Definitions

  • the present invention relates to an apparatus for breaking an electric current with separable electrical contacts and cut in air.
  • the invention relates to the field of electrical switchgear, such as low-voltage circuit breakers and high power.
  • Such devices comprise an electric current cut-off device comprising separable electrical contacts.
  • the member is switchable between open or closed positions to interrupt or, respectively, allow the circulation of an electric current within the device. This switching is controlled by means of a control mechanism, for example a rocking mechanism known as the "tumbler" in the English language.
  • These devices also include a trigger coupled to the control mechanism and which controls the control mechanism, so as to open the cut-off device when it detects an electrical fault.
  • the electrical fault is usually a short circuit or an overcurrent of the current flowing through the unit.
  • the trigger is magnetic, or thermal, or electronic.
  • the electrical contacts are partially separated from each other by an electromagnetic repulsion force, and are then in an unstable position. An electric arc appears between these electrical contacts.
  • the trigger must therefore control the opening of the cutoff device, as soon as this electric arc appears, to completely separate the electrical contacts, in order to safely interrupt the flow of electrical current in the device and ensure galvanic isolation. This interruption must occur as soon as possible after the occurrence of the electrical fault, for example in less than 5ms, to avoid damage to the device and avoid a situation that is unsafe. Indeed, it is essential to limit the amount of energy released during the cut.
  • the known devices do not give satisfaction because, in certain circumstances, the trigger has a reaction time to an electrical fault that is not short enough to react the control mechanism in the necessary time. There is therefore a risk that the cutter closes accidentally, thus preventing the interruption of the current.
  • Cutting devices are known to overcome this drawback and in which an overpressure within the apparatus, resulting from the release of cut gas caused by the electric arc, is used to trigger the control mechanism before the trigger can not go into action.
  • An example of such an apparatus is described in WO-2010/112420 .
  • the apparatus includes a piston that is in fluid communication with an arc-breaking chamber and is mechanically coupled to the control mechanism. In this way, an abnormal increase in pressure inside the apparatus causes a displacement of the piston, which then triggers the opening of the cut-off device, faster than the trigger associated with this device .
  • the invention more particularly intends to remedy, by proposing an apparatus for breaking an electric current with separable electrical contacts and cut in the air, this apparatus allowing a rapid opening of the electrical contacts in case electrical fault, while being simple to manufacture and having a satisfactory reliability.
  • the increase in pressure resulting from the appearance of the electric arc causes the deformation of the side walls.
  • the protrusion is rigid and integral with one of the side walls, it moves under the effect of the deformation of this side wall.
  • This displacement because of the relationship of the protrusion with the trigger member, causes the displacement of the trigger member to a trigger position to move the separable electrical contacts to the open position.
  • the triggering is done quickly, since the trigger chain of the control mechanism is shorter than in known devices, because of the absence of an intermediate element such as a piston.
  • the apparatus also has a simplified design, because, to the extent that the protrusion is provided on the side wall, it is easy to integrate during the manufacture of the side wall.
  • the Figures 1 to 5 represent an apparatus for breaking an electric current, for example a circuit breaker.
  • the apparatus 1 is a unipolar circuit breaker with alternating current or continuous low voltage and high intensity.
  • the apparatus 1 is adapted to operate with electrical voltages of less than 1500 V DC or 1000 V AC and with electric currents of short circuit of intensity greater than or equal to 1 kA.
  • the apparatus 1 may be different, for example, be a multipole circuit breaker.
  • the apparatus 1 is intended to be connected to an electrical circuit for protection against electrical faults.
  • electrical fault is meant here a short circuit or an overcurrent of the electric current flowing in the device.
  • the apparatus 1 comprises a cut-off block 2 including a cut-off member 3, also called cut-off assembly, a control mechanism 4 and a casing 5.
  • the apparatus 1 also comprises a trigger block 6, described in greater detail in FIG. what follows.
  • the cut-off member 3 and the control mechanism 4 are housed inside the casing 5, in internal compartments distinct from this casing 5.
  • the member 3 is switchable, reversibly and selectively, between two stable and distinct states, said open state and closed state.
  • the member 3 In the closed state, the member 3 allows the circulation of an electric current within the apparatus 1, for example between connection areas of this apparatus 1.
  • the member 3 prevents the circulation of an electric current in the absence of an electric arc within the apparatus 1.
  • opening of the member 3 means switching the member 3 from the closed state to the open state.
  • the member 3 comprises separable electrical contacts made of an electrically conductive material, such as copper. More specifically, the apparatus 1 here comprises fixed electrical contacts 31 and movable electrical contacts 32, the latter being movable relative to the fixed electrical contacts 31.
