Description
Technical field
The present invention relates to urban public transport power supply technique field, more particularly to rapid transit system (BRT) is led
Draw power supply technique.
Background technology
Urban public transport is crowded to capacity and environmental pollution constantly deteriorates under ground serious stern form, electric propulsion traffic work
Tool becomes the first choice that city solves traffic problems with advantages such as its large conveying quantity, high efficiency, low stain, sustainabilities.
Two classes are broadly divided into using the urban public tranlport system of electric propulsion at present：Subway, the city that light rail is representative
Rail traffic and trolleybus.Urban track traffic generally uses direct-current traction power supply of the rated voltage for 750V or 1500V,
Advantage is that the Traction networks between traction substation are to connect hand in hand, constitutes through electric power system, and in similary voltage
It is smaller than the loss of voltage of AC system under grade, it is a kind of more competitive urban public transport form, the drawback is that underground
Stray electrical current causes electrochemical corrosion to metal pipe line along the line, serious to destroy civil engineering agent structure, metal shell and other
Lower metal pipe line, and corrode aggravation with the extension of service time, in addition, urban track traffic investment is big, the construction period is long, need
There is a fixed track, right of way is in the form of a single etc..For urban track traffic, trolleybus without stray current corrosion problem,
Have the characteristics that right of way diversification of forms, it is primary it is at low cost, operation maintenance is few, flexibly convenient, gradually favored and approved.So
And trolleybus need to set up overhead contact line in city public domain, not only influence city appearance, more important is employ
A pair of (double) contact line is flowed with a pair of (double) trolley pole (being commonly called as plait), considerably increases the complexity of contact net, to design,
Operation and maintenance bring larger difficulty, particularly at crossing, it has to and interruption of power supply forms non-Electric region, once therefore stop, it will
Influence operation.
The present invention proposes a kind of road surface power-supply construction, compact-sized, operation is convenient, safe and reliable, economical and practical, also has
Right of way form is relatively free, does not influence the features such as urban landscape, is a kind of effective scheme for solving urban public tranlport system,
It powers particularly suitable for rapid transit system (BRT).
Invention content
The object of the present invention is to provide a kind of road surface power-supply constructions of rapid transit system, it can efficiently solve and lead
Draw stray electrical current existing for electric power and step voltage may be to pedestrains safety protection problem.
The present invention is realizes its purpose, using following technical scheme：A kind of road surface power-supply structure of rapid transit system
It makes, car body, driving mechanism and road surface including vehicle, direct route face extending direction continuous laying is by power supply slot, backflash, insulation bottom
The power supply band that seat and insulating shield are formed；The top of insulator foot be equipped with insulating shield, the upper surface of insulator foot both sides and absolutely
Power supply gap and reflux gap are respectively formed between the lower surface of edge shield both sides, the top laying power supply slot in the gap that powers returns
Flow the top laying backflash in gap；Carbody is hinged on for electric pole and reflux bar by insulating ferrule respectively to drive close to vehicle
It on the chassis of motivation structure, and is rolled over upward lower section is at an acute angle, is respectively protruding into power supply gap and reflux gap；For the head end of electric pole
It connect with one end of drive mechanism for vehicle input port, is contacted for electric pole end with power supply slot；Flow back the head end of bar and vehicle drive
The other end connection of motivation structure input port, the end for the bar that flows back is contacted with backflash；Through slot of powering, for electric pole, vehicle traction
Mechanism, reflux bar, backflash form current supply circuit.
It is described that insulated hull is surrounded by addition to end for electric pole and reflux bar, enhance anti-flooding and short-circuit energy caused by water logging
Power.
It is described power supply gap and reflux gap have narrow and deep shape, ensure hand cannot stretch into gap or touch less than
Power supply slot, backflash, eliminate the possibility manually got an electric shock.
Vehicle both sides wheel in road traveling is ridden in power supply band.Lateral trench is equipped with below insulator foot, so as to
Rainwater circulates, and avoids or reduces ponding；Insulator foot plus insulating shield overall height general control in 200mm hereinafter, with
Just it is walked when rapid transit system vehicle emergency is detached from circuit, also section is being allowed to be walked convenient for pedestrian, when necessary
Other vehicles can also walk.Obviously, it is desirable that the depth of accumulated water (national regulations≤150mm) for running satisfaction is deeper, insulator foot
Height is higher.Insulator foot and insulating shield have certain intensity, i.e., certain rigidity and plasticity usually select fiberglass
It is advisable.The rigidity of insulator foot should be enough to support power supply slot and backflash and from being rubbed therewith for electric pole and reflux bar
Pressure；Insulating shield also has certain intensity, can bear vehicle rolling once in a while.Utilize the modeling of insulator foot and insulating shield
Property, power slot and backflash can be embedded in the engaging portion of insulator foot and insulating shield.Insulating ferrule only plays insulating effect, can
Select the manufactured goods of the materials such as general rubber, resin.
The present invention operation principle be：The rigidity and plasticity that insulator foot and insulating shield are had and power rail and reflux
The mounting structure of rail is combined, and in existing space, constructs a kind of most compact, simplest independence for electrically isolating from rail and railway roadbed
Current supply circuit.The dielectric coefficient of insulator foot and insulating shield material is high, when using power frequency power supply, can greatly enhance confession
The power supply capacity of electrical circuit.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention mutually insulate with road surface, forms independent traction power supply circuit, does not generate stray electrical current and ground strides
Voltage can also avoid the danger manually got an electric shock, the protection person and installation security.
2nd, the present invention can effectively avoid short trouble, improve power supply reliability.
3rd, the present invention is installed on the road surface of rapid transit system, does not influence other roads and facility, and at low cost,
Construction and installation amount is few, good economy performance.
4th, the present invention will not cause harmful effect to urban landscape.
5th, the dielectric constant of insulator foot and insulating shield material of the present invention is high, can be significantly when using power frequency power supply
Enhance the power supply capacity of current supply circuit.
6th, the compact-sized, simple installation of the present invention, easy to maintain, securely and reliably, service life is long, i.e., is built suitable for new line
If it is also applied for Existing railway promotion.
