Definitions
- the present invention generally relates to a pyrotechnic circuit breaker intended to be mounted for example on a motor vehicle, and in particular in an electric power circuit of a motor vehicle, for example a hybrid vehicle or an electric vehicle.
- Circuit breaker devices are known in the prior art, such as that described in document US20130175144, which proposes using an insulating material that can flow.
- this system has in particular the disadvantage of requiring a lot of insulating material which can creep, which requires large quantities, can generate leaks.
- precautions and authorizations will be necessary for automotive use (due to incompatibility with paint, for example).
- An object of the present invention is to respond to the drawbacks of the prior art mentioned above and in particular, first of all, to propose a pyrotechnic circuit breaker that is simple to manufacture, having high cutting capacities, a fast opening when operating, and good insulation resistance after opening.
- a first aspect of the invention relates to a pyrotechnic circuit breaker comprising:
- an opening member movable and arranged to open a part to be opened of the internal electrical circuit when moving between an initial position and a final position, so as to form at least two separate conductor portions after opening
- a pyrotechnic actuator arranged to move the opening member from the initial position to the final position
- an internal chamber receiving the part to be opened, characterized in that the internal chamber comprises or contains at least one wall formed with a plastic material comprising silicone.
- the internal chamber may comprise or contain at least one wall formed with a plastic material comprising silicone, arranged facing the part to be cut.
- at least one wall of the internal chamber comprises silicone and this wall can typically form or support a leakage current path.
- adding silicone to a material forming the wall makes it possible to guarantee high insulation resistances after use, in comparison with the same circuit breaker not comprising silicone in a wall of the internal chamber.
- providing silicone in the material of one of the walls capable of supporting or forming a leakage current path after breaking makes it possible to significantly reduce the leakage currents once the breaking has been performed.
- the internal chamber comprises or contains at least one wall formed with a plastic material comprising an additive, the additive comprising silicone or being silicone.
- the internal chamber can be provided to be exposed to a pressure generated by the pyrotechnic actuator.
- the pressure generated by the pyrotechnic actuator can be greater than 5 MPa, preferably greater than 10 MPa. Consequently, the wall formed with a plastic material comprising the silicone can also be exposed to the pressure generated by the pyrotechnic actuator.
- the wall formed with a plastic material comprising the silicone can be provided to resist the pressure generated by the pyrotechnic actuator.
- the wall formed with a plastic material comprising silicone is part of the structure of the circuit breaker, and participates in the resistance to the pressure generated by the pyrotechnic actuator.
- the pyrotechnic circuit breaker can comprise at least one support, and the plastic material comprising silicone can be overmolded or attached to the support.
- the plastic material comprising silicone can be overmolded or attached to the support.
- the support may comprise a portion of the electrical conductor.
- the support may comprise a portion of the casing. According to one embodiment, the support may comprise a portion of the opening member.
- the wall formed with the plastic material comprising silicone can support a leakage current path between the two separate conductor portions after opening, and preferably the shortest leakage current path between the two separate conductor portions after opening.
- the wall formed with the plastic material comprising silicone can cover less than 50% of a total surface of the internal chamber.
- Such an implementation makes it possible to limit the use or addition of silicone only where this will have a noticeable effect on the insulation resistances.
- the plastic material comprising silicone may comprise a polymer of the polyamide type, preferably a polyphthalamide of the PA6T/XT type.
- the plastic material can be a polymer of the polyamide type, preferably a polyphthalamide of the PA6T/XT type, with an additive comprising silicone. Provision may be made to have predominantly (for example more than 80% by weight, preferably more than 90% by weight) a polymer of the polyamide type, preferably a polyphthalamide of the PA6T/XT type, and a minor additive comprising silicone.
- the plastic material comprising silicone may comprise silicone and/or polysiloxane, in a proportion ranging from 3.5% to 6.5% by weight, and preferably from 4.25% to 5.75% by weight.
- the internal chamber may comprise or contain at least one internal surface formed by a wall formed with a second plastic material comprising a flame retardant.
- the circuit breaker comprises a wall arranged in the internal chamber, that is to say opposite the part to be cut, and which contains a flame retardant.
- the insulation resistances after operation were higher than those measured on circuit breakers having the same geometric configuration, but no material with a flame retardant.
- providing a flame retardant in the material of one of the walls exposed to the electric arc formed during the cut makes it possible to significantly reduce the leakage currents once the cut has been made.
