Definitions
- the invention relates to the field of medium, high or very high voltage circuit breakers. It relates more particularly to the problem of the Joule effect heating of the shut-off chamber in the closed position, as well as the management of the exhaust of the hot gases resulting from the blowing of the electric arc during an opening operation of the breaker.
- circuit breaker designs such as that described in DE 10 2011 083593.
- Such a circuit breaker incorporates an exhaust hood pierced with openings for the evacuation of gases.
- the circuit breaker In the closed position, the circuit breaker is traversed by a current which, by joule effect, releases energy in the form of heat at the electrical interfaces, in the interrupting chamber.
- the openings in the exhaust hood must therefore be large enough to evacuate the hot gases to the gas volume defined by the outer casing of the tank and not degrade these electrical interfaces.
- the hot gases from the blowing of the electric arc pass through these openings to get out of the breaking chamber to the outer casing of the circuit breaker.
- This outer envelope is then subject to risks of aggression by the hot gases and the microparticles entrained by these gases.
- an electrical insulation fault may form through these hot gases and cause a dielectric breakdown between part of the electrically charged chamber (at the non-zero potential ), and the metal outer shell of the circuit breaker at zero potential.
- the openings through the exhaust hood must therefore not be too large, in order to reduce the flow of hot gas to the outer casing.
- the subject of the invention is a medium, high or very high voltage current circuit breaker, comprising at least one breaking chamber and an outer envelope defining a space in which the breaking chamber is arranged, this one comprising:
- first and second sets being movable so as to allow operations of closing and opening the circuit breaker; an electric arc blowing nozzle;
- an exhaust hood located in the space and comprising a bottom and a lateral envelope internally defining a gas circulation chamber located at least partly downstream of the blast nozzle, the exhaust hood comprising at least an opening for evacuation of the gas.
- the circuit breaker comprises means for closing said opening, said shut-off means being movable between a closed position in which they prohibit the passage of gas through the opening, and a withdrawal position in which they allow this passage, the circuit breaker being configured so that in its closed position, said closure means occupy their retracted position, and so that the transition from the withdrawal position to the position of closure occurs during a circuit breaker opening operation.
- the invention firstly has the advantage of reducing the temperature in the interrupting chamber during normal operation, when the circuit breaker is in the closed position. Indeed, the opening released by the sealing means allows natural convection to the interior space defined by the envelope. Also, the heating effects of the breaking chamber, due to the passage of the current in the closed position, can be largely attenuated.
- the invention provides for closing the opening during an opening operation of the circuit breaker. Consequently, as soon as this opening is closed, the hot gases resulting from the blowing of the arc remain confined in the chamber, which limits the risks aggression of the outer casing of the circuit breaker by these hot gases and the microparticles they cause, or the risk of dielectric ignition between the breaker circuit breaker chamber and the outer casing.
- the invention also has at least one of the following optional features, taken alone or in combination.
- the circuit breaker is configured so that the shutter position is maintained until the end of the opening operation of the circuit breaker, and the transition from the closed position to the retracted position takes place during the next operation of closing the circuit breaker.
- the shutter position is maintained until the end of the opening operation of the circuit breaker, and the risks of aggression of the outer casing of the circuit breaker are further reduced.
- the withdrawal position it can be performed at the beginning or end of the closing operation of the circuit breaker, or at any time between these two moments.
- the transition from the closed position to the retracted position may be abrupt or gradual, depending on the chosen design.
- the circuit breaker is configured so that the transition from the retracted position to the closed position takes place after the initiation of the opening operation of the circuit breaker.
- This makes it possible to evacuate all or part of the cold gas under high pressure present in the interrupting chamber just after the initiation of an opening operation of the circuit breaker. Thanks to the evacuation of the cold front edge, the pressure in the chamber is thus reduced, and the mechanical forces required for the displacement of the electrical contacts are advantageously reduced.
- this preliminary evacuation allows, during the subsequent operation of opening, to increase the pressure differential between the heart of the chamber and the emptied exhaust of its high pressure cold flow. This advantageously results in a better flow of gas between the nozzle and the gas flow chamber, or a better blowing of the electric arc, and therefore an increased capacity of cut-off for the circuit breaker.
