Definitions

  • Differential switches or circuit breakers including means for signaling a differential fault in order to enable the user to detect the presence of an insulation fault in his electrical installation.
  • Some of the known signaling means are in the form of LEDs (light-emitting diode systems or other LEDs) operating under the control of the power source of the electrical installation that the circuit breaker protects.
  • LEDs light-emitting diode systems or other LEDs
  • the differential trip unit comprises a transformer and a relay cooperating by means of a trip bar with the lock of the mechanism, and with a signal lock of a fault indicating lever.
  • the relay used is a relays with two stable positions, magnetic latching type. However, this type of relay is relatively expensive and this switch implementation implements a large number of parts.
  • EP 0208614 describing a current limiter provided with an opening memory indicator biased by a spring, for storing the trigger information.
  • the present invention proposes a fault signaling device for a switching device including a differential circuit breaker, simple design, operating independently of the power source of the installation and moreover auto-resettable, and a switch or circuit breaker equipped with this device.
  • the present invention relates to a device of the kind mentioned above, according to claim 1.
  • the indicator is driven positively by the electromagnet between the two aforementioned positions.
  • the aforementioned tripping means is a dipping core electromagnet and the indicator is driven positively by the core dipping between the two aforementioned positions.
  • the present invention also relates to a switchgear and in particular a switch or differential circuit breaker equipped with a device comprising the preceding characteristics taken alone or in combination.
  • a differential circuit-breaker D is seen housed in a parallelepipedal casing 1 made of molded insulating material intended to be snap-fitted on a DIN rail (no represent).
  • This circuit breaker D is intended to be connected in an alternating network by means of connection terminals provided in the housing 1 and can fulfill several functions. It can indeed trigger, and thus interrupt the electrical circuit, when the occurrence of an overload, a short circuit or a differential fault.
  • This circuit breaker D comprises means M signaling a differential fault enabling the user to diagnose that his electrical installation has an insulation fault and not an overload fault or a short circuit fault. With this means of signaling, the user is immediately operational to search for the lack of isolation, whereby the safety of people and goods can be effectively maintained.
  • this apparatus in its two embodiments, comprises a pair of contacts (not shown) separable by pole, a control mechanism of the two contacts comprising a handle 2 connected by a mechanical transmission link to an organ driving the contacts, an operating spring of the mechanism (not shown) to cause the opening of the contacts during an automatic fault trip, a differential trip unit having a leakage current detection transformer and an electromagnet 11 for cooperating with a latch of said mechanical linkage of the mechanism.
  • This electromagnet 11 comprises a plunger core 8 intended to slide in a guide tube formed by the carcass of a coil when it is traversed by a current, between a rest position FIGS. 1, 3 and 9, 11a and a position Trigger activates Figures 2, 4, 10 and 11.
  • the signaling means M comprises an indicator 5 in the form of a rod articulated around a fixed point 9 of the apparatus, said rod 5 being connected in an articulated manner by one its ends to the core 8 of the electromagnet 1 and having at its opposite end, a sight 16 for cooperating with a window 13 provided at the upper part of the housing 1.
  • the indicator 5 also comprises a lug 14 adapted to cooperate with a stepped portion 15 of a slide 3 slidably mounted inside the housing 1 parallel to the displacement of the core 8.
  • This drawer 3 is driven to slide by the handle 2 between a rest position fig. 1 and an active position fig.2 which will be described later.
  • the handle 2 comprises a connecting lug 4 adapted to drive the drawer 3 after a certain closing stroke of the handle 2.
  • a spring 6 is interposed between the drawer 3 and the housing 1 in order to recall the drawer 3 in rest position.
  • the signaling means M comprises the same elements as previously described, but the indicator 5, articulated around the fixed axis 9, comprises a first end 5a cooperating with the retaining means 3 and a second end 5b connected to the core 8 of the electromagnet 11, so that the indicator 5 is driven by the core 8 in the direction of the trigger and moves in rotation relative to said core during the reset of the latter.
