Traction Rectifier Cabinet Of Trolley Bus
Brief introduction
Traction rectifier cabinet of trolley bus is mainly used to convert the AC voltage of rectifier transformer into 825V or 600V DC for subway or light rail vehicle traction, as the critical link of AC and DC conversion. In order to reduce the influence of harmonic currents on the grid, the rectifier currently adopt single cabinet 12-pulse rectification (composed of two three-phase 6-pulse full-wave rectifier bridges in parallel), and the traction substation generally consists of two rectifier units in parallel operation constituting equivalent 24-pulse rectification.
