Description
Technical field
This utility model relates to urban public transport power supply technique field, particularly to the traction of rapid transit system (BRT)
Power supply technique.
Background technology
And environmental pollution crowded to capacity in urban public transport constantly deteriorates under ground serious stern form, and the electric propulsion vehicles are with it
The advantages such as large conveying quantity, high efficiency, low stain, sustainability, become city and solve the first-selection of traffic problems.
The urban public tranlport system of electric propulsion is used to be broadly divided into two classes at present: subway, light rail are that the city rail of representative is handed over
Lead to and trolleybus.The commonly used rated voltage of urban track traffic is the direct-current traction power supply of 750V or 1500V, and its advantage exists
Traction networks between traction substation is to connect hand in hand, constitutes through electric power system, and compares under same electric pressure
The loss of voltage of AC system is little, is a kind of more competitive urban public transport form, and its shortcoming is the stray electrical current pair of underground
Metal pipe line along the line causes electrochemical corrosion, heavy damage civil engineering agent structure, metal shell and other underground metal pipeline,
And along with aggravation is corroded in the prolongation of service time, it addition, urban track traffic investment is big, the construction period is long, need to have fixing rail
Road, right of way form is single.For comparing urban track traffic, trolleybus, without stray current corrosion problem, has right of way shape
Formula variation, low cost, an operation maintenance feature the most easily few, flexible, gradually favored and approved.But, trackless
Electric car need to set up overhead contact line in public territory, city, not only affects city look and feel, more importantly, have employed a pair (double)
Contact line and a pair (double) trolley pole (being commonly called as plait) are flowed, and considerably increase the complexity of contact net, give design, run
Bring bigger difficulty with maintenance, particularly at crossing, it has to interruption of power supply, form non-Electric region, the most therefore stop, by shadow
Ring and run.
The utility model proposes a kind of road surface power-supply structure, compact conformation, run convenient, safe and reliable, economical and practical, also have
There is right of way form the most freely, not affect the features such as urban look, be a kind of effective scheme solving urban public tranlport system,
It is particularly suitable for rapid transit system (BRT) power supply.

High.Insulator foot and insulating shield have certain intensity, the most certain rigidity and plasticity, generally select fiberglass to be advisable.Absolutely
The rigidity of edge base should be enough to support power supply groove and backflash and from the pressure for electric pole with backflow bar rubbed therewith；Insulation
Guard shield also has certain intensity, can bear vehicle rolling once in a while.Utilize the plasticity of insulator foot and insulating shield, groove of powering
With the joint portion that backflash can be embedded in insulator foot and insulating shield.Insulating ferrule only plays insulating effect, can be selected for general
The manufactured goods of the material such as rubber, resin.
Operation principle of the present utility model is: rigidity insulator foot and insulating shield being had and plasticity and power rail and return current rail
Mounting structure combine, in existing space, construct and a kind of the compactest, simplest electrically isolate from the independent of rail and railway roadbed
Current supply circuit.The dielectric coefficient of insulator foot and insulating shield material is high, when using power frequency to power, can be greatly enhanced power supply
The power supply capacity in loop.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model insulate mutually with road surface, forms independent traction power supply loop, does not produce stray electrical current and ground step voltage,
Also the danger of free-hand electric shock, the protection person and installation security can be avoided.
