Abstract

The invention discloses an electrical locomotive auto-passing neutral section control system. In the control system, a signal generator used for transmitting passing neutral section anticipating signal is arranged on a vehicle mainframe of an electrical locomotive, wherein the vehicle mainframe comprises a signal receiver used for receiving the passing neutral section anticipating signal, a memory unit used for storing the required time of locomotive neutral section operation, a clock, a speed sensor used for providing the current speed of the electrical locomotive for a controller, the controller used for outputting passing neutral section control signal and restoring the control signal and a contact network connection controller used for controlling a contact network electrical connection device. The timing that the invention executes the auto-passing neutral section operation is accurate and the reliability of the auto-passing neutral section control is high.

Description

technical field

[0001] The invention relates to the field of phase separation control of electric locomotives, in particular to an automatic phase separation control system and method for electric locomotives including single-traction locomotives and double-connected locomotives. Background technique

[0002] In the electrified traction section, the traction power supply network adopts the single-phase power frequency AC power supply mode. In order to make the three-phase balance of the power system and improve the utilization rate of the power grid, the power supply network of the electrified railway adopts segmental commutation power supply. In order to prevent short circuit between phases, adjacent phases are separated by air or insulators, which is called "electric phase separation". Every 20km to 25km on the domestic contact network, there is a power supply dead zone about 30m long, which is called "phase separation zone". Currently, the following manual over-phase co...
