Description
Technical field
The present invention refers to a kind of short rail formula electricity segmental structure that can take into account near, at a specified future date vehicle marshalling especially about a kind of urban track traffic and inter-city rail transit tractive power supply system.
Background technology
What early stage subway adopted is that disconnected gauge is from the broken rail electricity segmentation for 14m, must be arranged in the preceding coasting district of vehicle pull-in, for being the vehicle of independent traction unit with the single-unit motor-car, vehicle does not in early days generally possess under the situation of regenerative brake function, vehicle does not generally have very big electric arc during the electric segmentation by the disconnected rail of 14m yet after the coasting section traction electric machine that enters the station stops to get stream, can satisfy the operation requirement substantially, but room light can be subjected to temporary influence.
Vehicle generally all has the regenerative brake function now, if continue to continue to use the segmentation of broken rail electricity, and the disconnected gauge that the segmentation of broken rail electricity is set is from the pantagraph current collector spacing greater than a traction unit of vehicle, no matter then vehicle is to get the stream operation or at the electric braking state, all may produce big electric arc, scaling loss contact rail and pantagraph current collector slide plate, under frequent powering-off state, appliance life shortens in the car, and maintenance capacity increases, and causes operating cost to increase.And if the disconnected gauge of broken rail electricity segmentation is from the pantagraph current collector spacing less than a traction unit of vehicle, then might suddenly power outage appear and when having little time to avoid vehicle to swarm into the dead electricity district in a power supply zone, be communicated with electric subregion in bad order and failure-free adjacent electric subregion, not only enlarge the accident incidence, and may bring greater loss in some cases.
And the short rail formula electricity segmentation of adopting has at present taken into account above-mentioned various aspects preferably; but must pay special attention to the reasonableness that short rail arranges the position; if it is improper to arrange; bigger sudden change may occur at vehicle launch period of acceleration feeder current and cause the fender guard misoperation, also still have electric arc between pantagraph current collector and contact rail and occur.At present short rail formula electricity segmentation arrangement form has following two schemes:
Scheme one: will lack rail at the traction substation place and be arranged in the vehicle pull-in end, the contact rail in short rail and vehicle operating the place ahead is powered by same feeder line, short rail length is by vehicle towed element length setting, when vehicle starts in the station, all pantagraph current collectors are all got stream from the same feeding section of train working direction, do not have the feeding section transfer problem in being advanced to the power supply of same traction unit and train by two different feeder lines, each traction unit has that higher to get stream stable.But the shortcoming of this scheme is must adjust short rail position when near, at a specified future date vehicle marshalling is adjusted.
Scheme two: short rail length arranges by full vehicle commander's degree, and the electrical wiring mode is identical with scheme one, but the discharge capacity of lacking DC contactor on the rail feed pathway need increase be twice above.The advantage of scheme two is needn't adjust short rail position when near, at a specified future date vehicle marshalling is adjusted, and shortcoming is that the high-capacity direct current contactless switch needs import, and price is high; May make vehicle lose kinetic energy in standing during when DC contactor and with cable et out of order that short rail links to each other, and then cause backlog.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of short rail formula electricity segmental structure that can take into account near, at a specified future date vehicle marshalling and avoid backlog.
For achieving the above object, the invention provides a kind of short rail formula electricity segmental structure, it comprises in the platform section on the side joint rail-engaging the isolated first corresponding short rail and the second weak point rail on the isolated first short rail and the second short rail and opposite side contact rail, wherein each first short rail is powered by first DC contactor, each second short rail is powered by second DC contactor, do not have between the short rail of on each side joint rail-engaging first and the second short rail and be electrically connected, the contact rail part of lacking the rail except the first short rail and second on each side joint rail-engaging is connected to different substations by cable separately, and each substation is connected to first DC contactor and second DC contactor that connects on this side joint rail-engaging by cable.
Wherein be connected with disconnector between second DC contactor of a side joint rail-engaging and the substation that is connected, be connected with another disconnector between first DC contactor of opposite side contact rail and the substation that is connected.
The described first short rail on each side joint rail-engaging equates with the train total length with the second short rail length overall.
The described first short rail and the second short rail on each side joint rail-engaging independently arrange separately.
The short rail formula electricity of the present invention segmental structure can keep uninterrupted power supply to vehicle when normal operation, owing to adopt two sections short rails (the first short rail, the second short rail), compare with the existing scheme that one section short rail only is set, not because the conduction of train internal circuit causes adjacent power supply zone electrical accident also to occur, can better take into account near, at a specified future date vehicle marshalling simultaneously in the time of can avoiding in a power supply zone, electrical accident occurring.In addition, because the present invention adopts two DC contactor, compare with the existing scheme that a DC contactor only is set, can avoid adopting high-capacity DC contactor, economic benefit is more excellent.
