Definitions

  • the invention relates to the protection of contactors against the effects of contact separation due to repulsion forces between them.
  • a contactor is normally provided to support effective currents of the order of 12 In (or 6 In, depending on the ratings), In being the nominal current. Beyond this value, there is a risk of soldering and, at least, of contact wear, caused by various effects which will be analyzed below.
  • Overloading can occur either when the contactor is closed or during its closing. If it corresponds to currents which would exceed, in the absence of rapid protection means, for example 100 In, the action of the switch member is very rapid, that is to say that the current which flows in the main contactor of the contactor reaches for example 40 to 50 In peak and then drops back to the value 0, in a time, of the order of 2 ms for example, much less than the duration of a half-wave of the sector.
  • the switch member does not exert any action of significant limitation of the current during half-wave and, consequently, a current greater than 6 In or 12 In can pass through the contactor.
  • the repulsive forces then manifest themselves in the vicinity of the crest of the current and, as they are much weaker than in the previous case, when they cease, the contact closes again on a still large current. This results in a significant risk of welding.
  • the invention proposes to compensate, during the time interval separating the appearance of the overload and the opening of the circuit, the effect of the repulsive forces of electro-dynamic nature which arise between the fixed and mobile contacts d '' a contactor, in order to prevent the contacts from being able to separate inadvertently with the consequences which would ensue (wear, risk of welding) for certain values of the overload current.
  • a contactor comprising, in a known manner, in particular by patents USA-3 123 691 and FR-A-1 514 069, a control electromagnet having a movable part, a contact assembly comprising at least a first conductive support piece of at least one movable contact and at least a second conductive support piece of at least one fixed contact, connecting members between the movable part of the electromagnet and the first contact support piece mobile, an elastic member arranged to cooperate with said first movable contact support part in a direction which establishes a certain contact pressure, and means for locally concentrating the flux created by the flow of current in said conductive parts in the vicinity of said first conductive part, to exert thereon a first force of attraction which tends to cause the closure of the contacts.
  • this contactor is more particularly characterized in that said means comprise at least one first soft magnetic part rigidly coupled to a contact carrier secured to said movable part of the element.
  • the compensation device does not contribute in a appreciable manner to modifying the contact pressure, which it only effectively reinforces when an overload develops forces. of notable repulsion.
  • the contact pressure is therefore provided, in the traditional way, by a pressure spring associated with the support of the movable contacts of the contactor.
  • said first magnetic part has the shape of a U the base of which is rigidly coupled to a contact carrier secured to the movable part of the electromagnet, while the second magnetic part is arranged to form a variable air gap with the upper ends of the branches of the U and that said part of the support conductor of the movable contacts has the form of a blade on which said second part is supported and engaging in the opening of the U by forming a narrow air gap.
  • the magnetic part indirectly coupled to the mobile part of the electromagnet has the shape of a U and said part of the conductive support of the mobile contacts has the shape of a blade which engages in the opening of the U by forming a narrow air gap.
  • said second magnetic piece is held in abutment by said contact pressure spring associated with the conductive support of the movable contacts on said part of said support and forms a variable air gap with said first magnetic piece.
  • a contact holder comprising an insulating part or contact holder 1 secured to the frame of an electromagnet, not shown, and two fixed contacts 20a-20b carried by conductors folded in "J" 2a-2b cooperating with a movable contact bridge 3 with two branches 3a-3b respectively carrying contact pads 30a-30b, on either side of a vertical blade 3c.
  • a contact pressure spring 4 is housed in a blade of non-magnetic material folded into a U, the lower part of which is arranged so that it can slide inside the part 1, and the upper part of which leaves the part. 1, is provided in the vicinity of its ends with two windows 50-51.
  • a U-shaped piece of soft magnetic material 6 is placed between the branches of the blade 5, in their upper part, and fixed at its base to the piece 1 by means of a pin 7.
  • the spring 4 is pressed, at one end, against the underside of the part 6 and, at its other end, against the base of the part 5.
