    专利说明:

    [0001] The present invention generally relates to a circuit breaker comprising a pyrotechnic actuator, intended to be mounted on a motor vehicle, and in particular on an electric vehicle. In such electric vehicles, it is necessary to be able to cut the 5 electrical lines connecting the electrical energy storage devices (batteries, super capacitors, ...) to the rest of the vehicle, to put it safe if an accident occurs. for example. Because of the powers involved, and the characteristics of the electrical circuits, electric arcs will occur during the break and call into question the break of the circuit or its integrity if these arcs are not mastered. It is known in the prior art circuit breakers such as that disclosed in EP0359467A2, and which propose specific arrangements to extinguish the arcs. In return, this system has the disadvantage of being bulky if it is used to cut electrical circuits with voltages and / or high currents. An object of the present invention is to meet the drawbacks of the documents of the prior art mentioned above and in particular, first of all, to propose a compact circuit breaker and which provides a fast break even if an electric arc is form. For this, a first aspect of the invention relates to a circuit breaker comprising: at least one electrical conductor arranged to be connected to an electrical circuit, a housing, a matrix, a punch arranged movable relative to the housing; to go from a first position to a second position, a pyrotechnic actuator arranged to move said punch from the first position to the second position, when it is fired, the punch and the die being arranged to forming a punch-die assembly arranged to, when the punch passes from the first position to the second position: - cutting said at least one electrical conductor into at least two distinct parts, and - generating the establishment, between the punch and the matrix, at least 10 an electric arc between the at least two separate parts, when the circuit breaker is connected to a live electrical circuit, characterized in that: - the assembly the punch-die, when the punch is in the second position, is arranged to leave at least one passage between the at least two distinct parts, said at least one passage being arranged to guide said at least one electric arc between the parts distinct, and in that - the punch-die assembly comprises at least one material arranged to be removed by ablation by said at least one electric arc, to generate gas capable of increasing a voltage of said at least one electric arc. The circuit breaker according to the present invention makes it possible to control the formation of electric arcs created when the punch cuts the electrical conductor into two distinct parts. Indeed, when the punch is in the second position, a passage is formed by the punch-die assembly, so that the electric arc or arcs are guided by the passage, which guarantees their location and limits the risks of damage the rest of the circuit breaker. In addition, the circuit's efficiency and cut-off speed are improved by the material arranged to be removed by ablation which makes it possible to increase the arcing voltage once the pyrotechnic actuator has operated, that is, that is, the circuit breaker will be effective even for a high voltage across it, without enlarging the gaps between the separate parts, thereby improving compactness. Indeed, the material arranged to be removed by ablation is sublimated under the action of the intense heat flux of the electric arc, which changes the composition of the electric arc plasma and its conductivity, and allows to increase the electric arc voltage. Such arcs can be created when the circuit breaker is connected to a live electrical circuit, with voltages ranging from 0V to 600V and currents ranging from 0A to 5000A on inductive loads up to 2500pH (micro- Henry) for an intensity of less than 500A and up to 150pH for an intensity of 5000A. The circuit breaker according to the invention makes it possible to cut the current reliably in less than 10ms and even less than 5ms, in a definitive manner, since the circuit breaker, comprising a pyrotechnic actuator, can only be used for Once. Advantageously, the passage may be formed between the punch and the die, or in one of these pieces. Advantageously, one of the punch or die is at least partially made with the material arranged to be removed by ablation. Advantageously, the material arranged to be removed by ablation is POM (polyoxymethylene (or polyformaldehyde)). According to this implementation, the material to be removed by ablation will make it possible to create, during the ablation, a gaseous mixture which increases the voltage of the electric arc because the POM has a ratio of the number of carbon atoms on the number of oxygen atoms very low, close to 1. It is also possible to consider using polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polybutylene terephthalate (PBT), polyethersulfone ( PESU), or polyamide 6-6 (PA6.6). Advantageously, said at least one passage is at least partially delimited by the ablatively removable material. The present implementation increases the effectiveness of the circuit breaker because the arcing ablative material is located in its immediate vicinity, which ensures a rapid increase in the voltage of the electric arc due to