Description

technical field

[0001] The invention relates to an automatic phase separation system and an automatic phase separation method for electrified railway divisions. Background technique

[0002] my country's electrified railway generally adopts single-phase power frequency AC system. In order to make the three-phase load of the power system as balanced as possible, the electrified railway often adopts the scheme of alternating phase sequence and phase-separated partition power supply. The adjacent power supply intervals at the phase-separation partition are divided by air or insulators to form insulating electrical phase separation, referred to as electrical phase separation or phase separation.

[0003] In order to prevent electric locomotives from burning out catenary suspension components due to arcing through phase separation, and even causing accidents such as phase-to-phase short circuit, when the train is over-phase-splitting, the driver needs a series of manual operation...
