Definitions
- Circuit breakers using a said arc chute to "self ⁇ blow" perform a compression with a dielectric gas, for blowing an arc which forms between the arcing contacts during a power cut-off operation, or operation opening of the circuit breaker.
- the compression is generally performed by an operating member, which may be a spring mechanism coupled to a motor, actuating a movable part, such as a piston, in the breaking chamber.
- These circuit breakers also utilize the energy provided by the arc as heat, thereby decreasing the external power consumption compared to conventional gas compression circuit breakers.
- At least one second compression chamber is added relative to the known devices.
- the cooperation between the two compression chambers makes it possible, during a strong power failure, to retain the advantages of a reduced compression stroke produced by the first compression chamber, and during a power failure. low, to achieve this cut without unnecessarily increasing the external energy consumption, mechanical or hydraulic, regardless of the duration of the arc and especially when the arc duration is long.
- the second compression chamber makes it possible to maintain the blowing of the arc, initially produced by the first compression chamber, for the duration of the arc. arc, and that avoiding excessive external energy consumption through the use of the energy provided by the arc during the entire duration of the blowing.
- the power cutoff chamber includes a thermal expansion volume for blowing of the bow and two compression volumes.
- the first compression chamber is rapidly put under overpressure using the displacement of the arcing contacts during a first part only of the total stroke of the moving assembly.
- the compression in the first chamber is therefore performed during a reduced compression stroke, allowing a rapid increase in pressure, and involving blowing performance higher than those devices whose compression is performed during the entire displacement stroke.
- the second compression chamber intervenes if necessary to contribute to the end-of-stroke blow-out of the arcing contacts.
- the second compression chamber can communicate with the first compression chamber via at least one valve, for example a one-way valve.
- the current interruption chamber may include at least one piston closing the first compression chamber at a second end.
- the current interruption chamber may also comprise means immobilizing the piston between the opening operation opening position of the circuit breaker and the compression end position of the first chamber. Thus, by remaining stationary between these two positions, the piston reduces the volume of the first compression chamber and thus compresses the dielectric fluid present in the first compression chamber.
- the means immobilizing the piston may comprise at least one housing for receiving a stop, for example a ball, connected to the piston.
- the current cut-off chamber may also comprise means axially displacing the piston with the moving assembly between the compression end position of the first chamber and the end-of-circuit opening position of the circuit breaker.
- the power failure chamber may comprise means for dislodging the stop of the blocking housing between the end position of compression of the first chamber and the end position of opening operation of the circuit breaker.
- the means for dislodging the stop may comprise at least one housing for receiving the stop.
- the current breaking chamber may comprise at least two second coaxial tubular elements forming the second compression chamber.
- the current interruption chamber may include means closing the second compression chamber at a second end.
- the dielectric fluid may be a dielectric gas, for example sulfur hexafluoride (SF 6 ), nitrogen (N 2 ), dry air, carbon dioxide [CO 2 ] or a gaseous mixture.
- the current interruption chamber may comprise means displacing the second arcing contact in a direction opposite to the movement of the moving assembly during the opening operation of the circuit breaker. In this case, it will be a chamber with double movement of contacts.
- FIG. 1A shows a current breaking chamber 1, object of the present invention, according to a first embodiment.
- the interrupting chamber 1 is in the engaged position, that is to say in the position in which the interrupting chamber 1 is at the beginning of a power failure operation, that is to say at the beginning of an opening operation of the circuit breaker.
- the breaking chamber 1 comprises a casing 2 filled with a dielectric fluid 3, here a dielectric gas, under pressure.
- This gas 3 may for example be sulfur hexafluoride (SF 6 ), nitrogen (N 2 ), dry air, carbon dioxide (CO 2 ) or a gaseous mixture.
- the dielectric fluid could also be a plasma.
- the breaking chamber 1 comprises a first tubular element 4 forming a first compression chamber 5.
- This first compression chamber 5 is closed at a first end by a piston 6 and comprises at a second end a nozzle 21.
- the breaking chamber 1 also has first and second contacts 8, 7, movable relative to each other along an axis AA. In this figure, the second arc contact 7 cooperates with the nozzle 21 to close the first compression chamber 5 at its second end.
- the first arcing contact 8 is movable and the second arcing contact 7 is fixed.
- the first arcing contact 8, here integrated in the piston 6, is disposed inside the first compression chamber 5.
- the breaking chamber 1 comprises at least two second tubular elements 11, 12, coaxial with respect to the axis AA.
- the two second tubular elements 11, 12 are part of the piston 6.
