Definitions

  • the invention relates to a switch for low voltage power, provided with a trigger mechanism.
  • a bistable sub-assembly 200 composed of a lever 202 and a connecting rod 204 articulated by an axis 206, is urged by an accumulation spring 207 between a stable open position limited by an opening stop 208 and a stable closing position limited by a closing abutment 209, passing through an unstable neutral position in which the spring 207 is loaded to the maximum.
  • the lever 202 drives a contact bridge 210 with knives 212 between a contact position and a separation position, via a connecting rod 214. In the contact position, the knives 212 of the contact bridge 210 are deeply inserted into contact clamps 215 connected to the connection pads of the switch.
  • the connecting rod 214 is provided with an oblong 216 , so that when the contact bridge 210 is in the contact position and the mechanism in the closed position, it is possible, without moving the contact bridge, to bring the lever 202 with a handle 218 from the closed position to beyond the neutral position. In this way, the spring was loaded before the separation of the contacts and one benefits from all the energy accumulated to suddenly open the apparatus.
  • Mechanisms for rapid opening are also known. These are typically the circuit breaker mechanisms, which has been shown a schematic diagram on the figure 2 .
  • Such a mechanism comprises an upper connecting rod 220 and a lower connecting rod 222 forming a toggle joint 224 connecting a hook 226 to a contact bar 228.
  • the hook 226 pivots about a fixed axis 227 and is retained by a lock 230 in a lock position.
  • a handle 232 pivoting about a fixed geometric axis 234 is connected to the hinge axis 236 of the toggle joint 224 via an accumulation spring 238.
  • the latch 230 When it is necessary to separate the contacts without maneuvering the handle, especially in the event of a short circuit or electrical fault, the latch 230 is operated which releases the hook. The residual charge of the accumulation spring 238 in the closed position is then sufficient to drive the contact carrier 228 in the separation position, the mechanism then being in a triggered position.
  • Such a mechanism responds to the need for a quick remote opening maneuver without motorization.
  • it is not suitable for an apparatus requiring significant mechanical energy at closing, because by unfolding and folding, the toggle 224 never passes on both sides of its dead point corresponding to the alignment of axes of the upper link 220 and the lower link 222. In the closed position shown on the figure 2 the equilibrium is obtained by the residual tension of the accumulation spring, which also dictates the contact pressure.
  • the closed position is not absolutely stable in the sense that, by applying a sufficient effort on the contact door to open the contacts, we can fold the knee 224.
  • To increase the electrodynamic strength it is necessary to strengthen the accumulation spring and consequently all parts of the mechanism that are subject to deformation and greater wear. Therefore, this type of construction is largely unsuitable for devices requiring strong electrodynamic resistance.
  • the document DE-C-19507605 discloses a mechanism for electrical cut-off apparatus with a disengageable transmission kinematic chain.
  • the invention therefore aims to overcome the drawbacks of the state of the art, so as to provide an electrical switchgear ensuring the passage of a very high permanent current, while allowing a quick opening operation and low energy, lending itself for example to a remote control.
  • bistable sub-assembly ensures the irreversibility of the closed position, thus the guarantee of a high electrodynamic resistance.
  • the possibility of disengaging the disengageable transmission chain makes it possible to release the contact door and to make it independent of the bistable subsystem, which is by nature too slow to allow a fast and low energy maneuver.
  • the mechanism further comprises means for driving the movable contact carrier from the contact position to the separation position when the disengageable transmission kinematic chain is in the disengaged state.
  • the means used can be of all types, motorized or not.
  • the means for driving the contact carrier comprise a trigger transmission kinematic chain, arranged between the accumulation spring and the contact holder, so that when the disengageable transmission kinematic chain is in the When engaged, the trigger transmission kinematic chain does not transmit the movement of the movable contact carrier between the contact position and the separation position to the accumulation spring and when the disengageable transmission kinematic chain changes from engaged in the disengaged state, the accumulation spring discharges by driving the movable contact carrier from the contact position to the separation position via the trigger transmission kinematic chain.
  • the accumulation spring which carries out the opening and closing via the bistable subassembly is also used for the opening by disengaging.
  • the means for driving the mobile contact carrier further comprise an additional spring.
  • the accumulation spring and the additional spring together effect the opening by disengaging.
  • the additional spring only accumulates additional energy so that the storage spring does not have to provide all the fast opening energy.
  • the additional spring alone provides all the energy necessary to separate the contacts during the disengagement, which avoids the installation of a chain kinematic transmission trigger between the accumulation spring and the contact holder.
  • the mechanism further comprises a disengaging latch locking the disengageable transmission kinematic chain in the engaged state.
  • the disengageable transmission chain can be brought into the disengaged state by various means: return spring, ramp, etc.
  • the mechanism further comprises an opening latch locking the means for driving the movable contact carrier.
  • the two locks coexist and the opening lock also locks the release lock, so that a single order can control the entire mechanism.
  • the disengagement lock is moved by the means for driving the mobile contact carrier. Then, to operate the release latch, the energy of the means for driving the movable contact carrier is used when the disengageable transmission kinematic chain is in the disengaged state, ie for example the energy of the accumulation spring or the additional spring, as the case may be.
  • the positioning of the spring between the hinge and the hook makes it possible to use both ends of the spring as a moving motor part.
  • the bistable subassembly it is the end of the spring side articulation that applies the mechanical work.
  • the triggering phases it is the end of the hook-side spring that becomes mobile. The timeline obtained during the triggering allows a reliable command initiated by a lock.
  • the contact holder supports at least a first contact cooperating with a second contact and forming with the second contact a pair of clamp contacts and knives.
