METHOD OF ELECTRIC ENERGY GENERATION DURING MOTION OF RAILWAY VEHICLES AND INDEPENDENT SOURCE OF POWER SUPPLY OF AUTOMATION EQUIPMENT ELEMENTS OF RAILWAY TRANSPORT Russian patent published in 2016 - IPC B61L1/04 

FIELD: electricity.

SUBSTANCE: on the rail U-shaped magnetic conductor is placed which is fitted with the insert formed by permanent magnet and electric winding. The permanent magnet is placed on the magnetic conductor bridge connecting two of its opposite branches under the rail base. One of magnetic conductor branches is attached rigidly to the rail web. The electric winding is placed on another branch of the magnetic conductor which is arranged with the air gap with reference to the rail head. When the wheel flange crosses this air gap its magnetic permeability changes that leads to change of the value of magnetic flux in the closed magnetic circuit. At the expense of this in the electric winding the voltage is generated which is accumulated. The independent power supply consists of U-shaped magnetic conductor fitted with the insert formed by the permanent magnet and the electric winding.

EFFECT: improvement of reliability and efficiency of electric power generation during motion of railway transport.
