Ways of protection against slipping and Southwest Atlantic wheelsets electric rolling with valve-inductor electric

摘要

A method of protecting against slipping and skidding wheel pairs of electric rolling stock with the valve-inductor electrically consisting in that when a locomotive wheelslip (Hughes) one or more wheel pairs and changing signals proportional to the acceleration (deceleration) wheel pairs, to a predetermined level generate control signals characterized in that when the signals proportional to the acceleration (deceleration) wheelsets, setpoint produce control signals that change modes elektroprivo systems Yes, related box (yuzuyuschimi) wheel pairs, the motor control mode is a fixed value β voltage pulse applied to the motor winding is changed to the synchronous mode by removing fixing the voltage pulse at the time the control signal, and the control mode restoration produced when the angle duration pulse voltage setpoint.
