- At least one of the aforementioned fabrics comprises threads wavy passing alternately below and above two straight wires at a time, each times with offset of a straight wire compared to the previous wavy wire, the wavy wires being nested.
- the corrugated threads are the weft threads.
- the diameter of the corrugated wires is smaller than that of the wires rights.
- it comprises at least two superimposed fabrics having different size mesh openings.
- it comprises at least three superimposed fabrics having openings of progressive mesh, the fabric with the largest mesh openings says first fabric, being crossed first by the gases.
- the aforementioned first fabric has a diameter of wavy and straight threads greater than 0.5 mm and a nominal opening greater than 400 ⁇ m, while the latter fabric has a nominal opening of less than 200 ⁇ m.
- the invention also relates to an arc extinguishing chamber in particular for low-voltage multipole circuit breaker with insulated molded case, comprising per pole: one pair of fixed and movable separable contacts, a contact actuation mechanism mobile, metal sheets for cooling the arc drawn between said contacts during their separation, a cut-off gas exhaust port in the housing at the exit from said chamber and a deionization device according to any one of previous claims arranged in the vicinity of said exhaust port for cooling the breaking gases leaving towards the outside environment.
- this room also comprises at least one screen additional perforated in insulating material, placed between the ends of the above cooling and porous screen.
- this chamber also comprises, perforated sheets or stiffeners placed on either side of the porous screen in order to increase its resistance mechanical to the pressure wave.
- Figures 9, 10 and 11 are partial views, in section, illustrating two meshes triangular associated respectively with a reps fabric of plain chain, with a reps fabric of crossed chain and a reps fabric of solid chain with high porosity.
- FIG 1 we see a low-voltage multipole circuit breaker Dr with housing made of material molded insulation and manual control handle.
- This Dr circuit breaker comprises by pole an arc extinguishing chamber 1 housed in a lower compartment of the housing B.
- Each arc extinguishing chamber 1 includes a pair of separable contacts 2, 3 and a stack of V-shaped notched cooling sheets 4 extending transversely to the direction of extension of the arc drawn between contacts 2, 3 when they separate after tripping of the circuit breaker.
- the fixed contact 2 is supported by a shaped conductor 5 U-shaped pin, positioned on an intermediate wall 6 of the housing B and in connection electric with an external connection area 7.
- a shielding element 8 metal is inserted between the two branches of the conductor pin 5 and has a extension 9 playing the role of end separator.
- the movable contact 3 is integral with a contact arm 10 associated with a pivoting bar of the actuating mechanism (not shown) common to all poles.
- a connecting braid 11 connects the opposite end from arm 10 to the thermal and electromagnetic triggers (not shown) of each pole.
- the transverse face of the lower compartment of the housing B is provided with a cut-off gas exhaust port 12 at the outlet of each chamber arc extinction 1.
- a gas deionization device designated by the general reference R, is arranged in each exhaust port 12 to reduce the manifestations of the ionized gases thanks to efficient cooling of the hot gases at the outlet of chamber 1.
- Each deionization device R cooperates with the sheets 4 and includes a porous screen E formed by the juxtaposition of several metallic fabrics called reps T.
- These reps T fabrics are generally formed by an intertwining of straight threads 15 spaced and parallel to each other with tightly knit corrugated wires 16 passing alternately above and below one or more of the successive straight wires 15, in extending substantially perpendicular to said straight wires 15.
- rep T fabrics can have different structures, for example a structure united reps or a cross rep structure.
- the united reps structure represented on the Figures 2, 4 and 6, the fabric T is formed of parallel straight threads 15 and wavy threads 16 passing alternately above and below successive straight wires 15, one at a time, and each times, with offset of a straight wire 15 with respect to the preceding wavy wire, that is to say that two adjacent wavy wires 16 pass respectively above and below the same wire right 15.
- each fabric T is formed of straight wires 15 and corrugated wires 16, each corrugated wire 16 passing alternately through above and below two straight wires 15 both with offset of a straight wire 15 by compared to the previous corrugated wire, the corrugated wires 16 being nested
- the parameters defining these structures are inter alia the diameters of the straight wires 15 and corrugated 16, the spacing (or not) of the straight wires 15, the nominal or empty opening of mesh, which corresponds, as illustrated in Figures 9, 10, 11 to the diameter of the sphere S tangent to the wires 16a, 16b forming the mesh.
- the diameter d of the wires corrugated 16 will be less than the diameter D of the straight wires 15. This weaving makes it possible to obtain mesh openings significantly smaller than the diameter d, D of the constituent wires 15, 16 some cobweb.
- the porous screen E is constituted by several fabrics T as described previously, stacked on top of each other (advantageously, between 2 and 5 fabrics). These juxtaposed fabrics T have progressive mesh openings, fabric T having the openings the most important, i.e. with the largest wire diameter, being located so as to be crossed first by the gases. So this first fabric has a significant thermomechanical robustness, necessary for the first gas filtering element while the latter will have the minimum mesh opening required for maximum cooling of the breaking gases.
- the diameters d, D of threads (wavy and straight) associated with the first fabric will be greater than 0.5 mm and the opening nominal greater than 400 ⁇ m, while the nominal mesh opening associated with the last tissue will be less than 200 ⁇ m.
- an additional screen 17 of insulating material will advantageously placed in the exhaust zone of the arc extinguishing chamber 1, in the gap between the ends of the sheets 4 and the porous screen E according to the invention.
- This insulating screen 17 disposed opposite the porous screen E has a perforation regular and perfectly defined allowing gas circulation. This screen 17 is intended to prevent the arc from looping back on the metal elements of the filter.
- perforated sheets or stiffeners may be added on both sides of the porous screen E. These perforated sheets will allow stir the gas and increase the mechanical strength of the assembly in order to resist the pressure wave associated with breaking short-circuit currents.
- the ionized gases cross the meshes M formed in the different layers of fabric, each mesh M being defined as more particularly visible in FIGS. 9 to 11, whatever the structure of the fabric, united reps or crossed reps, by a straight thread 15 and two threads wavy 16 tangents to each other in the median p plane of the fabric.
- the ionized gas flows at through these passages of minimum section being strongly disturbed in terms of direction and speed.
- Figures 7 and 8 to observe the gas path respectively in a plain reps fabric and a crossed reps fabric.
- the fabric T it is necessary for the fabric T to retain a certain porosity in order to allow an exit of the gases thus limiting the overpressure appearing in the device. It will therefore be necessary to find a compromise between the exhaust section and the exchange surface.
- rep tissue may be considered such as for example, the high porosity reps fabric as illustrated in FIG. 11, in which the threads the finest 20 are of a diameter less than the diameter of the sphere S tangent to the wires forming the mesh M.
- the material constituting the wires may be any metallic material which conducts heat and corrosion resistant such as stainless steel or nickel.
- the number of superimposed fabrics will be adapted according to the arc energy developed in the breaking chamber. For example, for an energy of 200kj, four thicknesses will be used.
