DEVICE FOR FEEDING, AT LEAST ONE ONE ELECTRIC RAIL COIL OF RAIL VEHICLE, ON LEAST, ONE ELECTRIC PULSE

摘要

1. Device (28) for providing at least one electric coil (9) with at least one electric current pulse for selectively magnetizing or demagnetizing at least one magnetically-solid magnetizing constant material, segment (5) of the brake electromagnet (2) of a rail vehicle, characterized in that it contains a) at least one configured to supply electricity from at least periodically located energized on-board electrical network of the circuit (32) of the current of the on-board electrical network of the rail vehicle, a long-term energy accumulator (34), b) at least one magnetizing current circuit (38), with a voltage transformer (36) for converting the voltage supplied from the long-term energy accumulator ( 34) the voltage of the onboard electrical network to a predetermined magnetization voltage and for charging at least one energy accumulator (40) of a multi-ampere current with electricity under a magnetizing voltage, as well as with seated in an electrically conductive connection, on the one hand, with an energy storage battery (40) of a multi-ampere current, and, on the other hand, with an excitation coil (9), a switching device (42), through which, depending on the control given from the control device (44) signals based on the multi-ampere current of electricity accumulated in the energy accumulator (40) and selectively changed with respect to the direction of the current flow, current pulses are transmitted to the excitation coil (9). 2. The device according to claim 1, characterized in that the long-term en
