- the same mechanism ensures the maintenance of closed contacts, involving a high mechanical load and communication with peripheral accessories, involving a low mechanical load.
- the passage of a large mechanical flow in the sensitive communication components disturbs the input and output information, and therefore the general operation of the device.
- the management of the energy of the switch contacts by a single mechanism does not allow to have auxiliaries common with the circuit breakers.
- the pressures of all the contacts in particular in the case of differential switches with high service current lead to mechanical systems incompatible with the auxiliaries.
- This problem is currently solved by specific auxiliaries communicating with standard auxiliaries.
- the present invention solves these problems and proposes a device for controlling an electrical apparatus making it possible to have auxiliaries common to the circuit breakers, with which the communication elements are not subjected to a high mechanical load.
- the subject of the present invention is a device for controlling an electrical appliance of the kind mentioned above, this device being characterized in that it comprises a first mechanism, referred to as power, ensuring the opening and manual closing contacts and maintaining the contacts in the closed position, and a second mechanism, said control and signaling, said second mechanism being able to control the automatic opening of the contacts and to communicate with the aforementioned peripheral accessories.
- the aforementioned peripheral accessories comprise at least one triggering aid and / or a device for signaling the state of the contacts of the device.
- the two mechanisms are kinematically linked in such a way that, when the contacts are closed by the operator or a remote control, the two mechanisms are operated simultaneously by the joystick, so as to transmit the information on the open or closed state of the device to the signaling auxiliaries.
- the two mechanisms are kinematically linked such that the automatic opening of the contacts by triggering the control and signaling mechanism is achieved by keeping the handle in the closed position.

- - Figure la is a partial view in section, illustrating a part of the control mechanism and a triggering auxiliary
- FIG. 2 is a partial view of the preceding figure, illustrating the mechanism of a switch according to the invention, seen from the front, in the closed position of the contacts
- FIG. 3 is a view similar to the previous one, illustrating the mechanism of the switch, seen from the rear, in the closed position of the contacts
- FIG. 4 is a side view of a differential switch according to the invention, similar to FIG. 1, in an open position of the co ntacts.
- a differential switch I is shown intended to be connected to the electrical conductors of an alternating network by means of a connection terminal in order to protect the network when a differential defect occurs.
- This apparatus 1 is housed in a narrow housing consisting of two parts, one of which has been removed to reveal the internal mechanism of the switch I.
- this switch I comprises two contacts 1, 2 respectively fixed and mobile.
- This movable contact 2 is carried by a contact support 3 rotatably mounted between a closed position of the contacts and a position separated from the contacts 1, 2.
- This switch I comprises two distinct mechanisms 4,5, respectively a so-called power mechanism 4 and a so-called control and signaling mechanism 5.
- the power mechanism 4 is intended to ensure the opening and closing of the contacts manually 1,2 through the handle 6, and maintaining the contacts 1,2 in the closed position.
- the control and signaling mechanism 5 is intended to control the automatic opening of the contacts 1,2 in the event of an electrical fault for the safety of the persons, by the action of a differential protection device, and to communicate with peripheral accessories 8.
- These accessories 8 include signaling auxiliaries and triggering auxiliaries.
- the signaling auxiliaries are intended to indicate the state of the contacts 1, 2 of the switch I, which can be closed, opened following a manual opening, or opened following opening on a fault.
- the triggering auxiliaries make it possible to open contacts 1,2 of switch I independently of the trigger of switch I, as will be explained in more detail later.
- the first mechanism 4 comprises a toggle joint 9 formed by two links 10,1 1 hinged relative to one another, one of the rods 10 being hingedly connected to the lever 6, while the other 11 is connected in an articulated manner to the support 3 of the movable contact 2, the assembly constituting a breakable mechanical connection.
- This toggle lever 9 is maintained in a state corresponding to a closed state of the contacts 1, 2 by an attachment system 12.
- the second mechanism 5 comprises a rotary bar 13 adapted to be driven by a means trigger 14 and release a rotating plate 15, which plate 15 is intended to cooperate with the aforementioned attachment system 12 in a manner that will be explained later.
- This triggering means 14 is an electromagnetic relay 16 actuated by a fault detection means (not shown).
- the turntable 15 is hingedly connected to the handle 6.
- This plate 15 also has a portion 15a adapted to cooperate with the signaling auxiliaries, and the bar 13 has a portion 13a adapted to cooperate with the triggering auxiliaries.
- the trigger activates the relay 16.
- the pin 16a of the relay 16 then drives a reset blade 17.
- the blade 17 then drives the bar 13, which unlocks the hooking between the bar 13 and the piece 7 releasing the plate 15.
- the plate 15 then actuates the attachment system 12 which unlocks the toggle 9, which causes the opening of the contacts 1, 2.
- the part 15a of the plate 15 communicates with the signaling auxiliaries, so that it indicates a state triggered on a fault. Note that the kinematics of the assembly allows the opening of the contacts 1,2 by triggering the mechanism 5, the lever 6 remaining in the closed position (free trigger).
- a needle 18 of the auxiliary triggers the mechanism 5 by driving the bar 13, which bar 13 unlocks the hooking between the piece 7 and the bar 13 releasing the plate 15 which acts on the attachment system 12.
- the needle 18 of the auxiliary cooperates with the portion 13a of the bar 13.
- the control mechanism has a kinematics adapted to auxiliaries common circuit breakers.
- the position of the control and signaling axes to the auxiliaries is independent of the position of the power mechanism. It is then possible to align the control and signaling axes with those of the auxiliaries which are common to other control and / or electrical protection and / or electrical distribution devices.
- the device according to the invention makes it possible to transmit the open or closed states of the switch on the same axis as the control axes. This device also makes it possible to eliminate the constraints related to the high loads of the closing and opening mechanism of contacts, induced on the control and signaling mechanism.
- the adaptability to the auxiliaries is then industrially attainable. Which was not possible with the monobloc design.
- Another advantage is that it is possible to use the same control mechanism and signaling that those differential blocks associated with circuit breakers.
- the relay works in an environment of identical static and dynamic loads.
- This same relay was previously subjected to stronger constraints in a differential switch than in a differential block, which required the realization rather difficult of a relay capable of operating with two different systems.
- the invention therefore allows the realization of a differential switch using a common mechanical subassembly with differential blocks associated with circuit breakers.
- the same differential relay is used for a differential switch and for a differential block.
- the communication devices are not subjected to a high mechanical load associated with the 125A caliber, hence compliance with the adaptability with auxiliaries.
- the invention applies to any apparatus comprising a fixed contact and a movable contact, said movable contact being operable either manually or automatically, and a mechanism for opening and closing manually, automatic opening and maintaining contacts in the closed position, said mechanism communicating with peripheral accessories.
- the invention therefore advantageously applies to switches, circuit breakers, contactors and any electrical distribution, control, protection, etc .. having the aforementioned characteristics.
- the invention is not limited to the embodiments described and illustrated which have been given by way of example. On the contrary, the invention comprises all the technical equivalents of the means described and their combinations if they are carried out according to its spirit.
