ANTISKED DEVICE Russian patent published in 2008 - IPC B60L3/10 B61C15/08 

FIELD: transport.

SUBSTANCE: antisked device contains shunt circuit attached in parallel with excitation winding of direct current traction motor via switch. This shunt circuit consists of variable-resistance connected in series with diode and inductive element with gate-controlled thyristor connected in series. During spinning of wheel magnetic flux energy accumulated in inductive elements secure slow decrease of excitation flow of traction motor.

EFFECT: stabilisation of magnetic flux excitation of traction motors and prevention of ring fire on collector.
