Description
Technical field
The present invention relates to a kind of contact system wind-proof device, particularly a kind of self-tension wind resisting device for electrified railway contact line and using method thereof.
Background technology
Develop rapidly along with the China railways cause, Railway Reform deepens constantly, in the process of progressively moving towards market-oriented management, in order to give full play to the leading role of railway transportation, assurance is stood on the invincible position in competing with the same industry, further improving on the basis of good service, speed-raising work has epoch-making historic significance, but in the speed-raising process, the performance of safety and this contradiction at a high speed more and more sharp-pointed, particularly electrified railway, existing its advantageous advantage, its extraordinary restraining factors are arranged again, and wherein contact net equipment is whether in good condition, how could compress to greatest extent or eliminate because of the interference that fault brings to railway transportation of shaking of contact system wind be an open question.And,, become the principal element that influences the contact system safe operation because the fault that wind action causes has accounted for sizable ratio to the statistical results show of all faults of contact system.
The contact system of electric railway is divided into flexible contact system and rigid contact net.Rigid contact net mainly is used in subway and tunnel, and flexible contact system range of use is very wide, and ground and underground electric railway all can adopt.The contact suspension that flexible contact system adopts mainly is divided into tramway type suspension equip ment and overhead contact line with catenary, because the difference of the mode of casting anchor, overhead contact line with catenary can be divided into semi-auto-tensioned catenary equipment and auto-tensioned catenary equipment.So-called quasicompensation meter has only contact wire that the tension force effect is arranged and catenary is the dead anchors in two ends, and full compensation is that contact wire and catenary all have the tension force effect.Press the number of catenary, overhead contact line with catenary also can be divided into suspension of strand shape and multiple overhead contact line with catenary.Just use maximum strand shapes to hang, comprise again that wherein simple overhead contact line with catenary and elasticity strand shape are hung.What use always in China's electrified railway is that elasticity strand shape is hung.
Contact net equipment has following several characteristics because of the particularity of its effect and structure:
(1) contact net equipment is no standby in operational process, in case et out of order will directly influence the railway transportation order.
(2) open-air operation, environment is abominable, is subjected to influence that external factor changes very greatly, and particularly strong wind is very big to the contact system security implication.
(3) contact wire of the pantograph of electric locomotive and contact system realizes getting stream in the cliding friction process, and this just requires contact net equipment must have better elastic and stability.
(4) complex structure of contact system, incidence is big under the faulty condition.
Overseas high speed overhead contact line type can be classified as three classes basically: be the multiple chain type hanging of representative with Japan promptly, be the simple chain suspension of representative with France and be the elastic chain type hanging of representative with Germany.
Japan has opened the Tokaido the Shinkansen of article one electrified railway-Tokyo～new Osaka in the world on October 1st, 1964, and contact system adopts synthetic multiple chain type hanging mode, and contact wire (Cul10) tension force is 10kN, and the highest overall trip speed is 220km/h.At present the highest overall trip speed in the Shinkansen of Japan is 300km/h, and to plan a newly-built overall trip speed the highest be the electrified railway of 360km/h, and contact system intends adopting the multiple chain type hanging (contact wire tension force is 25KN) of heavy type of 6t system.Though elastic chain type hanging was not adopted in the electrified railway of Japan, it also did comparatively deep research to elastic chain type hanging.
To have built up total length September nineteen eighty-three be Paris～Lyons (southeast line) article one electrified railway of 426km in France, employing be elastic chain type hanging, contact wire (CdCul20mm) tension force is 14kN, overall trip speed is 270km/h.In June calendar year 2001, the Mediterranean line of France is open-minded, and the highest overall trip speed is 350km/h, is the present in the world the highest circuit of overall trip speed, and contact system adopts BZ116+CuSn150/CuMg150 to compensate simple chain suspension entirely, and contact wire tension force is 25KN.
Germany is summing up on the basis of Re75, Re100, four kinds of standards suspensions of Re160, Re200 in the mid-1970s, developed Re250 standard contact suspension, and respectively at the electrified railway of in June, 1991 and in June, 1992 having opened Mannheim～Stuttgart and Hanover-Wei Ercibao, the highest overall trip speed is 250km/h, what adopt is elastic chain type hanging, and contact wire (Ris120mm) tension force is 15kN.At the initial stage nineties, Germany has developed Re330 standard contact suspension again, and the highest overall trip speed can reach 330km/h, still adopts elastic chain type hanging, and contact wire (Riml20mm) tension force is 27kN.In August, 2002, open and drop into trail run by Siemens Company design-calculated Cologne～Lay mattress/U.S. mattress electrified railway, contact system adopts SICAT-H1.0 type (be similar to Re330, but system height being 1600mm) elastic chain type hanging.What Germany's electrified railway was walked all the time is the elastic chain type hanging road, and the development tendency of German high speed contact system is: the structure of contact system is tending towards simplifying, and near the elastic hanger the hitch point is arranged and is tending towards normalisation; The tension force of contact wire is progressively improving, to adapt to higher speed; The maximum outreach of propping up intercolumniation is reduced to 65m by 80m, to reduce the average elasticity of contact system, improves the safety and the reliability of contact system.
From the development of overseas high speed contact system, total trend is:
(1) simplifies the structure of contact system as much as possible, to improve the reliability of contact system.
(2) under the certain condition of material, improve the tension force of contact wire as much as possible, improve overall trip speed with the velocity of wave motion that improves contact wire.
(3) actively develop and exploitation and catenary ' s parameters and the overall trip speed high speed pantograph that is complementary.
Design and construction from present contact system, prevent that because of wind loading causes fault mainly be to consider under the situation of local maximum wind speed, contact wire is no more than 500mm at the maximum offset of span centre, in the actual operation maintenance, also just consider in the location, air port, bent slow location dwindles the span of an intercolumniation, sets up windproof support at place, location just, installs the V-type backguy additional in push off mode place.Respectively shown in accompanying drawing 5,6.
Though certain windbreak function has also been played in these measures, fundamentally do not solve the fault that causes because of wind loading, particularly the pantograph and catenary fault that takes place at the locating point place.Though because taked some wind resistance measure in positive push off mode place, only changed the wind resistance of locating point place contact system, not to the most severe zone of wind-induced vibration, just the wind resistance of the span centre of contact system part has any improvement.Along with the weather of each department in recent years is day by day abominable, wind-force is increasing gradually, and the pantograph and catenary fault that causes because of the strong wind reason is also increasing.Seek shake control bumper and suitable mounting arrangements method of contact system wind with development of new and become the task of top priority.
