Abstract
The invention relates to the technical field of wiring a vehicle depot of a metro traction power supply system and particularly relates to a novel vehicle depot reflowing cable and steel rail wiring method based on a track circuit mode. The novel vehicle depot reflowing cable and steel rail wiring method is characterized in that the specific wiring method comprises the following steps: (1) arranging main reflowing cables on the outer sides of a station track I and a station track N, and additionally arranging auxiliary reflowing boxes between every two tracks from the station track I to the station track N; (2) connecting N soft cables between the reflowing boxes; and (3) connecting the three soft cables (or two soft cables, wherein the quantity is selected according to practical engineering conditions) led out from the reflowing boxes to a connectable steel rail on the adjacent side. By additionally arranging the reflowing boxes, connection points of the cables and the steel rail are greatly reduced, and the cables are prevented from adapter coupling through the steel rail, so that the construction and installation cost and the operation and maintenance cost are reduced, and the reliability of a reflowing path is also improved; and the novel vehicle depot reflowing cable and steel rail wiring method based on the track circuit mode has relatively high popularization and application values, and can be applied to the field of metros in China.
Description
Technical field
The present invention relates to the wiring technique field of metro traction power system, especially a kind of novel subway traction power supply wire system rolling stock section's backflow cable based on track circuit-mode and rail wiring novel method.
Background technology
In current metro traction power system, generally adopting rail return current pattern, in typical metro traction power system rolling stock section, schematic diagram is as shown in Fig. 1 metro depot traction power supply system schematic.
Electric current path is: traction electric substation positive pole → feeder line → contact system → vehicle (load) → rail → return wire → traction electric substation negative pole. Wherein the connection of rail and return wire ensures one of important step of reliably runing of traction power supply system. Connect the impact that rail produces to reduce backflow cable as far as possible simultaneously, the tie point of cable and rail should be reduced as far as possible.
Difference is there is according to the different of signal mode in existing backflow cable from rail connection scheme. In rolling stock section, signal mode can be divided into track circuit-mode and non-track circuit-mode. During signal employing track circuit, a transmission circuit as signal in two one steel rails of every station track, backflow cable does not allow to connect; And when adopting non-track circuit, two one steel rails backflow cables of every station track all can connect.
1, prior art scenario:
Current subway return wire is made up of two type cables usually; the flexible cable that the backflow cable being wherein connected with rail adopts sectional area less; and the backflow cable being connected to traction electric substation negative pole adopt sectional area relatively big, have the hard cable of protective layer, carry out transition and conversion by " return tank " between the two.
When signal adopts the pattern based on track circuit, the concrete connection plan of rolling stock section is: set the total radical of flexible cable from return tank to rail as N (usual N is 8～10), first N root flexible cable is drawn from return tank, it is connected to the connected rail of the contiguous station track of return tank, and then adopt N root flexible cable series connection to the connected rail of another station track, analogize with this. Schematic diagram is as shown in Figure 2.
2, the technical problem that need to solve:
As shown in Figure 2, backflow cable is connected the demand that existing scheme can meet traction power supply system in metro depot with rail, but there is following technical problem:
(1) tie point of cable and rail is more, and construction and operation maintenance workload are big. As shown in Figure 2, every station track cable and rail tie point have 2N (N+N) altogether. In addition according to metro depot traction power supply system characteristic, every track outside storehouse and in storehouse between establish isolated rail joint, insulation joint both sides establish backflow cable to connect respectively, and two side reflux cables are connected by a kind of device in one-way on state, as shown in Figure 3. Therefore, the tie point of every station track cable and rail is 4N.
For the rolling stock section of 20 station tracks, when the cable radical that refluxes is 10, before storehouse, tie point will reach 800 (2* (10+10) * 20).
(2) except, except the track of return tank, the back flow current path of other station track all through rail switching link, increases potential faults point.
3, the reason of existing problems: being that backflow cable and rail connection scheme are unreasonable, backflow cable is back to return tank by rail switching.
Summary of the invention
It is an object of the invention to overcome above-mentioned backflow cable of the prior art and rail connection scheme unreasonable, backflow cable is back to the problem of return tank by rail switching, do not changing on current subway return wire design fundamentals basis, the tie point of cable and rail is reduced by arranging the method for return tank between station track, a kind of rolling stock section based on track circuit-mode backflow cable and rail wiring novel method are provided, avoid the unfavorable factor that cable is produced by rail.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of rolling stock section based on track circuit-mode backflow cable and rail wiring novel method, and concrete grammar is as follows:
(1) at the main backflow cable of the arranged outside of station track 1 and station track N, and auxiliary return tank is set up between stock between 1 to the N of station track;
(2) flexible cable between return tank connects radical is N;
(3) 3 (or 2, concrete radical is chosen according to engineering the is actual) flexible cables drawn from return tank are connected on the connected rail of adjacent side.
Main backflow cable in described step (1) is transferred by return tank;
The flexible cable of the connected rail being connected to adjacent side in described step (3) is drawn from return tank.
Compared with prior art, the useful effect that the present invention reaches:
1, present invention employs the scheme setting up return tank switching, significantly reduce the tie point of cable and rail on the one hand, avoid the disadvantageous effect that cable is transferred by rail and produced on the other hand. Same for the metro depot engineering of 20 station tracks, by new arrangement scheme, assuming that the backflow total radical N of cable is 10, connecting the flexible cable radical that every root can connect rail is 3, then before New Scheme storehouse, backflow cable and rail tie point total are: 2*3*20=120 place, tie point reduces 85%.
2, the present invention is by setting up return tank, significantly reduces cable and rail tie point, avoids cable to transfer through rail, not only reduce construction and installation and operation maintenance cost, also improve the reliability of return flow path, there is higher application value, can apply in China's subway field.
