Description
Technical field
The utility model relates to the railroad track of a kind of non-ferromagnetic conductive body combination.Be applicable to electrified field of track traffic.
Background technology
Track is one of major technique equipment of railway, is the basis of driving.Rail is the topmost component part of track structure, and the rolling for wheel provides continuous and the minimum contact surface of resistance.
Since the traffic of development electrified track, rail also carries the function as locomotive electrical power and electric current conduction.But the impedance caused because rail itself also exists larger ferrimagnetism, particularly to alternating current, the impedance that rail presents is comparatively large, causes power consumption larger.
CRH3 type motor train unit tractive output as 8 marshallings crosses 8800 kilowatts, and day bus hauling engine SS9 tractive output also has 4800KW.Calculate with the locomotive power of 8800KW, electric current is I=8800KW/25KV=352A, due in electrified railway, wherein a part of employing rail transferring electric power, with contact system power 25KV voltage calculate, the electric current flowing through rail is 352 amperes, reaches as high as Z=0.57 Ω/KM through surveying its comprehensive impedance.Because return wire is greater than 2 block sections, office's road circuit section overall length is pressed 4KM and is calculated, L=2KM, Z=2 × 0.57=1.14 Ω, the loss P=I that it is in operation
2× Z=350
2× 1.14 up to 140KW.If long-time running, electricity Q=Pt=140 × 6000 hour=840000 degree, namely the loss in a year of each train reaches 840,000 degree of electricity, and this is a no small loss.Improved by track circuit, the transmittability improving electric power is very necessary.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, provides the railroad track of simple, the lower-cost non-ferromagnetic conductive body combination of a kind of structure, to improve the usefulness of power transmission, Loss reducing.
The technical scheme that the utility model adopts is: a kind of railroad track of non-ferromagnetic conductive body combination, it is characterized in that: the electric connection assist in each embedding in web of the rail both sides one of irony track with excellent conductive performance, this attaching parts adopts non-ferromagnetic conductive material to make, electric connection assist is connected side by side with irony track, jointly forms circuit parallel.
The conductive material that described electric connection assist adopts metallic aluminium or its alloy, copper or its alloy to make.
Described electric connection assist is fixed on the web of the rail both sides of irony track by the body of bolt, and is aided with anti-loose structure.
Described electric connection assist is fixedly welded on the web of the rail both sides of irony track.
Described electric connection assist is fixed on the web of the rail both sides of irony track in casting mode.
Described electric connection assist skin is covered with anticorrosion, weather-proof coating of organic material.
Described organic coating is epoxy resin, anti-embroidery paint, polyurethane or polyureas.
The beneficial effects of the utility model are: original track improves by the utility model, at each embedding in web of the rail both sides electric connection assist of irony track, improve the usefulness of power transmission, Loss reducing, also be one to track signaling circuit well to advance, improve the transmission length of signal, the investment amount to track signalling set in railway construction can be greatly reduced.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Fig. 2 ~ Fig. 5 is the railroad track schematic diagram with polygon plate-like connecting member.
Detailed description of the invention
As shown in Figure 1, the present embodiment is the railroad track of a kind of non-ferromagnetic conductive body combination, the each embedding of the web of the rail two one of the irony track 1 in conventional railway track body has the electric connection assist 2 of good electric conductivity, material is the non-ferromagnetic conductive material (this example adopts aluminum strip) of metallic aluminium or its alloy, copper bar or its alloy body, electric connection assist 2 connects side by side in the both sides of irony track 1, jointly forms circuit parallel.
In this example, irony track 1 and electric connection assist 2 can be that casting mode is connected, weld or be fixedly connected with the body of bolt 3, and be aided with anti-loose structure (as flat gasket, spring washer, applying glue etc.), make irony track 1 as a whole with electric connection assist 2 one-tenth.
Electric connection assist 2 can be flat bar tabular (see Fig. 1) or press the polygon-shaped design electric conductor (see Fig. 2 ~ 5) with track I-shape medial concavity close contact.Electric connection assist 2 skin adopts anticorrosion, weather-proof organic coating to protect, and organic coating can be withstanding corrosion, the weather-proof inorganic or organic coatings such as epoxy resin, anti-embroidery paint, polyurethane, polyureas.
Stressed track in railroad track and electric tracks arrange by the present embodiment respectively, give full play to the difference in functionality of two tracks, also substantially increase safety simultaneously, after particularly employing electric connection assist 2 (being aluminum strip in this example), the high resistance over voltage caused because ferromagnetic impedance is large can be greatly reduced, and cause the harm to track circuit system voltge surge.
Although add aluminum strip can there is certain influence to the disconnected rail detection of track signaling circuit, but due to aluminum strip shearing strength value be less than rail, and irony track 1 and aluminum strip are linked to be entirety, general when track ruptures aluminum strip prior to rail break, with porous screw, rail and aluminium rail are fully compressed in the design, be conducive to the conformability of bearing shearing strength value like this.Meanwhile, due to the impact without ferromagnetic impedance, improve the usefulness of power transmission, Loss reducing, make the data in railway signal system can transmit farther distance.
