Description
Technical field
Railroad train electric power system is related to railway power supply technical field.
Background technology
Except steam locomotive, diesel locomotive, what is be now more commonly used is exactly electric power machine for the traction of the train operation of the prior art
Vehicle is as traction power.Electric locomotive is to guide to the electric power of power grid above train on locomotive by pantograph.In high-speed cruising
When pantograph can generate huge running resistance (mainly windage because the shape of the pantograph of currently available technology does not possess
Smooth aerodynamic appearance), the big maintenance cost of abrasion between bow net is higher, and contact net it is easy to hang on rolled by wind it is different
Object, such as polybag, kite, such as clearing up not in time can cause pantograph and contact net to damage by pantograph scraping, meeting when serious
Short circuit is caused even to cause fire, seriously endangers traffic safety.
The content of the invention
To overcome prior art Shortcomings, the first purpose of the application is to cancel pantograph, reduces windage.
The second purpose is to reduce the maintenance cost of electric power system.
The third purpose is to avoid contact with the risk that net is brought by foreign matter winding.
It adopts the following technical scheme that achieve the above object：
First, railroad train electric power system
1st, railroad train electric power system, including：Sidle corridor 1, main transformer 2, body frame 3, side bearing 4, axle box 5, bogie
Framework 6, sandbox 7, sandpipe 9, secondary coil bag 10, wheel 11, rail 12, sleeper 13, primary coil bag 15；
It is characterized in that：For main transformer 2 in motor car, secondary coil bag 10 is located at connection locomotive under locomotive
Bottom；
Primary coil bag 15 is on sleeper 13, the position of center line between parallel rail 12.
2nd, railroad train electric power system, it is characterised in that：Secondary coil bag 10 is identical winding with primary coil bag 15.
3rd, railroad train electric power system, it is characterised in that：It is covered with outside secondary coil bag 10 and primary coil bag 15 outer
Shell.
4th, railroad train electric power system, it is characterised in that：Metal is covered with outside secondary coil bag 10 and primary coil bag 15

5th, railroad train electric power system, it is characterised in that：The side wall of outer shell of secondary coil bag 10 and primary coil bag 15 is
Plastic material.
2nd, the application of railroad train electric power system
1st, the application of railroad train electric power system, railroad train electric power system, including：Sidle corridor 1, main transformer 2, underbody
Frame 3, side bearing 4, axle box 5, bogie frame 6, sandbox 7, sandpipe 9, secondary coil bag 10, wheel 11, rail 12, sleeper 13, just
Grade coil bag 15；
For main transformer 2 in motor car, secondary coil bag 10 is located at connection locomotive bottom under locomotive；
Primary coil bag 15 is on sleeper 13, the position of center line between parallel rail 12；
The application of prior art electric power system is：During train operation to neutral section insulator position, first step cut-out traction electricity
The electrical equipments such as machine, split-phase motor, ventilation blower；Second step cuts off power supply for coaches；3rd step disconnects main circuit breaker；4th step waits row
Vehicle slips over non-Electric region with inertia；5th step is closed main circuit breaker；6th step is closed power supply for coaches；7th step closed draw motor,
The electrical equipments such as split-phase motor, ventilation blower；8th step recovers normally travel；
It is characterized in that：Magnetic field is formed for the energization of primary coil bag 15 first, stops the secondary wire of train in orbit
Circle bag 10 generates sensing electric current under the influence of a magnetic field, is supplied the electric power needed for train；
Secondly cancel neutral section insulator, save above-mentioned first, second, third and fourth, five, six, seven, eight step of the prior art；
The first step disconnects power supply for coaches and reduces tractive force, to reduce electrical load；Second step reduces road speed to reduce
Car body rocks；3rd step waits train to pass through irregularity section；4th step recovers power supply for coaches；5th step increases tractive force and improves
Speed is to normally travel speed.
Advantageous effect
1st, contact net can be omitted, completely eliminates bow net friction, saves maintenance cost；
2nd, cancel pantograph and reduce running resistance；
3rd, prevent the foreign matter being suspended to by wind on contact net from breaking pantograph and endangering traffic safety.
