Definitions

  • the known means of transmission of the mobile contacts of all the poles have either a switching slide movable in translation by means a control mechanism positioned on the lateral side (FR-A-2 530 373), either a common rotary bar actuated by a link of a knee switch.
  • a slide or a rotary support shaft for all moving contacts requires constraints of positioning and architecture, and requires different achievements depending on the four-pole or three-pole type.
  • the object of the invention is to provide a multi-pole switch with mounting fast, using the maximum of standard elements to go from one version tripolar to a four-pole version.
  • each elementary switching bar have a drive tab arranged at the upper end of the stud, and a transmission ring surrounding said tab, and further having two pins inserted in holes in the rods
  • the two actuation rods work respectively in tension and compression following the action of the rods on one of the rings of an intermediate pole.
  • the connecting rods have ends positioned in grooves of a main pinion of the device to gables.
  • the main gear is in mechanical connection with a bevel gear by via a return pinion, and a removable operating handle is adaptable either to the main gear or to the bevel gear to ensure front control or side control.
  • the housing is advantageously formed by the superposition of a housing base for compartments of the unipolar modules, of an intermediate casing containing the means for driving the pads and the actuating rods, and a cover positioning of the control mechanism.
  • All unipolar switching bars have identical structures bearing each a mobile double bridge contact formed by two conductive bars parallel crossing lights of the insulating pad, being separated from each other by a predetermined interval, and cooperating on one side with a first fixed contact in connection with one of the connection terminals, and on the opposite side with a second fixed contact in connection with the other connection terminal of each pole.
  • a low-voltage multi-pole electrical switch 10 tension and strong calibers is housed in a box 12 parallelepiped in material molded insulator, formed by the superposition of a base 14, an intermediate casing 16, and a cover 18.
  • the internal volume of the base 14 is subdivided by partitions 20 parallel in several compartments 22, 24, 26, 28 for housing switch modules 30 single-pole arranged side by side in the housing 12.
  • an additional compartment 32 which can be used for placing auxiliaries electric signaling 33 of the open or closed position.
  • the width of the additional compartment 32 is less than that of each compartment 22,24,26,28 of switch modules 30.
  • the single-pole switch modules 30 are identical and constitute the different of the switch 10, which in the example described, is a four-pole switch.
  • Each single-pole switch module 30 includes a switching bar 34 individual rotary equipped with a movable double contact 36 in bridge (figure 6) cooperating with two opposite fixed contacts 38.40 (figure 2 and 4) to create a double current interruption by pole.
  • the rotary switching rod 34 with vertical axis of each pole is formed by a pad 42 of insulating material, provided with a cylindrical end piece 44 at its end lower, and a drive tab 46 at its upper end.
  • End piece 44 is housed in a blind notch 48 of circular section formed in the bottom of the base 14 to constitute a rotating guide member or bearing located in the area median of compartment 22,24,26,28 of the corresponding pole.
  • the height of the stud 42 insulation is slightly greater than the vertical offset between the bottom of base 14 and the horizontal wall 16A of the intermediate casing 16.
  • the drive tab 46 crosses a circular orifice 50 provided in the horizontal wall 16A of the casing 16, and is coupled at each pole to a transmission ring 52, which is provided with two diametrically opposed lugs 54.56.
  • Leg 46 and the ring of transmission 52 constitute the drive means of the bar 34.
  • the elementary switching bars 34 of all the poles extend parallel to each other in a vertical direction perpendicular to the wall 16A, and are staggered at regular intervals, being moved in rotation limited to by means of two actuating rods 58.60 piloted by a mechanism control 62.
  • the two elongated rods 58.60 are positioned parallel between them on the upper face of the horizontal wall 16A of the casing 16, and each has a series of circular holes 64 into which the lugs 54, 56 of the various transmission rings 52.
  • the control mechanism 62 is common to all of the bars 34 of the single-pole modules 30, and is arranged in the cover 18. It comprises a device for double toggle 66 associated with a pinion device 68 with front actuation or lateral.
  • the double toggle device 66 is arranged between two flanges 70, 72 metal parallel to the wall 16A, and is composed of two pivoting 74,76 levers hinged together by means of an intermediate lever 78 ( Figure 1). Both joints of the double toggle joint 66 are crossed without play by two rods of 80.82 parallel links projecting on either side of the flanges 70.72, and finding in contact with a circular sector 83 of the flanges.
  • the extremities upper rods 80,82 are positioned in drive grooves of a main control gear 84, which is rotated by a handle maneuver 86 accessible from the outside.
  • the lower ends of the two connecting rods 80,82 cooperate with two bearing surfaces of an intermediate ring 52 for moving the rods 58.60 according to opposite directions of translation during the change of state of the knee switch 66 operated by the pivoting of the operating handle 86 in the direction of opening or closing.
  • a compression spring 92.94 is threaded on each lever 74.76 of the toggle joint device 66 bearing on the connecting rod 80.82 corresponding.
  • the operating handle 86 is coupled directly to the main pinion 84 after introduction according to arrow F1 through a orifice 96 of the cover 18 (FIG. 5).
  • Lateral control is also possible by coupling the handle maneuver 86 to a bevel gear 98 in the direction of arrow F2. Movement of the bevel gear 98 is transmitted to the main gear 84 by via a return pinion 100.
  • the orifice 96 is free, and allows the adaptation of a position detector (not shown) allowing control visual of the closed or open state of the multi-pole switch 10.
  • the actuation of the electrical signaling auxiliaries 33 is operated at the end of lateral bevel gear 98 rotational stroke thanks to the intervention of a slide 88.
  • the movable double contact 36 of each switching rod 34 comprises two parallel busbars 36A, 36B passing through opposite lights 102 of the pad 42, being separated from each other by a predetermined interval d ( Figure 6).
  • a contact pressure spring 104 is arranged inside the stud 42 extending perpendicular to the bar 36B.
  • the double contact bridge 36 of each pole cooperates on one side with the first fixed contact 38, and on the opposite side with the other fixed contact 40.
  • Each pair of contacts 36,38; 36,40 is associated with an interrupting chamber 106 with sheets of deionization.
  • the two fixed contacts 38.40 of each switch module 30 each extend by a connection pad 108, 110 cooperating respectively with a cage of connection terminal 112,114.
  • the cross-section of the bars 36A, 36B constituting the double movable contact 36 can be cylindrical or rectangular.
  • the operation of the multipole switch 10 according to FIGS. 2 to 5 is as follows: In the closed position illustrated in FIGS. 2 and 4, the fixed contact 38.40 of each pole is inserted between the clamps of the two bars 36A, 36B of the movable double contact 36.
  • the input edge of the fixed contacts 38.40 is advantageously chamfered to facilitate entry of the clamp at the end of the closing stroke.
  • the separation of the contacts for opening the switch is done by rotate the operating handle 86 a quarter of a turn.
  • the rotation of the pinion main 84 causes a change of state of the double toggle device 66, and the opposite translation of the actuating rods 58.60 by the action of the 80.82 rods.
  • the rod 58 is thus moved to the right, while the other rod 60 is biased in the opposite direction to the left.
  • the displacement in translation in opposite directions of the two rods 58.60 takes place in synchronism, and causes a simultaneous rotation of the bars of 34 elementary switching of all poles.
  • the rod 58 works in traction, while a pushing force is exerted on the rod 60 which works in compression during the opening phase of the switch. Mechanical stresses on 58.60 rods are reversed during the closing phase.
  • the same standard elements can be used to make a switch tripolar.
  • the switching bars 34 are identical, it suffices to replace the 58.60 rods by shorter rods, and make use of a three box unipolar compartments.
