Definitions
- the invention relates to a drive mechanism of a movable contact member of a switchgear.
- Patent application FR-A-2 681 723 describes a mechanism with two parallelograms allowing the control of a vacuum bulb, driven by a spring.
- the mechanism described does not allows only very small angular displacements of the two parallelograms, which only slightly deform between the open position and the closed position of the mechanism. Therefore, the effort transmission ratio of the mechanism is almost constant.
- the force applied by the mechanism at the stem of the bulb is in an almost constant relationship with the force applied by the spring.
- the force applied by the spring to the mechanism decreases during the expansion in proportion to the elongation of the spring, the force applied by the mechanism at the stem of the bulb therefore also decreases during movement closing.
- An object of the present invention is to provide a drive mechanism for a switchgear such as a vacuum interrupter, which does not have the drawbacks identified above, and in particular ensures a significant effort transmission report at the end of the closing stroke, so that the residual force of the closing spring partially unloaded at the end of the closing stroke is sufficient to ensure the contact pressure.
- the decrease in the force applied by the spring and due to the partial relaxation of at closing is this at least partially offset by the increase of the transmission report.
- the increase in the transmission ratio is continuous between the separation position and the contact position.
- transmission relationships discussed in this talk are static transmission ratios, such as can be measured when the parts in play are immobile. More specifically, the transmission ratios considered can be measured in each position of the mechanism, immobilizing the contact member or the drive member in the selected position. This is what the expression "in the absence of movement "used previously.
- This increase contributes at least partially to the increase in the overall transmission ratio ⁇ .
- the first lever comprises a member for connection to the closing spring
- the second lever comprises a connecting member to a closing latch capable of preventing movement of the parallelogram from its position opening to its closed position.
- the first lever comprises a member for connection to the closing spring
- the second lever comprises a member for connecting to means for applying an opening driving force.
- the transmission means comprise means for guiding the drive member with respect to the chassis, leaving the member drive at least one degree of freedom of translation relative to the chassis.
- the transmission means comprise means for guiding the drive member with respect to the transmission rod leaving the drive member at least a degree of freedom of translation relative to the connecting rod.
- the angle of rotation of the first and second levers between the open position and the closed position is important.
- the mechanism of the invention is thus compatible with a closed / open control and allows to easily dimension the closing spring independently of each other and the opening spring.
- a three-pole vacuum circuit breaker 10 includes a frame constituted by parallel flanges 14 fixed to each other and held in position by spacers 16, 18.
- the flanges 14 separate three pole compartments 20.
- Each polar compartment receives a vacuum interrupter 22 comprising a fixed contact 24 integral with an insulating envelope 26, and a movable contact 28.
- a material support axis 30 of the fixed contact 24 is pivotally mounted relative to the two flanges 14 delimiting the compartment.
- This support 30 comprises a bore 32 for guiding in translation for a rod 34 at the end of the fixed contact.
- a contact pressure spring 36 with a flange is disposed between the support 30 and the body of the envelope.
- the movable contact 28 comprises a rod whose head 40 comes out of the envelope and forms a stirrup.
- the movable contact defines a longitudinal geometric axis which, when the contact mobile is centered relative to the envelope and located in the extension of the fixed contact, coincides with the radial geometric axis of translation of the envelope defined by the bore 32.
- the stirrup 40 has two cheeks 44 each provided with a bore.
- An axis 46 is arranged transversely in the stirrup and passes through the bores of the cheeks 44.
- the axis 46 supports a central roller 48 located between the cheeks 44 and two lateral rollers 50 at its ends outside cheeks 44.
- the two flanges 14 framing each pole have two oblong holes 52 similar located one opposite the other.
- Each oblong hole 52 defines an axis longitudinal which is arranged radially with respect to the geometric pivot axis of the support 30 of the casing 26.
- the longitudinal axis of the oblong 52 intersects the geometric pivot axis of the support 30 and is perpendicular thereto.
- the pebbles lateral 50 of axis 46 each cooperate with the oblong hole 52 made in the flange 14 corresponding to the chassis 12, so that the stirrup 40 is free to move in translation relative to the flanges 14 parallel to the longitudinal axes of the oblongs, and pivot around the rollers 50.
- the mechanism for driving the mobile contact comprises a lower stage, a stage upper and a control stage.
- the lower stage comprises a switching bar 53 common to the three poles, consisting of a hexagonal shaft mounted in bearings supported by the flanges 14.

