Specifically, the combination of the controllable power supply and the relay has the advantages of simple structure, low cost and power saving.
Of course, the power supply device 1 may be of various types other than the specific form, and the embodiment of the present invention is not limited herein.
Specifically, referring to fig. 2, the present solution changes a permanent magnet in a conventional auto-passing neutral section system into an electromagnetic device 2, and activates the electromagnetic device 2 through a control device 4. The installation mode and the output signal are consistent with the output signal of the traditional permanent magnet.

The magnetic field is stable, shock-resistant, not easy to attenuate, high temperature resistant, corrosion resistant and other excellent characteristics. The electromagnetic device 2 can be welded and fixed at the bottom of the rail by adopting a through steel column and then is filled with special filling.

Specifically, when the power supply device 1 (including the circuit of the phase-a valve set, the circuit of the phase-b valve set, the controller, and the position sensors in fig. 3) operates normally, the standby automatic neutral-section passing system (the onboard controller 3 and the electromagnetic devices 2) does not work, and the locomotive passes through the electric neutral-section zone by being electrified through the power supply device 1. Taking the case that the locomotive enters from the power supply arm a as an example, the position of the locomotive is detected through position sensors J1-J4, and after the controller detects that the locomotive reaches the J1 position, a trigger signal is sent out to control the conduction of the phase valve group a, so that the locomotive enters a dead zone when being electrified. When the locomotive enters the phase change detection point J3 of no-zone, the controller issues a turn-off signal to control the turn-off of the phase valve set a, and then issues a trigger signal to control the turn-on of the phase valve set b, thereby completing the power supply switching of the power supply of the no-zone. And after the standby vehicle completely drives away from the dead zone and passes through the point J4, the control system issues a turn-off signal to control the turn-off of the b-phase valve bank, so that the whole process of passing through neutral section of the locomotive is completed.
When the power supply device 1 has a fault, the control device 4 controls the electromagnetic devices 2G 1-G4 to be powered on, the locomotive enters a vehicle-mounted automatic neutral section passing mode, and after the fault signal disappears, the control device 4 can control the electromagnetic devices 2 to be powered off.
Specifically, in the vehicle-mounted automatic neutral section passing mode, when the electric locomotive runs to a G1(G4) point, the vehicle-mounted controller 3 receives a forenotice ground positioning signal (generated by an induction magnetic field), the vehicle-mounted controller 3 sends a passing neutral section forenotice signal to the micro cabinet, the micro cabinet controls the current of the motor to stably drop to 0 according to the running speed of the locomotive at the moment, a signal for breaking 'main breaking' is sent to the control circuit, and the control circuit controls the locomotive to break a camera and break 'main breaking' (forenotice mode); meanwhile, a buzzer of the cab sounds for 3s to remind the driver of passing through the split-phase area. When the G1(G4) signal fails, the locomotive runs to the G2(G3) point, the vehicle-mounted controller 3 receives the forced ground positioning signal (generated by the induction magnetic field), the vehicle-mounted controller 3 sends an excessive phase forced breaking signal to the micro cabinet, the micro cabinet immediately seals the motor current, and sends a main breaking signal to the control circuit to control the locomotive to break the camera and break the main breaking.
Among them, the G2(G3) signal does not function (forced off mode) when the G1(G4) signal is normally received.
Specifically, after the electric locomotive passes through the dead zone, according to the receiving G3(G2), the vehicle-mounted controller 3 receives a switch-on ground positioning signal (generated by an induction magnetic field), and sends a switch-on 'main-off' signal to the microcomputer cabinet through a pre-informing signal channel, the cab buzzer sounds for 3s to remind a driver that the driver passes through the phase-splitting zone, the microcomputer cabinet sends a switch-on 'main-off' signal to the control circuit, the control circuit controls the locomotive to switch on the phase-splitting camera and the switch-on 'main-off', and after preparation, the microcomputer cabinet controls the motor current to slowly recover to the pre-phase-splitting working condition.
Among them, the G3(G2) signal is not active when the G4(G1) signal is normally received.
As a preferred embodiment, the power supply device 1 is a ground automatic neutral section system.
Specifically, the ground automatic neutral section passing system is a relatively mature system capable of completing the operation of the power supply apparatus 1, and when the ground automatic neutral section passing system is used as the power supply apparatus 1, the design workload can be reduced, and thus the cost can be saved.

Specifically, the magnetic steel has the advantages of simple structure, low price, long service life and the like.