  • the first contact may be secured to the contact holder.
  • a low power voltage switch comprises a contact bridge 10 movable in rotation about an axis 12 and provided with two movable contacts 14, cooperating with fixed connection contacts 16 connected to the connection pads of the switch.
  • the contacts 14, 16 are of the knife and clamp type.
  • the contact bridge 10 is driven by a mechanism driven by an accumulation spring 20.
  • a frame 21 supporting the mechanism and shown purely schematically in the figures, defines a fixed geometric reference.
  • the geometric axis 12 of rotation of the contact bridge is fixed in this frame of reference.
  • the mechanism comprises a bistable subassembly 22 formed by a connecting rod 24 articulated on a bistable lever 26 at an axis 28.
  • the connecting rod 24 forms an oblong 30 in which slides a slide 32 secured to a hook 34 for controlling the mechanism and extended by a projecting free end 36.
  • the accumulation spring 20 is a compression spring whose one end cooperates with the connecting rod 24 near the hinge 28 and whose other end is supported on the control hook 34.
  • the stroke of the hinge 28 is limited on one side by a fixed closing abutment 38 and on the other by a fixed opening abutment 42.
  • the hinge 38 also co-operates with an arm 40 of the control hook 34, in a plane different from that where the stop 42 is located.
  • a slide 44 secured to the lever 26 is guided in a slot 46 integral with a handle 48 for operating the mechanism.
  • the slot 46 forms a link to travel limited on one side by an abutment 50 and on the other by the end edge of the slot, a return spring 52 tending to move the bistable lever 26 away from the abutment 50.
  • the handle 48 and the bistable lever 26 are pivoted around the same fixed geometric axis 53.
  • the bistable subassembly 22 is connected to the contact bridge 10 via a disengageable subassembly 54 composed of a rod 56, an upper bar 58 and a lower bar 60.
  • the upper bar 58 is a lever pivoting about a fixed geometric axis 62, connected to the bistable lever 26 via the rod 56 and provided with an end projection 64.
  • the lower bar 60 has a groove 66 cooperating with the projection 64 the upper bar 58 to form a disengageable coupling 68.
  • the connection between the lower bar 60 and the contact bridge 10 is formed by an oblong guide slot 70 cooperating with a slide 72 integral with the contact bridge 10 and allowing a clearance of the bridge 10 relative to the lower bar 60.
  • the hook 34 pivots around a geometric axis 74 fixed relative to the frame of the apparatus and its free end is provided with a roller 76 locked in position by a cam 78 retained integral with a main latch 80 of the mechanism, and even locked by a control lock 82.
  • the main lock pivots about a fixed geometric axis 83 and is biased by a return spring 84 clockwise in the figures.
  • the main latch 80 cooperates with the lower bar 60 via an oblong guide 86.
  • a trigger bar 88 connects the hook 34 to the contact bridge 10, via a slide 89 guided in an oblong guide 90.
  • the control lock 82 is itself controlled by an electromechanical relay 92 and provided with an extension 94 cooperating with the free end 36 of the connecting rod 24 of the bistable sub-assembly 22.
  • a spring blade 96 integral with the handle 48 is arranged so as to be in the path of the hook 34.
  • An optional additional spring 98 is disposed at the hook 34, to bias the hook 34 to the disarmed position.
  • the device operates as follows.
  • the apparatus In the position shown on the figure 3 , the apparatus is in an open armed state undesirable.

  • the additional spring 98, if it exists, is loaded.
  • the storage spring 20 is partially loaded.
  • the link 24 of the bistable subassembly maintains at its free end 36 the control lock 82 in the locked position so that this position would not be affected if an opening command was transmitted to the electromechanical relay 92.
  • the main lock 80 is therefore itself locked in the locking position and acts on the lower bar 60 so as to maintain the disengageable subassembly 54 in an engaged state, the projection 64 of the upper bar 58 being engaged with the groove 66 of the lower bar 60.
  • the handle 48 is in the open position, and the slide 44 held by the return spring 52 against the edge of the slot.
  • the slider 72 comes into abutment at the end of the light 70, so that the lower bar 60 begins to drive the contact bridge 10 to the contact position.
  • the moving knife contacts 14 penetrate into the clamps 16 and while the transmission kinematic chain continues its movement under the impulse of the accumulation spring 20, until the hinge 28 meets the closure stop 38. the closing phase, the trigger bar does not intervene because of oblong 90 which leaves a sufficient clearance.
  • the potential energy of the accumulation spring 20 is therefore entirely dedicated to closing the contacts. It should also be noted that in the closed position the slider 89 has not reached the end of the oblong guide 90.
  • the pliers 16 and knife contacts 14 admit a range of positioning of the knives relative to each other. to the claws. In this way, the games, tolerances and wear of the parts of the mechanism, which tend to change over time and from one device to another the position of the knives 14 in the clamps 16 when the mechanism is in the closed position defined by the closure stop, have no effect on the quality of the contact obtained.
  • the closing abutment does not need to be positioned with great precision.
  • the main latch 80 then drives the lower bar 60 so that the projection 64 of the upper bar 58 disengages from the groove 66 of the lower bar 60, thereby passing the disengageable subassembly 54 in a disengaged state.
  • the hook 34 biased by the accumulation spring 20, then becomes free to drive the contact bridge 10 via the trigger rod 88, to the separation position shown on the figure 6 . Arriving in this position, the hook 34 interferes with the spring blade 96 so that the handle 48 is pushed back until stopped by the stop 50, in a position indicating the triggered open state of the apparatus.