- combining a wall with silicone and another wall with a flame retardant makes it possible to amplify the effects on the insulation resistance. In other words, a synergy was noted by combining these two characteristics.
- said second plastic material comprising the flame retardant can be a polymer, such as a polyamide, and preferably a polyphthalamide such as PA 6T/66.
- said second plastic material comprising the flame retardant can be a polymer forming a matrix, and comprising a filler material, such as fibers, preferably inorganic fibers, for example glass fibers, in a proportion ranging from 10% to 70% by weight and preferably in a proportion ranging from 45% to 55% by weight.
- a filler material such as fibers, preferably inorganic fibers, for example glass fibers
- said second plastic material comprising the flame retardant can self-extinguish after 10 seconds, during a flammability test according to standard LJL94 (6th edition of March 28, 2013) carried out on a vertical specimen, loss of particles being authorized as long as the lost particles are not ignited.
- the flame retardant can be a non-halogenated compound, selected from:
- the flame retardant may be a non-halogenated compound, selected from the following compounds and their mixtures: melamine cyanurate, melamine phosphate, melamine pyrophosphate, melamine polyphosphate, melem phosphate (i.e. i.e. 2,5,8-triaminoheptazine phosphate), melem pyrophosphate, dimelamine pyrophosphate, dimelamine phosphate, melem polyphosphate, phosphaphenanthrenes, metal hydroxides, salts of phosphinic acid, salts of diphosphinic acid.
- melamine cyanurate melamine phosphate
- melamine pyrophosphate melamine polyphosphate
- melem phosphate i.e. i.e. 2,5,8-triaminoheptazine phosphate
- melem pyrophosphate dimelamine pyrophosphate
- dimelamine phosphate dimelamine phosphate
- melem polyphosphate
- the pyrotechnic circuit breaker can comprise a base part formed by a third plastic material, and said second plastic material comprising the flame retardant can be attached or overmolded on the base part.
- the opening member may comprise:
- said third material may be a polyamide, preferably a polyphthalamide (PA 6.T/XT) forming a matrix, and possibly comprising glass fibers, in a proportion ranging from 40% to 50% by weight .
- the third material makes it possible to provide a robust opening body which is resistant to mechanical stresses.
- the pyrotechnic circuit breaker can be arranged to generate an electric arc between the two separate conductor portions when the opening member moves between the initial position and the final position, when the circuit breaker is connected to a live electrical circuit, and the second plastic material comprising the flame retardant can be arranged to be removed by ablation by the electric arc.
- the second plastic material comprising the flame retardant arranged to be removed by ablation is transformed (for example sublimated) under the action of the intense heat flux of the electric arc. This second material, removed by ablation, can then condense or deposit on the walls of the internal chamber, and this provides high insulation resistances.
- Such an implementation can modify the composition of the electric arc plasma and its conductivity, and makes it possible to increase the electric arc voltage.
- Such electric arcs can be created when the circuit breaker is connected to a live electrical circuit, with voltages ranging from 0V to 1000V and currents ranging from 0A to 25000A on inductive loads of up to 2500mH (micro- Henry) for an intensity lower than 500A and up to 5mH for an intensity of 25000A.
- the circuit breaker according to the invention makes it possible to cut off the current reliably in less than 10 ms and even less than 5 ms, in a definitive manner, because the circuit breaker, comprising a pyrotechnic actuator, this can only serve a time.
- the circuit breaker When used, the circuit breaker also has good insulation resistance.
- the pyrotechnic circuit breaker may comprise at least one passage arranged to guide the electric arc between the two separate conductor portions, and the second plastic material comprising the flame retardant may be arranged to form or delimit at least partially the passage.
- the second plastic material comprising the flame retardant is necessarily exposed to the electric arc.
- the passage can be at least partially formed on the opening member.
- an insulation resistance between the connection terminals can be greater than 30Mohms, preferably greater than SOMohms, preferably greater than 10OMohms, preferably greater than 500Mohms, and very preferably greater than 1 Gohms.
- Another aspect of the invention relates to a method of manufacturing a circuit breaker according to the first aspect, comprising the steps consisting in:
- a movable opening member arranged to open a part to be opened of the internal electrical circuit when moving between an initial position and a final position, so as to form at least two separate conductor portions after opening
- the method comprises a step consisting in forming the internal chamber with at least one wall formed with a plastic material comprising silicone, by adding to a first raw material, for example in granules, intended to form the internal chamber a second raw material, for example in granules, comprising between 40% and 60% by weight of silicone.
