Definitions

  • the present invention relates to the technical field of equipment for distributing and controlling electric power and particularly relates to a residual current device that can be associated with an electric circuit-breaker.
  • residual current devices are a type of electric equipment comprising a totalizer transformer and a trip device that is electrically connected to the secondary of said transformer in order to mechanically causing an associable circuit-breaker to open in the event that the residual current device has triggered.
  • the object of the present invention is to provide a residual current device that can be assembled to an associable electric circuit-breaker in a particularly comfortable and quick manner.
  • a residual current device that can be associated with an electric circuit-breaker 1 has been generally designated with 2.
  • the circuit-breaker 1 is a multipole circuit-breaker that can be fixed to a DIN rail and is, in the example reported herein, in a non-limiting manner, a magneto-thermal quadrupole circuit-breaker, such as formed by juxtaposing four DIN unipolar modules.
  • the four DIN unipolar modules have kinematic actuators that are interconnected by mechanical coupling members.
  • the circuit-breaker 1 has an approximatively parallelepiped-shaped body. From a front face 3 of the circuit-breaker body 1, a pivoting drive lever 4 protrudes, which is provided to operate the circuit-breaker 1.
  • the drive lever 4 is embodied by a C-shaped section bar engaging the four drive levers of the DIN unipolar modules, such as to allow simultaneously operating these levers.
  • the circuit-breaker 1 comprises two counter-posed arrays of electric connection terminals for electrically connecting the circuit-breaker 1 to the line electric circuit, i.e. the electric circuit upstream of the circuit-breaker, and to the load electric circuit, i.e. the electric circuit downstream of the circuit-breaker.
  • each of these connection terminals comprises a clamp.
  • Fig. 2 in the body of circuit-breaker 1 there are provided, in a known manner, on the upper 5 and lower 6 faces, corresponding series of openings 7 for access to the clamps, of which only the access openings 7 on the lower face 6 are shown in Fig. 2 .
  • the clamps can be tightened by means of screws that can be accessed from front openings 8, 9 that are provided on the front face 3 of the body of circuit-breaker 1.
  • some slots 10 are provided (only those provided on the lower face are shown in Fig. 2 ), which are such, by extending within the circuit-breaker body, as to be capable of receiving some blocking tabs therein, which prevent access to the screws tightening the clamps by closing the openings 8, 9.
  • an access slot to the inner kinematic mechanism of circuit-breaker 1 is provided, which is suitable to be passed through by the release pin 15 of the residual current device 2.
  • the slot 13 provided on the side face 11 is shown.
  • An entirely similar slot is provided in the same position on the side face 12, even if it is not shown in the drawings.
  • the residual current device 2 comprises:
  • the residual current device 2 comprises a first part 20, 21 and a second part 24 that are pivotally hinged to each other and carrying the interconnection electric terminals 22, and the mechanical coupling means 15, 16, respectively.
  • the mechanical coupling means 15, 16 comprise the release pin 15 and preferably the key pins 16.
  • the release pin 15 projects from a slot 18 of the wall 19a to be inserted within a respective slot provided in the side wall 12 of the circuit-breaker thus ensuring the opening of the circuit-breaker 1 by the action of the residual current device.
  • the residual current device 2 comprises a receptacle 20, 21 that is approximatively L-shaped, and has:
  • the residual current device 2 further comprises a mechanical connection member 24 that is pivotally connected to the second receptacle branch 21 and carries the mechanical coupling means 15, 16 to mechanically connect the residual current device 2 to the circuit-breaker 1.
  • the mechanical connection member 24 has an essentially box-like shaped main body which has a corner that is hinged to a corner of the second receptacle branch 21 by means of a pin 26, which acts as the axis of rotation.
  • the corner of the mechanical connection member 24 that is hinged to the second receptacle branch 21 is a corner distal to the first receptacle branch 20 and proximal to the associable circuit-breaker 1.
  • the first receptacle branch 20 has an upper face 23 that is intended to be juxtaposed to the lower face 6 of the body of the associable circuit-breaker 1. From the upper face 23 the interconnection electric terminals 22 are provided, in a number of four in the example, each of which is preferably made in the form of a conductive bar (for example, of copper) which is intended to be received through the access openings 7 in a respective clamp of the circuit-breaker 1.
  • the first branch 20 further includes selection means, which are suitable to prevent the coupling between the residual current device 2 and a circuit-breaker that does not have a proper number of poles to be coupled to this device 2.
  • the selection means are embodied by tabs 25 provided on the face 23 of the first receptacle branch 20 to be capable of being received in respective seats that are opened on the lower face 6 of the circuit-breaker 1.
  • the tabs 25 and respective seats operate as keys to allow the coupling between a differential device 2 with a determined number of poles to circuit-breakers 1 having the same number of poles.
