Definitions
- the present invention relates to a lock mechanism for electrical apparatus for line protection with differential function associated with circuit breakers.
- Such a lock mechanism conventionally comprises a plunger electromagnet adapted to cause the triggering of the lock mechanism when the coil is traversed by a current in case of imbalance in the currents carried by the conductors of the lines to be protected.
- This imbalance is in a known manner measured by means of a torus constituting the magnetic circuit of a transformer of which said line conductors form the primary, an electrical signal indicating an imbalance - and consequently a leakage of current in the protected electrical installation - being obtained in a secondary coil around the torus.
- the unbalanced signal appearing at the secondary is then classically sent to an actuator, where appropriate after passing through an electronic circuit ensuring a good shaping of the signal. It is this secondary signal, intended to trigger a resettable lock of the differential device itself connected to trip mechanisms tripping circuit breaker, q u i found in the aforementioned electromagnet, which in this case is the actuator.
- the lock mechanism of the invention comprises a connecting shaft that can take two positions respectively reset and triggered, and echoing the triggering of said lock mechanism locks circuit breakers.
- the reset button and the plunger are driven by a parallel translational movement, and are arranged to cause the displacement of a slide carrying the translational linkage shaft respectively in two opposite directions and in a direction perpendicular to the direction of their movement;
- a pawl is rotatably connected to said slider via a spring element urging it to establish a connection with a reversible transformation mechanical system of the translational movements of the button and the slider, said connection leading to a displacement of the slider against return means during the moving the button to its reset position;
- the plunger acts on the pawl during the trigger to break said connection, causing on the one hand the reverse movement of the slide urged by said biasing means towards a stop and on the other hand the return to the triggered position of the button under the effect his recall means;
- This configuration is particularly advantageous because it offers a very short kinematic chain, involving a double transformation translation / rotation / translation, and it guarantees proper operation including allowing a reset of the lock regardless of the position of the slide, as one will see it in more detail later.
- the mechanical reversible transformation system of the conjugate movements of the button and the slide consists of an intermediate rotating plate pivoting relative to the housing between two stops and mechanically connected on the one hand to the button and on the other hand to the slide by a double link reversibly transforming the translational movement of the button into a rotary movement of said plate and the rotary movement of the latter into a translational movement of the slide via a trigger member rotatably connected to the slide.
- Said trigger member and the rotary ratchet comprise respective profiles provided with first portions of surfaces of a shape perpendicular to the movement of the slider allowing a first support in the direction of said displacement during the reset, in order to place an end of said pawl in the trajectory of the plunger core, the displacement of which leads to pivot the pawl and release the support, causing the reverse movement of the slider and the button under the effect of their respective biasing means, the combined movement of the trigger member and the intermediate plate leading to replace the first portions of surfaces facing each other.
- the profiles of the trigger member and the ratchet comprise second portions of surfaces parallel to the movement of the slider, allowing a second support in the direction of movement of the button at the end of the trip in order to reposition the first surface portions facing each other after said tripping, biasing means being positioned between the pawl and the slider to urge the pawl in the direction of the second support.
- the first portions of surfaces which stiffen the ratchet / trigger member connection by allowing the support are more or less distant so that resetting is always possible, as will be shown in more detail in the rest of the text.
- the existence of these second surface portions ensures a correct facing of these first surface portions regardless of their distance.
- the link reversibly transforming the translational movement of the slider into a rotary movement of the plate is made of a first stud protruding from a first face of the plate, housed and guided in an oblong orifice of the trigger member oriented substantially parallel to the movement of the button in the support position with the pawl, the rotary displacement of the first stud in the orifice oblong resulting in moving the trigger member to the pawl during the reinitialization for pressing pressure of the first surface portions and spacing them from one another after the movements caused by the triggering .
- the axis of the first pad of the intermediate plate and the axis of pivoting of the triggering member are located on a line substantially parallel to the direction of movement of the button when the slide is in abutment at the end of trigger.
