Definitions
- the present invention relates to an electrical apparatus for protecting at least one circuit breaker-type current line, the design of which makes it possible to distinguish a breaking block at which the opening of the contacts takes place and the extinction of the electric arc generated on this occasion, and a trigger block comprising at least one actuator capable of causing the cut.
- the invention relates more particularly to the breaking block, which is more precisely and essentially constituted - for each line to be protected - a movable contact between two stable positions, respectively in support and at a distance from a fixed contact, and a control lever of the position of the movable contact connected thereto by means of a mechanical lock able to switch between two stable positions corresponding to the opening and closing of the contacts following a manual action on the remote.
- This lock can also switch to an open position of the contacts following a mechanical action of a trigger echoing an electrical fault on a line.
- the trigger block which comprises for this purpose at least one actuator of the magnetic type, or thermal, or electronic, which actuates the trigger for the tilting of the lock.
- the present invention actually pursues the logic of modularity initiated by the separation of the breaking and tripping blocks, but this time at the breaking block itself.
- the breaking block is modular and consists of distinct subsets:
- the breaking block will consist of a breaking subassembly, a trigger and three arc extinction subsystems. Each of them is in fact constituted of a coherent material entity, assembled to the others by simple implementation of a simple mechanical connection.
- the breaking subassembly comprises a movable contact bar (s) (s) connected to the mechanical lock and rotatably mounted in a module having as many breaking chambers as lines to protect and consists of a support and a lid fixed to each other, incorporating the side walls as tight as possible delimiting each breaking chamber, the bar comprising a movable contact per chamber.
- the cut-off subassembly organizes the hermeticity between the different breaking chambers.
- the different movable contacts, if any, are mounted on the same contact bar) and all the lines are therefore open by tilting the lock when there is a problem on at least one of said lines or following a voluntary opening action on the joystick.
- the housing of the electrical apparatus further comprises a number of fixed contacts equal to the number of movable contacts arranged so that the opening of the moving contacts in case of a problem is facilitated.
- the side walls delimiting each breaking chamber comprise metal plates.
- side shielding located on each side and at the contact area between each pair of movable contact / fixed contact, in the form of separate plates or U with a base and two lateral shielding plates which constitute the jambs, can possibly associate side plates further reinforcing the shielding.
- the fixed contact can be placed, between said side shielding plates, at the origin of an arc horn inserted between two arrival branches of a conductive sheet integral with a connection terminal, and which participates in the evacuation of the arc to the deionization stacks.
- These shielding plates actually make it possible conventionally to promote the movement of the electric arc caused when opening the contacts in short circuit. They have the effect of pushing, because of the electromagnetic field created, the electric arc to the plates or deionization plates, and they also increase the electrodynamic repulsion of the movable contacts in case of short circuit.
- the side walls of the interrupting chambers are in practice provided with housings for the shielding plates, of which there are one or two in each side wall. Depending on the case, and in particular according to the expected performance of the product during manufacture, these shielding plates may not be installed.

- the mechanical lock to which is connected the control lever, is articulated to said shaft.
- the arc extinction subassembly comprises a stack of deionization plates inserted in an insulating shell having an opening that projects against an end opening of corresponding dimensions of a breaking chamber in a the side of said proximal chamber of the contact zone between the movable and fixed contacts, the respective walls of the cutting chamber and the shell delimiting their respective openings facing each other being fastened in a sealed manner.
- Each arc extinguishing subsystem therefore attaches in the extension of an interrupting chamber, so that the electric arc can be blown from said chamber to the deionization plate stack of the sub-assembly. arc extinction which is fixed to it.
- each cutting chamber has a raised edge delimiting the end opening, adapted to engage with the rim of the opening of the shell.
- the mounting of the arc extinguishing subassembly on the subassembly of cut is thus simplified by adaptability of the shapes surrounding the openings allowing the passage of the electric arc from one to the other, in order to allow a simple mechanical interlocking.
- one of the deionization plates may also be used for fixing the shell to the interrupting chamber, and for this purpose protrudes beyond the opening of the shell in order to fit in. a groove formed in the raised flange surrounding the end opening of the interrupting chamber.
- said fixing plate is that which is at the end of the stack opposite to the contact zone.
- the shell In order to manage the evacuation of the cutoff gases, the shell also has a gas exhaust opening opening opposite the opening to the cutoff chamber at the level and in front of the wafer. fixation.
- arc extinction subsets are constructed as unipolar elements, added to the pole-to-pole breaking subsets.
- the shell of the shell has two flat lateral faces allowing them to be contiguous.
- the entire clipping block is a coherent block that can be handled as such, in particular for assembly purposes in a housing of an electrical appliance.
