Description
Technical field
The present invention relates to power concentration motor-car technical group fields, and in particular to a kind of power concentration EMU power car is quick
Value, which multiplies and moves back, multiplies method circuit.
Background technique
Power concentration EMU is a kind of economical stronger motor train unit train, and utilization and maintenance cost are all than traditional motor-car
Group is superior.Power concentration EMU difference compared with power-decentralized TDMU is being mainly that the power of power concentration EMU all collects
In on power car, by the power car traction not compartment of drive and fixed marshalling is used, main dynamics equipment also concentrates on moving
On power vehicle, passenger is not carried on power car.The marshalling type of power concentration EMU is flexibly 1+1, compartment of power car+n
Power car (16 >=n >=0).Due to two power cars end to end distance farther out, before crew's preparation value multiplies (drive propulsion vehicle)
It just has to climb up two power cars end to end respectively to go to be powered operation to control load respectively, (it is dynamic to exit driving moving back to multiply
Power vehicle) when be also required to climb up the power operation that two section power cars do cutting control load respectively.Seriously affect crew
Working efficiency, multiply in value and move back to take the opportunity and waste time, increase the meaningless workload of crew.
Summary of the invention
The present invention provides a kind of power concentration EMU power car, and quickly value multiplies and moves back and multiplies method circuit, the invention solves
The problem of be exactly that can be completed in manipulatable end power car to two sections when crew's value multiplies the power car of power concentration EMU
Power car controls the investment and cutting work of load power source, reduces the workload of crew.
The technical scheme adopted by the invention is that quickly value multiplies and move back and multiplies method circuit power concentration EMU power car, wrap
2 power cars of same circuits structure are included, are connected with power-off through line by power supply through line between 2 power cars, power car
Positive pole draw tetra- tunnel Hou Fen:
The first via is separately connected quick value and multiplies/move back the contact 4 and 3 for multiplying change-over switch SA10, connected after being drawn from contact 3 after
Electric apparatus coil KEX, is connected to power cathode later；
Second tunnel is separately connected quick value and multiplies/move back the contact 6 and 5 for multiplying change-over switch SA10, is connected to after drawing from contact 5
The output end of the normally opened auxiliary contact KMF of contactor and power supply run through line；
Parallel circuit, the contactor of the normally opened auxiliary contact KMF of third road sequential connection relay normally closed contact KE, contactor
Coil KMX is followed by power cathode；
Power car load is connected to after 4th tunnel connection D.C. contactor main contact KM.
The power supply, which multiplies/moves back through the quick value that the both ends of line are separately connected 2 power cars, multiplies change-over switch SA10's
The exit of the parallel circuit of contact 5 and the normally opened auxiliary contact KMF of contactor.
The power-off, which multiplies/moves back through the quick value that the both ends of line are separately connected 2 power cars, multiplies change-over switch SA10's
Contact 3.
The beneficial effects of the present invention are: using power concentration EMU power car, quickly value multiplies and moves back and multiplies method circuit, increases
The strong operability of power concentration EMU power car, the less workload of crew, improves working efficiency.
Detailed description of the invention
Fig. 1 is that power concentration EMU organizes into groups schematic diagram.
Fig. 2 is that quickly value multiplies and move back and multiplies method circuit diagram power concentration EMU power car.
Specific embodiment
Now in conjunction with attached drawing 1 to attached drawing 2, the present invention is described further, as shown in Fig. 2, KEX is relay coil,
KMX is contactor coil, and SA10 multiplies/moves back for quick value and multiplies change-over switch (self-resetting type), and KMF is the normally opened auxiliary contact of contactor,
KE is relay normally closed contact, and KM is D.C. contactor main contact.2 power cars include power car 1 and power car 2, contactor
The parallel circuit of normally opened auxiliary contact KMF is the parallel circuit of 2 groups of KMF composition, and power supply is separately connected 2 groups through the both ends of line
The quick value of power car multiplies/moves back drawing for the contact 5 for multiplying change-over switch SA10 and the parallel circuit of the normally opened auxiliary contact KMF of contactor
Outlet.Power-off multiplies/moves back the contact 3 for multiplying change-over switch SA10 through the quick value that the both ends of line are separately connected 2 power cars.
SA10 is turned when crew's preparation value multiplies power concentration EMU power car to " power supply " position, power car 1 and dynamic
The contactor KMX of power vehicle 2 obtain it is electric, KMX obtain it is electric after KM and KMF closure, due to SA10 be self-replaced type will restore automatically at this time to
" 0 " position, KMF is closed to form self-locking circuit to KMX power supply at this time, KMX can long Shi get electricity, when KM can keep long
Closure is continuously this section power car load supplying.Using two KMF primarily to guaranteeing the reliability of system, as long as there is a pair
This function can be realized in KMF closure.When crew, which moves back, multiplies power concentration EMU power car, SA10 is turned to " power-off " position,
The KEX of power car 1 and power car 2 obtains electric, and KEX obtains conductance and KE is caused to disconnect, and KE, which is disconnected, shuts off the current supply circuit of KMX, and KMX loses
Conductance causes KMF and KM to disconnect, and SA10 is that self-replaced type will restore automatically at this time to " 0 " position, and KE automatically returns to closure position, due to
KMF is already off, is cut off to the current supply circuit of KMX, so KM, which can be maintained at, disconnects position, cuts off the confession loaded to power car
Electricity.
