Definitions
- the present invention relates to a system for signaling an electrical fault in a breaker-type circuit breaker device.
- system of the invention preferably indicates the occurrence of a differential defect in a circuit.
- the switching devices concerned by the invention usually comprise: a mechanical trigger lock associated with at least one pair of respectively fixed and movable contacts, transmitting the movement of a control handle to each moving contact in order to move it between two stable positions, respectively in support of and at a distance from a fixed contact;
- the signaling system of the invention furthermore comprises an indicator means which signals the appearance of a fault and which must also memorize the information until reset, by manipulation of the joystick.
- the signaling system of the invention is mechanical, not electrical operating in dependence on a power source of the electrical installation that the circuit breaker protects.
- patent FR-2 767 602 gives in particular an example of a structure comprising a means for holding the indicator towards a visible position against the action of a means of recall in an invisible position, so as to memorize the trigger action until a closure maneuver of the device.
- the indicator retaining means comprises a slide driven in translation by the control lever between a rest position and a retaining position of the indicator.
- Such a system requires to conform the indicator, rotatably mounted around a fixed axis of the device, so that one of its ends cooperates with the drawer. The latter is itself subjected to return means in a rest position in the absence of defects.
- This mechanical system integrates several components according to a kinematic chain simultaneously involving rotating parts and parts in translation. The multiplication of parts is not a favorable index in terms of reliability of the assembly, and it also complicates the mounting of the device. From an economic point of view, these parameters can be seen as unfavorable.
- the signaling system of the invention essentially comprises a moving part combining several functions.
- the signaling system of the invention applying to breaking devices as described above, is characterized in that it comprises a signal piece driven by the core of the electromagnet and having a signaling surface capable of moving in relation to a window made in the front of the device and a pin designed to trigger the lock in case of displacement of the core when a defect is detected by the detection device and control, a retaining relief and a corresponding recess being provided respectively on said signal piece and on the control lever or on a component which is integral therewith, their relative positioning resulting in blocking the signaling piece after displacement of the core caused by the electromagnet, the lever being in the open position of the contacts.
- the system of the invention involves only a single piece, at the same time signaling and blocking, the latter being made possible by the existence of the relief / recess couple.
- the relief may be a lug placed on the signal piece and the recess may take the form of a cam on the control lever or on a component which is integral therewith.
- a reverse configuration could of course also be implemented.
- said signal piece can be driven in translation and comprise a fixing hole in the core of the electromagnet, a first radial arm having the trigger stud, a second axially-oriented arm comprising the pin blocking, and a wafer developing parallel to the first arm and having the signaling surface.
- the second arm is offset with respect to the axis of the core.
- it develops from the first arm.
- the signaling piece can be rotated and comprise, as far as possible, a peripheral wall in the form of an arc of a circle bounded by two walls of radial shape, whose IQne comprises a hole of attachment to the core of the electromagnet, the trigger pin being oriented parallel to the axis of rotation and protruding from the room at the other one of the radial walls.
- the end of the latter further comprises a plate having the signaling surface, the locking pin then being provided on the periphery of the arcuate wall.
- the lug cooperates with a cam integral in rotation with the control lever.
- this cam is disposed at the periphery of a component attached to the control lever, and it consists of a protrusion positioned such that in the open position of the contacts, said protuberance interferes with the path of the ergot retaining and blocks the return of the signaling piece impelled by the return means of the core, after detection of the defect.
- the cam is placed in the locking position due to the tilting of the lock, tilting obtained by the movement of the signal piece.
- the return means act to return the core, and therefore said signal piece, in their initial position, the lug meets the protuberance of said cam, and is therefore blocked.
- the signaling surface is positioned in front of the window made in the front of the device, and therefore indicates that the opening of the breaking device results from a differential fault indicated by the electromagnet of the device. differential stage.
- the return means consist of a compression spring interposed between the yoke of the electromagnet and the signal piece fixed on the movable core.
- This spring in principle returns well the assembly consisting of the signal piece and the movable core in its initial stable position in the absence of defect.
- this spring fulfills its function correctly only if the control lever is not in the open position of the contacts. In other words, when the apparatus is reset, in order to close the contacts, the cam integral with the rotation of the control lever is moved away from the path of the signaling piece, allowing the spring to perform its function and the signal piece and core to resume their original position.
