Definitions

  • the invention relates to an electromagnetic switching device comprising a base, the base of which is fixed to a wall and in a cavity of which is arranged a control electromagnet having a movable armature capable of actuating, using detachable coupling means, a transmission part connected to a movable single-switch switch contact located in an insulating housing provided with opposite input and output terminals, this housing being removably associated with a fixing surface from the base opposite the base.
  • Such an apparatus which can be implemented in all current distribution systems, can, depending on the embodiment of its controlled switch (es), establish either closures and repeated openings of a power supply circuit.
  • a load either still and in combination with devices sensitive to overloads or current failure, establish automatic circuit openings to protect the lines and / or the load.
  • a known device such as that illustrated by French patent No. 2 257 141 of the Applicant, and whose general constitution recalls that which is mentioned above, is solely assigned to the function of contactor.
  • a circuit breaker device is also known which is illustrated, for example, by French patent No. 2,573,571 of the Applicant, where a moving part of a single-break switch can be actuated either by a remote control electromagnet housed in a base, or even be opened by repulsion forces developed during the appearance of short-circuit currents.
  • this switch In a first contactor-type regime, this switch must be able to retain its mechanical and electrical properties at a relatively high temperature which is developed by the frequent passage of currents ranging from the nominal current to ten times this, while, in a type circuit breaker for which this switch will be rarely requested, the energy to be dissipated in the housing when cutting very high currents, will be much greater; in both cases, conditions for good residual isolation after the execution of a number of specific maneuvers must be guaranteed in comparable ways.
  • the present invention therefore proposes to provide an electrical switching device whose constitution responds to that mentioned in the introduction and in which measures will be taken so that one can quickly and without error, associate with a standard base and separate from it without intervention on the corresponding conductors, switch modules having various functions, while making each complete appliance benefit from good quality insulation.
  • the aim is achieved thanks to the fact that: - the fixing surface delimits a closed cavity of the base, with the exception of openings located opposite a coupling piece linked to a movable frame parallel to this face to allow the passage of ends of transmission levers insulators which are pivoted in the removable contact box, and which operate the tilting of movable contact levers extending between connecting conductors placed in the vicinity of this fixing face and to which they are connected, while fixed contact supports are placed parallel to the vicinity of an outer face of the housing.
  • the base further having connection terminals which permanently receive external conductors of the circuit, and which are connected to contact parts cooperating elastically with corresponding parts secured to the removable housing and connected to the switches.
  • An electrical switching device 1 visible in FIG. 1, comprises a base 2 having: a base 3 for hooking it against a wall 4, an opposite fixing or receiving face 5, two sets of opposite terminals 6, 7 which are intended to be connected, for example by means of screws 8, respectively 9, to a supply line 10 and to a load line 11, and which are arranged substantially at the level of the fixing face, and a closed cavity 12 opening towards this face in the illustrated embodiment.
  • An electromagnet 13 which is disposed in this cavity, comprises in a known manner, a fixed yoke 14, a coil carcass 15 and an excitation winding 16 for attracting a movable armature 17 and / or a plunger core 18, which are biased by a return spring 19 to a rest position - R -; this armature moves along a translation axis XX ⁇ substantially parallel to the fixing face depending on whether the winding is or is not excited thanks to control terminals which are connected to it, but which are not shown on this figure.
  • This electromagnet can be of the monostable or bistable type and can use one or more permanent magnets if it is desired that its changes of states be made using current pulses; in the latter case, one can dispense with the use of a return spring.
  • the cavity 12 is mainly closed by a cover 20 which is placed in the plane of the face 5 which is made soli daire of the base 2, and which has a set of openings 21 of which only one 21 r is visible. These openings are placed opposite a separable coupling piece 22 which is itself integral with the frame and which has, for example, a set of housings 23 of which only one 23 r is visible; these housings are placed opposite the corresponding openings 23.
