Circuit breaker Q F1, the first high voltage potential transformer TV1, the first high voltage potential transformer TV1 secondary output line are connected to net pressure and turned
Change the relay KD1 end of contact 11 and 12；The high-voltage connection drawn from the second pantograph PG2 is linked in sequence the second main circuit breaker
QF2, the second high voltage potential transformer TV2.Second high voltage potential transformer TV2 secondary output line is connected to net pressure conversion relay
The device KD1 end of contact 13 and 14；The net pressure switching relay KD1 end of contact 3 and 4 is connected as net pressure signal air switch QA1, net
Pressure switching relay KD1 power supplys are just, power supply is negative is connected to Control System of Microcomputer, and Control System of Microcomputer passes through connection connected with computer
Display screen, computer display are used to show that control information is passed to microcomputer control system by locomotive state information by connection simultaneously
System, the first main circuit breaker QF1, the second main circuit breaker QF2 are switched on and off locomotive high-voltage power supply, the first high tension voltage for control
Transformer TV1, the second high voltage potential transformer TV2 are used to detect the voltage from contact net, the first main circuit breaker QF1, second
Main circuit breaker QF2 is provided with main circuit breaker earthed switch QS10, for that when being safeguarded to locomotive high-pressure side can be made to be abutted against
Ground.
Described net pressure signal air switch QA1 uses the bipolar automatic switch of AC type.
Two soft-key buttons of the first pantograph and the second pantograph are provided with described computer display.
The beneficial effects of the invention are as follows：The reliability of locomotive operation is improved, two main circuit breakers can be made at same
Automatically controlling for main disconnected closure is realized on power car.
Brief description of the drawings
Fig. 1 is the marshalling schematic diagram for the power concentration EMUs that the present invention sets two frame pantographs.
The double main disconnected control system figures of Fig. 2 positions power concentration EMUs power car of the present invention.
Marked in figure：1- high-voltage connections, just, 3- nets press switching relay KD1 power supplys to 2- net pressure switching relay KD1 power supplys
It is negative, 4- connections, 5- equipment protections ground wire, 6- functions of the equipments ground wire.
Embodiment
Invention is described further in conjunction with accompanying drawing 1 and accompanying drawing 2, as shown in Fig. 21 is high-voltage connection, 2 be KD1 nets
Press switching relay power supply just, 3 be that KD1 net pressure switching relay power supplys are born, and 4 between computer display and Control System of Microcomputer
Connection, 5 be that equipment protection is grounded, and 6 be that functions of the equipments are grounded.PG1 is the first pantograph, and PG2 is the second pantograph,
QF1 is the first main circuit breaker, and QF2 is the second main circuit breaker, and TV1 is the first high voltage potential transformer, and TV2 is the second high tension voltage
Transformer, KD1 are net pressure switching relay, and QS10 switchs for main circuit interrupter grounding, for that can make when being safeguarded to locomotive
High-pressure side reliable ground.Computer display is primarily used to show locomotive state information while the display screen can be used to control
Information passes to Control System of Microcomputer, microcomputer control by connection 4 (connection between computer display and Control System of Microcomputer)
System processed is mainly to control the various functions of locomotive.PG1,2 are primarily used to receive electric current from contact net.QF1,2 are mainly used to
Control is switched on and off locomotive high-voltage power supply.TV1,2 are mainly used to detect the voltage of the voltage from contact net.No. 93 lines and
No. 100 lines are two core twisted-pair shielded wires, are grounded using mode single-end earthed.No. 94 lines and No. 100 lines are two core twisted-pair shielded wires,
It is grounded using mode single-end earthed.QA1 is net pressure signal air switch, using the bipolar automatic switch of AC type.
" the first pantograph " and " the second pantograph ", two soft-key buttons are provided with computer display.When driver determines
Using corresponding soft-key button is pressed after which pantograph, information is selected to pass information to Control System of Microcomputer by connection 4,
If driver's selection is the first pantograph, Control System of Microcomputer sends the instruction of KD1 actions, i.e., had between wire 2,3
110V voltages, to KD1 actuation coil, now KD1 actuation coil obtains electric, and KD1 contact changes, i.e. KD1 contact
11 and 3 are connected, contact 12 and 4 is connected now if when the signal of " for detection device use " is normal, and driver, which sends, closes co-host break
Instruction after QF1 can close, now QF2 can not be closed.What if driver selected is the second pantograph, Control System of Microcomputer
The instruction of KD1 actions is not sent, i.e., does not have voltage between wire 2,3, and now KD1 actuation coil must not be electric, and KD1 contact is mended
Change, i.e. the contact 13 of KD1 is connected with 3, contact 14 and 4 is connected now if the signal of " for detection device use " is normal
When, QF2 can be closed after driver sends the instruction for closing co-host break, and now QF1 can not be closed.This function can realize microcomputer control
System is broken to the master of double main off line cars to be automatically controlled respectively.