- the surface portions allowing the first support are then substantially in contact to allow the establishment of the rigid connection pawl / trigger member. There is no or almost no rotation when the latter is established. On the other hand, there is rotation in two opposite directions (see below) when there is triggering.
- the link reversibly transforming the translational movement of the knob into a rotary movement of the plate consists of a second stud protruding from the opposite face of the plate and housed on the one hand in an oblong hole of the button oriented parallel to the movement of the slider and passing through a semicircular slot of a wall integral with the housing, the ends of which constitute the stops of the movement of the button.
- the translational movement of the button is transformed, thanks to this double guidance, into a rotary movement of the aforementioned intermediate plate.
- This rotary movement is printed on the first stud which has been mentioned above, and communicated to the trigger member whose oblong orifice is maintained substantially in the axis of movement of the button when the link pawl / trigger member is established rigidly.
- the positioning of the slider is stable, and one of the ends of the pawl is then located under the plunger core of the electromagnet.
- a permanent magnet cooperates with the plunger to attract it in the absence of current in the coil, and return means of the core to the permanent magnet are provided to return said core in its reset position.
- these return means consist of a torsion spring with a spiral central portion disposed around a journal integral with the casing and radially projecting from two end branches, one of the branches being placed in a housing of the slide. and the other developing so as to intercept the trajectory of the mobile core.
- the return means of the slider and the reset button are coil compression springs.
- the lock mechanism of the invention comprises a spacer provided with a median wall and a base on which the slide moves, the button being guided in translation in a chimney made in the medial wall, the end the button protruding from the chimney towards the base on a first side of the medial wall having a guiding oblong hole-a stud protruding from the rotating plate pivotally mounted against the opposite side of the wall by means of a pivot housed in an orifice of said wall.
- Another stud protruding from the opposite face of said platen is inserted into an oblong orifice of the triggering member, said second stud traversing the oblong orifice towards the base during the reset, the axis of pivoting of said trigger member being located in the extension of the end of the oblong orifice located in the vicinity of the base and the profile ensuring the first and second supports being located in the vicinity of the opposite end of said oblong orifice.
- a return spring of the slide is integrated in a housing of the latter located near the base and exerts an action applied between the base and the stud inserted into the opening of the trigger member.
- This configuration makes it possible in particular to constitute the mechanical lock of the invention in the form of a compact and independent mechanical subassembly, positioned in the housing of each differential block.
- the spacer is indeed the support guaranteeing the position of all the components that have been reported so far, including for example the return means of the plunger core, the pin around which the spiral central portion of the torsion spring being a protrusion protruding from one side of the medial wall.
- the two half plastic shells only ensure the maintenance of all parts on the spacer.
- the slider which is in fact guided in translation by the base of the spacer, may then comprise a lateral lug guided in a slot in the median wall, which controls a switch indicating the state of the lock.
- the slider controls with a second leg the switches of the electronic card.
- said side tab may have the function of switching such a component during its translational movement in said light.
- other switches can be actuated using a second tab, allowing the control (supply) of the electronic card attached to the differential tripping device.
- the lock mechanism of the invention has a possibility of mechanical trigger, by action on a particular button assigned to this function.
- a mechanical test button which exerts an action on a drive member pivotally mounted on the central wall of the spacer, one end of which actuates a mechanical test slide guided in said wall along a path of pace parallel to the movement of the reset button and is connected to the latch to move it to break its mechanical linkage with the trigger.
- the other end of the drive member is connected to the central wall and comprises return means of said member in the initial position also able to return the mechanical test button to its initial position.
- This button acts directly on the ratchet unlike the latter.
- the drive member consists of a pivot from which two arms develop, the end of one of them driving the mechanical test slider, the other having an elastic corrugated portion is ending with an annular end surrounding with freedom of rotation a stud protruding from the median wall.
- the elastic portion is biased so as to accumulate the mechanical energy resulting from the actuation of the button, it restores in the absence of action on the latter, resulting in recalling the drive member and the test slider mechanical in initialized position.
