Definitions

  • the present invention relates to an electrical switching device for installation AC low voltage electric with at least two phase conductors with or without neutral conductor, comprising a cut-off module per conductor and a control module provided with an actuation mechanism for said modules cutoff, each cutoff module comprising at least one input terminal connected to a fixed contact, one output terminal connected to a fixed contact, two others fixed contacts connected together by a bridge or a fuse and forming with the others fixed contacts two pairs of fixed contacts and two associated movable contacts respectively to a pair of fixed contacts, an engaged position and a position triggered, the control module comprising at least one control axis coupled to an operating handle, this axis passing through said cut-off modules and carrying at least one cam coupled to at least one moving unit in translation coupled to said movable contacts to be moved from a first stable position called position engaged to a second stable position called triggered position.
  • breaking devices commonly called switches, fuse switches or change-over switches are used to distribute energy to installations electrical or to order industrial equipment in low AC voltage, for example 380 V, and in a current range of a few tens to a few thousands of amps.
  • the so-called double-cut devices have two movable contacts by pole or breaking module.
  • contacts mobiles consist of a rectilinear bar which performs between its two positions stable a pure translational movement and the fixed contacts of the same pair are arranged in the same plane parallel to said mobile contact.
  • the movement of translation of the movable contacts is traditionally obtained by an integral cam at its center of the control axis of the cut-off modules.
  • the cam may have an almost oval shape and have a guide path on its edge.
  • each mobile contact is connected to a mobile equipment provided on either side of the control axis and applied against the edge of the oval cam by means of a spring.
  • the rotation of the cam generated by the rotation of the control axis causes the moving part in a movement of radial translation transmitted simultaneously to the corresponding mobile contact.
  • the almost oval shape of the cam is generally optimized to allow a sudden cut and an optimal maneuvering effort.
  • the cam can also have a round shape on which the crews are fixed movable at eccentric points, thus forming a connecting rod-wheel system. So the rotation of the cam also causes the radial translation of the moving assembly which is transmitted to the corresponding mobile contact.
  • the known and briefly described breaking devices above have many disadvantages. Because the movable contacts move of pure translation, there is no friction between the movable contacts and the contacts fixed at the time of switching on and off. Therefore, there is no self-cleaning of the contact surfaces. This lack is detrimental to the quality of the electric contact. In particular, the contact resistance increases with the number of maneuvers performed and the number of arcs established between the contacts fixed and mobile. The deterioration in the quality of the electrical contact causes a overheating of the contact surfaces and of the device in general, inducing losses by the Joules effect, as well as a reduction in the service life of both contacts and the device. On the other hand, in conventional devices, the number of parts is relatively large.
  • the effort applied to mobile contact corresponds to that applied by the cam integral with the control axis itself secured to the operating handle.
  • the object of the present invention is to overcome these drawbacks by proposing a breaking device with a new geometry of fixed and mobile contacts promoting self-cleaning of the contact surfaces but above all increasing the effort contact for the same force applied by the cam.
  • the switching device proposed has a newly arranged cam to respond to different characteristics required for switching on and off so to optimize the operating conditions as much as possible.
  • each movable contact has two contact surfaces arranged in substantially perpendicular planes, in that the fixed contacts of the same pair are arranged in substantially perpendicular planes of so that their respective contact surface is placed opposite the surface corresponding contact provided on said movable contact when it is in position engaged and in that each movable contact moves in radial translation by relative to the control axis in a direction substantially perpendicular to a straight passing through its two contact surfaces.
  • each movable contact has two end branches arranged on either side of a middle branch and forming a angle of approximately 45 ° with respect to said middle branch, the surfaces of contact being provided on the two end branches.
  • the movable assembly advantageously consists of a substantially rectangular extending transversely across said modules of the cutoff and arranged in an inclined plane substantially parallel to the control axis.
  • the frame may have at least two parallel walls, oriented radially by relative to the control axis and arranged to slide along two walls corresponding formed in the housing of said apparatus for guiding said frame in translation.
  • the frame comprises, for each movable contact corresponding, a window oriented substantially perpendicular to the axis of control and a return spring housed in this window to request said contact movable towards the fixed contacts.
