Definitions

  • the invention relates to the extinction of the electric arc which arises when a circuit is opened by a switch device, operating on direct or alternating current.
  • low and medium voltage breaking devices ranging for example from 110 V to 5 KV
  • the discharge occurs in the air and more especially, those in which an electrically insulating screen is interposed between the contacts in order to favor the rapid extinction of the arc and to avoid its re-ignition.
  • limiters where the separation of the contacts is for example obtained by means of electrodynamic repulsion forces which are exerted in conductive portions of contact support when the current which crosses them exceeds a predetermined threshold
  • circuit breakers where contact separation is achieved by releasing accumulated mechanical energy or by magnetic energy developed by the short circuit, and even some contactors.
  • the screen subjected to a translation perpendicular to the direction of spacing of the contacts, does not come between the contact pads until after they have been separated from each other by the cooperation, with their support blades, of bosses with which it is provided.
  • the means for opening the contacts merges here with the means for propelling the screen and the latter must completely overcome the pressure for maintaining the contacts in the closed state. It necessarily follows that the interposition on the path of the arc of the screen thus braked in its translation occurs after a relatively long time, so that the arc will have had time to stabilize.
  • a blowing coil is also arranged in the vicinity of the contact pads to drive the arc thus formed towards a slot into which the edge of the screen penetrates.
  • the substantially complete shearing of the arc before it has had time to stabilize is obtained by controlling a sufficiently rapid movement of the screen by means of a member separate from the control member of separating the contacts and arranging the cooperating surfaces of the terminal edge of the screen and the wall insulating so that a substantially complete seal is obtained between them when the screen has come into abutment position against said wall.
  • the linear speed of movement of the screen is greater than 2m / s.
  • the screen is guided in its movement by a groove arranged to provide a lateral seal.
  • FIG. 1 to 4 there is shown a switch device comprising, housed in a housing 1, two contact supports 2 and 3 provided with contact pads 201 and 301 and able to pivot around two points 202-202 '. The latter is connected to a conductor 303 which leads to a connection terminal 304. A coil 4 is supplied from a connection terminal 204.
  • contact opening control lock 2-201 and 3-301.
  • these means will respond for example to a predetermined current overcurrent, corresponding to a short circuit and may be of different known types: thermal response members such as bimetallic strips, electromagnetic response members such as coils or electrodynamic response (repulsive forces exerted between the conductive supports of the contacts).
  • the front edge 601 of this screen is located a short distance dl behind the point of contact.
  • This screen is propelled forward by means which have been symbolized here by the coil 4 and a system of levers 401-402 connected to a plunger core 403 with which it is provided.
  • These means are, in the illustrated example, electromagnetic and actuated by the effect of the short-circuit current. However, they could be of various types: for example, armed spring triggered at the desired moment, or others.
  • these propellant means must be capable of communicating on the screen a considerable translation speed, at least equal to 2 m / s and which will often, in practice, be of the order of 10 to 20 m / s , as will be explained below.
  • the slot 603 communicates with the outside.
  • degassing means such as baffles 604 and channels 605 forming expansion chambers 606.
  • the distance d 2 between the point of contact of the pellets and the bottom of the slot is relatively small, so that the path of the arc which forms between the pellets is not considerably extended when the screen pushes it towards the slot.
  • the essential phenomenon is that the arc is completely sheared without ever having had time to stabilize and experience shows that this results in a growth of the arc voltage as brutal as that which occurs in a fuse, therefore an extremely rapid extinction and a considerable reduction (by a factor given as an indication of the order of 2 to 3) of the energy of the arc compared to what happens in the absence of this phenomenon of abrupt reduction of the section S of the arc to a practically zero value.
  • the front edge of the screen must have reached the appropriate speed when it touches the arc: this is why the distance d l mentioned above must have an appropriate value.
  • Another essential condition for producing the critical phenomenon of very rapid extinction of the arc by complete shear is that no escape route is offered to it; hence the importance of the sealing arrangements and low lateral clearance mentioned above.
  • the screen completely isolates the contact supports from one another, thus eliminating any risk of welding: this function of the screen is previously known.
  • the screen cannot be metallized by the arc and, consequently, the performance of the device will not be degraded by repetitive cuts. Such a device can thus be used even in contactors.
  • the degassing means are obviously intended to prevent an excessive increase in the pressure inside the arc chamber.
  • the device described can be the subject of very diverse applications and present a very wide variety of embodiments.
  • the receiving slot of the front edge of the screen may be eliminated in certain cases, the screen then abutting against a flat surface or otherwise shaped to ensure adequate mechanical contact, with sealing between the screen edge and said surface. Note, however, that the use of a slot, associated with degassing means, prevents the rebound of the screen which arrives at high speed on the wall.
  • the screen can receive different profiles and, for example, include, at its front edge, a blade of thinner thickness which extends it and comes into the slot.