- the circuit breaker comprises first drive means of the first and second sets of electrical contacts, as well as second drive means ensuring the passage of the closure means from their retracted position to their closed position, and said second drive means comprise at least one moving part of the circuit breaker, set in motion during the opening operation of the latter.
- the setting in motion of the parts for the closing / opening of the circuit breaker is advantageously used to move the shutter means of the opening between its two positions.
- the first and second drive means may have one or more parts in common.
- the electrical contacts and / or the integral parts thereof, such as the blowing nozzle could be an integral part of these second drive means. This advantageously makes it possible to obtain a good synchronization between the opening / closing operations and the operations of maneuvering the closure means.
- separate means could be provided for driving the contacts and for driving the means for closing off the opening.
- a non-linear kinematics can be provided, for example so as to open the circuit breaker and close the closure means at different times.
- the closure means comprise a sealing ring mounted coaxially with the lateral casing of the exhaust cowl, and movable axially relative thereto.
- this ring closes a single annular opening, or several openings angularly distributed around the axis of the lateral casing of the exhaust hood.
- the shutter means comprise a shutter covering one or more openings in the closed position, the shutter being rotatably mounted relative to the exhaust hood.
- This shutter can indifferently be mounted on the side casing of the exhaust hood, or on its bottom.
- the closure means comprise at least one non-return valve, capable of moving from its withdrawal position to its closed position under the effect of the gas pressure in the gas circulation chamber, the circuit breaker being moreover configured in such a way that after reaching the closed position of the valve, the valve is held by additional holding means, independent of the gas pressure; exerting on the flap.
- additional means are preferably mechanical means for holding the valve in position shutter, intended to be released during the next operation of closing the circuit breaker, still mechanically.
- other technologies can be envisaged, such as electromagnetic holding means.
- the valve can be provided on the side casing of the exhaust hood, or on its bottom.
- interrupting chamber is preferably of the type with double movement of the contacts, but could be a simple contact movement, without departing from the scope of the invention.
- the subject of the invention is a method of controlling a medium, high or very high voltage current circuit breaker, as described above, the method comprising the steps of:
- FIGS. 1a and 1b show schematic views in longitudinal section of a high-voltage circuit breaker according to a first preferred embodiment of the invention, with the circuit-breaker respectively in a closed position and in a busy position during an opening operation of this circuit breaker;

- the circuit breaker 10 comprises a breaking chamber 12.
- the interrupting chamber 12 is arranged inside an envelope 14.
- the breaking chamber 12 is thus housed in a space 13 defined internally by the outer envelope 14. This space 13 is usually filled with an insulating gas, for example SF6 type.
- the chamber 12 comprises a first set of electrical contacts 18a, 20a and a second set of electrical contacts 18b, 20b. More specifically, the first set comprises a first permanent contact 20a cooperating with a second permanent contact 20b of the second set, when the circuit breaker occupies a closed position as shown in FIG. In addition, the first assembly comprises a first arcing contact 18a, cooperating with a second arcing contact 18b of the second set, when the circuit breaker is in its closed position. The first arcing contact 18a passes through a blow nozzle 19, made in a conventional manner.
- the invention is not limited to this embodiment.
- the invention can in particular be applied to double movement circuit breakers.
- any design deemed appropriate by those skilled in the art can be implemented, such as that described in document FR 2 976 085.
- the two sets are thus mobile to sliding along the main axis A of the breaking chamber 12, in opposite directions.
- the second arcing contact 18b is surrounded by two volumes 21 and 21 'separated axially from one another by a wall, and allowing the extinction by blowing the electric arc, to cut the current.
- the blowing nozzle 19 makes it possible to channel the flow of gas during this blowing.
- the chamber 31 is thus arranged at least partly downstream of the nozzle 19, the term "downstream" being considered here in an axial main direction of gas flow in the chamber 12 at the outlet of the nozzle 19.
- the breaking chamber 12 thus comprises the exhaust cowl 40 forming the outer wall of the exhaust volume 31.
- the exhaust cowl 40 comprises a bottom 40a as well as a lateral envelope 40b together defining, internally, the gas flow chamber 31.
- lateral envelope 40b comprises an annular opening 50 for evacuation of gas to the space 13 defined by the tank 14.
- This opening 50 s' extends laterally over substantially 360 ° about the axis A, and extends axially over a large length of the cover, for example over 20 to 40% of the total length of the cover.
