Definitions

  • the present invention relates to a device with at least one moving contact for line protection device, for example of the type circuit breaker and / or differential device, etc. It is therefore in the field of devices conventionally interposed on at least one power line and ensuring the protection of downstream installations of said device.
  • these protection devices comprise a fixed contact and a movable contact disposed between connection means of the line.
  • the movable contact which must have a certain amplitude of displacement, generally takes the form of a rotating arm at the free end of which is fixed a contact pad, said arm being able to pivot between a closed position resting on a pad of the fixed contact, and an open position at a distance therefrom.
  • the function of the protection device is to very quickly separate the moving contact from the fixed contact and open the door. line so as not to damage the devices and devices constituting the circuit to be protected.
  • these protection devices comprise a movable contact carrier (s) connected to a control lever of the position of each movable contact via a mechanical lock which echoes the positions of the joystick in contact and vice versa lock which can also be actuated by means of detecting short circuits or current overloads in the direction of an opening of the contacts. The lock then actuates the contact carrier (s) and the movable contact (s) to proceed with the opening.
  • These protective devices can be monopolar or multipolar, and in particular three-phase.
  • the contact carrier (s) manages the movement of all the mobile contacts equipping the protection device, the number of which corresponds in practice to that of the protected lines.
  • the movable contacts are not attached to the contact carrier (s) in a blocking manner, since there must be a controlled rotational movement of one relative to the other to provide the contact force to the closing contacts.
  • Each movable contact is therefore connected to the contact carrier (s) by means of a hinge mechanism comprising at least one torsion spring.
  • This mechanism must also ensure the pivoting of the assembly contact-contact (s) / contact (s) mobile (s) for the opening of the line and the double electrical and mechanical link, permanent, each mobile contact to a device connection to the circuit to be protected. It is thus necessary to manage the double constraint of this permanent link which implies a mechanical contact for the passage of the electrical current and to keep the mobile character of the contact.
  • this latter link is upstream or at the level of short circuit detection means or current overload, and it must therefore take a form for cooperation with these means.
  • said connection is not made by means of a flexible conductive braiding according to a possibility commonly used in the prior art, but via a solid connection to a degree of freedom (rotation) comprising a fixed support relative to the housing of the device which allows on the one hand the pivoting of each movable contact arm in a connection for the passage of current, and secondly the connection to the protected line.
  • the contact carrier (s) The existence of relative rotations between the contact carrier (s) and the arms of the movable contacts requires the contact carrier (s) to have a geometry of circular shape which exceeds the parts of the components organizing the connection with the rest of the line.
  • the housing of the contact carrier (s) are cylindrical, having an opening for the introduction of the hinge mechanism, comprising the movable contact, the rotation shaft or the like, the spiral spring or springs and the arm pivoting support.
  • These components are further assembled into a so-called manipulable hinge subassembly as such, and which is of symmetrical shape with respect to a longitudinal median plane of the movable contact arm, as well as the housing themselves.
  • the housings which have been shown to allow the relative rotation of the various components to be used, must therefore also allow correct supports for the springs, so that they can exercise their twofold function of torsion and compression.
  • the difficulty in this type of configuration, is to ensure easy assembly, and then maintaining in position the hinge subassemblies in the housing without detriment to the pivoting arms or the operation of the springs.
  • each housing has rectilinear grooves made in side walls of the housing substantially perpendicular to the pivot axis and opening into the opening, for housing and guiding the ends of the shaft with a functional clearance
  • the springs have a substantially rectilinear end intended to bear against an inner face of the housing, constituting the sole bearing zone of the springs on the contact carrier ( s), and a bent end provided to catch on a lug protruding towards a side wall of the end of the movable contact disposed in the housing, said lug being located on the side opposite to that of the arm relative to the pivot axis.
  • the balance of the torsion springs is always ensured by three point supports which are distributed as follows: a support on each of their end legs, and a third support at the interior of the body spring, for example on a central axis.
  • the third support can be performed on the outside of the spring body, in practice in the housing in which it is inserted.
  • the central part constituting the body of the spring is never in contact with either the central shaft or the bottom of the housing of the contact carrier (s).
  • the double contact at the tab protruding from the arm of the movable contact is such that the support is no longer strictly punctual, but in practice is analyzed as a connection type pivot.
  • the movable contact and its shaft remain well in position at the bottom of the two rectilinear grooves, because this double contact exerts an action substantially in the direction of the axis of the groove, the stable positioning of the subassembly articulation also resulting from the opposite actions exerted on both ends of the spring by said tab on the one hand and an opposite surface in the housing on the other hand.
