Abstract
It is an object of the present invention to by a kind of simple designs, realize that the electric power-feeding structure bottom of tramcar is installed, realize that electric power supply system is installed on ground.It is the improvement to current tramcar " the 3rd rail " electric power system, improvement the invention provides a kind of design structure that subway, high speed motor car service cable are changed into road surfacing.
Description
Technical field：
It is to current rail the invention provides a kind of design structure that subway, high speed motor car service cable are changed into road surfacing
The improvement, improvement of electric car " the 3rd rail " electric power system.
Background technology：
On the occasion of the period of China's rapid economic development, in order to meet the transport power demand that China is growing, China has formulated railway
Electrified middle long plan, newly-built electric railway, old circuit electrification innovation enormous amount.Electrified line newly-built at present
Road has been required for overhead route --- and i.e. by train power supply cable suspension in aerial, this powered construction, which needs to consume flood tide steel, to be made
For wire rack.
The present invention with regard to bullet train service cable be changed into earth's surface laying possibility entered a kind of An attempt of design, although not into
Ripe, also imperfection, but if being designed to come true, it will the huge economic benefit of creation, benefits the society.
The content of the invention：
（1）Purpose：It is an object of the present invention to by a kind of simple designs, realize that the electric power-feeding structure bottom of tramcar is installed,
Realize that electric power supply system is installed on ground.
（2）Technical scheme：By the supporting construction for the service cable that tramcar is laid on ground, realize that tramcar is supplied
Electrical cables change into ground installation from current aerial erection.
Structure be open-topped tubular structure, outer wall insulation, service cable be suspended in wherein, by tramcar,
Miniature " bow collector " that iron etc. is installed on vehicle bottom is tramcar, subway power supply.
Tubular structure be installed on sleeper or special pedestal on, parallel to track.In order to prevent interior accumulation dust etc.
Rubbish, makes cleaning relatively simple, easily causes accident potential.In its bottom design engraved structure, not ponding, and can use and blow
Blower fan etc. is cleared up, and natural rain drop erosion can also play cleaning action.
（3）Beneficial effect：
Subway, EMU service cable be changed into the laying of land face had compared with former overhead route it is obvious economical excellent
Gesture, it can probably be attributed to：
Save the infrastructure raw material such as great deal of steel.
Rough estimation, overhead line bracket, high line bracket 30 meter one, 30,000 public affairs are set up by current electric train along road one side
In electric railway need 1,000,000, support, by each 100 kilograms of support, it is necessary to 100,000 tons of steel, meanwhile, be related to Steel Structure
The supporting, protective materials such as installation, the cement of protection, paint also can be considerable quantity.Can so speed car be set to power
The overall construction cost of system is substantially reduced.
Save a large amount of electric energy.
Cable electric heating calculation formula：Q=U2t/R, but because resistance R is inversely proportional with cable thickness, overhead route is because of own wt
So that cable is slightly limited, electric energy utilization rate is extremely low, it is assumed that by thicker 3 times of " landing " copper conductor, only this or original waste can be made
Electric energy reduce to 1/3, resistance R is directly proportional to cable length, segmentation carry out supply of electric power can also save a large amount of electric energy.
Laying cost is low, and maintenance cost is low.
Install, set up the substantial amounts of manpower of the overhead line bracket needs of high speed motor car service cable, and corresponding transport, lifting
Equipment, will also be selected in express zone such as mountain area, deserts（Or build）Suitable ground.Ground laying type design is changed to, will
The installation of bullet train electric power system, construction cost are substantially reduced, a large amount of human and material resources, fund is saved.Although relative to frame
Various situations in the air, damage of the road surfacing to cable is bigger, but new departure is easy to maintenance, changes simple, maintenance because rain,
Snow, and the damage cost of supply line that the disaster such as mud-rock flow, earthquake is caused will also be substantially reduced.
（4）Brief description of the drawings：
Fig. 1 is the road surface power-supplies such as current high ferro " collector shoe " structural representation.
Fig. 2 is " collector shoe " along cable connection cross-sectional view
Fig. 3 is that the present invention one applies cross-sectional view
Fig. 4 is that the present invention one applies schematic top plan view.
（5）Embodiment：
Current floor power supply device structure is collector shoe.Collector shoe is installed on the outside of rail, and its " cable " is not original circle
Cylindricality, wire cable, but have the exposed square lead bar of one side.Even electric extension bar 7, by contact 6 and cable connection, receives confession
Electricity.
A kind of tramcar roadbed electric power-feeding structure of the present invention, is substantially also cable support protection structure, cable support thing
Parallel to track for a train, two rail centers are laid on.Pedestal 4 can be laid on railway sleeper beam 10.Total is built
If the laying of rail 11 can be similar to, grassroot project can together construct with rail 11.Total, such as protecting cover 1
Deng, need insulation, it is sturdy and durable.
Cable 5 " fixation " is on insulating base 3.The height of insulating base 3 causes cable 5 suitable away from ground level, protective cover
Body 1 can part rain and snow, people or animal false touch are prevented by it, leaking hole 2 can prevent that water, dust, winged insect, rubbish etc. are miscellaneous
The accumulation of thing.
Train design will also do corresponding change.New departure requires that bullet train needs to lean out even electric extension bar 7 by underbody,
It is connected by conductive cable contacts body 9 with service cable.
Connect electric extension bar 7, bow collector bow body 8, conductive cable contacts body 9 is collectively constituted miniature " bow collector ".Cable 5 can be segmented
Power supply, if subway, speed car carry stand-by power, in the case where part circuit is powered off, locomotive still can normally be run.
For turnout, the cable separated by rail can be connected by buried cable.System should have short circuit, power-off protection dress
Put, each section install monitoring device can at any time monitoring voltage, road conditions situations such as, in the hope of the situation that most notes abnormalities soon, in time
Repaired, prevent power-off, the appearance of power-off condition for a long time.
Claims (3)