- the space between the two second tubular elements 11, 12 forms a second compression chamber 13.
- the volume of the second chamber of 13 is about three times smaller than that of the first compression chamber 5.
- the second compression chamber 13 communicates with the first compression chamber 5, at a first end, with at least one valve 14, here a unidirectional valve.
- the filling valve 15 is used after the circuit breaker opening operation so that gas 3 can enter the second compression chamber 13 when the interrupting chamber 1 returns to the engaged position.
- the interrupting chamber 1 also comprises permanent contacts 17, 18 circulating the current when the interrupting chamber 1 is in the engaged position. Like the arcing contacts 7, 8, the permanent contacts 17, 18 are axially movable relative to each other along the axis AA. In the three embodiments described, only the contact 18, forming part of the first tubular element 4, is movable.
- FIG. 1B shows the breaking chamber 1 according to the first embodiment in the compression end position of the first compression chamber 5.
- all the elements of the moving assembly 10 except the piston 6 and the third tubular element 20 have been moved along the axis AA by means of maneuver, not shown, connected to a second end of the tube 30.
- the transition from the starting position of operation of circuit breaker opening at the compression end position of the first compression chamber 5 is called the first part of the circuit breaker opening operation or the power failure operation.
- the displacement of the first tubular element 4 reduces the volume of the first compression chamber 5 because the piston 6 remains stationary, thus increasing the pressure inside the first chamber 5.
- First means immobilize the piston 6 during this first part of the opening circuit breaker operation.
- these first means are at least one fixed housing 27 intended to receive at least one stop 25 connected to the piston 6 via the third tubular element 20.
- the abutment 25 is a ball inserted in a wall of the third tubular element 20.
- the rod 9, driven by the tube 30, moves in a groove 19 formed in the third tubular element 20, thereby leaving the third tubular element 20 and the piston 6 stationary.
- the axial displacement stroke achieved during this first part of the circuit-breaker opening operation represents between about one-third and one-half. the stroke of the total axial displacement during a breaker opening operation.
- the permanent contacts 17, 18 are no longer in contact with each other, unlike the arcing contacts 7, 8 which are always in contact with each other. Therefore, in the compression end position of the first compression chamber 5, the current passes only through the arcing contacts 7, 8. The arcing contacts 7, 8 therefore remain in contact during the entire compression phase. of the first chamber 5.
- second means make it possible to make the piston 6 movable.
- these second means comprise at least one housing 31 made in the tube 30, for exiting the ball 25 from the housing 27 and thus no longer blocking the movement of the third tubular element 20 and the piston 6.
- the blowing performed by the first compression chamber 5 is sufficient to extinguish the arc.
- the discharge valve 16 makes it possible to evacuate any positive pressure created in the second compression chamber 13 during the circuit breaker opening operation.
- the duration of the arc is long, and the value of the current is low, that is to say less than about 60% of the default value, the energy brought by the arc is insufficient. so that the blowing created by the first compression chamber 5 extinguishes the arc.
- the arc is therefore always present after the decompression of the gas present in the first chamber 5.
- the pressure in the first compression chamber 5 is then lower than that in the second compression chamber 13, which causes the opening of the valve 14. Gas is then blown from the second compression chamber 13, and this continuous blowing until the moving assembly 10 reaches the end of stroke or the arc goes out.
- FIG. 2A represents a current breaking chamber 1 according to the invention according to a second embodiment.
- the interrupting chamber 1 is in the starting position of the circuit breaker opening operation, or of the circuit breaker opening operation.
- the first compression chamber 5 here comprises two volumes 5a, 5b.
- the first volume 5a is the one in which compression is performed by the piston 6 during the first part of the circuit breaker opening operation.
- the two volumes 5a, 5b are separated by a wall 22 provided with at least one valve unidirectional 23 opening only when the pressure in the first volume 5a is greater than that of the volume 5b.
- the pressure increases similarly in the second volume 5b.
- FIG. 4A shows a breaking chamber 1 according to a fourth embodiment.
- the two arcing contacts of this fourth embodiment are movable.
- the first arcing contact 8 is integrated with the piston 6.
- the first arcing contact 8 is movable between the compression end position of the first chamber 5 and the end position of circuit breaker opening operation.
- FIG. 4B shows the current breaking chamber 1 in the compression end position of the first chamber 5.
- the piston 6 has remained stationary.
- the first tubular element 4 has moved axially along the axis AA, causing compression of the dielectric gas in the first compression chamber.
- the present invention is particularly adapted to operate under high voltage, for example when the voltage is greater than 245 kV.
