Definitions

  • the invention relates to a contact system with a two-arm contact according to the preamble of claim 1.
  • Such contact systems find particular application in current-limiting cherriesschaltem.
  • a contact system which has a two-armed, rotatable about a central bearing contact arm, which is provided at its ends on opposite sides of the axis of rotation of the bearing crossing longitudinal axis, each with a contact piece, in and out Connection can be brought with one contact piece of a fixed busbar and the lever arms is assigned to each one against a shift shaft supporting contact force torsion spring.
  • the mounting of the contact arm has a bearing pin and a bearing bolt enclosing peddes slot whose longitudinal axis extends approximately at right angles to the longitudinal axis of the contact arm.
  • the known contact systems ensure compensation even with asymmetrically decreasing height of the contact pieces, which occurs as a result of erosion or other wear of these contacts, by the displacement of the axis of rotation on the slot or on the floating storage.
  • the disadvantage is that at a non-uniform wear of the opposite ends of the lever arms attributable contacts in the displacement of the contact arm the two lever arms attributable contact force are applied differently and / or attack at different distances from the bearing axis of the lever arms and thus different contact forces between cause the connected contact pieces. This also has the effect that on the side of the most worn contact pieces reduces the contact pressure and thus a self-reinforcing further wear of the contacts is caused on this page.
  • EP 889 498 A2 shows a generic contact system with a rotationally symmetrical two-armed contact arm, which lies over a slot.
  • the slot runs counter to the opening movement of the contact arm obliquely to the longitudinal axis.
  • the direction of action between the ends of the Dodgekraftfedem extends in the closed contact system obliquely to the longitudinal axis of the contact, but not perpendicular to the slot.
  • the invention is therefore based on the object to ensure a uniform contact pressure at different wear of the contacts.
  • the invention proposes attack the Kunststoffkraftfedem between one of the lever arms on the one hand and a shift shaft or a switching shaft segment on the other hand as well as to let the direction of action of the contact force springs with respect to the longitudinal axis of the contact arm at an angle of 47 ° to 62 °.
  • the slot is offset by a first angle of 45 ° to 60 ° relative to the direction perpendicular to the longitudinal axis of the contact arm.
  • the Kunststofffedem are suitably designed as Switzerlandfedem; However, they are not limited thereto, but can be suitably used in other training, such as a pressure or Drehfedem, in a suitable manner for the invention.
  • the contact system 1 consists of a contact arm 3 which is rotatably supported by a slot 5 about a central bearing axis 7.
  • the rotationally symmetrical contact arm 3 consists of two lever arms 8 and 9, which are provided at their opposite ends, each with a movable contact piece 10 and 11.
  • the contacts 10, 11 occur in closed contact system 1, each with a fixed contact piece 12 and 13 on a busbar 14 and 15 in electrical connection.
  • the necessary contact pressure between the contact piece pairs 10, 12 and 11, 13 is generated by Divikraftfedem 17 and 18, with its one end 20 and 22 on a switching shaft segment 25 and with its other end 21 and 23 on one of the lever arms 8 and 9 attack.
  • the Kunststofffedem 17, 18 symbolically represented as Switzerlandfedem; However, they may also have other configurations, the longitudinal direction of action 26 in each case via the points of attack or ends 20 and 21 or 22 and 23 runs.
  • two contact force springs each are arranged on both sides of the contact arm 3, of which only the contact force springs 17 and 18 which are arranged with respect to the plane of the drawing in front of the contact arm 3 can be seen in the figures.
  • the slot 5 extends in a direction 27, both in the opening direction of rotation of the contact arm 3 (ie, clockwise in FIG. 1) substantially from the longitudinal axis 29 of the contact arm 3 and the bearing axis 7 perpendicular direction 28 as well as substantially from the longitudinal axis 29 makes a difference.
  • the direction of action 26 of the contact force springs 17 and 18 is neither perpendicular or approximately perpendicular to the longitudinal axis 29 of the contact arm 3 nor perpendicular or approximately perpendicular to the Clearrekkungscardi 27 of the elongated hole. 5
  • Fig. 2 the closed contact system 1 is shown for the case that the fixed contact piece 12 of the bus bar 14 is inferior to a nearly complete wear, whereas the remaining contact pieces 10, 11 and 13 are still completely preserved.
  • Under the action of the contact force springs 17 and 18 is along the slot 5 about the bearing axis 7, a displacement of Contact arm 3 takes place, which further ensures a reliable connection between the contact piece pairs 10, 12 and 11, 13.
  • the extension direction 27 of the elongated hole 5 described above, the direction of action 26 of the contact force springs 17 and 18 (FIG.