  • the movable contact consists of two symmetrical elements, each element comprising a first extended portion contiguous to the symmetrical portion of the other element to form the arm and a second portion formed of a ear offset outwardly creating with the symmetrical ear of the other element an interior space of predetermined width, said second portion being pierced with an orifice for the passage of the shaft and having the lugs provided to cooperate with the springs .
  • the electrical connection with the fixed support is carried out by a contact pad whose geometry makes it possible both to ensure the relative rotational movement and the passage of a certain current density.
  • the caliper design is a good solution that makes it possible to respect both constraints, and can be optimized by means of adjustments made to the different parts of the components.
  • the first portion may comprise a longitudinally stiffening stiffening rib, knowing that it undergoes flexural stresses, especially at the moment of pressing against the fixed contact.
  • the second portion can also take a circular geometry naturally conducive to rotation and offers a constant connection range despite the relative movement of the arm and the support.
  • the movable arm can move in a window formed in a wall of the housing, particularly at the moment of relative rotation ensuring the contact pressure.
  • a fraction of it can be opened, giving access to the components of the hinge subassembly placed inside the housing.
  • the opening of the contacts causes an electric arc whose displacement can affect this part, and potentially destroy or damage the electromechanical link.
  • the first portion of the arm of the movable contact may further comprise at least one stud for fixing a protective shield of said components.
  • the support of the movable contact is constituted of a part comprising a first section of planar shape provided with a through hole of the shaft, of width substantially equal to the predetermined width of the internal space of the moving contact. and of geometry forming a contact pad with the facing faces of the interior space, said first section being transformed outside the housing into a second section configured to form an interface with the detection means.
  • the portion of the first section of said support forming this contact area with the movable contact is of circular shape.
  • the interface with the detection means may consist of a conductive rod extending said first section, intended to pass into a toroid-type current sensor and whose free end at the output of the toroid is provided with a range of connection to an electric cable of the protected line.
  • This case corresponds to the electronic detection means which comprise a toroid operating as a current sensor sending to a processing electronic circuit a signal proportional to the current which passes in the line.
  • the electronic circuit can activate an actuator of the mechanical trigger lock.
  • said first section may be extended into a flat sheet having a thickness substantially equal to that of said first section and pierced with a passage opening of a connecting screw to the detection means.
  • This version is intended to operate with magnetothermic detection means, essentially a magnetic coil and for example a bimetallic strip, positioned in the housing of the device so as to trigger the mechanical lock.
  • magnetothermic detection means essentially a magnetic coil and for example a bimetallic strip
  • this support provided for cooperating with magnetothermic detection means is formed by two symmetrical parts relative to the longitudinal median plane of the arm of the movable contact at least in the first section, each part being extended by a portion of symmetrical appearance to that of the other party with free ends overlapping at the location of the piercing.
  • the circuit breaker 1 shown therein having in this case a molded insulating housing B, conventionally comprises a control lever 2 connected via a mechanical lock 3, which is not described in detail because it does not constitute the invention, a contact carrier (s) 4 supporting a movable contact 5 provided to cooperate with a fixed contact 6.
  • Means of connection to the line 7, 8 to be protected are arranged on either side of the fixed contact torque 6 / movable contact 5.
  • the mechanical lock 3 echoes the movements of the control lever 2.
  • this control handle 2 can be tilted at both ends of the rotary path it can travel in the housing, corresponding to two stable positions each reflecting a state of the contacts, either open and at a distance from one another, or closed and supported one on the other.
  • the mechanical lock 3 comprises in particular a toggle-type mechanism which makes it possible to transmit the printed displacement to the control lever 2 to the contact carrier (s) 4 and to the moving contact 5.
  • detection means 9 thermo for example in the form of a bimetallic and magnetic for example in the form of a coil and a magnetic circuit with movable blade

  • the rotation is twofold: the contact-holder unit (s) 4 / movable contact 5 is on the one hand mobile in rotation between the closed position, for example appearing in figure 2 and an open position as shown in figure 4 , and there is on the other hand a relative rotation of the contact carrier (s) 4 and the movable contact 5 to ensure the contact force in the closed position shown in FIG. figure 2 .

  • the latter further comprises, at the end of the arm 16 forming the first portion of the movable contact 5, a contact pad 17 intended to bear against a counterpart contact pad 17 'provided on the fixed contact 6.
  • the arm 16 of the movable contact 5 further comprises a stiffening rib 18, and a stud 19 which serves to fix a protective shield 20 appearing in figure 2 .