- the end driving the test slider comprises a stud disposed free in translation in a transverse groove of the mechanical test slider, transforming the complex movement of said stud into translational movement of the slider.
- the mechanism of the invention can be constituted as an independent mechanical subassembly, arranged in a housing consisting of two assembled plastic half-shells which protrude from the connecting shaft (which is in direct contact with or via a transmission system with the locks of the associated circuit breakers, depending on their rating), the reset button and electrical connection wires. All the parts constituting the various functions of the lock are fully positioned by the spacer and held in place by the half-shells.
- This housing can indeed be implanted in different product sizes, obeying different calibrations (125-160 A, 160-260 A and 400-630 A).
- FIG. 1 - Figures 1 to 1 g show, in front elevation, a lock block according to the invention in different stages of operation;
- FIG. 1 is a rear perspective view
- FIG. 3 represents, in perspective, a view of the ram
- the block supporting the lock mechanism of the invention comprises a spacer (1), itself consisting of a median wall (2) and a base (3) on which moves in translation a slide (4) in a path limited in one direction by a stop (5).
- a reset button (7) is guided in translation in a chimney (8) formed in the median wall (2) of the spacer (1).
- This button (7) can be actuated downwards, against return means consisting of a compression spring (30).
- the displacement in translation of the button (7) drives a rotating intermediate plate (9) provided with a stud (1 0) (see FIG. 2) freely disposed in an oblong orifice (1 1) situated at the lower end of the button reset (7).
- the stud (1 0) moves in an opening (1 2) semicircular arc formed in one of the faces of the chimney (8).
- the rotating plate (9) comprises, on its other face, that which is on the side of the isseau (4), a second stud (1 3) which takes place in an oblong orifice (1 4 ') formed in a triggering member ( 14).
- This trigger member (14) comprises, at its upper end, a spout (15) providing a double support for a notch (31) of a pawl (1 6) rotatably mounted via a pivot (17) on the slider (4) .
- the trigger member (14) is also rotatably mounted via a pivot (18) on said slide (4).
- a return spring (6) urges the pawl (16) clockwise.
- return means (19) push the slide (4) in contact with the stop (5) (see Figure 3).
- An actuator (20) is arranged parallel to the reset button (7) in the middle wall of the spacer (1). It is in fact an electromagnet whose coil (21) surrounds a plunger core (22) which moves downwards in the event of imbalance in the currents of the conductors of the lines to be protected, that is to say when their sum is different from zero. This displacement is against a branch (23a) of a reset spring (23) whose other leg (23b) is connected to the slide (4). A permanent magnet (not shown) keeps the plunger core (22) in its rest position in the absence of defects in the protected lines.
- the slider (4) carries a connecting shaft (24) provided for triggering the attached circuit breaker locks, directly or via a linkage transmission system, in case of differential fault on the lines. It therefore exceeds the differential release device housing to cooperate with the contiguous circuit breakers.
- the translation of the slider (4) allows, as already mentioned, the actuation of several microswitches, for example for the power supply of the electronic cards, as well as for the display of the state of the lock (army or unarmed).
- the tab (28 ') is provided to drive, in the reset phase, the switching of a micro contact (27) reflecting the position of the isseau (4).
- the tab (28) protruding from a slider (4) and movable in the window (29) allows to actuate a signaling switch of the state of the lock (see Figure 2).
- the operation of the invention is as follows: when the user presses the reset button (7) against the spring (30) in order to reset the product, the rotating plate (9) is driven via the stud (10) in the oblong hole (1 1) (see Figure 2).
- This plate (9) is pivotally connected to the median wall (2) of the spacer (1), and the transformation of the translational movement into a rotary movement is allowed by the particular connection stud (10) / oblong hole (1 1 ) above.
- the stud (13) integral with the plate (9) housed in the oblong orifice (14 ') urges the trigger member (14) towards the right of the figure as it travels the oblong orifice (14 '), as shown in Figure 1b, and therefore drives the entire slide (4) because the trigger (14) is supported on the ratchet rotating (16) via the spout (1 5) applying in the notch (31) of said pawl (16).