  • the part 1 When, the armature being attracted, the part 1 is driven downwards (arrow F, FIG. 2), the part 6, secured to the part 1 by the pin 7, moves the same distance a.
  • the spring 4, by pressing the bottom of the blade 5, drives the latter down over a smaller distance b, which corresponds to the distance between the pellets 20a and 30a on the one hand, 20b and 30b on the other hand .
  • the blade 5 drives the part 8 and the bridge 3, until the contacts are closed. At this time, the blade 5 can no longer move and, the part 6 continuing to descend, the spring 4 is compressed, thus ensuring a certain contact pressure and sufficient for nominal operation.
  • the arrangement and dimensioning is such that, for current intensities of the order of the nominal value ln, the vector sum of the attractive forces, and of the opposite electro-dynamic forces developed in the conductors folded in "J" , is practically negligible and the contact pressure is only ensured by the spring.
  • the part 6 will exert, for a closure on a peak current corresponding to an overload, a reaction on the armature in the form of a tensile force tending to tear the armature from the electromagnet. It is therefore important that measures are taken to prevent the armature from becoming detached from the fixed yoke of the electromagnet. To this end, it is advantageous to supply the electromagnet with rectified current during the holding period: the attraction force then never passing through the zero value, the risk of the armature tearing off is reduced. This measure may or may not be combined with a relatively large dimensioning of the electromagnet.
  • the additional holding force also has the effect of reducing the phenomenon of mechanical bounce of the contacts which manifests itself during closing, and therefore of reducing wear, starting from around 8 ln.
  • a piece 10 of soft magnetic material provided at its base with a double hooking tongue 101 which engages between two suitably profiled projections 90-91 of the internal wall of the part 9.
  • the part 10 has a U-shaped cross section and the double-cut movable contact bridge 11, which carries the two contact pads 110a-110b, has a central blade 110c, which engages in the U as shown in the figure 8.
  • the fixed contacts 120a and 120b are carried here by rectilinear blades 12a, 12b.
  • the piece 9 is provided, at its upper end, with a hoop 92 to which is fixed, by hooking complementary profiled parts, a piece of insulating material 13 provided with a central stud 130 by which one end of a spring is guided of pressure 14.
  • the other end of the spring cooperates with a recess 150 which is provided with an insulating part 15 which is supported, by its ends 151-152, on the two respective branches of the movable contact bridge 11.
  • the fixed contacts 12a-120a, 12b-120b are rectilinear as in that of Figures 6 to 10 and the insulating part 9, integral with the armature of the electromagnet, cooperates at its upper part with an insulating part 13 identical to that of FIGS. 6 to 10 and also serving to guide and support one end of the spring 14.
  • the latter bears, at its other end, on an insulating part 16 which itself supports, by its central triangular projecting part 160, on a first blade 17 of soft magnetic material, which in turn presses on a movable contact blade 18, provided with contacts 180a-180b.
  • a second blade 19 made of soft magnetic material is fixed, for example by means of a bolt 190, to the lower part of the part 9.
  • the part 19 separates from the parts 17-18 and, the part 13 undergoing the same displacement, greater than the distance between the contacts , the spring 14 which pressed the part 18 on the part 19 until the establishment of the contacts, is then compressed by an additional quantity to ensure the contact pressure.
  • the device could be applied to assemblies with single breaking contacts.
  • the shape and arrangement of the magnetic piece or pieces could be subject to variants, as well as those of the contact assembly itself.
  • the active air gaps are defined by the slot of the U.
  • parts corresponding to those referenced by 17, 18, 19 could have flat or rectilinear shapes, means not described, but obvious to those skilled in the art, moreover making it possible to ensure lateral support of the contact bridge and of the ferromagnetic parts.
  • Such an arrangement is therefore particularly advantageous due to the fact that it is much easier to manufacture a circuit breaker or a limiting stage, which is able to effectively limit the peak currents mentioned above, while it is very difficult to limit the peak currents of the order of 15 to 20 ln for which the faults of traditional contactors appear precisely.
