Description

In the case of bundle conductor arrangements, the individual conductors of the bundle are in suitable spacers Maintained distance from each other. Clamps are attached to the sub-conductors, to which the spacers are attached directly or are articulated via spacers. To have sufficient mobility between the clamps and to maintain the distance gaps, there will be more or less large play between these components intended. Due to this play, however, the bundle conductor does not behave like a solid body, but the individual elements (ropes), which represent structures that can vibrate, have the option for themselves carry out vibrations alone. The bundle conductor then represents a structure that consists of several vibrating ^ active elements that are loosely coupled to one another. Such a structure can be common Perform vibrations, but also the individual elements (ropes) can each for themselves, z. B. by external causes, to be excited to vibrations, whereby the frequency, amplitude and phase position of the Vibrations neither match those of the other ropes nor with those of the entire arrangement got to. As a result, the ropes often start to oscillate at different frequencies, The amplitude and phase position takes place as long as there is play between the rope clamps and the spacer elements there is little or no coupling between the ropes. This game becomes so Overcome faster, the stronger the phase position, frequencies and amplitudes of the vibrations of the individual Ropes differ from each other. Spacers and clamp meet, being part of the kinetic Transferring energy from the vibrating ropes to the contact point (joint) on the other ropes or needs to be implemented. This process naturally involves great mechanical forces which according to the invention lead to severe wear and tear and premature destruction of the joints.

But there are already known spacers in which between the interconnected Elements elastic intermediate elements are switched on. In these known arrangements but then no free game available.

The invention relates to the connection of bundle conductor terminals and spacer frames or Intermediate piece, in which there is also an elastic intermediate piece between the cable clamp and the spacer element is arranged. According to the invention, however, one is effective at least in one direction of movement free play is provided between the elastic intermediate member and rope clamp or spacer element. If you now consider the effects of the different types of fastening variants according to the known and according to the

subject of the report to the movement of the whole system, the following is shown: In the case of the invention Connection, rope oscillations of lower amplitude are passed through completely unhindered, since free play does not in any way prevent rope movement to a lesser extent. Will However, if the rope amplitudes are larger, the elastic element will respond, and so will the rope oscillations will be dampened without causing the connecting elements to hit each other hard comes. This hard knocking (hammering) is extremely undesirable in such connections because it can damage the connection in a very short time. In the case of acquaintances, on the other hand, result the resilient holding together by the elastic intermediate element also low amplitudes of the rope rigidly transferred to the whole system. The combination according to the application of a resilient intermediate element and a free game has the advantage that the system has little rope vibrations influence, while larger rope vibrations are effectively dampened. Such an effect can, of course, if the combination elements are used separately (free play - elastic Intermediate element) cannot be reached.

The figures show an exemplary embodiment. 1 with the bundle ladder rope is referred to, on which the rope clamp 2 is seated. The spacer (spacer frame
