Definitions

  • the present invention relates to a rapid control device for a high voltage connection device, in particular an earthing switch, equipped with a movable contact comprising an energy storage spring mechanical, a mechanism for arming this spring comprising a motor electric arranged to drive at least one rotary part arranged to occupy two stable positions corresponding respectively to the armed spring and to the disarmed spring, this arming mechanism being provided with a link coupled to a mechanism for controlling a movable contact, this link being associated with a brake damping device acting as a stop for said rod in the positions it occupies when said rotary part occupies said two stable positions.
  • a device of this type is known from the published French patent application under the number 2 766 961.
  • a single shock absorber consisting for example a rubber stop housed in a cylindrical sleeve and rigidly mounted in the device housing, cooperates with a link coupled to the control mechanism of a movable contact to stop this rod in its two stable positions and to absorb the shocks which result.
  • the object of the present invention is to overcome the drawbacks of the art by making a device for which the damping of the link coupled to the mobile contact control mechanism is carried out efficiently and economically satisfactory.
  • a device as described in the preamble characterized in that said brake damping device comprises at least one damper hydraulic mounted on a fixed support secured to the device housing by through a spring organ.
  • This spring organ has the function of contribute to the absorption of the shocks received during the arrival of the stop said link. Therefore, the fixing of the shock absorber itself and the stability of its mounting on its support inside the housing of the device are made safe and reliable.
  • said spring member comprises at least a stack of Belleville washers.
  • Such a known spring member is particularly robust while being economical.
  • said brake damping device has two hydraulic shock absorbers arranged in parallel and arranged to operate respectively as a stop for said link when the latter 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 meets the requirements required.
  • said mechanism for actuating a movable contact comprises a pivoting lever articulated on said link, this lever pivoting being integral with a control axis of said movable contact and carrying two support protrusions arranged to cooperate respectively with two piston rods of the two hydraulic shock absorbers.
  • Said protuberances are preferably arranged on an arm integral with the control axis of said movable contact.
  • said arm carrying said protrusions is advantageously mounted symmetrically with respect to the control axis of said mobile contact.
  • the device 10 quick control for high voltage connection device, and in particular for an earthing switch, equipped with a movable contact, such as shown, includes a spring 11 for accumulating mechanical energy, a arming mechanism 12 of this spring comprising an electric motor arranged to drive at least one rotary part 13 arranged to occupy two stable positions corresponding respectively to the armed spring and the disarmed spring, this arming mechanism 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 damping device 16 acting as a stop for said link in the positions it occupies when said piece rotary 13 occupies said two stable positions.
  • the damping device brake 16 comprises at least one hydraulic damper 17, respectively 18, mounted on a fixed support integral with the housing of the device via of a spring member 19, respectively 20.
  • the spring 11 housed in a cylindrical sleeve 11a, including the movable bottom 11b coupled to a chain 11c connected by a rod 11d to a part 12a which is articulated on said rotary part 13, is described in detail, as well as all associated components, in the publication mentioned above and illustrating prior art.
  • the actuating mechanism 15, associated with the link 14, comprises a lever 15a which is pivotally mounted on the control axis 15b of said movable contact (not shown).
  • This lever is articulated at a point 15c on the link 14.
  • It also includes an arm 15d, integral with this lever or rigidly fixed to the control axis 15b, this arm being mounted symmetrically with respect to the axis 15b and carrying at its ends two support protrusions 15e and 15f.
  • the support protrusions 15e and 15f are arranged to cooperate respectively with the piston rods of two hydraulic shock absorbers 17 and 18 of the brake damping device 16.
  • a hydraulic damper 17 or 18 of the brake damper device 16 is represented by FIG. 2. It comprises a threaded body 21 of cylindrical shape screwed into a cylindrical socket 22, surmounted by the spring member 20, consisting of a stack of Belleville washers.
  • the cylindrical socket 22 is engaged in a bore 23 of a support 24 in the form of a bracket, secured to the device housing by a pin 25 or any other suitable fixing means.
  • a nut 26 makes the threaded body 21 of the shock absorber integral with the cylindrical sleeve 22.
  • a double nut 27 blocks the stack of Belleville washers against the bush 22 and in abutment the support 24.
  • a piston rod 28, extending axially from the body of the damper is arranged to cooperate with the protrusion 15f.
  • the present invention is not limited to the embodiment described, but may undergo various variations or modifications obvious to a person job.
