Definitions
- Busbar arrangement with a first and a second sub-conductor
- the invention relates to a busbar assembly having a first and a second spaced apart, a gap limiting, each other electrically conductively connected part conductor having busbar section which extends along a longitudinal axis and with a
- busbar portion Surrounding busbar portion, spaced therefrom arranged and filled with a fluid encapsulating housing.
- busbar arrangement is known for example from the published patent application DE 20 16 957. There are described various busbar sections having interconnected sub-conductors. Between the sub-conductors extend gaps. The busbar section is arranged within an encapsulating housing.
- the known sub-conductors are connected to each other via a web.
- Insulator arrangements for supporting the busbar section on the encapsulating housing engage the bridge. Heat is generated when the conductors are subjected to an electric current. Due to the selected location of
- Partial ladder to each other and the use of webs arise gaps in which heat can accumulate. On other columns, in turn, there is a rapid outflow of heat generated at the busbar section.
- the busbar section may have at least two, in particular, three sub-conductors.
- the number of sub-conductors with respect to a cross-section to the longitudinal axis can be varied almost arbitrarily.
- the basis for the choice and design of the sub-leaders is that the sub-conductors in their interaction provide a circular envelope contour. As the number of sub-conductors increases, so should the number of gaps breaking through the envelope contour. It is advantageous if the number of gaps corresponds to the number of subconductors reduced by 1.
- a breakthrough of the envelope contour through a gap can, for example, take place such that the gap in the radial or tangential direction penetrates into the cross section and provides a recess between the partial conductors.
- the gap forms a channel which divides the circular envelope contour in cross-section and is filled with the fluid.
- the resulting channel can be filled with a fluid.
- the fluid is, for example, a gas or a liquid, which preferably has electrically insulating properties.
- the channel is preferably formed between the sub-conductors and limited by these.
- the fluid flows around the busbar section in the interior of the encapsulating housing.
- the encapsulating housing is designed correspondingly fluid-tight. This makes it possible to provide the interior of the encapsulating housing with a fluid which is separated from the environment of the encapsulating housing.
- the fluid flows around the busbar section and wraps around the circular envelope contour. Due to non-existent projections or undercuts on a circular envelope contour, a slight flow around and forwarding of heat arising at the busbar section is made possible.
- the use of the channel, which pierces through the busbar section is possible in order to flow fluid into this channel. In this case, this channel can also be used to dissipate heat from inner regions of the busbar section.
- it can be provided, for example, that two partial conductors are formed in a circle segment shape in cross section, wherein the gap is formed in the busbar section between opposing surfaces of the two partial conductors. This gap then acts as a channel, which conducts heat out of the interior of the busbar section.
- the gap is bounded by parallel planar walls of the sub-conductor and the flat walls are aligned parallel to a diameter of the envelope contour.
- Diameter of the envelope contour makes it possible to provide several gaps on a busbar section.
- the several gaps within the busbar section are approximately parallel to one another.
- the surface of the busbar section in comparison to a massive busbar section of the same envelope contour, the
- the sub-conductors abut the end face on an end fitting and are contacted with this electrically conductive.
- the sub-conductors are fixed to each other and set the gap between the sub-conductors in their dimension.
- the sub-conductors can be contacted with each other electrically conductive.
- the sub-conductors can be contacted via the end fitting with other busbar sections electrically conductive.
- Further busbar sections may be designed in alternative forms, for example in conventional tubular or cylindrical form. However, similar busbar sections or other shaped busbar sections may be coupled together with otherwise configured sub-conductors.
- About the end fitting is a way to space the busbar portion relative to the encapsulating.
- an encapsulating housing a substantially tubular structure, along the tube axis of which the longitudinal axis of the busbar section is obtained. stretches.
- a support can be carried out by columnar insulators, which support an end fitting together with attached thereto partial conductors on an inner circumferential surface of the encapsulating.
- disk insulators are arranged, for example, at the front ends of an encapsulating housing, these disk insulators terminating the encapsulating housing in each case.
- a busbar section can be electrically conductively contacted through a wall of the encapsulation housing by way of end fittings embedded in the disk insulators.
- the encapsulating housing can be followed by further encapsulating housings or contacting outside of the encapsulating housing of the busbar section.
- the sub-conductors can be made by milling in a preferably round solid conductor, the milled not be carried out to the end of the conductor and thus at the end of the sub-conductor, the starting material remains as an end fitting.