- the translation of the slider (4) is exerted in this case against the spring (19).
- the reset button (7) exerts meanwhile - via its return means (30) in the triggered position, ie in the up position with reference to the figures - a force on the rotating plate (9) generating a torque that is exercised in the opposite direction, that is to say in the direction of clockwise since it is exerted to the left of said pivot axis of the plate (9).
- the turntable (9) is maintained in a low position, that is to say with the stud (13) at the bottom of the oblong orifice (14 ') of the trigger member (14) as shown in Figure 1b.
- the reset button (7) is also maintained in the low position, and the slider (4) is in the reset position, in this case to the left of the figure. In this position, the lock mechanism of the invention is armed, and the differential block is therefore ready to play its role.
- the contact (27) has changed position with respect to Figure 1a.
- the actuator (20) is controlled by the electronic cards, so that the plunger (22) descends towards the slide (4). This displacement takes place against the resetting spring (23), at least in its terminal phase, represented in FIG. 1c.
- the plunger core (22) strikes one of the ends (the left end in FIG. 1c) of the rotary pawl (16), causing it to rotate counterclockwise against the spring (6). .
- the spring (1 9) of the slider (4) then urges said slider (4) to the right of Figure 1 c.
- the mechanism for transforming translational movements into rotational movements operates in the opposite direction, due to the release of energy from the spring (1 9) on the one hand and - in a second step - under the action of the return means (30) of the reset button (7) on the other hand.
- the triggering organ (14) pivots around the pivot (18) first in a counter-clockwise direction (see Figure 1d), due to the placement of the stud (13) in the orifice (14 ') relative to the application of the return force due to the spring (19), said stud (13) then moving away from the lower end of the orifice (14 ') under the action of the displacement of the member (14) then continuing to slide towards the other end of the orifice (14 ') in a second step because the turntable (9) pivots in the direction of clockwise under the effect of the raising of the reset button (7). ) resulting from the action of the return means of said button (7) (see Figure 1 f).
- the key (1 6) is biased in rotation in the direction of the clockwise points, because action by its return spring (6) supported by one of its branches on the slide (4) , so as to restore the double-sided connection between the spout (1 5) and the pawl (1 6) when the spout (1 5) has exceeded the notch of the cliquet (16).
- the resetting spring (23) is compressed by the housing via the branch 23b due to the movement to the right of the slide (4) (see FIGS. g), and it pivots so that its branch (23a) in contact with the plunger (22) moves it upwards, towards the permanent magnet provided to maintain it in the rest position. Furthermore, the connecting shaft (24) secured to the slider has been moved in translation to the right of the figure, it has a direct or indirect action on the locks associated circuit breakers, which trigger. The arm (25) returns to its initial position, and reverses the contact (27) by means of the spring (26).
- the lock is now in the triggered position, the bearing surfaces of the spout (15) and the notch (31) repositioned to allow rearming.
- a mechanical test button exerts an action symbolized by the arrow F on a drive member (40) pivotally mounted about a pin (41) on the median wall (2) of the spacer (1), shown in rear view but without the reset button (7) for explanatory purposes.
- the end of the stud-shaped arm (42) actuates a mechanical test slider (44) guided in said wall (2) along a path parallel to the movement of the reset button (7).
- a point link is established between the latch (1 6) and the slider (44) for triggering the lock, when the sliding gate (44) rises under the effect of the rotation of the latch member.
- the connection between the arm (43) and the slider (44) takes the form of a stud (42) arranged freely translatable in a groove (46) cross section of said mechanical test slider (44).
- the other end of the driver (40) is fixed with a degree of freedom in rotation with respect to the medial wall (2), by means of a ring placed at the end (47) of the arm ( 45) and surrounding a stud (48) protruding from the medial wall (2).
- Return means of said member (40) in the initial position, in the form of a resilient corrugated portion (49), are provided to return the mechanical test button (40) to its original position, as well as the button mechanical test, in the absence of solicitations.