  • the frame also includes at least one notch intended to receive said cam, at least one wall of this notch comprising a substantially training finger parallel to the control axis and engaged in at least one track provided in said cam.
  • the cam comprises, for each movable assembly, a groove non-circular, delimited by an internal wall close to the control axis and a outer wall remote from the control axis, these walls being arranged to guide said drive finger, respectively on switching on and off.
  • the bottom of the groove advantageously has different reliefs arranged to define, respectively with the internal and external walls, two distinct tracks either a forward track for triggering and a return track for triggering.
  • the forward track has a first part substantially straight and a second circular part of small radius eccentric by relative to the control axis and the return track has a first circular part of constant radius centered on the control axis and a second circular part of which the radius is less than said constant radius.
  • the second part of the outward track communicates with the first part of the track back by a shoulder.
  • This cam advantageously comprises a central barrel integral in rotation with the axis of control and sliding on the latter and the notch provided as part of the crew mobile has a width greater than that of the cam allowing it to axial travel corresponding to the differences in relief of the bottom of the groove.
  • the barrel has at least one of its free ends a cam profile cooperating with at least one lug provided at least in the housing of said cam device and oriented radially with respect to the control axis and the control axis carries a return spring arranged to maintain the cam profile in abutment on said lug.
  • the groove can extend in one direction opposite to that of the outward and return tracks, by a test track, framed by the walls internal and external, this track being circular, close to the control axis, of radius constant centered on this axis.
  • the cam has on its rear face a close circular groove of the control axis and centered on this axis and the frame of the mobile assembly comprises a guide shoe 46 disposed opposite the drive finger 45 and arranged for be housed in said groove when the device is in the test position.
  • the switching device 1 comprises, in the example shown, a control module 2 and three breaking modules 3.
  • This device is intended for a three-phase electrical installation, i.e. with three phase conductors, but could be adapted to any other installation.
  • the cut-off modules 3 are either made up of independent boxes, juxtaposed and assembled by any known means, or grouped in a single box 4.
  • Each cut-off module 3 is associated with a conductor of said installation and includes known manner an input terminal 30 connected to a fixed contact 31, an output terminal 32 connected to a fixed contact 33, two other fixed contacts 31 ', 33' (not shown on this figure) integral with the cover of the device, interconnected by a conductive bridge 34 (not shown in this figure) or a fuse and forming with the other contacts fixed 31, 33 two pairs of fixed contacts, as well as two movable contacts 35, 36 each associated with a pair of fixed contacts 31, 31 'and 33, 33' and having two positions stable, an engaged position and a triggered position.
  • Fixed contacts 31, 31 ', 33, 33 'each have a contact surface consisting of a contact pad 37 and the movable contacts 35, 36 each have two contact surfaces consisting of contact pads 38 arranged to bear against the pads contact 37 when the switching device 1 is in the engaged position.
  • Contacts mobiles 35, 36 are mounted respectively in two mobile equipments 40 identical, arranged symmetrically with respect to the axis A of said switching device 1 and mobile in translation in two opposite directions and substantially perpendicular to said axis A.
  • the control module 2 comprises in known manner a housing 20, an axis of transmission 21 connected to an operating handle (not shown) accessible to the outside of said housing and coupled by toothed pinions 22, constituting a reference angle, to a control axis 23 of the movable contacts 35, 36, arranged in the axis A and passing through the cut-off modules 3. Nevertheless, the operating handle can be directly coupled to one end of the control axis 23 according to the configuration that one wishes to give to said switching device. This assembly is possible because, as we will see later, the operating clearance is at the level of the control mechanism for the cut-off modules and no longer at the control module.
  • the control axis 23 is integral with each movable contact 35, 36 for the order simultaneously synchronously and abruptly.
  • This module of control 2 also includes a snap action device 24 by accumulation of energy, connected to said control axis 23 and arranged to cause a quick switching on and off of mobile contacts in relation to fixed contacts.
  • This snap action device 24 makes it possible, in known manner, to avoid the stagnation of electric arcs on tripping, early arcing of engagement and has a spring mounted in such a way that all intermediate positions between the on and off positions of the break are unstable.
