Description
Technical field
The utility model belongs to traffic for electrical domain more particularly to bipolar rigid contact net formula traffic power supply system.
Background technology
Rail traffic be it is a kind of by track train transported into administrative staff in the way of.Current system is obtained according to track train
Difference, current track traffic power supply mainly include overhead contact line power supply and conductor rail power two ways.Overhead contact line
The contact line of power supply is located at vehicle up direction, is supported by pillar, carrier cable, dropper etc., the pantograph at the top of track train
Carbon slipper and contact line contact obtain electric current；The conductor rail and attachment of conductor rail power supply are located at vehicle bottom side, by exhausted
Edge holder is supported conductor rail and attachment, and carbon slipper and the conductor rail contact of the collector shoe of track train side obtain electricity
Stream.Overhead contact line power supply is divided into as rigid suspension OCS power supply and rigid contact net power supply.Conductor rail power supply is divided into contact
Power supply, the power supply of lower contact and the power supply of side contacts formula.Either overhead contact line power supply or conductor rail power supply, common trait
All it is that the carbon slipper of pantograph or the carbon slipper surface of collector shoe are in contact with contact line or conductor rail outer surface, is rubbed by sliding
It wipes, to obtain electric energy, driving track train movement.
Current overhead contact line power supply and conductor rail power supply, the carbon slipper of pantograph or the carbon slipper of collector shoe respectively with
Carbon slipper is pressed onto contact line or contact by the contact of contact line or conductor rail by the elastic mechanism in pantograph or collector shoe
On rail, carbon slipper is a kind of relationship of relative sliding contact between each other at work with contact line or conductor rail.Due to sliding
Friction is big to carbon slipper and contact line or conductor rail damage comparison, needs to regularly replace carbon slipper.There are one sliding contacts
Problem is exactly that the carbon dust environmental pollution of carbon slipper abrasion is bigger, and is easy to cause line short.
Rigid suspension OCS is since (such as strong wind, which causes contact line to shake excessive, sleet icing, to be caused for installation accuracy, natural conditions
Can not be by electricity), the factors such as train vibration caused by track unevenness influenced, between pantograph carbon slide and overhead contact line
There are prodigious fluctuations for contact force, unstable so as to cause current carrying quality, generate arc erosion overhead contact line and pantograph etc.
Accident influences traffic safety.In conductor rail power supply mode, there is also current carrying quality shakinesses between collector shoe carbon slipper and conductor rail
Fixed phenomenon, and collector shoe generates impact with end bends, to starting arc, leads to ablation end when by fracture
Elbow and collector shoe.The shortcomings that rigid suspension OCS being can avoid if using rigid contact net power supply.
In addition, the urban transportation is mostly flowed back by rail now, the stray electrical current generated therewith is also
Injury is very serious.Burn into equipment gold of the stray electrical current to the burn into armored concrete metallic structures of rail and its attachment
Belong to the electrochemical corrosion that shell and other underground metal pipelines generate, i.e. stray current corrosion, also referred to as stray current corrosion.For miscellaneous
The scheme for dissipating the prevention of electrolytic corrosion is also very much, and for example rationally setting traction substation, Traction networks are walked using two-side feeding, reinforcement
The insulation against ground of row rail, setting of current drainage cabinet etc..But scheme construction cost is very high, and improvement can only be played the role of, it can not
Thoroughly prevent stray current corrosion.The traction rail and return current rail of 4th rail telegram in reply system use metal rail, resistance to be much smaller than traveling
Rail resistance, so potential difference very little；The insulating support of 4th rail and the holder of common 4th rail are similar, so transition resistance is very
Greatly.Traction rail is responsible for providing electric energy incessantly to locomotive, and return current rail is connected with electric substation cathode cabinet, formed one completely to
The circuit of locomotive power supply.Stray electrical current is not present since return current rail thoroughly insulate with other facilities such as railway roadbeds in four rail power supply systems,
Also it is just not required to consider further that measure and the facility of anti-stray electrical current, is scheme that is optimal, putting things right once and for all.
