Definitions

  • the present invention relates to a disconnecting device that can be associated with a circuit breaker to add a disconnecting function to the latter.
  • the user may wish that the extractable part of such a disconnecting device can optionally be completely removed or only partially separated in order to avoid losing this part.
  • the invention therefore aims to avoid taking the extractable part.
  • Another object of the invention is to simplify the production of such an apparatus and its mounting on the circuit breaker without neglecting the usual safety devices aimed at avoiding load disconnection and untimely re-establishment of severed links.
  • the invention relates to a disconnecting device associable with a circuit breaker having a housing provided with an operating button which is capable of assuming a closed position and an open position
  • the disconnecting device comprising a main element which can be added to the circuit breaker housing and which comprises first contact parts connectable to terminals of the circuit breaker, an extractable contact-carrying part removably attached to the main element and carrying second contact parts which cooperate with the first contact parts in the closed position and which are separated from the first parts in the open position of the disconnecting device, according to the invention characterized in that the contact-carrying part extractable from the main element has at least one stop element for be retained with respect to the main element in an intermediate position so as to guarantee a sectioning both in the extracted position and in the intermediate position, and the stop element belonging to the extractable part is a hooking or snap-fastening element on the main element and is elastically erasable by the operator.
  • the user can thus at will either completely extract the removable part from the main element, preferably made in the form of a drawer, or only partially separate the removable part from the main element to avoid the loss of this part, and it can in either case attach to the main element a locking device.
  • the coming of the removable part in the intermediate position can advantageously be helped by springs and the deletion of the hooking or latching element can be carried out using side levers.
  • the main element may have a tongue for guiding the removable part and, in this tongue, at least one locking opening capable of coinciding with an opening of the removable part in order to immobilize the latter.
  • the circuit breaker housing may have bearings at the upper rear part of its side walls which cooperate with pivots of the main element to allow it to be pivotally mounted and held when traction is exerted on the removable part.
  • the multipole circuit breaker 10 illustrated diagrammatically in the figures is a low voltage electromechanical circuit breaker, the housing 11 of which carries on its front face 11a a button 12 mounted so as to pivot perpendicularly to this face.
  • the button can take an open position or stop position ( Figures 1 and 2) and a closed position or on position ( Figure 3) and it includes a notch 13a aligned with a recess 13b of the housing in the stop position, for a purpose which will be explained later.
  • the circuit breaker has for each pole an upstream terminal 14 and a downstream terminal 15 and, between them, an interruptible electrical connection with separable contacts not shown.
  • the establishment of the connection is caused in particular by putting the button 12 in the on position, while the interruption of the connection is caused in particular by the action of a lock which is acted upon by magnetothermal triggers or by the setting of the button in stop position.
  • the rear part of the case 11 of the circuit breaker is attached to a support such as a standardized profile 16.
  • a disconnecting device 20 which can be fixed in the manner of an additive to the casing 11 of the circuit breaker.
  • the disconnecting device has for each pole a sectionable current path which ends, on the one hand, by pins 21 insertable in appropriate housings 14a of the upstream terminals 14, on the other hand, by screw terminals 22 intended for the upstream wiring.
  • the apparatus 20 comprises a main element 23 which remains permanently on the circuit breaker.
  • the element 23 is provided with contacts 24 with elastic displacement, respectively connected to the pins 21 and to the terminals 22.
  • the device 20 comprises a removable sectioning part 25 provided with contacts 26 in the form of rigid blades insertable between the contacts 24.
  • the fixed element 23 comprises at the rear, that is to say on the side of the support 16, pivots 27 situated at the lower end of the cheeks 28 to cooperate with these bearings 17 of the housing 11.
  • the bearings 17 are provided in the form of recesses in the side faces of the housing 11, at the upper rear part thereof, to allow the device to pivotally mount and prevent it from being torn off from the housing 11 when pull on the contact-holding part 25.
  • the removable contact-holder part 25 comprises a body 30 provided at the front with a pull-out 31 provided with lateral projections 32 defining between them a recess 32a and a central opening 33 of sufficient width to accommodate three padlocks A, B, C side by side ( Figure 9).
  • the body 30 comprises a finger or a heel 34 adapted to the notch 13a of the button and to the recess 13b of the housing in order to be able to slide forward when the button is in the open position (stop ); the heel 34 is locked in the notch 13b by the rear face of the button when the latter is in the closed position (on).
  • the removable contact piece 25 comprises openings 35 which allow the passage of a screwdriver to access the terminals 14, 22 of the main element.
  • Two thrust elements 36 are also provided in the part 25 to cooperate with compression springs 37 housed in the fixed main element 23.
  • the pull tab 31 is equipped with two lateral levers 38 each composed towards the rear of a detent or hook arm 39 and towards the front of a pressure range arm 40 situated at the level of the lateral projections 32.
  • the arms 38 can pivot elastically around vertical axes 41 when a pressure on the pads 40.
  • Each notch or hook 39 can slide in a recess 42 and hook against a stop 43 of the fixed element 23 in an intermediate position of the part 25 which provides a required cutting distance D (FIG. 6 ).
  • the fixed main element 23 comprises projecting forwards a tongue 44 split in the middle so as to let pass a central contact blade 26 and having slides 45 for the sliding of the part 25 and an opening 46 suitable for housing three padlocks A, B, C or other locking devices ( Figure 10).
  • the part 25 has a central recess 47 for engaging and sliding on the tongue 44.
  • the element 23 comprises a front wall 48 which is positioned in front of the housing 11 while having openings 49 for access to the terminals 14 of the circuit breaker.
  • the part 25 comprises a pin 50 intended to engage perpendicularly to the front wall 48 of the element 23 in an opening 51 of the latter and in a recess 52 in the housing 11 of the circuit breaker.
  • pin 50 abuts on the upper face of the circuit breaker box and prevents mounting. It is thus ensured that the heel 34 comes to feel the position of the button 12.
  • the obligation to engage the pin 50 in the recess 52 ensures that the pivoting of the disconnector is complete and that the closing of the disconnector cannot have place only after detection of the circuit-breaker stop position.
  • the disconnecting device which has just been described is used in the following manner.
  • the operator pulls the part 25 in the intermediate position and engages the pivots 27 in the respective bearings 17 on the side faces of the circuit-breaker case from the rear (figure 11), then fold the device to engage the pins 21 in the openings 14a of the terminals 14 (FIG. 12), and finally push the part 25 in the closed position (FIG. 5) and tighten the screws of the terminals by means of a screwdriver that it passes through the openings 35 of the part 25 and 14b of the main element 23 of the additive.
  • the heel 34 of the additive is then housed in the recess 13b of the housing 11, behind the button 12, so that the operator can at will switch the circuit breaker on and off (FIG. 5).
  • the removable contact-holding part 25 is immobilized relative to the element 23 by the force for retaining the contact parts 26 and possibly by snap-fastening or hard point elements.
  • the part 25 can be locked in this position, because the end of the tongue 44 projects into the recess 32a and makes it possible to introduce padlocks in this recess and in the opening 46 (FIG. 8).
  • the contact piece 25 is lockable in the intermediate sectioning position because its opening central 33 then coincides with the opening 46 of the fixed tongue 44 and at least one locking piece, for example one or more padlocks, can be passed through these openings (FIG. 9).
  • the heel 34 remains engaged in the notch 13a and thus prevents restarting the circuit breaker.