  • the control axis 23 carries two identical cams 50 each mounted on a barrel 51 which can slide axially with respect to said axis 23. These cams 50 are pushed towards the control module 2 by means of a spring reminder 52 disposed on the control shaft 23 between a side wall of the housing 4 and the was 51 closest. Each cam 50 is arranged to cooperate with the two moving parts 40 so as to move the contacts synchronously mobile 35, 36 from their triggered position to their engaged position and vice versa.
  • FIGS. 2 to 7 partially illustrate the switching device 1 showing the parts which constitute the present invention, in different positions.
  • the parts are shown in transparency, seen from the end of the control axis 23.
  • FIGS. 3, 5 and 7, these parts are represented by perspective.
  • the parts making up said switching device 1 are almost all symmetrical about axis A.
  • the input 30 and output 32 terminals are respectively connected to the fixed contacts 31 and 33.
  • These fixed contacts 31, 33 each consist of a conductive bar bent at right angles, one of the branches being housed in the corresponding terminal and the other branch carrying a contact pad 37, for example riveted.
  • the two others fixed contacts 31 ', 33' consist of a conductive bar folded twice at an angle straight to form a stair step, one of the branches being housed in the hood of the device and the other branch carrying a contact pad 37.
  • the fixed contacts form two by two pairs of fixed contacts 31, 31 'and 33, 33' whose pads of contact 37 are arranged in perpendicular planes.
  • Fixed contacts 31 ', 33' are connected to each other either by means of a bridge forming a simple switch, or to the by means of a fuse cartridge forming a fuse switch.
  • the movable contacts 35, 36 consist of a conductive bar comprising two end branches arranged on either side of a middle branch and forming with it an angle of substantially 45 °. Each end branch carries a patch contact 38 for example riveted. Contact pads 38 of the same contact mobile are arranged in perpendicular planes and are intended to be in contact with the contact pads 37 of the corresponding pair of fixed contacts, in the engaged position.
  • the movable contacts 35, 36 are mounted respectively in the moving parts 40 arranged to move them simultaneously, so synchronous, in translation in a direction F perpendicular to a straight line passing through the two contact pads 38.
  • the angled or possibly rounded shape of the movable contacts 35, 36 as well as the moving contacts at 45 ° relative to the fixed contacts allow ensure that the pads are self-cleaning at each engagement and tripping contact 37, 38.
  • the contact pads 38 are positioned on the pads of contact 37 or move away from them according to the translational movement F which is breaks down into a horizontal component F1 and a vertical component F2, each component generating friction between the pellets 37, 38.
  • the effort maneuver G transmitted to the mobile contacts 35, 36 affects the contacts fixed 31, 33 according to the horizontal component G1 and on the fixed contacts 31 ', 33' according to the vertical component G2.
  • the angle of said maneuvering force G being 45 °, since it is parallel to the direction F, the components G1 and G2 have an equal value than G / ⁇ 2, that is to say greater than G / 2 as in the prior art. So for a same maneuvering effort, the contact effort is increased by 40%. This results in a improvement of electrical characteristics: breaking capacity and resistance to short circuits are significantly improved.
  • the particular construction of fixed and movable contacts halves the total length of copper required, which leads to a reduction in the cost price of all switching device 1.
  • the moving parts 40 each consist of a frame 41 substantially rectangular extending in the three cut-off modules and arranged in a plane inclined passing through the control axis 23.
  • This frame 41 has three windows 42 rectangular, oriented radially with respect to the control axis 23 and intended receiving the movable contacts 35, 36 of said modules.
  • the width of the windows 42 is slightly higher than that of the movable contacts 35, 36 so as to spare said operating set mentioned previously. Therefore, the frame 41 is slightly floating compared to the rest of the mechanism.
  • a return spring 43 is provided in each window 42 to maintain said movable contacts 35, 36, in their planar middle branch, bearing against said frame 41 towards the outside, that is to say distant from the control axis 23, towards the fixed contacts.
  • This frame 41 also includes two housings 44 also rectangular, intended to receive the two cams 50. On the walls opposite each housing 44 are respectively provided a drive finger 45 oriented parallel to axis A and a guide shoe 46, each cooperating with the faces opposite of the corresponding cam 50. The width of the housings 44 is approximately equal to twice that of the cams 50 thus allowing them an axial clearance D which will be detailed later.
