Definitions

  • Such contactor arrangements are z. B. from DE 195 48 480 C1 or DE 24 40 361 A1.
  • a contactor arrangement with two contactors and a blocking element in which the contactors have guides for contact carriers, the blocking element is deflected upon actuation of one of the contactors of the guide of the operated contactor from an intermediate position to a blocking position, in the actuation of the unactuated contactor is locked, and in an attempt to actuate the unactuated contactor, the leadership of the unactuated contactor acts on the blocking element in an operating area.
  • the guides act on pins on the locking element.
  • Electrical loads are often connected to a supply network in a variety of ways.
  • Example of such types of connection are the optional connection of a load in star or delta connection to a three-phase system or a reversing circuit, in which either a DC voltage is reversed or a three-phase network once left-handed and once right-handed connected to a load.
  • connection of the electrical load to the supply network is usually via contactors. If both contactors operated simultaneously, this would result in a phase short circuit. Such a simultaneous actuation of both contactors must therefore be prevented. This is achieved in the prior art with the contactor arrangements mentioned.
  • the object of the present invention is to provide a contactor arrangement in which the guides act directly on the blocking element and yet no fatigue phenomena occur in the blocking element.
  • the object is achieved in that essentially only compressive forces occur due to the actuation attempt in the blocking element.
  • the invention is based on the finding that the fatigue of the locking elements or the pins on tensile and / or bending stresses is due. At substantially pure compressive stress, however, virtually no material fatigue occurs.
  • the contactor arrangement is structurally particularly simple if the contactors are facing each other with side surfaces, the blocking element is arranged in a blocking element receptacle and the blocking element receptacle is arranged between the contactors.
  • An occurrence of essentially only compressive forces in the guide of the unactuated contactor is structurally particularly easy to implement if the blocking element is pivotable in a pivot plane which is perpendicular to the side surfaces.
  • the mechanical structure is even easier when the guides act in an actuating direction on the locking element and the actuating direction is parallel to the side surfaces.
  • the contactor arrangement requires a small footprint. The space requirement is minimal if the side surfaces adjoin one another.
  • the contactors each have a front side and a rear side opposite the rear side and the back sides and the blocking element receptacle are flush with one another, a defined positioning of the blocking element results forcibly. Adjustments are no longer required.
  • the blocking element is designed as a turning heart, the blocking element works particularly reliable.
  • the contactors can be designed as desired. As a rule, however, at least three load contacts can be actuated via the contact carriers.
  • the 1 shows two contactors 1. One of the contactors 1 is shown in detail, the other contactor 1 indicated only schematically.
  • the shooter 1 are facing each other with side surfaces 2. Between the shooters a blocking element holder 3 is arranged.
  • the contactors 1 spaced from each other.
  • the side surfaces 2 adjoin one another.
  • the blocking element holder 3 is completely or partially sunk in the shooter 1.
  • the contactors 1 each have a front side 4 and a front side 4 opposite back 5.
  • the backsides 5 and the blocking element receiving 3 are flush with each other.
  • the blocking element holder 3 has a clear receiving width B.
  • a blocking element 6 is arranged in the blocking element holder 3. It has a blocking element width b, which is slightly smaller than the light receiving width B.
  • the blocking element is held pivotably in the blocking element receptacle 3 in a pivoting plane 7.
  • the receiving width B extends perpendicular to this pivoting plane 7.
  • the side surfaces 2 and the pivoting plane 7 are perpendicular to each other.
  • the contactors 1 have guides 8 for contact carrier.
  • the contact carrier in each case at least one load contact can be actuated.
  • at least three load contacts can be actuated via the contact carrier.
  • the blocking element 6 is formed according to FIGS 2 and 3 as so-called turning heart 6. It has a heart top 9 and operating areas 10. If both contactors 1 are inoperative, the turning heart 6 is held by a return spring 11 in an intermediate position, which is shown in Figures 2 and 3. By way of example, it is assumed below that now first the left of the two contactors 1 is actuated and then it is attempted to actuate the right of the two contactors 1.
  • the actuation direction x is parallel to the side surfaces 2 and parallel to the pivot plane 7.
  • the apex 9 of the locking element 6 is deflected into a receiving chamber 12, which is arranged substantially below the guide 8 of the right contactor 1.
  • the guide 8 acts directly on the blocking element 6 in the actuating region 10, which lies within the blocking element width b and thus in particular also the receiving width B.
  • the guide 8 of the right contactor 1 exerts an actuating force F in the actuation attempt on the blocking element 6 in the actuating direction x. Due to the action within the receiving width B, the actuating force F but directly, ie in particular without deflection and thus without the occurrence of shear forces transmitted to the blocking element receiving 3. So there are - and in both the guides 8 and in the blocking element 6 - essentially only compressive forces, but no tensile and shear forces.
  • the shooter 1 can, as already mentioned, be designed arbitrarily. In particular, both training as air contactors and training as vacuum contactors is possible. A combination of an air contactor with a vacuum contactor is also possible.
