Abstract
The supply system based on bus/current collector has the current rail (1) provided with successive energy supply sections (1.1,1.2) which can be coupled together or separated from one another, with a cooperating current take-off (2) used for supplying an energy supply unit onboard a vehicle. Each energy supply section (1.1,1.2) has a current rail end piece (6) mechanically coupled via an insulation piece (4) with a current rail centre piece (5), with briding diodes (7.1,7.2) across the insulation pieces (4) of the adjacent energy supply sections having the same poles facing the separation gap (3) between the latter (6).
Description
Technical field
The present invention relates to a kind of electric power system based on bus duct/current colector, wherein, described bus duct has feed section separation or coupling, and at least one current colector provides electric current for a feed element of vehicle.This bus duct be interpreted as divide in the feed section, for different traffic systems provide galvanic electric electric power system, be the top trolley wire especially equally.Up to now in this electric power system because some significant problems appear in undesirable electric current and arc of lighting.
Background technology
All by the vehicle of one or more current colector power supplies that are electrically connected and spatially separate, relate in particular to so-called transverse current for its each polarity by relay and/or this vehicle.This transverse current drives by the voltage difference with separated part feed section adjacent one another are.
On a current colector, undesirable electric current may appear by this current colector at the separated part between the feed section.
In addition, under thousands of amperes high gross vehicle electric current for example, may cause strong arc of lighting.
These problems are to solve (WO 99/03700 A1) by interval bigger between continuous mutually feed section or separated part so far.But, influenced the continuity that electric current guides thus, however, only can realize the mitigation rather than the gratifying solution of this problem here.
Build isolated bus joint (Gleisbau-Isolier-Schienenstoesse) for track and in DE3636863 A1, a kind of cross-over connection is set, be connected by a rectification film and bus duct are terminal respectively in the both sides of this cross-over connection by fish plate.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of electric power system of mode according to type is provided, and wherein avoids undesirable electric current and reduces arc of lighting.
According to the present invention, above-mentioned technical matters is to solve by such feature, be that the feed section has the insulating segment by separately and the bus duct end segment of a bus duct interlude mechanical connection, wherein, described insulating segment is by the diode cross-over connection, and the identical separated part of polarity between the bus duct end segment of diode.Having guaranteed not run through electric current by reverse bonded assembly cross-over connection diode can circulate.The length of bus duct end segment must adapt with the configuration of current colector separately on separated part.As long as the current colector that is electrically connected is positioned at the front of separated part, then the power supply to vehicle realizes by each self feeding section or by the bus duct end segment of diode by the feed section.If current colector or current colector configuration cross-over connection the separated part between the bus duct end segment, then oppositely the bonded assembly diode stops electric current by adjacent feed section.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing, among the figure,
Fig. 1 schematically represents prior art,
Fig. 2 represent according to the structure of the present invention's bus duct on different current colectors position and
Fig. 3 represents the bus duct structure in detail.
The specific embodiment
Fig. 1 shows for two the diverse location a of current colector 2 and the bus duct 1 of b conventional configurations type, and this current colector is connected with a feed element of vehicle.Bus duct 1 is divided into the feed section, and wherein two section 1.1 and 1.2 is partly illustrated.Between feed section 1.1 and 1.2, has separated part 3.According to a, have the current colector 2 cross-over connection separated parts 3 of contact point 2a and 2b among the figure.This contact point 2a and 2b can be the moving contact points.Obviously, at this position a, almost all electric current I flows to follow-up feed section 1.2 from feed section 1.1 by current colector 2.This electric current illustrates by a dotted line.Be on the position b of separated part 3 at current colector 2 contact point 2a, electric current I flows by this contact point 2a.The electric current that this dotted line is represented is undesirable, and so far can only be by the in addition not enough inhibition of expansion separated part 3.
For having provided basically better according to bus duct 1 structure of the present invention that electric current suppresses shown in the current colector position a to d of Fig. 2.Bus duct 1 is divided once more in the stub area of its feed section 1.1 and 1.2.Be provided with an insulating segment 4 that bus duct interlude 5 is separated with the bus duct end segment 6 of feed section 1.1 or 1.2 for this reason.Insulating segment 4 each a free diode 7.1 or 7.2 cross-over connections wherein, be diode 7.1 with 7.2 negative electrode, for negative bus duct for positive bus duct are diodes 7.1 and 7.2 relative Face to face being positioned on the adjacent feed section 1.1 and 1.2 of anode.Shown is a positive bus duct.Obviously, not having electric current to pass through current colector 2 on the position a corresponding to the position a among Fig. 1 flows.This electric current is avoided owing to oppositely directed direction of current in the bus duct end segment 6 of feed section 1.1 and 1.2.
B finds out from the position, if current colector 2 by its contact point 2a and 2b cross-over connection diode circuit, then the part of electric current I flows by this current colector 2.
With reference to figure c as can be seen, the power supply trouble 8 of feed section 1.2 cause with according to the identical currentless situation of the normal function of a.
In corresponding to Fig. 1, on the position d of position b, there is not undesirable electric current to flow equally by the contact point 2a of current colector 2.
Fig. 3 shows the essential structure group of related bus architecture once more with schematic diagram, with and power supply by feed cable 9.
