Definitions

  • the invention relates to a busbar arrangement for an electrical switchgear, in particular for an electrical switchgear in double-front design.
  • Switchgears have for some time not only been designed as a front-end arrangement but also as a double-front arrangement.
  • the double front arrangement is designed in such a way that the system has an operating front both at the front (front) and at the rear (rear).
  • the double front arrangement has a common busbar system.
  • the connections of field rails are made from the front as well as from behind to the common, centrally located busbar.
  • the busbar is held by we ⁇ least one busbar holder.
  • German patent application DE 103 32 679 Al is a multi-pole busbar system for switchgear in
  • Double front construction described.
  • the individual rails are arranged in a plane and with a certain minimum distance from each other.
  • phase rails are often used, which are divided into several (usually two or four) sub-conductors. In the low-voltage range, such a subdivision is mostly used to control the eddy current To reduce losses. For a simultaneous connection of devices to the busbar from the front and back a complex system was necessary to avoid a collision of rail connections with each other. In particular, in double front arrangements beyond that
  • An object of the present invention is to provide a structurally relatively simple busbar holder, which is universal and particularly for double ⁇ front assemblies used.
  • Claim 1 solved. Thereafter, it is provided that the busbar holder is arranged between a first sub-conductor group and a second sub-conductor group.
  • the first sub-conductor group comprises at least two first (front) sub-conductors and the second sub-conductor group comprises at least two second (rear) sub-conductors.
  • These four sub-conductors are arranged in a rectangle, wherein the sub-conductors of a sub-conductor group are preferably aligned in each case transversely to the busbar longitudinal direction to each other.
  • the busbar support between the partial conductors is so to speak, arranged within the space formed by the conductor rectangle, it also does not build on the part ⁇ on ladder. He instead has an extremely compact construction ⁇ form, so he that is very space-saving.
  • the busbar holder is therefore not, as known from the prior art, one or both sides of the outside of the busbar disposed, but is quasi in the space between the individual sub-conductors of the busbar and holds the sub-conductors from the inside. This provides the largest possible connection area for the connection rails.
  • an independent electrical connection from the front and from the rear to achieve a double-front arrangement can be done easily.
  • the busbar holder does not get in the way of such a two-sided connection.
  • the busbar holder can be used for busbar cross-sections of 20x5 to 50x10, whereby more than one conductor can be used per phase.
  • bus bar holder according to the invention can be used not only for single-front and double-front arrangements but also for "power center arrangements" in which the busbar system is arranged twice in succession (current carrying capacity up to 6300 A.)
  • the busbar holder is not only for a busbar - can be used in the rear, in the center and in the "Power Center", but can also be placed on the left or right or in a center-symmetrical manner above or below in a control cabinet.
  • This universal application not only reduces development and production costs ⁇ is possible. Warehousing and deployment costs can also be reduced.
  • the significantly improved short-circuit properties of the busbar holder arranged between the partial conductors are of advantage.
  • the force is introduced into the busbar holder by the proposed solution in such a way that the busbar holder is hardly exposed to a bending load.
  • the busbar holder according to the invention therefore only needs to be designed for the tensile forces acting in the event of a short circuit. Since thus in the selection of materials and the structural design of the Busbar holder savings can be made, the production of the busbar holder can be significantly cheaper. Another advantage is the universal applicability for phase and N / PEN conductors.
  • the busbar holder on two basic body elements which are preferably ⁇ identical before. These are preferably so connected to ⁇ each other, that a symmetrical construction of the bus bar holder is obtained.
  • a simple structure of the desired busbar holder it is also possible to use a one-piece busbar holder.
  • the assembly of the conductors is often easier. This is especially true when using six sub-conductors, since there the middle sub-conductor can be very easily inserted and mounted between the two basic body elements, when the base body elements are connected for mounting the sub-conductor correspondingly loosely.
  • the current distribution can be improved. Due to the more uniform distribution of current in such a sub-conductor arrangement rail material (in particular copper) can be saved.
  • a higher rated current of the busbar in the case of a double front arrangement becomes possible in comparison to known solutions.
  • the cross sections per phase can be designed, for example, for rated currents over 4000 A.
  • the middle sub-conductors carry little power. This results in an unfavorable ratio of cross section per phase to transmittable current. Therefore, according to a further embodiment of the invention, the middle sub-conductors can be designed such that they project beyond the front and rear sub-conductors transversely to the busbar longitudinal direction. In other words, the middle sub-conductors are offset outwards, thus higher than the outer sub-conductors and überra ⁇ gen these.
  • the busbar holder has preferably at least one on ⁇ receiving opening for receiving at least a portion of the conductor of the third conductor group. If only four sub-conductors are used, the receiving opening, which is preferably designed in the form of a continuous receiving channel, can also be provided with a preferably non-conductive filling piece. These fillers or intermediate pieces fulfill a mechanical support function and thus ensure the stability of the overall construction even under high loads.
  • screw solution has the advantage of eliminating the need for separate mounting hardware, such as the mounting bracket, but the sub-conductors must be provided with screw-threaded holes for this purpose, both of which have specific advantages and advantages in practical tests excellent results in terms of low-cost production, easy installation and secure fastening of the busbars.
  • the "clip solution” is characterized in particular by the fact that at least one sub-conductor of the first or second sub-conductor group rests in a guide on the outer side of the busbar holder
  • the guide is provided by a fixedly arranged on the outside of the busbar holder and preferably in the manner of web

  • the guide is preferably of the ⁇ configured such that the conductor fixed rests in the guide, without, however, by the guide element or crab-positively in the sense of a press fit connection In other words, there is preferably a merely form-fitting connection, which is held in the guide.
  • the mounting bracket is designed such that it is the same time ⁇ on both outer sides of the busbar holder on ⁇ .
  • the mounting bracket then engages around the busbar holder so that on both sides of the busbar holder has a guide is formed for a portion of conductor ⁇ , if a corresponding counterpart, as in ⁇ play, a bar-shaped guide member is present.
  • a screw connection is preferably provided which preferably completely penetrates the legs of the fastening clip.
  • the position is secured according to a further embodiment of the invention by means of a screw connection. It is particularly advantageous if the screwing takes place at the edge of the sub-conductor, since then no opening has to be made in the sub-conductor.
