Electric locomotive system and neutral section passing system thereof

The utility model discloses a neutral section passing system, which is characterized in that 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 the electric locomotive can pass through the non-electric area in an electrified manner, and when the power supply device breaks down, the contact net can be powered by the power supply device. 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