- the opening 50 is arranged near an upstream end of the cover 40, but can of course be arranged differently on this cover.
- the invention is applicable regardless of the configuration inside the chamber 31, and not limited to the particular embodiments described with reference to Figures 2 and following.
- the hood 40 is equipped with means 52 for closing off the annular opening 50. These shut-off means are movable between a closed position shown in FIG. 1b in which they prohibit the passage of gas to through the opening 50, and a withdrawal position shown in Figure la in which they allow this passage.
- the circuit breaker is configured so that in its closed position, the closure means 52 occupy their retracted position, and so that the transition from the retracted position to the closed position s operates during an opening operation of the circuit breaker. This principle specific to the invention will now be described with reference to FIGS. 2 and 3, in which the circuit breaker adopts a particular, non-limiting configuration of the invention.
- the two assemblies 18a, 20a, 18b, 20b are simultaneously driven by a control mechanism comprising an operating rod 22 which is centered on the axis A of the interrupting chamber 12, and which is movable axially sliding in the interrupting chamber.
- the operating rod 22 drives a drive member 24, which consists here of a return lever which is pivotally mounted on a fixed part of the breaking chamber 12, about an axis 25 perpendicular to the plane of FIG. It will be understood that the invention is not limited to this embodiment of the drive member 24, which may also consist of a cam, a roller or a rack, which is made to cause the contacts.
- the lever 24 is connected to the operating rod
- the sets of electrical contacts are connected to the return lever 24 so that the first contacts 18a, 20a and the second contacts 18b, 20b move simultaneously in opposite directions during the rotation of the lever 24.
- Displacements in opposite directions of the contacts have the main advantage of obtaining a high relative speed of displacement, while maintaining a lower speed of the contacts relative to the fixed parts of the interrupting chamber 12.
- the lever 24 consists of an oblong element whose long length is mainly transversal to the main axis A of the breaking chamber 12.
- the lever 24 is pivotally mounted at its center in the breaking chamber 12, and its ends are connected to the electrical contacts via connecting rods 26, possibly elastic.
- the pivoting member 28 and the lever 24 are arranged in an inner part 30 of the cylindrical gas circulation chamber 31, defined internally by a tubular wall 33 centered on the axis A.
- the inner portion 30 of the cylindrical gas circulation chamber 31 is delimited at its upstream axial end by the nozzle 19, that is to say beyond a contact support 34 arranged substantially orthogonal to the axis A.
- the first set of contacts 18a, 20a is slidably mounted relative to the wall tubular 33 along the axis A.
- the movable support 34 is arranged inside the same wall 33 forming a tube in the exhaust chamber 31.
- the chamber 31 forms a blowing chamber 36 initiated from the nozzle 19. Also, the blowing chamber 36 extends axially, from upstream to downstream, between the nozzle 19 and the support 34 of the first set of electrical contacts.
- the support 34 which varies the geometry of the blowing chamber 36 when it moves axially during the opening and closing operations of the circuit breaker, allows fluid communication on either side of the support. Suitable orifices are thus made through the support 34, for the passage of gases.
- the breaking chamber 12 comprises the exhaust hood 40, the lateral envelope 40b of which surrounds the tubular wall 33.
- the bottom 40a of the gas circulation chamber 31 is located at the opposite of the support 34. It extends laterally beyond the wall 33, to join the lateral envelope 40b.
- annular space 42 for exhausting gas is then defined between the lateral envelope 40b and the tubular wall 33, this space 42 forming an integral part of the gas circulation chamber 31, constituting the outer part thereof.
- the gases circulating in the inner part 30 of the chamber 31 can enter this space 42, by means of holes 44 made on the wall 33.
- the cover 40 remains open. and defines an exhaust opening 46 of annular shape, of small section.
- This annular opening 46 delimited internally by the wall 33, is oriented axially in a direction opposite to that of the bottom of the circuit breaker.
- a part 48 shown in the following figures
- forming a baffle makes it possible to reorient the flow of gas axially towards the bottom of the circuit breaker, after its exit through the exhaust opening 46.
- the gases enter the space 13 delimited by the tank 14, outside the breaking chamber 12.
