Abstract

A power supply system for contactless electric locomotives for a double-track system of transport of goods relates to electrical engineering, namely, to the power supply systems of electric locomotives, for which energy is transmitted by an electromagnetic field and which are used, for example, in the mines dangerous in terms of gas and dust, for a double-track system of cargo transportation. The power supply system includes a traction line consisting of two cables - direct and reverse, a radio-frequency power supply, which is connected to both cables at the beginning of line, and on each of electric locomotives an energy receiver is located with a magnetic conductor and a coil embedded in it and connected by a rectifier with a capacitive energy storage. The direct and reverse cables at intervals along the line not exceeding a step of transposition, are shifted in the horizontal plane in perpendicular to the direction of motion and without break of an electric circuit at a distance lk+b and lk-b, respectively, where lk - distance of longitudinal axes of tracks; b - distance between the cables of line. The technical result is reduction of power losses in the cables of traction line, reduction of the length of cabling and double reduction of reactive power of the capacitors providing a state of voltage resonance in the electrical circuit.
