Automatic passing phase separation control device and passing phase separation control system for multi-locomotives

Abstract

The invention provides an automatic passing phase separation control device and a passing phase separation control system for multi-locomotives. The automatic passing phase separation control device comprises a phase separation section functional position signal receiving unit (10) for receiving and recognizing a phase separation section functional position signal, a level acquiring unit (20) for acquiring a level signal of a control handle, and a passing phase separation control unit (30) for receiving the phase separation section functional position signal from the phase separation section functional position signal receiving unit (10) and receiving the level signal from the level acquiring unit (20), outputting a level control signal based on the pulse width modulating form of the level signal according to the received functional position signal to control lifting of the level, and outputting a secondary control signal and a main circuit breaker on/off control signal to respectively control starting and shutting of a secondary machine and the switch off and switch on of the main circuit breaker. The passing phase separation device and system are beneficial to stably finish passing phase separation processes of a single locomotive and the multi-locomotive.

Description

technical field [0001] This application relates to the field of phase-segmented control of electric locomotives. Background technique [0002] Since the railway traction catenary uses single-phase power frequency AC power supply, in order to make the three-phase balance of the power system and improve the utilization rate of the power grid, the railway traction catenary adopts segmental commutation power supply, and there are insulating parts in the commutation phase. The two-phase catenary is separated, which is called the phase separation zone here. When the locomotive passes through the phase-separation zone, if the on-board electrical appliances are working, it will pull out a large arc, which will easily cause a phase-to-phase short circuit. Therefore, when the locomotive passes through the phase separation zone, the main circuit breaker on the locomotive needs to be disconnected for protection. The traditional phase splitting method for electric locomotives is that t...

AI Technical Summary

Problems solved by technology

The phase separation time of each locomotive in the reconnection locomotive is different, and the phase separation process cannot be controlled by the master locomotive at the same time. Therefore, the current automatic phase separation system is not suitable for the application of reconnection locomotives
