Abstract

The invention is applicable to the railway electric locomotive field, and provides an automatic neural section passover control method of an electric locomotive, a device thereof, and the electric locomotive. An RF locator card is arranged on an overhead contact, an RFID location reader is arranged on a roof and used for identifying the RF locator card, a vehicle host computer calculates and calibrates distance between the locomotive and a front section card or a phase point prediction card according to location information of the RF locator card collected by the RFID location reader on the top and kilometer post data read by the vehicle host computer from a TAX box as well as current speed of the locomotive, and performs on / off blockout control with the location information of the RF locator card as main means and the kilometer post data as supplementary means in a neural section passover area so as to ensure optimal blockout position from calculation output and reduce speed loss, meanwhile, the dual locating technology also ensures safety and reliability of the automatic neural section passover of the electric locomotive, avoid missed neural neutral section detection, and provide convenient installation and maintenance.

Description

technical field

[0001] The invention belongs to the field of railway electric locomotives, in particular to an electric locomotive automatic phase separation control method and device and the electric locomotive. Background technique

[0002] my country's electrified railway traction power supply network adopts single-phase power frequency AC power supply mode. In order to balance the three-phase load of the power system and improve the utilization rate of the power grid, the catenary of the electrified railway adopts a segmented commutation power supply mode. At the commutation point, there is a section of insulator to electrically separate the two-phase catenary, which is called a phase separation area. . In order to avoid damage to the power supply equipment by dragging arc, the electric locomotive must coast with power off when passing through the phase separation area. The traditional phase separation method for electric locomotives is that the driver manually operate...
