FIELD: electricity.
SUBSTANCE: invention includes traction substation, supply feeders of which are connected to sections of contact network separated by neutral insert with two insulating gaps. High-voltage switch with drive and position sensor are added, as well as sensors of electric stock location, unit of detection of a moment when switch is changed into a different position and unit of data accumulation and transfer.
EFFECT: improved reliability of equipment as a result of reduction of transition processes as electric stock moves passing by a neutral insert, connecting sections of contact network, and improved conditions of electric stock operation when passing by the neutral insert without disconnection of current and without reduction in speed of motion, better labour conditions for locomotive team due to elimination of labour-intensive and responsible operations executed when passing by the neutral insert.
