Definitions

  • the present invention relates to a rapid control device for a high-voltage connection apparatus, in particular an earthing switch, equipped with a movable contact comprising a mechanical energy storage spring, an arming mechanism of this spring comprising an electric motor arranged to drive at least one rotating part arranged to occupy two stable positions respectively corresponding to the armed spring and the disarmed spring, this cocking mechanism being provided with a rod coupled to a control mechanism of a movable contact, this connecting rod being associated with a brake damping device acting as a stop for said link in the positions it occupies when said rotating part occupies said two stable positions.
  • a device of this type is known from the French patent application published under the number 2,766,961.
  • a single damper consisting for example of a rubber abutment housed in a cylindrical sleeve and rigidly mounted in the housing of the device , cooperates with a rod coupled to the control mechanism of a movable contact to stop this rod in its two stable positions and to damp the shocks resulting therefrom.
  • the object of the present invention is to overcome the disadvantages of the prior art by providing a device for which the damping of the connecting rod coupled to the control mechanism of the movable contact is effected efficiently and economically satisfactory.
  • said damping brake device comprises at least one hydraulic damper mounted on a fixed support integral with the device housing by means of a spring member.
  • This spring member has the function of contributing to the damping of the shocks received at the abutment of said rod.
  • said spring member comprises at least one stack of Belleville washers.
  • Such a known spring member is particularly robust while being economical.
  • said brake damper device comprises two hydraulic dampers arranged in parallel and arranged to operate respectively as an abutment for said link when it occupies its positions corresponding to the two stable positions of said rotating part.
  • This type of standard commercial shock absorbers is particularly economical and resistant, which corresponds to the required requirements.
  • said mechanism for actuating a movable contact comprises a pivoting lever articulated on said link, this pivoting lever being integral with a control pin of said movable contact and carrying two bearing protuberances arranged to cooperate. respectively with two piston rods of the two hydraulic dampers.
  • Said protuberances are preferably arranged on an arm secured to the control shaft of said movable contact.
  • said arm carrying said protuberances is advantageously mounted symmetrically with respect to the control axis of said movable contact.
  • the rapid control device 10 for a high-voltage connection device and in particular for an earthing switch, equipped with a movable contact, as shown, comprises a spring 11 mechanical energy accumulation, an arming mechanism 12 of this spring comprising an electric motor arranged to drive at least one rotating part 13 arranged to occupy two stable positions respectively corresponding to the armed spring and the disarmed spring, this mechanism of armament 12 being provided with a rod 14 coupled to an actuating mechanism 15 of a movable contact.
  • the rod 14 is associated with a brake damper device 16 acting as a stop for said rod in the positions it occupies when said rotating part 13 occupies said two stable positions.
  • the brake damper device 16 comprises at least one hydraulic damper 17, respectively 18, mounted on a fixed support integral with the device housing via a spring member 19, respectively 20.
  • the spring 11 housed in a cylindrical sleeve 11a, the movable bottom 11b coupled to a chain 11c connected by a rod 11d to a part 12a which is articulated on said rotating part 13, is described in detail, as well as all the associated components, in the publication mentioned above and illustrating the prior art.
  • the actuating mechanism 15, associated with the rod 14, comprises a lever 15a which is pivotally mounted on the control shaft 15b of said movable contact (not shown). This lever is articulated at a point 15c on the rod 14. It further comprises an arm 15d, integral with this lever or rigidly fixed on the control shaft 15b, this arm being mounted symmetrically with respect to the axis 15b and bearing at its ends two bearing protuberances 15e and 15f.
  • the bearing protuberances 15e and 15f are arranged to cooperate respectively with the piston rods of two hydraulic dampers 17 and 18 of the brake damping device16.
  • a hydraulic damper 17 or 18 of the brake damper device 16 is represented in FIG. 2. It comprises a threaded body 21 of cylindrical shape screwed into a cylindrical sleeve 22, surmounted by the spring member 20, consisting of a stack of washers of Beautiful city.
  • the cylindrical sleeve 22 is engaged in a bore 23 of a bracket 24 in the form of a bracket, secured to the housing of the device by a pin 25 or other suitable fastening means.
  • a nut 26 makes the threaded body 21 of the damper integral with the cylindrical sleeve 22.
  • a double nut 27 blocks the stack of Belleville washers against the bushing 22 and bears against the support 24.
  • a piston rod 28, outgoing axially of the body of the damper, is arranged to cooperate with the protuberance 15f.
