High Voltage Switchgear
DC traction power supply cabinet engineered for metro, light-rail, tram, and mining traction networks. It steps down and rectifies incoming AC mains to a regulated DC output — typically 750 V or 1500 V — supplying the overhead catenary or third-rail system. Designed for continuous duty in harsh traction environments, the cabinet integrates high-power rectifier modules, DC feeders, protective relays, and remote-signaling interfaces for comprehensive supervision.
Key technical aspects include forced-air cooling for the rectifier stacks, overvoltage and undervoltage protection, short-circuit current limiting, and ground-fault detection. The cabinet supports both 12-pulse and 24-pulse rectifier configurations to reduce harmonic distortion on the AC side, which is increasingly required by utility grid codes.
Typical applications span metro line depot substations, mainline railway auxiliary power, mining overhead-trolley systems, and port container-handling equipment. The enclosure is built to IP3X minimum with a steel-frame structure that resists vibration and airborne contaminants common in tunnel and mining environments.
Standards compliance: IEC 62271-1 (common specifications), IEC 60146 (semiconductor converters), and relevant traction – power standards such as GB/T 10411 (DC switchgear for traction) and EN 50163 (supply voltages of traction systems). Available with RS485 or Ethernet communication for integration into a SCADA or depot management system.
Backed by Hubei Shiji Senyuan Electric Group — a high-tech enterprise with 70+ national patents and 18 years of power equipment manufacturing experience — this traction cabinet is supplied with complete FAT (factory acceptance testing) documentation, wiring diagrams, and packing for sea-freight export.
