Description
Technical field
The present invention relates to the wiring technique field of metro traction power system, especially a kind of based on non-track circuit
Novel subway traction power supply wire system rolling stock section's cable of pattern and rail wiring new method.
Background technology
At present in metro traction power system, commonly used rail return current pattern, typical subway traction power supply system
In system rolling stock section, schematic diagram is as shown in Fig. 1 metro depot tractive power supply system schematic diagram.
Current path is: traction substation positive pole → feed line → contact net → vehicle (load) → rail → return
Streamline → traction substation negative pole.Wherein with the connection of return wire, rail is to ensure that tractive power supply system is reliably transported
One of important step of battalion.The impact simultaneously produced rail to reduce return cable to connect as far as possible, should use up
Amount reduces the junction point of cable and rail.
Existing return cable there are differences according to the different of signal mode from rail connection scheme.Rolling stock section
Interior signal mode can be divided into track circuit pattern and non-track circuit pattern.When signal uses track circuit, often
A transmission circuit as signal in two one steel rails of station track, return cable does not allow to connect；And use
During non-track circuit, two one steel rail return cables of every station track all can connect.
1, prior art scenario:
Subway return wire is generally made up of two types cable at present, and the return cable being wherein connected with rail is adopted
With the less flexible cable of sectional area, and the return cable being connected to traction substation negative pole use sectional area relatively big,
The hard cable of matcoveredn, carries out transition and conversion by " return tank " between the two.
When signal uses pattern based on non-track circuit, the concrete connection plan of rolling stock section is: set from returning
Stream case is N (usual N is 8～10) to the total radical of flexible cable of rail, first draws the soft electricity of N root from return tank
Cable, N/2 root flexible cable therein is connected to that two, every station track can connect in rail one, remaining N/2 root
Flexible cable is connected to other one can connect rail.The most again the series connection of N/2 root flexible cable is connected to the one of next station track
Root can connect rail, and remaining N/2 root flexible cable is connected to other one can connect rail, by that analogy.Schematic diagram
As shown in Figure 2.
2, need to solve the technical problem that:
As in figure 2 it is shown, return cable is connected existing scheme with rail disclosure satisfy that tractive power supply system in metro depot
Demand, but there is following technical problem:
(1) cable is more with the junction point of rail, and construction and operation maintenance workload are big.As in figure 2 it is shown, it is per share
Road cable and rail junction point have 2N (4*N/2) altogether.According further to metro depot tractive power supply system
Characteristic, every track outside storehouse and in storehouse between set isolated rail joint, insulation joint both sides set return cable even respectively
Connecing, both sides return cable is connected, as shown in Figure 3 by a kind of device in one-way on state.Therefore, every station track cable
It it is 4N with the junction point of rail.As a example by the rolling stock section of 20 station tracks, when return cable radical is 10
Time, before storehouse, junction point is up to 800 (2* (4*10/2) * 20).
(2) except near return tank track in addition to, the return current path of other station track all through rail transfer link,
Increase potential faults point.
3, in-problem reason: being that return cable is unreasonable with rail connection scheme, return cable is turned by rail
Take back to return tank.
Summary of the invention
It is an object of the invention to overcome above-mentioned return cable of the prior art unreasonable with rail connection scheme,
Return cable is back to the problem of return tank by rail switching, is not changing current subway return wire Basic Design
On basis, reduced the junction point of cable and rail by the method arranging return tank between station track, carry
For a kind of rolling stock section's return cable based on non-track circuit pattern and rail mode of connection, it is to avoid cable passes through
Unfavorable factor produced by rail.
In order to achieve the above object, the present invention adopts the following technical scheme that a kind of based on non-track circuit pattern
Rolling stock section's return cable and rail wiring new method, concrete grammar is as follows:
(1) outside in station track 1 and station track N arranges main return cable, and the stock between the N of 1 to station track, station track
Between all set up the return tank of auxiliary；
(2) flexible cable between return tank connects radical is N；
(3) 3 (or 2, concrete radical is chosen according to engineering is actual) flexible cables will drawn from return tank
It is connected on the connected rail on the front station track of adjacent side；
(3) by 3 (or 2, concrete radical is chosen according to engineering is actual) flexible cables drawing from return tank even
It is connected on the connected rail on the rear station track of adjacent side.
Main return cable in described step (1) is to be transferred by return tank；
The flexible cable being connected to the connected rail on the front station track of adjacent side in described step (3) is from backflow
Case is drawn；
The flexible cable being connected to the connected rail on the rear station track of adjacent side in described step (4) is from backflow
Case is drawn.
Compared with prior art, the beneficial effect that the present invention reaches:
1, present invention employs the scheme that return tank is transferred of setting up, one side is greatly reduced the connection of cable and rail
Point, on the other hand avoids cable and passes through the produced adverse effect of rail switching, equally with 20 station tracks
Metro depot engineering as a example by, by new arrangement scheme, it is assumed that return cable total radical N is 10, connect every
It is 3 that root can connect the flexible cable radical of rail, then before New Scheme storehouse, return cable amounts to rail junction point
For: at 2* (2*3) * 20=240, junction point reduces 70%.
2, the present invention is by setting up return tank, cable and rail junction point is greatly reduced, it is to avoid cable turns through rail
Connect, not only reduce construction and installation and operation maintenance cost, also improve the reliability of return flow path, have
Higher application value, can apply in China's subway field.
