Definitions

  • the present invention relates to a lock mechanism for a contactor-limiter, of the type comprising, in a manner similar to that described in French patent FR-A-2 570 872 filed in the name of the applicant and having served to delimit the preamble of the independent claims 1 and 2 of the present application, at least one set of switches which can be actuated on closing and on opening by a control electromagnet, which constitutes its contactor function, or even on opening alone by a device which, associated with an overload detector, ensures rapid opening corresponding to the limiter function.
  • the limiter function has priority over that of the contactor, which means that in the event of closing on a short circuit, the opening process of the switches must be carried out as quickly as possible.
  • the opening command of the switches is carried out by an appropriate mechanism, the interruption of the supply of the electromagnet intervening only to confirm the interruption.
  • An object of the invention is to provide a mechanism of the kind described in the aforementioned French patent which is extremely reliable and quick to operate, while being relatively inexpensive.
  • An object of the invention is also such a mechanism which can also be associated with a reversing contactor-limiter produced by two contactor-limiters mounted side by side.
  • An additional object is a mechanism of this type which can take three stable positions, namely "stop”, “on”, “triggered” and a transient reset position.
  • a lock mechanism for a contactor-limiter comprising two sets of power switches, each being actuated on closing and on opening by a control electromagnet by means of a push block on each of which also acts the lock mechanism by occupying at least two stable positions: a locked position of automatic operation which authorizes the closing of the sets of switches by the control electromagnets and a triggered position in which the mechanism lock maintains the two sets of switches in the open position, the passage from the locked position to the tripped position being effected vigorously.
  • the invention also relates to a lock mechanism for a contactor-limiter as described in claim 2 in which the two levers act on the same push-button.
  • the movable contacts of the switches can be brought into the normally closed position by means of return springs and actuated by the action on the push-button of an electromagnet ensuring the contactor function.
  • the rotary cam is mounted freely on a second axis perpendicular to the first parallel axes of said first levers and has a heel which allows it to be kept in said locked position by a first trigger capable to be erased to release the cam which is then brought back energetically into said triggered position by means of elastic means which are applied to the first two levers.
  • each of the levers specified above has the shape of a Z, it is articulated in the vicinity of a bend of the Z, its free end located on the side of its articulation carries a corresponding roller , and its other free end is located opposite the pusher block. Thanks to this arrangement, an energetic and well-multiplied action is obtained on the push-pieces and their switches.
  • the cam of the mechanism according to the invention has the shape of an S, and its rollers are supported on its outer contour.
  • the axis of rotation of this cam is integral with a control button at one end, which carries three locking and control cams and which is returned to a "stop” position by a helical spring which surrounds it. It is by turning this button that the mechanism is moved to the "stop", “automatic” and “reset” positions.
  • this control button can be secured to a first finger capable of pushing the rotary cam towards its locking position, position in which it engages the first trigger and is locked in rotation.
  • the rotary cam can then be released by actuating this first trigger by means of one or more fault detection relays.
  • the central axis of the device specified above carries a first control cam whose periphery has a notch into which can penetrate, under the action of second elastic means, a second finger mounted on a second lever which ensures, in this position, the closing of a switch mounted in series with the electromagnet excitation circuit serving to ensure the "contactor" function. This corresponds to the "automatic operation" position of the device.
  • the mechanism according to the invention comprises a cleat which is pivotally mounted on a third fixed axis against a spring and which can be blocked by two triggers each of which can be unlocked by a relay. fault detection.
  • One of these triggers can be the one which also blocks the main S-cam specified above and which is controlled by a fault detection relay, while the other is controlled by another fault detection relay, a link may or may not exist between these two triggers.
  • the mechanism according to the invention serves to open and close two sets of three switches 1a and 1b, the movable contacts of each group being actuated simultaneously by a pusher block 2a or 2b, respectively.
  • the latter pushes the three corresponding contacts in the direction of the opening shown in the figure, and this against springs 3a or 3b which tend to recall their respective groups of movable contacts 1a and 1b in the direction of closing.
  • the members associated with the two push-pieces 2a and 2b are symmetrical, and, for reasons of simplification, they will be designated by the same reference mark whether or not followed by the letter a or b, respectively.
  • Each pusher block 2 can be pushed or released by an electromagnet A or B by means of a lever A ′ or B ′ and against a spring A ⁇ or B ⁇ , the switches 1 closing when the corresponding electromagnet is excited.
  • Each pusher block 2 can also be pushed towards the switches 1 by one end of a lever 4.
  • this lever has the shape of a lying Z, and it is articulated around an axis 5 which is perpendicular to its plan and which is located in the vicinity of the point of Z opposite the pusher concerned.
  • the other end of this lever 4 carries a roller 6 whose axis extends substantially in the plane of the lever and in the extension of the branch of the Z which carries it.
  • Each of the two rollers 6 rests on a rotary cam 7 which is common to them, which extends substantially in the plane of the rollers 6 and which is freely mounted on an axis 8 perpendicular to the axes 5.
  • the rollers 6 are applied to the profile of the rotary cam 7 by tension springs 9, and are each guided in their movements by a disc D, respectively D ′ Which runs freely on a raceway R, R ′ parallel to the axis of the rollers.
  • a rotary control button 10 can be made integral with the other end of the axis 8 which can thus be rotated as indicated by the arrow F1 against a helical return spring 11 which surrounds it and which tends to bring it back to the "stop" position.
  • the axis 8 is integral with a cam 12 with three tracks perpendicular to the axis, and with a finger 13 which is parallel to the axis 8 and which projects in the plane of the rotary cam 7.