- the method according to the invention comprises a step consisting in mixing, before the manufacture of the internal chamber, the first raw material, for example in granules, intended to form the internal chamber, with the second raw material, for example in granules, comprising between 40% and 60% by weight of silicone.
- the wall comprising the silicone is formed by an injection-molding process, and the manufacturing process includes a step of preparing the material to be injected by mixing two types of granules: the first raw material and the second raw material which contains silicone. There is therefore no pure silicone to provide or handle, just solid granules already comprising the silicone. This implementation makes it possible to keep a simple process.
- Another aspect of the invention relates to a motor vehicle comprising at least one circuit breaker according to the first aspect.
- FIG. 1 shows a sectional view of a pyrotechnic circuit breaker, comprising in particular a casing through which an electrical conductor passes forming an internal electrical circuit, a pyrotechnic actuator and an opening member arranged to open the internal electrical circuit when the pyrotechnic actuator is actuated or triggered;
- FIG. 2 shows a detail of the case of the circuit breaker of FIG. 1;
- FIG. 3 shows a detail of the circuit breaker opening member of FIG. 1
- FIG. 4 shows a detail of a section of the circuit breaker of FIG. 1 after actuation or triggering of the pyrotechnic actuator
- FIG. 5 schematically represents a section in top view of the circuit breaker of FIG. 1. Detailed description of embodiment(s)
- FIG. 1 represents a circuit breaker comprising in particular:
- a housing 10 formed by a lower housing portion 12 and an upper housing portion 11,
- connection terminals 21 and 22 an internal electrical circuit connecting the two connection terminals 21 and 22 and formed by an electrical conductor 31,
- an opening member 40 movable and arranged to open a part to be opened 31 A of the internal electrical circuit when moving between an initial position (according to FIG. 1) and a final position (according to FIG. 4), so as to form at least two separate conductor portions 32 and 33 (visible in Figure 4) after opening,
- a pyrotechnic actuator 50 arranged to move the opening member 40 from the initial position to the final position
- an internal chamber 60 (comprising a lower chamber 62 and an upper chamber 61), defined by one or more internal wall(s) formed in the casing 10, and receiving the part to be opened 31 A,
- the circuit breaker of FIG. 1 is typically integrated into a power circuit of a motor vehicle (an electric vehicle for example) and can be used to cut off the power circuit if an emergency situation arises.
- a motor vehicle an electric vehicle for example
- One of the functions of this circuit breaker is therefore to be able to cut off a power circuit quickly, even if strong currents are present (more than 500 amps for example).
- Another function of this circuit breaker is to guarantee good insulation resistance between the connection terminals 21 and 22 after opening the internal electrical circuit.
- the pyrotechnic actuator 50 (typically an electro pyrotechnic igniter) is triggered and a strong pressure is generated in the space between the pyrotechnic actuator 50 and the opening member 40, which pushes the latter upwards in figure 1, to move from the initial position shown to the final position in figure 4.
- an opening can alternatively be provided by pushing one of two initially separate strands and in contact with each other, to separate them.
- the opening member 40 comprises two projections 45, separated by a groove 46, and which form knives to cut the part to be opened 31A.
- the part to be opened 31 A comprises a central portion supported by a return 13 of the upper casing portion 11 , engaged with a strip 14 molded onto the central portion of the part to be opened 31 A and integral with a molded body 15, molded onto the electrical conductor 31 .
- the projections 45 of the opening member 40 bear on the unsupported parts of the electrical conductor 31 and shear it from side to side. other of the bar 14 and the return 13 (at the level of the part to be opened 31 A facing the upper chamber 61). It is however possible to provide alternatively to have a single projection 45 or more than two projections 45, the number of projections 45 defining the number of cutouts made on the electrical conductor 31 during the movement of the opening member 40. As shown in Figure 4, the shearing of the electrical conductor 31 forms:
- an electric arc can form (depending on whether current crosses the electrical conductor 31 or not) between each internal end 34 and the central portion 33, at the level of an arc path TA shown in dotted lines in FIG. 4.
- the opening member 40 pushes and causes each distinct part lateral 32, so that the arc path TA "stretch” or "lengthen” to present, at the end of operation, a free distance sufficient to guarantee extinction of the electric arc and rapid breaking or opening of the electrical circuit internal.