- the bottom 15 of the tank is connected to the bottom 40a while being at a distance from it, the mechanical connection being preferably carried out by means of an insulating support (not shown) arranged between the two elements 40a, 15.
- the lateral envelope 40b of the cover 40 is here equipped with an opening 50 for evacuation of the gas from the annular space 42, towards the space 13 defined by the tank 14.
- the sealing means of the opening 52 are here displaceable between a withdrawal position shown in Figure 2 in which the gases can flow through the opening 50 towards the space 13, and a closed position shown in Figure 3, prohibiting the passage of these gases towards the same space.
- the closure means 52 take the form of a closure ring centered on the axis A, and movable relative to the wall 33 along the same axis.
- the ring 52 is arranged inside the tubular wall 33, but could be placed externally, without departing from the scope of the invention.
- Certain elements of the first means for driving the electrical contacts, in particular the pivoting member 28 and the lever 24, are also an integral part of the second means.
- a mechanical connection member 54 is placed between one end of the lever 24 and the ring 52. Also, when the lever 24 and the member 28 are set in motion to cause the opening or closing of the circuit breaker, they simultaneously cause the displacement of the ring 52 from its retracted position to its closed position, or vice versa.
- the lever 24 in motion causes the displacement of the sealing ring 52 towards its closed position shown in FIG. hot gases from the blowing of the electric arc passing through the chamber 31, circulating successively by the blowing chamber 36, the inner portion 30 of the chamber 31, the holes 44, the annular exhaust space 42 and then the annular opening 46. Leaving the chamber 31 through the opening 46, the hot gases then reach the large space 13.
- the risk of aggression of the tank 14, by these gases and the microparticles they cause is limited, as well as the risk of dielectric priming.
- the opening 50 is kept closed during the entire opening operation of the circuit breaker, and is released only during the operation. following closing, still under the action of the lever 24.
- openings 50 of reduced section are made through the lateral casing 40b of the exhaust hood 40.
- These openings are grouped, and cooperate with a shutter 52 rotated on the same axis 25 as that of the pivoting member 28 for rotating the lever 24 or the like.
- the shutter 52 covers the openings as it has been shown in Figure 5a, while in the retracted position shown in Figure 5b, the shutter 52 is offset from the openings 50, allowing the passage of gases.
- the shutter takes here for example the form of a half-disc cooperating with a flattened portion of the envelope 40b on which are formed the openings 50.
- the shutter 52 is arranged externally on the envelope 40b, but could be arranged internally, without departing from the scope of the invention.
- Another group of openings 50 could be made at the opposite end of the member 28, still being associated with a shutter controlled by the same member 28, used for the implementation of the opening operations and closing circuit breaker.
- openings 50 are made through the bottom 40a of the exhaust hood 40. These openings 50 open here into the annular space 42, forming the outer part of the gas circulation chamber 31. In the alternative embodiment shown in FIG. 7, these openings are closer to the axis A and open into the inner part 30 of the chamber 31.
- closure means 52 take the form of a non-return valve associated with each opening 50.
- the valves 52 take the conventional form of spring valves, the particular operation of which will be presented below.
- each valve 52 In neutral position of rest, the spring of each valve 52 leads the latter to release its associated opening, so that the valve adopts the position of withdrawal allowing the communication between the chamber 31 and the space 13, via the associated opening 50.
- This removal position as shown for the valve 52 at the bottom of Figure 6, is adopted when the circuit breaker is in the closed position.
- the cold pressure front discussed above travels downstream towards the bottom 40a and, by its high pressure, presses each valve which then moves into its closed position .
- This position is represented on the valve 52 of the top of FIG. 6. Since the pressure of the gas decreases after the passage of this cold front, the circuit breaker is equipped with additional mechanical holding means 56, making it possible to hold each valve 52 in its position. shutter. Also, this closed position is maintained even though the pressure inside the chamber 31 would not generate sufficient force on these same valves to keep them closed.
- additional means whose design can take any form deemed appropriate by those skilled in the art, therefore allows to act on the position of the valves 52 regardless of the pressure exerted on them.
- valves 52 can be kept closed, and the risk of aggression of the vessel by the hot gases are limited, as well as the risks of dielectric firing.
- the additional means 56 are preferably designed to mechanically release the valves 52 during the next operation of closing the circuit breaker, for example during the initiation thereof.