Advantageously, said at least one passage is a groove formed in the punch and / or the die. We can consider a groove whose dimensions are as follows: width ranging from 0.1 to 1 millimeter, and depth ranging from 0.1 to 1 millimeter. Such a groove can be obtained directly by molding if the dimensions are compatible with this technology and the injected material, or by resuming machining. Advantageously, when the punch is in the second position, the punch and the die are arranged with a tight fit except for said at least one passage. According to the present implementation, the punch and the die have a tight fit to ensure the irreversibility of the movement of the punch, which prevents on the one hand any backward movement. On the other hand, this tight fit provides a good seal, which forms a natural barrier against the passage of the electric arc elsewhere than in the passage. As a result, the electric arc is forced to pass through the passage which remains free and at which the punch and the die are not in tight fit condition (since there is play). It is conceivable to provide between the punch and the matrix a negative clearance ranging from 0 to 0.3 millimeters. Advantageously: - each of said at least two distinct parts has a cut end separated from one another when the punch is in the second position, - said at least one passage is arranged on the shortest path between the cut ends. The passage being formed on the shortest path between the cut ends, the path of the electric arc will be favored, since it is the path that will require the least energy. Advantageously, the circuit breaker comprises an insert which comprises a guiding portion for the punch, and a reinforcing portion for the die. The insert according to the present implementation is a single piece 30 continuous and monobloc which combines the guiding function for the punch and the -5 reinforcement function for the matrix. The assembly can be done by overmolding on the electrical conductor, which minimizes the risk of misalignment between the punch (guided by the guide portion of the insert) and the matrix (reinforced therefore positioned by the reinforcing portion).
    [0002] Advantageously, the insert is made of polyamide 6-6 (PA6.6), loaded with 30% glass fibers. Advantageously, the insert comprises a face arranged to enter into mechanical abutment with the punch and thus define the second position. Advantageously, the matrix is arranged to be elastically deformable so as to guarantee a surface contact with the exception of said at least one passage with the punch when the punch is in the second position. The path of the electric arc will be all the more difficult elsewhere than in the passage, with a surface contact between the punch and the die.
    [0003] Advantageously, the matrix comprises a recess arranged between itself and the reinforcing portion. This recess allows the matrix to move and / or deform under the action of the punch, to self align with the latter and ensure a good seal between the punch and the die. It can be envisaged that the recess is between 0 and 2 millimeters, more particularly between 0 and 1 millimeter, and very advantageously between 0 and 0.5 millimeters. Advantageously, the matrix comprises with the reinforcing portion a connection point separating two recesses between the matrix and the reinforcing portion. This implementation allows pivoting of a wall of the matrix around the connection point, not a crash. This connection point can be placed vis-à-vis the passage so as to control the section of the passage available for the establishment of the electric arc. Advantageously, the punch in the second position and the housing form at least one breaking chamber and said at least one cut-off chamber comprises a vent towards the outside of the circuit breaker and sealed, arranged to break beyond a predetermined pressure difference between said at least one interrupting chamber and the outside of the circuit breaker. The present implementation proposes a safety valve in the interrupting chamber calibrated to open at a given pressure. This makes it possible to evacuate an excess of pressure without calling into question the integrity of the device in case of operation beyond the nominal conditions while guaranteeing a sealed system under the nominal conditions. Advantageously, the punch has two cutting edges, so as to cut said at least one electrical conductor into three distinct parts. This implementation will force the creation of two electric arcs in series from each other, which increases the cutoff characteristics of the circuit breaker. Advantageously, the circuit breaker comprises an insert which comprises a guiding portion for the punch, and a reinforcing portion for the die. The insert according to the present implementation is a single piece continuous and monobloc which combines the guiding function for the punch and the reinforcing function for the matrix. The assembly can be done by overmolding on the electrical conductor, which minimizes the risk of misalignment between the punch (guided by the guide portion of the insert) and the matrix (reinforced therefore positioned by the reinforcing portion). Advantageously, the matrix comprises a counter form arranged between the two cutting edges, so as to define two breaking chambers, when the punch is in the second position.
