Abstract
The utility model discloses a double-contact-rail power supply device for rail transit. Contact rails are arranged on left and right sides of a rolling stock running rail, a power supply is arranged on one side, and a backflow rail is arranged on the other side. During running of a train, collector shoes on two sides of a rolling stock move with the contact rails on the same side in a contacting mode, and the collector shoes are connected with the rolling stock through insulating supports. The left-side contact rail (powder supply rail) and the left-side collector shoe, a main circuit of the rolling stock, the right-side collector shoe and the right-side contact rail (backflow rail) form a traction power supply loop. The collector shoes can be replaced by collector wheels, so that abrasion can be reduced, and the service life of equipment can be prolonged. The double-contact-rail power supply device is an independent loop which is insulated from the running rail and the ground and used for supplying power for the rolling stock main circuit, and stray currents and long-term corrosion effects can be eliminated fundamentally. The double-contact-rail power supply device is convenient to install, does not affect city appearances and can be applied to transformation of existing rail transit lines as well as newly-built rail transit lines.
Description
Technical field
The utility model relates to the two contact rail electric power systems of a kind of track traffic.
Background technology
Existing electrified railway and urban track traffic tractive power supply system all utilize rail as the traction current system, because rail not exclusively electrically isolates from the earth, therefore, traction current will be revealed to the earth and other objects through rail, produce stray current, be commonly called as fan's stream.Particularly DC traction is adopted in urban track traffic, the stray current that it produces all will produce electrochemical corrosion to bar construction in railway roadbed bar construction, the tunnel and facilities such as metal pipe line along the line, thereby influence safety and the service life of these structures and metallic facility.In addition, owing to adopt rail to reflux, it might form step voltage to the difference of potential that ground produces, and threatens personal safety.
The corrosion guard measure of existing stray current mainly contains the electrical drainage protection method, the outer Tu Fa of resistance method, stray current collecting method and pipeline etc. falls in rail, very big fund input all will be arranged, and can not fundamentally eliminate stray current and long-term corrosion influence thereof.
Therefore, the two contact rail electric power systems of track traffic, adopt two contact rails of power rail and backflow rail formation and the rail insulation of rolling stock to come, forming independently rolling stock traction power supply loop, is to eliminate rail and the earth step voltage, guarantee personal safety and eliminate stray current and the essential measure of long-term corrosion influence.
The utility model content
The purpose of this utility model: provide a kind of track traffic two contact rail electric power systems, this system separates the rail of rolling stock with current supply circuit, adopt two contact rails to form independently-powered loop, fundamentally eliminate the influence of stray current and long-term corrosion thereof, eliminate the step voltage of rail and the earth simultaneously, guarantee personal safety.
The utility model is for realizing its purpose, by the following technical solutions: the two contact rail electric supply installations of a kind of track traffic: in the left and right sides of rolling stock rail left side contact rail and right side contact rail are set respectively, this two contact rail is served as power rail and backflow rail respectively; Rolling stock corresponding position both sides are installed left side shoegear and right side shoegear respectively, and the left side shoegear supports and is connected with the rolling stock bogie truck by left side insulation support, right side insulation respectively with the right side shoegear; Left side shoegear and right side shoegear are respectively with locomotive vehicle contact movement on left side contact rail and right side contact rail; Left side contact rail and right side contact rail mutually insulated and ground insulation; Left side contact rail and left side shoegear, rolling stock power circuit, right side shoegear and right side contact rail constitute the traction power supply loop.
Further, shoegear can be changed to being subjected to the electricity wheel, at this moment, the power supply of rolling stock is to finish with the moving contact that contact by rolling between the electricity wheel and to be subjected to electricity to take turns both sides spindle nose and side pressure carbon brush by contact rail, the contact that realizes rolling is main, cliding friction is auxilliary, thereby significantly reduces abrasion, strengthens to be subjected to electrical stability and service life of equipment.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model adopts the rail insulation of two contact rails and rolling stock to come, and forms independently rolling stock traction power supply loop, from basic elimination stray current and long-term corrosion influence thereof.
2, the utility model adopts the rail insulation of two contact rails and rolling stock to come, form independently rolling stock traction power supply loop, can eliminate rail and the earth step voltage, not entail dangers to personal safety, simultaneously because the contact rail (power rail and backflow rail) of the left and right sides is bigger apart, can avoid short trouble, improve power supply reliability.
3, the utility model can be implemented at newly-built rail line, though can increase disposable construction investment in early stage, can avoid loss that the stray current long-term corrosion causes and disposable apparatus investment and the long-term maintenance cost of stray current protective equipment.
4, the utility model is used instead when being subjected to the electricity wheel, the cliding friction electric means can be become the electric means based on friction of rolling, thereby significantly reduce abrasion, strengthens being subjected to electrical stability and service life of equipment.
5, the utility model can be cancelled contact system, is conducive to urban look.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
