Description
Technical field
The invention belongs to the pantograph pan technical field of electric locomotive, be specifically related to a kind of flexible pantograph pan not producing electric arc.
Background technology
Pantograph is that electrically-driven car obtains the electrical equipment of electric energy from contact system, is a kind of mechanical component of radial type, is arranged on locomotive or motor-car roof by insulator.When pantograph rises, its slide plate directly contacts with contact line conducting wire, from contact line conducting wire by flowing power taking and being sent to intra-locomotive by roof bus, for hauling engine and other electrical equipment.Slide plate is one of most important parts of pantograph, slide plate and contact line conducting wire constitute a pair machinery and the special friction pair of electrical couplings, and it has following characteristics: have heavy current to pass through when high-speed slide, periodically random variation load, contact, environmental conditions is complicated and changeable.The main failure forms of slide plate be abrasion to limit, for carbon slipper, also exist fracture, the risk of the block that comes off and must changing in time.Slide plate, once lose efficacy, seriously will jeopardize traffic safety, therefore requires the necessary economic security of its use, both little to contact system lead abrasion, self has enough service life, does not affect pantograph contact line relation again.In general, pantograph pan need possess following characteristic: conduction, heat conductivility that (1) is good; (2) sufficiently high mechanical strength; (3) low electrical resistivity and contact resistance; (4) good self-lubricating property; (5) certain resistance to abrasion; (6) good heat-resisting, arc resistance energy; (7) good weather resisting property; (8) good with contact line conducting wire matching performance.Require that there is the features such as price is low, safety good, environmental pollution in addition.
For ensureing pantograph and contact system good contact, in the scope that height of contact wire allows, require that pantograph pan has certain contact (being generally 70-90N) to contact wire, when the pantograph of high-speed motion slips over static contact system, contact system is subject to the impact of pantograph pan contact, so produce dynamic interaction between pantograph and contact system, cause the vibration that Pantograph-OCS system produces specific modality.When vibration acquires a certain degree, can cause the of short duration disengaging of pantograph pan and contact wire, form off-line, produce electric arc and spark, directly impact is flowed, and power supply momentary interruption even can be caused to make train lose tractive force and braking force.And the contact forces of bow net excessive time, though can reduce contact loss rate, contact wire and abrasion of pantograph pan increase, service life shorten.
First the harm of electric arc show there is obvious aggressive action to contact wire and pantograph pan, it is the serious ablation behavior that electric arc occurs under heat, power effect, show as the oxidation of contact surface, melting, evaporation, splash etc., the erosion of often kind of form all can have damage in various degree to contact wire and pantograph pan.The wearing and tearing that electric arc produces cause the uneven of contact wire and pantograph pan, aggravation mating surfaces electric current distributes brokenly, in mating surfaces generation heat spot and little welding phenomenon, if locomotive travels at high speeds, fusion point comes off instantaneously, make contact wire and pantograph pan damaged condition more serious.To corrode and abrasion gently then affects that bow net is stable to be flowed, damage contact wire and pantograph pan, increase maintenance load, heavy then cause contact wire to rupture, cause locomotive operation accident.The another one harm of electric arc is; when bow net electric arc produces; the electric drive system of Traction networks and electric locomotive is linked together by electric arc; electric arc between contact system and pantograph there is pressure drop, after electric arc disappears, if electric locomotive is also in off-line state; the electric current in circuit is then caused to be undergone mutation; produce over voltage, over voltage is propagated on contact system, brings threat can to the insulation of whole Traction networks; Over voltage enters intra-locomotive along pantograph, may cause damage, produce serious influence to the safe operation of electric locomotive to locomotive electric cad system equipment, electronics package etc.3rd harm of electric arc produces high frequency noise, and launch high frequency noise towards periphery when electric arc produces, the communication signal along the line to locomotive and radio signal cause very large interference, can cause the phenomenon such as communication interruption and radio signal inefficacy time serious.High frequency noise also has impact to the control signal of locomotive, is the hidden danger of locomotive safety running.
The operative practice of high speed train shows, the speed of electric locomotive is higher, and the possibility that pantograph is separated with contact wire is larger, and bow net electric arc more easily produces.The pantograph-catenary current collection test display of China once on July 4th, 2006 on Jiao Ji Railway Line, when train operation speed per hour reaches 200km, bow net arc phenomenon is very serious.The operating data display of section for power supply Luoyang, Luoyang east substation and Rong Yang substation, locomotive is 32 at undue phase time owing to drawing electric arc and trip accident to be 2006, and within 2007, be 34, monitoring video was presented at phase-splitting moment, bow net contact place there will be Great Fire Ball, and situation is very serious.Along with improving constantly of China's high ferro running velocity, the train of current 300-350km/h gradually becomes main flow, more speed such as the train of about 500km/h has also been listed in high ferro development program, can predict, as the harm of bow net electric arc effectively can not be overcome, will directly restrict the development of China Express Railway.
