Definitions
- the present invention relates to a common structure for producing n-phase and neutral protection blocks, composed of a differential stage provided with a mechanical release for the opening of the neutral and n circuit breakers protecting separate circuits for each phase.
- the idea underlying the invention is to group together on the one hand different electrical functions in a compact one-piece assembly, and on the other hand to constitute a common industrial platform for different similar products, mainly in view to reduce costs in manufacturing.
- the multifunctional base identical to all these variants led, in the context of this invention, to develop what has been described as a common platform with a view to simplifying the industrialization phase by creating a structure designed to include all the elements and characteristics common to the various blocks envisaged, and which allows their final differentiation by resorting to only a minimum number of operations and stri nelies.
- tegration of de d icities and characteristics in the same structure also makes it possible to increase compactness of the blocks in that the multifunction aspect is automatically integrated into the design of common platforms.
- the common structure of the invention comprising (n + 1) input connection devices connected to the differential stage and (n + 1) output connection devices, each circuit breaker having its own tripping mechanism magnétothermique, namely a mechanical trigger lock associated with a magnetic actuator and a thermal actuator, connecting members being provided for connecting the mechanical trigger of the differential stage and the locks of the circuit breakers, each connecting member connecting the trigger and at least one lock of an adjacent circuit breaker, ie the locks of two adjacent circuit-breakers, characterized in that it can be converted into three different protection blocks:
- the connecting elements between the mechanical trigger of the differential stage and the locks of the circuit breakers being connected in order to cause the simultaneous tripping of the n circuit breakers when tripping a circuit breaker or the trip unit the differential stage;
- n-phase and neutral protection block whose tripping mechanisms operate independently on each phase, the connecting members being provided solely for transmitting to the locks of the circuit breakers the triggering of the mechanical trigger of the differential stage;
- phase-neutral protection block a common polarity setting element for the inputs of the n circuit breakers at the potential of the single phase being added to the n-phase and neutral protection block at the output of the differential stage or at the differential circuit-breaker at n phases and neutral.
- the trigger can be simultaneous for all products regardless of the origin of the trigger.
- simultaneous tripping can occur only when the failover of the circuit breaker locks is controlled by the movement of the trigger of the differential stage, regardless of the positions of the locks of the circuit breakers.
- the mechanical trigger of the differential stage is relay, and it is therefore the movement of the relay pallet which actuates the locks of the circuit breakers via an appropriate mechanical connection.
- an additional component is preferably provided for securing the handles of the circuit breakers.
- connection member of the n-phase and neutral protection block is a lever or a cam, one of whose ends or surface is displaced, when the mechanical trigger of the differential stage is triggered, along a path allowing it to come into contact with the lock of each circuit breaker in order to unlock it, each lever or cam having means for securing it to at least one identical lever or cam adjacent to it, and connecting means for securing to mechanical trigger of the differential stage allowing the latter to pass a movement when it triggers.
- This lever or this cam are separate from the release or the locks themselves, and comprise a mechanical connection only with the relay relay of the differential stage and / or a lever or a homologous cam, or with two levers or two identical cams of circuit breakers contiguous on both sides.
- the lever or the cam is located at a location that makes it or the product from the common structure insensitive to the position of the locks of the circuit breakers or on the contrary depends on the movement of a lock (in the case of the GFCI).
- Each lever or moving cam therefore comprises securing means to at least one lever or at least one identical cam of an adjacent circuit breaker and means of the ground / ground idarization to the mechanical trigger of the differential stage which are preferably identical. To ensure the simultaneity of the disjunctions during the tripping of the differential stage, it is necessary that these means ensure the connection between all the levers or cams and said relay.
- said levers are rotatable, articulated at one of their ends in the vicinity of the control lever of the circuit breaker, the other end having a contact zone with the lock of the circuit breaker.
- n 3 and the supply of blocks is in three-phase and neutral.
- each product comprises a differential stage (1) located upstream of a row of circuit breakers (2), whose particular function is to cut the downstream circuits by opening the contacts of the circuit breakers via a circuit breaker.
- classical toroidal pattern and trigger relay is generally located at one of the lateral ends of the block, and a number of circuit breakers (2) are arranged in the direction of the other end of said block.
- n 3 and the circuit breakers (2) are therefore three in number.
- the functions provided are integrated in a one-piece assembly consisting of a single housing (3).
- This housing (3) incorporates a differential protection assembly (1) consisting of a measurement toroid connected to a relay, which is capable, via a mechanical link, of triggering the locks of the associated circuit breakers (2) if a differential fault occurs.
- the mechanical connecting member (4) does not prevent the individualized management of the circuit breakers (2). It thus ensures the simultaneous release of the locks of the circuit breakers (2) when the differential stage (1) triggers, but a circuit breaker (2) whose lock toggles has no effect on the adjacent circuit breakers (2). This is not the case for the product (B), for which the connecting member is replaced, relative to that of the product (A), by a member (5) providing a mechanical connection causing the triggering of the entire protection block lines (B) regardless of the line on which the problem causing the trip occurs.
- the modification of the connecting member is the only adaptation to be made on the platform or common structure to pass from the product (A), in this case a three-phase protection block-neutral product (B) which represents a three-phase differential circuit breaker and conventional neutral.
- the passage to the product (C) is carried out no less simply from the product (A) or (B), simply by adding a member (7) for setting in common polarity of the inputs of the n breakers to the potential of the single phase at the output of the differential stage.
- the link member (6) is then either the mechanical connection member (4) of the n-phase and neutral protection block, or the mechanical connection member (5) of the n-phase and neutral differential circuit breaker.
- the common structure can be rapidly, and with at least one very simple change, transformed into one of the three products (A, B, C) described above. .
- the economic advantage of the invention is real and interesting.
