SYSTEM TO CONTROL POWER SUPPLY DIVIDER OF AC TRACTION SYSTEM OF ELECTRIFIED RAILWAYS Russian patent published in 2007 - IPC B60M1/10 B60M3/00 

Abstract RU 2291069 C2

FIELD: electrified railways.

SUBSTANCE: invention relates to control systems of power supply dividers of ac traction system. Proposed system contains signal box, communication line, switch connected between two sections of buses of single-track section sectionalizing post, to first section of which first feeder of contact system is connected supplying contact system, and to second section of buses second feeder is connected supplying contact system. Contact system between points of connection of feeders is separated by air gap. Isolation transformers are connected to communication line on sectionalizing post and on signal box. Secondary winding of each transformer is divided by capacitor. Block-section occupied relay contacts are connected in parallel to capacitor on signal box, and on sectionalizing post series-connected dc supply source and current relay are connected parallel to capacitor.

EFFECT: improved reliability.
