The product provides uninterruptible DC power for the equipment of protection, control and driving power, etc. in electrical power plants (single generating unit capacity≤1000MW),hydro-power stations and various substations rated at 35KV~750KV.
■ Flexible systematic wiring and complete configuration, meeting the demand of various projects domestically and oversea.
■ The key devices are developed all independently, with complete functioning units.
■ N+1 rectifier redundant modules running mode (on-line backup), automatic current sharing and restraining, on-line rectifier module draw-out is available. n The microchip-based DC monitor is with powerful functions, i.e. intelligent control on accumulator, monitors the whole DC system, ‘ four- remotes’ (connecting all kinds of general monitoring table via standard communication interfaces and protocols). Its running experience has been more than ten years. Microcomputer monitoring device of LCD main menu interface
■ Automatic adjustment on control bus bar voltage, and automatic lock on voltage dropping silicon chain, so the control bus bar shall be not black out.
n The system is able to be connected with AC inverters or DC220/DC48V converters, to provide appropriate power for computer and communication system.