  • FIGS. 2 to 5 we find the push-pieces 2 of the switches 1, the levers in Z, 4 and, this time in exploded top view, the rollers 6 according to the external profile of the rotary cam. 7. Also seen, also in top view, tracks 14, 15 and 16 of the three-track cam as well as the control button 10 in its four positions. The axis 8 which connects the latter to the cams 14, 15 and 16 is shown diagrammatically by a vertical mixed line.
  • the trigger cam 7 has substantially the shape of an S mounted in its center on the axis 8, so that its width, taken along a fixed line contained in the plane of Figure 1, can go from a small value ( Figure 4) where the rollers 6 are close to each other, to a greater value ( Figures 2, 3 and 5) by spreading the rollers 6 from each other and pivoting towards the outside, against the springs 9, the branches of the Z-shaped levers, 4 which carry the rollers 6.
  • the opposite branch of the Z deviates from the associated pusher block 2, that the latter deviates from the movable contacts of the switches 1, and that these close under the effect of the springs 3.
  • the triggering cam 7 can be blocked by a spout of a trigger 17 which engages in a heel 18 formed in the external profile of the cam 7.
  • the trigger 17 is articulated on an axis 19 perpendicular to the plane of the cam 7, while its beak, pushed towards the latter by a spring 20, can be released from the heel 18 by a fault detection relay, not shown, which rotates the trigger in the direction of the arrow F2, against spring 20.
  • a cleat 21 is articulated on a pivot 22 parallel to the axis 8, at a distance therefrom and against a return spring 23. It has a finger 24 which is directed towards the axis 8 and which bears, under the effect of the spring 23, on the cam 14.
  • the latter successively comprises: a heel 25 against which the finger 24 abuts to block the axis 8 in an angular position corresponding to the "stop" position "against the action of the spring 11, and a circular portion allowing a rotation of a quarter of a turn of the axis 8 in a clockwise direction from the" off "position.
  • the cleat 21 further comprises an arcuate extension 28 which surrounds the axis 8 over a quarter of a circle approximately, opposite the finger 26, and which comprises an outer heel 29 capable of engaging with a beak of a second trigger 30.
  • This spout is pushed towards the heel 29 by a spring 31 and it can be erased by rotation of the trigger 30, against this spring 31, under the effect of another non fault detection means shown which acts in the direction of arrow F2 ′.
  • the two triggers 17 and 30 are secured in their movements by a lever 32, and a judicious calculation of the lever arms makes it possible to have on each of them a different tripping force and adapted to the fault detection means used, for example , to a thermal or magnetic protection relay, or to an undervoltage or voltage transmission relay.
  • the cleat 21 also has a shoulder 33 into which a rod 34 secured to the trigger 17 can penetrate.
  • the cam 16 secured to the axis 8 has, on its periphery, a rectangular notch 35 into which a finger 36 can penetrate which is formed at one end of a lever 37 articulated at 38, and which is pushed towards the cam 16 by a spring 39.
  • the other end of the lever 37 carries a pusher 40 which acts on the movable blade 41 of a switch 42 placed in series in the supply circuits of the coils of the electromagnets.
  • a pin 43 integral with the cleat 21 can rotate the lever 37 in the direction where the finger 36 comes out of the notch 35 of the cam 16.
  • the lever 37 in the elbow which it forms in line with the finger 36, has a recess 44 which is open towards the outside on the side of this finger by a narrow channel 45.
  • a loop spring 46 is housed in the recess 44, and its two ends are anchored in the walls of the lever 37, so that it tends to close the channel 45 against the elasticity. clean of the thermoplastic molded material which constitutes the lever in question.
  • FIGS. 2 to 5 correspond respectively to the "stop”, “automatic”, “triggered” and “reset” positions of the control button 10, these positions of the button being shown on the left side of each figure.
  • the cleat 21 is fixed in rotation in both directions by the spouts of the two triggers 17 and 30.
  • the finger 36 of the lever 37 rests on the periphery of the cam 16, at the outside of the notch 35, so that the switch 42 is open and the electromagnets A and B are not energized.
  • the push-pieces 2 are therefore pressed on the switches 1 by the levers A ′ and B ′, and the switches 1 are open.
  • the Z-shaped levers, 4 are separated from the push-pieces 2 by the cam 7, by means of the rollers 6, because the cam 7, in line with the latter, has its greatest width and is blocked by the trigger 17 in engagement with its heel 18, as well as by the finger 13 secured to the control button 10.
  • the recess 44 of the lever 37 and its loop spring 46 serve to allow correct hooking in the "automatic” position without hampering the triggering: during a maneuver of the button 10 towards the "stop” position, the notch 35 of the cam 16 biases downwardly the finger 36 held in abutment by the spring 39, and this, until exhaust, tilting of the lever 37 and opening of the switch 42.
  • the S-cam, 7 can rotate under the effect of the rollers 6 on which the springs act 9.
  • the rollers come together, which causes the free ends of the levers in Z, 4 to move towards the blocks- pushers 2 and to open the switches 1.
  • the switch 42 opens, which removes the supply of electromagnets A and B which also press push-buttons 2 to open switches 1.
  • the device which has just been described in its application to a reversing contactor-limiter device can be applied to a simple contactor-limiter, by replacing the push-buttons 2a and 2b of FIG. 1 with a single push-button 2 shown on Figure 6 on which act the free ends of the two levers in Z, 4a and 4b.
  • FIG. 7 represents means for the execution of an additional function called "verification of the opening positivity", and which use an unlocking cam 50 driven in rotation by the control button 10.
  • a lever 51 articulated at 52 and pushed by a spout 53 of the release cam 50 the latter acts on the push-button or blocks 2, independently of the rest of the mechanism, which, by forced action on the button 10, makes it possible to '' remove foreign bodies or overcome possible jams.