- the invention applies in particular to a differential circuit breaker, provided with a signaling system as explained above, and which comprises a partition separating the circuit breaker part and the differential function part, to which part belongs moreover the electromagnet.
- the partition is also provided with a light for the passage of the trigger pin of the signal piece, the component provided with the cam attached to the handle is also arranged on the side of the differential part.
- FIG. 1 shows, in perspective, a differential circuit breaker constituting an example of a switchgear that can be equipped with a signaling system according to the invention
- FIG. 2 shows in perspective view a signaling part according to the present invention
- FIG. 3 is a partial perspective view of the differential circuit-breaker of FIG. 1, showing in particular the cooperation between the electromagnet and a translative signaling piece according to the invention;
- FIG. 6 is the equivalent of FIG. 3 with a rotating signaling piece configuration
- FIGS. 8 and 9 are views similar to the views of FIGS. 4 and 5 showing the respective positions of the rotary signaling piece in Itabsence and in the presence of a differential defect.
- the differential circuit breaker comprises a molded plastic housing (1) which exceeds a control handle (2) whose two stable positions respectively correspond to the closure and opening of the contacts.
- Input and output connection means (3) and (4) allow insertion of the differential circuit breaker into a circuit.
- the housing (1) therefore contains a circuit breaker function and a differential fault detection function.
- the position of the control handle (2) shows that the breaker part is located in the left half of the product, while the differential part is in the right half.
- This is provided with a window (5) with which the signaling system of the invention cooperates.
- This system is based on a signal piece (6), an example of which appears in FIG. 2 in a mobile version in translation. It comprises an orifice (7) provided for its attachment to the movable core (see Figure 3) of the electromagnet.
- a first arm (8) is oriented radially with respect to the orifice (7).
- a second arm (10) develops from the first arm (8), whose free end is provided with a pad (11) of triangular shape.
- the piece (6) is further provided with a plate (12) whose apparent surface (13) is provided with a means for signaling a differential defect.
- the signaling piece (6) of the invention is fixed to the end of the movable core (17), a compression spring (19) being interposed between the left side wall of the magnetic yoke (18) and a flange (20). ) surrounding the orifice (7).
- the trigger pin (9) not visible in this figure, slides in a slot (21) formed in the partition (14).
- the core (17) dips inside the coil (16), moving at the same time the entire part (6) and in particular the plate (12) and its signaling surface (13). It then moves so as to face the window (5) made in the front of the differential circuit breaker box, in the cover of the latter (see Figure 1).
- the information is stored, the wafer (12) remaining in its position after disappearance of the differential defect because the piece (6) is retained in the position corresponding to the dive of the movable core (17) inside the coil (16). ) due to a cam (23) fitted to the periphery of a component (22) integral in rotation with the control lever (2), and which protrudes from the differential side of the partition (14).
- FIGS. 4 and 5 show the part (6) and the control handle (2), and consequently the component (22), in a position respectively reflecting the absence of differential defect detection and the presence of such a defect.
- the position of the control handle (2) reflects the closure of the contacts.
- the cam (23) is located near the front of the housing (1), and the entire part (6) is at a distance from the coil, in the initial rest position.
- the core (17) plunges towards the coil (16), driving the part (6).
- the arm (10) and the stud (11) therefore move in direction of the arrow (F), to the right of the figure.
- the cam (23) in this case interferes with the path of the stud (11) and retains the latter, preventing the return of the workpiece (6) to the initial resting position under the effect of the return means, namely the spring ( 19).
- the signaling surface (13) is in front of the window (5), which is not the case in Figure 4.
- a variant with a rotary configuration is based on a part (6) having essentially a wall (25) in an arc of a circle on which is positioned a blocking pin (11 [1, and two walls radial (26) and (27) bounding the arc wall (25), the first having an orifice (7 [Jl fixing the core of ISIectroaimant while the second has the stud (9IJI tripping.
- the pin (9 ') triggers the lock, opens the contacts, and tilts the lever (2) in the position shown in FIG. 9.
- the cam (23) on the periphery of the component (22) moves to block the return of the workpiece (6 '), since the spur (11') then encounters said cam (23) when the spring recalls the core (17) in its initial position.
- the differential fault is then stored until manual switching of the handle (2) in the closed position of the contacts.