Axes 66, 68, 62 and the shaft 53 are all parallel to each other and perpendicular to the flanges 14. The connecting rod 64 is thus able to move parallel to itself when the bar of switching 53 pivots.
- the central roller 48 of the axis 46 cooperates with the oblong light 70 of the connecting rod 64.
- the axis 46 cooperates both with the oblong lumen 70 and with the oblong holes 52, so that its position is always determined by the position of the intersection between the oblong holes 52 and the oblong lumen 70.

- the coupling between the arming shaft 82 and the drive means comprises a free wheel (not shown) which couples the drive means to the shaft when the means drive transmit clockwise motor torque to the shaft, and otherwise disengage the drive means.
- the armament tree 82 is also provided with a second freewheel (not shown) relative to one of the flanges 14, which prohibits the rotation of the shaft 82 anti-clockwise and authorizes rotating the shaft clockwise.
- the camshaft 80 is provided with three identical multifunctional cams 88, one per pole 20.
- Each multifunction cam 88 has a first concave active surface 90 capable of cooperate with the opening roller 76, as well as a second active staircase surface consisting of an area in an arc 92 centered on the geometric axis of the tree and a locking stop 94.
- Each cam 88 also includes a roller 96 intended to cooperate with the cam 83 of the cocking crank 84.
- the multi-function cam of the pole central is recalled clockwise in the figures by an opening spring 98 fixed to a pin 100 held in one of the lateral flanges and to a pin 102 fixed to the cam and off-center with respect to its axis of rotation 80.
- the multifunction cams of both side poles are each provided with a closing spring 106, one end of which is hooked to the cam 88 by means of a pin 108 coaxial with the ankles 102 lateral multifunction cams, the other end of which is attached to the ankle 72 of the crank lever 58.
- a closing spring 106 one end of which is hooked to the cam 88 by means of a pin 108 coaxial with the ankles 102 lateral multifunction cams, the other end of which is attached to the ankle 72 of the crank lever 58.
- the opening 98 and closing 106 springs are tension springs, i.e. springs whose potential energy increases when are stretched.
- the movement of the cams 88 is limited clockwise by a stop of limit switch 110.
- the control stage is located between the flanges of the central pole. It brings together a open command and a close command.
- the opening command comprises, between the flanges of the central pole, a latch aperture 116 in half-moon shaped on a rotary axis 118 supported by bearings mounted on the flanges of the central pole.
- This lock is intended to cooperate with the second active surface of the multi-function cam 88 of the central pole. It is recalled in the sense counterclockwise in the figures by a return spring 120. From known manner and not shown, the lock 116 is connected to a release member allowing it to be triggered manually or on electrical fault.
- the closing command comprises, for each pole 20, the percussion plug 85 as well as a closing lock 126 constituted by a lever mounted idly on a bearing 128 carried by the hexagonal shaft 80.
- the closing lock 126 is returned clockwise in Figures 2 to 5 by a return spring not shown.
- Lock 126 has a arm defining a range 130 cooperating with the pin 85 and a second arm defining a curved surface and a rest surface, these two surfaces being intended to cooperate with the closing roller 77 of the control lever 60.

- the closing latch 126 In this position, the closing latch 126 is in its locking position, at the end stop running clockwise.
- the closing roller 77 bears on the curved surface of the lock 126 so that the moment, relative to the axis of rotation of lock 126, of the force applied by the roller 77 on the lock 126, tends to rotate the latter in the clockwise.
- the position of the lock 126 is therefore stable. Lock 126 prevents rotation of the control lever 60 clockwise.
- the opening spring 98 and the closing springs 106 are very weakly bandaged and recall the multifunction cams 88 and with them the camshaft 80, in the direction clockwise, the concave surface 90 being in contact with the opening roller 76.
- the spring of closure 106 also tends to rotate the crank lever 58 clockwise, but this movement is blocked due to the interaction between the control lever 60 and the closing lock 126.

- the camshaft 80 reaches an extreme position shown in FIG. 3, when the cocking cam 84 and cocking roller 96 reach a respective point position dead. In this position, the opening latch 116 has been released by the cam 92, so that the lock 116 has pivoted in the locked position under the action of its spring reminder 120.
