Description
Technical field
It is especially a kind of to be based on non-track circuit pattern the present invention relates to the wiring technique field of metro traction power system
Novel subway traction power supply linear system system rolling stock section's cable and rail wiring new method.
Background technology
At present in metro traction power system, generally using rail return current pattern, typical metro traction power system car
Schematic diagram is as shown in Fig. 1 metro depot tractive power supply system schematic diagrames in section.
Current path is:Traction substation positive pole → feed line → contact net → vehicle (load) → rail → return wire →
Traction substation negative pole.The connection of wherein rail and return wire be ensure the important step reliably runed of tractive power supply system it
One.Simultaneously in order to reduce return cable connection as far as possible to influence caused by rail, it should try one's best and reduce the tie point of cable and rail.
Existing return cable has differences from rail connection scheme according to the different of signal mode.Signal in rolling stock section
Pattern can be divided into track circuit pattern and non-track circuit pattern.When signal uses track circuit, in two one steel rails per station track
A transmission circuit as signal, return cable do not allow to connect；And when using non-track circuit, two steel per station track
Rail return cable can connect.
1st, prior art scenario：
Subway return wire is generally made up of two types cable at present, wherein the return cable being connected with rail uses section
The less flexible cable of product, and the return cable of traction substation negative pole is connected to using sectional area is larger, hard cable of matcoveredn,
Transition and conversion is carried out by " return tank " between the two.
When signal uses the pattern based on non-track circuit, the specific connection plan of rolling stock section is：If from return tank to
The total radical of flexible cable of rail is N (usual N is 8~10), N root flexible cables is drawn from return tank first, by N/2 roots therein
Flexible cable, which is connected to every station track two, can connect one in rail, and remaining N/2 root flexible cable, which is connected to other one, can connect steel
Rail.Then the series connection of N/2 roots flexible cable is connected into next station track again one can connect rail, and remaining N/2 root flexible cable is connected to separately
Outer one can connect rail, by that analogy.Schematic diagram is as shown in Figure 2.
2nd, the technical problem that need to be solved：
As shown in Fig. 2 return cable, which is connected existing scheme with rail, disclosure satisfy that tractive power supply system in metro depot
Demand, but following technical problem be present：
(1) tie point of cable and rail is more, and construction and operation maintenance workload are big.As shown in Fig. 2 per station track cable
Amounting to rail tie point has 2N (4*N/2).According further to metro depot tractive power supply system characteristic, per track outside storehouse
With in storehouse between set isolated rail joint, insulation joint both sides set return cable connection respectively, and both sides return cable passes through a kind of unidirectional
Conducting device connects, as shown in Figure 3.Therefore, the tie point of every station track cable and rail is 4N.With the vehicle of 20 station tracks
Exemplified by section, when return cable radical is 10, tie point is up to 800 (2* (4*10/2) * 20) before storehouse.
(2) in addition to the track close to return tank, the return current path of other station tracks increases by rail switching link
Potential faults points.
3rd, reason of problems：It is that return cable and rail connection scheme are unreasonable, return cable is transferred by rail
It is back to return tank.
The content of the invention
It is an object of the invention to overcome above-mentioned return cable of the prior art and rail connection scheme unreasonable, backflow
The problem of cable is back to return tank by rail switching, on the basis of current subway return wire design fundamentals are not changed, lead to
Cross and set the method for return tank to reduce the tie point of cable and rail between station track, there is provided one kind is based on non-track circuit pattern
Rolling stock section's return cable and rail mode of connection, avoid cable from passing through unfavorable factor caused by rail.
In order to achieve the above object, the present invention adopts the following technical scheme that：A kind of vehicle based on non-track circuit pattern
Section return cable and rail wiring new method, specific method are as follows：
(1) main return cable is set in station track 1 and station track N outside, and between the stock between the N of station track 1 to station track all
Set up the return tank of auxiliary；
(2) the flexible cable connection radical between return tank is N；
(3) drawn from return tank 3 (or 2, specific radical is chosen according to engineering is actual) flexible cables are connected to
Connecting on rail on the preceding station track of adjacent side；
(3) drawn from return tank 3 (or 2, specific radical is chosen according to engineering is actual) flexible cables are connected to
Connecting on rail on the rear station track of adjacent side.
Main return cable in the step (1) is transferred by return tank；
The flexible cable for connecting rail being connected in the step (3) on the preceding station track of adjacent side is drawn from return tank
's；
The flexible cable for connecting rail being connected in the step (4) on the rear station track of adjacent side is drawn from return tank
's.
Compared with prior art, the beneficial effect that the present invention reaches：
1st, present invention employs the scheme for setting up return tank switching, the connection of cable and rail is on the one hand greatly reduced
Point, cable is on the other hand avoided by being adversely affected caused by rail switching, equally with the railcar of 20 station tracks
Exemplified by section engineering, by new arrangement scheme, it is assumed that the total radical N of return cable is 10, connects the every flexible cable that can connect rail
Radical is 3, then return cable adds up to rail tie point before New Scheme storehouse：At 2* (2*3) * 20=240, tie point subtracts
Few 70%.
2nd, the present invention is greatly reduced cable and rail tie point, avoids cable from being transferred through rail by setting up return tank,
Construction and installation and operation maintenance cost are not only reduced, also improves the reliability of return flow path, there are higher popularization and application
Value, can be applied in China subway field.
