Compact current rectifier KVPP

DCdiodeindustrial

Metal-clad rectifier semiconductor substations (hereinafter KVPP) are used for power supply of 230 V DC consumers, DC power supply of industrial plants workshop networks, including electric drive. KVPP includes rectifier units of V-TPED series (converter sections + RESIBLOC® transformers), cabinets with automatic equipment, busbar bridges. Main specific features: production of KVPP rectifiers with 3-phase neutral rectification circuit and paralleling reactor, as well as 3-phase bridge rectification circuit to satisfy any Customer's requirements; rectifiers successfully passed type tests in IPH Institut test center (Berlin, Germany) and meet EN 50328 and IEC 60146-1-1 standard requirements; rectifier protection, control and diagnostics system ensures monitoring of each diode parameters in dynamic mode during rectifier operation, as well as event logging, visualization of temperature and voltage distribution, and other diode parameters. Key benefits: innovative circuit and process design solutions; microprocessor-based protection, diagnostics and control system, Web interface availability; minimum maintenance requirements; minimum diode replacement operations; rectifier power part is made using the technology of maintenance-free contact joints; monitorable force of diode pressing to the cooling units due to calibrated elements in the power assemblies; long lifetime; low maintenance costs. Application fields: industrial enterprises workshop DC networks. Power diodes Power pill diodes 2500 А, 25th grade, are applied in the rectifier converting sections.