The generation of bow net electric arc has the factor of following several respects, and one be the contact of pantograph high speed rigidity slide plate and contact line conducting wire is linear contact lay.No matter how level and smooth contact portion is, always scraggly on microcosmic, even if there is very large contact between slide plate and contact wire, also only has a small amount of point to contact between slide plate with contact system, and these points are called as conduction spot.Because contact surface is little, contact point is few, so contact resistance is very large, flow through the density of current of conduction spot up to 10
5a/cm
2the order of magnitude, so high electric current makes conduction spot temperature rise rapidly and be melted formation electro spark by producing a large amount of heats during contact resistance.Second, the slip of pantograph causes the rapid displacement of conduction spot, and the spot separation formed that is shifted also can produce electro spark, till these electro sparks can be continued until that conduction spot that is new, that be not melted produces, conduction spot separation voltage and breaking current large to a certain extent time show as electric arc.This situation is slided at locomotive and is got that to flow through in journey be recurrent, must be pointed out that now slide plate and contact wire do not occur that machinery departs from or contact deficiency! 3rd, cause the vibration of contact system when pantograph slides.Divide two kinds of situations, a kind of is that " hard spot " run on contact system when pantograph pan impacts as produced phase step type during section insulator etc., causes moment off-line phenomenon of arc discharge; Second case is that contact system periodically fluctuates and causes bow net contact fluctuation of pressure.When contact declines, area of contact reduces to cause conduction amount of speckle to reduce, when pantograph pan and contact wire are separated to a certain degree, contact resistance sharply increases, the heat Fast Heating conduction spot that very high intensity of current produces, makes its temperature rise rapidly until the fusing of contact surface material is even gasified.Be full of under the condition of high-temperature metal steam at contact gap and just form electro spark in very short time, a large amount of electro sparks accumulates electric arc.4th. during the descending operation of pantograph, slide plate contacts or disengages moment with contact wire, and contact point has electro spark or electric arc to occur.Especially should be avoided in get flow larger time current collecting bow lifting in case produce electric arc.
Can find, the factor causing electric arc to produce is a lot, but above the contact resistance of finally all summing up in the point that slide plate and contact system, and contact resistance excessive be that current pantograph rigidity slide plate and contact system cliding friction are subject to flow the born defect of way to take power.Research staff takes all measures for this reason, for example develop various sliding material, as pure carbon slipper (Li Defu etc., carbon slide for pantograph of electric locomotive [P] CN2167888), metal-impregnated carbon slide (Wang Qingshan. about metal-impregnated carbon slide electric locomotive technology, 1995, (3-4): 41), powder shaped charge liner (Hou Saizhang. Liu Ximing etc. block of bow collector of electric locomotive powdered metallurgy copper base slide plate. China YouSe Acta Metallurgica Sinica, 1994. (12): 210), carbon fiber composite slide-plate (Fang Huachan, a kind of high speed railway motor train unit carbon-fiber reinforced carbon integration pantograph pan, CN104709094A) etc., suitable sliding material can reduce electrical resistivity really, can contact resistance be reduced when other condition is constant thus decrease electric arc occur probability, but because the conduction amount of speckle in bow net contact face cannot increase by actv., therefore the effect by means of only improvement slide plate material minimizing electric arc is not bery desirable, the employing of new type slide plate material mainly adds resistance to abrasion or the tension of material, rupture strength, add the service life of slide plate thus decrease maintenance, maintenance, the frequency changed.Suitable Pantograph-OCS system contact is chosen in the another one measure reducing electric arc.During contact change, number, the size of conduction spot also change, contact resistance also changes thereupon, but contact resistance is not linear relationship with conduction number of spots, within the specific limits, only contact resistance can not be made significantly to reduce by increasing contact, therefore, controlling bow net Static Contact pressure is necessary within the specific limits, but subtracts arc effect and remain limited.
Obviously stream way to take power is subject to for now widely used pantograph rigidity slide plate, the arc phenomenon thoroughly eliminating Pantograph-OCS system is wanted to be unpractical, can only by change Pantograph-OCS system vibration characteristic, choose suitable contact, Proper Match material, improve contact wire production technology, improve the methods such as the construction quality of contact system, reduce the electric arc of Pantograph-OCS system as far as possible.
For the problem existing for current pantograph rigidity slide plate, the present invention devises a kind of flexible pantograph pan, be made up of flexible conducting material, have than the pure carbon plate adopted at present extensively or the lower electrical resistivity of metal-impregnated carbon slide, when flexible slide plate contacts with contact system, due to the effect of contact, flexible slide plate is extruded, form V-type depression to a certain degree, the circular-arc bottom face of contact wire, side contacts with sled surface simultaneously, form closely contact fully, even if at the line segment through phase separation point and irregularity, also can not because of impact off-line, more can not due to the vibration of Pantograph-OCS system off-line, thus the basic generation eliminating electric arc, in addition along with the carrying out of wearing and tearing, carbon fiber or the graphite fiber of flexible panel expose, form conduction suede, keep the close contact with contact system always.
Summary of the invention