  • the fixed and movable electrical contacts 31 and 31 are here provided with electrically conductive contact pads respectively denoted 331 and 332.
  • the fixed and movable electrical contacts 31 and 32 are in contact with each other. Their respective contact pads 331, 332 are in direct contact, so as to allow the passage of current between these electrical contacts 31 and 32.
  • the electrical contacts 32 are remote from the fixed electrical contacts 31, so that their respective contact pads 331, 332 are electrically insulated by the ambient air.
  • the movable contacts 32 are formed by a single piece of electrically conductive material, which is carried by a rotary member 34 rotatably mounted relative to the housing 5.
  • the fixed contacts 31 are here two in number and are arranged symmetrically with respect to the axis of rotation of the member 34.
  • the member 3 also comprises arc breaking chambers 35, the role of which is to ensure the extinction of this electric arc.
  • the breaking chamber 35 comprises a stack of cutting plates 351, as well as a channel 352 for evacuating the cutoff gases, which fluidly connects the breaking chamber to the outside of the casing 5.
  • the chambers 35 are here two in number and are each placed at a contact zone between a fixed contact 31 and a movable contact 32.
  • the control mechanism 4 makes it possible to control the switching of the member 3 between the open and closed states.
  • the mechanism 4 is here mechanically coupled with the rotary member 34, so that a specific action on the mechanism 4 drives the electrical contacts 31 and 32 in displacement to switch the member 3 between the open states. and closed.
  • the control mechanism 4 comprises a lever 41, also called a crankpin, which is accessible from outside the housing 5 and which is intended to be handled by an operator to switch, through the mechanism 4, the cutoff member between the open and closed positions. To the figure 1 the lever 41 is in a position corresponding to the closed state of the cut-off member 3.
  • the control mechanism 4 also comprises a trigger member 42.
  • the member 42 is movable between a rest position and a trigger position. When the member 42 moves from the rest position to the trigger position, it triggers the mechanism 4, which then switches the member 3 to the open state. Once the member 3 is in the open state, it remains in this open state.
  • the mechanism 4 must be rearmed, for example by means of a manual action of an operator on the lever 41, to allow again the passage of the member 3 in its closed state.
  • the member 42 is then returned to its rest position by the mechanism 4, for example by means of a spring 422.
  • Mechanism 4 is here a rocking mechanism, also called "tumbler" in English. Such a mechanism is well known and, for example, is described in the patent application EP 0555158 A1 .
  • the mechanism 4 comprises the trigger member 42, a hook 43, a lock 44 and a connecting rod 45, the latter providing the mechanical coupling between the mechanism 4 and the rotary member 34.
  • the hook 43 is subject to an elastic restoring force, which tends to bring it back to a position corresponding to the open state of the member 3. This return movement is inhibited by the hooking of one end of the hook 43 on the latch 44, both that the latter is itself kept hooked to the trigger member 42 as long as it is in its rest position.
  • the triggering member 42 is here mounted in rotation, between its resting and tripping positions, about an axis of rotation X42 perpendicular to the side walls of the casing 5.
  • the trigger member 42 is here provided with a projecting lug 421, extending perpendicularly to the axis of rotation X42, the function of which is described in more detail in the following.
  • the trigger block 6 is configured to trigger the switching of the member 3 to the open state, through the mechanism 4, when an electrical fault is detected from the current flowing through the device 1.
  • the trigger block 6 comprises for this purpose a trigger 61, here of magneto-thermal type, which is adapted to monitor the electric current flowing in the trigger block and to move a striker 62 mobile block 6 when it detects the appearance of an electrical fault.
  • a trigger is well known to those skilled in the art and is not described here in more detail.
  • the block 6 is also provided with a connector 63 intended to be connected to the breaking block 2.
  • the triggering unit 6 is attached to the breaking block 2 and the connector 63 is electrically connected to a corresponding fixed electrical contact 31 of the member 3.
  • the triggering block 6 can react according to the current flowing through the electrical device 1.
  • connection areas of the device 1 There are “11” and “12” of the connection areas of the device 1. These areas 11 and 12 make it possible to connect the device 1 to the electrical circuit that it must protect.
  • the range 11 here corresponds to one end of one of the fixed electrical contacts 31, while the range 12 corresponds to an outer end of the connector 63.
  • the trigger 61 When an electrical fault is detected by the trigger 61, the latter moves the striker 62, which then exerts a mechanical force on the trigger member 42, so as to move it to its trigger position. In response, the control mechanism is triggered and causes switching and then maintaining the breaking device 3 in the open state, so as to interrupt the flow of electric current between the areas 11 and 12.
  • the casing 5 forms an outer casing of the cutoff block 2.
  • the trigger block 6 is detachable from the cutoff block 2.
  • the casing 5 forms an envelope of the only cutoff block 2.
  • the casing 5 surrounds at least the member 3 and the mechanism 4.
  • the triggering block 6 has its own case.
  • the housing 5 comprises in particular side walls 51, 52 which delimit opposite side faces of the cutoff block 2.