  • the electric terminals 22 are end portions of rigid conductors that run within the first receptacle branch 20 to the inside of the second receptacle branch 21 where a toroidal totalizer transformer (not shown in the drawings) that is run through by these conductors carries out the differential measurement.
  • a toroidal totalizer transformer (not shown in the drawings) that is run through by these conductors carries out the differential measurement.
  • the mechanical connection member 24 houses a trip device therein, for example a relay, which is operatively connected to the release pin 15 and electrically connected to the secondary of the totalizer transformer.
  • the electric connection for example can be carried out by means of flexible and loose conductors such as to be capable of allowing the rotation of the member 24 relative to the second branch 21.
  • the mechanical connection member 24 houses therein a mechanism for manually driving the trip device, not shown in the drawings, and that can be operated by means of a lever 27.
  • the lever 27 has a projection 28 extending to the associable circuit-breaker 1 suitable to co-operate with the drive lever 4 of the circuit-breaker 1, such that when the residual current device 2 and the circuit-breaker 1 are mechanically and electrically coupled to each other, a movement of the drive lever 4 for closing the circuit-breaker 1 automatically causes the reset of the trip device of the residual current device 2.
  • the mechanical connection member 24 can be either shaped like a shell having a mouth facing the second receptacle branch 21 or like a substantially closed receptacle provided with an access opening facing the second branch 21 of the receptacle and provided for flexible conductors to pass therethrough for connection to the secondary of the totalizer transformer.
  • the residual current device 2 further comprises hooking means for locking the circuit-breaker 1 and the residual current device 2 in the configuration in which the two elements 1, 2 are electrically and mechanically coupled to each other, such that they form a compact magneto-thermal-differential circuit-breaker unit.
  • these hooking means include a hooking element 30 in the form of a bar that is slidably received within a suitable seat provided within the mechanical connection member 24.
  • the bar 30 is preferably inclined relative to the side face 12 of the circuit-breaker 1 and is slidable relative to the circuit-breaker 1 between:
  • the bar 30 has an end portion 32 that is provided with gripping means, such as, for example a notch 29, through which the bar can be brought, for example by means of a tool with a blade-like end, from the forward operative position to the backward operative position.
  • gripping means 19 can be foldaway-received within the seat of the bar 30 when the bar 30 is in the hooked position. Thereby, after the bar 30 has been brought to the hooked position, the bar cannot be extracted, such as to make substantially impossible to remove the circuit-breaker 1 from the residual current device 2.
  • an end portion of the seat of the bar 30 within the member 24 has a wall portion 33 that is pre-fractured and removable. By removing this wall portion 33, the gripping means 29 of the bar 30 can be accessed when the latter is in the hooked position, and thus release the circuit-breaker 1 from the residual current device 2. It should be observed that, however, this removal is such as to leave a clear and irreversible evidence, in accordance with what is provided by the safety regulations in force.
  • the residual current device 2 includes locking means that are suitable to hold the mechanical connection member 24 in the angular position in which this is such as to be capable of establishing a mechanical coupling with the circuit-breaker 1, by preventing a rotation of this member after the latter has moved to the angular position of mechanical coupling with the circuit-breaker 1.
  • the side wall 19a of the second branch 21 and the side wall 19b of the member 24 are substantially aligned with each other to form an individual wall 19a, 19b suitable to be juxtaposed to the side wall 12 of the circuit-breaker 1.
  • the locking means shown in Fig. 3
  • the locking means comprise:
  • the conjugated locking means 36 comprise a channel 36, which is depicted with a dotted line in Fig. 3 , having an opened end portion 35 defining a retaining seat for the tooth 34 in the locking position and having an opposite opened end portion suitable to receive a pointed tool to disengage the tooth 34 from the retaining seat thereof.
  • the residual current device 2 further includes interconnection electric terminals, or output terminals, to connect the residual current device 2 to a load circuit, i.e. to an electric circuit downstream of the residual current device 2, such as for example a domestic electric network.
  • these output electric terminals are in the shaped of clamps.
  • an array of access openings 40 to the clamps is provided, in a known manner, in the second receptacle branch 21.
  • the clamps can be tightened by means of screws that are accessible through front openings 41 provided on the second receptacle branch 21.
  • the residual current device 2 comprises safety means suitable to at least partially prevent an access to the screws of the clamps of the output terminal of the residual current device 2 when the pivoting member 24 is oriented such as to move to an angular position other than the mechanical connection position.
  • these means include a sliding plate 42 housed within the second receptacle branch 21 and provided with an array of openings (two of which have been shown with a dotted line in Fig. 3 by way of example, and designated with numeral 44).
