Description
Technical field
The present invention relates to electric locomotive technical field, specially a kind of electric power machine car weight joins "Jumper" cable.
Background technology
Electric locomotive, which starts, to be accelerated fast, and climbing capacity is strong, and work is not influenced by severe cold, not waste air when operation, so
It can more play superiority on transporting the mountain route that busy trunk railway and tunnel are more, the gradient is steep.In addition, electric power passenger arranges
Vehicle can provide convenience for car air conditioning and electric heating.Since electric railway capital construction investment is big, equipment skill
Art requires height, and anti-natural calamity ability is poor, therefore electric locomotive is applied be not as extensive as diesel locomotive, it is also not possible to replace internal combustion completely
Locomotive.Electric locomotive does not have air pollution, and is good at maintaining, hundreds of km of scooter when tractor-trailer train, so bullet train base
This is by electric locomotive traction.Electric locomotive is another advantage is that startup and braking can be completed in a short time, this performance
It is more outstanding than steam locomotive and diesel locomotive very much, be particularly suitable for dispatching a car the urban track traffic row that density is high, station spacing is short
Vehicle.Therefore, electric locomotive is paid attention in the world, and countries in the world continue to increase dynamics and develop performance more preferably electric power
Locomotive.Tractive force and climbing capacity the ratio diesel locomotive and steam locomotive of electric locomotive are much greater, are carrying electric power machine car weight mistake
It is big or in the case that the gradient is larger without multi locomotive traction.The biggest advantage is to unlimited strokes for electric locomotive, as long as vehicle
Electrified section is not sailed out of, " would not starve "（Except failure）, without often supplementing combustion as diesel locomotive and steam locomotive
Material.The electric railway at China's initial stage is not very much（Common railway）, so a script non-electrified railway can be selected to carry out electricity
Gasification transformation.Railway speed after electrification innovation will be increased to 160-200km/h from 100-120km/h, can not only contract in this way
The haulage time of short train, moreover it is possible to which the goods train transport for reaching 5000t or more promotes rail transportation efficiency.Nowadays, it moves towards
The China in " high ferro epoch " just greatly develops electric railway, and the speed of electric rail car group is up to 250-400km/h.
Electric locomotive is with power is big, speed is fast, overload capacity is strong, the low, tractive force of heavy burden and acceleration are big for itself, reorganizes and outfit
Activity duration is short, maintenance capacity is few, energy utilization rate is high, running cost is low, be easy to implement multi locomotive traction, can use regenerative braking with
And the advantages that clean environment firendly.Train running speed and load capacity can be improved using electric locomotive traction car team, to significantly
Ground improves the transport capacity and handling capacity of railway, is especially beneficial the speed-raising of old railway.Wide, the Beijing-Shanghai and capital nine in capital in China etc. is dry
Large area starts electric locomotive after line railway carries out electrified upgrading, effectively shortens the tourist on train time；Electric locomotive
Clean environment firendly, when operation, generate exhaust gas unlike steam vehicle or diesel locomotive.Exist for the power plant that electric railway uses
When using fossil fuel, exhaust gas discharge can be controlled, wind-force or the hydroelectric generation of low stain in addition to this can also be used, moreover it is possible to carry
High thermal efficiency.In terms of noise, electric locomotive is at runtime also much than diesel locomotive peace and quiet.Therefore, electric locomotive is very suitable
For being runed in urban rail transit line；In performance, electric locomotive is not required to as being taken certainly as steam locomotive or diesel locomotive
Very heavy engine and fuel can mitigate dead weight, therefore than steam locomotive and diesel locomotive in terms of acceleration and deceleration and most high speed
It is winning, it can further reduce running time, be the first choice of bullet train, EMU etc.；The shortcomings that electric locomotive, is it
Itself there is no power source, electric energy is from external cable or electric rail, in case of the initiation of the force majeure situation such as natural calamity, war is disconnected
Electricity can not just be run, and cause transport to be paralysed, in some instances it may even be possible to cause accident.South China of China in 2008 meets with large area and drops by force
Snow has damaged power supply unit of the railway on the way on line, has caused the electric trains of multiple shifts to stop transport, cause serious passenger stagnant
It stays.Hybrid power is a kind of half-way house, i.e., is additionally equipped with emergency diesel dynamo in electric locomotive or increases and hang diesel oil hair
Motor compartment to deal with the outage condition of burst, but can increase transportation cost；Development, production and the repair of electric locomotive and its
Construction, operation and the maintenance of required electric railway, expense that will be high and high-end technology, lead to whole railway system
Difficulty of construction and maintenance cost are more much higher than non-electrified railway.If in immiseration, sparse population, topography be dangerously steep, weather
Severe wait builds electric railway under environment, will propose rigors to country or local financial burden and scientific and technological level；Electricity
Power locomotive relies on electric railway, and a large amount of power grid electricity rail facility can have some potential safety problems, if someone swarms into wantonly
Railway climbs up roof and will induce electric shock accidents, and the high-voltage fence of electric railway collapses in case of unexpected in Urban Streets
It collapses, also easily causes electric shock consequence.
Motor locomotive joins a kind of cable that "Jumper" cable is critically important in electric locomotive normal use again, in the prior art
It is inadequate for the junction protection of "Jumper" cable, and when needing repairing, dismounting is more inconvenient, is especially needing emergency maintenance
In the case of leverage at cable connection repair efficiency.
