the arcing contacts 32, 34; 58, 62 are slots.
- FIG. 3B shows the interruption of the main current IP at time t1
- the FIG. 3C shows the appearance of the current ID in the arc circuit.
- the yoke 40 drives the lug 38 of the tube 36, and the descent of the axis 82 simultaneously causes the pivoting of the double lever 72 in a clockwise direction, and the translation from the rod 70 to the left. This results in the almost simultaneous opening of two pairs of arcing contacts 32, 34; 58, 62 of the gas circuit breaker 30, and the vacuum interrupter 54
- the dielectric strength of the hybrid circuit breaker 10 is ensured by the gas circuit breaker 30, which must be placed in the first compartment 12 of insulator 46.
- the vacuum interrupter 54 is unable to hold the mains voltage, and can therefore be placed in the second compartment 14 of the envelope 48 metallic.
- the double lever 72 and the rod 70 for controlling the bulb vacuum 54 are also placed in the second compartment 14. It is clear that the vacuum interrupter can be replaced by another switch supporting the DU / dt of the transient recovery voltage well, by example a rotary arc switch, or a semiconductor of power.
- the gas circuit breaker can be a self-expanding circuit breaker or a ramming with high voltages, for example greater than 100 kV ..
- rods 84 and 70 can extend in directions any.