  • An insulating switch box 30 is removably associated with this base, on the one hand, by mechanical fixing means, such as for example screws 31 going to a threaded hole in this base and, on the other hand, thanks to removable electrical connection means such as two sets of conductive knives 32, 33, two of which 32 r , 33 r are visible in this figure.
  • these knives are projecting relative to a bearing face 34 of the housing 30 and are inserted in sets of elastic current sockets 35, 36 of which only two 35 r and 36 r are visible; these sockets, which are electrically connected to the neighboring connection terminals, are preferably mechanically fixed by the latter.
  • a set 40 of electrical switches the number of which is equal to that of the set of terminals.
  • a particular switch such as 50 which is only visible in this figure, comprises a fixed conductive support piece 41 on an internal end 42 of which is disposed a fixed contact 43, while the other opposite external end represents the knife 33 r ; this room has a large portion 44 a which runs parallel to an external face 45 of the housing in an insulated groove 41 a , and a bent portion 44 b passing in the vicinity of a terminal 9.
  • a second conductive part 46 of which an external end represents the knife 32 r , comprises a large portion 47 which circulates parallel to the support face 34 and to its vicinity as well as an opposite internal end 48 which is connected by a flexible conductor or braid 49 to a movable contact lever 51.
  • an insulating transmission lever 60 having, for example, a hub in the form of a yoke 57, oscillating in turn on the pivot 53 and an arm 58 which passes through an opening 65 of the face 34 so that its end 56 comes to engage in the housing 23;
  • this arm which circulates in a direction substantially perpendicular to that of the arm of the lever 51, passes in the vicinity of a remote portion 48 of the conductor 46 and comprises at this level a yoke bottom 59 intended to receive a first end 61 of a compression spring 62 developing the contact pressure, while the other end 63 presses on the lever 51 to impart to it a torque of direction suitable for exerting pressure from the movable contact 55 against the fixed contact 43.
  • the present arrangement is advantageous insofar as the conductor 46 and the contact lever 51 which are at the same potential, and where the path of this conductor clears a space 66 capable of receiving fins of frac operation of an arc chamber for the electric arcs, while the ends of the portions of the conductor 44 a , 44 b which are bent, form with the braid 49 and the lever 51 a current loop favoring the displacements of these arcs towards this room ; these advantages are obtained here in a limited overall switch volume.
  • the switch box 30 a consists of an insulating envelope 70 in which are arranged, for example, three insulated cells 73, 74, 75, which are open towards the support face 34 and which each receive an insulated switch cartridge such as 81, 82, 83, see FIG. 5.
  • Each of these cartridges contains the elements of a switch as described above, but this this is then incorporated in a particular closed case 84 which is able to cooperate with snap-on retention means such as 76, 77 carried by the envelope 70, see FIG. 5.
  • the screws 7 and 6 of the supply terminals 9 and 8 are arranged between the base 2 and external flanges 88, 85 of the housing 30, which are drilled with holes such as 86, 87 to give access to a screwdriver; these edges can limit the movement of the screw heads by covering them in order to make them captive and to isolate them from the outside.
  • connection terminals 80, 90 or connection 95 during service see Figures 7 and 8, and to protect them as a whole against any external contact
  • these terminals can be placed, isolated by partitions 64, 65, in housings of a base 2 a such as 67, 89, 91 which are located under the plane WW 'of the fixing face 5 a , see figure 7; flanges 92, 93, 94 which protect the screws of these terminals can, if necessary, be arranged on the opposite ends of a particular contact cartridge 81 a , see FIG. 8.
  • the housing 130 here contains a movable contact lever 151 which is associated with the insulating transmission lever 160 by means of an exhaust device 110 using the contact pressure spring 162.
  • a free end 124 of the lock has an eccentric boss 125 which meets a tangential extension 113 of the lever 151 placed between its ends, and which communicates therewith a torque clockwise to communicate a contact pressure to the movable contact 155; the switch 150 comprising the two contacts 143, 155 is placed in the vicinity of a first arcing chamber 66 a which will be swept by the movable contact, moving counterclockwise.
