Definitions

  • the present invention relates to a control mechanism of a multipole electrical switch of the output shaft type carrying or actuating contacts and capable of being selectively brought into three stable positions, an open position, a closed position of the switch and an earthing position, said main shaft being rotated by indexing means cooperating with firstly a first device for closing and opening the switch and secondly for a second device for controlling the grounding.
  • Tumbler mechanism is an energy storage system that uses a compression spring whose energy is suddenly released when said previously compressed spring exceeds a point of equilibrium during the maneuver.
  • the energy released by the spring is transmitted to the output shaft to cause its rotation, the actuation of the opening and closing device of the switch or the grounding device serving only to compress the spring that stores the energy required for the sudden rotation of the output shaft.
  • This type of mechanism has the disadvantage of including a large number of parts, which, in addition to reliability problems, strike the assembly time and, therefore, the manufacturing costs of these mechanisms.
  • Controlling mechanisms are also known for a multipolar switch comprising a single control device cooperating with a single accumulator spring in order to occupy three distinct stable positions, a first closed position, a second open position and a closed position. third grounding position; this is the case, for example, French patent FR 2,500,222 .
  • the mechanism described in this document which according to the preamble of claim 1, comprises a unique accumulator spring able to actuate the switch in one of three positions.
  • the opening and closing control axis coincides with the shaft of the operating cam of the drive lever of the moving equipment.
  • the lever for actuating the toggle joint is arranged between the shaft of the operating cam and the control shaft of the grounding crank.
  • This mechanism does not meet the standards in force which impose two separate control devices, a closing and opening control device and an earthing control device.
  • the FR 2,651,603 discloses a control mechanism of a similar multipolar switch having two control devices called control cranks, a closing and opening control crank on the one hand and a ground control crank on the other hand, cooperating with a single accumulator spring.
  • the mechanism comprises a toggle energy accumulator device composed of a crank arm articulated by an axis to a telescopic guide for supporting a compression spring, a first control crank mounted on an arming shaft, and coupled by a transmission rod to a second control crank, which is keyed on an actuating shaft of the switch, and control means of the arming crank to cause the crossing of neutral position of the toggle during the passage of the mechanism from the closed position to the open position, and vice versa.
  • the arming crank is mounted idle on a cocking shaft cooperating with drive cleats of the first control crank.
  • the telescopic spring guide is supported on a crank pin located on the second control crank, for generating during the arming operation of the spring a temporary holding torque of the first and second cranks in their initial state until the breaking of the toggle joint.
  • the control means of the arming crank comprises a transmission mechanism controlled either automatically by a geared motor unit or manually by a shaft coupled to an emergency control by a rod. The presence of the temporary holding torque during the cocking of the spring results from the relative positioning of the toggle relative to the second control crank, and avoids the use of additional locks or snaps.
  • One of the aims of the invention is therefore to overcome all these disadvantages by providing a compact control mechanism of simple and inexpensive design.
  • a control mechanism of a multipole electrical switch of the output shaft type carrying or actuating contacts and capable of being selectively brought into three stable positions, a position of an opening, a switch closing position and a grounding position
  • said mechanism being of the Tumbler type having a single energy storage spring, two control cranks, a first closing control crank and a opening on the one hand and a second ground control crank on the other hand, and means adapted to rotate the output shaft from its open position to its closed position and vice versa when the first control crank is actuated and the rotation of the output shaft to its grounded position when the second control crank is operated, the first crank of control being then in the open position;
  • said mechanism is remarkable in that a first end of the single energy storage spring is articulated to a vertical flange about an axis extending parallel to the output shaft and the other end carries a cylindrical roller mounted free to rotate about an axis parallel to the output shaft and cooperating on the one hand with indexing means capable of driving into rotation
  • the indexing means consist, on the one hand, of a fixed cam path integral with the flange of the mechanism on which the roller rolls and, on the other hand, of a flat piece known as indexing, mounted free to rotate about an axis extending parallel to the output shaft, and provided with a day whose edges form a second so-called mobile cam path.
  • Said fixed cam path consists in the upper free edge of a vertical plate secured to the flange by spacers, said free edge having a hollow curve in its middle part, the concavity being oriented towards the output shaft, and, on either side of this central hollow, respectively a secondary recess, having a depth less than the depth of the central recess, and terminated by a vertical wall forming a stop, the free edge being convex between the central recess and the secondary recesses.
  • the control mechanism of a multipole switch comprises a pair of vertical flanges 1 forming a support and separated by spacers 2, a single flange 1, the rear flange, being shown in the figures.
  • the rear flange 1 comprises in its plane of symmetry corresponding to the sagittal plane of said flange 1 an output shaft 3 actuating a multipole electrical switch, not shown, capable of being selectively brought into three stable positions, an open position, a position of the switch and a grounding position, such as the multipole switch described in the French patent FR 2,606,209 for example.
