Description
Technical field
The present invention relates to power concentration motor-car technical group field, and in particular to a kind of power concentration EMUs power car is quick
Value, which multiplies and moved back, multiplies method circuit.
Background technology
Power concentration EMUs are a kind of economical stronger motor train unit trains, and utilization and maintenance cost are all than traditional motor-car
Group is superior.Power concentration EMUs difference compared with power-decentralized TDMU is being mainly that the power of power concentration EMUs 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 dynamic
On power car, passenger is not carried on power car.The marshalling type of power concentration EMUs is flexibly 1+1, compartment of power car+n
Power car (16 >=n >=0).It is distant due to two power cars end to end, before crew's preparation value multiplies (drive propulsion car)
Just have to climb up two power cars end to end respectively to go to be powered operation to control load respectively, (it is dynamic driving is exited moving back to multiply
Power car) when be also required to climb up the power operation that two section power cars do cutting-off controlling load respectively.Have a strong impact on crew
Operating efficiency, multiply in value and move back to take the opportunity and lose time, add the meaningless workload of crew.
The content of the invention
A kind of quick value of power concentration EMUs power car of present invention offer, which multiplies and moved back, multiplies method circuit, the invention solves
The problem of be exactly when crew's value multiplies the power car of power concentration EMUs, manipulatable end power car can complete to two save
The input of power car control load power source and cut-out work, reduce the workload of crew.
The technical solution adopted in the present invention is that the quick value of power concentration EMUs power car multiplies and moved back and multiplies method circuit, bag
2 power cars of same circuits structure are included, are connected between 2 power cars by power supply through line with power-off through line, power car
Power supply just drawing the tunnels of Hou Fen tetra-：
The first via connects quick value and multiplies/move back the contact 4 and 3 for multiplying change-over switch SA10 respectively, connected after being drawn from contact 3 after
Electric apparatus coil KEX, power supply is connected to afterwards and is born；
Second tunnel connects quick value and multiplies/move back the contact 6 and 5 for multiplying change-over switch SA10 respectively, is connected to after being drawn from contact 5
The normally opened auxiliary contact KMF of contactor output end and power supply run through line；
3rd tunnel is linked in sequence the normally opened auxiliary contact KMF of relay normally closed contact KE, contactor parallel circuit, contactor
Coil KMX is followed by power supply bearing；
Power car load is connected to after the connection D.C. contactor main contact KM of 4th tunnel.
The quick value that described power supply connects 2 power cars through the both ends of line respectively multiplies/moved back and multiplies change-over switch SA10's
The exit of contact 5 and the normally opened auxiliary contact KMF of contactor parallel circuit.
The quick value that described power-off connects 2 power cars through the both ends of line respectively multiplies/moved back and multiplies change-over switch SA10's
Contact 3.
The beneficial effects of the invention are as follows：Multiply and move back using the quick value of power concentration EMUs power car and multiply method circuit, increase
The strong operability of power concentration EMUs power car, the less workload of crew, improves operating efficiency.
Brief description of the drawings
Fig. 1 is that power concentration EMUs organize into groups schematic diagram.
Fig. 2, which multiplies and moved back for the quick value of power concentration EMUs power car, multiplies method circuit diagram.
Embodiment
In conjunction with accompanying drawing 1 to accompanying drawing 2, the present invention is described further, as shown in Fig. 2 KEX is relay coil,
KMX is contactor coil, and SA10, which multiplies/moved back for quick value, 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
Normally opened auxiliary contact KMF parallel circuit is the parallel circuit of 2 groups of KMF compositions, and power supply connects 2 groups respectively through the both ends of line
The quick value of power car multiplies/moved back drawing for the contact 5 for multiplying change-over switch SA10 and the normally opened auxiliary contact KMF of contactor parallel circuit
Go out end.The quick value that power-off connects 2 power cars through the both ends of line respectively multiplies/moved back the contact 3 for multiplying change-over switch SA10.
SA10 is beaten to " power supply " position when crew's preparation value multiplies power concentration EMUs power car, power car 1 and dynamic
The contactor KMX of power car 2 obtain it is electric, KMX obtain it is electric after KM and KMF closure, due to SA10 be self-replaced type will now recover automatically to
" 0 " position, KMF is closed now to form self-locking circuit to KMX power supplies, KMX obtained when can be long it is electric, when KM can keep long
Closure is continuously this section power car load supplying.Using two KMF primarily to ensureing the reliability of system, as long as there is a pair
This function can be achieved in KMF closures.When crew, which moves back, multiplies power concentration EMUs power car, SA10 is beaten to " power-off " position,
The KEX of power car 1 and power car 2 obtains electric, and KEX obtains conductance and causes KE to disconnect, and KE, which disconnects, shuts off KMX current supply circuit, and KMX loses
Conductance causes KMF and KM to disconnect, and SA10 is that self-replaced type will now recover to " 0 " position automatically, and KE automatically returns to closure position, due to
KMF is already off, and KMX current supply circuit is cut off, so KM, which can be maintained at, disconnects position, cuts off the confession to power car load
Electricity.
