Popularization and application of the mode in down town area.Wherein, with lateral rigidity aluminium/steel aluminum compound structure compared with by trajectory, completely newly
The lateral elasticity of exploitation is by stream contact line with low energy consumption, runs low noise, stable and continuous, simultaneous with existing high-speed rail technology by stream
Therefore many advantages, such as appearance degree is high has laterally been obtained quick popularization and application by the design method of stream contact line.
Currently, the rail traffic announced mainly has with de-icing method: (1) CN201611049351.7 discloses a kind of magnetic
Floating train rail de-icing method and system, this method are directed to traditional rigidity and are carried out deicing, the deicing mode by trajectory
By the control to train itself to achieve the purpose that deicing, the safety and reliability of such de-icing method is higher, but the party
Method limits the speed of service of the train under Alpine-cold condition, affects the high efficiency of magnetic suspension train operation；(2)
CN201610728189.5 discloses a kind of standard track deicer, which is mutually tied using mechanical deicing with heat source deicing
Conjunction mode carries out deicing to standard rail track, is carried out due to this method using the mode in orbit for setting up rack,
It cannot achieve the duration deicing to track, need to increase the deicing frequency under conditions of more severe, so as to cause using into
This is higher, and influences the operation shift of train；(3) CN201610950865.3 discloses a kind of track heat source deicer,
The device carries out deicing in such a way that high temperature hot gas blows and sprays, similar with CN201610728189.5, and removing can not duration
Outside deicing and higher operating costs, there is also the defects that cannot achieve quick deicing (to be blowed and sprayed using high temperature hot gas, need to blow and spray dress
Set to stay for some time on track with to ice crystal melt or fall).
Although there are many breakthroughs in China for the clearing ice technology of rail traffic, big multi-track clearing ice technology is to train
It operates normally there is adverse effect, is mainly reflected in and cannot achieve duration deicing, and deicing cost is big, is influencing train just
Often operation.Obviously, existing clearing ice technology does not meet that current city railway train is quick, operation demand of green energy conservation.