  • This frame 41 is extended outwards by at least two transverse walls 47 arranged to slide against transverse walls corresponding 48 provided in the housing 4 of the cut-off modules 3 so as to guide said movable assembly 40 in its translational movement. Each crew mobile 40 is thus driven by its two fingers 45 guided in the two cams 50 of so as to guarantee its displacement in radial translation parallel to the axis A.
  • Each cam 50 has a barrel 51 slidably mounted on the control shaft 23 corresponding to the axial travel D mentioned above.
  • the free end of this barrel 51 has a left cam profile 53 cooperating with two lugs 54 facing each other provided respectively on the housing 4 (see Fig. 9) and the cover (not shown) of said device 1, on the side of the control module 2.
  • This cam profile 53 allows a share the mechanical coupling of two consecutive 51 drums when two 50 cams are mounted on the control shaft 23 and on the other hand the axial clearance D of said cams, the function of which will be specified later.
  • Return spring 52 (see Fig. 1) maintains this cam profile 53 in abutment on the lugs 54.
  • the cams 50 are arranged to move simultaneously, synchronously and in translation along F both moving parts 40 and comprise, for this purpose, on the side of the drive fingers 45 two non-circular grooves 55, that is to say the distance to the axis A varies in depending on the angle of rotation, these two grooves being identical and offset angularly 120 °.
  • the following detail relates to a single groove 55 cooperating with the drive finger 45 of a single mobile assembly 40 associated with a single set of movable contacts 36.

  • the bottom of the groove 55 has different reliefs defining, respectively with the internal walls 55a and external 55b, two tracks 56, 57 separate, also having the function of guiding the drive finger 45: a go track 56 for guiding finger 45 from the triggered position to the position engaged and a return track 57 to guide finger 45 from the engaged position to the triggered position.
  • the outward track 56 When switching on, i.e. to switch from the triggered position (see Fig. 2 and 3) in the engaged position (cf. Fig. 4 and 5), an effort is made to obtain operation as low as possible and to ensure good electrical contact between the mobile contacts and fixed contacts.
  • the outward track 56 therefore has two parts (see for clarity Figure 4 in which the parts are hatched): a first substantially straight portion 56a and a second circular portion 56b of small radius.
  • the race carried out by the operating handle of the switching device 1 generates a displacement proportional to the moving element 40 and therefore to the moving contacts 36.
  • the stroke performed by the operating handle causes displacement and a rapid approach of the moving element 40 having the effect of positioning very fast and tightening of the movable contacts 36 on the corresponding fixed contacts 33, 33 '.
  • the outward track 56 has a varying depth, increasing in the direction of rotation then a sudden change in level caused by a shoulder 56c.
  • the cam 50 moves axially by one value equal to the difference in depth, by relaxing the return spring 52. This axial displacement of the cam 50 has the advantage of positioning the drive finger 45 immediately on the return track 57.
  • the return track 57 therefore comprises two parts (see for clarity in FIG. 4 in which the parts are hatched): a first circular part 57a of constant radius centered on axis A and a second circular part 57b whose radius is clearly smaller than said constant radius.

  • the return track 57 has a varying depth, decreasing in the direction of rotation.
  • the cam 50 moves axially by a value equal to the difference in depth, by compressing the return spring 52. This axial displacement of the cam 50 has the advantage of positioning the drive finger 45 immediately at the starting point, in the runway 56.

Furthermore, to avoid excessive efforts on the fingers drive 45 of the moving parts 40, the axial displacement of the cams 50 induced by the relief of the outward and return tracks, is helped by the adapted cam profile 53 provided on the barrel 51. This cam profile 53 rests on the lugs 54 integral with the housing 4 and of the cover of the device 1 and helps the cams 50, in association with the spring 52, to move axially during their rotation.

  • This test position is obtained by turning the handle of said device by an angle of 60 to 90 ° in the opposite direction to that of engagement. At the time of this rotation, the moving parts 40 must not move, the switching device 1 must remain in the triggered position.
  • Each groove 55 is extended by a test track 58, framed by the internal walls 55a and external 55b, this track being circular, close to the axis of command 23, of constant radius and center the axis A and ending with a imprint 59 corresponding to the end of the drive finger 45 in the test position.
