DEVICE FOR DEGAUSSING OF INSULATING RAIL JOINT Russian patent published in 2017 - IPC E01B11/54 

FIELD: transportation.

SUBSTANCE: invention relates to the field of railway transport, more specifically, to devices for degaussing of insulating rail joints. A source of three-phase AC voltage (9) energizes a distributed three-phase winding (8) with three-phase current, and the winding develops a traveling magnetic field, which is closed via an inductor core (5), rails (1) and a joint (2). This field degausses the insulating joint (2) and induces vortex current in rails (1). Interaction of these vortex currents with the traveling magnetic field results in a longitudinal electromagnet wave acting at the inductor core (5), under action of which a trolley (3) is put in motion, resting on wheels (4). Since the device for degaussing of the insulating rail joint is in the area of the insulating joint (2) only for the time of degaussing, the device condition is hardly affected by the conditions of the environment surrounding the insulating joint (2).

EFFECT: invention increases reliability of device operation.
