Definitions

  • a known differential switch of the kind mentioned is described with reference to Figures 10 to 13 of French patent No. 2,475,291 of the applicant.
  • This device is derived from a four-pole version from which the electrical contact and connection elements of two poles have been eliminated.
  • the insulating bolt and the mechanism are standard for both four-pole and two-pole versions. This results in poor optimization of the bipolar version, which also has a large transverse size.
  • the object of the invention is to remedy these drawbacks and to allow the production of a bipolar differential switch with a compact structure suitable for a reduced bulk of the housing.
  • the switch according to the invention is characterized in that the operating mechanism is housed between a first and a second fixed plates extending at the same time parallel to the longitudinal direction of alignment of the terminals of each pole, and perpendicular to the front face of the box, the first plate constituting the main support of the self-supporting structure of the electromechanical block, and that the contact system and the differential transformer are arranged on the same side of said first plate, and at different levels in the direction perpendicular to the front face, the operating mechanism and the tripping relay being respectively juxtaposed transversely with the contact system of the upper level, and with the transformer lower level differential.
  • the second plate is shorter than the first plate of the mechanism, the latter being advantageously provided with an extension extending in the direction of the depth of the case up to the vicinity of the support base opposite the front face. . This extension serves as a support for the trip relay.
  • the compact arrangement of the functional electromechanical block with self-supporting structure allows a significant reduction in the width of the box and facilitates the insertion of the preassembled block in the box with two parts mounted to interlocking.
  • FIGS. 1 to 9 show a bipolar differential switch 10 at: low voltage, used in a single-phase alternating network with neutral.
  • the switch 10 is housed in a rectangular housing 12 made of molded insulating material, formed by the assembly of two parts 14, 16 anterior and posterior.
  • the rear part 16 of the housing 12 (FIGS. 5 and 6) has a U-shaped profile, the base of which is provided on the outside with a base 18 for snap-fastening to a support rail (not shown).
  • the internal face 19 of the base serves as a support for the functional electromechanical block 20 (FIGS. 3 and 4) associated with two pairs of connection terminals 22, 24 of the neutral and of the phase.
  • the front part 14 of the housing 12 (FIGS. 1 and 2) comprises a cover 26 fitted to interlock on the opposite wings 28, 30 of the U of the other part 16.
  • the face 19 of the rear part 16 is equipped with two guide pins 32 which engage vertically in notches 34 conjugate of the cover 16 to ensure the correct positioning of the two parts 14, 16 during assembly of the housing 12.
  • the latter also has holes 36 aligned for the 'introduction of fixing means (screws or rivets) of the two parts 14, 16.
  • the front face 38 of the cover 26 is pierced with two openings for passage of the handle 40 of the operating mechanism 42, and of the test button 44 of the test switch 46.
  • Sockets 48 are provided at the four corners of the front part 14 for housing the terminals 22, 24 for connecting the neutral and the phase, the two sockets 48 located on the same side being isolated of the internal volume 49 of the cover 26 by a common intermediate wall 50 extending transversely over the entire width of the housing 12.
  • Each opening 48 is associated with an orifice 52 in the housing 12 for access to the screw 54 for tightening the corresponding terminal 22, 24.
  • the functional electromechanical unit 20 (fig. 3, 4, 8 and 9) comprises a self-supporting structure grouping together the various constituent elements of the differential switch 10.
  • the operating mechanism 42 is arranged between two fixed plates 56, 58 parallel to the direction longitudinal alignment of the input 24 and output 22 terminals of each pole, one 56 of the plates being extended downward to abut against the bearing face 19 of the housing.
  • the other plate 58 is lower than the plate 56 and carries on its external face an insulating support 60 provided with the test switch 46 and a resistor 62 electrically connected in the test circuit.
  • the switch 46 is formed by a spiral spring 63 threaded on a stud 64 of the support 60, and with a free end cooperating elastically with the test button 44.
  • the resistor 62 is inserted into a cylindrical housing 66 of the support 60 and has a conductor 68 of folded connection serving as fixed contact to the test switch 46.
  • the closing of the test switch 46 is controlled by depressing the test button 44 which connects the resistor 62 so as to simulate an artificial fault and check the correct operation of the differential protection.
  • the test button 44 and the support 60 of the switch 46 are located in the longitudinal plane corresponding to the movement of the lever 40, which is pivotally mounted on an axis 70 perpendicular to the two plates 56, 58.
  • a polarized relay 72 with a trigger coil 74 and a movable paddle 76 cooperating with a latch 78 for triggering the mechanism 42.
  • the latter further comprises an automatic reset lever 80 for the paddle 76 during the opening of the switch 10.
  • the relay 72 extends longitudinally in the lower interval separating the terminals 22, 24 from one of the poles, and is secured to the central plate 56 by suitable fixing means.
  • a differential transformer 82 with toroidal core extends longitudinally between the terminals 22, 24 for connection of the other pole while being juxtaposed by its internal front face to the relay 72 with interposition of the plate 56.;
  • the core of the transformer 82 is traversed in the width direction by primary windings 84 electrically connected to a contact block 86 and to the output terminals 22 of the phase and the neutral.
  • the differential transformer 82 includes a secondary winding electrically connected to the trip coil 74 of the polarized relay 72.
  • the contact block 86 is arranged above the differential transformer 82 in the upper part of the cover 26, and is attached to the plate 56 opposite the mechanism 42.
  • the block 86 contains two movable contacts secured to a coupled slide to mechanism 42 for opening and closing the phase and neutral contacts.
  • the contact block 86 and the transformation t differential eur 82 are located on the same side of the platen 56 and at different levels, being respectively transversely juxtaposed with the actuating mechanism 42 of the upper level and the relay polarized 72 from the lower level.
  • This compact arrangement makes it possible to significantly reduce the width of the housing 12, and the four connection terminals 22, 24 lie in a plane perpendicular to the plate 56.
  • the latter is the main element of the self-supporting structure of the electromechanical block 20 of the bipolar switch 10, and extends substantially in the median plane separating the terminals 22, 24 of each pole
  • the assembly of the electromechanical block 20 takes place outside the insulating housing 12.
  • the mounting of the various constituent elements of the switch on either side of the self-supporting plate 56 is followed by the welding of the connection conductors to the four terminals 22, 24 of the phase and of the neutral.
  • the mounted block 20 is then positioned on the support base 19 of the. rear part 16, and the housing 12 is then closed by placing the front part 14 during which the terminals 22, 24 fit into the corresponding cells 48 of the cover 26.