  • the signaling means M further comprises a spring 12 adapted to recall the indicator 16 to a rest position after a closing operation of the contacts.
  • the circuit breaker D being closed (FIG 1 and 3), the circuit breaker and differential mechanisms are locked and the indicator 16 is cleared, ie not visible through the window 13, because held in position by the piece 7, itself retained by the core 8 of the differential release system.
  • the indicator 5 and the indicator 16 pivot about the axis 9.
  • the lever 2 released from the latching circuit-breaker, and equipped with the connecting piece 4 acts on a mechanism that drives the drawer 3, which, thanks to the release of material 15 by moving from left to right (arrow B), locks the lug 14 of the indicator, and thus keep it in the "visible” position (FIG. 2 and FIG. 4).
  • the spring 10 of the electromagnet 11 pushes the core 8 in the rear position and thus returns the differential assembly in the working position.
  • the action of the return spring 6 pushes the drawer 3 in the rear position and thus unlocks the indicator 16.
  • the device is then in the working position and able to fulfill its role.
  • the circuit breaker D being closed, FIG. 9, the circuit breaker and differential mechanisms are locked and the indicator light 16 is erased.
  • the indicator 5 and therefore the light rep. 16 rotates about the axis 9.
  • the lever 2 released from the latching circuit breaker side, and equipped with the piece or lug 4, comes to support the drawer 3 which, moving from left to right (arrow B), locks the lug 14 of the indicator 16, and thus keep it in the "visible" position.
  • the core 8 then returns to its initial position as soon as the circuit breaker is open (not visible, which is made possible by the fact that the indicator 5 can move in rotation with respect to the core 8 in this case. meaning).
  • the return spring 6 pushes the drawer 3 in the rear position and unlocks the indicator 16.
  • the spring 12 then reminds the indicator 16 in its hidden position.
  • the device is then in the working position and able to fulfill its role.
  • the window 13 also has the function of protecting the internal mechanisms against external penetrations of foreign bodies.
  • the technical advantages seen by the user are as follows:
  • the signal lamp operates independently of the power source of the electrical installation that the circuit breaker protects: it is mechanical. This results in better security for the user. Indeed, the separation of the upstream and downstream circuits is guaranteed in all circumstances; the information of a differential defect is reliable whatever the state of the source; the isolation of the user is guaranteed and the information is in any case kept in memory.
  • the erasure of the signaling is achieved by simply closing the circuit breaker by the user (some devices require action in two maneuvers).
  • the intrinsic technical advantages of the invention are the following:
  • the stress on the differential trip relay is low and thus does not reduce the reliability of the protection. Indeed, the driving force of the signaling means is low and the operating friction is reduced.
  • the reset of the differential and reset functions of the circuit breaker are independent of the initialization of the signaling. Indeed, the functional mechanical connections between the differential function, the tripping device of the circuit breaker and the signaling function of a differential fault are realized in such a way that their initializations are independent.
  • the presence of the transparent material window makes it possible to protect the device against external interventions. Indeed, it does not allow dust and other pollution to enter the device and external intervention on the operation of the indicator and therefore the trip relay is not possible.
  • a device makes it possible, in fact, to maintain the indicator spring in a stable position during assembly and a second allows the automatic implementation in the operative position of this spring when installing the cover of the differential function.
  • Another device makes it possible to maintain the spring of the drawer during its installation in the apparatus.
  • the signaling means is self-amarmable, thanks to the spring of the electromagnet in the case of the first embodiment, or thanks to the spring associated with the indicator for the second embodiment.
  • the invention can be applied to any breaking device with own current, auxiliary source or other requiring a signaling means of any electrical fault.
  • the device of the invention is particularly suitable when the electromagnet used is of the type with a plunging core and therefore with a fugitive action, it would also be possible to apply the concept stated in claims 1 and 2 to a switchgear using a magnetic latching type relay.
