Definitions

  • the present invention relates to a switching device according to the preamble of claim 1.
  • the main switches open first and, like the auxiliary switches are still closed, endure a practically negligible cut.
  • the auxiliary switches support most of the shutdown and, being less well sized for this function, alter the service life of the device.
  • the invention aims to provide a switching device operating as described above on closing, but reversing the switching sequence of the contact parts of the main and auxiliary switches during opening, in order to to ensure with certainty the transfer of the current flow from the auxiliary switches to the main switches.
  • the invention provides a switching device comprising at least one main switch which can pass from an open position to a closed position during a transient closing phase and from a closed position to an open position. during a transient opening phase, these two phases being controlled by respective movements of a control member, and at least one auxiliary switch comprising at least one fixed contact and one movable contact connected to said control member by the 'through a mechanical connection.
  • this device is characterized in that said mechanical connection comprises a disengageable coupling designed so as to pass from a coupled position to a uncoupled position, during the transient closing phase by closing the auxiliary switch before close the main switch and by opening the auxiliary switch after closing the main switch, and then return from said uncoupled position to the coupled position, during a subsequent passage of the main switch through the other transitional phase.
  • the above-mentioned disengageable coupling is of the stress-breaking type and is designed so as to obtain a disengagement when the control force transmitted to the auxiliary switch by the control member of the main switch, exceeds a predetermined threshold.
  • the above disengageable coupling consists of elastic snap-fastening means.
  • the disengageable coupling uses at least two parts magnetically coupled to one another.
  • the auxiliary switch and the return spring which is associated with it are arranged in a housing independent of the body of a contactor device. comprising the main switch, an armature return spring, as well as the electromagnet to which the actuation function of the two types of switches will be assigned.
  • a circuit 1 for connecting a capacitive load 2 formed by three capacitors - C1, C2, C3 - to a three-phase network - R, S, T - is shown in Figure 1.
  • a type of remote-controlled device shown in this figure by way of example for making this connection calls, on the one hand, for an electromagnetic contactor device 3 having in an enclosure 26 an electromagnet 4, a movable armature 5, a return spring 5 ′ which tends to place the latter in a rest position, and a control member 6 which may advantageously be constituted by an insulating rake or contact carrier on which are arranged moving parts of a set of switches main three-pole 7, 8, 9; on the other hand, a housing 11, which is mechanically associated with the housing 26, comprises a set of auxiliary switches 13, 14, 15 which is actuated by a second control member 12 which can also be produced in the form of a rake or insulating contact carrier, and being subjected to the action of a clean return spring 12 ′ whose effects tend to open these switches.
  • the two control members which are advantageously but not necessarily arranged in alignment here, are coupled to each other using a releasable coupling 20, the operation of which will be specified below.
  • auxiliary switches 13, 14, 15 are placed in series with respective limiting resistors - R1, R2, R3 - each of these series assemblies being placed in parallel on a corresponding main switch 9, 8, 7.
  • Each resistor R1 can be split into two series resistors R1a, R1b placed on either side of the corresponding auxiliary switch 13; the resistors which are here placed outside the boxes 26, 11 are advantageously connected to the external terminals of the switches using their connection conductors so that good heat dissipation takes place and the manufacturer is not led to modify the conventional boxes it has to receive the contactor and the auxiliary contact block, see figure 1.
  • any movement of the first in direction F will cause the moment of excitation of the electromagnet simultaneous displacement of the second.
  • This closing which is carried out a few milliseconds before that of the main switches and which only authorizes the passage of reduced initial currents through the three resistors, is obtained thanks to a difference in the closing distances specific to the contact parts of the main switches - e2 - and auxiliaries - e1 -, the latter being more reduced.
  • This difference in stroke is used here so that an automatic disengagement of the coupling 20 and therefore of the two contact carriers occurs, thus making it possible to release the auxiliary contact carrier and allowing it to return to its rest position when the carrier - main contact has already closed the corresponding switches.
  • a first type of removable coupling 20, visible in FIG. 3 in the coupled state when the complete device is at rest, uses simple mechanical means which can be molded or overmolded during manufacture, or which can, on the contrary, make subject to a combination of appropriate spare parts.
  • An extension 16 of the contact carrier 6 which passes through an opening 27 of the housing 26 of the contactor and is projecting relative to a face (for example a front face or a side face) 30 thereof, has a clearance 28 of which the opposite edges 24, 24 ′ are narrower at the entrance than the transverse dimension of a housing 29 which follows it.
  • the contact carrier 12 of the auxiliary contact box 11 has for its part a fork-shaped extension 19 with elastic branches 17, 18 whose ends 17 ′, 18 ′ of the elastic branches 17, 18 are wider than the portion which precedes.
  • the elasticity of this fork allows it to be released from the housing when sufficient longitudinal traction is exerted between the two contact carriers, and allows it to engage therein when a longitudinal thrust is exerted by the contact carrier 6 towards the contact carrier 12.
  • a de-excitation of the electromagnet of the contactor which allows the contact carrier 6 to return to its rest position - in direction G - thanks to the return spring 5 ′ brings the edges of the clearance 28 in contact with the fork 19 by communicating to the latter by percussion a transverse pinch which allows it to penetrate with sliding in the housing 29, so that the clutch of the coupling 20 is again re-established pending a new operating cycle, see FIG. 2.
  • the means which have just been described give their full effectiveness only if the shape of the attraction curve of the electromagnet has been judiciously chosen so that the slowdowns caused, on the one hand, by the expenditure of energy required to disengage the coupling 20 and, on the other hand, by the compression of the spring 12 ′ are not too great.
  • the energy developed by the relaxation of the return spring 5 ′ of the armature must be sufficient so that the penetration of the fork into the housing is ensured regardless of the orientation that the device takes in space. .
  • the two contact carriers 38, 39 are associated by calling on the adhesion of magnetized 37 and magnetizable 36 parts for example using a ferrite and soft iron.
  • the magnetizable part and the permanent magnet may be placed on one or the other of the contact carriers.