  • a conductive braid 148 connects a conductive part 147 to a central region 152 of the lever 151 which can cooperate with a stop 160 a of the yoke 157.
  • This fixed contact 143 is here carried by a fixed conductive part 144 c of which a first end 142 joins a second arc chamber 166 b , while a second folded end of this part joins a coil 78, with an axis substantially parallel to the bearing surface 134, the center of which is occupied by a magnetizable core or striker 79; the winding and the striker core constitute one of the fault current detectors 52 which can be incorporated in the housing and associated with the internal circuit of the device.
  • a second conductor 144 a parallel to the lever 151 and connected to the winding is extended by a portion 144 b bent at 90 °, which joins a connection end or plug or knife 133.
  • the conductive parts 144 c , 78 and 144 a circulate in the vicinity of a front face 145 of the housing 130.
  • the energy developed by the magnetic overcurrent detection device 52 comprising the coil 78 and the striker 79 is used here to directly cause an opening forced contact 155.
  • This opening which must occur when the striker is attracted very quickly, implements a percussion lever 96 which oscillates around the housing pivot 98 common to a manual operating member 97, and which is coupled at the end 79 a of the striker.
  • the free movable end 96 a of the percussion lever drives, for its directional movements G, an insulating screen 99, one end 99 b of which can move parallel to the lever 151, being inserted between the two contacts 143, 155 as soon as they these are separate.
  • the insulating screen remains stationary and the operation is in all respects comparable to that of the previous device.
  • the automatic opening of the switch 150 makes use, in this case, essentially of the repulsion forces which are developed between the conductor represented by the lever 151 and the conductive parts 144 c , 144 a which are parallel to it and which are used in a mechanical device with a trigger threshold 105.
  • the spring 162 is compressed by the cross member 120 due to the force applied by the extension 133 to the boss 125 of the latch 121.
  • the supply circuit 146 of the coil 16 may include a safety switch 140 which is placed in series with the latter, and which is open when the striker 79 is attracted in direction G by the coil 78, see Figure 13.
  • a safety switch 140 which is placed in series with the latter, and which is open when the striker 79 is attracted in direction G by the coil 78, see Figure 13.
  • Such an arrangement naturally implies the presence of plugs or interconnection knives 137, 138 on the housing 130 a and additional sockets 135, 136 on the base 102 d when the safety switch is placed in the housing 130 a ; this base here also carries control terminals 16 a , 16 b for operating the external supply of the circuit of the coil 16.
  • the return to service of the device requires that the screen returns to its original position, an operation which is established by manual intervention on the member 97 and counterclockwise.
  • programmable mechanical indexing means are arranged on the fixing face of the base, for example on a reversible cover 108, closing the cavity 12 f , see FIG. 14.
  • This cover may, for example, have on each opposite face 108 a , 108 b one or more fingers or projections, such that 109, respectively 110, the arrangement of which on the fixing face 5b can be modified, on the one hand, thanks to a pivoting of 180 ° C in its plane and, on the other hand, thanks to a reversal; in this way, we can specialize four functions of switch boxes I, II, III, IV each having specific notches such as 114.
  • the cover can also cover the connection sockets 35, 36 and / or the connection terminals 6, 7 to ensure their protection when the switch housing is separated from the base, see FIG. 15.
  • each of the cavities such as 12, 12 b , 12 f one or more auxiliary switches, such as that represented by dotted lines by 127, including the signaling terminals 128, 129 are accessible on the housing 102 d .
  • the movable armature 172 is constituted by a system of magnetizable parts and magnets 173, 174, 175 substantially parallel to the axis - ⁇ - of the coil 176 and moving outside of it in this direction, see FIG. 16, it may be advantageous to place this mobile system on the side of the fixing face 177 of the base 178, and to provide it with a hook 179, by salient example, intended to avoid dangerous separations and engagements of the housing, for which means have already been proposed in FIGS. 2 and 3; this hook cooperates here in the working position - T - with a bent notch 180 of the removable housing 181 whose profile prevents separation, while the dimensions of the notch prevent engagement.
