[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, all other embodiments obtained by those of ordinary skill in the art without creative work based on the described embodiments fall within the scope of the present application.

[0050] Embodiment 1

[0051] Please refer to Figures 1-8 The present application provides a harmonious type locomotive simulation operation training platform, which comprises a training platform frame 1 and a component mounting plate 2 located at the front of the training platform 1. The training platform frame 1 is made of Q235B profile and steel plate welding, which is firm, stable, durable and the surface is treated with silvery gray paint insulation. Preferably, the training platform frame 1 is 1.8 meters long, 0.8 meters wide, 1.5 meters high and weighs 123.7 kg.

[0052] Further, the component mounting plate 2 is installed on the surface of the training platform frame 1, and the component mounting plate 2 is arranged with a pantograph circuit and a main circuit breaker circuit. The pantograph circuit comprises a one-end circuit, a power supply circuit and a pantograph relay. The input end of the one-end circuit is electrically connected with the power supply circuit. The power supply circuit converts 220V AC voltage into 24V DC voltage through a 220VAC / 24DC conversion module to supply power for the one-end circuit. The output end of the one-end circuit is electrically connected with the pantograph relay, and the one-end circuit controls the working state of the pantograph relay.

[0053] The embodiment takes one of the one-end circuits as an example. The embodiment simulates the action of the pantograph electromagnetic valve in the locomotive by the KA6 lifting pantograph relay. When the KA6 lifting pantograph relay is powered, the simulated wind rushes into the pantograph air bag, and the pantograph is lifted. The KA6 lifting pantograph relay is electrically connected with the pantograph indicator DS1. The pantograph indicator DS1 simulates the working state of the pantograph. The pantograph indicator DS1 is bright, indicating that the pantograph is in the lifting state. The design of the lifting self-resetting switch and the lowering self-resetting switch avoids the damage of the coil caused by the long-time conduction of the control circuit, and reduces the risk of failure.

[0054] Further, the one-end circuit of the pantograph circuit has two, and the two one-end circuits are mirror-connected in parallel. The electric locomotive is provided with two fully functional driver operation ends for control. When one of the one-end circuits fails, the other one-end circuit can take over the work.

[0055] Further, the one-end circuit further comprises the KA2 lifting pantograph self-locking relay and the KA3 lowering pantograph self-locking relay. The KA2 lifting pantograph self-locking relay is electrically connected with the lifting self-resetting switch, and the KA3 lowering pantograph self-locking relay is electrically connected with the lowering self-resetting switch. The lifting self-resetting switch and the lowering self-resetting switch are connected in parallel. When the lifting self-resetting switch is closed, the one-end circuit is conducted, and the KA6 lifting pantograph relay is powered. When the operation of closing the lifting self-resetting switch is cancelled, the lifting self-resetting switch is opened, and the state of the KA6 lifting pantograph relay remains unchanged. When the lowering self-resetting switch is closed, the KA3 lowering pantograph self-locking relay is opened, and the self-locking loop of the KA2 lifting pantograph self-locking relay is cut off. After the self-locking circuit is damaged, the normally open contact of the KA2 lifting pantograph self-locking relay is opened, the KA6 lifting pantograph relay is de-energized, and the simulated lowering state is simulated.

[0056] Further, the one-end circuit further comprises the KA13 pressure switch relay, the pressure switch, the KM1 alternating current contactor, and the auxiliary compressor M1. The KA13 pressure switch relay is electrically connected with the pressure switch. The pressure switch controls the operation of the KM1 alternating current contactor. The KM1 alternating current contactor controls the start and stop of the auxiliary compressor M1.

[0057] When the pressure is lower than the set value required for lifting the pantograph, the contacts of the pressure switch will act, and the subsequent part of the one-end circuit is connected. After the pressure switch is triggered, the one-end circuit is conducted, and the coil of the KM1 alternating current contactor is powered. When the pressure of the auxiliary air cylinder rises to the set value required for lifting the pantograph, the pressure switch detects that the pressure meets the standard, the contacts of the pressure switch reset, and the power supply circuit of the KA13 pressure switch relay is cut off. After the KA13 pressure switch relay is de-energized, the contacts will switch states, and the power supply of the KA13 pressure switch relay is cut off. After the main contact of the auxiliary compressor M1 is opened, the auxiliary compressor M1 stops running, and the air supplement process is completed.

[0058] The one-end circuit further comprises a high-voltage grounding switch S1, a high-voltage isolation switch S2 and a pantograph pressure switch S3, the high-voltage grounding switch S1, the high-voltage isolation switch S2 and the pantograph pressure switch S3 are electrically connected with the first action relay KA14, the second action relay KA4 and the third action relay KA5 respectively, when the high-voltage grounding switch S1 is actuated, both pantograph indicator lights DS1 cannot be lighted; when the high-voltage isolation switch S2 is actuated, the pantograph indicator light DS1 which is isolated with the high-voltage isolation switch S2 and located in the same one-end circuit is not lighted; when the pantograph pressure switch S3 is actuated, the pantograph indicator light DS1 which is located in the same one-end circuit with the pantograph pressure switch S3 is extinguished. The lightening or extinguishing of the indicator light can quickly feedback the working state of the high-voltage system and the pantograph, which is convenient for the operation and fault judgment of the operator. In addition, when the high-voltage grounding switch S1 is triggered, the pantograph indicator lights of the two one-end circuits are extinguished, which strengthens the warning of the high-voltage grounding state to the operator and avoids misoperation. It can be understood that the working function and principle of the other one-end circuit are completely same as the embodiment.

