Definitions

  • the present invention relates to an opening and / or closing control device in particular for a breaking device such as a circuit breaker in accordance with the preamble of claim 1 (see FR-A-1 324 466 for example).
  • a device comprising a linearly sliding armature mounted in a support, two permanent magnets arranged on either side of the sliding axis of the armature and one or more winding (s) mounted around the armature and suitable for generate a magnetic field parallel to the above sliding axis. It follows from this linear displacement of the reinforcement, which a relatively large air gap has to be overcome start of movement of the armature to the active position. As a result, a large amount of energy (ampere-turns) at the start is necessary to train the frame.
  • the present invention solves these problems and proposes a device for controlling simple design, in which the energy required at the start is reduced and presenting a high efficiency, as well as a circuit breaker equipped with such a device.
  • the present invention relates to a device of the kind previously mentioned, this device being characterized in that the aforementioned armature is mounted movable in rotation between two stops formed in the support, said stops delimiting respectively the two aforementioned positions.
  • the frame comprises a shaped part elongated having two opposite ends of arcuate shape, said part being mounted in rotation about an axis extending perpendicular to the longitudinal direction of the armature.
  • the device comprises two windings capable of generate respectively when excited, two magnetic fields of opposite direction, of so as to rotate the armature respectively in one direction to achieve the opening operation of the contacts, and in an opposite direction to carry out an operation of contact closure.
  • the two windings are each located between the two magnets, respectively on one side and the other of the axis so as to be offset mutually and angularly at an angle of about 180 °.
  • the invention also relates to a circuit breaker comprising the characteristics previously mentioned taken alone or in combination.
  • an operating device intended to ensure the opening of the contacts a breaking device such as a medium voltage circuit breaker placed in a circuit electrical, upon the appearance of an electrical fault such as an overvoltage in said circuit.
  • the device comprises a frame 9 of general elongated shape having two ends of arcuate shape 9a, 9b, secured to a actuating rod 10 extending perpendicular to the longitudinal direction of the frame 9.
  • This frame 9 is mounted to rotate freely in a support block 13 between two positions delimited by stops 11,12 formed in said support 13.
  • the block support 13 therefore comprises for this purpose two guide surfaces in rotation 14,15 of the armature, of circular shape, arranged opposite to the X axis of rotation of the armature 9, and each extending between the two stops 11,12, said surfaces being able to cooperate with the two aforementioned ends 9a, 9b of the frame 9.
  • stops 11,12 are angularly offset from each other, relative to the axis X of rotation of the frame, at an angle of about 50 °.
  • the two stops 11,12 are shaped complementary to the parts 9c, 9d of the armature 9 intended to be brought into contact with said stops.
  • Each of these stops 11,12 consists of two parts 11a, 11b, 12a, 12b of the same orientation, arranged symmetrically with respect to the other, relative to the axis X of rotation of the armature 9.
  • this support block 13 are arranged two permanent magnets 16,17 arranged opposite one with respect to the other and relative to said axis X, each along one of the two guide surfaces 14.15, substantially in the middle of the circumference of these surfaces 14.15, said magnets 16,17 then being mutually and angularly offset with respect to the X axis of a angle of about 180 °.
  • the direction of magnetization of these magnets 16,17 is as represented by the arrows in Figures 1 and 2.
  • the device further comprises two coils 18,19 each consisting of a single winding, said coils 18,19 being located on either side on the other side of the frame 9 between the guide surfaces 14,15 while being offset by an angle about 180 ° relative to each other around the X axis, each of the coils being located between the two magnets 16,17.
  • the magnets and coils are offset successively and alternately around the axis at an angle of approximately 90 °.
  • the device In normal circuit operation, the device is in the closed circuit breaker position shown in Figure 1. In this position, the armature 9 bears against the first stop 11a, 11b and retained in this position by the two permanent magnets 16,17. then from the appearance of an opening order, the energy supplied to the corresponding coil 18 generates the excitation of the latter until the force of attraction of the magnets permanent 16.17 is less than the force associated with the magnetic field generated by the coil. Then, the frame 9 is rotated clockwise. At the start of this movement, the starting air gap f is close to zero, the only air gap influencing e being constant and of low value. As a result, the energy required initially for the frame 9 comes off the stop 11 is weak.
  • opening order can be sent for example by an action intended to separate the contacts, or directly following the appearance of an electrical fault in the circuit.
  • the value of the closing and opening torques depends on the arrangement of the magnets, that is to say the direction of their magnetization.
  • the direction of magnetization can be chosen so that the closing torque is high and the opening torque low (the field of the opening coil being in the sense of magnets).
  • this device can advantageously be used to ensure inter alia the vacuum circuit breaker control.
  • a stable actuator is obtained in the two limit positions without supplying the coils, the electrical energy being supplied to the coils only during the movement of the armature.
  • the realization of the bistable in rotation leads to all the forces being balanced, hence a greater yield of the device without too great forces being generated on the bearings.
  • the external parts E of the actuator will advantageously be made of so as to limit the induced currents.