  • Said blade can be located in the longitudinal plane of symmetry of the screen, as shown in FIG. 5, where there has been shown such a median blade, 607 on the lateral faces of which the contact pads 201 and 301 are in support in the closed state of the switch: the contact is then ensured by a conductive pad 608 incorporated in the blade 607. The cut is made when this pad has moved relative to the pads 201 and 301.
  • the device of Figure 5 also includes the same members, not shown, as that of Figures 1 to 4 and the contact supports 2 and 3 are pivotable.
  • FIG 22 there is shown a screen 6 in the form of a cylindrical crown guided by an insulating cylindrical column 6081 in which is embedded a fixed contact 3 which leads to a surface conductive pad 6080 in the form of a ring.
  • the front end of this column is integral with the wall 102 of the housing surrounded by a groove 1023 into which penetrates the front edge of the screen 6 when the latter is propelled by means not shown, at the time of pivoting of a movable contact 2 which deviates from the range 6080.
  • the screen 6 thus completely separates the two contacts from one another and the arc is throttled inside the groove 1023.
  • the latter communicates with degassing channels 605 on each side of the column 6081.
  • the blade 607a extends the base of the thick body of the screen and thus forms a stair step which enters the slot 603 and abuts (by the surface 6072a) against the wall 102 as indicated above.
  • the conductive pad 608a embedded in the blade is then connected to an electrical connection 609 embedded in the screen, to constitute the fixed contact.
  • the degassing channels are designated by 610.
  • the contact 2 pivots upwards while the pellet 608a undergoes a translation and is received in the slot 611.
  • FIG. 10 and 11 schematically illustrate an embodiment of the device of Figures 7 to 9, where the terminal part of the screen has a portion of smaller thickness 613 connected to the main body by an inclined ramp 614. This arrangement improves the shearing of the arc, the main body of the screen and the ramp then ensuring its stopping and the shoulder 6120 of FIG. 9 is unnecessary here.
  • a single screen, movable in translation parallel to the contact supports in their rest position and cooperating with an insulating surface shears the arc by shearing perpendicular to its natural path, or more or less oblique to said path, but, in any case, not tangential.
  • This same type of shearing can be obtained with completely different structures of the screen and the insulating surface and different movements of a translation.
  • FIG. 12 to 14 a device comprising two screens 6a and 6b movable in translation relative to the housing 1 and whose opposite end portions have a complementary shape, so that the front edge of the thin screen 6b will come, at the end of the open position of the pivoting contacts 2-3, engage to the bottom of the narrow open housing 600a of the screen 6a.
  • the contacts 2 and 3 are separated and arranged on either side of the end of the two terminal portions, nested one inside the other, of the two screens, so well that the housing is divided into two sealed chambers with respect to one another (the screens sliding, for this purpose, in appropriate grooves in the housing).
  • a means of propelling the screens comprising two pivoting levers 601a and 601b, normally returned to the separated position by respective springs 602a and 602b and which approach each other under the action of two magnetic cores 603a, 603b controlled by a coil 625, until they come into contact with each other.
  • At least one of the contacts is pivotable or moves away elastically to let the screen pass.
  • FIGS. 15 and 16 show a comb screen structure intended to be interposed between fixed contacts such as 20-21 and contacts such as 30-31 movable by translation perpendicular to the screen.
  • This structure makes it possible to produce devices with multiple contact couples (mobile contact bridge 3).
  • Each tooth of the comb that forms the screen is guided by its lateral edges in grooves such as 622-623 formed in partitions arranged in the housing 1.
  • the bottom of the intervals 624 between fingers stops the screen by abutting against narrow parts 100 of these partitions.
  • FIGS. 17 and 18 An axis 616 whose ends rotate in two walls of the housing 1 supports a stirrup 617 whose legs 6170-6171 carry a screen 6 in the form of a portion of cylindrical crown capable of moving in a groove 620 the bottom of which communicates with the outside via vents such as 621.
  • the propulsion of the assembly is ensured by a spring hairspring 619 pre-armed and triggered by means symbolically shown at 40.
  • the movable contact 22 is pivotally mounted about an axis 220 parallel to the axis 616 and which also pivots in two _walls of the housing. The end of the contact 22 enters the groove when the screen is in the rest position to come, in the closed position shown, in contact with the fixed contact 3.
  • FIGs 19 to 21 there is shown a device composed of two screens 6c and 6d which is interposed between two contacts 2 and 3, which, when the complete device is opened, (not shown) move apart. one of the other perpendicular to the screens.
  • Each screen has two integral parts, each a little smaller than a semicircle, namely an external part and a base. The latter has a pivot axis, such as 6000a, fixed to the housing, not shown, of the device.
  • a ring 40 itself mounted in the housing so as to be able to turn on itself when it is actuated by a non-illustrated propellant means, comprises two diametrically opposed pins 401 and 402 which are respectively engaged in notches 403 and 404 contained in the respective external parts of the two screens.
  • the rotation of the ring therefore has the effect of rotating each of the two screens around an eccentric fixed axis.
