Abstract
The invention discloses a pantograph pan with a flexible electric brush. The pantograph pan is mainly composed of three parts including a rigid conductive panel, the flexible electric brush and a bottom plate. The rigid conductive panel can be a pure-carbon plate or a metal impregnation carbon plate or a powder metallurgy plate or a carbon fiber enhanced composite carbon plate. The flexible electric brush is an electric brush made of conductive fibers. The conductive fibers can be carbon fibers, graphite fibers or metal fibers or fibers achieved by blending the carbon fibers, graphite fibers and metal fibers to a scale, and are also doped with high temperature resisting aramid fibers of a certain scale. The rigid conductive panel and the flexible electric brush both adhere to the bottom plate through conductive glue.

Description
Technical field
The invention belongs to the pantograph device technical field of track train, be specifically related to a kind of pantograph pan with flexible brush.
Background technology
Pantograph is that electrically-driven car obtains the electrical equipment of electric energy from contact system, is arranged on the roof of locomotive or motor-car by insulator.When pantograph rises, its slide plate contacts with contact line conducting wire, from contact line conducting wire by flowing power taking for hauling engine and other electrical equipment.Current most popular single arm pantograph is made up of parts such as slide plate, upper frame, lower arm rod, underframe, rising bow spring, transmission cylinder, supporting insulators, its middle slide plate is one of most important parts of pantograph, slide plate and contact line conducting wire constitute the special friction pair of a pair machinery and electrical couplings, its principal feature is slide plate high-speed slide, is got heavy current from contact system.Due to mechanics and the electrology characteristic of Pantograph-OCS system complexity, cause the working environment very severe of slide plate, a lot of problem such as vibration, frictional heat, arc erosion is faced in operational process, topmost be exactly slide plate abrasion lost efficacy, for carbon system slide plate (comprising pure carbon plate, metal-impregnated carbon plate and fibre reinforced compound carbon plate etc.), the risk also there is block, fractureing, come off.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.
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.
The abrasion of slide plate and contact wire are except mechanical friction loss, more importantly arc loss, it is the serious ablation behavior that electric arc occurs under heat, power effect, cause the oxidation of contact surface, melting, evaporation, splash etc., cause the uneven of contact wire and pantograph pan, increase bow net contact resistance, localized hyperthermia even deposite metal and produce fusion point is there is at mating surfaces, 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 must affect that bow net is stable to be flowed, damage contact wire and slide plate, increase maintenance load, then cause contact wire to rupture time serious, 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.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, as effectively do not overcome the harm that bow net electric arc causes, will directly restrict the development of China Express Railway.
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 is excessive and contact resistance fluctuation in operational process be current pantograph rigidity slide plate by flow way to take power be difficult to the defect that overcomes.Although research staff takes all measures for a long time, for example exploitation low-resistivity sliding material, as metal-impregnated carbon slide, powder shaped charge liner, titanium silicon-carbon system high-speed train pantograph slide plate etc., but because the conduction amount of speckle of slide plate rigid surface and contact system contact surface cannot effectively increase, the effect therefore by means of only improvement slide plate material minimizing electric arc is not bery desirable.Visible, for pantograph pan traditional at present by stream way to take power, unpractical for thoroughly eliminating the arc phenomenon of Pantograph-OCS system, 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.
Rub by the defect flowed existing for way to take power for traditional pantograph rigidity slide plate and contact system, the present invention devises a kind of pantograph pan with flexible brush, its principle increases by one piece of flexible brush be made up of conductive fiber on pantograph rigidity slide plate basis, when pantograph slides forward, the wire of contact system is except contacting with rigidity sled surface, contact with the conductive fiber that flexible electrical brushes simultaneously, conductive fiber from the bottom of contact wire, side all forms close contact, form multi-faceted solid friction, reach the object by stream power taking.
