The system of acionametno of traction motor and method for selectively isolating fault conditions in a drive system of the traction motor

摘要

Summary "system of acionametno of traction motor and method for selectively isolating fault conditions in a drive system for a traction motor, a traction motor drive system (200) includes a plurality of armature (104) arranged in parallel between you and a pl Uralidade circuit field (105) arranged in series with each other.The plurality of circuits of the field (105) is arranged in parallel with the armature (104). The drive system of traction motor (200) also includes a system for isolation of field (214) including a bypass circuit (215) associated with at least one circuit of the field (105).The system of insulation of field (214) includes a first switch field (216) arranged in series with the plurality of circuits of the field (105), and configured to switch between a first terminal of the bypass circuit (215), and a first terminal field of the at least one circuit of the field ( 105).The system of insulation of field (214) includes a second switch field (217) arranged in series with the plurality of circuits of the field (105) configured to switch between a second terminal of the bypass circuit (215), and a second terminal field of the at least one circuit of the field (105). 1 / 1
