Electric locomotive system and neutral section passing system thereof

According to the neutral section passing system, a power supply device can supply power to a contact net of a non-electric area when an electric locomotive passes through the non-electric area under the condition of no fault, so that it is guaranteed that the electric locomotive can pass through the non-electric area in an electrified mode, and when the power supply device breaks down, the contact net is not damaged. Therefore, when the vehicle-mounted controller passes through the non-power area, the main circuit breaker of the electric locomotive can be switched off before the vehicle-mounted controller passes through the non-power area according to the magnetic fields generated by the electromagnetic devices and detected in sequence, and then the vehicle-mounted controller is switched off after the vehicle-mounted controller passes through the non-power area. The main circuit breaker is closed after passing through the non-power area, so that the electric locomotive can safely pass through the non-power ar