[0059] Further, the input end of the main circuit breaker is electrically connected with the power supply circuit, and the main circuit breaker circuit is electrically connected with the pantograph relays KA6 and KA12 of the two one-end circuits. The power supply circuit converts 220V alternating voltage into 24V direct voltage through a 220VAC / 24DC conversion module, and supplies power for the power supply circuit. The main circuit breaker circuit controls the closing and opening states of the main circuit breaker. The pantograph relays KA6 and KA12 are electrically connected with the main circuit breaker closing indicator light and the main circuit breaker opening indicator light. The main circuit breaker closing indicator light and the main circuit breaker opening indicator light simulate the closing and opening states of the main circuit breaker. The main circuit breaker closing indicator light is connected in series with the emergency button, and the emergency button will stop outputting power after being disconnected, thereby protecting the circuit.

[0060] Further, the main circuit breaker circuit further comprises a main circuit breaker closing self-resetting switch, a main circuit breaker opening self-resetting switch and control power circuit breakers. The main circuit breaker closing self-resetting switch controls the closing of the main circuit breaker, the main circuit breaker opening self-resetting switch controls the opening of the main circuit breaker, the main circuit breaker closing indicator light is connected in series with the emergency button, and the control power circuit breakers are greater than two and are connected in parallel with the power supply circuit.

[0061] Further, the main circuit breaker circuit further comprises a VCBON relay, a VCBOFF relay and a VCB protection relay. The VCBON relay is electrically connected with the main circuit breaker closing self-resetting switch, and controls the closing action of the circuit breaker. The VCBOFF relay is electrically connected with the main circuit breaker opening self-resetting switch, and controls the opening action of the circuit breaker. The VCB protection relay is connected in series with the VCBON relay and the VCBOFF relay, and controls the opening action of the circuit breaker.

[0062] The main circuit breaker power circuit further comprises a control emergency relay and a converter cabinet protection module, and the main circuit breaker power circuit further comprises a control emergency relay, a controller three-position switch and a converter cabinet protection module. The control emergency relay is electrically connected with the controller three-position switch. When the driver controller is in the traction position or the braking position, the control emergency relay loses power and cuts off the main circuit breaker circuit. When the electric locomotive is in the traction or braking state, the main circuit breaker circuit is cut off to prevent the locomotive from being interrupted by the misoperation of the main circuit breaker. When the driver controller returns to the zero position, i.e. in the non-traction or braking state, the control emergency relay is powered on, and the main circuit breaker circuit is allowed to close.

[0063] The converter cabinet protection module collects fault signals of the converter cabinet. When the converter cabinet is abnormal, the control power supply of the converter cabinet is cut off. The converter cabinet protection module collects voltage, current, temperature and other signals of the converter cabinet in real time. When overcurrent, overvoltage, module failure and other abnormal conditions are detected, the control power supply of the converter cabinet itself is immediately cut off to prevent the fault from expanding.

[0064] Further, the main circuit breaker power circuit further comprises a protection switch, and the number of protection switches is greater than two. When any one of the protection switches acts, the main circuit breaker circuit is disconnected. The protection switches of the embodiment include a test position switch, an auxiliary library switch, a main library 2 switch, a main library 5 switch, a primary side overcurrent switch, a main transformer pressure switch and a main transformer temperature switch. Each protection switch is in a normally open state. When any protection switch detects a corresponding fault, for example, when the primary side current exceeds the set threshold, the main transformer fails or the temperature exceeds the safety threshold, the control power supply of the main circuit breaker is directly cut off or a trip command is triggered to cause the main circuit breaker to trip.

[0065] Further, the one-end circuit and the main circuit breaker circuit each comprise an electric key switch, a main control relay KA1 and a total power supply circuit breaker QFO. The electric key switch is electrically connected with the main control relay KA1. The electric key switch controls the power-on of the circuit, and the total power supply circuit breaker QFO controls the power supply state of the one-end circuit and the main circuit breaker circuit. When the electric key switch is closed, the main control relay KA1 is powered on to allow power supply to the one-end circuit and the main circuit breaker circuit. The electric key switch is a trigger end. When pressed, the electric key switch coil power is turned on, and the normally open contact is closed to form a self-lock. After self-locking, the electric key switch remains in the powered-on state, thereby providing stable control power supply to the one-end circuit and the main circuit breaker circuit. When the electric key switch triggers a reset signal, the self-locking is released, and the control power supply of the circuit is cut off.

[0066] Further, the component mounting plate 2 is connected with the pantograph circuit and the main circuit breaker circuit through wires and terminal rows; the component mounting plate 2 comprises a first component mounting plate 21, a second component mounting plate 22, a third component mounting plate 23, a fourth component mounting plate 24 and a fifth component mounting plate 25, the first component mounting plate 21 comprises a reserved PLC device; the reserved PLC can access new functions, and the PLC logic can be edited and modified according to different needs without changing the hardware, thereby reducing the cost.