    [0004] Advantageously, the punch is arranged movable along a predetermined axis of translation and the die is arranged symmetrically with respect to the axis of translation of the punch. The cutting forces are symmetrically distributed, which limits the risk of jamming. Advantageously, the punch comprises at least one cutting edge 30 in bevel, to cut said at least one electrical conductor gradually during its passage from the first to the second position. The cutting force with this implementation is less than that required by a straight cut of the electrical conductor, where the entire section is sheared at one time. The pressures to be implemented are then reduced and the size of the circuit breaker also, with this progressive cut bevel. Advantageously, the beveled cutting edge has an angle of between 90 ° (excluded terminal) and 75 ° relative to the direction of movement of the punch.
    [0005] Advantageously, the punch comprises a cutting edge in the shape of a "V" with the tip of the "V" positioned in the middle of the cutting edge so that it is the tip of the "V" which finishes cutting the electrical conductor. This allows the establishment of the electric arc in the middle of the device and a better balancing of the forces involved. In this embodiment, the passage is disposed in the extension or facing the tip of the "V". A second aspect of the invention relates to a current distribution device comprising at least one circuit breaker according to the first aspect of the invention.
    [0006] A third aspect of the invention relates to a motor vehicle having at least one circuit breaker according to the first aspect of the invention. Advantageously, the motor vehicle comprises means for storing electrical energy and an electric propulsion device 25 connected to the electrical energy storage means via said at least one circuit breaker. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which: - Figure 1 shows a sectional view in perspective of a pyrotechnic circuit breaker according to the invention, before operation; - Figure 2 shows a detail of the section of Figure 1, after operation of the circuit breaker; - Figure 3 shows a partial section of the circuit breaker along the axis III-III of Figure 2. Figure 1 shows a perspective view of a circuit breaker according to the invention, in section. A housing 1 is partially traversed by an electrical conductor 2, with the ends of the latter forming two connection terminals for the circuit breaker. The circuit breaker comprises a punch 4 and a die 3 which, before operation of the circuit breaker, are arranged on either side of the conductor 2, as shown in FIG. 1. The punch 4 has on its upper part opposite of the matrix 3 a groove delimited by two cutting edges 8 and 8 ', and a passage 6 which is a vertical groove connecting the cutting edge 8 with the bottom of the groove of the punch 4. Another passage, not visible, connects the cutting edge 8 'with the bottom of the groove of the punch 4. The utility of the passage 6 will be explained in particular in the paragraphs relating to FIG. 3. The punch 4 is represented here in a first position, in which the electrical conductor 2 is honest. To cut, the circuit breaker comprises a pyrotechnic actuator 5 (visible in Figure 2 only) which is arranged to pass the punch 4 in a second position, as shown in Figure 2. Figure 2 thus shows the section -circuit of Figure 1 after operation, that is to say with the electrical conductor 2 separated into three separate parts 21, 22, and 23. To obtain this result, the pyrotechnic actuator 5 (comprising an electro-pyrotechnic igniter by example), housed under the punch 4 was fired and generated gases so as to pressurize a combustion chamber 41. Under the effect of the gases and their pressure in the combustion chamber 41, the punch 4 is moved in a second position during a translation movement, during which the conductor 2 has been separated into three distinct parts 21, 22, and 23. As shown in Figure 1 or 3, the cutting edges 8 and 8 ' are not rectilig nes, but in Vé, so as to gradually cut the electrical conductor 2, with cutting forces lower than those necessary for simultaneous shearing of the entire section of the electrical conductor 2. Indeed, with these cutting edges 8 and 8 ' bevel or not perpendicular to the direction of movement of the punch 4, the section of the electrical conductor 2 is progressive. It may be noted that the punch 4 comprises a groove in which an O-ring is mounted, in order to guarantee a good seal of the combustion chamber 41. This gives a punching force of the punch 4 as high as possible, and the gases of the pyrotechnic actuator 5 can not go into the breaking chambers 7 and 7 ', which limits the possible pollution of the electric arc plasma with the gases of the pyrotechnic actuator 5. With the punch 4 in the second position, the groove of the punch 4 is engaged in the die 3, and two separate cutting chambers 7 and 7 'have been formed. The portion 21 of the electrical conductor 2 is therefore physically separated from the portion 22 of the electrical conductor 2 by the punch 4, which 25 limits the possibility of creating a direct electric arc between the parts 21 and 22, especially since in the second position, the punch 4 is tightly mounted on the die 3. This tight fit makes it possible to achieve several results. On the one hand, maintaining the punch 4 in the second position is guaranteed by this tight fitting, so that the separation of the breaking chambers 7 and 7 '-10- is guaranteed in time. It should be noted that the circuit breaker comprises a vent 9 (visible in FIG. 1) for each breaking chamber 7 and 7 ', and sealed, so that it opens only if the pressure in the chamber of cut 7 or 7 'concerned exceeds a threshold value.
