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.
MCS2.1 Background control cabinet of trolley bus is mainly used to convert the AC voltage of rectifier transformer into 1500V or 750V 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.
The ISMC cable protection Cabinet is designed to provide protection of DC cables of traction substations of urban electric transport using control coresSHZK performs the following functions
