Definitions

  • the present invention relates to a mechanism for driving the signaling contacts of an electrical appliance, in particular a high voltage disconnector or an earthing switch.
  • a drive mechanism for a rotary switch for signaling the position of a high-voltage electrical appliance in particular a disconnector or an earthing switch, connecting this switch by its rotation of a rotary shaft of a mechanism for actuating the contacts of the device so that the contacts of this contactor are open or closed when the contacts of the device are open or closed, this shaft being moved at a speed ⁇ ht during an opening or closing operation of the device contacts.
  • the mechanisms currently used to drive the high voltage disconnector or earthing switch signaling contactors are generally of the snap action type. They include a cam integral with the actuation shaft of the actuation mechanism of the contacts of the device actuating a spring or lever switch. In this way, a significant switch operating speed is obtained at the end of the stroke.
  • Such rotary switches generally consist of two fixed contacts each having a branch in an arc of a circle, these two fixed contacts being opposite.
  • the movable contact is itself made up of two rotary bars, between the ends of which are fixed the fixed contacts in the closed position ensuring the electrical connection between these fixed contacts.
  • the present invention solves these problems by proposing a drive mechanism which, while being positive-acting, is suitable for high voltage disconnectors as well as earthing switches.
  • the drive mechanism is a positive action connection between said shaft and said rotation shaft and comprises means for driving the rotation shaft of the switch at the start and at the end of maneuver at a speed ⁇ cs greater than ⁇ ht.
  • said means consist of two studs integral with said shaft, located in a plane perpendicular to this shaft and equidistant from this tree and in a disc integral in its center with said rotation shaft, located in a plane perpendicular to this shaft and provided with two radial direction grooves intended to each receive one of said pins, the two shafts being parallel.
  • the slots are symmetrical with respect to an axis passing through the center of the disc.
  • each slot comprises at least one first sector in the form of an arc of a circle of radius equal to the distance between each tenon and the shaft and the shaft is arranged along the axis passing through the center of the corresponding circle.
  • said slots can each be extended by a second terminal stabilization sector.
  • Figure 1 is an exploded perspective view of the drive mechanism according to the invention.
  • Figure 2 is a top view of the mechanism.
  • FIGS. 3A to 3D are views diagramming the operation of the drive mechanism according to the invention during an opening operation of the electrical appliance.
  • a rotary switch 1 is shown in FIG. 1. It comprises two fixed contacts 2A, 2B opposite one another, each having a branch in an arc of a circle 3A, 3B.
  • the movable contact is itself made up of two bars 4A, 4B applied one on the other with a space between them and rotary secured to a shaft 5 said shaft of rotation of the switch.
  • the ends of the arms 4A, 4B of the movable contact come into contact with the fixed contacts 2A, 2B by fitting them between these ends, ensuring the electrical connection between these fixed contacts 2A, 2B.
  • the movable branches 4A, 4B are moved away from the fixed contacts 2A, 2B and the switch is open.
  • Such a rotary switch 1 is known per se.
  • It serves as a signaling switch for a high-voltage electrical appliance, in particular a disconnector or an earthing switch, by connecting it by its rotation shaft 5 to the rotary shaft 6 of a mechanism actuating the device contacts so that the contacts of this contactor 1 are open or closed when the device contacts are open or closed.
  • a first disc 7 located in a plane perpendicular to this shaft and carrying two pins 8A, 8B equidistant from the center 7A of the first disc 7 and angularly spaced at an angle to the center ⁇ .
  • a second disc 9 located in a plane perpendicular to this shaft and provided with two grooves or slots 9A, 9B in radial direction and the shape of which will be specified later with reference to FIG. 2.
  • the two shafts 5, 6 are parallel and the two discs 7, 9 are arranged relative to each other so that, during the rotation of the actuation shaft 6 at a speed ⁇ ht during d '' a closing or opening operation of the electrical device, the pins 8A, 8B are fitted into the slots 9A, 9B and cause the second disc 9 to rotate in rotation at a speed ⁇ cs greater than ⁇ ht at the start and at the end of the maneuver.
  • FIG. 2 A preferred embodiment of this preferred arrangement is visible in FIG. 2.
  • the slots 9A, 9B are symmetrical with respect to an axis passing through the center of the second disc 9 where the rotation shaft 5 of the switch 1 is secured. In the radial direction, they open at the periphery of the disc 9 at angularly spaced points. of an angle at the center ⁇ .
  • the shaft d actuation 6 is in turn disposed along the axis passing through the center of the corresponding circle, when the part 9 is in the middle position as shown in Figures 3B and 3C.
  • a second terminal stabilization sector 9A2, 9B2 which is preferably substantially straight and parallel to the axis of symmetry of the two slots 9A, 9B.
  • the two discs 7, 9 are arranged relative to each other so that, during the rotation of the first disc 7, the stud 8A is embedded in the slot 9A or the stud 8B is embedded in the slot 9B , ensuring the positive action connection of the two discs 7, 9 and therefore of the shaft actuation 6 of the actuation mechanism of the apparatus and of the rotation shaft 5 of the switch 1. Furthermore, the dimension of the second disc 9 and its slots 9A, 9B as well as the distance between each tenon 7A, 7B and the center 7A of the first disc 7 and the dimension of the angle ⁇ are chosen to obtain a complete stroke of the fixed contact of the switch 1 taking into account the complete rotary stroke of the actuation shaft 6 of the mechanism actuation of the device contacts. They are also chosen so that at any time one of the two studs is in contact with one of the sectors 9A and 9B.
  • first signaling switch 1A and a second signaling switch 1B whose common rotation shaft symbolized by line 5 is connected to the shaft symbolized by line 6 of the actuation mechanism of the contacts of a disconnector symbolized in 10.
  • the first signaling switch 1A is intended to be open when the disconnector 10 is closed and to be closed when the disconnector 10 is open.
  • the second switch 1B is intended to be closed when the disconnector 10 is closed and to be open when the disconnector 10 is open. More than two switches can be associated with the disconnector 10 according to the same principle.
  • the actuation shaft 6 and therefore the first disc 7 rotate at a speed assumed to be constant ⁇ ht .
  • the pin 8B drives the second disc 9 and therefore the rotation shaft 5 of the switches 1A, 1B at a speed ⁇ cs greater than the speed ⁇ ht , the terminal sector of the slot 9B being close to tree 5.
  • the Signaling switches therefore quickly come to the closed position for the first 1A and to the open position for the second 1B.
  • the pin 8A in the terminal part of the slot 9A then drives the second disc 9 and therefore the shaft 5 at a speed ⁇ cs greater than the speed ⁇ ht .
  • the switches quickly end their closing movement for the first 1A and opening for the second 1B.
  • the rotation speed ⁇ cs of the switch is to it fast ensuring a frank and reliable opening and closing, while guaranteeing a positive action connection during the whole maneuver.