- a further advantageous embodiment can provide that the end fitting is bolted to each of the adjoining sub-conductor, wherein screwing are arranged evenly distributed lying on a circular path.
- Screwing of partial conductors with the end fitting offers the possibility of building a modular busbar assembly in a modular manner and of combining differently shaped partial conductors with differently shaped end fittings.
- a modular design of the busbar arrangement is given and depending on the expected boundary conditions or requirements for the current carrying capacity of the busbar arrangement, various design variants of the busbar section can be performed.
- a screw allows it a relatively simple connection of the individual sub-conductors.
- the glands can for example also be repeatedly loosened and tensioned.
- By using a circular path on which the screw connections lie it is possible to use standardized circular paths, so that interchangeable partial conductors and end fittings can be used.
- each sub-conductor is connected to the end fitting via at least two screwed connections.
- each sub-conductor allows a twist-proof connection of the sub-conductors to the end fittings. Furthermore, a modularity of the structure is thereby supported. In combination with the circular path and the evenly distributed on this glands, the position of the individual sub-conductor is zueinan- set about the at least two glands each subconductor, so that almost inevitably creates a circular envelope contour during assembly. As a result, assembly errors are prevented and ensures a high quality of the busbar assembly.
- the end fitting is materially connected to the sub-conductors.
- a cohesive composite of the end fittings is advantageous if a permanent connection is desired. It can be dispensed with the provision of additional elements, such as screws, nuts, tapped holes, etc.
- a cohesive bonding can be done for example by welding, soldering, gluing or the like.
- the sub-conductors can be made by milling into a preferably round solid conductor, the milled not be carried out to the end of the conductor and thus at the end of the ladder, the starting material remains as an end fitting.
- the channel is flowed through by the fluid in the vertical direction.
- the natural convection can be used to generate on the surfaces of the sub-conductor, in particular within the column, a fluid flow and to derive heat automatically.
- a further advantageous embodiment may provide that a first, a second and a third sub-conductor are arranged along the longitudinal axis, wherein the second sub-conductor is flanked in cross-section by the first and third sub-conductor and the first and the third sub-conductor have a similar cross-section.
- the use of three sub-conductors makes it possible, for example, to provide two slits on the bus-bar section through the entire cross-section of the busbar section in the form of slits.
- the second sub-conductor has a substantially rectangular cross section, wherein two opposing sides th are curved in cross-section arcuate in order to limit the circular envelope contour.
- the two first and third sub-conductors flanking the second sub-conductor should preferably have the shape of a circle segment in cross-section.
- the chords of the circle segments should be parallel to a diameter of the circular envelope contour.
- the width of the gap formed between the first and the second or between the third and the second conductor can vary.
- To adjust the width of the gap may continue to vary the strength of the second sub-conductor.
- the gap in the mouth region of the envelope contour widens like a funnel.
- a funnel-like extension transverse to the longitudinal axis of the gap allows the configuration of a dielectrically favorable shaped busbar section.
- voltages in the high and very high voltage range ie from several tens to several 100,000 volts, for driving the electric current flowing through the busbar section.
- a simplified inflow or outflow of the busbar section passing through the fluid is made possible by the funnel-like extension.
- the flow or the flow course in the interior of the encapsulating can be additionally positively influenced.
- the sub-conductors are interconnected via the gap within the envelope contour passing spacers.
- the gap is at least partially interrupted.
- a breakthrough of the envelope contour is favored by a plurality of columns in cross section.
- the spacers are located within the gap between the sub-conductors in a dielectrically shielded zone, since the sub-conductors all carry the same electrical potential.
- the shape of the spacers for example, preferably be optimized for their mechanical properties, since the consideration of dielectric conditions in a shielded zone is not necessary.
- these should preferably be spaced from each other, so that between the spacers within the gap further a channel is formed, which may be flowed through by a fluid.
- a further advantageous embodiment may provide that the spacers electrically conductively connect the sub-conductors.
- the spacers can be connected, for example, cohesively with the sub-conductors.
- the busbar section is formed with its corresponding sub-conductors in the context of an extrusion or rolling process, wherein the spacers are arranged in the form of webs within the columns. In this case, the webs can be subsequently broken or already formed only in sections during manufacture, so that channels are made available within the column, which can be flowed through by a fluid.