  • the sliding plate 42 is preferably operatively coupled to the connection member 24, for example by means of a bracket 45, such that:
  • the residual current device 2 further includes a sliding screen 46 that can be coupled to the first receptacle branch 20 and including a comb of blocking tabs 47.
  • the screen 46 is at least partially receivable within a suitable seat provided in the first branch 20 and is slidable relative to the latter between an extracted position and a forward position. In the latter position, each blocking tab is inserted within a respective slot 10 (shown in Fig. 2 ) of the circuit-breaker 1 to prevent access through the front openings 9 to the screws of the clamps that are intended to be connected to the interconnection terminals 22 of the residual current device 2.
  • anti-tampering signalling means are further provided, in order to prevent the sliding screen 46 from being extracted by unauthorized operators after it has been inserted.
  • These means comprise, for example, a pair of holes 48, 49 which are provided within the first branch 20 and sliding screen 46, respectively, which are suitable to receive, in the forward position of the sliding screen 46, a wire seal.
  • a subsequent operation provides that the bar 30 is moved, which can be obtained by applying a pressure on the latter in the direction and way of the arrow VII until the locking position has been reached, in which the end portion of the bar 30 opposite the end portion 32 is engaged with the conjugated retaining means that are provided on the side face 12 of the circuit-breaker 1. Furthermore, with further reference to Fig. 5 , a subsequent operation provides for tightening the screws of the circuit-breaker 1 which can be accessed via the openings 9, in order to make the electrical connection stable between the circuit-breaker 1 and the residual current device 2.
  • a first variant embodiment of residual current device 2 is shown, which essentially differs from the residual current device described above, in that it is provided with different locking means 54, 55 to hold the mechanical connection member 24 in the angular position of mechanical connection.
  • these locking means comprise a key 55 that is provided on the second branch 21, held in the forward position by a spring (not shown) and such as to be pushed to counter-act the action of this spring, and a shaped tab 54 projecting from the connection member 24.
  • the shaped tab 54 is provided with a first cavity C1 that is shaped such as to be engaged with the key 55 when the latter is in the forward position thereof in order to hold the connection member 24 in the angular position of mechanical connection.
  • the key 55 is shaped such that (for example, it has a notch or a discharge) it does not interfere with the shaped tab 54 when it is pressed in the forward position. Thereby, the connection member 24 can be unlocked from the angular position of mechanical connection.
  • the projecting tab 54 further has a second cavity C2 that is shaped such as to be engaged with the key 55 when the latter is in the forward position thereof in order to hold the connection member 24 in an angular position different from the position of mechanical connection and such that the mechanical coupling means 15, 16 of this member are substantially noninterfering with the face 12 of the circuit-breaker during a movement of the circuit-breaker 1 towards the device 2 in order to provide the electrical interconnection between the circuit-breaker 1 and the residual current device 2.
  • the projecting tab 54 is further provided with a thrust element 56 which is suitable to co-operate with the sliding plate 42 ( Fig. 7 ) to cause the sliding of the latter during the rotation of the connection member 24.
  • the residual current device 200 is different from the residual current device 2 described above essentially in that the second receptacle branch 221 is made as an individual block and has a corner that is pivotally connected to, for example hinged about the axis 226, an end portion of the first receptacle branch 220.
  • the residual current device 200 also advantageously comprises a first part, i.e. the branch 220, and a second part, i.e. the branch 221, that are pivotally connected (for example pivoted) to each other, and carrying the interconnection electric terminals 22 and the mechanical coupling means 15, 16, respectively.
  • flexible electrical connection means can be provided, for example in the form of conductive plaits, at least proximate to the axis of rotation 226.
  • the residual current device 220 can be also provided locking means in the form of a sliding bar 30 and screen means 46 in the form of a sliding screen comprising a comb of blocking tabs 47.
  • locking means in the form of a sliding bar 30 and screen means 46 in the form of a sliding screen comprising a comb of blocking tabs 47.
  • a pre-fractured wall portion can be provided, which is suitable to make the gripping means of the bar 30 accessible after the latter has been inserted within the seat thereof.
  • the circuit-breaker 1 To assemble the kit of parts in Fig. 9 , the circuit-breaker 1 must be moved towards the residual current device 200 as indicated by the arrow IX, thereby establishing an electric connection between both pieces of equipment and obtaining the assembly configuration illustrated in Fig. 10 . Subsequently, the second branch 221 must be rotated relative to the first branch 220 in the way indicated by the arrow X, in order to obtain the assembly configuration illustrated in Fig. 11 . Starting from this configuration:
  • a residual current device in accordance with the present invention allows achieving the pursued objectives, in that the assembly of the device together with a circuit-breaker requires particularly simple and rapid operations.