- Figures 2 and 3 show the mounting of the opening member 40 in the housing 10, and in particular, guide units are provided between the opening member 40 and the housing 10, at the level of the molded body 15
- the opening member 40 (FIG. 3) is provided with lateral projections 43 forming guide protuberances, and the molded body 15 with lateral grooves 613 forming guide grooves, formed in the side walls 611 of the upper chamber 61 (visible in Figure 2).
- the opening member 40 is therefore mounted in sliding connection or in translation with respect to the housing 10 and slides during its movement from the initial position to the final position, which provides reproducible and controlled operation and final position to guarantee rapid opening and arc extinction at the end of operation with sufficient free distance.
- the operation of the pyrotechnic actuator 50 can generate numerous particles and hot gases which are projected into the internal chamber 60, and which typically cover or condense on the walls of the latter, and in particular the walls 611 , the projections lateral 43 and the lateral grooves 613.
- Such deposits can form an electrically conductive or weakly conductive layer, and an insulation resistance, after opening of the electrical conductor 31, can be affected.
- the electric arc can remove by ablation material from the opening member 40 and/or from the housing 10 (return 13 or bar 14 in particular), which can generate gases or particles which will also cover and /or condense on the walls of the internal chamber 60 and also affect the insulation resistance.
- connection terminals 21 and 22 Such an insulation resistance, measured after operation, between the connection terminals 21 and 22 must be high, to guarantee the absence of leakage current between the connection terminals 21 and 22 after opening of the internal electric circuit of the circuit breaker.
- leakage currents typically travel through leakage current paths between the separate conductor portions after opening, which travel along the inner wall of the inner chamber 60.
- Figure 5 shows a schematic section (thus not showing all the details of Figure 1) of the circuit breaker of Figure 1 after opening, in a plane passing through the upper face of the electrical conductor 31, seen from above.
- the electrical conductor 31 has therefore been opened into three distinct conductor portions, that is to say two distinct lateral portions 32 and a central portion 33.
- the central portion 33 is separated from the two distinct lateral portions 32 by the lateral projections 45 of the opening member 40.
- Detail A and detail B of Figure 5 show that a leakage current can travel along a CCF leakage current path formed along the inner wall of the internal chamber 60, in particular between the lower corner 32A of the distinct lateral portion 32 and the lower corner 33A of the central portion 33 which is the shortest leakage current path.
- the function of providing good insulation resistance is to be ensured after operation, once the electrical conductor 31 has been cut or opened.
- a leakage current cannot be established along the arc path TA because the resistivity of the air is too high. Consequently, a leakage current can only travel along the walls of the circuit breaker, in particular the internal walls of the internal chamber 60 or the walls of the opening member 40, and this preferably on the path most short, which has the lowest insulation resistance.
- the CCF leakage current path travels or extends along the wall of the internal chamber 60.
- the insulation resistance between the connection terminals be greater than 30Mohms, preferably greater than 50Mohms, preferably greater than 100Mohms, preferably greater than 500Mohms, and very preferably greater than IGohms, even if particles or condensed gases have deposited on the inner wall of the inner chamber.
- it can be, in a first alternative, proposed to provide in the internal chamber 60 a wall formed with a plastic material comprising silicone. Indeed, the applicant has noticed that the addition of silicone, in particular in a wall on which a leakage current could flow after the operation of the circuit breaker, makes it possible to significantly increase the insulation resistances after operation.
- the plastic material comprising silicone comprises a polymer of polyamide type, preferably a polyphthalamide, such as PA6T/XT.
- the plastic material including silicone comprises silicone and/or polysiloxane, in a proportion ranging from 3.5% to 6.5% by weight, and preferably from 4.25% to 5.75% by weight.
- the insulation resistances after openings are markedly higher with the parts whose overmolded body 15 comprises 10% silicone, than on the reference parts whose overmolded body 15 does not comprise silicone.
- the second plastic material comprising the flame retardant can typically be a polyamide, and preferably a polyphthalamide (such as PA 6T/66). It is possible to provide reinforcing fibers, for example glass fibers in a ratio of 45% to 55% by weight.

- the insulation resistances after opening are significantly higher with the parts whose internal chamber comprises a surface exposed to the electric arc formed by the second material comprising the flame retardant, than on reference parts that do not include flame retardant.
