ELECTRIFIED RAILWAY SYSTEM WITHOUT NEGATIVE SEQUENCE THROUGHOUT WHOLE PROCESS AND WITHOUT POWER SUPPLY NETWORKS AT INTERVALS Russian patent published in 2018 - IPC B60M1/12 B60L9/26 

FIELD: transportation; electrical equipment.

SUBSTANCE: invention relates to the power system of an electrified railway without reverse sequence in the whole process and without power supply networks at intervals. In the method, the power system consists of an external power supply system, an external power supply input system, and an internal power supply system. In the external power supply system, one means is provided for a path in one direction and a path in the opposite direction of a railway. These two means are parallel, symmetrical and identical to each other. For these means, a plurality of positioning devices are provided as consoles on the upper parts of a number of anchor supports. Two support cables are attached to each positioning device as consoles. These cables are parallel to each other. Each carrying cable is fixedly connected to one end of the catenary suspension. And the other end of the suspension is connected to the power supply cord. Both carrier cables, both catenary suspensions and both power supply wires are parallel to each other and mutually insulated to protect against short circuits. Said catenary suspension is located between the carrier cable and the power supply contact wire. Said catenary suspension transmits the load of the contact wire of the power supply to the anchor section support through the carrier cable.

EFFECT: negative sequence current is reduced, which is caused by the asymmetry of the accumulation of selection error in the whole process.
