Description
Technical field
The invention belongs to field of railway transportation equipment, it is related to a kind of enhancing pantograph composite carbon slide plate of carbon fiber veneer
And preparation method thereof and in particular to a kind of enhancing pantograph of the carbon fiber veneer for electric locomotive and EMU be combined
Type carbon slipper and preparation method.
Background technology
Fast Construction with China Express Railway and continuous development, the construction of EMU is also accelerated continuous, just
The quantity of the EMU of China arranges close to 1000 so far, and the quantity of EMU is also being continuously increased.
The operation power resources of electric locomotive and EMU contact line conducting wire at EMU top in frame, leads to
Cross be installed on the pantograph carbon slide at EMU roof top with the top line pressure of 6～8kg and Wire stick close contact with dynamic
Car group synchronously slides, and the high voltage power supply in contact net is transmitted to electric locomotive and the operating of EMUs high-speed electric expreess locomotive, drives at a high speed
EMUs high-speed cruising.So the pantograph carbon slide being installed on EMU top be to ensure that its EMU at a high speed,
One highly important critical component of safe operation, is also classified as vitals by Chinese Railway parent company.This pantograph at present
Carbon slipper all relies on German imported with original packaging product, and imported product delivery cycle is long, and expensive.
Existing electric locomotive and EMU pantograph carbon slide are by carbon bar and strip aluminium bracket conducting resinl
Bonding gained.Lean on carbon bar top and high-voltage fence wire to make carbon top and wire with the top line pressure of 6～8kg in actual motion
High voltage power supply is sent to the high-speed electric expreess locomotive operating of locomotive or motor-car by contact, thus driving electric locomotive and EMU fortune
OK.Carbon slipper also will be same with electric locomotive or EMU while conduction speed sliding with wire.Due to whole
The connection of individual carbon bar only leans on conducting resinl, and carbon materials are all fragility, run into impact and will rupture and fall block.Electric locomotive and high speed motor car
Group is operationally frequently encountered node and suspension clamp of wire etc. because of climate change, and displacement and dislocation shape in the factor such as strong wind
Become hard spot, thus leading to carbon bar so that carbon slipper is interrupted in high-speed slide or destroy block, some even beat carbon bar winged, are only left
Aluminium cradle surface will result in serious traffic safety accident, and this situation also electrical network can be blown cause heavy losses and after
Really.Moreover carbon bar only leans on conductive adhesive with aluminium bracket, adhesive strength is limited, adds carbon slipper operationally due to by the magnitude of current
Very big, add that high-speed friction leads to slide plate to generate heat, slide plate temperature up to more than 400 degree, at this moment will result in conducting resinl and lose sometimes
Effect, and slide plate carbon bar ruptures and comes off and causes the accident.The above such accident of china railway system generation every year will be hundreds of secondary.
Cause locomotive to stop transport to be delayed and rush to repair, the annual therefore more than one hundred million unit of class causality loss in the whole nation.
