Definitions

  • the invention relates to a breaking device for a low-voltage multipole circuit breaker and with an insulating housing, comprising a rotary switching bar guided in rotation around a first transverse fixed axis by means of bearings provided in the housing, said first axis being perpendicular to the longitudinal direction of each pole, which comprises: - a pair of fixed contacts in connection with the connection pads; - A double-break rotary contact extending in a housing of the bar in the longitudinal direction of the pole, and having opposite contact parts cooperating with the fixed contacts in the closed position; - A pair of springs arranged inside the bar housing to cooperate with the rotary contact while ensuring a predetermined contact pressure of the contact parts on the fixed contacts;
  • the central part of the rotary contact comprises an oblong hole threaded on a fixed support rod to form a guide system having a degree of freedom in translation.
  • the fixed support rod has a cylindrical shape and is mounted coaxially in the bar, so that the rotary contact can move slightly in the direction perpendicular to the longitudinal axis of the pole to ensure a balanced contact pressure at the two cut-off intervals.
  • the diameter of the rod corresponds substantially to the width of the oblong hole, and any displacement of the rotary contact in the longitudinal direction is made impossible.
  • the longitudinal positioning of the rotary contact is precisely determined by the support rod, which imposes strict manufacturing tolerances.
  • the contact pressure springs do not provide effective self-centering of the movable contact in the longitudinal direction of extension of the connection pads.
  • the positioning of the movable contact relative to the fixed contacts may change during the life of the switch. This results in a longitudinal offset of the contacts which is harmful to breaking the arc.
  • the object of the invention is to simplify the mounting of a double-break rotary contact on the switching rod of a circuit breaker with molded insulating housing.
  • the breaking device is characterized in that the rotary contact is resiliently positioned by the springs along the longitudinal direction of the pole, and is capable of pivoting inside the housing around a second imaginary axis, mounted floating with respect to the first fixed axis of the bar, the maintenance of the rotary contact inside the bar housing operating with two degrees of freedom in translation, capable of simultaneously generating a torque of uniform distribution of the contact pressure on the two pairs of contacts, and an equilibrium position of the rotary contact obtained by the self-centering effect of the springs in the longitudinal direction.
  • the mounting of the rotary contact is simplified, and the presence of the only two springs ensures self-centering of the rotary contact on the second axis.
  • the latter can be confused with the first transverse fixed axis of the bar, or on the contrary move in a plane perpendicular to the first axis.
  • the springs cooperating with the rotary contact can be springs of the torsion, traction or compression type.
  • a breaking pole 10 of a low voltage circuit breaker is housed in a compartment of the housing 12 of molded insulating material.
  • the pole 10 comprises a rotary contact 14 with double break capable of pivoting about an axis 16 of rotation between a closed position ( Figure 1), and an open position (not shown).
  • the axis 16 of rotation is located in the central zone of the pole 10, and the rotary contact 14 is constituted by a pair of lever arms 18, 20 extending between the axis 16 of rotation and two contact parts 22, 24 opposite cooperating respectively with fixed contacts 26,28.
  • connection pads 30, 32 crossing two opposite faces of the housing 12.
  • the areas 30, 32 are aligned in the longitudinal direction 34 of the pole, and their internal ends carry the fixed contacts 26, 28.
  • An arc extinguishing chamber 36, 38 comprising a stack of metal sheets, is associated with each pair of contacts 26, 22; 28,24 located on the same side of the axis of rotation 16.
  • the nominal current flows through the main circuit of the pole by entering through one of the ranges, for example 30, and then passing through the fixed contact 26, the rotary contact 14, the fixed contact 28 to exit the pole by the other area 32.
  • the rotation of the movable contact 14 clockwise causes the two pairs of contacts 26,22 to separate simultaneously; 28,24, and the formation of two arcs connected in series.
  • the rotary contact 14 is driven in rotation by means of a switch bar 40 of insulating material extending in the transverse direction of the axis 16 of rotation of the contact 14.
  • the bar 40 is guided in rotation about an axis transverse fixed by means of bearings arranged in the housing 12.
  • the bar 40 occupies the central compartment 39 of the housing 12, separated from the extinguishing chambers 36, 38 by walls 37 of subdivision. Ports 35 are provided in the walls 37 for the passage of the movable contact 14.
  • a control mechanism (not shown) is mechanically coupled to the bar 40 to transmit the opening and closing movements to the different poles.
  • the rotary contact 14 of the pole 10 is positioned in a housing 41 of the bar 40 extending perpendicular to the transverse axis 16 and parallel to the longitudinal direction 34.
  • the functions of holding and guiding the rotary contact 14 inside the housing 41 are provided by a pair of torsion springs 42, 44 arranged coaxially along the axis. of rotation 16 on either side of the contact 14.
  • the first torsion spring 42 has a curved end 46 hooked in a notch 47 of the lever arm 18, and the opposite end 48 is stressed by the elasticity of the spring 42 in abutment against an internal projection 50 of the bar 40.
  • the notch 47 for hooking the spring 42 is located opposite the contact piece 22.
  • the second spring 44 is anchored in a similar manner in a notch 52 of the lever arm 20, and on an internal projection 54 of the bar 40.
  • the two projections 50, 54 of the bar 40 are diametrically opposite with respect to the axis of rotation 16.
  • the presence of the two torsion springs 42,44 urges the rotary contact in a counterclockwise direction to ensure a uniform distribution of the contact pressure of the contact parts 22,24 on the corresponding fixed contacts 26,28, and at the same time allows a elastic positioning of the movable contact 14 along the longitudinal direction 34 of the pole.
  • the second imaginary axis of rotation 16 of the movable contact 14 is mounted floating relative to the first fixed axis of the bar 40.
  • the movable contact 14 with double break tends towards a position of equilibrium in the longitudinal direction as a function of the manufacturing tolerances of the housing 12 and of the bar 40.
  • the positioning of the rotary contact 14 in the housing 41 of the bar 40 is effected by means of two tension springs 60,62 arranged in the median plane having as trace the longitudinal direction 34 of the pole.
  • the first tension spring 60 is interposed between a lug 64 fixed on a boss of the lever arm 18, and a lug 66 for anchoring secured to the bar 40.
  • the second tension spring 62 is mounted in a similar manner between a lug 68 of the lever arm 20 and a tab 70 of the bar 40.
  • the two lugs 64 and 68 of the rotary contact 14 with double break are diametrically opposite with respect to the axis of rotation 16. It is the same for the two legs 66 and 70 of the bar 40.
  • the two tension springs 60, 62 extend parallel to one another in an oblique direction relative to the horizontal direction 34 (FIG. 3). Such an arrangement of the springs 60, 62 makes it possible to generate both a torque of contact pressure, and an equilibrium position of the rotary contact 14 in the longitudinal direction 34.
  • the rotary contact 14 is associated with two compression springs 72,74 making it possible to obtain the contact pressure on the fixed contacts 26,28, and the longitudinal equilibrium position.
  • the rotary contact 14 can be separated from the fixed contacts 26, 28 by the effect of electrodynamic repulsion, while the bar 40 remains stationary until the control mechanism is triggered.
  • This repulsion effect is obtained by an appropriate shape, in particular in a loop, of the pads 30, 32 for supporting the two fixed contacts 26, 28.