  • the side walls 51 and 52 are deformable, reversibly, between a normal state and a deformed state.
  • the side walls 51 and 52 have a substantially planar shape and extend parallel to each other.
  • each wall 51, 52 has a curved shape towards the outside of the apparatus 1, as illustrated in FIG. figure 4 .

However, when they are in a deformed state, they may not have a deformation strictly identical, that is to say of the same shape or the same amplitude, due in particular to the arrangement of the constituents of the apparatus 1 inside the housing 5.

  • the walls 51 and 52 elastically deform from their normal state to their deformed state as the pressure inside the housing 5 increases.
  • a deformation greater than or equal to 1 mm is observed when the pressure exceeds a value of 6 bars, this deformation being here measured along an axis parallel to the axis X42.
  • Such an increase in pressure is caused by the appearance of the electric arc during the separation between the fixed contacts 31 and the movable contacts 32 of the member 3.
  • the increase in pressure is such that the cutoff gas generated by the electric arc can not be instantly discharged into the outlet channel 352. They then spread inside the housing 5 and generate an overpressure, compared to the pressure that normally prevails in this housing 5. For example the pressure increases until it is greater than or equal to 6 bars, or even greater than or equal to 20 bars.
  • the electric arc must be interrupted as soon as possible to limit this overpressure. For example, it is desirable to open the member 3 before the pressure in the housing becomes greater than or equal to 5 bars.
  • the housing 5 is made from a thermoplastic material, for example by molding.
  • the walls 51 and 52 are made of the same material as the housing 5.

  • the walls 51, 52 each have a thickness greater than or equal to 1 mm and less than or equal to 3 mm, this thickness being measured when the walls 51, 52 are in the idle state.
  • the walls 51, 52 return to their state of rest when the pressure in the housing 5 becomes equal to the surrounding atmospheric pressure, without the housing 5 suffering from mechanical sequelae detrimental to its operation.
  • the housing 5 is here formed by two molded half-shells, similar and complementary in shape to each other, each carrying a wall 51, 52. These two half-shells are intended to be secured to one another to ensure the integrity of the housing 5.
  • the housing 5 comprises means for fixing the walls 51, 52.

  • the protrusion 53 Due to its attachment to the deformable side wall 52, the protrusion 53 is movable between a first position and a second position. The protrusion 53 is in the first position when the side wall 52 is in the normal state, and in the second position when the side wall 52 is in the deformed state.

