METHOD OF OBTAINING ELECTRIC ENERGY DURING MOVEMENT OF RAILWAY FACILITIES AND AUTONOMOUS POWER SOURCE OF ELECTRIC DEVICES OF GROUND-BASED OBJECTS OF RAILWAY TRANSPORT Russian patent published in 2019 - IPC B60L1/04 H02K35/06 

FIELD: physics.

SUBSTANCE: group of inventions relates to track devices interacting with train. Method of obtaining electric energy during movement of railway facilities consists in the following. U-shaped magnetic conductor is placed under the rail and equipped with an insert from a permanent magnet and a generating electric winding. Insert from permanent magnet is arranged on web of U-shaped magnetic conductor connecting its two opposite branches with air gap. Change of magnetic permeability of the air gap results in change of magnetic flow value in the closed magnetic circuit, due to which in the winding electric voltage is generated, which is accumulated with the help of electric energy accumulator. Change of magnetic flux value is effected by wheel flange action on metal rod from magnetically soft material, which covers air gap of U-shaped magnetic conductor at moment of wheel object rolling. Also, self-contained power supply source of electric devices of railway transport facilities is proposed.

EFFECT: technical result consists in improvement of reliability and efficiency of electric power generation during movement on rails of railway transport.
