Definitions

  • the present invention relates to a mechanism for signaling device contacts electric, in particular a high voltage disconnector or an earthing switch.
  • It relates more precisely to a drive mechanism of 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 shaft 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 train high disconnector signaling contactors voltage or earthing switch are generally of the snap action type. It include a cam secured to the actuation shaft of the mechanism for actuating the contacts of the device actuating a spring or lever switch. This way is obtained a high operating speed of the switch at the end of the race.
  • Such rotary switches are in general consisting of two fixed contacts each having a branch in an arc, these two fixed contacts being in vis-a-vis.
  • the mobile contact consists of two rotary bars, between the ends of which fixed contacts are fixed in position closure ensuring the electrical connection between these contacts fixed.
  • the present invention solves these problems, by offering a drive mechanism which, while being positive action, suitable for high voltage disconnectors as well as to earthing switches.
  • the drive mechanism is a positive action link between said shaft and said rotation shaft and comprises means for driving the rotation shaft of the switch at the start and 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 tree and equidistant from this tree and in a disc united in its center of said rotation shaft, located in a plane perpendicular to this shaft and provided with two radial direction slots intended to each receive one of said studs, both trees being parallel.
  • the slots are symmetrical by relative to an axis passing through the center of the disc.
  • each slot has at least a first shaped sector of arc of 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 sector stabilization.
  • 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 schematizing the operation of the drive mechanism in accordance with the invention during an opening operation of the device electric.
  • a rotary switch 1 is shown in the figure 1. It has two fixed contacts 2A, 2B facing each other each having a branch in an arc 3A, 3B.
  • the mobile contact consists of two bars 4A, 4B applied one on top of the other with a space between them and rotary secured to a shaft 5 said rotation shaft of the switch.
  • the ends of branches 4A, 4B of the movable contact come into contact with fixed contacts 2A, 2B by embedding these between these ends, ensuring the electrical connection between these fixed contacts 2A, 2B.
  • the mobile branches 4A, 4B are distant from 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 device high voltage electrical, in particular a disconnector or an earthing switch, connecting it by its rotation shaft 5 to rotary shaft 6 of a mechanism actuation of 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 tree and carrying two tenons 8A, 8B equidistant from the center 7A of the first disc 7 and angularly spaced at an angle at center ⁇ .
  • a second disc 9 located in a plane perpendicular to this tree and provided with two grooves or slots 9A, 9B with radial direction and the shape of which will be specified below with reference to Figure 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.
  • the slots 9A, 9B are symmetrical with respect to a axis passing through the center of the second disc 9 where is secured to the rotation shaft 5 of the switch 1. From radial direction, they open at the periphery of the disc 9 at points angularly spaced at an angle at ⁇ center.
  • first sector 9A1, 9B1 in shape of arc of circle of radius equal to the distance between each tenon 8A, 8B and the center 7A of the first disc 7.
  • the shaft actuator 6 is arranged along the axis passing through the center of the corresponding circle, when the part 9 is in the middle position as shown in the Figures 3B and 3C.
  • the two discs 7, 9 are arranged one with respect to the other so that when rotating the first disc 7, the tenon 8A is embedded in the slot 9A or the pin 8B is embedded in the slot 9B, ensuring the connection positive action of the two discs 7, 9 and therefore of the shaft 6 of the device's actuation mechanism and of the rotation shaft 5 of the switch 1. Furthermore, the size of the second disc 9 and its slots 9A, 9B as well as the distance between each post 7A, 7B and the center 7A of the first disc 7 and the dimension of the angle ⁇ are chosen to obtain a full stroke of the fixed contact of the switch 1 taking into account the complete rotary stroke of the actuation shaft 6 of the actuation mechanism of the device contacts. They are also chosen from 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 switching switch 1B signaling including the common rotation tree symbolized by line 5 is connected to the tree 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 opened 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 shaft 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.