    [0007] On the other hand, the tight fit makes it possible to cause or generate an elastic and / or plastic deformation of the punch and / or the die 3, which will thus be in surface contact with each other, with in the end a good sealing between the breaking chambers 7 and 7 '. This sealing makes it possible to avoid the creation of arcing between the breaking chambers 7 and 7 ', and the separate parts 21, 22. However, as mentioned above, a passage 6 connects the cutting edges 8 and 8' of the punch 4 at the bottom of the groove of the punch 4, as shown in FIG. 3, and this passage 6 makes it possible to locate with certainty the electric arcs created during the breaking of the electrical conductor 2. A first arc can thus be formed between the distinct part 21 and the distinct part 23, and a second can be formed between the distinct part 23 and the distinct part 22. The matrix can be deformed from 0 to 2 millimeters, preferably from 0 to 1 millimeter and even more preferably from 0 to 0.5 millimeters. For this purpose, a recess is provided between the die 3 and an insert 31, which allows such displacements and / or deformations. The insert 31 can be made of polyamide 6.6 and its main function is to reinforce the matrix 3. As shown, the insert 31 also forms a bore in which the punch 4 slides, which offers a direct positioning between the punch 4 and matrix 3, since it is the same room. Figure 3 shows a partial section along the axis III-III of Figure 2, without the matrix 3 (not shown for reasons of clarity). The portion 21 of the electrical conductor 2 has been moved upwards by the cutting edge 8, and folded into a Vee, due to the V-shape of the cutting edge 8 of the punch 4. The portion 23 of the electrical conductor 2 is as for it remained at the bottom of the groove of the punch 4, and we see in this figure 3 the passage 6 which connects the cutting edge 8 to the bottom of the groove of the punch 4. Due to the electrical characteristics of the circuit for which the cut circuit is provided (voltages ranging from 0V to 600V and currents ranging from OA to 5000A on inductive loads up to 2500pH (micro-Henry) for an intensity of less than 500A and up to 150pH for an intensity of 5000A ), an electric arc will be formed when the punch 4 passes from the first position to the second position, and cuts the electrical conductor 2. This electric arc, when the punch 4 is in the second position, will naturally go through the passage 6 , for the reason c i below. First, the punch 4 and the die 3 are in close fit, and only the passage 6 is a free passage between the breaking chamber 7 and the bottom of the groove of the punch 4. Finally, the passage 6 is arranged at the level of the shortest passage between the portion 21 of the electrical conductor 2 and the portion 23 of the electrical conductor 2. Indeed, the passage 6 opens in its upper part at the lower tip of the V of the portion 21 of the electrical conductor 2. Because of the cut into three distinct parts, two electric arcs are created in series, which increases the total voltage of the arcs and therefore the voltage across the circuit breaker which allows the value of the current in the circuit to be canceled. electrical circuit. Through the passage 6, the electric arc is located and must proceed through the passage 6. The invention further proposes to increase the voltage of the electric arc when it is formed. For this purpose, a material arranged to be removed by ablation is provided near the passageway 6, since the electric arc will be present therein. This material arranged to be removed (or eroded) by ablation will be sublimated and / or vaporized by the strong heat flux imposed by the electric arc, which will change the composition of the plasma of the electric arc and therefore its conductivity. By choosing the material to be removed by ablation among the plastics, the voltage across the arc is increased, and good results are obtained with POM said polyoxymethylene (or polyformaldehyde), since this material has a low ratio of carbon atom to oxygen atoms. Finally, it may be noted that the size of the passage 6 can condition the amount of material removed by ablation, the smaller the size of the groove forming the passage 6, the more erosion will be strong. Good results are obtained with a groove of a width ranging from 0.1 to 1 millimeter, and a depth ranging from 0.1 to 1 millimeter. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described herein without departing from the scope of the invention defined by the appended claims.