  • the choice of the dimensions of the protrusion 53, in particular its shape and / or section, as well as the use of the stiffener 532, make it possible to increase the stiffness of the protrusion 53. This is particularly useful when the protrusion 53 is made in one piece with the side wall 52. Indeed, the protrusion is then made of the same material as the side wall 52. Now, this material is deformable, while it is precisely desired to prevent the protrusion 53 it itself does not deform when it exerts a support on the organ 42.
  • the protrusion 53 thus makes it possible to trigger the control mechanism 4 during the occurrence of an electric arc between electrical contacts 31, 32, which generates a clearance of cut-off gas and therefore an overpressure in the housing 5.
  • the protrusion 53 then exerts a force on the lug 421, which causes the displacement of the trigger member 42 towards its trigger position, as illustrated by the arrow F3 at the figure 5 . Because of the design of the mechanism 4, this movement of the member 42 in turn causes the switching of the member 3 to its open state, as explained above.
  • the electrical contacts 31 and 32 are then kept separate, thus ensuring the stop of the flow of electric current.
  • the increase in pressure which results from the appearance of the electric arc causes the deformation of the side walls 51, 52 and therefore the triggering of the mechanism 4, via the protrusion 53.
  • the trigger mechanism 4 is achieved quickly, since the trigger chain is shorter than in known devices, because of the absence of an intermediate element such as a piston.
  • the overpressure triggers the trigger mechanism 4 after a period of less than or equal to 1 ms.
  • the trigger 61 comes into action, moving the firing pin 62, after a period of 3 ms.
  • the manufacture of the device 1 is simpler and more economical. This also gives the device 1 a better robustness, insofar as the operation of the protrusion 53, because of its simplicity, is not sensitive to a possible risk of pollution by the cutoff gases.
  • protrusion 53 is configured to act on the trigger member 42 triggers the mechanism 4 using the same control chain as the trigger 61. It is therefore not necessary to change the architecture mechanisms existing controls, and to increase the external volume and size of the cut-off block 2.
  • the invention thus makes it possible to use the deformation of the side walls 51 and 52 caused by the overpressure due to the cutting gas, which is traditionally perceived as a harmful and undesirable effect, in order to control the triggering of the mechanism 4 quickly and reliably and with a simplified implementation.
  • the figure 6 represents an electrical switching device 1 'according to the second embodiment of the invention.
  • the elements of the apparatus 1 'of this embodiment which are analogous to the switchgear 1 bear the same references increased by the symbol "'" and are not described in more detail, since the description below above can be transposed to them.

  • Block 2 'differs in particular from block 2 in that it comprises two cut-off devices, or cut-off assemblies, each associated with one of the electric poles P1 and P2.
  • the apparatus 1 'then comprises a plurality of connection pads associated with each of the poles P1 and P2.
  • the block 2 ' also comprises a control mechanism similar to the mechanism 4, in particular provided with a lever 41' and a trigger member 42 'including a lug 421'.
  • the control mechanism of the block 2 ' is arranged to simultaneously control the two cut-off members of the block 2' in the same state, in particular to open simultaneously the two cut-off members of the poles P1 and P2.
  • the apparatus 1 ' comprises a housing similar to the housing 5 and inside which the block 2' is housed.
  • This housing has deformable side walls 51 'and 52' similar to the walls 51, 52.
  • the wall 52 ' carries a protrusion 53' which plays the same role as the protrusion 53.
  • the protrusion 53 ' is adapted to move towards its second position when the wall 52' is deformed, under the effect of an increase in the pressure in the housing, resulting from the occurrence of an electric arc in at least one of the cut-off members of the block 2 '.
  • the protrusion 53 ' exerts a force on the lug 421', which moves the member 42 'towards its release position in order to open the cut-off members of the block 2'.
  • the invention is easily applicable to devices other than the apparatus 1, without the need to modify their architecture in depth.
  • the distance previously defined between the contact zone and the wall 52' is here equal to the distance between the wall 52 'and the geometric plane separating one on the other, the two cut-off members of the block 2 '.
  • the apparatus 1 ' also comprises a cover 500 intended to cover a front face of the apparatus 1'.
  • This cover 500 is provided with lateral flanges 502 folded which are intended to cover the front edge of the side faces 51 ', 52' when the cover 500 is in configuration mounted on the apparatus 1 '.
  • the dimensions of the flanges 502 are limited so as not to hinder the deformation of the walls 51 'and 52'.
